25. Avaliação de seis protocolos pré-anestésicos para anestesia epidural de caninos / Evaluation of six pre-anesthetic combinations to canine epidural anesthesia
Vários protocolos de pré-anestesia podem ser usados em esquemas de anestesia que incluam anestesia epidural. A disponibilidade de diferentes fármacos e combinações permite a escolha de um procedimento anestésico específico para cada paciente, dependendo do grau de risco anestésico e do temperamento do animal. A escolha do protocolo pré anestésico d

26. Efeitos da infusão profilática contínua de fenilefrina sobre a estratégia de redução da massa de anestésico local em pacientes submetidas à raquianestesia para cesariana. / Effects of prophylactic continuous infusion of phenylephrine on the strategic use of reduced dose of local anesthetics in elective cesarean patients undergoing spinal anesthesia.
Background: Reduced local anesthetic dose is used for minimizing hypotension changes related with spinal anesthesia for cesarean section, optimizing both maternal and fetal outcomes. This strategy can result in neuroaxial block failure. On the other hand, the higher doses associated with hypotension can be controlled with continuous prophylactic infusion of

27. Efeitos da obesidade no sistema calicreína-cininas: estudo dos receptores b1 e b2 de cininas em tecido adiposo humano e murino. / Obesity, Leptin and Renin-Angiotensin System: Role on blood pressure control and autonomic regulation in ob/ob and db/db mice.
The leptin deficient ob/ob mice are insulin resistant and obese. However, the control of blood pressure in this model is not well defined. The goal of this study was to evaluate the role of leptin and the renin-angiotensin system (RAS) in the cardiovascular abnormalities observed in obesity using a model lacking leptin. Leptin is a hormone related to metabol

28. Tonic and reflex cardiovascular autonomic control in trained-female rats
The effects of exercise training on cardiovascular and autonomic functions were investigated in female rats. After an aerobic exercise training period (treadmill: 5 days/week for 8 weeks), conscious female Wistar (2 to 3 months) sedentary (S, N = 7) or trained rats (T, N = 7) were cannulated for direct arterial pressure (AP) recording in the non-ovulatory ph

29. AvaliaÃÃo morfomÃtrica da regeneraÃÃo nervosa perifÃrica em animais desnutridos precocemente
The study evaluated the peripheral nerve regeneration in adult animals that were submitted to protein malnutrition during the period known as the critical window of development. We used 20 male rats, adult, Wistar line. During the period of lactation, parts of the mothers received diet hypoproteic (casein 8%) forming the group of malnourished pups (10 animal

30. Participation of the cholinergic system in the ethanol-induced suppression of paradoxical sleep in rats
Sleep disturbance is among the many consequences of ethanol abuse in both humans and rodents. Ethanol consumption can reduce REM or paradoxical sleep (PS) in humans and rats, respectively. The first aim of this study was to develop an animal model of ethanol-induced PS suppression. This model administered intragastrically (by gavage) to male Wistar rats (3 m

31. Parasympathetic dysfunction is associated with insulin resistance in fructose-fed female rats
The objective of the present study was to identify metabolic, cardiovascular and autonomic changes induced by fructose overload administered in the drinking water of rats for 8 weeks. Female Wistar rats (200-220 g) were divided into 2 groups: control (N = 8) and fructose-fed rats (N = 5; 100 mg/L fructose in drinking water for 8 weeks). The autonomic control

32. Ketamine anesthesia with S (+) to atropine and xylazine ASSOCIATED IN DOGS: EVALUATION heart and Serum / ANESTESIA COM CETAMINA S(+) ASSOCIADA À ATROPINA E XILAZINA EM CÃES: AVALIAÇÃO CARDÍACA E BIOQUÍMICA SÉRICA
Changes in physiological parameters of electrocardiography, echocardiography and biochemistry markers were evaluated in dogs anesthetized with different associations of atropine, xylazine and S-ketamine. Twenty three healthy female dogs randomly distributed in four groups named as GI-6, GII-6, GIII-6 and GIV-5 were treated respectively with atropine and S-ke

35. Importância da região AV3V e de mecanismos colinérgicos e angiotensinérgicos centrais para os efeitos cardiovasculares produzidos pela ativação da área rostroventrolateral do bulbo
Cardiovascular responses are integrated at different levels of the central nervous system (CNS). In the brainstem, there are different areas related to the cardiovascular control such as the rostral ventrolateral medulla (RVLM) that activates sympathetic pre-ganglionic neurons in the spinal cord (IML) inducing pressor response. Like glutamatergic activation,

36. Infusão contínua de xilazina ou dexmedetomidina em cadelas pré-tratadas ou não com atropina: alterações eletrocardiográficas.
Alpha-adrenergic agonist drugs were synthesized at the beginning of the sixties. These drugs cause analgesic, sedative, ansiolitic and simpatholitics effects. Their use is extensive in veterinary due to their sedative, analgesic and miorrelaxantes effects. Alpha-adrenergic agonists cause significant changes in the cardiopulmonary system. Bradicardy, arrhythm
