Argon Laser Micro-irradiation of Nucleoli
نویسندگان
چکیده
Laser micro-irradiation of cell inclusions has become a useful method in cell biology (1). A pulsed ruby laser microbeam system has been successfully used to study morphological and functional relationships within mitochondria of tissue culture cells vitally stained with Janus green B (2-6) . Recently, an argon ion gas laser microbeam has been used to place lesions on mitotic chromosomes of salamander lung cells in tissue culture; these cells were photosensitized by short pretreatment (5 min) incubation with a dilute (2 X 10's%o w/v) solution of acridine orange (7, 8) . The same argon system is also being used to selectively place lesions in the large sarcosomes (mitochondria) of beating rat myocardial cells in tissue culture without prior pretreatment with a photosensitizing agent (unpublished data) . Generally, the rapid pulse repetition rate and/or continuous wave capabilities, multiple or single wavelength capacity, wide power and energy range, wavelengths in the biologically active region of the spectrum, and the existence

متن کاملEffects of Laser Irradiation on Caries Prevention
Introduction: Although dental caries is a preventable disease, it is still common and remains a public health problem. One of the potentially effective preventive measures is the use of lasers. The purpose of this study was to review the studies about use of laser irradiation on the inhibition of carious lesions and the effectiveness of different commercial laser type (Nd:YAG, CO2, and Argon). ...
