The regulatory effect of polychromatic (visible and infrared) light on human humoral immunity
Abstract
The immunological effects of visible and infrared light from laser and non-laser sources have remained insufficiently studied, which has restricted the use of light in the treatment of diseases associated with immune system disorders. The present randomized, placebo-controlled double-blind trial was designed to study changes in the humoral immunity of a large group of volunteers after exposure of a small body area to polychromatic visible and infrared polarized (VIP) and non-polarized (VInP) light (400–3400 nm, 95% polarization, 40 mW cm−2, 12 J cm−2 and 400–3400 nm, no polarization, 38 mW cm−2, 11.2 J cm−2, respectively). Serum immunoglobulins (Ig) M, A, and G were determined turbidimetrically, and the immune complexes (ICs) by
