The decline in serum MT showed two distinct components following morning administration. Half-life of the initial component which probably represents rapid distribution into tissues...

... in animals which had persistence of pulsatile secretion of LH. Phenobarbital eliminated pulsatile secretion of LH transiently. Hypophysectomized rats displayed a striking decrease in plasma LH which could be resolved into two exponential components with half-lives of 16 and 70 min. The initial half-life...
