Effect of oxytocin on rat circular muscle strips from the gastric antrum. (A) is a summary of the effect of oxytocin on gastric smooth muscle strip. Oxytocin dose-dependently produced contraction in the range of 10−9 to 10−5 M. (B) is a representative trace illustrating that 100 nM oxytocin induced contraction in gastric circular muscle strips. (C) is a summary graph showing that oxytocin treatment dose-dependently significantly increased the contraction. (D) is a summary graph trace illustrating that 100 nM oxytocin induced contraction in gastric circular muscle strips. Data expression is in mN of force. Values are mean ± SEM. n = 11.
