Effect of air ionization on blood serotonin in vitro

The effect of negative and positive air ionisation on siliconized blood serotonin was studied in vitro. The experiments showed that within 10 min positive ionisation increased serotonin levels in total blood (+40%), plasma (+90%), erythrocytes (+50%) and thrombocytes (+200%). On the other hand, negative ionization (10 min) lowered the serotonin content of total blood (−30%), plasma (−42.5%), erythrocytes (−41.7%) and thrombocytes (−72.3%), thus confirming the ‘Krueger Effect’ in vitro.
