Modulatory effects of ketamine on catecholamine efflux from in vivo cardiac sympathetic nerve endings in cats.

abstract：:Intracellular regulation of NMDA-receptor-mediated currents in cultured rat spinal dorsal horn neurons was investigated by means of simultaneously recording whole-cell currents and intracellular Ca2+ concentration ([Ca2+]i). During recordings in which EGTA (11 mM) was used to buffer intracellular Ca2+, NMDA currents s...
