Low vitamin D and insufficient sun exposure are additive independent risk factors for the development of multiple sclerosis (MS). The usual measure of vitamin D status, serum 25-hydroxy vitamin D [25(OH)D], is also a marker of recent exposure to the UVB rays of sunshine. The main evidence for a protective effect for MS development of higher 25(OH)D comes from observational studies, but this stu...
In addition to therapeutic options such as steroid ointment, immunosuppressive drug and ultraviolet phototherapy, recent reports have demonstrated the clinical efficacy of topical vitamin D3 for vitiligo vulgaris. However, there seems to be little clinical effect of vitamin D3 without UV exposure. In the present study, we evaluated the clinical difference of sun irradiation vs. narrowband UVB i...
To investigate whether low-level lighting is necessary and which narrow-band light spectra are effective in seeds germination, of 14 genotypes from begonia, echinacea, gerbera, petunia, vinca were germinated under ultraviolet-B (UVB), blue (B), green (G), red (R), far-red (FR) light, or darkness. Light-emitting diode (LED) fixtures provided all spectrum treatments except for UVB, was by a fluor...
Purpose: Skin is continuously exposed to many hazardous environmental factors such as ultraviolet radiation (UV). Many investigations have been shown to cause skin damages. The aim of present research was to study the effect of a single time of UVB radiation on the expression pattern of keratinocyte growth factor (KGF) gene in mice. Materials and Methods: UVB (30 mJ/cm2 and 50 mJ/cm2) were rad...
