| 摘 要： | 采用组织学方法,较系统地观察研究了双齿围沙蚕(Perinereis aibuhitensis)主要器官的组织学特点。首次以组织学的形式表现出多毛类刚毛的细微结构——中空的短管状结构,以及腹腔内主要器官组织学特性、位置关系及其可能的生理功能。结果表明:双齿围沙蚕疣足拥有丰富的毛细血管网并着生刚毛;循环系统发达,由背腹大血管、环体节血管网和毛细血管网共同构成一个发达的循环系统,这与其体节断裂存活、再生的进化机制相适应;肌肉组织分为三种不同类型——环肌、纵肌和斜肌,在三者协调配合下,疣足、各体节及整个虫体的运动功能得以完善;消化道由前向后的组织学变化,主要体现为肌肉类型的变化以及肠道褶皱的逐渐丰富,显示了形态与功能的高度适应性。本研究结果为更加系统掌握双齿围沙蚕的生物学特征奠定了基础,并为其人工繁育、指示环境污染物情况提供了一定的科学依据。

| Abstract: | The main organs of Perinereis aibuhitensis was observed in histology using dissection under light microscope. For the first time, the fine structure of chaeta, the histological characteristics of main organs, and the spatial arrangement in the abdomen cavity were studied. By histological staining, abundant capillaries in each pair of parapodia with several setae were revealed. The circulatory system is well-developed, containing a dorsal vessel, ventral vessel, and circular vessel, which is consistent with its evolutionary mechanism. Three types of muscle tissue (ring muscle, longitudinal muscle and oblique muscle) were classified and they cooperated with each other to realize the movement among wart feet, various body segments, and the entire body. The histological characteristics of digestive tract from front to back show the changes of muscle tissue and intestinal folds, indicating its evolutionary adaption in structure and function. The results of this study laid a foundation for more detail and systematic understanding of the biological characteristics of P. aibuhitensis, and provided a certain scientific basis for its artificial breeding and for environmental pollution monitoring. |
