Menneskets evolusjon…Genene våre har gjennomgått en 7 mill år lang evolusjonsutviklingHistorisk sett er vi programmert til lite, men naturlig mat og mye slitNår det gjelder utviklingen av menneskets gener, snakker vi om kanskje så mye som 7 mill år med evolusjonshistorie. Homo sapiens er ca år gammel. Faktisk har våre gener forandret seg med 0,1% de siste årene. Fram til midten av det forrige århundret har menneskets hverdag for det meste bestått av lite mat og mye slit. Denne hverdagen er det våre gener er best ”utrustet” til.

21Inflammation, AGING AND CHRONIC DISEASE Chronic systemic inflammation is an underlying cause of many seemingly unrelated, age-related diseases. As humans grow older, systemic inflammation can inflict devastating degenerative effects throughout the body (Ward 1995; McCarty 1999; Brod 2000). Correcting a chronic inflammatory disorder will enable many of the health problems of aging to be prevented or reversed.

23The Causes of Age-Related Inflammation Aging results in an increase of inflammatory cytokines that contribute to the progression of many degenerative diseases (Van der Meide et al. 1996; Licinio et al. 1999).Rheumatoid arthritis is a classic autoimmune disorder in which excess levels of cytokines such as TNF-a, IL-6, IL-1(b), and/or IL-8 are known to cause or contribute to the inflammatory syndrome (Deon et al. 2001).Chronic inflammation is also involved in diseases as diverse as atherosclerosis, cancer, heart valve dysfunction, obesity, diabetes, congestive heart failure, digestive system diseases, and Alzheimer's disease (Brouqui et al. 1994; Devaux et al. 1997; De Keyser et al. 1998).
30The Causes of Age-Related Inflammation (2) In aged people with multiple degenerative diseases, the inflammatory marker, C-reactive protein, is often sharply elevated, indicating the presence of an underlying inflammatory disorder (Invitti 2002; Lee et al. 2002; Santoro et al. 2002; Sitzer et al. 2002).When a cytokine blood profile is conducted on people in a weakened condition, an excess level of one or more of the inflammatory cytokines, e.g., TNF-a, IL-6, IL-1(b), or IL-8, is usually found (Santoro et al. 2002).
31The Causes of Age-Related Inflammation (2) In aged people with multiple degenerative diseases, the inflammatory marker, C-reactive protein, is often sharply elevated, indicating the presence of an underlying inflammatory disorder (Invitti 2002; Lee et al. 2002; Santoro et al. 2002; Sitzer et al. 2002).When a cytokine blood profile is conducted on people in a weakened condition, an excess level of one or more of the inflammatory cytokines, e.g., TNF-a, IL-6, IL-1(b), or IL-8, is usually found (Santoro et al. 2002).
32Elevated TNF-a in well treated hypertension TNF-a levels were measured in a group of people with high blood pressure and a group with normal blood pressure (Verdecchia et al. 2002). The hypertensive subjects taking anti-hypertensive medications had about the same blood pressure as the healthy test subjects.Arterial flow medicated dilation, however, was significantly impaired in the hypertensives and this group also showed higher levels of TNF-a, indicating persistent inflammation despite blood pressure control.This study showed that even when blood pressure is under control, hypertensives still suffer endothelial dysfunction caused by a chronic inflammatory insult.
33Elevated C-Reactive Protein and Interleukin-6 Predict Type II Diabetes Baseline levels of C-reactive protein and interleukin-6 (IL-6) were significantly higher among those who subsequently developed diabetes compared to those who did not. (Pradhan et al. 2001).Women with the higher IL-6 levels were 7.5 times more likely to develop diabetes while those in the higher C-reactive protein ranges were 15.7 times more likely to become diabetic.After adjusting for all other known risk factors, women with the highest IL-6 levels were 2.3 times at greater risk, while those with the highest C-reactive protein levels were 4.2 times more likely to become diabetic.These other diabetic risk factors (such as obesity, estrogen replacement therapy and smoking) all sharply increase inflammatory markers in the blood. These data support a possible role for inflammation in diabetogenesis.
34C-Reactive Protein and IL-6 Predict Death Elevated C-reactive protein, IL-6 and other inflammatory cytokines indicate significantly greater risks of contracting or dying from specific diseases (heart attack, stroke, Alzheimer's disease, etc.).1,293 healthy elderly people were followed for a period of 4.6 years (Harris et al. 1999).Higher IL-6 levels were associated with a twofold greater risk of death.Higher C-reactive protein was also associated with a greater risk of death, but to a lesser extent than elevated IL-6.Subjects with both high C-reactive protein and IL-6 were 2.6 times more likely to die during follow up than those with low levels of both of these inflammation markers.These results were independent of all other mortality risk factors.
