title: The influence of negative ionization of the air on motor activity in Syrian hamsters (Mesocricetus auratus Waterhouse) in light conditions.
abstract: The motor activity of Syrian hamsters (Mesocricetus auratus Waterhouse) under the influence of negative ionization of the atmosphere applied for 10, 20 or 30 min per day was investigated. An ionizer with output of 14,000 light negative ions per 1 cm3 of air was used. Studies carried out in the light phase of a 12:12 h light/dark regime revealed a relation between the reaction of the animal and the time of day at which ionization was applied. Ionization for 20 or 30 min in the light phase decreased motor activity, while 10 min of ionization increased it compared to control animals. Ionization in the dark phase gave a more distinct rise in activity than that applied in the light phase for all three durations of ionization.
