(A), KYSE-510 cells were treated with different amounts of ethanol, red wines #1 (mature wine), #2 (young wine) or #3 (mature wine) for 6 days. The concentrations of the three red wines are equal to ethanol (mM/L) as indicated. The pictures were taken under microscope (Nikon, Eclipse, TE300). Original magnification × 100. (B): the viability and total cell numbers were counted after plated cells 6 days. The cells were treated as described in Fig. B. The results indicate that red wines markedly repress KYSE-510 cell growth. The bars represent Mean ± SE of at least three independent determinations.
