[The protective effects of diallyl sulfide (DAS) on benzene-induced leukopenia in mice].

Objective: To study the protective effects of diallyl sulfide (DAS) on leukopenia induced by benzene. Methods: 90 Healthy male ICR mice, adaptive feeding 5 days later, 15 were randomly divided into blank control group、model group、low、middle、high dose DAS intervention groups and DAS control group. Mice in intervention groups and DAS control group were orally given DAS at 40, 80, 160, 160 mg/kg·bw, while mice in the other two groups received an equal volume of corn oil. After 2 hours, model group and the other three intervention groups were given benzene, corn oil suspension (1.3 g/kg·bw) , the two control groups treated with the same volume of corn oil, Benzene and DAS are dissolved in corn oil. one time for each day. 4 weeks later, Anesthesia at 14/29, make blood routine examination and count organ index and observe pathological examinations of spleen and thymus. Results: On day 14, the counts of peripheral blood white blood cells (WBC) , lymphocytes, monocytes in the model group decreased to 68.99%, 71.72%, 53.19% (P<0.05) ; On day 29, the counts of peripheral blood lymphocytes, monocytes, neutrophils in the model group decreased to 83.00%, 81.03%, 89.37%, 20.84%, 19.25% (P<0.05) ; spleen weight, spleen index, white pulp area ratio of spleen, thymus weight, thymus index, thymic cortex area ratio of mice in the model group decreased (P<0.05) . On day 14, the counts of peripheral blood monocytes and lymphocytes in the DAS high dose intervention group increased by 136.36%, 260.00% (P<0.05) ; On day 29, the counts of White blood cells, lymphocytes, red blood cells, platelets, hemoglobin in the DAS low, middle and high dose intervention groups increased (P<0.05) ; spleen weight, spleen index, white pulp area ratio of spleen, thymus weight, thymus index, thymic cortex area ratio of mice in the DAS high dose intervention groups increased (P<0.05) . Conclusion: DAS can effectively suppress benzene-induced leucopenia in mice.
