[Professor Morii and my academic life].

Emeritus Professor Hirotoshi Morii was an important mentor in my academic life, who was a chief editor of CLINICAL CALCIUM with Professor Yoshio Yazaki for a long time. In the study of dopamine-β-hydroxylase, hyperthyroidism was able to prove hypotonic status for sympathetic nerve system by his valuable suggestion, though this condition was believed to be hypersympathetic till 1974 when my paper was published in Journal of Clinical Endocrinology and Metabolism. His suggestion struck me at that time. And this experience continues to give me an active power through my academic life.
