It's an important marine fishery resource with high economic values. Anatomical, histological and histochemical methods were used on the studies on the form, the organization and the location of relevant digestive enzyme in digestive tract of Sipunculus nudus, and discussed the relationship along morphology, structure and function.

本论文运用解剖学、组织学和组织化学的方法对裸体方格星虫消化道形态、组织结构和有关消化的定位及其分布进行了研究，探讨形态结构与功能的关系，以丰富星虫动物形态学、组织学和组织化学内容，为裸体方格星虫消化生理的研究及增养殖提供理论基础，并对星虫动物的分类具有重要作用。

The maxillofacial and brain injuries were examined. Craniptomy was done to animals of impact injury 6 hours after damage, however it was done to animals of explosive injury in different time point (1 hour, 24 hours, 72 hours, 7 days, 14 days after damage). The pathological characteristics of corelative tissues were examined in detail under light and electron microscopes. The content of LPO, SOD, NO in soft tissue, brain, blood, and cerebral water content were measured, compared with control. The distribution and tissue location of NOS were studied by histochemistical and immunohistochemistic methods. Their relationship was studied to assess the pathological and physiological characteristics of maxillofacial injuries and brain damage associated.

撞击伤各组动物于伤后6h、爆炸伤各组动物于伤后不同时期（1h、24h、72h、7d、14d）开颅检查颅脑损伤情况，切取伤区肌组织、左侧脑组织、脑干标本行光镜、电镜观察；测定伤后肌组织、脑组织与血中LPO、SOD、NO含量及脑水含量变化；并使用组织化学和免疫组织化学的方法，观察伤后脑组织中NOS的分布和组织定位，研究伤后机体的病理及病理生理学改变特点，以及颅脑损伤与机体自由基反应、NO含量改变之间的关系，证实其病理作用。
