Abstract
The effect on their behavior of chronic exposure to infrared laser radiation applied to the skull of rats was evaluated. The experiment was carried out on 20 Wistar white male rats. A semiconductive infrared laser (wavelength -- 904 nm, frequency -- 100 Hz, pulse duration -- 10 ns, mean power 10 mW, energy density 1.5 J/cm2) was used. A skull fornix of rats was irradiated with use of multidiode probe, 10 minutes daily for 14 consecutive days. A locomotor activity was determined in the `open field' test. Simultaneously, an exploratory activity was examined in the `hole' test. Space memory was determined by means of a water maze test. Afterwards, an irritability was investigated by means of the score of Nakamura and Thoenen. The evaluation of behavior was made 24 hours after a single irradiation, at the 7th and 14th day of repeated everyday irradiation and then at the 7th and 14th day after the end of the cycle of irradiations. Obtained data show that low-energy laser radiation does not affect the rats central nervous system, resulting in persistent changes of behavior.
