Abstract:
:An equimolar mixture of 3H-E1-S2 and 14C-E1 was injected in one shot into the inferior vena cava near the heart of female Japanese monkey. Following the injection, blood was collected from the aortic arch at intervals of 15 s over a period of 10 min. The concentration of radioactivities in the whole blood and serum was measured. The metabolites were analyzed by DEAE-Sephadex A-25 column chromatography, enzyme hydrolysis, thin layer chromatography and paper chromatography. Both radioactivities of 3H-E1-S and 14C-E1 rapidly decreased in the first 90-s serum sample. The 3H/14C ratio in the 0-15-s serum sample was 5 times higher than the initial ratio of injected compounds. The radioactivities in the serum gradually decreased after 90 s of injection. The 3H/14C ratio in the pulmonary tissue was very low after collecting the final blood sample. This result shows that the most of 3H-E1-S passed through the lung and the larger part of 14C-E1 remained in the lung following injection of these materials. So, it is probable that E1-S is in a form to be carried in the general circulation.
