background: at the present time, massage has become a popular therapy employed in complementary medicine. there is evidence showing that back massage might have many positive psychological effects, possibly due to having many autonomic nervous system afferent inputs. one of the frequent positions during massage is prone position. however, there has been limited research investigating the effect...

background : hypertension is a risk factor for life threatening diseases such as cerebrovascular accidents, coronary artery diseases, congestive heart failure and chronic renal failure. the prevalence of non-communicable diseases such as hypertension and diabetes including obesity has increased over the past few years in iran. the first step for modification of cardiovascular diseases in a defi...

background: both vitamin d deficiency and hypertension are prevalent in the general population. several observations indicate an association between vitamin d deficiency and high blood pressure. the present case-control study aimed to compare serum 25-hydroxyvitamin d (25-ohd) in hypertensive patients versus healthy controls. methods: one hundred patients aged 30-60 years with hypertension (htn...

The positive inotropic action of hexainethoniuin in hypodynamic and freshly prepared papillary muscles of the cat and the hypodynamic heart-lung preparation of the dog has been demonstrated. Within certain limits, there exists a proportionality between the concentration of hexamethonium and the magnitude of the inotropic response. In both preparations results have been obtained which indicate t...

In view of evidence implicating thyrotropin-releasing hormone (TRH) as a chemical mediator of synaptic transmission onto spinal sympathetic neurons, this peptide was administered intrathecally, in a dose of 6.5 nmol, at the T9 and T2 spinal levels in the anesthetized rat. At the lower thoracic level TRH increased arterial pressure and heart rate; these effects peaked at 4-7 minutes and decayed ...

Microinjection of the excitatory amino acid L-glutamate into the nucleus tractus solitarii (NTS) elicits decreases in arterial pressure and heart rate. In the present study, we sought to determine the regional hemodynamic effects that were correlated with changes in arterial pressure and heart rate produced by stimulation of the NTS. In anesthetized rats, blood flow in the renal (RBF), superior...

We tested the hypothesis that the antihypertensive effects of dietary taurine supplementation in deoxycorticosterone acetate (DOCA)-salt rats may be attributed to the suppression of sympathetic nervous system activity. In uninephrectomized rats treated with DOCA while receiving 1% NaCl solution for 2 weeks, systolic blood pressure was significantly increased as compared with that in control rat...

Although it is generally accepted that pilocarpine affects the postganglionic cholinergic receptors and reveals a strong muscarinic action selectively, evidence has been cited to conclude that the drug affects other sites of the effector organs. Large doses of the drug do not induce a rise of blood pressure in an atropinized animal. But Dale and Laidlaw (1), Marrazi (2) and Ambache (3) conclude...

THIS investigation was undertaken in an endeavour to decide if the methonium ganglion blocking compounds could be administered to cases of vascular hypertension who were known to be suffering from glaucoma, or to similar vascular hypertensive cases of a glaucomatous disposition although this might not be known, without the danger of subsequent sequelae such as an increase in intra-ocular pressu...
