Lepromin test

Kensuke Mitsuda wrote in 1919 his first paper on lepromin test, also called Mitsuda's skin test later. But he regarded himself a pathologist and not an immunologist, so, he wanted other researchers of leprosy who came under him to complete it. Among other researchers, Fumio Hayashi completed it. Hayashi read a paper on it at a leprosy conference at Bangkok. Masao Ota, a dermatologist who also studied leprosy, was very much impressed by the paper, and tried to publish International Journal of Leprosy. Hayashi's paper was in its first issue.
