In order to study the oxidative stress-induced change in intracellular concentration of Ca<SUP>2+</SUP> ([Ca<SUP>2+</SUP>]i) and Ca<SUP>2+</SUP>-induced oxidative stress, effects of hydrogen peroxide and ionomycin, a calcium ionophore, on rat cerebellar neurons were examined using a flow cytometer and fluorescent dyes: fluo-3 for monitoring [Ca<SUP>2+</SUP>]i; 2'', 7''-dichlorofluorescin, for reactive oxygen species; and 5-chloromethylfiuorescein, for cellular nonprotein thiols. Oxidative stress induced by hydrogen peroxide dose-dependently increased [Ca<SUP>2+</SUP>]i and decreased the content of nonprotein thiols. Ionomycin increased oxidative metabolism and decreased the content of nonprotein thiols. Results suggest that oxidative stress induces an increase in [Ca<SUP>2+</SUP>]j While an increase in [Ca<SUP>2+</SUP>]i increases oxidative stress in neurons.