35Diet and chronic inflammation Foods can potentially cause or reduce inflammationSome foods cause more inflammation than othersInflammation is mediated through chemical substances called cytokines, which all cells produce - eicosanoids/cytokinesEicosanoids are made of essential fatty acids (omega 3 and 6)Eicosanoid balance is affected by - hormones (among others insulin, cortisol) - type of fat we eat - several micro nutrients (vitamins-minerals)
36Oxidation and inflammation affect all organs, not least the brain, because of its high fat content Everything that contributes to less oxidation and inflammation will have a universall positive health effect
37Oksidasjon og Inflammasjon Oksidasjon står sentraltOksygen er livsviktig men fører til gradvis oksidasjon i kroppenProoksidanter: - mat, økt blodsukker, (flere)umettet fett, stress, røyking, miljøgifter, jern med merAntioksidanter: Viktigst er vårt endogene antioksidantsystem (Glutathion, Liponsyre, Superoxid dismutase, Urinsyre, Melatonin) - vitaminer (for eksempel vit E, C, beta karoten), noen mineraler (for eksempel selen), fytokjemikalier (polyfenoler med mer), stressmestring, god og nok søvn, ren luft, unngå miljøgifter med mer).Antioxidant status kan testes i blodprøve

41Glycation's Role in Inflammation Cooking and Aging have similar Biological Properties Glycation can be described as the binding of a protein molecule to a glucose molecule resulting in the formation of damaged protein structures- AGE or Advanced Glycation Endproducts. (Maillard-Amidori reaction).Many age-related diseases such as arterial stiffening, cataract and neurological impairment are at least partially attributable to glycation.AGE render proteins in the body cross-linked and barely functional. As AGE accumulate, they cause cells to emit signals that induce the production of inflammatory cytokines.
42Glycation IN VIVOGlycation occurs in vivo when blood glucose reacts with body proteins.AGE production is much higher in diabetesConsuming low glycemic foods prevents excessive glycation. The higher the glycemic load (GL) of the diet, the more AGE are produced.The insulin surge that contributes to chronic inflammatory processes.It is also important to avoid over consumption of foods high in omega 6 arachidonic acid (beef, egg yolk, dairy, etc.).
43Cooking, glycation and inflammation Glycation occurs ex vivo during cooking in high temperatures (browning effect) and little or no water (frying, high temp.oven baking, grilling).Approximately 10-20% of AGE in food gets absorbed by the gut.AGE form in the skin, arteries, eye lenses, joints, cartilage, etc.Consuming foods high in AGE might be responsible for the induction of a low-grade, but chronic state of inflammation.
44JUNK FOOD, glycation and inflammation Since most "junk" foods are cooked at extremely high temperatures, it makes sense to avoid French fries, hamburgers, potato chips, fried food and other snacks. These foods not only contain lots of glycotoxins, they also create other metabolic disorders that can induce degenerative disease.
45MethylationChemical reactions that go on in every cell in your body by which methyl groups (one atom of carbon and three atoms of hydrogen) are transferred into another molecule.When this does not happen in a complete manner, intermediary molecules are created, which create free radicals and damage DNA. One of the best examples of this is the creation of homocysteine, which can damage arteries and cause heart disease. Cancer is another possible outcome of this process.To address this, you need to ensure that your diet contains precursors for methylated DNA. These are called methyl donors and can help ensure proper methylation reactions necessary for gene expression take place in your body.
46Methylation, the Homocystein Connection and Inflammation Homocysteine is a toxic byproduct of normal protein metabolism- Enough Vitamin B6, B12 and folate keep it low
47Homocysteine predicts risk for.. Heart attacks, strokes and blood clotsPregnancy problems and birth defectsMemory deficit and Alzheimer’s diseaseDepression (especially in women)Schizophrenia (especially in young men)School gradesPossibly autism… and is easily reversible with optimum nutrition
48Optimal ‘Homocysteine’ Score is below 7-9 (“normal” is up to 15) Around 8-10% of the population has a gene variation (MTHFR) causing excessive homocysteine and need supplementation
498 Ways to Lower Your ‘Homocysteine’ Score below 7-9 Eat enough animal protein (less meat, more fish and vegetable protein, eggs, dairy)- for B12Eat your greensHave a clove of garlic a dayCut back on coffee and black teaLimit your alcoholReduce your stressStop smokingConsider supplementing homocysteine lowering nutrients daily (Vitamin B12, B6 and folate)
50OMEGA FATS, EICOSANOIDS AND INFLAMMATION Omega-3 fatty acids found in fish oil help to suppress the formation of undesirable prostaglandin E2 and promote synthesis of beneficial prostaglandin E3 (Kelley et al. 1985; Watanabe et al. 2000).Similar mechanism as NSAID/COX inhibitors.Gamma - linolenic acid (GLA) induces production of the anti-inflammatory prostaglandin E1 (Das et al. 1989; Fan et al. 1997). What you eat can significantly affect whether you have more of the beneficial prostaglandins (E1 and E3) as opposed to the pro-inflammatory prostaglandin E2.Reducing the consumption of foods that are high in omega-6 fatty acids and increasing the consumption of omega-3 rich foods, such as salmon and other fish, can be beneficial.
