Possible synergistic chemopreventive effect of the interaction between Res and BTP against DMBA and TPA-induced mouse skin tumorigenesis.

All the data are statistically significant, paExpected value of Res and BTP combination = [(observed value of Res)/(control value)]×[(observed value of BTP)/(control value)]×(control value).bRatio = (expected value/observed value). A ratio of>1 indicates a synergistic effect, and a ratio of O, observed; E, expected; R, ratio; Res, resveratrol; CNT, cumulative number of tumors; ANT, average number of tumors/mouse; ATV, average tumor volume/tumor bearing mouse.
