Abstract: OBJECTIVE: To study acute oral toxicity and mutagenicity of lyophilizing hirudin powder. METHODS: Lyophilizing hirudin powder(50 AT-U/g)was given orally to mice to determine its acute oral toxicity, and mutagenicity was studied using Ames test, micronucleus test and sperm shape abnormality test. RESULTS: The oral LD50 of lyophilizing hirudin power in mice was more than 10.0 g/kg. No increase in the number of revertant colonies was found in the Ames test with and without S9 mixture. The micronucleus rates and sperm abnormality rates in all doses were not significantly different from the negative control. CONCLUSION: Lyophilizing hirudin powder showed no acute oral toxicity and mutagenicity.

Key words: lyophilizing hirudin powder, acute toxicity, mutagenicity
