Representative examples of the lungs and of the lung cross sections after UVA radiation and B16-F1 cell injection. (a) Metastatic nodules, which were clearly visible on the lung surface, were counted under dissecting microscope (magnification of the objective 6Ă—). (b) Lung cross sections (5 ÎĽm) were stained with H&E to determine the lung tissue morphology and the appearance of tumors (magnification of the objective 10Ă—).
