Abstract: Inhibitory effect of L aminaria japonica polysacchrides (L PS) on micronucleus rate induced by cyclophosphamide (CP) had been studied by mean of micronucleus test in mouse bonemarrow polychromatic erythrocyte (PCE) . Micronucleus rates of positive cont rol group (CP 40mg/ kg. bw) , and three L PS tested groups (L PS 500mg/ kg , 1000mg/ kg , 2000mg/ kg) was 28 ‰, 22 ‰, 12 ‰, 11 ‰, respectively. There were significant differences tested groups (1000mg/ kg , 2000mg/ kg) as compared with positive cont rol group. The results showed that L PS possessed inhibitory effect s on mutagenesis indued by cyclophamide.

Key words: L aminaria japonica polysaccharides, cyclophosphamide, micronucleus rates
