WebACh and histamine will cause a concentration-dependent contraction of the guinea pig ileum sections; The muscarinic antagonist atropine will inhibit contractions to ACh but not histamine, whereas the histamine antagonist mepyramine will inhibit contractions to histamine but not ACh. Experimental set-up. In this experiment you will work in pairs. WebHistamine produces a dose dependent contraction of guinea pig ileum smooth muscle. Two responses of the standard histamine are taken. The does are adjusted such that one is giving response of approximately 20% and other 70% of the maximum.
