Results: a In the negative control group, spontaneous chromosome aberration and micronucleus rated the mice's were very low; in the positive control group, chromosome aberration and micronucleus rate of the mice's were highest. b Before cyclophosphamide intoxation, when the four kinds of vegetables and hilts juice were preventively irrigated into the mice's stomachs respectively, the chromosome aberration and micronucleus rate in the negative control group were lower than these in the positive control group (P.05); but after intoxation, when the four kinds of vegetables and fruits juice were therapeutically irrigated into the mice's stomachs respectively, the chromosome aberration and micronucleus rate were similar with the result above mentioned . c Acing the four kinds of vegetables and fruits, sea-buckthorn lad the best preventive and curative effects.
