Volume 29 of 'Progress in Drug Research' contains 10 articles, a sub- ject index for this volume, an alphabetic index of articles for volumes 1-29, and an author und subject index for all the volumes which have so far been published. The contributions of volume 29 are particularly concerned with drugs in general, hypertension and cardiovascular drugs, atherosclerosis, teratogenic hazards and carcinogenecity, hist- amine, dopamine agonists, tetrahydroquinolines and /J-carbolines, and meddicinal research. The authors have tried, and I think they have succeded, not only to summarize the current status of particular fields of drug research, but also to provide leads for future research activity. The articles of this vo- lume will be of special value to those actively engaged in drug re- search, and to those who wish to keep abrest of the latest developments influencing modern therapy. In addition, it is believed that the 29 vo- lumes of 'Progress in Drug Research' now available represent a useful reference book of encyclopedic character. The editor would like to take the occasion of the publication of this volume to express his grati- tude both to the authors and to the readers. The authors have willingly . undertaken the great labor of writing significant topical contributions, and many readers have helped the editor with criticism and advise. With these thanks, the editor would like to express his gratitude to the publishers, Birkhauser Verlag Basel, particularly to Messrs. H. 1. Ben- der, C. Einsele and A.
