Anti-inflammatory role of obestatin in autoimmune myocarditis.

Obestatin is a popular endogeneous peptide, known to have an autoimmune regulatory effect on energy metabolism and the gastrointestinal system. Studies regarding the anti-inflammatory effects of obestatin are scarce. The aim of this study was to show the anti-inflammatory effect of obestatin in an experimental model of autoimmune myocarditis in rats.

Hepatoprotective effect of ghrelin on carbon tetrachloride-induced acute liver injury in rats.

Background & Aims: Recent studies have revealed that ghrelin may be an antioxidant and antiinflammatory agent. Oxidative stress are considered to play a prominent causative role in the development of various hepatic disorders. We investigated whether ghrelin plays a protective role against carbon tetrachloride (CCl(4))-induced acute liver injury in rats.

Protective role of ghrelin against carbon tetrachloride (CCl₄)-induced coagulation disturbances in rats.

Recent data indicate that ghrelin has protective effects in different organs and cell types including the pancreas, heart, and gastrointestinal tract. The purpose of this study was to determine whether ghrelin plays a protective role against CCl₄-induced coagulation disturbances in rats. Fourty male Sprague-Dawley rats were equally divided into four groups including group 1 (1 ml physiological saline s.

Chlorpyrifos induces cardiac dysfunction in rabbits.

This study was carried out to evaluate the effects of organophosphate (OP) insecticide chlorpyrifos on cardiac morphology and function in rabbits using echocardiography. Twenty New Zealand male rabbits were divided equally into four groups. Rabbits were exposed to chlorpyrifos in drinking water at concentrations of 0, 125, 250 or 375 ppm for 90 days.

Echocardiographic variables in healthy guineapigs anaesthetized with ketamine-xylazine.

Echocardiographic parameters were recorded, measured and statistically analysed on a population of 12 male Hartley albino guineapigs under ketamine-xylazine anaesthesia. Additionally, the effect of body weight on these parameters and the correlation between the parameters were assessed. The mean values of left ventricular internal diameter in end diastole (LVIDD), left ventricular internal diameter in end systole (LVIDS), interventricular septum thickness in diastole (IVSD), interventricular septum thickness in systole (IVSS), left ventricular posterior wall thickness in diastole (LVPWD), left ventricular posterior wall thickness in systole (LVPWS), left atrial diameter (LA), aortic diameter (AO), left ventricular fractional shortening (FS) and left ventricular ejection fraction (EF) were measured or calculated as 6.
