A Comparison of the Method of Excretion of Neutral Red and Phenol Red by the Mammalian Kidney
A direct examination with the method of perfusion of the excretion by the frog's kidney of phenol red and neutral red has shown that the dyes are eliminated in different manners as a result of different mechanisms. The former is excreted in much the greater part by the glomeruli; the latter by the tubules. Urea is excreted in a manner similar to phenol red. The indirect examination of the funct...
متن کاملA Comparison of the Manner of Excretion of Neutral Red and Phenol Red by the Frog's Kidney
1. Phenol red and neutral red are excreted by the perfused frog's kidney by different routes. 2. Phenol red is excreted chiefly through the glomerulus, neutral red through the tubules. 3. Some slight excretion of each of these dyes by the converse mechanism is possible, though there is no evidence in our experiments that necessitates such a conclusion. 4. The importance of methods leading to th...
متن کاملThe Phenol Red Clearance in Normal Man.
Although phenol red, introduced by Rowntree and Geraghty (6) in 1912, has been widely used in man as an empirical renal function test, the excretion of this substance relative to its concentration in the plasma has been examined in only one instance. MacKay (1930) injected one gram intravenously and calculated the Addis excretory ratio in three successive periods when the plasma level was 5.80,...
متن کاملAbsorbance signals from resting frog skeletal muscle fibers injected with the pH indicator dye, phenol red
Singly dissected twitch fibers from frog muscle were studied on an optical bench apparatus after micro-injection with the pH indicator dye, phenol red. Dye-related absorbances in myoplasm, denoted by A0(lambda) and A90(lambda), were estimated as a function of wavelength lambda (450 nm less than or equal to lambda less than or equal to 640 nm) with light polarized parallel (0 degrees) and perpen...
متن کاملEstimating microsatellite based genetic diversity in Rhode Island Red chicken
This study aimed to estimate microsatellite based genetic diversity in two lines (the selected RIRS and control line RIRC) of Rhode Island Red (RIR) chicken. Genomic DNA of 24 randomly selected birds maintained at Central Avian Research Institute (India) and 24 microsatellite markers were used. Microsatellite alleles were determined on 6% urea-PAGE, recorded using GelDoc system and the samples ...
