Kety-Schmidt method (medicine)


Kety-Schmidt method


A method for measuring organ blood flow first applied to the brain in 1944 by C. F. Schmidt and S. S. Kety. A chemically inert indicator gas is equilibrated with the tissue of the organ of interest and the rate of disappearance from the organ is measured. Blood flow is calculated on the assumption that the tissue and venous blood concentrations of the indicator gas are in diffusion equilibrium at all blood flow rates and that the rate of disappearance of the indicator from the tissue is a function of how much is in the tissue at any time, i.e., it is assumed to be an exponential disappearance.


aspartokinase homoserine dehydrogenase (medicine)


aspartokinase homoserine dehydrogenase


An enzyme complex consisting of aspartokinase, and homoserine dehydrogenase, The complex has been isolated from e. Coli and consists of four identical subunits with a molecular weight of 85,000. The enzyme complex is involved in the biosynthesis of amino acids of the aspartate family.
