The flow rate of portal plasma was measured during hypothalamo-hypophysial portal sampling in the rat using a modified Worthington-Fink technique. In rats rendered hypothyroid with propylthiouracil, there was a significant 140% increase in portal plasma flow. Median eminence stimulation also increased portal plasma flow by 41%. Orchidectomy and adrenalectomy had no effects on plasma flow. Modification of flow rate in the hypothalamo-hypophysial vascular bed may represent a further mechanism involved in the control of pituitary function.
采用改良的沃辛顿-芬克技术，在大鼠下丘脑-垂体门脉采样期间测量门脉血浆流速。在用丙硫氧嘧啶使大鼠甲状腺功能减退后，门脉血浆流速显著增加了140%。正中隆起刺激也使门脉血浆流速增加了41%。睾丸切除术和肾上腺切除术对血浆流速无影响。下丘脑-垂体血管床流速的改变可能是参与垂体功能调控的另一种机制。
