前言虽然乳腺在生长、功能和萎退过程中形态上的变化是很大的(姚曾序、顾国彦,1957),可是和形态变化相伴随的化学和生物化学变化却研究得少。关于碱性磷酸酶(以下简称 AKP)方面,Kay(1925),Folley 和 Kay(1935)最早证明牛、羊和豚鼠乳腺含有相当量的这种酶。以后 Folley 和 Greenbaum(1947)进一步用生化方法研究了大鼠在怀
Although the morphological changes in mammary glands during growth, function, and wilting (Yao Zengxu, Gu Guoyan, 1957) are prevalent, the chemical and biochemical changes associated with morphological changes have been less studied. Kay (1925), Folley and Kay (1935) first demonstrated that cattle, sheep, and guinea pig mammary glands contain considerable amounts of this enzyme with regard to alkaline phosphatase (AKP). Later Folley and Greenbaum (1947) further biochemical methods studied in rats
