In December 1997, more than 680 children developed convulsive seizures while watching a notorious audiovisually provocative TV program, "Pocket Monster." Emotional stimulation via hyperventilation may cause respiratory alkalosis, fall of blood ionized calcium (Ca), and sensitization of the nervous system to excessive emotional stress. A study was therefore undertaken to follow the changes of blood ionized Ca in eight healthy volunteers after watching the "Pocket Monster" and also a quiet program, "Classical Music," as a control for 20min from 4 P.M. Although neither marked hyperventilation nor convulsions developed in any of these adult volunteers, blood ionized Ca showed a significantly more pronounced fall during and after watching "Pocket Monster," and their plasma intact parathyroid hormone (iPTH) was significantly higher 120min after the beginning of "Pocket Monster" than the "Classical Music" program. Plasma total Ca, pH, and albumin were free of detectable changes. Ingestion of 600mg Ca as active absorbable algal Ca (AAA Ca) with high bioavailability completely prevented the fall of ionized Ca and suppressed iPTH. Plama osteocalcin was also significantly suppressed after ingestion of AAA Ca. It may be worthwhile to ingest AAA Ca before anticipated emotional stress such as watching a provocative TV program to prevent possible neuromuscular instability.
