説明
The larvae of Rhacophorus schlegelii were treated with 0.033% thiourea solution, 0.033% thiourea+0.005% PHP solution, or 0.005% PHP solution, and the infl uences of these treatments on the hypophyses, thyroid glands and gonads were observed.From these results it is emphatically suggested that the levels of secretion of anterior-hypophyseal hormones are influenced by PHP treatment, and consequently the oversecretion of thyroid stimulating hormone does not occur in spite of thiourea treatment, and not only the degree but the direction of the gonadal differentiation may be influenced by the unusual secretion of anterior-hypophyseal hormones.
