Effects of Y27632 or nicardipine on basal contractions of antrum, proximal colon, and fundus smooth muscles. Representative traces of antrum (A), proximal colon (B), and fundus (C) smooth muscles, recorded as described in Materials and Methods. D. cumulative data from 5 antrum, proximal colon, and fundus smooth muscles of the average percent inhibition of basal contraction (+/− SD). The relaxation of each smooth muscle tissue by 1μmol L−1 nicardipine and 10μmol L−1 SNP together was taken as 100% percent inhibition. *P < 0.05, **P < 0.01, significantly different from the control regions preceding the drugs.
