The biological activity of eight 1-oxa-4-aza-2-silacyclanes with the OSiCH(2)N fragment including 6-membered 2-sila-5-morpholinones (1-3) and 4-acyl-2-silamorpholines (4-6)and previously unknown 7-membered derivatives of salicylic acid (7, 8) was studied. Compounds 1 and 3-6 show the certain antihypoxic action. Compounds 2 (40 mg/kg), 4 (20 mg/kg), 6 (40(More)
The status of the taxa Elymus dahuricus Turcz. ex Griseb., E. excelsus Turcz. ex Griseb., E. woroschilowii Probat. and E. tangutorum (Nevski) Hand.-Mazz., all of which are sometimes treated as members of E. dahuricus s.l. or as constituting the E. dahuricus complex, has been investigated using morphological, biochemical (SDS-PAGE of endosperm proteins) and(More)
Organosilicon compounds possess a broad spectrum of biological activity [2]. However only a few are used in pharmacology [6]. The search for regulators of extreme states among organosilicon compounds is limited and has been carried out only among compounds of hypervalent silicon [4, 5]. In view of the possible role of silicon in effecting adaptation(More)

In murine experiments, whether resistance to acute cooling (air and immersion cooling) can be predicted has been studied. Prognostic tests have demonstrated to be effective and feasible. The criteria examined for each type of cooling (which may be accounted for by the specific features of the air and immersion types of cold effects) have been found to be of(More)
