Effect of low-intensity laser radiation on peripheral blood eosinophils.

摘要

The study was performed on peripheral blood eosinophils isolated on a Ficoll-Verografin continuous-density gradient. Low-intensity laser radiation (lambda=0.89 mu, 25-30 mW power, 8 min exposure) induced degranulation of peripheral blood eosinophils. The effect of low-intensity laser radiation was realized via activation of calcium channels.
