13. Efeito da obesidade sobre a forÃa dos mÃsculos respiratÃrios e centro respiratÃrio
Background: The obesity affects many organs and systems of human body, prejudicing vital functions by immunologic, circulatory, hormonal and respiratory functions. On the respiratory system, obesity results in a reduction of lung volumes and flows. Also take a reduction on the respiratory compliance and an increment on the total respiratory resistance. Metho

14. Dopplerfluxometria das artérias renais: valores normais das velocidades sistólica e diastólica e do índice resistivo nas artérias renais principais
Dopplerfluxometry of renal arteries has been used to estimate renal perfusion in humans. The aim of this study was to use Dopplerfluxometry technique to calculate the resistive index of main renal arteries in dogs, measuring their systolic and diastolic blood flow velocities. Twenty (10 males, 10 females), adult mongrel dogs, were used in this study. The dog

15. Scintigraphy and Doppler ultrasonography for the evaluation of obstructive urinary calculi
Forty-seven patients with unilateral obstructive calculi (12 males and 35 females) were submitted to 99mTc-diethylene triamine pentaacetic acid (DTPA) or 99mTc-dimercaptosuccinic acid (DMSA) scans for assessment of renal function. The scans revealed unilateral functional deficit in 68 and 66% of the patients, respectively. A calculus size of 1.1 to 2.0 cm wa

16. Effects of lung volume and fatigue on evoked diaphragmatic phonomyogram in normal subjects.
BACKGROUND: A diaphragmatic phonomyogram (PMG) evoked by maximal phrenic nerve stimulation at end expiratory lung volume (FRC) has been previously described as a good index of changes in diaphragmatic contractility with fatigue. A study was undertaken to assess whether this conclusion could be extended to different lung volumes. METHODS: Diaphragmatic compou

17. Effect of intra-articular hyaluronan on pressure-flow relation across synovium in anaesthetized rabbits.
1. Hyaluronan is the major polysaccharide of synovial fluid, responsible for its high viscosity. The effect of hyaluronan on fluid transport across the synovial lining of the joint was investigated. Rate of fluid absorption from the joint cavity (Qs) was measured at intra-articular pressures (Pj) of up to 24 cmH2O in knees of anaesthetized rabbits, in the pr
