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.
