| 摘 要： | 在文昌鱼卵及胚胎发育过程中,卵黄粒内存在一种结构,形态上有7—9个亚单位排列呈环的管,类似“微管”,其直径为500—700(?),具“负染色”性(醋酸铀和柠檬酸铅染色)。推测其成分可能为糖-蛋白和脂蛋白及中性脂肪的复合体;其功能可能与建成细胞成膜物质有关。

| Abstract: | Electron microscopic study on the yolk granules of amphioxus (Branchiostoma bel-cheri tsingtaoensis Tchang et Koo) egg and embryo revealed the presence of an unknown ultrastructure composed of set of 7-9 circularly arranged sub-units with the diameter about 500-700 A. It stained negative by uranyl acetate and lead citrate. It might be a complex of glyco-protein, lipoprotein and neutral fat with the possible function of formation of molecules for the membrane. |
