AB  - The aim of our study was to test the effect of subacutely applied micronized zeolite [micronized clinoptilolite (MZC)] on brain status of iron (Fe), reactive oxygen and nitrogen species (ROS, RNS), and radioprotective role against brain oxidative/nitrosative stress (OS/NS) initiated by single ionizing radiation of 2 or 10Gray (Gy). Wistar rats on normal (n=18) and 5% MZC supplemented diet (n=18), during 4 weeks, were internally subdivided into 3 subgroups (6 rats in each subgroup), with one of subgroup remaining as a control, and the other two subjected to single ionizing radiation of 2Gy or 10Gy. Thus, we had groups on normal diet: C – controls, 2Gy and 10Gy; and on 5% MZC supplemented diet: MZC, MZC+2Gy and MZC+10Gy. Concentrations of nitrates (a final RNS metabolite) and superoxide anion radical (O2 •-) (an initial ROS) were measured in homogenates of selective vulnerable brain regions (cerebellum, hippocampus and forebrain cortex), while Fe was determined in whole brain of rats. Results documented a significant drop of Fe in MZC and MZC+2Gy/10Gy groups; decrease of O2 •- and nitrate in MZC group; almost equal drop of O2 •- , in 2Gy and MZC+2Gy groups; and nitrate increase in 10Gy and MZC+10Gy groups. We confirmed that subacute MZC pretreatment contributes to partially accomplished brain radioprotective effect in rats exposed to single radiation dose of 2Gy and 10Gy, probably due to reduced OS/NS and Fe.
