Carcinomas have been reported in animals following the injection of asbestos, but the production of carcinomas by inhaled asbestos is les...
متن کاملToxicological, pathological, and teratological studies in animals with cephradine.
Cephradine, a semisynthetic cephalosporin antibiotic, has a low order of oral and parenteral toxicity in animals. The oral LD(50) in mice and rats ranged from 5 to >8 g/kg, and the intraperitoneal LD(50) values in mice and rats were 0.7 to 1.5 g/kg and 4.0 g/kg, respectively. The intravenous LD(50) in mice ranged from 3.0 to 3.8 g/kg. In anesthetized dogs, intravenous doses of cephradine (40 an...
متن کاملThe pathological changes in peripheral organs of scrapie-infected animals.
