Background and aims: Primary hypertension, an unexplained increase in blood pressure (BP), accounts for 90% of the cases hypertension remains a critical public health challenge. This study aimed to investigate effects 12-week resistance training (RT) on some vasodilators vasoconstrictors hypertensive men. Methods: is semi-experimental study. A total 40 middle-aged men (45.3±3.2 years) with mode...

1. We have examined whether an increase of renal vascular resistance is generally accompanied by an inhibition of renin secretion. The effects of vasoconstriction produced by angiotensin II (Ang II), arginine-vasopressin (AVP), and potassium (KCl) depolarization on vascular resistance and on renin release from isolated rat kidneys perfused at constant pressure of 100 mmHg were investigated. 2. ...

It was the aim of the present study to get insight into some of the intracellular mechanisms by which the vasoconstrictor hormones angiotensin II (ANG II), arginine vasopressin (AVP), and norepinephrine (NE) inhibit renin release from renal juxtaglomerular cells. To this end a primary cell culture from rat renal cortex was established that consisted of 50% juxtaglomerular cells. The cultured ju...

BACKGROUND AND AIMS Hepatorenal syndrome is a severe complication of cirrhosis and associates with significant mortality. Vasoconstrictor medications improve renal function in patients with hepatorenal syndrome. However, it is unclear to what extent changes in serum creatinine during treatment may act as a surrogate for changes in mortality. We have performed a meta-analysis of randomized trial...

Orthotopic liver transplantation (OLT) in patients with end-stage liver disease is a procedure associated with high cardiac output, low systemic vascular resistance (SVR), coagulopathy and the potential for significant blood loss. A feature of hypertrophic obstructive cardiomyopathy (HOCM) is left ventricular outflow tract obstruction which may be exacerbated by reduced SVR, reduced filling pre...

Cardiac cephalgia, or headache occurring as manifestation of myocardial ischemia, has only recently been recognized as a distinct entity. In patients with known ischemic cardiopathy, its diagnosis depends on the presence of severe headache that is accompanied by nausea, worsened by physical exercise, and only ceases with nitrate administration. We report on two patients who met diagnostic crite...

Regional anesthesia of the head and neck is an effective method of obtaining surgical anesthesia for various procedures. Diagnostic and therapeutic head and neck blocks can also assist with the diagnosis and management of many chronic pain conditions, including headache, postherpetic neuralgia, and cancer pain in this region. Gamma knife surgery offers a unique approach to the management of ref...
