已知促甲状腺激素释放激素(TRH)具有刺激垂体释放 TSH、Prl 和 GH 的作用,除已充分证实的这些内分泌效应外,还有广泛分布于中枢神经系统内的三肽,在许多方面影响神经活动,提示神经三肽有可能充当神经介质。因为在体内 TRH 迅速被代谢,这已为大鼠和人血浆中它的半衰期相当短所证 Thyrotropin releasing hormone (TRH) is known to stimulate the release of TSH, Prl and GH from the pituitary gland. In addition to these endocrine effects, which are well documented, there are tripeptides widely distributed in the central nervous system and affect nerves in many ways Activity, suggesting that neurotrias may serve as nerve mediators. Because the TRH is rapidly metabolized in the body, it has been shown to be fairly short-lived in rat and human plasma
