Results (1) CCD fluorescent microscope was superior to laser scanning confocal microscope in collecting the fluorescent image of DCF. CCD fluorescent microscope was chosen to be the system applied in this research with the consideration of operation, cost and et al. The mercury-arc lamp of fluorescent microscope was fit for the requirement of our study. The wavelength range of the light output was 460-490 nm and the power density was about 100mW/cm in the condition of our study. Organelle-cell fluorescence intensity ratio analysis was more suitable than other methods.
