Comparative study of glomerular filtration rate with diverse labelled agents.

Clearances of 113mIn-EDTA, or 99mTc -DTPA or 131I-iothalamate were compared with 3H-inulin simultaneously in rabbits or dogs. The classical plateau method was explored followed by a second slope in some instances or by the single shot procedure in others. A two-compartmental mathematical model was always employed to compare and calculate. The study suggests that the diverse agents tested are handled following similar homeostatic trends and values, although the intervening membranes may act upon them individually with diffusion rates that may vary in relation to each substance, in particular at a given time interval.

[Correlation between the biological half-life of tritiated water and the body surface area in man. Preliminary report].

The literature about the half-life of the tritiated water has shown a great variety from one specimen to another. In order to determine the influence of this variations upon metabolism, mass or body surface we studied 16 healthy subjects and one patient with renal failure. We founded that there is a good correlation between the body surface and the biological half-life of the tritiated water in humans. The correlation average was 1.02.

[Total water content in cardiac patients].

In the present study total body water was determined in a group of cardiac patients, using titriated water. The study was performed in a service of internal medicine of an important hospital in Mexico City. Of the 30 patients originally evaluated, only 23 could be considered cardiacs; of these 47.83% had an excess of water, 39.13% had a normal amount and 13.04% were dehidrated. The patients belonged to both sexes and their ages were anywhere between 14 and 82 years. Very often, other aliments or conditions were present which had a bearing on the total body water. The test is innocuous and the bother to the patient is minimal constituting a valuable auxiliary to the clinician.
