| Outline of Final Research Achievements |
Oil based formulation for transdermal vaccine was developed. Oil easily penetrates in stratum corneum, however, it is hard to combine hydrophilic materials such as protein type antigen. We developed lecithin reverse wormlike micellar solution with light type liquid paraffin as oil, and water/glycerin mixture as polar material and succeeded to mix ovalbumin. Rheological characteristics of this formulation showed appropriate for penetration in narrow pore of the skin. The penetration of FITC-OVA into the skin was improved. Subcutaneous injection of this formulation increased OVA antibody value about 100-times higher than that of OVA solution. The formulation also increased antibody after skin application with closed condition, however, it was not large enough. It is necessary to combined use of other penetration enhance methods.
