02/01/1990 - "The dose of 2.5 micrograms of TPA, which is usually used as tumor promoter in skin carcinogenesis, was equivalent to 50 micrograms of bilobol in irritant effect. "
02/01/1990 - "A comparative investigation of morphological changes induced by bilobol and TPA induced in the skin of CD-1 mice, and an assessment of the skin tumor promoting potential of bilobol were therefore performed. "
02/01/1990 - "Bilobol, isolated from ginkgo fruit pulp, has been noted to be a strong skin irritant like 12-O-tetradecanoylphorbol-13-acetate (TPA), a tumor-promoter in the skin. "
02/01/1990 - "Comparison of the effects of bilobol and 12-O-tetradecanoylphorbol-13-acetate on skin, and test of tumor promoting potential of bilobol in CD-1 mice."
02/01/1990 - "Treatment with either 10 or 50 micrograms bilobol twice a week for 30 weeks did not result in any tumor development, thus suggesting that bilobol is not a complete promoter of skin carcinogenesis, despite generation of inflammation."
