[Age-related diagnostic features of congenital atrial septal defect in adults according to the data of radiodiagnostic studies].

Objective: To reveal diagnostic features in atrial septal defect (ASD) in different age groups; to define a role of X-ray study in the diagnosis of ASD.

Material And Methods: Forty-eight patients (16 men and 32 women) aged 15 to 71 years with ASD at different sites were examined. All the patients underwent chest X-ray, echocardiography, and cardiac phase-contrast magnetic resonance imaging (MRI).

[Rapid determination of microbial sensitivity to antibiotics by using laser spectroscopy].

A method of express-determination of the susceptibility of microbes to antibiotics is presented based upon the registration by the method of laser spectroscopy of changes of optic properties of cultures at early terms of their incubation in liquid nutrient media with addition of antibiotics. The method was elaborated in 13 standard strains of Staphylococcus aureus and Escherichia coli with antibiotics of different classes, tested on the microflora of pus of patients with sepsis, verified by the method of serial dilutions of the antibiotic. The method makes it possible to obtain the minimum inhibiting concentration of antimicrobial preparations 1 h after the moment of obtaining the native material.

[Effect of the proteinase isolated from a fungus on the kallikrein-kinin system].

Carboxyl proteinase (CP) with the isoelectric point of 6.3-6.4 was isolated from a fungus at the Laboratory of Enzymology of the All-Union Research Technological Institute of Antibiotics and Enzymes and its effect on the kallikrein-kinin system and trypsin caseinolytic activity was studied.
