The tenth meeting of the International Foundation for Biochemical Endocrinology was held in Geilo, Norway near the end of September, 1982. The subject matter of the conference and the monograph was on "Regulation of Target Cell Respon- siveness." The local organizing committee was Asbj rn Aakvaag and Vidar Hansson. The scientific sessions covered a wide range of hormone action and cell response, including: peptide hormones and target cell response, regulation of insulin responsiveness, intracellular modulation of peptide hormone response, gonado- tropins and target cell responses, hypothalamic hormone- effects and regulation, steroid receptors and cellular control, hormones and growth regulation, and hormones and gene regulation. The chairpersons for the sessions were L. Birnbauer - A. Aakvaag, S. Taylor - R. S. Horn, F. Labrie - F. Rommerts, A. R. Means - K. W. McKerns, P. F. Hall - V. Hansson K. Griffiths - K. M. Gautvik, E. J. Peck, Jr. - E. Haug, F. S. French - W. T. Schrader, and E. M. Ritzen - B. Jegou. In addition to the scientific sessions in Geilo we were all delighted to sample some of the cultural and artistic attractions of Oslo, and to travel by train from Oslo via Geilo to Bergen. The scenery and hospitality were magnifi- cant.
