Antioxidant properties of ghrelin have been recently reported on various oxidative stresses in limited tissues. This study was set to examine the possible antioxidative effects of ghrelin in rat ovarian tissue. Twenty eight female adult Wistar rats were randomly allocated into control and treatment groups. Treatment group (n=14) received 2nmol of ghrelin as(More)
Purified oleuropein from olive leaf extract has been shown to have antioxidant effects in our recent studies. Thus, the aim of this study was to assess the antioxidant abilities of oleuropein in comparison with ranitidine in ethanol-induced gastric damages via evaluation of ulcer index inhibition, antioxidant enzyme activities, and lipid peroxidation level.(More)
This study was conducted to examine the efficacy of ghrelin in prevention of deleterious effects of heat stress in rat testicular tissue. Forty five adult male rats were scheduled for this study and were divided equally into three groups: heat-saline, heat-ghrelin and control-saline. The scrota of heated-designed rats were immersed once in water bath at 43(More)
The aim of the present study was to evaluate the antioxidant effects of betaine against oxidative stress and pathological changes mediated by cadmium in the testes of rats. The adult male Wistar rats were allocated into three experimental groups as follows: the cadmium group received cadmium chloride at the dosage of 2 mg/kg intraperitoneally thereafter,(More)
Ghrelin, the endogenous ligand for growth hormone secretagogue receptor, has been reported to prevent ischemia/reperfusion (I/R) injury in various tissues by its antioxidant activity. Therefore, this study was aimed to investigate the effect of ghrelin on sperm quality and antioxidant enzyme activity in a rat testicular ischemia/reperfusion injury model.(More)
Apoptosis and proliferation are the common and essential events of reproductive function and development in the ovary, especially during follicular growth and atresia or luteal regression. Therefore, this study was set to investigate the influence of ghrelin treatment on apoptosis and proliferation specific indices in the rat ovary. Twenty-eight adult(More)
Effect of improved diet on semen quality and scrotal circumference in the ram. ABSTRACT The aim of this investigation was to assess the effect of improved diet above maintenance requirement on reproductive parameters, including testicular size, semen volume, sperm concentration and viability. Twelve Bakhtiary rams were allocated to two groups of six animals(More)
The present study was designed to evaluate possible protective effects of purified histaminase from Lathyrus sativus L. seedling on the myocardial injuries upon isoprenaline-induced myocardial infarction in rats. In this regard, blood histamine concentration, creatine kinase-MB (CK-MB) activity, antioxidant status, and histopathological changes of the(More)
ABStrAct Ten, 4-to 6-week-old BALB/c mice were randomly assigned to either control (non-vitrified, n = 5) or treatment (vitrified, n = 5) groups. Ovaries in the vitrified group were frozen sequentially by immersion into two vitrification solutions VS1: 10% ethylene glycol (EG) + 10% DMSO in holding medium (TCM-199 + 20% FBS) and VS2: 20% EG + 20% DMSO in(More)
Ghrelin and oleuropein have recently been shown to bear beneficial effects against oxidative stress in our reports. The aim of this study was to evaluate the antioxidant abilities of ghrelin and oleuropein in a lipopolysaccharide (LPS)-induced nephrotoxicity model. The Sprague-Dawley male rats were divided into LPS, the ghrelin1 plus LPS (Ghr1+LPS), the(More)
