objective: the urinary system of euryhaline fish, as well as the gills, is involved in ion regulation through the production of dilute urine in freshwater and isotonic urine in seawater. the low osmolality of the urine originates from an active reabsorption of ions by ionocytes or mitochondria rich-cells (mrcs) present in certain parts of the urinary system. mitochondria rich-cells possess a hi...

this study was carried out to determine the appropriate size of caspian trout ( salmo caspius kessler, 1877) juveniles for releasing into the rivers that enter south of the caspian sea for stock enhancement, or possibility of cage culture in the caspian sea. a total of 1611 specimens in 4 weight groups of 5, 10, 15 and 20g were exposed to 3 salinity trials which include caspian sea water (11- 1...

background: this study was aimed to assess the effects of angiotensin ii (ang ii) supplementation to the in vitro maturation (ivm) and in vitro culture (ivc) media of vitrified-warmed ovine oocytes on their developmental competence and expression of na+/k+/atpase in resulting embryos. methods: the slaughterhouse-derived immature oocytes (n=1069) were randomly distributed into four experimental ...

Carbosulfan (2,3-dihydro-2,2dimethyl-7-benzofuronyl [(dibutyl amino) thio] methyl] a carbamate insecticide and acaricide was administered orally at an effective dose of 48 mg/kg/day to albino mice for 5, 10, 20 and 30 days .Control mice received similar quantities of olive oil. Daily body weights were recorded and mice were sacrificed after 24 hours after the terminal exposure. The histologic e...

influence of folic acid on the cns is still unclear. folate has a neuroprotective effect, while on the other hand excess folate can exacerbate seizures in epileptics. the aim of the present study was to examine the effect of subchronic administration of folic acid on behavioural and electroencephalographic (eeg) characteristics of dl homocysteine thiolactone induced seizures in adult rats. t...
