In vivo blastocyst production and collection using superovulation and intrauterine insemination was established in albino Syrian hamsters. Twenty female albino hamsters were injected pregnant mare serum gonadotropin (PMSG, 25 IU) in non-breeding season and 48 h or 56 h later, 25 IU of human chorionic gonadotropin (hCG) were injected. Both groups were divided into two subgroups of natural mating...

BACKGROUND The Ruta graveolens L. is currently used by the Jordanian population systemically for its antispasmodic, diuretic, sedative, and analgesic effects and externally for its antirheumatic effect. OBJECTIVE To study plant effects on the reproductive system and fertility using adult male albino rats with special emphasis on the aggressive behavior and sex behavior. The aqueous extracts o...

PURPOSE Female patients show better recovery after brain injury and lower incidence of vascular diseases before menopause. The aim of this study was to test the protective effect of female sexual hormones against photostress-induced photoreceptor apoptosis. METHODS Five week old male albino Sprague-Dawley rats were injected intraperitoneally with progesterone (60 mg/kg body weight) for 4 days...

Alloparenting, a behavior in which individuals other than the actual parents act in a parental role, is seen in many mammals, including house mice. In wild house mice, alloparental care is only seen when familiar sibling females simultaneously immigrate to a male's territory, so in the laboratory, when a pair of unfamiliar female wild mice are mated with a male, alloparenting does not occur bec...

You are studying the mode of inheritance of eye color in flies. You have isolated four true-breeding mutant strains with green eyes . In contrast, wild-type flies have red eyes . In your Strains box in StarGenetics you will find 1) homozygous mutant male and female flies for each mutant strain and 2) homozygous wild-type male and female flies. In each of the four mutant strains, the mode of inh...

Steroid hormones, especially estradiol, facilitate reproductive behaviors in male and female rodents and birds. In green anole lizards estradiol facilitates receptivity in females but, unlike in some other species, is not the activating hormone for courtship and copulatory behavior in males. Instead, testicular androgens directly facilitate male courtship and copulation. Yet, activity of the es...

objective(s):one cause of cigarette smoking is oxidative stress that may alter the cellular antioxidant defense system, induce apoptosis in lung tissue, inflammation and damage in liver, lung, and kidney. it has been shown that chinese green tea (cgt) (lung chen tea) has higher antioxidant property than black tea. in this paper, we will explore the preventive effect of cgt on cigarette smoke-in...

Renal ischemia-reperfusion (I/R) is the major cause of acute renal failure. Renal I/R have distant effects on other organs, especially the heart. The purpose of this study was to investigate cardiac lesion following bilateral renal ischemia (50 minutes) and reperfusion (48 hours) in adult rats, to test sex differences in the development of cardiac lesions after acute renal I/R and to investigat...

The aim of present work is to investigate the effects of green tea on some blood parameters of male albino rats with cadmium toxicity. 24Male albino rats were divided into 4groups, 6 normal rats and 18 cadmium intoxicated rats. Group 1 without treatment (controls), group 2 treated with cadmium, group 3 and group 4 treated with cadmium and green tea. Group (1) was fed on a standard diet as a con...

Tnis(p-aminophenyl)carbonium pamoate (2 lots) was administered as drug-diet for an 18-month period to male and female albino rats (Holtzman source) . Both lots of compound were prepared from the chloride salt, one from an approximately 98.6 % pure sample, and the other from a highly purified and apparently homogenous sample. There was a marked increase in total tumor incidence in the treated fe...
