Abstract
Since recent studies with somatostatin were carefully reviewed by Reichlin (1983) and by a variety of authors in the 2nd International Symposium on Somatostatin, which was held in Athens in 1981 but published with updates in 1984 (Raptis et al., 1984), no attempts are made to cover new developments with somatostatin-14 and somatostatin-28. Instead, this chapter focuses on the recent work in the field of somatostatin analogues and the investigations of their endocrine, gastrointestinal, and antitumor activities.
