Glomerular filtration rate, renal blood flow and blood viscosity during and after diabetic coma.
IT HAS Ions been recognized that renal disturbances may develop during the course of a diabetic coma. But only a few attempts have been made to evaluate the nature and the cause of these changes. In a first approach to this problem, McCance and Widdowson found a decreased inulin clearance and low oreatinine/inulin and urea/inulin clearance ratios. Two years ago, we reported a case in which the ...
متن کاملThe Control of Renal Blood Flow and Glomerular Filtration in Normal Man.
This report is concerned with the effective renal blood flow and rate of glomerular filtration in normal man, as determined by the diodrast and inulin clearances (26) during diuresis and during the action of phlorizin, adrenin, caffeine, nitrite, and typhoid vaccine. The observations not only throw light on the action of these agents, but also afford information concerning the physiological con...
متن کاملGlomerular Filtration Rate and Renal Functional Reserve
Glomerular filtration rate (GFR) is usually accepted as the best overall index of kidney function in health and disease. Normal GFR varies according to age, sex, and body size. In young adults it is approximately 120-130ml/ min/1.73 m2 and declines with age1. A decrease in GFR precedes the onset of clinical kidney failure; therefore, a persistently reduced GFR is a specific indication of chroni...
متن کاملChanges in renal blood flow, extraction of inulin, glomerular filtration rate, tissue pressure and urine flow with acute alterations of renal artery blood pressure.
I N A PREVIOUS publication (I) it was reported that acute stimulation of the renal nerves in the anesthetized dog caused reductions in renal blood flow (measured directly by a rotameter), the extraction of inulin (filtration fraction), glomerular titration rate, extraction of Diodrast, and urine flow. The findings indicated that the effects of nerve stimulation were primarily those attributable...
متن کاملRenal Handling of Hemoglobin I . Glomerular Filtration
During a severe hemolytic process, circulating free hemoglobin readily passes through the renal glomeruli. Filtered hemoglobin is extensively taken up by the cells of the proximal tubule (1, 2). When the absorbtive capacity of these cells is exceeded, hemoglobinuria ensues. The permeability of glomeruli, and presumably of other capillaries, for hemoglobin is considerably greater than for albumi...
