13. Efeitos da estimulação nervosa elétrica transcutânea na vascularização placentária de ratas com restrição induzida ao fluxo uterino.
Introdução: Frente aos altos índices de morbimortalidade fetal relacionados a gestações complicadas por insuficiência placentária e restrição do crescimento intra-uterino e baseado em trabalhos que citam a Estimulação Nervosa Elétrica Transcutânea (TENS) como forma de tratamento da insuficiência placentária, o objetivo desse estudo foi avaliar

14. Repercussões imediatas nas provas de função pulmonar no pós-operatório de indivíduos com obesidade grau II e mórbida submetidos à cirurgia de redução gástrica por celiotomia ou videolaparoscopia
Obesity is the most common chronic disease in developed countries and is associated to the most severe and morbid clinical situations, including respiratory disturbances that can be aggravated by surgical techniques, increasing the hospitalar permanence. The gastric reduction has been considered, after 45 years of study, the only efficient and lasting method

16. Sobrecarga e restrição de sal na dieta durante a gestação em ratas Wistar: efeitos sobre o sistema renina-angiotensina, função renal, resistência à insulina e pressão arterial / Dietary salt overload or restriction during gestation in Wistar rats: effects on the renin-angiotensin system, renal function, insulin resistance and blood pressure
Diversos estudos epidemiológicos têm relacionado doenças na vida adulta, como diabetes tipo-2 e hipertensão, e ambiente inadequado durante a vida fetal. Fatores distintos relacionados aos hábitos alimentares, como ingestão de sal na dieta, podem ter impacto importante no período perinatal. Recentemente, demonstramos que dieta hipossódica (HO) durante

17. Urinary kallikrein and plasma renin activity as determinants of renal blood flow. The influence of race and dietary sodium intake.
We investigated the relationship of the kallikrein-kinin system and the renin-angiotensin system in the regulation of blood pressure, salt and water excretion, and renal blood flow. Normotensive and hypertensive black and white men were studied during unresticted sodium intake as well as on a 10-meq/day sodium intake; potassium intake was held constant throu

18. Defect in the sodium-modulated tissue responsiveness to angiotensin II in essential hypertension.
In normal subjects, dietary sodium intake modulates renovascular, adrenal, and pressor responses to infused angiotensin II (AII). To examine the hypothesis that this modulation is abnormal in some patients with essential hypertension, we studied 18 hypertensives and 9 normal subjects twice--during dietary sodium restriction and during loading. Paraaminohippu

19. The Effect of Chronic Sodium Loading and Sodium Restriction on Plasma Prostaglandin A, E and F Concentrations in Normal Humans
It has been suggested that prostaglandins may be involved in the control of sodium homeostasis. Prostaglandin A and prostaglandin E have been shown to increase renal blood flow and urinary sodium excretion and prostaglandin A has been shown to stimulate aldosterone release. The purpose of this study was to determine the effect of chronic sodium loading and s

20. Correlation of contractile dysfunction with oxidative energy production and tissue high energy phosphate stores during partial coronary flow disruption in rabbit heart.
The relationships between contractile function, myocardial oxygen consumption, and tissue high energy phosphate and lactate content were investigated during partial coronary flow disruption. The experimental preparation was an isolated, isovolumic retrograde blood-perfused rabbit heart. Both developed pressure (r = 0.94) and dp/dt (r = 0.95) exhibited strong

21. Reflex Cardiovascular Depression during Unilateral Lung Hyperinflation in the Dog
We have examined whether lung hyperinflation in the anesthetized dog reflexly depresses cardiac output, stroke volume, heart rate, and blood pressure and whether these changes persist for more than a minute. To eliminate any mechanical restriction to venous return and pulmonary blood flow during lung hyperinflation, a model was developed in which all pulmona

22. Ischaemic skeletal muscle hyperaemia in the anaesthetized cat: no contribution of A2A adenosine receptors.
1. The present study investigated the contribution of the A2A adenosine receptor subtype to the functional hyperaemia response evoked by muscle contraction in anaesthetized cats when muscle blood flow was limited. 2. Application of a stenosis reduced the hindlimb blood flow at rest from 9.67 +/- 1.80 to 5.53 +/- 0.91 ml min(-1) (kg body mass)(-1) and during

23. Gut endotoxin restriction prevents catabolic changes in glutamine metabolism after surgery in the bile duct-ligated rat.
OBJECTIVE: The objective of this study was to investigate the role of gut-derived endotoxemia in postoperative glutamine (GLN) metabolism of bile duct-ligated rats. SUMMARY BACKGROUND DATA: Postoperative complications in patients with obstructive jaundice are associated with gut-derived endotoxemia. In experimental endotoxemia, catabolic changes in GLN metab

24. The effects of chimeric cells following donor bone marrow infusions as detected by PCR-flow assays in kidney transplant recipients.
40 recipients of first cadaver kidney transplants were given perioperative donor vertebral bone marrow infusions (DBMC), compared with 100 controls who did not receive donor bone marrow. The immunosuppressive regimen included OKT3, Tacrolimus, and steroid maintenance therapy, and, in some patients, newly introduced mycophenolate mofetil. This report describe
