| Abstract;We examined the differences in Ca2+ sensitivity of contractile elements of the guinea pig ileal circular and longitudinal muscles to receptor agonists, carbachol(CCh) and histamine(His). In conclusion, the sensitivity to the receptor agonist of guinea pig longitudinal muscles was greater than that of circular muscles. In the experiment with a .BETA.-escin-treated skinned fiber specimen, although there was no difference in the Ca2+ sensitivity to contractile elements of both muscles, it was considered that the difference in the Ca2+ sensitivity to the receptor agonist was related to the changes in Ca2+ sensitivity of contractile elements via G protein, and that C kinase participation was small in the longitudinal muscles.
