| Outline of Final Research Achievements |
For a purpose to determine a disease developing mechanism of gingival hyperplasia with the phenytoin, we examined the effect that metabolites (p-HPPH) of the phenytoin gave to human normal gingiva fibroblasts (HGF). As a result, p-HPPH was suggested to restrain the expression of collagen degrading enzyme (MMP-1) in HGF.
Then, we examined whether the inhibitor of the TRPA1 channel (HC030031) interfered restraint of the MMP-1 expression by p-HPPH to develop a therapeutic drug of gingival hyperplasia. As a result, the expression of mRNA of MMP-1 which decreased by administration of p-HPPH increased by the dosage of HC030031. As a result, we found that all materials have the effects similar to HC030031. Effect of Menthol was found to be the strongest in the three.
