Ingia / Ingia

1. Experiments were carried out to test whether neosurugatoxin (NSTX) which blocks autonomic ganglia also acts centrally, like hexamethonium, on nicotinic cholinoceptors involved in the neural control of release of vasopressin and oxytocin from the neurohypophysis. 2. In the water-loaded rat under

Nicotine gum as a therapeutic approach for low blood pressure in Parkinson's disease: A randomized pilot study.

Ingia / Ingia

UNASSIGNED One cause for low blood pressure (BP) in Parkinson's disease (PD) is denervation of the sympathetic nervous system and reduced levels of norepinephrine. Nicotine increases heart rate and BP acutely by causing sympathetic stimulation. The absorption rate of nicotine gum is relatively quick

Nicotine Improves Survivability, Hypotension, and Impaired Adenosinergic Renal Vasodilations in Endotoxic Rats: Role of α7-Nachrs/HO-1 Pathway.

Ingia / Ingia

The nicotinic/cholinergic antiinflammatory pathway protects against acute kidney injury and other end-organ damages induced by endotoxemia. In this study, we tested the hypothesis that functional α7-nAChRs/heme oxygenase-1 (HO-1) pathway is imperative for the nicotine counteraction of hemodynamic

Ingia / Ingia

OBJECTIVE Significant hypotension after carotid endarterectomy (CEA) and carotid angioplasty with stenting (CAS) has been correlated with adverse outcomes. The objective of this study was to determine risk factors that predict hypotension after patients undergo CEA and CAS. METHODS The review

A cholinergic link in the reflex release of vasopressin by hypotension in the rat.

Ingia / Ingia

Inhalation of amyl nitrite in the water-loaded rat under ethanol anaesthesia produced a brief fall of blood pressure followed by a prolonged antidiuretic response. The antidiuretic response to amyl nitrite was accompanied by increased urinary excretion of vasopressin, it was blocked by a specific

Chronic Nicotine Exposure Abolishes Maternal Systemic and Renal Adaptations to Pregnancy in Rats.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Pregnancy is characterized by maternal systemic and intrarenal vasodilation, leading to increases in the renal plasma flow (RPF) and glomerular filtration rate (GFR). These responses are mainly mediated by nitric oxide (NO) and relaxin. The impact of cigarette smoking on the maternal adaptations to

Effects of alpha and beta adrenolytic agents on the changes in arterial pressure induced by intrahypothalamic injection of carbachol and nicotine.

Ingia / Ingia

In order to elucidate some aspects of cholinergic and adrenergic interaction in the dorsomedial nucleus of the hypothalamus and its effect on systemic arterial pressure, carbachol and nicotine were injected into this area alone or preceded by regitine and propranolol. Both carbachol and nicotine

Increased afferent vagal responses produced by epicardial application of nicotine on the canine posterior left ventricle.

Ingia / Ingia

Vagally mediated vasodepressor reflexes are observed in dogs and patients with acute myocardial ischemia or infarction and may be related to the Bezold-Jarisch reflex. To test whether nicotine and bradykinin produced site-specific vagal vasodepressor and sympathetic vasopressor responses,

The effect of nicotine on blood pressure in the genetically hypertensive mouse.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Mice genetically selected for high and low blood pressure were exposed to nicotine via a single injected dose or addition to drinking water for 52 weeks. In the acute study, the response of mice with high blood pressure was a statistically significant increase in blood pressure. In the chronic study

Identification and evaluation of the contribution of the chemoreflex in the hemodynamic response to intracarotid administration of contrast materials in the conscious dog: comparison with the response to nicotine.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Intracarotid administration of ionic contrast material and nicotine in conscious, unsedated dogs caused similar biphasic reflex responses consisting of initial decreases followed by increases in heart rate and pressures. Both phases were characterized by increases in respiratory amplitude. The

Experiments were carried out in cats anaesthetized with chloralose, (a) to examine the effect on blood pressure, heart rate and respiratory frequency produced by topical application of leptazol, nicotine and sodium pentobarbitone to the ventral surface of the medulla at an area around the rootlets

Inhibition by nicotine of the vasodilator effect of bradykinin: evidence for a prostacyclin-dependent mechanism.

Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

In urethane-anesthetized rabbits, bradykinin caused a dose-dependent hypotension. This hypotensive response was not altered in magnitude but was inhibited in duration after pretreatment with nicotine. Nicotine failed to inhibit the hypotensive effect of eledoisine, prostacyclin, isoprenaline and
