Objective:
To study the effects of BSO, GSH, Vit-C and DMPS on the nephrotoxicity of mercury.
Methods:
The rats in groups 1, 2 and 3 were sc injected with 0.75, 1.5 and 2.5 mg/kg HgCl2, respectively. Fourth group rats were ip injected with 0.5 mmol/kg BSO and 4h later sc administrated with 0.75 mg/kg HgCl2. The rats in groups 5, 6 and 7 were ip injected with 3 mmol/kg GSH, 4 mmol/kg Vit-C, 200 micromol/kg DMPS, respectively, and 2 h later sc administrated with 2.5 mg/kg HgCl2. Eighth group rats were sc injected with saline as a control. Mercury concentrations in the liver, renal cortex and urine, urinary NAG, ALP, LDH activities, protein and BUN contents were determined.
Results:
Urinary NAG, ALP activities, protein and BUN contents in the rats of BSO pretreatment group were significantly higher than that of 0.75 mg/kg HgCl2 alone group and control group. As compared with 2.5 mg/kg HgCl2 alone group, urinary NAG, ALP, LDH activities, urinary protein and BUN contents decreased significantly.
Conclusion:
BSO pretreatment could enhance the renal toxicity of mercury and GSH, Vit-C and DMPS pretreatment had antagonistic effects on nephrotoxicity of mercury.

Enhanced Elimination of Poison
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
