Alpha-melanocyte-stimulating hormone (alpha-MSH), one of several peptide hormones originating in the intermediate lobe of the pituitary as proopiomelanocortin, was discovered in bovine pituitary intraglandular colloid by using radioimmunoassay. The quantity of alpha-MSH varied from 5 to 368 micrograms/mg protein in the three pools. The importance of this finding is discussed in light of the possibility that the colloid is a transport medium for alpha-MSH and other intermediate lobe hormones.
α-黑素细胞刺激素（α-MSH）是源自垂体中间叶的几种肽类激素之一，作为阿片促黑素皮质素原，通过放射免疫测定法在牛垂体腺内胶体中被发现。在三个样本中，α-MSH的含量在每毫克蛋白质5至368微克之间变化。鉴于胶体可能是α-MSH和其他中间叶激素的运输介质，对这一发现的重要性进行了讨论。
