متن کاملThyrotrophic hormone content of the pituitary of molting and laying hens.
In recent papers, Tanabe et al.(1956,1957) reported that no increase in the uptake of I131 by the thyroid was observed in molting hens as compared with laying hens,and no acceleration in the release of I131 as thyroid hormone from the thyroid of the hen was observed either in molting period or in pre-molting period. Further-more, it has been shown that thiouracil feeding does not prevent natura...
