非胰岛素依赖型糖尿病人缺锌对部分免疫功能的影响

对３４例非胰岛素依赖型糖尿病（ＮＩＤＤＭ）患者在用一般降糖治疗后血糖稳定时加用锌剂，检测补锌前后免疫功能和血清锌含量的改变。结果发现：糖尿病红细胞受体花环（ＲＢＣ＿Ｃ３ｂＲＲ），Ｔ淋巴细胞亚群（ＣＤ３，ＣＤ４，ＣＤ４／ＣＤ８）及血清锌均低于正常对照组，而ＣＤ８及红细胞免疫复合物花环（ＲＢＣ－ＩＣＲ）高于对照组，经补锌治疗一月后，糖尿病组血清锌，ＲＢＣ－Ｃ３ｂＲＲ，ＲＢＣ－ＩＣＲ，ＣＤ３，ＣＤ４诼Ｃ

Influence of insufficient zinc on immune functions in NIDDM patients]

The serum zinc level and immune functions were analyzed in 34 patients with NIDDM before and after the treatment with zinc gluconate supplement during conventional therapy (after the blood glucose level stabilization). The results showed that before treatment the level of serum zinc and red cell C3b receptor rosette(RBCK-C3b RR), T-lymphocyte subgroup CD3, CD4, and CD4/CD8 were decreased(P < 0.01), while CD8, red cell immune complex rosette(RBC-ICR) were increased. After treatment with zinc gluconate for 1 month the serum zinc level, RBC-C3b RR, RBC-ICR, CD3 and CD4/CD8 became normal, CD8 also approached to normal. All the above figures were significantly different before and after zinc therapy. The data showed that various degrees of lowering of serum zinc and abnormal immune functions were present during the conventional antidiabetic therapy. Thus, zinc supplement should be used as an important adjunctive therapy for NIDDM patients.
