Oxygen Transport to Tissue: Instrumentation, Methods, and Physiology (Advances in Experimental Medicine and Biology): 37 A

It can honestly be said that the scope and magnitude of this meeting surpassed initial expectations with respect to the number and quality of the papers presented. Our group has grown since we last met in Dortmund in 1971. This is a good indication that a spiraling of our interests has taken place with the effects of the initial good work felt, not just in one corner of the globe, but in all four. With such a start, it was only appropriate that an international society was formed at the meeting to further coordinate our mutual undertaking. Henceforth it shall be known as the International Society of Oxygen Transport to Tissue. A final note of acknowledgement should be made to those who were in the supporting cast, not only in making the meeting in Charleston and Clemson a success, but also in the compiling of this book. Gratitude is due to Dr. Daniel H. Hunt for his efforts, the end product of which you have in your hands. Considerable service was rendered by Mr. Robert J. Adams, Mr. Buddy Bell and Mr. Nathan Kaufman during the symposium itself. Much typing, organizing and record keeping was done by our lovely secretaries, Laura B. Grove, Muff Graham and Kaye Y. Zook.
