[Subacute (5 weeks) subcutaneous toxicity study of cefsulodin using 3-week-old juvenile beagle dogs].
A subacute (5-week) subcutaneous toxicity study of cefsulodin (CFS) was carried out using 9 3-week old juvenile Beagle dogs. The dogs were distributed to 3 groups, each of which was constituted of 3 animals. Dogs in group I, II and III were given physiological saline (control), 300 mg/kg of cefazolin (CEZ, control drug) and 300 mg/kg of CFS, respectively. All animals used survived for 35 days of administration period. The changes, considered to be drug-related were histopathological changes at the sites of injection, which consisted inflammatory cellular infiltration and hyperplasia of fibroblast in subcutaneous tissue of skin. In terms of severity, CFS was less irritating than CEZ. CFS-related changes were not observed in other tests.
