The school was raised to Nagasaki Medical College in 1923. Prof. T. Yoritaka arrived at his post in Nagasaki Medical College under being in its ruins and earnestly made efforts for rebuilding the department with many of the department's alumni. The department was graduately equipped and developed until he retired in march 1964, and he produced many scientific achievements mainly in relation to biochemistry of amino acids. After coming home, he studied the primary structure of hemoglobins from many other species, especially primates with his many co-studied workers. Further, from about 1980, he started to study complete amino acid sequences of muscle myosin submits and completed them with Dr. T. Maita and the other faculty members, and retired in March 1992.
