Abstract

Two scientometric indices are reviewed: number of printed scientific works per 100 specialists per year and number of scientific journals per 1000 specialists. In 1973–1977 Brazilian chemists and pharmacologists published 15.8 scientific works per 100 specialists per year, in 1981–1985 Japanese physicians — 17.1 ones, in 1968–1986 Czechoslovakian physicians —17.1 ones, in 1978–1986 Hungarian physicians — 18.3 ones, in 1963–1979 Polish physicians — 18.5 ones, in 1983 Yugoslavian physicians — 20.1 titles per 100 specialists. In 1986 in USA 7.2 biomedical journals were issued per 1000 physicians, in Japan — 3.4 ones, in Spain —1.8 biomedical journals per 1000 physicians. In 1986 in USA 6.8 dental periodicals were published per 1000 dentists, Great Britain — 3.0 ones, in Canada — 2.6 ones, in Spain — 2.0 dental journals. The total number of world's biomedical articles and books' titles was 535,000 in 1967, 628,000 in 1972, 820,000 in 1978, 1.01 million ones in 1983 and 1.13 million titles in 1986.
