Genotoxic agents can induce various DNA lesions. DNA-Protein Crosslinks(DPCs) were known as the important DNA lesions which could impair gene expression because DPCs had a high probability of resisting repair and persisting through cell cycle. This repair resistance of DPCs could have biological significance but had not been evaluated clearly yet. Most of the studies that have evaluated the repair of DPCs only compared the extent of DPCs repair with other DNA lesions. We injected K2CrO4, a genotoxic agent, into Sprague-Dawley rats intraperitoneally(5mg/kg) and isolated blood lymphocytes 12 hours later. These lymphocytes were cultured in the mitogen added growth media and mitogen free media separately. The degree of the repair of DPCs was monitored for 4 days by the K-SDS assay. 4 day later, the amount of DPCs decreased by 4.6% in the mitogen added media but in creased by 10.9% in the mitogen free media. These results showed that DPCs induced by K2CrO4 were not repaired easily and the DPCs were biologically significant DNA lesions. We thought the decrease of DPCs in the mitogen added media was not due to the repair of DPCs, but from the increase of normal cell proliferation. Therefore, it is very important to consider the proliferation of normal cells when estimating the repair of DPCs.

Lichen aureus is a variant of pigmented purpuric lichenoid dermatitis. The skin lesions usually appear asymptomatic rusty, copper, or orange colored roundish lichenoid erythematous-purpuric papules and patches on the lower extremities. Histologically, the epidermis shows minimal changes, with a dense lymphohistiocytic infiltrate observed in the superficial derrnis, typically distributed in a band-like fashion. The typical lesion is a single patch localized on the lower extremity. We report a rare case of segmental lichen aureus localized on the right lower extremity.
