abstract pollution is a world problem with serious consequences. heavy metals are an important group of these contaminants and enter aquatic ecosystems from anthropogenic and natural sources and animal health and systems are affected. in this study, the effect of lead exposure (3 mg/l concentration, 30 days) on activity of tissue enzymes, including acetyl cholinesterase, alanine aminotransferas...

Ethanol in the presence of disulfiram (N,N,N',N'-tetraethylthiuram disulfide, an inhibitor of aldehyde dehydrogenase) inhibited liver beta-alanine-oxoglutarate aminotransferase (beta-AlaAT I) activity yet activated tyrosine aminotransferase (TAT) in weanling rats in vivo. The effect on beta-AlaAT I was followed by the inhibitory expression of beta-AlaAT I mRNA. The beta-AlaAT I activity was red...

two hundred and twenty one-day male chicks (ross 308) were used in a completely randomized design with 5 treatments and four replicates each to investigate the effects of the different levels of 0.15, 0.3 and 0.6 percent rosemary extract along with nitrate (27.4 mg sodium nitrate/liter water) in drinking water on growth, some blood parameters and carcass characteristics of broiler chickens. no ...

Rat hepatocytes were incubated in monolayer culture in modified Leibovitz L-15 medium containing either 10% (v/v) newborn-calf serum or 0.2% (w/v) fatty-acid-poor bovine serum albumin. The addition of 100 nM-dexamethasone increased the activities of both phosphatidate phosphohydrolase and tyrosine aminotransferase by about 3.5-fold after 8h, and these activities continued to rise until at least...

Rice striped stem borer is a cosmopolitan pest that widely distributed in different regions of northen Iran and spraying with diazinon is the most common procedure to control this pest. We evaluated comparative physiological effects of diazinon spraying on the three populations of Chilo suppresalis collected from Gourabzarmikh (Go), Sheikhmahale (Sh) and Rasht (Ra) in Iran. The determination of...

On starch-gel or polyacrylamide-gel electrophoresis of human serum, a supernumerary zone of aspartate aminotransferase activity may be demonstrated, migrating with the slow alpha(2) protein zone. This appearance is due only to cationic aspartate aminotransferase, bound by alpha(2)-macroglobulin. The binding is strongly potentiated by dilute borate buffers.

  The aims of the present study were to determine the best time for egg stripping after ovulation and to study oocyte over-ripening in the Caspian brown trout (Salmo trutta caspius). Eggs were retained in the female abdominal cavity for 40 days post ovulation (DPO). Partial volumes of eggs stripped from 10 individually identified females at 10 days intervals and fertilized with a pool of semen ...
