呼吸树

仿刺参体壁、肠和呼吸树全长cDNA文库的构建及部分ESTs初步分析

Construction of cDNA Libraries from Body Wall , Intestine and Respiratory Tree of Sea Cucumber ( Apostichopus japonicus ) and ESTs Analysis

采用组织学方法对刺参吐脏和再生过程进行观察，结果表明，刺参吐脏后便开始再生，吐脏后的第2天可观察到呼吸树主干及分支结构。

Japonicus by applying the method of histology . The result indicated that the A. japonicus started to regenerate immediately after the evisceration , and the respiratory tree trunk and the branched structure were observed on the 2nd day .

解剖观察发现，呼吸树水肿严重，有的甚至糜烂。

Edema and rot respiratory trees were observed under light microscope .

体腔上皮和内皮下连续成层的基膜围成呼吸树中封闭的血腔。

The obturated haemocoel was enclosed by the continuous and stratified basement membrane under the coelothelium and endothelial .

内皮层与内皮基膜构成呼吸树的呼吸膜，由泄殖腔进入呼吸树中央腔的海水和呼吸树血腔中的血液经此气-血屏障进行气体交换，完成呼吸作用。

The breathing film was made up of endothelial and endothelial basement membrane . The seawater in respiratory trees through cloaca into center antrum and blood in haemocoel accomplished respiration via this gas-blood barrier .
