Differences in the Effects of Broad-Band UVA and Narrow-Band UVB on Epidermal Keratinocytes.

ABSTRACT:

Background

The sun is a natural source of UV radiation. It can be divided into three bands, UVA (315-400 nm), UVB (280-315 nm) and UVC (100-280 nm), where the radiation up to 290 nm is very effectively eliminated by the stratospheric ozone. Although UV radiation can have a beneficial effect on our organism and can be used in the treatment of several skin diseases, it must primarily be considered harmful.

Methods

In the presented work, we focused on the study of the longer-wavelength UV components (UVA and UVB) on the human epidermal keratinocyte line HaCaT. As UVA and UVB radiation sources, we used commercially available UVA and UVB tubes from Philips (Philips, Amsterdam, The Netherlands), which are commonly employed in photochemotherapy. We compared their effects on cell vi
