Cannabis Sativa is a multiuse herb in traditional medicine, its hydroalcoholic extract (10, 50, and 100 mg/kg) administered interaperitoneally for 14 consequent days to Wistar male rats resulted in significant decrease in progressive motility of sperm. Sperm count and seminiferous tubules diameter decreased significantly in comparison with control group. Also decrease in animal body weight in d...

Ascending aorta coarctation was produced by a minimally invasive technique in rabbits. Animal mortality was 5%. Morphometric and hemodynamic parameters were evaluated. A parabiotically isolated heart model was used to assess the hemodynamic parameters. Left ventricular weight/body weight ratio and muscle area showed clear evidence of hypertrophy when compared to control. The hemodynamic changes...

MEYER, J. H. AND W. A. HARGUS. Factors in@~t~~~ing food intake of rats fed low-fir&n rations. Am. J. Physiol. I g7(6) : I 350135** I g5g.-Rats fed low-protein rations increased food intake, weight gain and gain in lean body mass when forced to expend energy by low environmental temperature or exercise (swimming). Rats fed low-protein rations with a higher proportion of fat in their weight gain ...

this study was conducted to investigate direct and maternal effects on some economic traits in north iranian native fowls. traits considered were body weight at 1 day of age (bw1), body weight at 8 weeks of age (bw8), body weight at 12 weeks of age (bw12), egg number (en) during the first 12 weeks of laying period, egg weight at 1st day of laying (ew1), mean egg weight at 28th, 30th and 32nd we...

the kermani sheep is an important meat producing an animal in iran and its economic efficiency is mainly dependent on its growth and reproduction ability. inter-simple sequence repeat (issr) is the genome region between microsatellite loci. the aim of this study was to evaluate the association of two different issr markers with predicted breeding values (pbv) of body weight trait in kermani she...

Social stress resulting from dominant-subordinate relationships is associated with body weight loss and altered body composition in subordinate (SUB) male rats. Here, we extend these findings to determine whether stress-induced changes in energy homeostasis persist when the social stress is removed, and the animal is allowed to recover. We examined body weight (BW), body composition, and releva...

Uninfected animals can attempt to prevent parasitism in many ways. Behavioural avoidance of parasitized conspecifics, for instance, is documented several species. Interactions with conspecifics also, however, lead physiological changes uninfected animals, an effect that much less well studied, and consequently, understood. The way which exposure risk the physiology impacts those on animal fitne...
