Description	Nízkovýkonný laser je využíván v četných terapeutických postupech. Tato studie přináší výsledky o účincích terapeutického laser na buněčné úrovni. U protozoí Euglena gracilis a Tetrahymena thermophila byly studovány změny v pohyblivosti po ozáření 830 nm a 650 nm laserem (99 J/cm2, 360mW) a laserovým ukazovátkem (0.75 J/cm2, 5mW). Změny v pohybu byly registrovány TV kamerou a počítačovou analýzou bylo zjištěno zrychlení pohybu. (cs) Low-power lasers are commonly used in human medicine for treatment of various pathological conditions but mechanisms of their healing effects are still poorly understood. The results of this study provide information related to these effects at the cellular level. Two different protozoan species, Euglena gracilis and Tetrahymena thermophila, were used to study changes in locomotion behavior in response to low-power lasers. The cells were irradiated at 830 nm and 650 nm generated by a semiconductor laser (99 J/cm2, 360mW) and a laser pointer (0.75 J/cm2, 5mW), respectively, and their locomotion was recorded by a TV camera and analyzed by computer software. Exposure to laser light, regardless of the wavelength, resulted in increased cell velocity in both species (P<0.001).
