Effects of ergocornine and reserpine on tail resorption during metamorphosis in Bufo bufo japonicus tadpoles were studied. At prometamorphosis, ergocornine induced precocious tail resorption, while reserpine scarcely affected the tail size. At the climax of metamorphosis, ergocornine was almost ineffective in accelerating tail resorption, while reserpine was effective in inhibiting tail resorption. Since prolactin-like hormone is known to block the tail resorption induced by thyroid hormones, it was postulated that the release of the hormone is blocked by ergocornine during prometamorphosis and stimulated by reserpine during climax.
研究了麦角柯宁和利血平对日本蟾蜍蝌蚪变态过程中尾部吸收的影响。在变态前期，麦角柯宁诱导早熟的尾部吸收，而利血平几乎不影响尾部大小。在变态高峰期，麦角柯宁在加速尾部吸收方面几乎无效，而利血平在抑制尾部吸收方面有效。由于已知催乳素样激素会阻断甲状腺激素诱导的尾部吸收，因此推测该激素的释放在变态前期被麦角柯宁阻断，而在高峰期被利血平刺激。
