Background: The aim of this study was to investigate the effects of STZ (Streptozotocin) and Rambutan peel extract (RPE) on serum visfatin and cardiac response in experimental Type 2 diabetic rats. Methods: In this study, 64 adult male Wistar albino rats, aged between 8-10 weeks, were used. 8 groups were randomly selected, each containing 8 rats as Control (C), R100 (RPE 100 mg/kg group given with oral gavage route of administration (OGRA), R200 (RPE 200 mg/kg group given with OGRA), R300 (RPE 300 mg/kg group given with OGRA); Diabetes Control (DC): STZ 50 mg/kg i.p administered group, DR100 (D+100 mg/kg JPE), DR200 (D+200 mg/kg JPE), DR300 (D+300 mg/kg JPE). 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 subjects on days 0 and 21 of the study. Visfatin and cTnI levels in the serum samples were measured and evaluated by ELISA method. Result: While the increase in mean serum visfatin and cTnI levels in diabetic groups was seen mostly in DC groups, the most significant decrease in mean serum visfatin level due to the addition of RPE was determined in DR100 groups (p<0.01). As a result, it was concluded that the administration of 100 mg/kg RPE in rats had no adverse effects. It was concluded that RPE, which has a cardioprotective effect by regulating the visfatin response that plays a role in the development of diabetes, may be useful in supporting the impaired cardiovascular system function that occurs in diabetes.

This study was conducted to investigate adipokine [Apelin and brain-derived neurotrophic factor (BDNF)] and cardiac troponin (cTnI) response that emerged after adding an essential oil mixture (EOM) (Eucalytus glabutus labii, Thymus vulgaris, Cymbopogon nardus, and Syzygium aromaticum) at different rates to the drinking water of broilers in which thyroid dysfunction (hypo-and hyperthyroidism) had been experimentally induced. In the present study, 150 1-day-old Ross-308 male broiler chicks were used. They were divided into five groups, each with 30 animals. The groups were designed to include five subgroups: control (C), hypothyroid, hypothyroid + 250 ppm EOM, hyperthyroid, and hyperthyroid + 250 ppm EOM, with six animals in each group. At the end of the experiment, Apelin, p-BDNF, cTnI, T3, T4, and thyroid-stimulating hormone (TSH) levels were investigated in blood serum samples obtained by cervical dislocation from four randomly selected animals from each subgroup, making 100 animals in total. It was found that EOM administration resulted in a dose-dependent increase in p-BDNF and apelin levels, and a decrease in T4 levels in the experimentally induced hypo-and hyper-thyroidism groups, but did not affect T3 and cTnI levels. Conversely, an increase in TSH level was observed in the hypothyroidism groups, whereas a decrease was observed in groups with hyperthyroidism. This study is the first to examine adipokine (Apelin and BDNF) and cTnI response to EOM administration in thyroid dysfunction.
