5种淫羊藿对软骨组织生长和软骨细胞增殖影响的对比研究

目的：对比研究心叶淫羊藿、箭叶淫羊藿、朝鲜淫羊藿、巫山淫羊藿和川西淫羊藿对软骨生长和软骨细胞增殖活性的影响。方法：以鸡胚股骨组织为研究对象,采用配对试验设计,把同一鸡胚的两个股骨组织分别分入对照组或实验组,每组共10个股骨组织。对照组股骨组织在不含中药的培养液中培养,实验组股骨组织在含3％淫羊藿提取物的培养液中培养。以软骨长度、软骨重量、软骨细胞增殖(MTT法)为指标观察5个品种淫羊藿的软骨生物活性。结果：心叶淫羊藿和箭叶淫羊藿实验组的股骨长度、股骨湿重、股骨干重及细胞增殖量指标均高于对照组(P＜0.01),而朝鲜淫羊藿、巫山淫羊藿和川西淫羊藿实验组的股骨长度、股骨湿重、股骨干重及细胞增殖指标与对照组结果相近,差异无显著性。结论：心叶淫羊藿和箭叶淫羊藿具有明确的促进体外软骨生长和软骨细胞增殖的作用,而朝鲜淫羊藿、巫山淫羊藿和川西淫羊藿品种没有表现出这种生物活性。

Effect of five species of Epimedium on growth of cartilage and proliferation of cartilage cell in vitro

Objective: To observe the effect of Epimedium brevicornum, E. sagittatum, E. koreanum, E, wushanense and E. elongntum on the growth of cartilage and proliferation of cartilage cell in vitro. Method: According to the paired design method, either femur of each chichen embryo was put into the control tube with the medium containing no Epimedium injection, and the other was put into the treated tube with the medium containing 3% Epimedium injection. The length and weight of cultured cartilage and proliferation of cartilage cell (MTT method) were used as the indices to observe the cartilage biological activities of the five species of Epimedium in culture. Result: The results showed that the indices of length, weight and MTT in the E. brevicornum and E. sagittatum group were significantly higher than those in the contral group, but the above indices in groups E. koreanum, E. wushanens and E. elongntum were similar to those of the control with no statistical difference. Conclusion: E. brevicornum and E.sagittatum can improve the growth of cartilage and proliferation of cartilage cell in vitro, and other three Epimedium have not the same effect in this test.
