六味地黄苷糖对悬吊应激小鼠生殖内分泌及免疫系统的影响

目前尚无有效可靠的抗应激药物.传统的补益中药六味地黄汤（LW）对多种类型应激所致内分泌和免疫平衡失调具有明显调节作用,但目前已上市的LW成药缺乏可靠的质量控制方法,其临床疗效的可靠程度难以估测.本课题组在前期研究中以免疫和内分泌活性评价为导向,从LW中追踪分离并组成了质量可控且安全性好的六味地黄苷糖（LW-AFC）.本文观察了悬吊应激雌性小鼠生殖内分泌及免疫系统的变化及LW-AFC的影响.结果表明,悬吊应激小鼠皮质酮升高,动情期缩短、动情间期延长,垂体LH下降,动情间期血清E2升高;脾细胞培养上清IgG含量明显降低;口服LW-AFC能显著降低血清皮质酮,升高垂体LH,且LW-AFC能明显降低动情间期血清E2,并能明显增强脾细胞IgG分泌能力.这提示,悬吊应激可导致雌性小鼠生殖内分泌功能紊乱以及免疫功能下降,口服LW-AFC具有明显调节作用,对应激所致生殖内分泌功能紊乱以及免疫功能下降具有潜在防治作用.

LW-AFC Improved or Restored the Disturbance of Reproductive Endocrine and Immune Function in Stress-Loaded Mice

There are no effective and reliable anti-stress drugs. Traditional Chinese Medicine Liu Wei Di Huang Decoction (LW) can interfere with the various types of stress-induced endocrine and immune imbalance. However, traditional LW lacks reliable quality control methods, and the reliability of its clinical efficacy is difficult to estimate. In our previous study we evaluated the immune and endocrine activity of different parts from LW separation, and then formed LW-AFC which has satisfactory quality control, security and activity. In this paper, we observe the impact of LW-AFC on the reproductive endocrine and immune system of suspension-stressed female mouse. The results show that the stress increased the serum cortisone, reduced estrus cycle, prolonged diestrus, decreased the pituitary LH, but increased serum E2 on diestrus cycle, and IgG in spleen cell culture supernatant was significantly reduced after suspension stress. LW-AFC could significantly decrease the cortisone level, increase pituitary LH, lower serum E2 on diestrus cycle, and could significantly enhance the ability of spleen cells secreting IgG. These results suggest that stress can lead to reproductive endocrine disorders and decreased immune function, and oral administration of LW-AFC may significantly regulate the stress-induced reproductive endocrine disorders and decreased immune function, which might be developed as a potential new anti-stress drugs.
