Table 2. Evaluation of NCV of sciatic nerve in each experimental group.

Groups	MNCV (m/s)	SNCV (m/s)	n
NCV was exmined after eight weeks intervention with glycyrrhizin acid in rats. Data are presented as mean±SD,n=6. Statistical analyses are performed by One-way ANOVA. *P<0.05vs. Control group; #P<0.05vs. Diabetic group. Rats of the Control and Diabetic groups received saline for eight weeks via gavage; rats of the Diabetic+GA group received glycyrrhizin acid (150 mg/[kg·day]) for eight weeks via gavage. GA: glycyrrhizin acid; NCV: nerve conduction velocity; MNCV: motor nerve conduction velocity; SNCV: sensory nerve conduction velocity.
Control	43.76±4.97	46.38±6.27	10
Diabetic	34.77±5.12*	38.81±7.01*	6
Diabetic+GA	40.05±4.68#	41.46±5.49#	7
