After oral administration of UFT and lingual topical application of 5-FU ointment to normal mice, the change of the concentration of 5-FU and Uracil in the tongue, liver and blood serum were studied. We compared with UFT only group, 5-FU ointment only group and the both combination chemotherapy group. 1. As for the tongue concentrations, 5-FU levels in both combination chemotherapy group and 5-FU ointment only group were higher compared to UFT only group. There was no difference between combination chemotherapy and 5-FU ointment only group. Uracil at 21-days in combination chemotherapy group were higher than others. 2. The liver concentrations of 5-FU at 21-days was significantly higher. 3. The blood serum concentrations of 5-FU in both combination chemotherapy and 5-FU ointment only groups revealed similar results. Thereafter, combination chemotherapy in oral region with topical application of 5-FU ointment and UFT may be effective.
