Evaluation of carcinogenic responses in the Eker rat following short-term exposure to selected nephrotoxins and carcinogens.

This study examined the response of the Eker rat to nephrotoxic compounds and to genotoxic nonrenal carcinogens. Groups of male Eker rats received either no treatment; a vehicle treatment; treatment with a noncarcinogenic nephrotoxin (aluminum nitrilotriacetate, 2 mg/kg/day of aluminum, intraperitoneally, 3 days per week or cyclosporine A, 30 mg/kg/day, orally by gavage, 7 days/week); or treatment with a genotoxic nonrenal carcinogen (furan, 8 mg/kg/day, orally by gavage, 5 days/week or 2,4-diaminotoluene, 6.5 mg/kg/day, orally by gavage, 7 days/week or 2-nitropropane, 89 mg/kg/day, orally by gavage, 3 days/week).
