“…Since the pioneering work of Markarian (1967) objective prism surveys were recognized as a powerful tool to search for galaxies of various types of activity. As the result of nearly a dozen large objective prism surveys completed during the two last decades the main statistical properties were derived for various types of AGNs and for galaxies with enhanced current star formation.…”

“…While the selection of objects from objective prism spectra by their enhanced UV continuum was the primary criterion applied by Markarian (1967) and has proven to be especially efficient in searching for new Seyfert galaxies and QSOs, as well as for various types of star forming (SF) galaxies, the selection on the base of strong emission lines was shown to be also very efficient both in search for AGNs and galaxies with strong current star formation.…”

“…They attracted much attention since their first description by Sargent & Searle (1970). Even earlier, these galaxies were recognized as objects which deserve attention in works by Haro (1956), Zwicky (1964) and Markarian (1967). As most of the BCGs have strong emission lines they can be classified as HII-galaxies as well (Veilleux & Osterbrock 1987).…”

Abstract. We present first results 1 of the Hamburg/SAO Survey for Emission-Line Galaxies (HSS therein, SAOSpecial Astrophysical Observatory, Russia) which is based on the digitized objective-prism photoplates database of the Hamburg Quasar Survey (HQS). The main goal of this survey is the search for emission-line galaxies (ELG) in order to create a new deep sample of blue compact galaxies (BCG) in a large sky area. Another important goal of this work is to search for new extremely low-metallicity galaxies. We present the first results of spectroscopy obtained with the 2.2 m telescope at the German-Spanish Observatory at Calar Alto, and with the 6 m telescope at the Russian Special Astrophysical Observatory. The primary ELG candidate selection criteria applied were a blue continuum (near λ 4000Å) and the presence of emission lines close to λ 5000Å recognized on digitized prism spectra of galaxies with magnitudes in the range B = 16. m 0 − 19. m 5. The spectroscopy resulted in the detection or/and quantitative spectral classification of 74 emission-line objects. Of them 55 are newly discovered, and 19 were already known as galaxies before. 11 of the latter have redshifts and are known ELGs. For most of the known galaxies emission line ratios were measured for the first time and an improved classification is presented. 47 objects are classified as BCGs, one as Sy2 galaxy, six as possible LINERs, and four as new QSOs.Send offprint requests to: and@sao.ru Deceased September 22, 1996. 1 Tables 1 to 5 are only available in electronic form at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsweb.u-strasbg.fr/Abstract.htmlThe remaining galaxies do not show significant Hβ and [Oiii] λλ 4959, 5007Å emission lines, and are likely either low-ionization starburst or dwarf amorphous nuclear starburst galaxies.

“…The origin of these has been attributed to the lack of physiological destruction by fibrinolytic tissural enzymes [12] or humoral enzymes [13]. We have found a reduction of the total plasma thrombolytic activity (balance of plasmin plus other circulating proteolytic enzymes, minus its anti-enzymes) normally very much increased in prematures without the disease [14].…”
