Abstract:
OBJECTIVE：To inv estigate the tonifying blood effects of different extract parts of Embelia parviflora on blood deficiency model mice ，and to explore its mechanism. METHOD S：Totally 70 mice were randomly divided into blank control group（water），model control group （water），positive control group （Danggui buxue oral liquid ，324 g/kg），petroleum ether ， ethyl acetate ，n-butanol and water parts of E. parviflora groups（4.2，10.64，22.07，5.0 g/kg respectively ，calculated by the extractum），with 10 mice in each group. The mice were given medicine intragastrically ，once a day ，for consecutive 14 d. Except for blank control group ，other groups were given intraperitoneal injection of cyclophosphamide （80 mg/kg）on 12th and 13th day of starting administration to induce blood deficiency model. 30 min after last administration ，automatic hematology analyzer was used to detect the levels of peripheral hemogram indexes （WBC，RBC，HCT，PLT，HGB）；the levels of IL- 2，IL-3，IL-6，EPO， G-CSF，M-CSF and VCAM- 1 were determined by ELISA ；thymus and spleen indexes were calculated. RESULTS ：Compared with blank control group ，peripheral hemogram indexes levels ，serum levels of IL- 2，IL-3，IL-6，EPO，G-CSF，M-CSF，VCAM-1 and thymus index were decreased significantly ，while spleen index was increased significantly （P＜0.01）. Compared with model control group，there was no statistical significance in above indexes of mice in petroleum ether part of E. parviflora group（P＞0.05）. The levels of RBC ，HGB，PLT，the serum levels of IL- 2，IL-6，G-CSF，M-CSF，VCAM-1 and thymus index in ethyl acetate part of E. parviflora group were significantly increased （P＜0.05 or P＜0.01），while there was no statistical significance in other indexes （P＞0.05）. Except for no significant increase of WBC in water part of E. parviflora group，above peripheral hemogram indexes ， serum indexes and thymus index of n-butanol group and water part of E. parviflora group were increased significantly while spleen index was decreased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS：The ethyl acetate ，n-butanol and water parts of E. parviflora can improve immunological function and the expression of hematopoietic factors in blood deficiency model mice ，and shows certain blood tonifying effects.
