OBJECTIVE
To evaluate the possibility of oxygen radical damage in the skin after He-Ne laser irradiation according to dose intensity and time.
METHODS
The He-Ne laser (lambda = 632.8, 10 mW) was used on the skin of mice with 1, 3, and 5 joule (J/cm2) dose rates for 1, 5, and 7 days in each case, and

The aim of this study was to investigate the role of endogenous nitric oxide in protective effects of He-Ne laser on salt stressed-tall fescue leaves. Salt stress resulted in significant increases of membrane injury, reactive oxygen species (ROS) production, polyamine accumulation, and activities of

OBJECTIVE
To investigate whether a simulated He-O2 saturation dive to 65 msw would affect oxidative balance in humans.
METHODS
Seven divers participated in a simulated saturation dive to 0.75 MPa (65 msw). 24-h urine samples were collected twice before, twice during, and twice after the dive, then

The role of lipid peroxidation products formed in membranes of human blood leukocytes after irradiation with He-Ne laser was studied. It was found that low-intensity laser irradiation (0.3-1.6 J/cm2) leads to both cell activation and an increase in the content of lipid peroxidation products. The

OBJECTIVE
Our aim was to study photodecomposition, photomutagenicity and cytotoxicity of retinyl palmitate (RP), a principal storage form of vitamin A in humans and animals, under He-Ne laser photoirradiation. Moreover, the effect of different concentrations and timing protocol of antioxidants on
