RESUMEN
Objective To explore the protective effect of Sijunzi decoction and Danggui Buxue decoction on the immunological function in tumor-bearing mice treated by cyclophosphamide.Methods Transplantable carcinomas animal model were constructed by inoculating tumor cell to mice for 24 hours,and randomly divided into five groups.Tumor-bearing control group were reveived normal saline 0.2 mL per mice one day by intraperitoneal injection,and normal saline 0.4 mL per mice each day by intragastric administration.Cyclophosphamide group were reveived CTX 20 mg per kg weight each day,and normal saline 0.4 mL per mice each day.Sijunzi decoction and Danggui Buxue Decoction low dose group were reveived CTX 20 mg per kg weight each day and traditional Chinese medicine 0.1 g per mice each day.Sijunzi decoction and Danggui Buxue Decoction mediate dose group were reveived CTX 20 mg per kg weight each day and traditional Chinese medicine 0.2 g per mice each day.Sijunzi decoction and Danggui Buxue Decoction high dose group were reveived CTX 20 mg per kg weight each day and traditional Chinese medicine 0.4 g per mice each day.The weight indices of thymus gland and spleen,NK-cell activity and the proliferation of T-lymphocyte in five groups were measured after ten 10 days treatment.Results The weight indices of thymus gland and spleen,NK-cell activity and the proliferation of T- lymphocyte were increased in all three Sijunzi decoction and Danggui Buxue decoction groups,especially in Sijunzi decoction and Danggui Buxue decoction mediate and high dose group,the differences between them and CTX group were statistically significan(P<0.05,P<0.01).Conclusion Sijunzi decoction and Danggui Buxue decoction can antagonize the decrease of immunological function in tumor-bearing mice treated by chemotherapy.
