AB - The suppressive effects of ketamine on intracellular calcium has been reported in a variety of cells
although the mechanisms involved are not well understood. The aim of this work was to evaluate the ketamine
effect on the mitochondrial Ca2+ accumulation and the cellular Ca2+ mobilization using FLUO4-AM and flow
cytometry. The results showed that mitochondria from ketamine injected animals presented a lower ability to
retain calcium at concentrations higher than 20 μM, as compared with controls (saline injected animals). In addition, ketamine showed a significant decreased KCl-induced intracellular calcium concentration. KCl increased
calcium influx through cellular depolarization. According to the data presented herein, ketamine presents a
clear inhibitory effect on cytosolic Ca2+ transport mechanisms, independently from their action on the calcium
channel associated NMDA receptor.
