In the present study, we have evaluated cytotoxic effects, antitumor activities and metastasis inhibitory effects of Palsun brewing water in NIH 3T3 cells, human epitheloid carcinoma cells, and human skin melanoma cells. The light microscopic study showed morphological changes, AG-NOR (argyrophylic nucleolar organizer region) by silver chloride stain, and glycoprotein by PAS (periodic acid stain) reaction of the treated cells. Disruptions in cell organelles were determined by colorimetric methods; MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazoliumbromide) and SRB (sulforhodamine B protein) assays. These results suggest that Palsun Brewing Water retains no cytotoxic effects in NIH 3T3 cells and a growth-inhibitory activity in cancer cell lines.
