采用正常成年犬体内注射氚化l-亮氨酸研究棒外节更新。注射后不同时间取眼，准备视网膜进行光镜放射自显影。竿外节盘片迁移与其他物种相似，即盘片在外节基部产生，并随时间迁移。平均周转时间为6天。圆锥体外段未显示标记蛋白的条带，而是像其他物种报道的弥散标记。
Tritiated l-leucine was injected intravitreally into normal adult dogs to study rod outer segment renewal. Eyes were removed at various times after injection and the retinas prepared for light microscope autoradiography. Rod outer segment disc turnover was found to be similar to other species, i.e., discs were produced at the base of the outer segments and migrated sclerad with time. The time for turnover averaged 6 days. Cone outer segments never showed banding of the labeled protein but rather a diffuse label such as reported in other species.
