摘要:

背景:中药及其提取物在改善皮肤组织结构、提高抗氧化酶活性、抑制基质金属蛋白酶高表达、增强皮肤免疫防御功能等多方面对皮肤光老化起着防治作用。
目的:验证丹酚酸B对皮肤光老化的保护作用。
方法:同时建立小鼠皮肤体外细胞培养紫外线损伤模型及小鼠紫外照射致皮肤衰老模型,给予不同剂量的丹酚酸B,通过MTT法, 单细胞凝胶电泳等观察各组皮肤细胞损伤程度以及丹酚酸B对细胞损伤的保护作用,小鼠灌胃口服不同剂量丹酚酸B,通过对皮肤组织羟脯氨酸、超氧化物歧化酶等含量的检测,评价丹酚酸B是否具有抑制皮肤光老化的作用。
结果与结论:紫外照射可使皮肤丙二醛含量明显上升,羟脯氨酸含量,超氧化物歧化酶和谷胱甘肽氧化酶活性下降。丹酚酸B能有效地对紫外线引起细胞致死性损伤起到保护作用,能显著降低皮肤组织丙二醛含量,提高羟脯氨酸含量,超氧化物歧化酶和谷胱甘肽氧化酶活性而起到抑制皮肤光老化作用。结果证实丹酚酸B具有保护皮肤光老化作用。

Abstract:

BACKGROUND: Chinese medicine and its extract can improve skin structure, improve the activity of antioxidant enzymes, inhibit high expression of matrix metalloproteinase, and enhance the immune defense function of the skin, which plays a preventive effect against skin photoaging.
OBJECTIVE: To observe the protective effect of salvianolic acid B on skin photoaging in mice.
METHODS: Mouse skin cells were cultured and irradiated in vitro to prepare UV damage models, which were treated with different doses of salvianolic acid B. MTT and single cell electrophoresis were performed to observe the severity of skin injury and protective role of salvianolic acid B on cell injury. Skin photoaging models were prepared through UV irradiation in mice, and then model mice were intragastrically administrated with different doses of salvianolic acid B. Hydroxyproline and superoxide dismutase contents were determined to evaluate whether salvianolic acid B can inhibit skin photoaging.
RESULTS AND CONCLUSION: UV irradiation could increase malondialdehyde content in the skin, decrease hydroxyproline content as well as superoxide dismutase and glutathione oxidase activity. Salvianolic acid B could effectively protect the cells from UV damage, remarkably reduce malondialdehyde content in the skin, increase hydroxyproline, superoxide dismutase and glutathione oxidase contents, playing an inhibitory effect on skin photoaging. These findings indicate that salvianolic acid B has a protective effect on skin photoaging in mice.
