| 摘 要： | 应用光镜和透射电镜对斑马鱼心脏的显微与超微结构进行了观察。结果显示,斑马鱼心脏由心室、心房、动脉球和静脉窦构成。心室呈棕红色,分层明显,分为心外膜区的致密层和心内膜区的海绵层。心房呈亮红色,仅由疏松的海绵层构成。心室的前方会发出一条动脉干(腹主动脉),动脉干的起始部膨大呈椭球状,称为动脉球。动脉球呈梨形,由内向外可分为内膜层、中间层和外膜层3层。静脉窦单独进行分离较难,因此未对静脉窦进行单独分离观察。本实验在心室、心房和动脉球中同时观察到telocyte间质细胞的存在,它们的形态瘦长,可分为细部和膨大部。在心室的心肌细胞内观察到多泡体的存在,它们常分布在心肌细胞的外缘,贴近肌纤维膜或者邻近心肌细胞外缘的线粒体。

| Abstract: | In this paper, the microstructure and ultrastructure of zebrafish heart were observed by light microscopy and transmission electron microscopy. The results showed that the heart of zebrafish was composed of four parts:ventricle, atrium, bulbous arterious and venous sinus. The ventricle is brown-red and the stratification was obvious, it was divided into a compact layer of the epicardial region and a sponge layer of the endocardial region. The atrium is bright red and consists only of a loose sponge layer. An arterial trunk (abdominal aorta) was issued in front of the ventricle and the starting part of the arterial trunk expands into ellipsoidal shape, called the bulbous arterious. The bulbous arterious was pear-shaped, which can be divided into three layers from the inside to the outside, and they were the inner layer, the middle layer and the outer layer respectively. The venous sinus was difficult to isolate separately, therefore, the sinus was not isolated and observed separately. In this paper, the presence of telocyte interstitial cells was observed in the ventricles, atrium and arterial spheres. Their morphology was slender and long and could be divided into podomeres and podoms. The presence of multivesicular bodies was observed in the cardiomyocytes of the ventricles, which were often distributed on the outer edge of the cardiomyocytes, close to the sarcolemma or adjacent to the mitochondria of the outer edge of the cardiomyocytes. |
