Abstract
Studies were performed to investigate the effect of prostaglandin E2 on esophageal motility in 12 healthy volunteers. PGE2 infusion caused a dose-dependent reduction in the lower esophageal sphincter pressure. The threshold dose was less than 0.05 mug-kg-1-min-1 and maximal reduction of pressure (60%) occurred with a dose of 0.4 mug-kg-1-min-1. In contrast to its effect on the lower esophageal sphincter, PGE2 did not alter the pressure in the upper esophageal sphincter. PGE2 did not influence resting esophageal pressures; the amplitude of peristaltic contractions was reduced in the lower but not in the upper part of the body of the esophagus. These studies show that in man PGE2 exerts selective inhibitory influence on the activity of the lower part of the esophagus and lower esophageal sphincter which are composed of smooth muscle fibers.

Abstract
The blood histamine levels, basophil and eosinophil counts and the percentage of vacuolated eosinophils were observed in 30 controls and 15 patients of urticaria. There was a definite rise in eosinophil and basophil count during the acute stage of the disease which decreased in the quiescent or the symptom-free stage. The behavior of blood histamine level was similar. The mechanisms involved are discussed.

Abstract
The purpose of the present study was to investigate the nature of the vagal inhibitory innervation to the lower esophageal sphincter in the anesthetized opossum. Sphincter relaxation with electrical stimulation of the vagus was not antagonized by atropine, propranolol, phentolamine, or by catechloamine depletion with reserpine. A combination of atropine and propranolol was also ineffective, suggesting that the vagal inhibitory influences may be mediated by the noncholinergic, nonadrenergic neurons. To determine whether a synaptic link with nicotinic transmission was present, we investigated the effect of hexamethonium on vagal-stimulated lower esophageal sphincter relaxation. Hexamethonium in doses that completely antagonized the sphincter relaxation in response to a ganglionic stimulant, 1,1-dimethyl-4-phenylpiperazinium iodide (DMPP), did not block the sphincter relaxation in response to vagal stimulation at 10 pulses per second, and optimal frequency of stimulation. A combination of hexamethonium and catecholamine depletion was also ineffective, but hexamethonium plus atropine markedly antagonized sphincter relaxation (P less than 0.001). Moreover, 4-(m-chlorophenyl carbamoyloxy)-2-butyltrimethylammonium chloride (McN-A-343), a muscarinic ganglionic stimulant, also caused relaxation of the lower esophageal sphincter. We suggest from these results that: (a) pthe vagal inhibitory pathway to the sphincter consists of preganglionic fibers which synapse with postganglionic neurons: (b) the synaptic transmission is predominantly cholinergic and utilizes nicotinic as well as muscarinic receptors on the postganglionic neuron, and; (c) postganglionic neurons exert their influence on the sphincter by an unidentified inhibitory transmitter that is neither adrenergic nor cholinergic.

Abstract
We performed studies in the opossum to define the influence of the vagi in the control of lower esophageal sphincter (LES) function. Bilateral vagotomy caused transient sphincter hypertension which was prevented by phentolamine and by atropine. Stimulation of the peripheral end of vagus, after bilateral cervical vagotomy, caused relaxation of the LES over a wide range of frequency and intensity of electrical stimulation. The relaxation was less marked at the lower frequencies of stimulation, and atropine treatment did not enhance this relaxation. In other experiments, atropine treatment reversed the rise in gastric (fundic) pressure with the vagal stimulation, but atropine did not enhance the degree of LES relaxation. Stimulation of the central end of the vagus caused an increase in LES pressure due to a centrally mediated reflex; the efferents for this motor response were not present in the vagi, as the reflex contraction persisted after bilateral vagotomy. The LES contraction with the stimulation of the vagal afferents was antagonized by phentolamine as well as by atropine. These studies suggest that: (a) the vagi do not mediate any cholinergic excitatory influences to the LES and the vagal influence of the sphincter is entirely inhibitory; (b) the vagi carry afferent fibres for a centrally mediated neural reflex which contracts the LES, but the efferent path of this reflex arc does not lie in the vagi.

Abstract
The purpose of this study was to evaluate the mechanical factors involved in the genesis of lower esophageal sphincter pressure. We determined the relationship between intraluminal pressure and inside diameter, estimated the ratio between the wall thickness to inside radius, and calculated the tension in the wall of the lower esophageal sphincter as a function of the inside diameter. Various degrees of circumferential stretch were applied by introducing probes of different diameters in the rat lower esophageal sphincter in vivo. The intraluminal pressure produced by the lower esophageal sphincter around each probe was measured and pressure-diameter curves were constructed during (a) resting state, (b) contraction produced by electrical stimulation, and (c) relaxation produced by esophageal distension. The intraluminal pressure at an inside diameter of 0.5 mm was similar to that at inside diameter of 3.2 mm. This was true for the sphincter at rest as well as upon electrical stimulation. The pressure diameter curve, however, was sigmoid in shape; at first it showed a decline and then an increase followed by decline in pressure again with increasing diameters. The ratio of wall thickness to inside radius or the magnification factor varied with inside diameters as expected and this ratio increased steeply at small inside diameters. The tension diameter curves of the sphincter muscle showed that optimal tension development occurred not near sphincter closure but at a much wider diameter of 3.2 mm and that this muscle developed tension even at small luminal diameters. This behavior of the sphincter muscle ensures effective intraluminal pressure over a wide range of luminal diameters.

Abstract
The intravenous injection of prostaglandin E(1) (PGE(1)) causes a dose-dependent relaxation of the lower esophageal sphincter (LES) in the intact, lightly anesthetized opossum. The action of PGE(1) is not inhibited by the drugs that produce muscarinic or nicotinic cholinergic antagonism or alpha and beta adrenergic antagonism in the doses that inhibited the action of respective agonists. Moreover, this action is not affected by exogenous gastrin pentapeptide. The action of PGE(1) on the LES is mimicked by isoproterenol, theophylline ethylenediamine, and dibutyryl cyclic AMP. Both theophylline, a phosphodiesterase inhibitor, and isoproterenol, an adenyl cyclase stimulator, added to the action of PGE(1). On the other hand, adenyl cyclase inhibitor nicotinic acid, as well as phosphodiesterase stimulator, imidazole inhibited its action. Further, both nicotinic acid and imidazole inhibited the degree of LES relaxation produced by esophageal distension. These studies suggest that intracellular cyclic AMP may act as the "second messenger" in the regulation of the lower esophageal sphincter relaxation.

Abstract
Pressure-diameter curves of the esophagus were obtained to define its mechanical properties. The mucosal contribution to the strength of the esophagus was negligible until the outer diameter almost doubled, suggesting that small intraluminal pressures are held by the muscle layer alone. For larger deformations mucosal contribution increased and at failure the mucosa held over one-half of the failure pressure of the esophagus. The paths followed during loading and unloading are different and exhibit hysteresis. They are influenced by the rate of pressure change, being more compliant for low rates of pressure change. They are influenced by the history of loading, being different for successive loading-unloading cycles. If enough loading-unloading cycles are repeated a stable loop is reached, which does not change thereafter. Both the mucosa and the whole esophagus show increasing stiffness with increasing pressure. This behavior can be represented by a simple exponential relationship. However, at rapid rates of pressure increases, the esophageal muscles produce sigmoid loading curves, which gradually become exponential when repeating loading.
