Effects of capsaicin on the circular muscle motility of the isolated guinea-pig ileum.
Effects of capsaicin on the circular muscle motility of the isolated guinea-pig ileum were investigated. Capsaicin produced a contraction followed by a relaxation of the circular muscle. Both responses were easily desensitized. As the late relaxation response was not sufficiently intense to be analyzed, the inhibitory effect of capsaicin on substance P-induced contractions was explored. Capsaic...
متن کاملMuscarinic cholinergic stimulation of phosphatidylinositol turnover in the longitudinal smooth muscle of guinea-pig ileum.
1. The metabolism of phosphatidylinositol and phosphatidate was investigated in fragments of longitudinal smooth muscle from guinea-pig ileum incubated with cholinergic and anticholinergic drugs. 2. Incorporation of Pi into these lipids was enhanced by acetylcholine and carbamoylcholine. 3. The receptor responsible for triggering this response was of the muscarinic type, since (a) the response ...
متن کاملInteractions of neurogenic responses of longitudinal and circular muscle in the guinea-pig ileum.
The relationship between neurogenic responses of longitudinal and circular muscle was studied by measuring contractions and EMG or nonadrenergic, non-cholinergic (NANC) relaxations and NANC inhibitory junction potentials in different preparations of the guinea-pig ileum. NANC relaxation of longitudinal muscle was observed also without any preceding or concomitant circular muscle contraction rul...
متن کاملENDOGENOUS RELEASE OF OPIATES BY REPETITIVE ELECTRICAL FIELD STIMULATION IN THE GUINEA-PIG AND RAT ILEAL LONGITUDINAL MUSCLE
The effect of repetitive electrical field stimulation and the response of the guinea-pig and rat ileal longitudinal muscle to single pulse stimulations was examined. Single pulse field stimulation produced twitch contraction which was inhibited by repetitive field stimulation (10 Hz, 40V, 0.5 msec for 5 m). This inhibition was largely, though never completely, reversed by naloxone. Contrac...
متن کاملAntihistaminic activity of carane derivatives in isolated guinea pig ileum.
Local anesthetics (LAs) inhibit membrane depolarization by reducing sodium and potassium conductance, and subsequent displacement of calcium ions from binding sites seems to occur. Histamine release appears to be a secretory process in which calcium couples the stimulus to the exocytosis of histamine-containing granules. Furthermore, LAs are structurally similar to histamine H(1)-receptor antag...
