Quercetin inhibits anaphylactic contraction of guinea pig ileum smooth muscle.
Certain flavonoids inhibit antigen-induced release of histamine from mast cells and basophils and also inhibit contraction of guinea pig ileum induced by histamine, acetylcholine, and PGE2. We examined the effect of one flavonoid, quercetin, on anaphylactic smooth muscle contraction of ileum from guinea pigs sensitized to egg albumin. Quercetin inhibited both the phasic and tonic components of ...
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...
متن کاملFlow fields generated by peristaltic reflex in isolated guinea pig ileum: impact of contraction depth and shoulders.
The guinea pig ileum responds to distension with characteristic wall movements, luminal pressure gradients, and outflow (the peristaltic reflex). To date, little is known about whether the peristaltic reflex generates flow events other than laminar flow. Here we used a numerical method to solve for the flow generated by moving walls to assess occlusive contractions (case 1), nonocclusive contra...
متن کاملEffect of Matricaria chamomilla extract on the electrically stimulation of ileum of guinea-pig in invitro model
Previous studies indicate that Matricaria chamomilla (MC), a folk remedy plant, is very useful in the treatment of spasmogenic bowel diseases but the way of its action is not clear. For this purpose, we studied the effect of MC extract on the electrically activation in Guinea-Pig ileum in an invitro model. We used guinea pig in this study. After of kill, we brouhght out a piece of ileum and fix...
متن کاملExcitation-Contraction Coupling in Isolated Guinea Pig Ventricular Myocytes
Lysophosphoglyceride accumulation in ischemic myocardium has been implicated as a cause of arrhythmias. We examined the effects of lysophosphatidylcholine (LPC) in isolated guinea pig ventricular myocytes. In paced myocytes loaded with the Ca2+ indicator Indo-I-AM and studied at room temperature, 20 jiM LPC caused an initial positive inotropic effect followed by spontaneous automaticity, a decl...
