Experiments were carried out in vivo by injecting Tityus serrulatus crude venom in rats followed by biological assays on the isolated guinea-pig ileum, to show the effects of scorpion venom on kallikrein-kinin system. Our results showed effects such as significant decrease of total kinin rate and a decrease of Zn<img SRC="image2229.gif"> , Na<img SRC="image2227.gif"> , Cl<img SRC="image2228.gif"> and K<img SRC="image2227.gif"> ions in rat urine 24 and 48 hours after the injection of Tityus serrulatus crude venom.
