Renal Lysosomal Functions on Exposure to Scatophagus argus Venom in Experimental Mice.
ABSTRACT Scatophagus argus venom was extracted by homogenization and centrifugation. The lysosome-enriched fraction of mice kidney was isolated by differential centrifugation. To study the effect of S. argus venom on lysosomal membrane stability, acid phosphatase and cathepsin D, the two marker enzymes for lysosome, were assayed. In the renal lysosomal enriched fraction incubated with different concentrations of venom and at various time intervals, in vivo and in vitro studies were done. Studies reveal that with increasing concentration of venom and time, the activity of the enzymes increased, which showed that the membrane integrities decreased for both in vitro and in vivo studies. The activity of the enzymes acid phosphatase and cathepsin D showed a dose-dependent relationship with S. argus venom.
