| Outline of Final Research Achievements |
The formulation which be available for oral administration was studied for treating megaloblastic anemia based on deficient vitamin B12 (VB12) by stomach resection of gastric cancer patients, and improvement of patient’s quality of life. Liposome, one of the drug carriers, was selected for taking into the body without gastric intrinsic factor. It was expected that liposome was taken up via the microfold cell (M cell) on Peyer's patch cells of intestinal epithelium cell because the structure of liposome looks like that of virus. VB12 loaded liposome was increased VB12 concentration in serum compared to VB12 solution when mice was orally administered. It was expected that the absorptive process was involved in M cell. Thus, the usefulness of liposome was suggested for treating megaloblastic anemia as orally administrated formulation.
