Phenol oxidase activity of the iris and the ciliary body in normal young rats of three differently pigmented strains, Lewis (albino), E3 (light brown, hooded), and BDE (black, hooded), was studied using DL-Dopa. Applicability of the histochemical method was controlled with skin samples taken from the necks of the animals. In the pigmented strains, the appearance of newly formed pigment at the pigmented epithelium and stroma of the iris and ciliary body was observed. In the E3 animals, the reaction was slightly positive, while in the BDE rats it was more pronounced. No phenol oxidase activity was detected in the ocular structures of the albinotic rats.
使用DL - 多巴研究了三种不同色素沉着品系的正常幼鼠（Lewis（白化）、E3（浅棕色，有头罩）和BDE（黑色，有头罩））虹膜和睫状体的酚氧化酶活性。用取自动物颈部的皮肤样本控制组织化学方法的适用性。在有色素沉着的品系中，观察到虹膜和睫状体色素上皮和基质处新形成色素的出现。在E3动物中，反应呈弱阳性，而在BDE大鼠中则更明显。在白化大鼠的眼部结构中未检测到酚氧化酶活性。
