COMPARISON OF THE POTENCIES BETWEEN THE JAPANESE MITSUDA'S ANTIGEN AND THE FOREIGN MITSUDA'S ANTIGEN

Abstract

Comparison of the potencies between Mitsuda's s antigen presented by Wade or that presented by Mabalay and Mitsuda' s antigen (Lot 13) prepared in National Institute for Leprosy Research, (Japan) were made by means of the bacillary counting and in animal test and human test. As the results obtained, no differences were found in these tests, in spite of these antigens which were made from different leproma, in different laboratory and at different calendar year. Therefore, these three Mitsuda' s antigens were not suitable as materials used for the comparison of potency tests.
