[My hope for the future of the medical scientist--to the medical doctor of clinical laboratory medicine from internal medicine].

This is the essence of my last lecture to the medical students of Hiroshima University. My 38-year career as a medical school teacher can be sectioned three parts. My main four studies are shown at the third part. 1) We advocated respiratory physiologic-chemistry based on the relationships between pulmonary function and the constitutive chemical components of lungs. 2) We proved the mechanisms of hypertension at the molecular level by renin-angiotensin-adrenaline theory. 3) We showed the difference of mitochondria DNA in Diabetes Mellitus patients between Japanese and Chinese. 4) We suggested the necessity of standardization and holding common national reference values of main clinical laboratory tests by reporting our data. I am delighted that the very good studies of my colleagues achieved 500 IFs and express my gratitude for my colleagues' cooperation.
