研究了光照对野生青鳉鳞片白细胞的影响。将白细胞直接暴露在150或300勒克斯的光源下。完全分散的leucophores在M/7.5 KCl溶液和完全聚集的leucophores在生理盐水溶液中没有显示出任何明显的反应，除了一个非常活跃的布朗运动的leucosomes在照明下。另一方面，在肾上腺素能受体的刺激剂和抑制剂的作用下，白细胞团聚集，在光照下分散，并且发现这种反应是可逆的。从上述发现，可以得出结论，光直接诱导白细胞体分散在白细胞中，而没有肾上腺素能受体的任何介导。
The effect of light on leucophores of an isolated scale from the wild-type medaka Oryzias latipes was investigated. Leucophores were directly exposed beneath a light source of 150 or 300 lux. Fully dispersed leucophores in a M/7.5 KC1 solution and fully aggregated leucophores in a physiological saline solution did not show any noticeable response under illumination except for a very active Brownian movement of leucosomes. On the other hand, leucophores aggregated under the effects of both a stimulant and an inhibitor of the adrenergicƒÀ-receptor, dispersed under illumination and this response was found to be reversible. From the above findings, it was concluded that light directly induces leucosome dispersion in leucophores without any mediation of the adrenergic ƒÀ-receptor.
