Histological special staining and dehydrogenase histochemical techniques were used to observe the structure and staining reactions at the junctions of side-arm branches of retinal arteries in man and several species of animals. Annular stains occurred at the junctions of side-arm branches in cat, rat, pig and dog, but not in man, rhesus monkey and beef with PAS, Masson's and elastic Van Gieson's (EVG) stains. However, in man and all the animals studied, they can be demonstrated with dehydrogenase histochemical techniques, i.e. succinate, malic and lactic dehydrogenases (SDH, MDH and LDH). The tissue components of retinal arteriolar annulus and its role in control of retinal circulation were discussed.
采用组织学特殊染色和脱氢酶组织化学技术，观察人和几种动物视网膜动脉侧支分支连接处的结构和染色反应。采用过碘酸希夫染色（PAS）、马森染色和弹性维多利亚蓝染色（EVG）时，猫、大鼠、猪和狗的视网膜动脉侧支分支连接处出现环状染色，但在人、恒河猴和牛中未出现。然而，在人和所有研究的动物中，用脱氢酶组织化学技术，即琥珀酸脱氢酶、苹果酸脱氢酶和乳酸脱氢酶（SDH、MDH和LDH）可显示这些连接处。文中讨论了视网膜小动脉环的组织成分及其在视网膜循环控制中的作用。
