... segment cut in half. The active wall tension developed in response to exogenous NE was significantly greater in the 4-mm one-ring segment length (8.50 ± 0.56 mN/mm) than in the two-ring 2-mm segment lengths (6.64 ± 0.38 mN/mm) while the EC 50 values were the same. The maximum tone (tension) developed...

... with the change in wall tension. Increased intraluminal pressure resulted in a monophasic increase in myosin phosphorylation that was significantly correlated with instantaneous wall tension. In general, norepinephrine induced larger [Ca 2+ ] i transients and a biphasic myosin phosphorylation pattern. The results...
