Thirty six Wistar albino rats with implant induced endometriosis were randomly divided into six groups of six animals each. The rats in the first group received nothing and were euthanized at day 21. In the second group, rats received nothing and were euthanized at day 36. The third group received atorvastatin (ATV; 5 mg kg-1 per day, orally) until 21 days from induction of endometri...
The potential roles of growth hormone (GH) and insulin-like growth factor I (IGF-I) in seawater (SW) acclimation of juvenile Atlantic salmon (Salmo salar) were examined. Compared to controls, fish in 12 ppt seawater given one or three injections (2-6 days) of GH (ovine, 0.2 microgram.g-1) or IGF-I (recombinant bovine, 0.05-0.2 microgram.g-1) had significantly greater salinity tolerance as judge...

Over 200 rat eyes were enucleated for this study. The youngest rats were 21 days and the oldest 1,000 days old. All specimens were removed with as little trauma as possible and trimmed of adventitial tissue with small scissors and for ceps. Measurements were made with a small caliper having a micrometer adjust ment before the eyes were completely fixed, with the exception of the 1,000-day gro...
In this study was investigated histipathological effects of Cd and As on liver of Aphanius sophiae. For this reason, 350 specimens were collected on 2011 from the Shoor River. For saltwater and separately freshwater treatment were designed seven treatments including the concentrations of 5, 10 and 20 for As 5, 10 and 20 for Cd and a control treatment in 30- L aquaria with three replicates.
