Role of BK_Ca in Stretch-Induced Relaxation of Colonic Smooth Muscle

Figure 4

The tension changes of colon smooth muscle strips induced by stretch stimulation. (a) The longitudinal muscle tension changes in the control group after stretch stimulation. (b) The effect of ChTX on the tension changes induced by stretch. (c) The effect of TEA on the tension changes induced by stretch. (d) and (e) Statistical data of the ratio of the stable muscle tone and the relevant stretched peak tension for longitudinal muscle (d) and circular muscle (e), respectively. Values are shown as means ± SEM, ; < 0.05, < 0.01, and < 0.001 versus control group; < 0.05 versus ChTX group.
