Phosphomonoesterases and Histamine in the Uterus of the Ewe During Early Pregnancy

Abstract

An attempt was made to assess whether histamine is involved in the regulation of sheep uterine endometrial acid and alkaline phosphatases during early pregnancy. Interacting effects of progesterone and oestradiol on the endometrial enzymes and the behaviour of the phosphatases in the caruncles during early pregnancy were also examined.
