Outline of Final Research Achievements

The present study aimed to evaluate the change in the number of neural cells and presence of apoptotic cells in rats for one month after expo¬sure to excessive microwave radiation. The rats were exposed to 3.0 kW of microwaves for 0.1 sec and were sacrificed after exposure. The neural cells were counted in the motor cortex and hippocampus [cornu ammonis 1 (CA1) and CA2] and the percentage of positive cells stained with terminal deoxynucleo¬tidyl transferase mediated deoxyuridine triphosphate nick end labeling (TUNEL) were also measured. There were no significant differences from the controls in the percentage of TUNEL positive cells in the motor cortex and hippocampus. The effects of microwave exposure on the brain remain unclear; however, microwave induced neurotrauma shows the same pathological changes as blast traumatic brain injury.
