3. Fig. 2
Fluorescence spectrum taken from normal area of aorta of atherosclerotic rabbit given hematoporphyrin derivative. Signals I1 at 615 nm and I2 at 632 nm are used to calculate plaque index (see text).

4. Fig. 3
Fluorescence spectrum of normal aortic wall and atherosclerotic plaque from rabbit not given hematoporphyrin derivative. Spectra are identical in their wavelength dependence; plaque shows only difference in intensity.

5. Fig. 4
Fluorescence spectrum taken from plaque of atherosclerotic rabbit given hematoporphyrin derivative. There is a spectral peak at 632 nm, which corresponds to fluorescence peak of hematoporphyrin derivative.
