| Abstract |
|
This study was designed to investigate the effects of varying concentrations of $CdCl_2$ on the enzyme activities such as LDH and SOD related with the accumulations of cadmium(Cd) in liver and kidney of BALB/c mice. 1. Cd accumulations in liver and kidey were increased in a dose dependent fashion. And also, this pattern was more conspicuous in kidney than that in liver. 2. LDH activities of liver and kidney were increased in a dose dependent fashion except for that of liver in 200 ppm Cd group which was similar to that of 25 ppm Cd group. 3. SOD activities of Cd exposed liver and kidney in Cd-fed mice similar to those of controls except for elevation of SOD activity of liver in 25 ppm Cd group. The results of this study suggest that the activities of various enzymes can be modulated by Cd intoxication.
