缩泉丸对肾阳虚多尿大鼠内分泌及免疫功能的影响

目的 观察缩泉丸对肾阳虚多尿模型大鼠内分泌及免疫功能的影响.方法 用腺嘌呤250 mg/kg灌服大鼠4周,造成肾阳虚多尿模型,分别给予缩泉丸、肾气丸和去氨加压素(dDAVP)治疗4周,检测缩泉丸对体重、脏器系数、血清中皮质酮浓度和外周血T淋巴细胞亚群水平的影响.结果 模型组大鼠体重比正常对照组大鼠明显降低,dDAVP组、缩泉丸中、高剂量组与模型组大鼠体重相比,具有显著性差异(P<0.05或P<0.01).与正常对照组比较,模型组大鼠胸腺、肾上腺和垂体系数明显降低(P<0.05或P<0.01);与模型组比较,除缩泉丸低剂量组外,其余各治疗组的胸腺系数均明显提高,差异具有显著性(P<0.05);与模型组比较,垂体和肾上腺系数,仅在肾气丸组和缩泉丸高剂量组发现有明显提高,差异具有显著性(P<0.05).模型组具有较低的血清中皮质酮浓度,与正常对照组比较,具有非常显著性差异(P<0.01),肾气丸组和缩泉丸中、高剂量组血清中皮质酮浓度比模型组明显增加,具有显著性差异(P<0.05或P<0.01).与正常对照组比较,肾阳虚多尿模型组大鼠外周血T淋巴细胞CD3+百分比、CD3+/CD4+百分比明显减少,CD3+/CD8+百分比明显增加,差异具有显著性(P<0.05或P<0.01);与模型组比较,肾气丸组和缩泉丸低、中、高剂量组CD3+百分比、CD3+/CD4+百分比明显增加,CD3+/CD8+百分比明显减少,差异具有显著性,与模型组相比dDAVP组CD3+百分比、CD3+/CD4+百分比和CD3+/CD8+百分比均无显著性差异.结论 缩泉丸能够调节肾阳虚多尿大鼠的内分泌及免疫功能.

Effects of Suoquan Wan on Endocrine and Immune Function of Polyuria Rats With Kidney-yang Deficiency

Objective To observe the effects of Suoquan Wan(SQW) on the endocrine and immune function of the polyuria rats with kidney-yang deficiency. Methods The model rats were induced by gastric infusion of adenine(250 mg/kg) for 4 weeks, then treated respectively with SQW (at low, middle and high dose respectively), Shenqi Wan and desmopressin for another 4 weeks. The bodyweight and organ index were recorded, and serum cortisone concentration were detected. T cell subsets in peripheral blood were determined by flow cytometry. Results The bodyweight of rats in model group was lower than that in the normal control group. And the bodyweight of rats in desmopressin group, middle-and high-dose SQW groups differed from that in the model group (P < 0. 05 or P < 0. 01). The decreased organ indexes of pituitary, adrenal and thymic glands were found in the model group (P < 0. 05 or P < 0. 01 compared with the normal group). The thymus index was elevated in all the medication groups except the low-dose SQW group (P < 0. 05). The elevated organ indexes of pituitary and adrenal glands were only found in Shenqi Wan group and high-dose SQW group (P < 0. 05). In the model group serum cortisone concentration was decreased (P < 0. 01). In Shengqi Wan group and middle-and high-dose SQW groups, the cortisone concentration was significantly increased (P < 0. 05 or P < 0. 01, compared with the model group). In the model group, the percentages of CD3+ and CD3+/CD4+ T cell subsets in pe-ripheral blood were decreased, and the percentage of CD3+/CD8+ T cell subset was increased (P < 0. 05 or P < 0. 01 compared with the normal group). Compared to the model group, the percentages of CD3+ and CD3+/CD4+ T cell sub-sets were increased and the percentage of CD3+/CD8+ T cell subset was decreased in SQW group and Shenqi Wan group. But the differences of T lymphocyte subsets were insignificant between desmopressin group and the model group. Conclu-sion SQW can regulate the endocrine and immune function of the polyuria ratwith kidney-yang deficiency.
