title: Effect of omega-3 fatty acids on haemostatic functions in urocortin-treated obese rats.
abstract: Urocortin 1 (UCN1) decreases food intake. We investigated the effects of UCN1 and omega-3 fatty acids (FA) on metabolic and coagulation parameters in high fat diet (HFD)-fed rats. Fifty male Sprague Dawley rats were divided into five groups; control, HFD, HFD with omega-3 FA, HFD with UCN1, and HFD with UCN1 and omega-3 FA. Food intake, body weight (BW), body mass index (BMI), Lee index, glucose, insulin, HOMA-IR, triglycerides, cholesterol, low (LDL) and high (HDL) density lipoproteins, fibrinogen, plasminogen activator inhibitor 1 (PAI-1), fibrin degradation product (FDP), clotting time, bleeding time, prothrombin time (PT), activated partial thromboplastin time (aPTT), and platelet aggregation were measured. Food intake, BW, BMI, Lee index, glucose, insulin, HOMA-IR, triglycerides, cholesterol, LDL, fibrinogen, platelet aggregation, PAI-1, and FDP increased while bleeding and clotting times, PT, and aPTT decreased in HFD rats. UCN1 decreased food intake, BW, BMI, Lee index, bleeding and clotting times, PT, and aPTT and increased fibrinogen, PAI-1, FDP, and platelet aggregation in HFD rats. Omega-3 FA decreased food intake, BW, BMI, Lee index, platelet aggregation, glucose, insulin, HOMA-IR, triglycerides, and increased HDL and bleeding time in HFD rats. We concluded that UCN1 worsens the hypercoagulable state in HFD rats while omega-3 FA improve the insulin resistance and decrease the platelet aggregation in those rats.
