It is considered that there are the logical and decided aspects and the probable ones in the thinking processes of the diagnosis made by physicians.<BR>In this paper, it was reported that we tried to resolve the problems of the diagnosis using the logical (Boolean) algebra on the point of view that the medical diagnosis would be deduced logically from the informations obtained from the cases. In order to do this study, fifty-four liver diseases was selected in the liver diseases. In the other hand, fourty-five symptoms symptoms and ninety-six laboratory examinations containing the liver function tests, X-ray examinations and laparoscopic and biopsy findings corresponded to these diseases were picked up. The logical equations were made from the matrix between the diseases the symptoms and the examinations. The logical equations were stored in the memory of the digital computer and the diagnosis was made by giving the informations obtained from the patient successively in the input of the computer. Explaining our method for the diagnosis of the complications, if the idea that a random complication of the diseases is decided as one other disease was adopted, the kinds of the complications will come up to the enormous numbers. Consequently, it is very difficult that this idea is made practical application. Therefore, on the basis of the hypothesis that some complication was the case which dominated a logical minterm in a logical equation, the possibility of the diagnosis of the complication were studied. An electronic computer presents an useful aid to establish the objectivity of diagnosis. But the method that entrustes the diagnosis to the computer in all points is not practical.<BR>It is desirable that the method should be made.a plan to aid reasoning of physician in diagnosis.
