A Helium-Neon (He-Ne) laser with a wavelength of 632.8 nm is known to have photobiological effects and is widely used for reducing the pain of herpes zoster and accelerating wound healing, however the cellular mechanism and effect of the He-Ne laser are poorly understood. The present study was designed to examine the influence of He-Ne laser irradiation on irritant and allergic contact dermatit...
conclusions caffeic acid treatment reduced bacterial growth and resulted in a decreased number of colony formation. the simultaneous effect of caffeic acid and laser at three time courses showed a synergic effect in reducing colony formation compared to the control and caffeic acid, and laser alone. objectives the aim of this study was to investigate the effect of caffeic acid and low-power las...
We studied the protective effects of low power He-Ne laser irradiation on erythrocytes against the damage caused by experimental artificial heart-lung machines. The erythrocyte suspension in a closed circuit was perfused with a roller pump. One of two circuits was used for laser treatment and the other for control. The laser group demonstrated significantly higher erythrocyte deformability and ...
Purpose: Semen freezing is an important technique in human infertility treatment in many different patients but it damages sperms. Low-power lasers are physical agents that have biostimulatory effects. In this study, low-power helium-neon laser's (16J/cm2, one time irradiation) effect on motility and ultrastructure of fresh and frozen-thawed human sperm were studied. Materials and Methods: Thi...
