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...

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...

Background: An evaluation of the effect Moringa oleifera methanol leaves extracts on Sodium/Potassium ATPase xin streptozotocin-induced experimental diabetic albino male rats’ model.Methods: Q ualitative phytochemical analysis was carried out M. usingacceptable chemical methods. The LD50 plant extract conducted and non-lethal at 5000mg/kg. Thirty, rats weighing 120g – 180g were arranged into fi...

High environmental hydrogen peroxide (H2O2) has been demonstrated to be toxic for fish. However, the response mechanism of fish chronic H2O2 exposure is not yet well understood. Therefore, this study aimed investigate alteration in ion transport gills and analyzed potential after exposure. The common carps were exposed 0, 0.25, 0.50, 1.00 mM 14 days. histopathological evaluation results indicat...

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 ...
