A NOTE ON SERUM CHOLINESTERASE VARIABILITY IN MALE AND FEMALE RATS.
(1) The serum cholinesterase activity of mature female rats is three to five times as great as that found in mature male rats. Mice sera exhibit similar sexual variations in activity, but to a lesser degree. (2) Immature female rats and probably senile female rats possess a low serum cholinesterase activity, in the same range as that of the mature male rats.
