To investigate the effects of a preliminary microwave irradiation of water solutions on their ion channel modifiying capability.
The water solutions were pre-exposed for 20-30 min and afterwards added to the cultured kidney cells.

The open-probability state of the potassium channels was influenced by the amount of calcium ions added to the solution (high calcium amount means a low open-probability state and vice versa). Depending on the open-probability state of potassium channels the application of a pre-irradiated solution increases or decreases the open-probability state of the channels. At low initial channel acitivity the solution increases the former and at high initial channel activity the solution inhibits the channel. The nature of these findings is unknown.
