Bilateral injections of the GABA(A) agonist muscimol into the lateral parabrachial nucleus (LPBN) disrupt satiety and induce strong ingestion of water and 0.3M NaCl in fluid-replete rats by mechanisms not completely clear. In the present study, we investigated the effects of the blockade of central muscarinic cholinergic receptors with atropine injected intracerebroventricularly (i.c.v.) on 0.3...

The brain circuits underlying tics in Tourette׳s syndrome (TS) are unknown but thought to involve cortico/amygdalo-striato-thalamo-cortical (CSTC) loop hyperactivity. We previously engineered a transgenic mouse "circuit model" of TS by expressing an artificial neuropotentiating transgene (encoding the cAMP-elevating, intracellular A1 subunit of cholera toxin) within a small population of dopami...

Hypertension is very prevalent in chronic kidney disease and critical for its prognosis. Sympathoexcitation and oxidative stress have been demonstrated to be involved in chronic kidney disease. We have shown previously that sympathoexcitation by brain oxidative stress mediates arterial pressure elevation in the salt-sensitive hypertension model, Dahl salt-sensitive rats. Thus, we investigated w...

The management of patients with uncontrolled arterial hypertension in real clinical practice remains a difficult task, despite the impressive arsenal antihypertensive drugs. In most cases, correction medical therapy and lifestyle modification this group can achieve success treatment, but some target levels blood pressure (AH) cannot be achieved. Aim. To assess incidence true resistant hypertens...

Phenylpropanolamine (dl-norephedrine) was one of the most widely used therapeutic agents to act on the sympathetic nervous system. Because of concerns regarding incidents of stroke, its use as a nasal decongestant was discontinued. Although considered an alpha1-adrenergic agonist, the vascular adrenergic pharmacology of phenylpropanolamine was not fully characterized. Unlike most other circulat...

Sir, Essential hypertension resistant to treatment often warrants suitable investigations to exclude underlying secondary causes. Aldosterone renin ratio (ARR) is an effective diagnostic tool for detecting primary hyperaldosteronism among patients with presumed essential hypertension. Further confirmation of existing adrenal tumours or hyperplasia can be obtained with imaging studies such as hi...

Hypertension and Nephropathy A number of studies presented at the meeting gave insight into clinical and pathophysiological aspects of hypertension and nephropathy in patients with diabetes. Tarver-Carr et al. (abstract 783) reported 16-year follow-up analysis of 9,250 adults aged 30–74 in 1976–1980 who participated in the Second National Health and Nutrition Examination Survey (NHANES II). A t...

BACKGROUND Adequate and rational pharmacotherapy is an important element of rehabilitation of patients with myocardial infarction. Orders of the Ministry of Health of the Russian Federation, domestic and international guidelines, and scientific publications - all contain a complete algorithm for rational pharmacotherapy [1, 2]. These documents are based on the principles of evidence-based medic...

UK-14,304 [5-bromo-N-(4,5-dihydro-1H-imidazol-2-yl)-6-quinoxalinamine]-mediated vasodilator responses were studied on wire myograph-mounted mouse aorta to determine the cells involved, mechanisms of action, and subtypes of alpha(2)-adrenoceptors. In the presence of induced tone, UK-14,304 produced concentration-related vasodilatation that was abolished by rauwolscine, N(omega)-nitro-L-arginine ...
