A General Remark

　Professor Yoshimura and Yas Kuno！ It is very great honor for me to have so many of you come not only from this city, but from cities far away to participate in this symposium on active transport.

　As Professor Yoshimura has said, this is the subject in which I have been interested for many years. I would say at the outset, however, that many of you here are doing the important work in this field at the present time and that my own most active contribution has been sometime in the past.
