(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.
(1) 成熟雌性大鼠的血清胆硷酯酶活性是成熟雄性大鼠的 3 到 5 倍。小鼠血清在活性上表现出类似的性别变化,但程度较小。
(2) 未成熟的雌性大鼠和可能衰老的雌性大鼠具有低的血清胆硷酯酶活性,与成熟雄性大鼠的活性范围相同。
