The editor is happy to present volume 30, a Jubilee volume, to the read- ers of "Progress in Drug Research". In the 27 years of its existence, this series of monographs has published more than three hundred suvey- articles covering almost all aspects of drug research, thus providing the opportunity of using the monographs for encyclopedic information. It is the editor's hope that the new volume, which contains 12 contribu- tions, will also be interesting and useful, both to those who are actively engaged in research and to those who wish to keep abreast of the latest developments and cannot afford the time to read all the numerous spe- cific puplications. The 12 contributions of volume 30 are particulary concerned with im- munopharmacology, progesterone receptors, brain neurotransmitters, hypertension, 5-hydroxytryptamine receptors, beta blockade, myo- cardial infarction, confirmation analysis malaria, tissue dwelling hel- minth parasites, oral anti diabetics; various problems of drug dis- covery are also dealt with. In addition, this volume contains a subject index, an alphabetical article index and also an author and subject in- dex for all the volumes so far puplished.
On the occasion of this Jubilee Volume, the editor would like to take the opportunity of thanking not only the authors who were prepared to undertake the task of writing the present extensive surveys, but also to express his gratitute to all the previous authors who were also pre- pared to share their vast knowledge and experience with the readers.
