Effect of ultraviolet irradiation on calcium, sodium and potassium levels in albino rats

Data presented by the authors testifies to the fact that neither 2 weeks, nor one month after the 10-day course of ultraviolet irradiation (UVR) with an intensity from 1/4 up to 2 biodoses daily changes in calcium, sodium and potassium content in blood serum of laboratory animals (white rats) were detected. At the same time, 2 weeks following the cessation of UVR course a tendency towards calcium accumulation in the whole organism of laboratory animals was observed, which was most noticeable+ after daily 10-day exposure to UVR with an intensity from 1/2 up to 1 biodose. The tendency was still present one month following the termination of UVR course. The total sodium and potassium store in the whole organism of laboratory animals did not practically change either immediately, or 2 weeks, or 1 month after the termination of 10-day UVR course with the intensity from 1/4 to 2 biodoses daily.
