摘要: 利用石蜡切片法、扫描和透射电镜技术及组织化学方法,对栉孔扇贝的晶杆进行了研究.晶杆分头部和杆部,横切面呈同轴圆环状,无细胞结构,头部边缘呈溶化状态,内含大量的吞噬细胞和嗜曙红颗粒,杆部表面有球状分泌颗粒.晶杆的电子密度较低,偶尔有带状高电子密度区、电子致密颗粒和电子透明小泡.晶杆内含粘蛋白、酸性粘多糖和蛋白质,无酸性磷酸酶、碱性磷酸酶、脂酶及酯酶活性.栉孔扇贝的晶杆无贮存食物的功能,大小与贝体的性别无关,长时间暴露的在空气中,晶杆消失Abstract: The morphological,histological and histochemical aspects of the crystalline style of Chlamys farreri were studied using light microscopy,scanning and transmission electr on microscopy and histochemical methods.The crystalline style is divided into two parts:the head and the rod.It appears in transverse section to be shaped the annual ring,no cell and cytoplasmic organelles contain in it,the edge region of the head usually in dissolved condition,a lot of phagocytes and eosinopilic granules exist in this area.There are secretory vesicles on the surface of the rod.The electron-density of the cr ystalline style is low.Electron denser zone,high electron density granules and some electron-lucent vesicles present somewhere.The histochemical results show that the crystalline style contains mucin, acid polysacchride and protein,but no acid phosphatase,alkaline phosphatase,lipase and ester ase activity.The crystalline style hasn't the role of food storage.Difference in the style size is not found between the male and the female,and the style will become dissolved after the scallop being exposed in the air a long time.
