Study of the effect of Shuanghongtong Decoction on diabetic neuropathy peripheral / 中成药

ABSTRACT

Objective: To investigate the curative effects of Shuanghongtong Decoction (Flos carthami, Radix Ginseng Rubra and Radix Ophiopogonis) diabetic neuropathy peripheral (DPN) and its mechanism.Methods:28 DPN patients were treated with Shuanghongtong Decoction for 3 weeks. The symptom and the peroneal nerve conduction velocity (SNCV) were observed before and after the experiments respectively. The diabetic rats reduced by STZ were treated with the same decoction for 4 weeks, at the end of the experiments the nerve conduction velocity (NCV) and the activity of aldose reductase (AR) were measured.Results: Some symptoms such as acra pain, numbness, asthenia and the peroneal SNCV were significantly improved after treatment with decoction. The animal experiments showed that the NCV were significantly increased and the activity of AR significantly decreased in diabetic rats as compared with the normal rats.Conclusion: Shuanghongtong Decoction could improve the symptom and increase the NCV of DPN. It's mechanism may be through inhibiting the activity of AR then improving the diabetic metabolism disorder.
