C-type natriuretic-peptide-potentiated relaxation response of gastric smooth muscle in streptozotocin-induced diabetic rats

Figure 1 Comparison of gastric smooth muscle contractilities between normal and diabetic rats. A, B: The row traces gastric smooth muscle spontaneous contractions in normal and diabetic rats; C, D: Summary of the contractility in normal and diabetic rats. The contractility per weight of gastric smooth muscle strip was not significantly different between normal and diabetic rats (A-C, n = 8, P > 0.05). However, the frequency of spontaneous contraction was significantly depressed in diabetic rats (A, B and D, n = 8, ^aP < 0.01).
