本文定量研究了高尔基体在8+ ~ 13+期鸡心肌发育中的位置。此外，我们还研究了秋水仙碱对高尔基体位置和结构的影响。在心管和心环形成过程中，心肌细胞中高尔基体的位置与心前中胚层细胞中高尔基体的位置有关，但与大部分心管和心环肌细胞中高尔基体的位置完全不同。高尔基体在心肌前细胞和心肌细胞中的位置显示出明显的极性模式。讨论了高尔基体极性的可能意义。秋水仙碱处理后，微管消失，高尔基体失去极化，可见充满无定形物质和/或胶原原纤维的空泡。微管系统在维持高尔基体的结构和极性以及心脏果冻物质的胞浆内运输中可能发挥的作用被提出。
This paper presents a quantitative study of the position of the Golgi apparatus in the developing chick myocardium between stages 8+ and 13+. In addition we have studied the effects of colchicine on the position and structure of the Golgi apparatus. During the formation of the heart tube and loop the position of the Golgi apparatus in the myocytes situated in the vicinity of the dorsal mesocardium is related to that found in the cells of the precardiac mesoderm, but it is completely different from that found in the bulk of myocytes of the heart tube and loop. The position of the Golgi apparatus in both pre- and myocardial cells shows clear significative patterns of polarity. The possible significance of the Golgi apparatus polarity is discussed. After colchicine treatment microtubules disappear, the Golgi apparatus loses its polarization and vacuoles filled with amorphous material and/or collagen fibrils are observed. A possible role of the microtubular system in the maintenance of the structure and polarity of the Golgi apparatus and in the intracytoplasmic transport of the cardiac jelly materials is proposed.
