The actions of NO and H2O2 on gross K+ and Ca2+ currents were investigated on cultured identified neurons of the mollusc Lymnaea stagnalis (L).

Pedal I Cluster (RPeI) neurons were isolated and cultured for 1 - 5 days and K+ and Ca2+ currents were measured in the whole cell patch clamp configuration.

Both H2O2 (3 µM to 300 µM) and NO (0.1 mM to 1 mM) substantially decreased L-type Ca2+ and K+ currents in a concentration-dependent manner. These effects were partially reversible.

Both free radicals also increased intracellular calcium concentration ([Ca2+]i) in these neurons, clarifying an earlier study.
