The effects of ultraviolet irradiation on the accumulation of resveratrol and δ-viniferin as well as related enzymes in the pericarp of V. vinifera were studied in this paper.

摘 要：本文研究了紫外线辐射对酿酒葡萄品种蛇龙珠果皮中白藜芦醇及其二聚体合成的影响。

Aim To investigate the production and removal of cyclobutane pyrimidine diners after UVB irradiation and the effect of baikal skullcap root, szechwan lovge rhizome and epigallocatechingallate on the irradiation damage in HaCaT cells, and finally, to clarify the probable regulatory mechanisms. Methods HaCaT cells were cultured in RMPI-1640 medium with 10% fetal bovine serum. The time and dosage of UVB irradiation were conducted according to the experimental design. Tested medicines were added into the medium before or after UVB irradiation.

Fluorescence occurs when ultraviolet radiation from just outside the visible spectrum is absorbed and re-emitted as visible light,thus increasing the total amount of light refected from a surface.Fluorescent brightening agents are commonly added to paper and boards to make them brighten and whiter and to increase the possible density range that can be achieved when printing on them.

荧光发生时，紫外线辐射从外面可见光谱吸收和再音量为可见光，从而增加总额轻refected从surface.fluorescent增白剂补充常用纸张和议会，使他们 brightenandwhiter，并把可能的密度范围时，才能得到印刷出来。
