Succinate dehydrogenase (SDH), lactate dehydrogenase (LDH), glutamateoxaloacetate transaminase (GOT), and acid and alkaline phosphatase are present in ram, bull, dog, rabbit, and human semen but the concentrations differ from one species to another. Amylase is found in the semen of all these species except the ram, and glucose�6-phosphate dehydrogenase (GDH) in all except the bull.

Developing Rat

The oral mucosa of developing and mature rats was analyzed histochemically for regional enzyme differences. The following enzymes were studied: nonspecific alkaline phosphatase (alkpase), acid phosphatase (acidpase), 5'-nucleotidase (AMPase), adenosine triphosphatase (ATPase), succinate dehydrogenase (SDH), lactate dehydrogenase (LDH), and glucose-6-phosphate dehydrogenase (G-6-pDH). All enzymes were active in the oral mucosa, but regional as well as tissue variations were observed. Epithelium in all regions showed acidpase staining. Oxidoreductases were found in all regions with variations within the epithelium. The epithelium of specific regions stained for alkpase and AMPase, while adjacent epithelium did not. We suggest that the alkpase and AMPase activities are associated with specific functions of the epithelium in these regions.

SUMMARY Progesterone was secreted by hamster corpora lutea between days 1 and 15 of pregnancy; on day 14, the concentration in the peripheral plasma reached a maximum. A pronounced fall in luteal weight began on the day after parturition and the corpora lutea had virtually disappeared by days 4–5 post partum. The concentration of protein and the weights of the corpora lutea reached peak levels on days 12 and 14 respectively. The highest levels of luteal RNA were reached on days 12–13. The concentration of DNA in the corpora lutea was constant throughout pregnancy, indicating that hypertrophy rather than hyperplasia accounted for the increase in luteal weight. Luteal concentrations of cholesterol and its esters were unchanged between days 1 and 14 of pregnancy except for a significant decline in the level of cholesteryl ester on days 8 and 13. During the final stages of regression of the corpora lutea during lactation, the luteal concentrations of free and esterified cholesterol rose to three and ten times respectively, the values obtained on day 2 of pregnancy. A significant increase in the concentration of acid and alkaline phosphatase began on day 16 of pregnancy correlated with the onset of structural luteolysis. The activity of luteal glucose-6-phosphate dehydrogenase peaked on days 2 (comparable to the value on day 2 of the oestrous cycle) and 13 of pregnancy and day 3 of lactation. The high levels on these days may be associated either with luteal steroidogenesis during pregnancy or with lipid metabolism during the post-partum involutional phase. The activity of luteal 3β-hydroxysteroid dehydrogenase was relatively constant except for significant decreases on days 10 and 13 of pregnancy. The results indicate that the activities of all of the biochemical variables in the corpora lutea of pregnancy were highest between days 11 and 13.

Activity Of Enzymes

The activity of several enzymes has been measured in the endometrium, caruncles, and uterine rinsings of ewes at various stages of the oestrous cycle. Ewes were either allowed to cycle naturally or were synchronized by progestogenimpregnated sponges inserted into the vagina. Most (86%) of the progestogentreated ewes came into oestrus 2 or 3 days after removal of the sponges, and the uterus contained higher levels of amylase and alkaline phosphatase than did naturally cycling ewes. Amylase, succinate dehydrogenase, glutamate-oxaloacetate transaminase, acid and alkaline phosphatase activities were maximal during the luteal phase of the cycle. Endometrial alkaline phosphatase activity followed the growth and retrogression of the corpus luteum more closely than that of the other enzymes studied.

Histochemical Changes

ABSTRACT Acute changes in glucose-6-phosphate dehydrogenase and isocitrate dehydrogenase activity in the zona glomerulosa of the rat adrenal cortex were induced by peritoneal dialysis with 5 % glucose. Although less clear, the activity of 3β-ol-hydroxysteroid dehydrogenase also seemed to increase as well. No changes were seen in the activity of succinate dehydrogenase. Dialysis with 0.9 % NaCl had no effect on any of the enzymes investigated. The possible significance of these observations is discussed.
