Plasma and Blood Volumes of Mouse Organs, As Determined with Radioactive Iodoproteins.

Summary The plasma and blood volumes of mice and of various mouse organs were determined by injecting mice with a protein iodinated with iodine containing tracer quantities of radioactive iodine, and determining the amount of radioactivity present in the various organs. The average plasma and blood volumes of the mice were found to be 6.7 ml and 12.7 ml per 100 g of body weight, respectively. The average plasma volume in ml per 100 g of wet tissue for the brain was 1.6; kidney, 19.1; liver, 20.2; lung, 23.9; small intestine, 5.0; spleen, 9.2; submaxillary gland, 5.9; testes, 3.4.
