Conteúdo: | Summary.: The activity of alkaline phosphatase, acid phosphatase, glutamic-oxalacetic transaminase (GOT), lactic dehydrogenase (LDH), amylase, succinic dehydrogenase (SDH) and glucose-6-phosphate dehydrogenase (GPH) has been determined in the intercaruncular and caruncular areas of the endometrium during the follicular and luteal phases of the oestrous cycle and from 13 to 35 days of pregnancy in the ewe. The activities of the enzymes in the two areas of the endometrium were similar except that alkaline phosphatase activity was higher, and SDH lower, in the intercaruncular area. During the luteal phase of the oestrous cycle and during early pregnancy, alkaline and acid phosphatase activities increased in the intercaruncular and caruncular areas. Amylase and GOT values were also elevated in the caruncular area during early pregnancy. The level of LDH in the intercaruncular area of the endometrium was less during the luteal phase than during the follicular phase of the oestrous cycle. Enzyme activity was variable in the chorion, embryo and blastocoelic fluid. The only statistically significant change was a sharp rise in the acid phosphatase concentration of the blastocoelic fluid at 31 to 35 days of pregnancy.
