The periodic acid-Schiff (PAS) reaction and tests for glycogen phosphorylase, oxidative enzymes and acid-stable and alkali-stable adenosine triphophatase (ATPase) were used to determine the degree of histochemical differentiation between myofibres of sartorius muscles from neonatal piglets. Within 24 h of birth, the ratio of myofibres with acid-stable ATPase to those with acid-labile ATPase was 1:21-0. By 10 days the ratio had changed to 1:5-2. Mean minimum myofibre diameters (all histochemical types combined) increased steadily after birth although diameters of myofibres with acid-stable ATPase showed no increase until 6 days. By 10 days, consistent differentiation was observed with the alkali-stable ATPase and glycogen phosphorylase reactions but not with the PAS reaction. During the 10 day neonatal period, all types of myofibres contained large or moderate numbers of mitochondria.
采用过碘酸 - 希夫（PAS）反应以及糖原磷酸化酶、氧化酶和酸稳定及碱稳定三磷酸腺苷酶（ATP酶）检测，来确定新生仔猪缝匠肌肌纤维之间的组织化学分化程度。出生后24小时内，酸稳定ATP酶阳性肌纤维与酸不稳定ATP酶阳性肌纤维的比例为1:21 - 0。到10日龄时，该比例变为1:5 - 2。出生后，所有组织化学类型合并计算的平均最小肌纤维直径稳步增加，不过酸稳定ATP酶阳性肌纤维的直径直到6日龄才开始增加。到10日龄时，碱稳定ATP酶和糖原磷酸化酶反应呈现出一致的分化，但PAS反应未出现。在新生期的10天里，所有类型的肌纤维都含有大量或中等数量的线粒体。
