ANÁLISE DO PERFIL DOS PROFISSIONAIS DE SAÚDE BUCAL DA SECRETARIA MUNICIPAL DE SAÚDE DE CURITIBA NA ABORDAGEM AO ADOLESCENTE

This study was accomplished with 202 buccal health professionals from 30 Health Units of Curitiba. The professionals’ profile were analyzed through questionnaires in the attendance of adolescents, concerning their participation in educational activities on buccal health and other subjects. The approach used by such professionals concerning the adolescent was also analyzed, as well as the perception of their own knowledge on the same topic. The results demostrated that the professionals who act along with the Family Health Program, participate more actively in educational activities with adolescents and also approach more themes besides buccal health, when compared with those from the Basic Unit of health.Este estudio fue realizado con 202 profesionales de equipos de Salud Bucal de 30 Postas que pertenecen al Departamento de Salud de la Municipalidad de Curitiba. A través de cuestionarios fue analizado el perfil de estos profesionales, en el abordaje al adolescente, ya sea en la participación de actividades educacionales con enfoco para la salud bucal y otros temas. También fue analizada la forma de abordaje de estos profesionales frente a los adolescentes, la percepción que estos profesionales tienen sobre su conocimiento con la misma y su visión acerca del conocimiento que el equipo de salud bucal posee. Los resultados muestran que los profesionales que actúan en Postas que tienen el Programa de Salud de la Familia, son más actuantes en actividades educacionales con los adolescentes y además, otros temas son abordados fuera los de salud bucal, cuando comparados con los de Postas Básicas.Este estudo foi realizado com 202 profissionais das equipes de Saúde Bucal de 30 Unidades de Saúde da Secretaria Municipal de Saúde de Curitiba. Através de questionários, analisou-se o perfil desses profissionais, na abordagem ao adolescente, quanto à participação em atividades educativas com enfoque em saúde bucal e outros temas. Foram analisados também a forma de abordagem e o conhecimento que esses profissionais possuem para assistir os adolescentes e sua visão sobre o conhecimento que a equipe de saúde bucal possui para prestar esta assistência. Os resultados demostraram que os profissionais que atuam em Unidade de Saúde (UBSF) com Programa de Saúde da Família, já implantado, participam mais de atividades educativas com adolescentes e abordam outros temas além de saúde bucal, quando comparados com os das Unidades Básicas de Saúde (USB)

Chronic social stress increases nitric oxide-dependent vasorelaxation in normotensive rats

The aim of this study was to examine oxidative load and endothelium-dependent vasorelaxation in the serotonin pre-constricted femoral artery (FA) of Wistar-Kyoto (WKY) rats exposed to chronic social stress produced by crowding in the presence or absence of ascorbic acid (AsA) in working solution. Adult male rats were randomly divided into control (living space: 480 cm2/rat) or stressed (living space: 200 cm2/rat) groups for 8 weeks. Blood pressure and heart rate, determined using tail-cuff plethysmography, were not influenced by stress vs. control. Conjugated dienes (CD) and concentrations of thiobarbituric acid-reactive substances (TBARS) were measured in the left ventricle and liver (for assessment of oxidative load) and were found unchanged by chronic crowding. The nitric oxide (NO)-dependent component of endothelium-dependent relaxation was investigated in the FA using a wire myograph. In both the presence and absence of AsA, acetylcholine-induced relaxation of the FA of stressed rats significantly exceeded that of the controls, which was associated with an increase of the NO-dependent component. In conclusion, the data showed that chronic crowding did not produce oxidative stress in the organs investigated and indicate that elevation of NO production during chronic stress is an important way of adaptation, which may prevent normotensive rats from the development of stress-induced hypertension

The sympathetic adrenomedullary system, but not the hypothalamic-pituitary-adrenal axis, participates in aorta adaptive response to stress: nitric oxide involvement

Stress induced a decrease in the reactivity of the aorta to noradrenaline (NA), as a consequence of an endothelial nitric oxide (NO) system hyperactivity. The main characteristic of the stress response is activation of the hypothalamic-pituitary-adrenal (HPA) axis and sympathetic adrenomedullary (SA) system. The participation of the HPA axis and SA system in the decreased reactivity to NA in the aorta of rats exposed to 4-h immobilization was investigated. Concentration-response relationships for NA were obtained in the aorta, with and without endothelium, isolated from normal and stressed rats, following these procedures: (1) in the absence and presence of L-NAME; (2) after adrenalectomy (ADX) or not, in the absence or presence of L-NAME; (3) ADX rats treated or not with corticosterone; (4) ADX associated with stress; and (5) treated or not with reserpine. The reactivity of aorta without endothelium was unaffected by the procedures. The reactivity of aorta with endothelium was decreased by either stress or ADX. This effect was reversed by both L-NAME and corticosterone. ADX did not potentiate the decrease in the aorta reactivity induced by stress. Reserpine did not change the reactivity of aorta with endothelium from normal rats, but prevented the decrease in reactivity induced by stress. It is concluded that the HPA axis participates in endothelium-dependent modulation of aorta reactivity in normal conditions and that thr SA system participates in hyperactivity of the endothelial NO-system induced by stress, which is responsible for the decreased aorta reactivity to NA.
