[Hepatotoxicity of cyclophosphamide in the rat after prolonged treatment: a histomorphological study]

The AA. have examined the toxic effects in rats liver caused by cyclophosphamide (12 mg/kg) chronic administration for 12 months. The toxicity for the liver is moderate and the lesions are not specific. The lesion are various histologic changes, lymphomonocytic infiltration of the peri-portal space, periportal fibrosis and interstitial haemorrhages. Similar lesions with lesser recurrence are also in not treated rats.
