温筋通对链脲佐菌素糖尿病大鼠血糖及坐骨神经终末期糖基化终产物的影响

目的：观察中药复方温筋通过糖尿病大鼠血糖、坐骨神经终末期糖基化终产物的影响。方法：采用链脲佐菌素糖尿病大鼠模型，随机分为预防组和治疗组，给予温筋通灌胃，并以氨基胍作为对照，治疗12周，观察温筋通过糖尿病大鼠血糖和坐骨神经终末期糖基化终产物的影响。结果：温筋通预防组和治疗组血糖、温筋通预防组和氨基胍组坐骨神经终末期糖基化终产物，均较模型组为低（P＜0．01）；氨基胍组血糖高于温筋通预防组（P＜0．05），与模型组比较，差异无显著性（P＞0．05）。结论：温筋通可能通过降低血糖、抑制终末期糖基化终产物在神经组织中的形成，从而预防糖尿病周围神经病变。

Effect of Wenjingtong Composita on Blood Glucose and Advanced Glycosylation End Products in Sciatic Nerve of Streptozotocin-Induced Diabetic Rats

OBJECTIVE: To investigate the effect of Wenjingtong Composita (WJTC) on blood glucose and advanced glycosylation end products (AGEs) in sciatic nerve of streptozotocin (STZ)-induced diabetic rats. METHODS: STZ-induced diabetic rats were randomized to WJTC prevention group and WJTC treatment group. The levels of blood glucose and AGEs in sciatic nerve of the animals were checked after 12 weeks treatment and compared with that of aminoguanidine (AG) treatment group. RESULTS: Blood glucose level in the WJTC prevention and treatment group, and AGEs in sciatic nerve of the WJTC prevention group and the AG group were lower than those of the non-treated group (P < 0.01). Blood glucose level in the AG group was higher than that in the WJTC prevention group (P < 0.05), but was not significantly different from that in the non-treated group (P > 0.05). CONCLUSION: WJTC might prevent diabetic peripheral neuropathy by decreasing blood glucose and inhibiting AGEs formation in sciatic nerve in STZ-induced diabetic rats.
