Effect of Factors Separated from the Venoms of Scorpion and Jelly Fish on Fertility in Immature Male Mice

El-Sawi, N.M. 2007. Effect of factors separated from the venoms of scorpion and jelly fish on fertility in immature male mice. J. Appl. Anim. Res., 32: 85-88. Bradykinin potentiating factors (BPF) from 2 sources, Egyptian scorpion (Leiurus quinquistriatus) and Jelly fish (Cassiopea andromeda) were injected intraperitoneally as a single dose (24 h). Amplification with bradykinin B2 receptor-specific primers, gave a single 739 bp product from cRNA. The amount of BK expression increased distinctly after injection of scorpion and jelly fish venom. Both factors induced an increase in the level of testosterone hormone and number of interstitial cells. The results suggested that these 2 extracts might be effective in improvement of the infertility patients.
