Results No any changes on fragrant pig skin in low and middle corticosteroid using group; but on skin of strong and super strong corticosteroid using group, macule and pigmentation appeared after 50 days of spreading.

结果：用低强度和中等强度药物的香猪在涂药期间及停药后皮肤未见明显变化，高强度组和超高强度组在用药50天左右皮肤上可见毛细血管扩张，并出现色素沉着斑；用药30天后表皮变化不明显，但黑素细胞出现上移现象，用药35天后上皮开始变薄，黑素细胞增多并上移。

This effect may be related to the declined proliferation of melanocytes and the inhibition of melanin synthesis in melanocytes.

5％烟酰胺对UVB诱导的色素沉着有明显的抑制，它主要是通过抑制黑素细胞的增殖和黑素细胞内黑素小体的合成而发挥作用。

Objective To observe the effects of melagenine extracted from human placenta on the proliferation and differentiation of a melanoblast cell line derived from mouse neural crest cells, NCCmelb4M5, and to elucidate the mechanism of repigmentation in vitiligo following melagenine therapy.

目的 观察从胎盘中提取的黑素生成素对小鼠成黑素细胞NCCmelb4M5增殖和分化的影响，从诱导成黑素细胞增殖和分化的角度，探讨其治疗白癜风的可能机制。

Melanocytes were cultured with H2O2, the proliferation and melanogenesis of melanocyte were analysed by MTT and NaOH assay.

培养的黑素细胞中加入H2O2，用MTT法检测黑素细胞增殖，NaOH法检测黑素合成。

Results After the application of 5% nicotinamide for 4 weeks, lightening effect was obviously observed with naked eyes and the L value decreased significantly.

5％烟酰胺对UVB诱导的色素沉着有明显的抑制，它主要是通过抑制黑素细胞的增殖和黑素细胞内黑素小体的合成而发挥作用。

Results There were negative expressions of α-MSH in both the hair follicle melanocytes of the Kunming white-mouse and the scarfskin of the FMN white-guinea pig; while there was positive expression in both the hair follicle melanocytes of the C57BL/6J black-mouse and the scarfskin of the HARTLY brown yellow-guinea pig.

结果］α-MSH在白色昆明小鼠毛囊及白色FMN豚鼠表皮中呈阴性表达，在C57BL/6J小黑鼠毛囊黑素细胞及棕黄色HARTLY豚鼠表皮黑素细胞中呈阳性表达。

Objective To establish human normal melanocytes cell line in vitro and observe the effects of Azelaic acid on the pigment production of the epidermal melanocytes and B16 cells.

目的 建立体外培养的正常人表皮黑素细胞系，检测壬二酸对人表皮黑素细胞和鼠黑素瘤B16细胞黑素合成的影响。

Vernonia anthelmintica can significantly enhance the activity of tyrosinase in vitro and proliferation of B-16 murine melanoma cell.

结果驱虫斑鸠菊体外可激活酪氨酸酶活性，增强B - 16鼠黑素瘤细胞增殖，提高酪氨酸酶和黑色素合成能力；对整体动物黑素细胞具有促进合成和分泌作用。结论在白癜风的治疗中，驱虫斑鸠菊可增强酪氨酸酶活性，进而促进黑素合成

Methods A routine culture system of melanocytes was established, cells were irradiated with different dosages of UVB(30 and 90mJ/cm2 respectively), and then incubated with different concentrations of TMP for 72h. MTT method, NaOH assay and DOPA oxidization reaction were employed to determine the cell proliferation, melanin synthesis, tyrosinase activity of melanocytes.

常规分离培养正常人黑素细胞，分别用30mJ/cm2、90mJ/cm2的UVB照射细胞，然后加入100μg/ml、300μg/ml、600μg/ml的TMP孵育至72h，采用噻唑蓝法测定细胞增殖情况；多巴氧化法测定酪氨酸酶活性；NaOH裂解法测定黑素含量。
