摘要
利用石蜡切片技术对澳大利亚亚比虾排泄器官———触角腺和膀胱进行了组织学观察研究。结果表明,亚比虾触角腺可分为端囊、迷路和肾管3个部分。端囊部分细胞呈柱状,细胞核位于基底部,细胞游离端向端囊腔呈球状突出。迷路部分细胞呈柱状或锥体状,细胞核位于中部或基部,胞质丰富且多数细胞的游离面形成泡状突起。肾管部分可分为3个区段,管壁细胞分别呈扁平、立方或矮柱状,细胞核靠近细胞顶部。在触角腺中分布有丰富的血腔。膀胱腔面为单层立方上皮细胞,膀胱腹侧壁较薄,背侧壁厚且有皱褶。
Histological method has been used to observe the excretory organs—the antennal gland and the baldder of Australia Crayfish Yabby (Cherax destructor).There are three regions in the antennal gland:coelomosac,Labyrinty and nephridial canal.Cells in coelomosac region are columnar,nuclei of the cells are located basally on the apical margins of the cells,cytoplasmic extrustions were found projecting into the lumen.In Labyrinty region cells are columar or cone with centricully or basally loscted nuclei,there are vesicle-liked projections on the apical margins of the cells.In terms of the shapes of the nephridial cells,nephrididal can be divided into three parts,the cells of those parts are respectively flat, cubic or low columnar with apically located nuclei.A lot of blood spaces are observed in antennal gland.The epthelial cells of the bladder are cubic,there are some short caeca on the dorsal wall of the bladder.
