Ultraviolet (UV) light is a physical carcinogen, and UV irradiation from sunlight has negative effects on human skin. UVB-induced inflammation is linked to excessive induction of various inflammatory cytokines/chemokines in many types of cells, including keratinocytes. The purpose of this study was to investigate the anti-inflammatory effect of water extract of Zingiber officinale, gingerol, and shogaol on UVB-induced skin damage in the human keratinocyte cell line HaCaT and C57BL/6 mice. To test for an effective compound to protect against inflammation in UV-damaged skin, we prepared a water extract of ginger rhizomes and examined the effects of Z. officinale, gingerol, and shogaol on cell viability and cytokine/chemokine production in UV-irradiated HaCaT cells. We also investigated the in vivo relevance of these findings in C57BL/6 mice using hematoxylin and eosin staining and cytokine measurements. A water extract of Z. officinale, gingerol, and shogaol inhibited production of cytokines in UVB-irradiated HaCaT cells effectively. Treatment with Z. officinale attenuated UVB-induced hyperplasia, infiltration of leukocytes, and dilation of blood vessels in the dermis of mice. Z. officinale, gingerol, and shogaol show potential as anti-inflammatory agents to protect skin against UVB irradiation damage.

D012867 Skin The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.
D014466 Ultraviolet Rays That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.