51OMEGA FATS, EICOSANOIDS AND INFLAMMATION Limiting foods that convert to arachidonic acid can help reduce inflammation. Arachidonic acid is a precursor to both prostaglandin E2 and the pro-inflammatory cytokine leukotriene B(4) (Brock et al. 1999).Another dietary factor that can lead to high levels of arachidonic acid is the overconsumption of high-glycemic index carbohydrates that cause excess production of insulin (Kreisberg et al. 1983).
52Omega 3 from fish reduce inflammation Omega 3 fatty acid DHA (fish oil) is well documented as to its ability to suppress TNF-a, IL-6, IL-1(b), and IL-8 (Jeyarajah et al. 1999; James et al. 2000; Watanabe et al. 2000; Yano et al. 2000). Fish oil suppresses these dangerous cytokines by up to 90% (James et al. 2000).

Mahfouz MM, Kummerow FA. Burnsides Research Laboratory, University of Illinois, Urbana Experimental Mg2+ deficiency was induced in a group of rats by feeding them a Mg2+-deficient diet for 23 days. They were pair-fed to compare with a control group of rats fed a Mg2+-sufficient diet. In the Mg2+-deficient group the plasma total cholesterol and triglyceride levels were increased while HDL-cholesterol was decreased. In the Mg2+-deficient group the plasma level of thiobarbituric acid reacting substances (TBARS) used as a measure for lipid peroxidation was increased. The increase was attributed to the increased cytosolic Ca2+ in Mg2+-deficiency which can cause: 1) increase of hydro and endoperoxide levels as a consequence of the increase of arachidonic acid release and eicosanoid synthesis in Mg2+-deficiency, and 2) inhibition of the mitochondrial respiratory activity and activation of Ca2+-dependent proteases which may activate the conversion of xanthine dehydrogenase to xanthine oxidase which generates active O2 species. In the Mg2+-deficient group, the fatty acid composition of the liver microsomes indicated a slower rate of conversion of linoleic acid to arachidonic acid which was consistent with the decrease of delta 6 desaturase activity in liver microsomes of Mg2+-deficient rats as measured in vitro. The decrease of delta 6 desaturase activity was attributed to the lower concentration of actual enzyme molecules as a result of the decreased rate of protein synthesis in Mg2+-deficiency. The possible effects of the increased catecholamine release in Mg2+-deficiency are discussedNutr Jul;114(7): Related Articles, LinksInfluence of reduced food intake on polyunsaturated fatty acid metabolism in zinc-deficient rats. Kramer TR, Briske-Anderson M, Johnson SB, Holman RT. The influence of reduced food intake on metabolism of liver phospholipids (PL) in zinc-deficient (ZD) rats was measured. Wealing male Long-Evans rats were fed ad libitum zinc-deficient (2 micrograms Zn/g diet) and zinc-adequate (20 micrograms Zn/g diet) diets for 21 days. A pair-fed (PF) group was included. ZD and PF rats displayed significantly increased levels of linoleic (18:2 omega 6) and dihomo-gamma-linolenic acid (20:3 omega 6). Both ZD and PF rats displayed increased levels of gamma-linolenic acid (18:3 omega 6), but the increase was significant only in PF rats. ZD and PF rats displayed decreased levels of arachidonic acid (20:4 omega 6), but the decrease was significant only in PF rats. Both ZD and PF rats displayed significantly reduced levels of 22:5 omega 6. Both ZD and PF rats displayed increased products of delta 6 desaturation and decreased products of delta 5 and delta 4 desaturation. Significantly increased products of delta 9 desaturation were noted in both ZD and PF rats. ZD and PF rats displayed significant increases in C20 elongation products. ZD and PF rats displayed significantly decreased levels of omega 6 metabolites but not total omega 6 acids. ZD rats showed significantly increased levels of total omega 3 acids and omega 3 metabolites. ZD and PF rats showed significant increases in omega 9 acids but not significant changes in omega 9 metabolites. This study does not indicate that zinc affects the delta 6 desaturase in the metabolism of essential fatty acids. The aberrations previously attributed to zinc deficiency are probably due to the accompanying decreased food intake.Prostaglandins Leukot Essent Fatty Acids Jun;58(6): Related Articles, LinksDual influence of aging and vitamin B6 deficiency on delta-6-desaturation of essential fatty acids in rat liver microsomes. Bordoni A, Hrelia S, Lorenzini A, Bergami R, Cabrini L, Biagi PL, Tolomelli B. Dipartimento di Biochimica G. Moruzzi, Bologna, Italy. Delta-6-desaturase (D6D) activity is influenced by many nutritional and non-nutritional