【摘要】:目的:观察慢性紫外线(UV)损伤对小鼠角质形成细胞(KC)角蛋白(CK)1和CK10表达的影响。方法:将实验小鼠随机分为空白对照组(20只)和UV损伤组(20只),采用UV光疗仪模拟日光中的长波紫外线(UVA)和中波紫外线(UVB)照射实验小鼠。照射从最小红斑量起始,UVB为0.07 J/cm~2,UVA为0.7 J/cm~2;每日1次,每周5 d,每周增加0.5个红斑量,连续照射9周,UVB累计照射剂量达9.45 J/cm~2,UVA累计照射剂量达94.5 J/cm~2。通过苏木精-伊红(HE)染色和间苯二酚-碱性品红染色(Weigert染色法)确定皮肤损伤,通过免疫组化方法分别对照射前(W0)、后(W9)CK1和CK10的表达进行检测。应用配对t检验和独立样本t检验对相关数据进行统计分析。结果:空白对照组小鼠W0及W9时,CK1和CK10的表达差异均无统计学意义(P均0.05)。UV损伤组小鼠W0和W9时,CK1和CK10的表达差异均有统计学意义(P均0.05)。且UV损伤组小鼠CK1和CK10的表达呈明显的定位改变。结论:多次UV照射能导致小鼠模型中CK1和CK10的表达明显上调且定位异常。
[Abstract]:Aim: to observe the effect of chronic ultraviolet (UV) injury on the expression of (KC) keratin (CK) 1 and CK10 in mouse keratinocytes. Methods: the experimental mice were randomly divided into blank control group (n = 20) and UV injury group (n = 20). Long wave ultraviolet (UVA) and medium wave ultraviolet (UVB) irradiation were simulated by UV phototherapy instrument. From the beginning of the minimum erythema dose, UVB was 0.07 J 鈮,
