益肾康防治慢性肾盂肾炎的临床免疫学研究

目的：探讨慢性肾盂肾炎（CPN）与免疫功能的关系以及中药益肾康冲剂作用机理。方法：将120例CPN患者随机分为益肾康组、三金片组、西药组。采用单克隆抗体、琼脂扩散、放免分析及放免平衡法对CPN患者治疗前后及健康组的外周血T淋巴细胞亚群、血清免疫球蛋白、补体、尿液分泌型IgA以及细胞因子IL－2水平进行测定。结果：CPN患者T淋巴细胞亚群处于紊乱状态，血清免疫球蛋白、补体、尿液分泌型IgA含量均降低，细胞因子IL－2水平增高（P＜0．05或P＜0．01），治疗后益肾康组各项指标恢复正常（P＞0．05），而对照组虽有所恢复，但与健康组比较，仍差异有显著性（P<0．05或P＜0．01）。结论：CPN患者慢性阶段存在着一定程度的细胞免疫、体液免疫功能紊乱。益肾康冲剂能纠正免疫系统功能紊乱的状态，有效地控制本病的复发，减轻免疫病理损伤。

Clinical Immunological Study on Prevention and Treatment of Chronic Pyelonephritis with Yishenkang Granule

Objective: To investigate the relationship between chronic pyelonephritis (CPN) and immune function, and the therapeutic mechanism of Yishenkang granule (YSKG). Methods: One hundred and twenty patients of CPN were divided into 3 groups randomly, the YSKG group (treated with YSKG), the control A group (treated with Sanjin tablet) and the control B group (treated with western medicine). Serum levels of immunoglobulin (Ig), complement 3 (C3), interleukin 2 (IL 2), peripheral T lymphocyte subsets, and urinary secretory immunoglobulin A (sIgA) were determined before and after treatment with monoclonal antibody assay, agar diffusion method, radioimmunoassay (RIA), and radioimmuno equilibrium method, and compared with normal control. Results: There were disorders of T lymphocyte subsets in CPN, lowering of serum Ig, C3 and urinary sIgA, and increase of blood IL 2 (P<0 05 or P<0 01). These abnormalities could be normalized after YSKG treatment. Conclusion: Functional disorders of cellular and humoral immunity exist in CPN patients of chronic stage. YSKG could correct the immune functional disorder, control the recurrence of CPN effectively and alleviate the immunopathological damage.
