Biological effect of He-Ne laser: investigations on functional and micromorphological alterations of cell membranes, in vitro.

abstract：BACKGROUND AND OBJECTIVE:The extent of thermal injury during laser prostatectomy is dependent on the light distribution in laser-irradiated tissue. As tissue is irradiated, the optical properties change as a function of temperature due to an alteration of molecular and cellular structure. The purpose of the present stu...
