ABSTRACT

Objective To observe the effect o f selective prostaglandins EP 1 receptor antagonist SC19220 on the afferent activity of C unit in the saphenous nerve of diabetic rats. Methods The response of C units to sustained 1 min threshol d and suprathreshold stimuli was measured following intradermal injection of EP 1 receptor antagonist SC19220 into the receptive field of C unit of the sa phenous nerve in control and diabetic rats. Results The mechanical threshold of C units in diabetic rat s was obviously decreased compared with that of control rats (P
