  • Title: Nephrotoxicity of bromobenzene in mice.
    Author: Rush GF, Kuo CH, Hook JB.
    Journal: Toxicol Lett; 1984 Jan; 20(1):23-32. PubMed ID: 6695393.
    Abstract:
    I.p. administration of bromobenzene to male mice at doses ranging from 0 to 9.4 mmol/kg resulted in a dose-dependent increase in blood urea nitrogen (BUN) and serum glutamic-pyruvic transaminase (SGPT) activity and a decrease in renal cortical accumulation of para-aminohippurate (PAH) and tetraethylammonium (TEA). Induction of renal and hepatic mixed-function oxidases by beta-naphthoflavone (BNF) did not result in any alterations in the hepatotoxic or nephrotoxic response to bromobenzene. Renal and hepatic non-protein sulfhydryl (NPSH) concentrations were decreased significantly 1 h after administration of bromobenzene (7.5 mmol/kg) and were maximally depleted in both organs to 18% of control after 7 h. Depletion of renal NPSH by bromobenzene was dose-dependent up to 9.4 mmol/kg. Treatment of mice with diethyl maleate (DEM) (0.6 ml/kg) 60 min prior to bromobenzene administration resulted in greater hepatotoxicity, evidenced by increased SGPT, while renal toxicity was unchanged. These data demonstrate that large doses of bromobenzene produce functional alterations in the kidney.
