Preventive effect of omega-3 fatty acids on ethinyl estradiolinduced hepatosteatosis in female wistar rat
Authors
Abstract:
BACKGROUND: Hepatic steatosis due to estrogen therapyincreases the activity of inflammatory markers, particularly theactivity of TNFα which in turn induces more lipogenesis.Omega-3 fatty acids are among the negative regulators of hepaticlipogenesis. OBJECTIVES: In this research, the preventive effectof omega-3 fatty acids on estrogen-induced steatosis in rats wasevaluated. METHODS:2 mg/kg. BW/SC of 17α-ethiny-lestrasdiolwere injected into 25 female wistar rats in 5 equal groups(excluding the control group) over 10 consecutive days.Simultaneously, 3 of estradiol-treated groups were orally given250, 500, and 1000 mg/kg. BW omega-3 fatty acids, respectively.At the end of the experiment, plasma ALT, AST, and TNFαlevel were determined. Histopathological changes in the liverwere also identified by the evaluation of samples stained withH&E and Oil Red O. RESULTS: The histological findingsrevealed hepatic microvesicular steatosis and fat deposit inethinylestradiol and, to a lesser extent, in the 250 mg/kg BWomega-3 fatty acids groups. The plasma levels of AST, ALT, andTNFα significantly increased in the ethinylestradiol groupcompared to the control (p

full textEffect of Short and Long-Term Treatment with Omega-3 Fatty Acids on Scopolamine-Induced Amnesia
Two omega-3 fatty acids including docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA) are essential for the physiologic function of neuronal cell membrane. Normal function of neuronal cell membrane requires appropriate composition of fatty in its structure. Present study was designed to compare the effect of short-term and long-term pretreatment with omega-3 fatty acids on scopolamine...

full textOmega-3 fatty acids effect on wound healing.
Physiological events in the initial inflammatory stage of cutaneous wound healing influence subsequent stages. Proinflammatory cytokines coordinate molecular and cellular processes during the inflammatory stage. Polyunsaturated fatty acids (PUFA) alter proinflammatory cytokine production, but how this phenomenon specifically influences wound healing is not clearly understood. In the present stu...
full textReview Article: The importance of Omega-3 fatty acids in fish on human health
Heart failure (HF) incidence increases worldwide and is affected by various risk factors such as coronary artery disease, hypertension, obesity, and diabetes. Dietary recommendations for patients with HF have generally focused on sodium restriction; however, different nutritional approaches are considered in patients with a high risk of malnutrition due to the diuretic drugs they use. Omega-3 f...
