Aim of study (acc. to author)

To evaluate whether the increased frequency of complement-receptor positive splenocytes (splenic cells) by microwave irradiation is associated with elevated nucleic acid and protein synthesis.

Main outcome of study (acc. to author)

No significant differences between the incorporation of ³H-thymidine (DNA substrate), ³H-uridine (RNA substrate), and ³H-leucine (protein substrate) for microwave exposed and sham-exposed cultured cells were observed. A significant increase in the frequency of complement-receptor positive (CR+) splenocytes was observed. The increased number of CR+ splenocytes as a result of microwave exposure is not associated with significant changes in the rate of nucleic acid and protein synthesis in spleen cells, bone marrow, or peripheral blood lymphocytes.
