The effect of acute gamma irradiation (IR) on enzyme activity of rat brain Ecto-Nucleotide Diphosphohydrolase (E-NTPDase), in presence of adenosine triand diphophashates (ATP and ADP) and divalent cations (Ca2+ and Mg2+), has been investigated. The aim of research was to study the influence of low (50 cGy) and therapeutic (2Gy) doses of whole-body irradiation on rat brain E-NTPDase enzyme activity 24h after treatment in prepubertal and adult rats. Our results suggest that whole-body irradiation could induce modulation of neural activity in rat brain, especially in young rats.Physical chemistry 2008 : 9th international conference on fundamental and applied aspects of physical chemistry; Belgrade (Serbia); 24-28 September 200
