近几年来对中枢神经内出现的生物活性肽及垂体蛋白质激素的研究有很大进展。这一方面要归之于对这些物质的提纯与合成方法的建立与完善,另一方面也是与免疫学实验方法的广泛应用有关。应用这些纯化了的物质对动物进行免疫虽然可以得到颇为专一的抗体,但是目前尚不能十分肯定用此法所 In recent years there has been great progress in the study of bioactive peptides and pituitary protein hormones in central nervous system. This is due, in part, to the establishment and improvement of methods for the purification and synthesis of these substances, on the one hand, and on the other hand to the extensive application of immunological methods. Although it is possible to obtain quite specific antibodies by applying these purified substances to animals, it is not yet quite certain that this method
