Alkaline phosphatase activity as well as lipid, polysaccharide, glycogen, and acid mucopolysaccharide levels in the uteri of 79 gilts were histochemically tested during the first three sexual cycles. Intra-cyclic alkaline phosphatase activity exhibited clearly pronounced variations in the surface epithelium, with maximum values reached in metoestrus, and moderate variations in the endometrial stroma, with maximum values reached in dioestrus. Cycle-dependent variations were recordable also from the glycogen and lipid levels in the surface and glandular epithelia and from the acid mucopolysaccharide levels in the endometrial stroma. The activity of alkaline phosphatase as well as the levels of glycogen and acid mucopolysaccharides during the first cycle still were lower than those in the second and third. Biochemical examinations of the endometrium revealed significant cycle-dependent variations in the activities of alkaline phosphatase, inorganic pyrophosphatase, and succinate-dehydrogenase as well as in the concentrations of soluble protein and glycogen, with maximum values being recordable on the tenth day of cycle. No significant intracyclic variations were recordable from the activities of acid phosphatase as well as of aspartate alanine-amino transferase.
在79头后备母猪的前三个性周期中，对其子宫中的碱性磷酸酶活性以及脂质、多糖、糖原和酸性粘多糖水平进行了组织化学检测。发情周期内，表面上皮中的碱性磷酸酶活性呈现出明显的变化，在间情期达到最大值，子宫内膜基质中的变化较为适中，在发情后期达到最大值。发情周期依赖性变化也可从表面和腺上皮中的糖原和脂质水平以及子宫内膜基质中的酸性粘多糖水平中记录到。第一个周期中碱性磷酸酶的活性以及糖原和酸性粘多糖的水平仍低于第二个和第三个周期。子宫内膜的生化检查显示，碱性磷酸酶、无机焦磷酸酶和琥珀酸脱氢酶的活性以及可溶性蛋白质和糖原的浓度存在明显的发情周期依赖性变化，在周期的第十天可记录到最大值。酸性磷酸酶以及天冬氨酸丙氨酸转氨酶的活性未记录到明显的发情周期内变化。
