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.
