('hlorothiazide decreases plasma volume, heart size, and cardiac output. The oligeamii stimulates vasomotor tone; this tends to maintain arterial pressure because chronic arterial hypertension is characteristically self-sustaining and homeostatic. This oligenmic stimulation of vasomotor tone results in increased sensitivity to the antihypertensivQe effect of drugs depressing or blocking vasomot...

Cerebral chemical vasomotor reactivity and autoregulation were tested in normal baboons before and after the intravenous or intravertebral infusion of atropine sulfate (0.02 mg/kg). Atropine did not appreciably effect autoregulatory response, but intravertebral injection suppressed the increase of cerebral blood flow (CBF) by inhalation of 5% CO2 and enhanced the decrease of CEF induced by hype...

Nasal compliance is a measure related to the blood volume in the nasal mucosa. The objective of this study was to better understand the vascular response in vasomotor rhinitis by measuring nasal cross-sectional area and nasal compliance before and after mucosal decongestion in 10 patients with vasomotor rhinitis compared with 10 healthy subjects. Nasal compliance was inferred by measuring nasal...

Many patients have nasal syndromes that are nonallergic and noninfectious and not caused by mechanical or anatomic abnormalities. There are at least 8 recognized nonallergic rhinitis syndromes: drug-induced rhinitis including rhinitis medicamentosa, gustatory rhinitis, hormonally induced rhinitis including the rhinitis of pregnancy, nonallergic rhinitis with eosinophilia syndrome, senile rhinit...

In the ongoing debate about migraine pathogenesis it is crucial whether vascular factors are of primary importance or the blood vessels are just ‘bystanders’. In Edward Liveing’s the first monograph on migraine entitled ‘On Megrim, Sick-headache, and Some Allied Disorders: A Contribution to the Pathology of Nerve-Storms’ (1) he proposed the neural theory of migraine, ascribing the problem to ‘d...

• establishing the role of the pancreas in controlling digestion, • determining the glycogenic function of the liver (which later helped understand the critical roles played by glucose and insulin in regulating vital bodily processes), and • demonstrating that nerves could either expand or constrict blood vessels, a breakthrough that helped understand the vasomotor system (vaso refers to blood ...

BACKGROUND Herbal supplements are widely used for vasomotor symptoms. OBJECTIVE To test the efficacy of 3 herbal regimens and hormone therapy for relief of vasomotor symptoms compared with placebo. DESIGN 1-year randomized, double-blind, placebo-controlled trial conducted from May 2001 to September 2004. SETTING Group Health, Washington State. PARTICIPANTS 351 women age 45 to 55 years w...

introduction: menopause is the most important event in middle-age. women, in this period, face several changes. vasomotor symptoms and skin changes are prevalent in the middle-age. this study, mainly, was performed identifying the vasomotor symptoms and skin changes in menopausal women. materials and methods: study sample was consisted of 150 women who have visited the healthcare centers, exper...

ABSTRACT Due to hormonal changes during menopause, various clinical symptoms arise in menopausal women including vasomotor symptoms. Exercise is one of the useful interventions deal with However, trials potential effectiveness exercise still require further research. The purpose this narrative review identify and summarize variety that can be used as an intervention effective against climacteri...

BACKGROUND Despite a nonobstructive coronary angiogram, many patients may still have an abnormal coronary vasomotor response to provocation and to myocardial demand during stress. The ability of noninvasive stress tests to predict coronary vasomotor dysfunction in patients with nonobstructive coronary artery disease is unknown. METHODS AND RESULTS All patients with nonobstructive coronary art...
