genetic parameters and trends for milk and fat yields as well as for fat percentage were estimated from 35,438 milk production records (305d, 2x) of 17,971 holstein dairy cattle in 133 herds during the period of 1990-2003 in khorasan province. variance components were estimated using restricted maximum likelihood statistical method applying univariate and repeatability animal models. for the un...

one way to confront chemical warfare in order to reduce their harmful effects, is to use the body's defense mechanisms. in order to do so firstly mustard gas (hd) was injected in an animal model in the form of an immunogen and the induced humoral immune response was investigated by two different immunological methods such as the ouchterlony test and a new liquid phase fluoroimmunoassay. 7l...

objective: to determine the preventive effects of local administration of simvastatin for postoperative intra-abdominal adhesion formation in animal model of rat . methods: in this experimental study, 32 wistar albino rats as the animal model of intra-abdominal adhesion formation were included. adhesions were induced in all the animals via abrasion of the peritoneal and intestinal surface durin...

objective(s) two new adjuvants from natural animal lipids (g2) and bacterial polysaccharide extracts (pc) were previously prepared by our group and showed a reduction in tracheal responsiveness. the aim of this study was to evaluate the preventive effect of recently introduced natural products (g2 and pc) on the development of asthma. materials and methods asthma was induced using a standard me...

While significant medical breakthroughs have been achieved through using animal models, our experience shows that often there is surplus material remaining that is frequently never revisited but could be put to good use by other scientists. Recognising that most scientists are willing to share this material on a collaborative basis, it makes economic, ethical, and academic sense to explore the ...

basic research on the autoimmune disease multiple sclerosis has been performed mainly on its animal model namely experimental allergic encephalomyelitis. there are many different approaches established to get this model. despite the existence of many references in literature in this regard, we have been faced with many difficulties generating the model suitable for studying different therapies....
