Abstract
Liver damage resulting from 4 h exposure to bromobenzene (BB) (146–957 ppm) and 1,2-dichlorobenzene (DCB) (245–739 ppm) as model toxicants was evaluated in rats. The modifications considered were the increases in serum glutamate dehydrogenase (GLDH) and sorbitol dehydrogenase (SDH) activities and the decreases in centrolobular liver-cell glucose-6-phosphatase (G6-Pase) staining intensity. A linear inverse relationship was established between the logarithmic values of blood enzyme activities and liver G6-Pase staining intensity. In addition, the levels of exposure to each test chemical were found to be linearly related to liver G6-Pase staining intensity and to the logarithmic values of blood enzyme activities.
