(17) Pretreatment of the vas deferens with both HNBTG and 2'-deoxycoformycin eliminated the difference in inhibitory potency between adenosine and 2-chloroadenosine.
(18) We interpret these results to indicate that angiotensins stimulate PGE production by adrenergic nerves in the vas deferens and that released norepinephrine mediates a part of the PGE production in response to the angiotensins.
(19) The effects of the ATP affinity label periodate-oxidized ATP (ATP-2',3'-dialdehyde; P-ATP) on contractile responses of the guinea pig vas deferens to ATP was characterized and compared to the effects of the specific P2x-purinoceptor photoaffinity label antagonist, arylazido aminopropionyl ATP (ANAPP3).
(20) Knowledge of the mechanical properties of the vas deferens is important in order to understand the mechanical interaction between an intravasal device (IVD) and the vas deferens--a necessary step for successful long-term implantation.
Vasomotor
Definition:
(a.) Causing movement in the walls of vessels; as, the vasomotor mechanisms; the vasomotor nerves, a system of nerves distributed over the muscular coats of the blood vessels.
Example Sentences:
(1) The vascular endothelium is capable of regulating tissue perfusion by the release of endothelium-derived relaxing factor to modulate vasomotor tone of the resistance vasculature.
(2) They are best explained by interactions between central sympathetic activity, brainstem control of respiration and vasomotor activity, reflexes arising from around and within the respiratory tract, and the matching of ventilation to perfusion in the lungs.
(3) We conclude that the rat somatosympathetic reflex consists of an early excitatory component due to the early activation of RVL-spinal sympathoexcitatory neurons with rapidly conducting axons and a later peak that may arise from the late activation of these same neurons as well as the early activation of RVL vasomotor neurons with more slowly conducting spinal axons.
(4) Cryosurgical treatment of chronic vasomotor rhinitis provides a safe, effective and uncomplicated mode of management for this very common otolaryngologic disorder.
(5) Diminished pressor responsiveness was considered to be due to concurrent reduction of central sympathetic vasomotor activity, because sympathetic nerve responses to hypothalamic stimulation were appreciably lessened in tripamide-treated SHR.
(6) Transient peripheral vasomotor constriction and heart rate increases were initiated within an 8- to 12-sec period following target detection with the predictable schedule, with subjects evincing greater responsivity than their nonpredictable schedule counterparts.
(7) Although true in asphyxia, breathing activates lung mechanoreceptors which reduce vagal outflow and apparently, in humans, abolishes sympathetic vasomotor activity (SNA).
(8) Other antidromically activated neurons in the vasodepressor region may be inhibitory vasomotor cells with a function relatively independent of baroreceptor inputs, or they may be A1 catecholamine neurons, with axons passing through the rostral medulla en route to the forebrain.
(9) Diagnostic characteristics of RSDS are: spontaneous burning pain, hyperalgesia, vasomotor disturbances, exacerbations by emotional upset, occurrence either spontaneously or after minor injury, occasional spontaneous resolution, extension to other body parts, and relief by sympathetic denervation.
(10) The data indicate that the thermoregulatory state profoundly influences the extent and direction of various cutaneous vasomotor reflex responses.
(11) We describe a patient with melorheostosis who showed improvement in pain and vasomotor function after treatment with nifedipine.
(12) Nonspecific vasomotor effects including shock and renal and hepatic failure are also discussed.
(13) In the pulmonary artery the vasomotor responses expressed as maximal dilatation had the order: ACh greater than VIP = PACAP while the order of potency was PACAP = VIP greater than ACh.
(14) It is likely that CGRP release from sensory neurons may play a role in the regulation of vasomotor responses, but no evidence for a role of CGRP in glandular secretion was found.
(15) These experiments suggest that vasopressin stimulates the activity of vasomotor neurons in the rostral ventrolateral medulla by a mechanism that involves a neuronal V1 receptor.
(16) It is concluded that selective, G protein-coupled, CGRP receptors are present in the media of bovine coronary arteries; there are both regional and species differences in the distribution of CGRP binding sites in coronary arteries and endogenous CGRP may exert a tonic influence on coronary vasomotor tone.
(17) Pulmonary human vasomotor effects of purine nucleotides are unknown.
(18) To determine the distribution of resistance in the coronary vasculature, measurements of microvascular pressure and diameter were obtained with vasomotor tone intact and during coronary dilation produced by papaverine.
