紫外线照射后皮肤组织形态学变化动态观察

MORPHOLOGICAL CHANGES OF EPIDERMIS IN GUINEA PIG AFTER UVR

本文以全光谱紫外线３、６、９ＭＥＤ累积３次照射和１２ＭＥＤ１次照射豚鼠皮肤，动态观察照射后皮肤反应和皮肤组织形态学变化。结果表明，紫外线照射后引起皮肤不同程度的红斑反应，组织形态学观察呈急性炎症反应，照射剂量越大，炎症反应越明显，恢复时间越长。

The certain area of guinea pig’s epidermis were exposed three times underthe whole-spectrum ultraviolet radiation (UVR)with three doses of 3,6, 9 MED respective-ly;and one time with the dose of l2 MED in another group.Thereaction of epidermis and thetime course morphological changes were observed. The results show that UVR can cause epi-dermic erythema in different degree, which occurred to be acute inflammation morphologi-cally;and the higher the dose of UVR,the more serious inflammatory reaction appeared,sothat the longer recovering time is needed.