factors, among which one of the most important is aging. D6D activity could be susceptible to the dual influence of aging itself and of nutritional deficiencies, due to the reduced intake and/or absorption of essential nutrients. Particularly, vitamin B6 deficiency might be a crucial factor for D6D activity in aged people. Using 20 month old Sprague-Dawley rats fed a diet with a subnormal level of vitamin B6, we evaluated D6D activity for linoleic acid (LA) and alpha-linolenic acid (ALA) in liver microsomes, and the fatty acid composition of microsomal total lipids. We observed a diminished D6D activity for LA and also for ALA in vitamin B6-deficient animals, being approximately 63% and 81% respectively of the corresponding activity in control rats. As a consequence, significant modifications in the relative molar content of microsomal fatty acids were observed. The content of arachidonic and docosahexaenoic acid, the main products of the conversion of LA and ALA respectively, decreased, LA content increased and a decrease in the unsaturation index was observed in liver microsomes of B6-deficient rats. The foregoing results suggest that the impairment of D6D activity by vitamin B6 deficiency might be an important factor in decreasing the synthesis of n-6 and n-3 PUFAs. This may be particularly important in aging, where D6D activity is already impaired. J Nutr Aug;133(8): Related Articles, Links Dietary trans fatty acids alter the compositions of microsomes and mitochondria and the activities of microsome delta6-fatty acid desaturase and glucose-6-phosphatase in livers of pregnant rats. Larque E, Garcia-Ruiz PA, Perez-Llamas F, Zamora S, Gil A. Department of Physiology, University of Murcia, Murcia, Spain. This study was designed to investigate the effects of three diets with different levels of trans fatty acids and the physiologic status on the physicochemical properties and enzymatic activities of liver microsomes and mitochondria. Three groups of 10 female weaning rats each were fed for 10 wk one of three diets differing in their trans fatty acid contents (Control, 0 mol/100 mol total fatty acids; high, 14.5 mol/100 mol; very high, 30 mol/100 mol). At the onset of adult life (10 wk of age), they were mated. Six rats in each group were killed at the end of gestation (Pregnant rat groups). The four remaining pregnant rats continued to receive their experimental diets until weaning of their litters. Six pups from the litters for each group (3 males and 3 females) were selected and fed the same experimental diet as the dams from wk 3 to 10 of age (2nd generation virgin groups) and then killed. Trans fatty acid levels in liver microsomes and mitochondria rose in parallel with the dietary trans fatty acid content, whereas saturated fatty acids dropped in both organelles with increasing trans fatty acids. Pregnant and 2nd generation adult rats fed trans isomers also had lower levels of cholesterol and a lower cholesterol/phosphorus ratio in their liver microsomes compared with controls. A significant interaction between diet and pregnancy was detected in the activities of delta6-desaturase and glucose-6-phosphatase in liver microsomes. Dietary trans fatty acids decreased the activities of both enzymes but only in pregnant rats. No differences in the fluorescence anisotropy of membranes or the enzymatic activities in liver mitochondria were observed. In conclusion, dietary trans fatty acids significantly lowered cholesterol and the cholesterol/phosphorus ratio in liver microsomes. This effect might contribute to low delta6-desaturase and glucose-6-phosphatase activities in liver microsomes of pregnant rats.J Lipid Res Feb;31(2):271-7.Related Articles, Links Interactions of saturated, n-6 and n-3 polyunsaturated fatty acids to modulate arachidonic acid metabolism. Garg ML, Thomson AB, Clandinin MT. Nutrition and Metabolism Research Group, University of Alberta, Edmonton, Canada. Anti-thrombotic effects of omega-3 (n-3) fatty acids are believed to be due to their ability to reduce arachidonic acid levels. Therefore, weanling rats were fed n-3 acids in the form of linseed oil (18:3n-3) or fish oil (containing 20:5n-3 and 22:6n-3) in diets containing high levels of either saturated fatty acids (hydrogenated beef tallow) or high levels of linoleic acid (safflower oil) for 4 weeks. The effect of diet on the rate-limiting enzyme of arachidonic acid biosynthesis (delta 6-desaturase) and on the lipid composition of hepatic microsomal membrane was determined. Both linseed oil- or fish oil-containing diets inhibited conversion of linoleic acid