Abstract
Objective To observe the effect of jiaweibugan decoction on the expression of p-JNK mitogen-activated protein kinase in sciatic nerve of experimental diabetic rats and explore the preventive and therapeutic effects of Jiaweibugan decoction on peripheral neuropa-thy in experimental diabetic rats. Methods The diabetic rat model was established by streptozotocin (STZ). The rats were killed on the 4th or 8th week from the beginning of treatment, and the expression of p-JNK mitogen-activated protein kinase in sciatic nerve was detected by immunohistochemistry. Serum SOD was determined by xanthine oxidasemethod. Results The immunohistochemistry results showed that the expression of p-iNK in the model group on the 4th or 8th week was higher than that in normal control group (P<0.05) , while p-JNK in jiaweibugan decoction group was markedly lower than that in model rats(P<0.05). The results showed that SOD in the model group on the 4th or 8th week was lower than that in the normal control group (P<0.05) , while SOD in jiaweibugan decoction group was markedly high-er than that in model rats(P<0.05). Conclusion Jiaweibugan decoction has a preventive and therapeutic effect on peripheral neuropathy in experimental diabetic rats.
