title: Endothelin-1 and okadaic acid induced contractions in tracheal smooth muscle of lamb.
abstract: Stimulation of lamb tracheal smooth muscle fibre strips with endothelin-1 and okadaic acid results in the development of isometric tensions which are long lasting. However, endothelin-1 is more potent constrictor than okadaic acid. An analysis of 20,000 Da regulatory myosin light chain by two-dimensional gel electrophoresis shows an identical phosphorylation pattern.