to gamma-linolenic acid. Inhibition was greater with fish oil than with linseed oil, only when fed with saturated fat. delta 6-Desaturase activity was not affected when n-3 fatty acids were fed with high levels of n-6 fatty acids. Arachidonic acid content of serum lipids and hepatic microsomal phospholipids was lower when n-3 fatty acids were fed in combination with beef tallow but not when fed with safflower oil. Similarly, n-3 fatty acids (18:3n-3, 20:5n-3, 22:5n-3, and 22:6n-3) accumulated to a greater extent when n-3 fatty acids were fed with beef tallow than with safflower oil. These observations indicate that the efficacy of n-3 fatty acids in reducing arachidonic acid level is dependent on the linoleic acid to saturated fatty acid ratio of the diet consumed.Alcohol Aug;34(1):27-33.Related Articles, Links Perspectives on alcohol consumption: liver polyunsaturated fatty acids and essential fatty acid metabolism. Pawlosky RJ, Salem N Jr. Division of Intramural Clinical and Biological Research, National Institutes of Health, National Institute on Alcohol Abuse and Alcoholism, National Institutes of Health, 5625 Fishers Lane, Room 3C-07, Rockville, MD 20852, USA. In this article, subjects diagnosed with alcoholic liver disease are shown to have lower concentrations of several polyunsaturated fatty acids (PUFAs), including 18:2n6, 18:3n6, 20:3n6, 18:3n3, 22:5n3, and 22:6n3, but not 20:4n6 and 22:4n6, nor 22:5n6, in the total lipid extracts of their livers compared with findings for specimens obtained from patients diagnosed with primary biliary cirrhosis and from control subjects. Findings of studies in animals have demonstrated that prolonged alcohol consumption reduces liver polyunsaturate content. However, the effect of ethanol on the elongation/desaturation of essential fatty acids is complex, as in vitro study results indicate that the direction of the effect of alcohol may be related to the dose of alcohol. Findings of studies in hepatocyte cell culture indicate that ethanol increased delta-5 and delta-6 desaturase activities throughout a broad concentration range. In contrast, lower liver desaturase activity has been reported in animals consuming high concentrations of alcohol (36%-40% energy) over a period of several months. Findings from in vivo isotope tracers studies in nonhuman primates and felines indicate that prolonged periods of moderate (mean consumption 2.6 g kg(-1) d(-1) and 1.2 g kg(-1) d(-1), respectively) alcohol consumption had no effect on the uptake of either linoleic (18:2n6) or alpha-linolenic (18:3n3) acids into the plasma and lead to an increased incorporation of these deuterated precursors into 20:4n6 and 22:6n3. Thus, this likely reflects a stimulated, rather than an inhibited, production of long-chain PUFAs. In numerous studies in various species, investigators have documented that alcohol consumption can increase the level of lipid peroxidation in tissues, and sustained periods of ethanol-induced peroxidation can deplete tissues of PUFAs. A hypothesis to rationalize the long-term effects of alcohol consumption on liver PUFA concentration that takes into consideration the effect of ethanol on essential fatty acid metabolism is presented.Int J Tissue React Jun;3(2):89-94.Related Articles, LinksAuto-immunity and prostaglandins. Das UN. Several auto-immune diseases have been described in human beings. Though the exact aetiological agent(s) is not known, clinical or subclinical viral infections and certain drugs are known to induce them. Hyperactivity of B-cells, possibly due to the loss of normal regulatory control by T-cells may account for the increased synthesis of auto-antibodies in these diseases. Prostaglandins (PGs) are known to regulate immune response and fibrous tissue formation. Deficiency of PGE1 and/or thromboxane A2 (TxA2) and excess PGE2 seem to activate B-cells and suppress T-Cell function and enhance fibrosis. Viruses are known to block the enzyme delta-6-desaturase necessary for PGE1 synthesis and thus depress cell-mediated immune response. Drugs known to cause autoimmune disorders also seem to block PGE1 and/or TxA2 synthesis and enhance PGE2 formation which may lead to excess auto-antibody formation. Drugs like colchicine known to enhance TxA2 formation and the biological actions of PGE1 were found to be of benefit in Behcet's syndrome, vasculitis, amyloidosis, scleroderma and in controlling the auto-immune disease in adjuvant arthritis in rats, the renal disease in NZB/W mice and passively transferred vasculitis. Thus altered PG function may play a major role in auto-immunity.

