四物汤对放射线致血虚证小鼠骨髓Epo和G-CSF基因表达的影响

目的:考察四物汤对放射线致血虚证小鼠的生血作用及对骨髓Epo,G-CSF基因表达的影响,为阐明四物汤补血作用的分子机制提供依据。方法:采用3.5Gy⁶⁰Coγ射线全身1次性照射,制备小鼠血虚证模型;检测外周血象;骨髓集落培养观察并计数CFU-GM,BFU-E,CFU-E,CFUmix;RTPCR检测骨髓Epo和G-CSF基因表达。结果:四物汤显著升高放射线致血虚证小鼠外周血白细胞数量和骨髓CFUGM,BFUE,CFUE,CFUmix数量,上调骨髓Epo和GCSF基因表达。结论:四物汤促进骨髓细胞Epo和G-CSF基因的表达可能是其生血作用的机制之一。

The effect of Siwu Tang on Epo and G-CSF gene expression in bone marrow of irradiated blood deficiency mice

OBJECTIVE: To observe the blood enriching function of Siwu Tang and its effect on Epo and G-CSF gene expressions in bone marrow of blood deficiency mice, and thus provide the basis for understanding the molecular mechanism of blood enriching function of Siwu Tang. METHOD: The animal model of blood deficiency were established in the mice by using 3.5 Gy60Co gamma-ray. Peripheral blood cells were analyzed and CFU-GM, BFU-E, CFU-E and CFU-mix were counted in bone marrow colony cultured. Both Epo and G-CSF gene expressions in bone marrow were measured with RT-PCR. Result: Siwu Tang significantly increased the number of peripheral blood cells and the amount of CFU-GM, BFU-E, CFU-E and CFU-mix in bone marrow and enhanced Epo and G-CSF gene expression in bone marrow in the mice with blood deficiency. Conclusion: The promotion of Epo and G-CSF gene expressions in bone marrow may be one of the mechanisms underlying the blood enriching function of Siwu Tang decoction.
