Efficacy of combination of APS and curcumin on the morphological structure of tumor vessels. (A) Representative morphological structure of tumor vessels observed by photoacoustic tomography (PAT) at wavelengths of 680 nm; (B) vascular branches of each treated group; (C) vascular areas of each treated group; and (D) representative microstructure of the tumor vessels detected by scanning electron microscopy. Scale bar, 5 µm. Results are presented as the mean ± SD. **P < .01 versus vehicle control; ##P < .01 versus APS group; &&P < .01 versus curcumin group.
