Some histochemical and particularly histoenzymological tests are performed on the subcommissural organ of chick embryos. A secretory activity appears about the 7th day. In 10 days old embryos and new hatched chicken the enzyme activities are of rather low intensity. Compared with the 10 days embryos, the newborn show some increase, but compared with the adult birds the activities remain weak. However the acid phosphatase activity is higher in the subcommissural organ than in the ependyma even in 10 days embryos.
对鸡胚的连合下器官进行了一些组织化学尤其是组织酶学检测。在大约第7天时出现分泌活动。在10日龄胚胎和新孵出的雏鸡中，酶活性强度相当低。与10日龄胚胎相比，新生雏鸡有一定增加，但与成年鸟类相比，活性仍然较弱。然而，即使在10日龄胚胎中，连合下器官中的酸性磷酸酶活性也高于室管膜中的活性。
