摘　　要：用组织学和组织化学方法对仿刺参Apostichopus japonicus体壁的结构和成分进行了研究。组织学研究结果表明：仿刺参体壁自外向内由上皮层、结缔组织层、肌肉层和体腔上皮层组成。上皮层主要包括一层薄的角质层和2—3层上皮细胞，结缔组织层内含丰富的胶原纤维，肌肉层主要是平滑肌，体腔上皮层由单层扁平上皮组成。组织化学研究结果表明：仿刺参体壁各层（除体腔上皮层外）均富含糖类和蛋白质，不含脂类；碱性磷酸酶和酸性磷酸酶在体壁中存在酶活性的部位相同，主要在结缔组织层的空洞状结构处以及结缔组织层与肌肉层交联处。The body wall of sea cucumber Apostichopus japonicus was studied by histological and histochemical methods. The body wall consists of epithelium layer, connective tissue layer, muscular layer and coelomic lining. The epithelial layer includes a piece of thin cuticle and 2 - 3 layers of epithelia. There are loose collagenous fibrils in the connective tissue layer. Muscular layer is made up of smooth muscle, and the coelomic lining comprises of a simple squamous epithelium. The body wall contains glucide and protein besides fat. Acid phosphatase and alkaline phosphatase activities are found in the connective tissue layer and muscular layer.
