20090042238 | Method of evaluating cell function, system for evaluating cell function, fluorescent microscope system, phototherapy method and phototherapy system - A proposition is to accurately evaluate a phototoxic property (cell function) concerning a living cell. To this end, an evaluating method of cell function includes the operations of dyeing a specific site of the living cell with a fluorescent dye, irradiating the living cell with light to measure changes in brightness of resulting fluorescence generated at an adjacent site of the specific site, and evaluating the phototoxic property based on the brightness changes. In the event of functional depression in the specific site, the fluorescent dye cannot be retained therein and is extravasated into the adjacent site through the membrane of the specific site. The present embodiment can measure the extent of this extravasation, making it possible to accurately evaluate the phototoxic property. | 02-12-2009 |
