[Glycogen content and the activity of alkaline and acid phosphatase (ARP and AeP) lactate dehydrogenase (LDH) in the sow endometrium during the sexual cycle].
Biochemical indices were determined in 101 samples of endometrium taken from 16 praepubertal and 85 sexually mature gilts divided into four groups according to the stage of the cycle. On an average, glycogen content in praepubertal gilts was 3.354 mg/g-1 of fresh endometrium tissue, and in sexually mature sows 3.035 mg/g-1. A statistically and significantly higher value (4.066 mg:2.098 mg/g-1--P less than 0.01) was obtained in the luteal phase. Alkaline phosphatase showed a significantly higher level (P - less than 0.01) in sexually mature gilts than in praepubertal gilts (3291.2 mU.: :2457.7 mU). Reverse ratios were obtained (492.46 mU:687.8 mU.) in the content of acid phosphatase (P less than 0.01). In sexually mature sows the contents of AIP and AcP in endometrium were higher in the luteal phase (3624 mU. and 508.86 mU.:3085.7 mU. and 481.9 mU.). The differences between individual stages of the cycles were statistically insignificant (P less than 0.1). The content of lactate dehydrogenase (LDH) was slightly lower in praepubertal gilts than in mature sows (4.89 I.U.:526 I.U.). The highest content was found in late metestrus (7.682), and the lowest in sows in proestrus (4.494 I.U.). The difference was statistically highly significant (P less than 0.01). The role of these substances in endometrium and their regulation mechanisms are dealt with in discussion.
