川金丝猴胃的观察

OBSERVATIONS ON THE STOMACH OF RHINOPITHECUS ROXELLANAE

本文对川金丝猴（Ｒｈｉｎｏｐｉｔｈｅｃｕｓｒｏｘｅｌｌａｎａｅ）的胃进行了观察。其胃呈Ｓ形，自胃的左端至第一曲长１５ｃｍ，第一曲至第二曲长９ｃｍ，第二曲以下部长７ｃｍ。胃底包括左、右二盲囊，右盲囊可分前、中、后三部。二纵肌带沿胃的大、小弯行，纵肌带间形成两列肠袋样膨大。膨大自胃底向第二曲逐渐变小，第二曲以下为幽门部，胃管由贲门沿小弯伸至第二曲处。贲门周围为无腺区，其余部均有腺体分布。胃小凹明显。此外，对胃的分部、功能、形态成因以及一些结构术语作了讨论。

This paper deals with the stomach of R. Roxellanae. The stomach of R. Roxellanaeforms an S- shaped curve.The first part from the fundus ventriculi to the first flexure isabout 15cm. in length,the second part from the first flexure to the second, about 9cm,the htird part from the second flexure to the pylorus, the pars pylorica, about 7cm. Thefundus is divided into two parts termed the saccus cecus sinister and the saccus cecusdexter. The latter is subdivided into the anterior,middle,and posterior parts. The stom-ach has two longitudinal bands along the greater and lesser cuvature respectively.Thebands cause two rows of sacculations(haustra), the caliber of which gradually decreasesfrom the fundus to 2nd flexure. The canalis ventriculi begins at the cardia and passes a-long the lesser cuvature to end at the second flexure. The mucous membrane around thecardia is glandless, the rest of the mucous membrane is glandular.The foveolae gastricaeare clear. Besides , the divisions, function,case of formation and terms about some struc-tures have been descussed.
