[Organ hematocrit and determining the blood content of tissue homogenates].

The authors determined the mean normal values of organ homogenates and their significance in evaluating blood amount, contained in the organs. They used radioisotope method with two kers 131 J and 51Cz for determining organ hematocrit. The hematocrit values of the organ blood differed significantly from the venous hematocrit as the values of the spleen were higher, but those of liver, kideny, cerebrum, testis and skeletal muscles-lower. On the basis of these data they proposed to apply respective correction factors, checking the differences between venous and organ hematocrits, when the amount of blood in single organs, determined by hemoglobin content, was estimated. The validity of this correction was illustrated by experimental results.
