Typeset by Macmillan India Ltd, Bangalore. Andrew V. ScbaUy Roger Guillemin DEDICATION The present advanced status of our knowledge of the mechanism of in teraction of the hypothalamus and adenohypophysis rests on the solid foundation laid down by many workers over the past four decades. Foremost amongst these contributions have been the isolation, structure determination and syntheses of hypothalamic releasing factors in the laboratories of Drs Andrew V. Schally and Roger Guillemin. These contributions were recog nized in 1977 by the award of the Nobel Prize in Chemistry to Dr Guillemin and Dr Schally. 'For their discoveries concerning the peptide hormone production of the brain'. It is with great pleasure that we dedicate this volume to Drs Andrew Schally and Roger Guillemin and their co-workers.
