[Induction of various enzymes in the rabbit uterus with estradiol]

Effect of estradiol propionate on activity of seven enzymes from rabbit uterus was studied. Simultaneously with the known estrogen-induced enzymes, activity of some other enzymes from uterus cells (tyrosine transaminase, acetylcholinesterase, butyrylcholinesterase) was also studied. The hormone induced all the enzymes studied except of butyrylcholinesterase. After induction with the estrogen a new isoenzyme fraction was found in peroxidase: at the same time, content of isoenzymes of lactate dehydrogenase, tyrosine transaminase and acetylcholinesterase was increased.
