13. Antinociceptive effect on mice of the hydroalcoholic fraction and (-) epicatechin obtained from Combretum leprosum Mart & Eich
Previous studies on Combretum leprosum, a tree growing in the Northeastern states of Brazil, have shown antinociceptive effects of the ethanol extract of its leaves and bark, but studies examining its constituents are rare. The objective of this study was to evaluate the antinociceptive effect of the hydroalcoholic fraction (HF) of one of its constituents, t

14. Benign prostatic hyperplasia: clinical treatment can complicate cataract surgery
PURPOSE: To investigate the effects of alpha-1 adrenergic receptor antagonists for the treatment of benign prostatic hyperplasia (BPH) regarding potential risks of complications in the setting of cataract surgery. AIM: To address recommendations, optimal control therapy, voiding symptoms and safety within the setting of cataract surgery. MATERIALS AND METHOD

15. The role of central mechanisms in the anti-inflammatory effect of amitriptyline on carrageenan-induced paw edema in rats
OBJECTIVE: The present study was designed to further investigate the effect of amitriptyline, a classical tricyclic antidepressant, on carrageenan-induced paw edema in rats. METHODS: First, amitriptyline was administered intraperitoneally (i.p.) at doses of 20, 40 and 80 mg kg-1, 30 min before subplantar injection of carrageenan. Second, amitriptyline was gi

16. Estudo comparativo do uso de Medetomidina e Xilazina em gatos e sua reversão com Atipamezole / Comparative study of the use of Medetomidine and Xilazine in cats and its reversion with Atipamezole
The medetomidine is sedative and analgesic of the group of the a2 adrenergic agonist approved for dogs and cats, described now as more potent than the xylazine, an old agonist a2 adrenergic of veterinary use. The main difference among those two agonists is the selectivity to the receptors a2-adrenergics, being the medetomidine considered more selective, chec

17. Efeitos da associação entre treinamento físico e tratamento farmacológico com -bloqueadores sobre a cardiomiopatia induzida por hiperatividade simpática em camundongos / Effects of the association between exercise training and - blockers in a genetic model of sympathetic hyperactivity induced heart failure in mice
Adicionalmente às alterações estruturais e funcionais observadas na insuficiência cardíaca (IC), as alterações na dinâmica do Ca2+ intracelular apresentam uma relação negativa com a contratilidade e função cardíaca. Para evitar a progressão da IC, o tratamento desta síndrome, conta atualmente com intervenções multifatoriais, incluindo a tera

18. O papel do betabloqueador na miocardiopatia chagásica experimental: avaliação morfo-funcional / The role of betablockade on experimental chagasic cardiomyopathy: morpho-functional evaluation
A doença de Chagas, descrita há quase 100 anos por Carlos Chagas, continua sendo um problema de saúde pública na América Latina, com 15 milhões de infectados e 28 milhões de indivíduos susceptíveis. Vários mecanismos fisiopatológicos foram propostos para a progressão da miocardiopatia chagásica crônica, entre eles a denervação simpática. O u

19. Efeito do tratamento com benazepril e carvedilol administrado de forma isolada e em associação com treinamento físico supervisionado sobre a evolução clínica de cães com insuficiência mitral crônica naturalmente adquirida / Effect of benazepril and carvedilol treatment alone and in association with a supervised physical training in the development of naturally acquired chronic mitral valve regurgitation in dogs
INTRODUCTION: Sympathetic activation is present in patients having chronic mitral valve regurgitation even in asymptomatic ones. However, the effect of beta- blockers and a physical training program to modulate this sympathetic activation during this valve disease is unknown. The objective of this study has been to evaluate the effect of carvedilol and a phy

20. Efeito da terapia com Beta-bloqueadores em camundongos com deleção dos receptores alpha 2A/alpha 2C adrenérgicos / Effects of b- adrenergic antagonist therapy in mice lacking a 2A/a 2C adrenergic receptors
We have recently reported that disruption for both a2A ?and a2C adrenergic receptor subtypes in mice (KO) leads to sympathetic hyperactivity with evidence of heart failure (HF) by the age of 7 months. These mice provide a model system for evaluating the efficiency among different ?- adrenergic antagonists (BB) for HF therapy. In the present study, we evaluat

21. "Procedimentos odontológicos em pacientes hipertensos com ou sem o uso de anestésico local prilocaína associada ou não ao vasoconstritor felipressina" / Dental procedures in hypertensive patients with or without the use of the local anesthetic prilocaine associated or not to the vasoconstrictor felypressin
The objective of this study was to investigate the behavior of blood pressure and the role of anxiety during dental treatment of hypertensive patients. An evaluation was made of sixty-five hypertensive patients (blood pressure = 140/90 mm Hg) under anti-hypertensive treatment were evaluated by the IDATE anxiety test (n = 34), blood pressure measurements 2/2

22. Efeitos da injeção de moxonidina no controle da ingestão de sódio e regulação cardiovascular.
Deficit of water and sodium in the body is detected by receptors located in different parts of the body. These receptors or hormones signalize to specific areas in the brain that control renal responses and water and sodium intake. Among these areas are: organum vasculosum of the lamina terminalis (OVLT), subfornical organ (SFO), anteroventral third ventricl

23. Adrenoceptors of the medial septal area modulate water intake and renal excretory function induced by central administration of angiotensin II
We investigated the role of a-adrenergic antagonists and clonidine injected into the medial septal area (MSA) on water intake and the decrease in Na+, K+ and urine elicited by ANGII injection into the third ventricle (3rdV). Male Holtzman rats with stainless steel cannulas implanted into the 3rdV and MSA were used. ANGII (12 nmol/µl) increased water intake

24. Sensibilidade a agonistas [beta]-adrenergicos em atrio esquerdo isolado de ratos submetidos a estresse
Following foot shock stress white adipocytes and right atria from male and right atria from female rats sacrificed at diestrous, are supersensitive to the chronotropic effect of isoprenaline. Right atria from female rats are also subsensitive to noradrenaline. In the present study, we investigated whether the inotropic response to B-adrenergic agonists was a