Zingg JM, Azzi A. Institute of Biochemistry and Molecular Biology, University of Bern, Buhlstrasse 28, 3012 Bern, Switzerland. Molecules in biological systems often can perform more than one function. In particular, many molecules have the ability to chemically scavenge free radicals and thus act in the test tube as antioxidant, but their main biological function is by acting as hormones, ligands for transcription factors, modulators of enzymatic activities or as structural components. In fact, oxidation of these molecules may impair their biological function, and cellular defense systems exist which protect these molecules from oxidation. Vitamin E is present in plants in 8 different forms with more or less equal antioxidant potential (alpha-, beta-, gamma-, delta-tocopherol/tocotrienols); nevertheless, in higher organisms only alpha-tocopherol is preferentially retained suggesting a specific mechanism for the uptake for this analogue. In the last 20 years, the route of tocopherol from the diet into the body has been clarified and the proteins involved in the uptake and selective retention of alpha-tocopherol discovered. Precise cellular functions of alpha-tocopherol that are independent of its antioxidant/radical scavenging ability have been characterized in recent years. At the posttranslational level, alpha-tocopherol inhibits protein kinase C, 5-lipoxygenase and phospholipase A2 and activates protein phosphatase 2A and diacylglycerol kinase. Some genes (e. g. scavenger receptors, alpha-TTP, alpha-tropomyosin, matrix metalloproteinase-19 and collagenase) are modulated by alpha-tocopherol at the transcriptional level. alpha-Tocopherol also inhibits cell proliferation, platelet aggregation and monocyte adhesion. These effects are unrelated to the antioxidant activity of vitamin E, and possibly reflect specific interactions of alpha-tocopherol with enzymes, structural proteins, lipids and transcription factors. Recently, several novel tocopherol binding proteins have been cloned, that may mediate the non-antioxidant signaling and cellular functions of vitamin E and its correct intracellular distribution. In the present review, it is suggested that the non-antioxidant activities of tocopherols represent the main biological reason for the selective retention of alpha-tocopherol in the body, or vice versa, for the metabolic conversion and consequent elimination of the other tocopherols.Clin Dev Immunol Mar;11(1):13-21.Related Articles, LinksSuppression of leukotriene B4 generation by ex-vivo neutrophils isolated from asthma patients on dietary supplementation with gammalinolenic acid-containing borage oil: possible implication in asthma. Ziboh VA, Naguwa S, Vang K, Wineinger J, Morrissey BM, Watnik M, Gershwin ME. Division of Rheumatology, Allergy and Clinical Immunology, Department of Dermatology, University of California at Davis School of Medicine, TB 192, Davis, CA 95616, USA. Dietary gammalinolenic acid (GLA), a potent inhibitor of 5-lipoxygenase (5-LOX) and suppressor of leukotriene B4 (LTB4), can attenuate the clinical course of rheumatoid arthritics, with negligible side effects. Since Zileuton, also an inhibitor of 5-LOX, attenuates asthma but with an undesirable side effect, we investigated whether dietary GLA would suppress biosynthesis of PMN-LTB4 isolated from asthma patients and attenuate asthma. Twenty-four mild-moderate asthma patients (16-75 years) were randomized to receive either 2.0 g daily GLA (borage oil) or corn oil (placebo) for 12 months. Blood drawn at 3 months intervals was used to prepare sera for fatty acid analysis, PMNs for determining phospholipid fatty acids and for LTB4 generation. Patients were monitored by daily asthma scores, pulmonary function, and exhaled NO. Ingestion of daily GLA (i) increased DGLA (GLA metabolite) in PMN-phospholipids; (ii) increased generation of PMN-15-HETrE (5-LOX metabolite of DGLA). Increased PMN-DGLA/15-HETrE paralleled the decreased PMN generation of proinflammatory LTB4. However, the suppression of PMN-LTB4 did not reveal statistically significant suppression of the asthma scores evaluated. Nonetheless, the study demonstrated dietary fatty acid modulation of endogenous inflammatory mediators without side effects and thus warrant further explorations into the roles of GLA at higher doses, leukotrienes and asthma.Prostaglandins Leukot Essent Fatty Acids Jun;70(6):521-8.Related Articles, Links Spice phenolics inhibit human PMNL 5-lipoxygenase. Prasad NS, Raghavendra R, Lokesh BR, Naidu KA. $$$Department of Biochemistry and Nutrition, Central Food Technological Research Institute, Mysore , India. A wide variety of phenolic compounds and flavonoids present in spices possess potent antioxidant, antimutagenic and anticarcinogenic activities. We examined whether 5-lipoxygenase (5-LO), the key enzyme involved in biosynthesis of leukotrienes is a possible target for the spices. Effect of aqueous extracts of turmeric, cloves, pepper, chili, cinnamon, onion and also their respective active principles viz., curcumin, eugenol, piperine, capsaicin, cinnamaldehyde, quercetin, and allyl sulfide were tested on human PMNL 5-LO activity by spectrophotomeric and HPLC methods. The formation of 5-LO product 5-HETE was significantly inhibited in a concentration-dependent manner with IC(50) values of mg for aqueous extracts of spices and microM for active principles, respectively. The order of inhibitory activity was of quercetin>eugenol>curcumin>cinnamaldehyde>piperine>capsaicin>allyl sulfide. Quercetin, eugenol and curcumin with one or more phenolic ring and methoxy groups in their structure showed high inhibitory effect, while the non-phenolic spice principle allyl sulfide showed least inhibitory effect on 5-LO. The inhibitory effect of quercetin, curcumin and eugenol was similar to that of synthetic 5-LO inhibitors-phenidone and NDGA. Moreover, the inhibitory potency of aqueous extracts of spice correlated with the active principles of their respective spices. The synergistic or antagonistic effect of mixtures of spice active principles and spice extracts were investigated and all the combinations of spice active