[The development of pharmacology in Poznan in the years 1918-1939].

In the years 1918-1939, research in the field of pharmacology in Poznan was conducted mainly by graduates of Russian universities, Professors: J.H. Lubieniecki and A. Trzecieski. Just like the last Head of the Chair of Pharmacology of the Poznan University in that period, Professor R. Leszczynski, they had a comprehensive background as physicians, which they owed both to their medical studies, and to periods of study and research abroad. One of the main achievements of the Poznan pharmacologists was to introduce the lastest clinical methods, such as using medicines to affect isolated organs. Today, many of their attainments are only of historical relevance, for they were mainly concerned with medicines derived from plants, which have largely been supplanted by synthetic drugs in the period after World War Two.
