Microwaves and cellular immunity. II. Immunostimulating effects of microwaves and naturally occurring antioxidant nutrients. med./bio.

Aim of study (acc. to author)

To study the effect of weak 8.15-18 GHz microwaves on the tumor necrosis factor secretion and immune response. The aim of the study was to elucidate whether there is a synergism of the immunostimulating effects of low-intensity microwaves and antioxidants (beta-carotene, alpha-tocopherol, and ubiquinone Q9 were given daily with food prior to microwave exposure).

Main outcome of study (acc. to author)

A single 5 h exposure induced a significant increase in tumor necrosis factor production in peritoneal macrophages and splenic T cells. The mitogenic response in T lymphocytes increased after microwave exposure. The activation of cellular immunity was revealed within 3 days after irradiation. The diet containing antioxidant nutrients increased the activity of macrophages and T cells from exposed animals.
These data demonstrate that irradiation with low-power density microwaves stimulates the immune potential of macrophages and T cells. The antioxidant treatment enhances the effect of microwaves, in particular at later terms, when the effect of irradiation is reduced.
