Abstract

Pituitary glands homogenate of the cat fish ,S. schall induced sexual maturation of immature males and females Wistar rat (Ratus nervicus. the homogenate administrated intra peritoneal for 6 weeks by 0.26g/ml and0.52g/ml for treated animals and saline solution(4%)for control group. The PGH of S. schall resulted in significant effects presented by changes in gonads weights as well as anatomical and histological progression . The concentration levels of sex hormones(testosterone& progesterone)in serum of rats using EISA, DAS EISA plate reader used confirmed the positive effects. However, the effects require specific duration to exposed. these results relieved strong resemblance related to phylogeny relationship of vertebrates.
