Effect of Moringa oleifera Oil Extract on Adipokine (Apelin, Visfatin and Nesfatin-1) and Cardiac (cTnI) Response in Streptozotocin-induced Rats

Background: The aim of this study was to investigate the effects of Moringa oleifera extract (MOE) added to the diets at different amounts on Adipokine (apelin, visfatin and nesfatin-1) and Cardiac (cardiac troponin I (cTnI)) Response in Streptozotocin (STZ)-induced Type 1 diabetic rats. Methods: In this study, 64 adult male Wistar albino rats, aged between 8-10 weeks, were used. Eight (8) groups were created, with 8 rats in each group: Control (C), M100 (MOE 100 mg/kg group given with oral gavage route of administration (OGRA), M200 (MOE 200 mg/kg group given with OGRA), M300 (MOE 300 mg/kg group given with OGRA); STZ 55 mg/kg i.p administered group, Diabetic control group (DC), DM100 (D+100 mg/kg MOE), DM200 (D+200 mg/kg MOE), DM300 (D)+300 mg/kg MOE). The study lasted a total of 31 days, including adaptation (7 days), induction of diabetes (3 days) and trial period (21 days). Blood samples were taken from the tail vein (Vena caudalis) of all subMects on days 0 and 21 of the study. Apelin, visfatin, nesfatin-1 and cTnI levels in the serum samples were measured by ELISA method. Result: In the present study, the most significant increase in mean serum apelin, visfatin, nesfatin-1 and cTnI levels in diabetes groups was observed in DC groups, while the most significant decrease due to MOE addition was observed in DM200 groups (p<0.01). As a result, it was concluded that MOE may be safe and beneficial when administered at a dose of 200 mg/kg in rats with STZ-induced diabetes.
