... concentrations were determined by specific radioimmunoassay. 3. Plasma AM concentrations did not increase with anaesthesia or surgery ( n = 9). Plasma AM concentrations gradually increased during cardiopulmonary bypass and after pulmonary reperfusion. After pulmonary reperfusion, plasma AM concentrations...

...Eva Selldén; Robert Bränstróam; Tomas Brundin 1. Intravenous infusion of amino acid mixtures stimulates human oxidative heat production more effectively under general anaesthesia than in the unanaesthetized state. To analyse the splanchnic and extra-splanchnic regional distribution...

...EVA Selldén; Tomas Brundin; John Wahren 1. Intravenous infusion of amino acids stimulates energy expenditure and heat accumulation in normal man. To find out whether such stimulation also occurs during general anaesthesia, thermogenesis was measured in 21 patients before, during and after...

...R. J. C. Hall; I. R. Cameron 1. Pentobarbitone anaesthesia, in rabbits, produces (i) hypokalaemia, (ii) increased intracellular potassium and reduced intracellular sodium in cardiac and skeletal muscle. 2. These changes suggest that the hypokalaemia which accompanies anaesthesia results from...

...B. M. Koeppen; A. I. Katz; M. D. Lindheimer 1. The effect of sodium pentobarbital and Inactin anaesthesia on renal haemodynamics in the rat was evaluated with radioactive microspheres 15 μm in diameter. 2. Both anaesthetic agents caused substantial decrements in total renal blood flow (sodium...

... anaesthesia and starvation on hepatic transport of dibromosulphthalein was also studied. The influence of bile salts on the hepatic transport process was investigated by interruption of the enterohepatic circulation. 2. Maximal biliary transport of dibromosulphthalein was subject to circadian variations...

... renal blood flow fell by 25%, this fall being confined to the superficial renal cortex. 4. In rabbits subject to haemorrhage under pentobarbitone anaesthesia renal blood flow fell by a further 23% when compared with the conscious bled rabbits. This reduction in blood flow was confined to the superficial...

... in response to either tactile or chemical (citric acid aerosol) stimulation was invariably abolished. The Hering—Breuer inflation reflex was impaired, but this was not associated with any change in resting ventilation. The V̇ E /CO 2 response was enhanced after aerosol anaesthesia; subjects felt...

...Madeleine Vincent; Jeanne Dupont; J. Sassard 1. Strains of spontaneously hypertensive and normotensive rats were selected by repeated inbreeding. 2. Brief ether anaesthesia was shown to produce a two- to three-fold increase in plasma renin activity in both strains. 3. Plasma renin activity...
