to study the possibility that cephalosporins augment the nephrotoxicity of gentamicin , groups of rats were given four hourly subcutaneous doses of : gentamicin ( 5 mg/kg ) , gentamicin plus cephalothin ( 100 mg/kg ) , gentamicin plus cefazolin ( 20 mg/kg ) , gentamicin plus cefazolin ( 50 mg/kg ) , gentamicin plus cephaloridine ( 50 mg/kg ) , or saline diluent for 15 days .
