RESULTS
A. Target tissue exposure
The results from multiphoton imaging are represented in Figure 2. The
visual analysis of the fluorescence intensity indicated that liver
tissue in the group that received injections with a fluorescent dye,
acridine orange demonstrated an increase in fluorescent staining
compared to control group which received injections with deionized water
only (Figure 2). This confirms sufficient liver uptake of acridine
orange which has reached the target tissue following its administration
into the air sac.
