[UV-spectrophotometry in drug control. 47. Drug substances with chromophores and auxochromes in cyclic and tricyclic systems (benzodiazepine, dibenzoazepine and dibenzodiazepine)]. / UV-Spektrophotometrie in der Arzneimittelkontrolle. 47. Mitteilung: Arzneistoffe mit Chromophoren und Auxochromen in bicyclischen und tricyclischen Systemen (Benzodiazepin, Dibenzoazepin und Dibenzodiazepin.

The results of a systematic examination of the UV/VIS spectra of 10 drug substances with chromophores and auxochromes in bicyclic and tricyclic systems (benzodiazepine, dibenzoazepine and dibenzodiazepine) are described. Influences of substituents and solvents on shifts of the E, K, B and R bands are discussed.

[Application of scanning electron microscopy to studying the architectonics of the fibrous framework of the walls of large vessels]. / Primenenie rastrovoi élektronnoi mikroskopii dlia izucheniia arkhitektoniki voloknistogo karkasa stenok krupnykh sosudov

Scanning electron microscopy was used to study the architectonics of the connective tissue fiber framework in the walls of large arteries. Preliminary treatment of the vascular samples with proteolytic enzymes (protorysin, trypsin) offered a possibility of determining peculiarities attending distribution and interrelations of collagen and elastic fibers in different strata of the vascular wall.
