Abstract
When a small amount of human blood serum is placed between two slides and heated to 110-120°C, the serum boils and foams appear, and when the serum dries a certain kind of figure remains.
It was noticed that this foam appearance of blood serum, a phenomenon discovered by Miyamoto and Inagaki (1), differs between the human and the animal blood sera, and between the healthy and the sick persons. The writer and his colleagues experimented on this foam appearance of blood serum mostly on the tuberculous patients with the healthy as controls. The figure may not be definitely characteristic of tuberculosis, but, that there can be figures characteristic for each disease, can be expected when we observe the figure from the serum of a small number of jaundice and cancer patients.
