Light irradiating device for immunopotentiation

Abstract

Disclosed are a light irradiating device for enhancing cell-mediated immunity and a method using the same. The light irradiating device generates a radiation with a specific peak wavelength at 610±20 nm or 710±30 nm which activates the structure of proteins involved in the activation of T lymphocytes responsible for cell-mediated immunity thus effecting immunopotentiation.
