Long-term effects of 222-nm ultraviolet radiation C sterilizing lamps on mice susceptible to ultraviolet radiation(far UVC light bulb, 300w largest power lamp)

Germicidal lamps that emit primarily 254 nm ultraviolet radiation are routinely utilized for surface sterilization but cannot be used for human skin because they cause genotoxicity. As an alternative, 222-nm UVC has been reported to exert sterilizing ability comparable to that of 254-nm UVC without producing cyclobutane pyrimidine dimers (CPDs), the major DNA lesions caused by UV.

However, there has been no clear evidence for safety in chronic exposure to skin, particularly with respect to carcinogenesis. We therefore investigated the long-term effects of 222-nm UVC on skin using a highly photocarcinogenic phenotype mice that lack xeroderma pigmentosum complementation group A (Xpa-) gene, which is involved in repairing of CPDs. CPDs formation was recognized only uppermost layer of epidermis even with high dose of 222-nm UVC exposure. No tumors were observed in Xpa-knockout mice and wild-type mice by repetitive irradiation with 222-nm UVC, using a protocol which had shown to produce tumor in Xpa-knockout mice irradiated with broad-band UVB. Furthermore, erythema and ear swelling were not observed in both genotype mice following 222-nm UVC exposure. Our data suggest that 222-nm UVC lamps can be safely used for sterilizing human skin as far as the perspective of skin cancer development.

We introduce leading-edge production technology of similar products at home and abroad to continuously improve our Multifunctional Eco Friendly Oral Care Deep Clean Electric Sonic Toothbrush for Adult. We are committed to improving our company's high-end user satisfaction, maintaining the stability of the company's high-end users, and improving the company's service level and economic income. Our company has strict management and strict discipline. The company implements a scientific management structure and a post responsibility system at all levels, which not only ensures the smooth flow of government orders, but also helps to give full play to personal potential, mobilize employees' enthusiasm and creativity, and ensure the organic combination of enterprise rationality and passion.