principles/extracts exerted synergistic effect in inhibiting 5-LO activity. These findings clearly suggest that phenolic compounds present in spices might have physiological role in modulating 5-LO pathway.Thromb Res. 2003;111(4-5): Related Articles, Links Effective anti-platelet and COX-1 enzyme inhibitors from pungent constituents of ginger. Nurtjahja-Tjendraputra E, Ammit AJ, Roufogalis BD, Tran VH, Duke CC. Herbal Medicines Research and Education Center, Faculty of Pharmacy, University of Sydney, NSW 2006, Australia. BACKGROUND: Based on recent studies, pungent constituents of ginger (Zingiber officinale) and related substances represent a potential new class of anti-platelet agents. The ability of 20 pungent constituents of ginger and related substances to inhibit arachidonic acid (AA) induced platelet activation in human whole blood was studied. METHODS: Anti-platelet activity of the compounds was measured in vitro by the Chrono Log whole blood platelet aggregometer. Molecular hydrophobicity (log P) was measured by reversed-phase high-performance liquid chromatography. COX-1 (ovine) inhibitory effect of -paradol and analogues 1 and 5 was carried out using a COX-1 inhibitor assay kit. RESULTS: -Gingerol, -shogaol, -paradol and gingerol analogues (1 and 5) exhibited anti-platelet activities with IC(50) values ranging from 3 to 7 microM, whilst under similar conditions the IC(50) value for aspirin was 20+/-11 microM. The COX-1 inhibitory activity of -paradol (IC(50)=4+/-1 microM) was more potent than the gingerol analogues (1 and 5) (IC(50) approximately 20 microM). CONCLUSION: The above findings show that gingerol compounds and their derivatives are more potent anti-platelet agents than aspirin under the conditions described in this study. -Paradol, a natural constituent of ginger, was found to be the most potent COX-1 inhibitor and anti platelet aggregation agent. The mechanism underlying AA-induced platelet aggregation inhibition may be related to attenuation of COX-1/Tx synthase enzymatic activity. Lastly, important features of phenolic compounds for inhibition of AA-induced platelet aggregation and COX-1 activity were revealed in this study.J Appl Genet. 2004;45(4): Related Articles, Links Inhibition of cyclooxygenase-2 by diallyl sulfides (DAS) in HEK 293T cells. Elango EM, Asita H, Nidhi G, Seema P, Banerji A, Kuriakose MA. Department of Molecular Biology, Amrita Institute of Medical Sciences and Research Center, Amrita Vishwa Vidhyapeetam (Deemed University), Cochin Kerala, India. Cyclooxygenase (COX) is involved in modulating inflammatory response through the synthesis of prostaglandins. The inducible isoform of the enzyme, COX-2, is overexpressed in some malignant and premalignant lesions. Several preclinical and clinical studies have reported COX-2 inhibition as an effective strategy for chemoprevention. Nonsteroidal anitinflammatory drugs (NASIDs) such as celecoxib, are the most widely investigated COX-2 inhibitors. The oil-soluble diallyl sulfides (DAS) include monosulfides (DAMS), disulfides (DADS) and trisulfides (DATS). They were found to be effective against canine and human tumors, the mechanism of which remains unresolved. We attempted a comparative evaluation of the antiproliferative effect of DAS in HEK 293T cells. The cells were treated with increasing concentrations of DAMS, DADS and DATS. There were significant differences between the IC50 values of DAMS, DADS and DATS. RT-PCR was performed and the expression of COX-2 was compared with that of b actin. DATS inhibited COX-2 gene expression significantly stronger than DAMS and DADS. The data are suggestive of antineoplastic effect of DAS, mediated by controlling COX-2 expression.Mol Psychiatry. 2002;7(8): Related Articles, Links Chronic lithium downregulates cyclooxygenase-2 activity and prostaglandin E(2) concentration in rat brain. Bosetti F, Rintala J, Seemann R, Rosenberger TA, Contreras MA, Rapoport SI, Chang MC. Brain Physiology and Metabolism Section, National Institute on Aging, National Institutes of Health, 9000 Rockville Pike, Bldg 10 Rm. 6N202, Bethesda, MD 20892, USA. Rats treated with lithium chloride for 6 weeks have been reported to demonstrate reduced turnover of arachidonic acid (AA) in brain phospholipids, and decreases in mRNA and protein levels, and enzyme activity, of AA-selective cytosolic phospholipase A(2)(cPLA(2)). We now report that chronic lithium administration to rats significantly reduced the brain protein level and enzyme activity of cyclooxygenase-2 (COX-2), without affecting COX-2 mRNA. Lithium also reduced the brain concentration of prostaglandin E(2) (PGE(2)), a bioactive product of AA formed via the COX reaction. COX-1 and the Ca(2+)-independent iPLA(2) (type VI) were unaffected by lithium. These and prior results indicate that lithium targets a part of the AA cascade that involves cPLA(2) and COX-2. This effect may contribute to lithium's therapeutic action in bipolar disorderPGH2Prostaglandin E1Utvider blodkarHemmer blodproppdannelseSenker blodtrykketHemmer kolesterolsynteseDemper inflammasjonProstaglandin E2Øker LHØker følsomheten i livmorens nerveenderFremmer blodproppdannelseUtvider blodkarØker følsomhet i smertereseptorerFremmer inflammasjonProstaglandin F2dSammentrekning avglatte muskler, livmor,blodkar → menstruasjonssmerterProstaglandin I2Hemmer blodpropp-DannelseUtvider blodkarTromboksan A2Sammentrekker blodkarFremmer blodpropp-dannelse (koagulasjon?)Leukotrien C,D,EFremmerinflammasjonProstaglandin E3Hemmer vekst avKreftcellerHemmer blodpropp-dannelseHemmer åreforkalkningDemper inflammasjonProstaglandin E4

96The Detrimental Effects of Sleep Deprivation Even modest sleep deprivation markedly increases inflammatory cytokines. This finding helps explain why pain flare-up occurs in response to lack of sleep in a variety of disorders.In this carefully controlled study, sleep deprivation caused a 40% to 60% average increase in the inflammatory marker IL-6 in men and women, while men alone showed a 20% to 30% increase in TNF-a. Both IL-6 and TNF are potent pro-inflammatory cytokines that induce systemic inflammation (Vgontzas et al. 1999; Vgontzas et al. 2001).
