Scientific publications from three sectors of the Institute have analyzed for the period since 1979 till 1988 inclusive. The analysis is based on data of annual reference books Science Citation Index (SCI) and lists of publications of each researcher of the Institute. It is shown that with almost equal numerical strength of researchers and similar number of publications the sector of molecular physiology contributed 43.6% to cited works 48.2% of these works are included into database of SCI. Such indices for the sectors of neurophysiology and physiology of visceral systems accounted for 33%, 33.4% and 23.4, 18.4% respectively. It is of interest that 47.5% of references to the cited works of the molecular physiology sector were made by foreign scientists and self-citation constituted 17.4%, while for the other sectors such indices had a reverse relationship. The problem on objectification of estimation of research is under discussion.
