The bladder is composed of smoothmuscle tissue, collagen and elastic tissue. The large arteries have media rich in elastin and collagen, whereas media of smaller muscular arteries are rich in vascular smoothmuscle. In addition, smoothmuscle was present focally in their lining giving a resemblance to veins. In low birth weight infants, the vascular smoothmuscle of the persistent arterial duct can usually constrict beyond infancy. Recent evidence indicates that the responsiveness of cerebrovascular smoothmuscle to vasoregulators is altered by hypothermia. Magnesium sulfate, through competitive inhibition of calcium transport impedes myometrial smoothmuscle contraction in vitro. It binds to oxytocin receptors and causes rhythmic contractions of uterine smoothmuscle, increases the frequency of contractions and increases uterine tone. In turn these depend upon the state of constriction of the vascular smoothmuscle and of the physical structure of the vessel. Since smoothmuscle actin mediates contractile responses, an increase in its expression is likely to facilitate propulsive forces required for worm expulsion. Multiple connexins form gap junction channels in rat basilar artery smoothmuscle cells. Intercellular connections between smoothmuscle cells : the nexus. Vascular reactivity and structural remodelling share many signalling pathways in the smoothmuscle cell and the close relation between structural and functional abnormalities in pulmonary hypertension will be discussed.

Compliance or distensibility is dependent on the amount, arrangement and characteristics of the wall connective tissue and smoothmuscle as well as the level of vascular tone. Mechanical stretch and progesterone differentially regulate activator protein-1 transcription factors in primary rat myometrial smoothmuscle cells. Filament organization and contractile function in vertebrate smoothmuscle. This review explores the activation of the myometrium at labour onset, focussing on mechanisms of uterine contractility, including those proteins that play an important role in smoothmuscle contractility. The wall of the left coronary arterial aneurysm was mainly composed of smoothmuscle fibres with focal collections of elastic fibres and no evidence of pooling of mucopolysaccharides. Effect of lipids and aldehydes on gap-junctional intercellular communication between human smoothmuscle cells. Contribution of collagen, elastin, and smoothmuscle to in vivo human brachial artery wall stress and elastic modulus. A period of residence at lower altitudes or oxygen therapy may help reduce the amount of pulmonary arterial smoothmuscle and thus alleviate perioperative morbidity and mortality. Staining for glycosamino-glycans shows the prominence of ground substance formed by the activated smoothmuscle cells, rather than the reduplicated elastic and collagen layers that are characteristic of fibroelastosis. The endothelium is vital for vascular homeostasis: it has many diverse roles including regulation o f cellular interaction with the vessel wall, coagulation, vascular tone and smoothmuscle cell proliferation. The obligatory role of endothelial cells in the relaxation of arterial smoothmuscle by acetylcholine. Long-term observations of spontaneous electrical activity of uterine smoothmuscle. Activation of adenyl cyclase in human myometrial smoothmuscle cells by neuropeptides. Identification of oxidative stress-regulated genes in rat aortic smoothmuscle cells by suppression subtractive hybridization. Interstitial cells: involvement in rhythmicity and neural control of gut smoothmuscle. Regulation and modulation of calcium channels in cardiac, skeletal, and smoothmuscle cells. Isolation and characterization of inositol trisphosphate receptor from smoothmuscle. By 15 weeks postimplantation, they exhibited remarkable matrix remodelling with production of abundant elastic and collagen fibres and orientation of smoothmuscle cells perpendicular to the direction of blood flow. Evaluation of sections stained for elastin, smoothmuscle and connective tissue revealed a generally mild degree ofarterialization of all recognizable venous tributaries in all lobes drained by a surgically-banded vein. It is possible, however, that given this high degree of vasoreactivity there are also individual variations in calibre under normal conditions that reflect local changes in vascular smoothmuscle tone. A transient relaxation of smoothmuscle, with an associated brief episode of hypotension, flushing and reflex tachycardia, has been observed with rapidly administered intravenous bolus injections. Modulation of calcium movements by nitroprusside in isolated vascular smoothmuscle cells. Stretch-induced membrane depolarization in ferret trachealis smoothmuscle cells. Amylnitrite: use as a smoothmuscle relaxant in difficult preterm cesarean section. After denudation, arteries from the vascular smoothmuscle. The drug is thought to affect smoothmuscle cells in the colon and is, thus, expected to relax the muscles and thereby decrease spasms (6;12;26). Most of the structural differences as described before are in the media, the large arteries being rich in elastic and collagen fibres and the small arteries in smoothmuscle cells. In the absence of calcium, the development of smoothmuscle tone is prevented and the lumen-pressure relationship is largely determined by the connective tissue in the vascular wall extracellular matrix. Metaanalysis of smoothmuscle relaxants in the treatment of irritable bowel syndrome. Electrophysiological proprieties of uterine smoothmuscle. Ultrastructure of vascular smoothmuscle. Filament organization in vertebrate smoothmuscle. Excitability in uterine smoothmuscle. The smoothmuscle surrounding the airways goes into involuntary spasm and tightens, thus preventing people from breathing out and losing more carbon dioxide.
