Ghrelin has recently been reported to exert beneficial effects on various oxidative stresses as a result of its antioxidant properties. Therefore, we designed this study to explore the probable antioxidative effects of this peptide in the testis. Twenty-eight male adult Wistar rats were divided into equal control and treatment groups. In the treatment(More)
This study was set to investigate whether the adverse effects of heat on spermatozoa and subsequent foetuses could be prevented by long-term zinc administration. The scrotums of animals were immersed in water at either 43 degrees C (heat group) or 23 degrees C (control group). Half of the heat and control mice were given 10 mg kg(-1) zinc every other day(More)
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)
The aim of our investigation was to examine the influence of chronic administration of ghrelin on the rat ovarian state. Morphometrical and intracellular changes in the ovary of 35-d female Wistar rats after sc injection of 1 nmol of ghrelin for 10 consecutive days were studied. Control animals (n=10) were injected with normal saline using similar method.(More)
Ghrelin has recently been shown to improve renal function in rat with acute renal failure. In this setting, the protective effects have been suggested to be due to its antioxidant properties. Thus, the aim of this study was to measure the antioxidant abilities of this hormone via enzymatic and lipid peroxidation analyses. Wistar rats were divided into two(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)
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)
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 and were fed during a 12-week experiment period with different diets which were(More)
The purpose of this study was to evaluate the development of vitrified-warmed mouse blastocysts following a period of Vitamin A administration. Four to six weeks old BALB/c mice were given an intraperitoneal injection of either 0.1 ml paraffin oil alone (control, Con) or paraffin oil containing 250IU of Vitamin A (experiment, Exp). Ten days later the mice(More)
