Objective-Ovarian torsion must be diagnosed and treated as much early as possible. The aim of the present study was to investigate effects of interaperitoneal administration of curcumin on ischemia-reperfusion injury in ovaries. Design- Experimental Study Animals- Twent-four healthy female Wistar rats Procedures- Twent-four healthy female Wistar rats weighing approximately 260...

Background: The aim of this study was to evaluate protective effects of melatonin on uterus and fallopian tube in female mice under treatment with nicotine. Materials and Methods: Adult Female mice were divided into four groups. Group A: control animals received normal saline, group B: were injected with nicotine 40 μg/kg. Group C:were injected with melatonin, 10 μg/ night. Group D:were injecte...

transgenic (tg) mice are very important models of disease, and have been introduced to biological studies since 1982. they are used for understanding the pathobiology of different diseases, finding targets for pharmacological manipulations, and for the evaluation of efficacy and toxicity of medicines in preclinical studies. many different types of tg mice are available as models for human disea...

Studies on white outbred 3,54-month-old male rats showed that stress caused by chronic 2-month social isolation has a negative impact reproductive function. A effect of long-term the sexual behavior was revealed: statistically significant increase in latent period until first emotional approach to female, decrease total time approaches, anogenital sniffing female partner, and number allogroomin...

Case Description- Five lions (one female and 4 male) were presented for diagnostic andsurgical treatment (wound management, castration and radiography). Immobilization oranesthesia was necessary to complete the procedure.Treatment and Outcome - Immobilization was induced using intramuscular injection ofvarious drug combinations (xylazine, diazepam or midazolam in combination withketamine). Inha...

A bioassay for the possible carcinogenicity of 2-nitro-p-phenylenediamine was conducted using Fischer 344 rats and B6C3F1 mice. 2-Nitro-p-phenylenediamine was administered in the feed, at either of two concentrations, to groups of 50 male and 50 female animals of each species. Twenty animals of each sex and species were placed on test as controls. The high and low dietary concentrations of 2-ni...

A bioassay of p-phenylenediamine dihydrochloride for possible carcinogenicity was conducted using Fischer 344 rats and B6C3F1 mice. p-Phenylenediamine dihydrochloride was administered in the feed, at either of two concentrations, to groups of 50 male and 50 female animals of each species. The high and low concentrations of p-phenylenediamine dihydrochloride were, respectively, 1,250 and 625 ppm...

The effects of host age and sex on susceptibility to Strongyloides venezuelensis in Wistar rats were examined by counting larvae recovered from the lungs of animals 3 days after infection. The susceptibility of female rats to S. venezuelensis rapidly decreased with age and elevated estrogen. Resistance in female rats inoculated at 6 and 10 weeks of age was nine and twenty-fold higher, respectiv...

Oral progestogens for contraception (8) have become a feature of our culture, exposing a significant proportion of the female population to exogenous hormonal agents for protracted periods. Despite their importance, there is a paucity of published data on the effects of these agents on carcinogenesis in laboratory animals. For this reason, we are recording the results of an in vestigation of En...

The gene virilizer (vir) is needed for dosage compensation and sex determination in females and for an unknown vital function in both sexes. In genetic mosaics, XX somatic cells mutant for vir differentiate male structures. One allele, vir2f, is lethal for XX, but not for XY animals. This female-specific lethality can be rescued by constitutive expression of Sxl or by mutations in msl (male-spe...
