Popis: | The rate of disappearance from plasma and tissue localization of radioactivity were determined in rabbits following intravenous injections of radioiodinated human growth hormone (HGH*), and radioiodinated human serum albumin (HSA*). Tissue localization of radioactivity after Nal131 injection was also examined. HGH* was quickly cleared from the blood; during the extremely rapid initial period (between 2 and 10 minutes), the concentration of trichloroacetic acid precipitable plasma radioactivity fell by 61 %. For the interval 10 to 60 minutes, mean half-time of disappearance of 17.6 ±1.8 minutes (standard error) was determined in a group of 11 rabbits. Half-time of disappearance did not differ in young as compared with old animals. Listed in decreasing order, the tissue radioactivity concentrations at 90 minutes were: kidney, liver, lung, spleen, skin, adrenal, testis, intestine, marrow, pancreas, skeletal muscle fat and cerebral cortex. Substantial proportions of the radioactivity found in the liver and ki... |
