1. Sistema colinérgico central modula os ajustes dos sistemas cardiovascular e termorregulatório induzidos pelo exercício físico até a fadiga
ABSTRACT The purpose of this study was to verify if the cardiovascular and thermoregulatory adjustments mediated by central cholinergic receptors and peripheral cathecolamines during the physical exercise until fatigue. Wistar rats weighting 278 ± 5 g, were submitted to bilateral adrenodemedullation (ADM) or sham (SHAM) surgery. After recovery, the animals

2. Tirosyne hydroxilase as a marker of sympathetic drive within skeletal muscle and renal arterioles of normotensive rats: effects of physical training. / Tirosina hidroxilase como marcador da atividade simpática em artérias musculares esqueléticas e renais de ratos normotensos: efeitos do treinamento fisico.
Exercise training (T) does not reduce pressure in normotensive, but causes peripheral and central adjustments on cardiovascular system, mediated by autonomic nervous system. In this study we investigated whether T (55% maximal exercise capacity) is able to change vascular sympathetic drive to skeletal muscle (locomotor, non-locomotor), kidney and adrenals, u

3. Participação do sistema opioidérgico e dos glicocorticóides nas alterações comportamentais e da imunidade inata induzidas na prole pelo estresse pré-natal / Role of opioidergic system and glicocorticoids on behavior and innate immunity alterations induced by prenatal stress
Devido ao seu rápido crescimento, o feto é particularmente vulnerável a insultos e modificações no milieu hormonal. Este fato sugere que situações adversas experimentadas pela mãe grávida podem alterar o desenvolvimento e a saúde criança. Em vista das dificuldades metodológicas de se investigar o impacto do estresse pré-natal sobre o desenvolvim

4. Use of bupivacaine alone and associated to fentanyl and sufentanil in epidural anaesthesia in female dogs / Uso da bupivacaína isolada e associada ao fentanil e sufentanil em anestesia epidural em cadelas
Potent opioids such as fentanyl and sufentanil, althought largely used in dogs, are rarely employed at the epidural space on this species. The aim of the present study was to compare the cardiovascular and systemics effects, as well as the analgesic action on the post operative period of epidural anaesthesia performed with bupivacaine alone or associated wit

5. Influencia do sexo e das fases do ciclo estral sobre a reação de estresse em ratos
We studied the influence of sex and estrous cyc1e on the response of rats to swimming stress, at 30°C. The sensitivity to cathecolamines of isolated right atria and corticosterone plasma levels on male rats and female rats at estrus or diestrus were analysed after one swimming session of 5, 15, 30 or 50 min (single stress) or after three sessions of 5, 15 a
