This study was designed to clarify the mechanism of the inhibitory action of a nitric oxide (NO) donor, 3-morpholino-sydnonimine (SIN-1), on contraction, cytosolic Ca2 level ([Ca2]i), and ionic currents in guinea-pig ileum. SIN-1 (0.01∼100μM) inhibited 25 mM KCl- or histamine (10μM)-induced contraction in a concentration-dependent manner. SIN-1 reduced both the 25 mM KCl- and the histamine-stimulated increases in muscle tension in parallel with decreased [Ca2]i. Using... -
Modulation of Outward Potassium Currents by Nitric Oxide in Longitudinal Smooth Muscle Cells of Guinea-pig Ileum

To investigate the possible involvement of outward potassium (K+) currents in nitric oxide-induced relaxation in intestinal smooth muscle, we used whole-cell patch clamp technique in freshly dispersed guinea-pig ileum longitudinal smooth muscle cells. When cells were held at 60 mV and depolarized from 40 mV to 50 mV in 10 mV increments, sustained outward K+ currents were evoked. The outward K+ currents were markedly increased by the addition of 10 ㄍM sodium... -

The Eeffect of Sodium Nitroprusside on Muscle Tension in Guinea-pig Ileum. Seong Chun Kwon， Si Yeon Kim， Eun Ju Kim， and Bok Soon Kang Department of Physiology， Yonsei University College of Medicine， Seoul 120 -752， Korea Nitric oxide (NO) has been known as a mediator of nonadrenergic， noncholinergic inhibitory neurotransmitter in intestinal smooth musc1es. It has been suggested that NO donor such as sodium nitroprusside (SNP) produces relaxation of smooth musc1e via activation of...
