Everyone interested in industrial medicine realizes that, with the exception only of lead, benzol is at the present time the most serious of all the toxic substances used in industry. On this account it has seemed desirable to acquire a more intimate knowledge of the details of its action upon the body and particularly its immediate, acute effects. The present discussion will bear, therefore, n...

Previous work from our laboratory has demonstrated that the very low-frequency (VLF: 0-0.25 Hz) and low-frequency (LF: 0.25-0.8 Hz) power of arterial pressure variability (APV) are related to vasomotor reactivity in response to control signals from the rostral ventrolateral medulla (RVLM) via the sympathetic system in the rat. The present study evaluated the differences in the dynamic property ...

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...

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...

SUMMARY – Cerebral autoregulation is a mechanism that enables relatively constant cerebral blood flow during variations of cerebral perfusion pressure. The differences between cerebral blood flow at rest and after administration of a potent vasodilatory stimulus test such as hypercapnia reflect cerebral vasomotor reactivity defined as the vasodilation capacity of cerebral arterioles to external...

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...

It is believed that the sympathetic nervous system through its peripheral distribution, and possibly through central connections, exerts, at least' in part, a control on vasomotor tonus. In recent years, several series of experiments on dogs have been conducted in this laboratory to determine the course of vasomotor fibers as measured by thermic changes in the feet after arterial ligation and s...