97Stress and inflammation Stress is an adaptive response common to all living organisms.It involves the activation of the corticotrophin releasing factor (CRF) releasing pathway.The CRF pathway response stimulates over-activity of immunological chemicals. (De Giorgio R, Gastroenterology 1996;110).There is a link between stress and an overactive inflammatory response.Individuals with major depression were shown to have an exaggerated inflammatory response to psychological stress in comparison to those who do not have depression. (Sep. 1, 2006 issue of the American Journal of Psychiatry)
98Vitamin D deficiency and inflammation Increased concentrations of serum TNF-α, an inflammatory marker, were found in women who had insufficient vitamin D levels. Inverse relationship between vitamin D levels and concentrations of TNF-α in a healthy, non-diseased population. (Peterson 2008) This may explain the vitamin's role in the prevention and treatment of inflammatory diseases, including heart disease, multiple sclerosis and rheumatoid arthritis."Adequate vitamin D levels identified in this study are consistent with recent research that suggests the DRI should be increased.”
99Vitamin D deficiency and inflammation To improve vitamin D status and achieve its related health benefits, most people should get at least 1000 IU of vitamin D per day. Exposing 25 percent of the skin's surface area to 10 minutes of sunlight three days per week will maintain adequate levels in the majority of people; however, people with darkly-pigmented skin need more. Only a few foods contain vitamin D naturally, such as fatty fish; other sources are dietary supplements and vitamin-D-fortified foods, including some milkOptimal blood levels of Vitamin D year round: nmol/l (normal range nmol/l)

101Physical Activity and Inflammation Among Apparently Healthy Middle-aged and Older US Adults Study subjects were 3638 apparently healthy US men and women 40 years and older. (Abramson, 2002)Results More frequent physical activity was independently associated with a lower odds of having an elevated C-reactive protein level.Similar associations were seen for white blood cell count and fibrinogen levels.Conclusions More frequent physical activity is independently associated with a lower odds of having elevated inflammation levels among apparently healthy US adults 40 years and older, independent of several confounding factors. The results suggest that the association between physical activity and reduced coronary heart disease risk may be mediated by anti-inflammatory effects of regular physical activity.

129Avslutningskommentarer Fettinntaket i likhet med all annen mat bør være variert. Smør er Ok, men neppe optimal som eneste, eller største fettkilde.Ny studie: Lavglykemisk middelhavskost ”kurerte” 32% med insulinresistens på 12 uker!Lavkarbo med mest rødt kjøtt økte generell dødelighet, mens lavkarbo med stort innslag av vegetabilsk protein/fett (nøtter, frø) reduserte risiko for kreft og hjertesykdom og dødelighet av alle årsaker (Harvard Univ. Fung 2010)Mye, men ikke alt kan bli bedre ved å redusere karbohydratHøyt blodsukker og insulin kan forklare en del, men langt fra alt, ikke minst når det gjelder inflammasjonKjøtt, fisk, kylling, egg øker insulin i vesentlig grad, men ikke blodsukkeret. Mye tyder på at det er kombinasjonen av høyt blodsukker og insulin som er problematisk
130Avslutningskommentarer Ingen eier sannheten.”En ting vet jeg at jeg intet vet” (Sokrates)”Gjør det så enkelt som mulig, men ikke enklere enn det” (A. Einstein)”En ny tanke går gjennom tre stadier: Først blir den latterliggjort, så motarbeidet, til den til slutt blir en selvfølge” (A. Schoppenhauer)Mennesker er ikke like. Man må akseptere at ikke et kosthold er bra for alle”Alt kan være giftig. Det er dosen som avgjør” (Paracelsus)Man må tenke helhetlig ift livsstil. Hygge, gode relasjoner, stress-mestring, nok søvn og fysisk aktivitet har enorm betydningKan man følge lavkarbokosthold hele livet og få hjertesykdom eller kreft? Ja, men man reduserer risikoenMest mulig mat uten tilsetningsstoffer (hva med bacon og nitritter/nitrater?)Måtehold, måtehold, måtehold
