background: the purpose of this comparative study was to detect superoxide dismutase (sod) activities in fasciola hepatica, f. gigantica parasites, infected and healthy liver tissues in order to determine of species effects and liver infection on sods activity level. methods: fasciola spp. parasites and sheep liver tissues (healthy and infected liver tissues), 10 samples for each, were collecte...

The present study was carried out in 2011 to measure concentration of heavy metals chromium and tin in liver and muscle tissue of Liza aurata (golden grey mullet) in estuaries of the rivers Babolroud, Tajan and Gorganroud. Accordingly, after sampling the target are asandisolating muscle (18samples) and liver (18samples) tissues, they were digested and analyzed using Graphite Furnace Atomic Abso...

Background: Studies have shown that organophosphorus pesticides such as malathion induces oxidative stress injury and tissue damage.  Objectives: This research aimed to determine the effects of the hydroalcoholic extracts of Satureja avromanica (SA) on the liver function of malathion-poisoned animals. Methods: Twenty-eight rats were divided into four groups of the control, SA (20 mg/kg), mala...

Background: Zinc oxide (ZnO) nanoparticles are used for various industrial and domestic purposes and its release into the environment leads to the adverse effects among humans. This study aimed to evaluate the effect of rat exposure to ZnO nanoparticles on the histopathology of the liver and pancreas tissues, and serum oxidative stress parameters. Methods: Eighty female adult Wistar rats were ...

Variations in phosphatidate phosphohydrolase (PAP) activity and triacylglycerol concentration were measured in pregnant and hormone-treated non-pregnant female rats. PAP activity in adipose tissue was elevated by 61% during pregnancy. The increase in the enzyme activity was paralleled with a rise in serum triacylglycerol concentration (44%). Estradiol injecting into non-pregnant rats increased ...

Tissue metal accumulations (gills, liver, kidney and muscle) in Persian sturgeon (Acipenser persicus) were compared folowing exposure to sublethal levels of waterborne Cd (50, 400 and 1000 μg•L-1) after periods of 1, 2, 4 and 14 days. The obtained results indicate that at the end of 4 and 14 days of exposure, total tissue cadmium concentration followed the pattern: liver > gill > kidney > muscl...
