Knot, Harm J., Karen M. Lounsbury, Joseph E. Brayden, and Mark T. Nelson. Gender differences in coronary artery diameter reflect changes in both endothelial Ca21 and ecNOS activity. Am. J. Physiol. 276 (Heart Circ.

Background and Objectives: Previous studies have shown the antinociceptive effect of morphine in animal models, but the specific anti-pain consequence of the abuse drug in female animals is unclear. The present research showed the morphine antinociception in female Wistar rats using formalin test. Materials and Methods: Subjects were 40 female Wistar rats purchased from Pasteur Institute of Ir...

Ten female lambs of 7-month-old were divided into two equal groups and raised under a helminth-free conditions. Animals in group 1 were immunized two times by whole gut homogenate (WGH) of Haemonchus contortus emulsified in Freund’s adjuvant. In group 2 (control), animals were injected by phosphate buffered saline emulsified in the same adjuvant. Animals were challenged by 10000 third-stage lar...

Previous research has demonstrated that in households where the male partner is more dominant, there is convergence in male and female attitudes towards animals, whereas if the female partner is empowered they exhibit greater empathy towards animals than the male partner. We tested this theory of 'female empowered empathy' internationally in a survey of female and male students' attitudes towar...

Elevation of nitric oxide (NO) release from the vascular endothelium may contribute to some of the gender-associated differences in coronary artery function. The mechanisms by which gender affects NO release from the endothelium of coronary arteries are not known. In this study, endothelial function was examined in pressurized coronary arteries from female and male rats. Diameter and endothelia...

A bioassay for possible carcinogenicity of technical-grade hexachloroethane was conducted using Osborne-Mendel rats and B6C3F1 mice. Hexachloroethane in corn oil was administered by gavage, at either of two dosages, to groups of 50 male and 50 female animals of each species. The chemical was administered 5 days a week, cyclically for 44 of 78 weeks in rats and continuously for 78 weeks in mice,...

Chlamydia trachomatis is a major cause of sexually transmitted diseases worldwide. There is currently no vaccine to protect against chlamydial infection of the female reproductive tract. Vaccine development has predominantly utilised the murine model; however, infection of female guinea pigs with Chlamydia caviae more closely resembles chlamydial infection of the human female reproductive tract...

The objective of this research was to evaluate the interference of ethanol consumption by female rats with cytokines involved in the sepsis process and its correlation with mortality, the main outcome of sepsis. Female Wistar rats in estrus phase were evaluated in three experiments. Experiment 1 (n=40) was performed to determine survival rates. Experiment 2 (n=69) was designed for biochemical a...
