Abstract

Calcium binding proteins CaBPs such as calbindin D28-k, parvalbumin, and calretinin are able to bind Ca

with high affinity. Changes in Ca

concentrations via CaBPs can disturb Ca

homeostasis. Brain damage can be induced by the prolonged electromagnetic field EMF exposure with loss of interacellular Ca

balance. The present study investigated the radioprotective effect of ginseng in regard to CaBPs immunoreactivity IR in the hippocampus through immunohistochemistry after one-month exposure at 1.6 SAR value by comparing sham control with exposed and ginseng-treated exposed groups separately. Loss of dendritic arborization was noted with the CaBPs in the Cornu Ammonis areas as well as a decrease of staining intensity of the granule cells in the dentate gyrus after exposure while no loss was observed in the ginseng-treated group. A significant difference in the relative mean density was noted between control and exposed groups but was nonsignificant in the ginseng-treated group. Decrease in CaBP IR with changes in the neuronal staining as observed in the exposed group would affect the hippocampal trisynaptic circuit by alteration of the Ca

concentration which could be prevented by ginseng. Hence, ginseng could contribute as a radioprotective agent against EMF exposure, contributing to the maintenance of Ca

homeostasis by preventing impairment of intracellular Ca

levels in the hippocampus.
