[Physical and chemical properties of the condensate of breathed-out air in healthy people]. / Fiziko-khimicheskie svoistva kondensata vydykhaemogo vozdukha u zdorovykh liudei.

The physical-and-chemical condition of condensate of breathed-out moisture (CBM) was studied by the computer-aided analysis of axis-symmetric drops' form in healthy subjects; such condition was found to depend on sex, age and smoking-addiction of the examined persons. The surface tension of the mentioned moisture correlated with its viscoelastic index and with relaxation. The metabolites of nitric oxide, lipids, urea, lactic acid (not uric acid) and of hydrogen peroxide were found to influence the physical-and-chemical parameters of respiratory moisture. Hydrogen peroxide had a reverse correlation with the CBM viscoelastic module. A status of the pulmonary surfactant can be evaluated by using the studied physical-and-chemical CBM parameters.

[The organizational and methodological aspects of teaching student interns clinical nephrology]. / Organizatsionno-metodicheskie aspekty obucheniia studentov--subordinatorov klinicheskoi nefrologii.

The analysis is given to experience in teaching clinical nephrology to subinterns at a therapeutic chair. The initial knowledge in nephrology assessed in undergraduates proved unsatisfactory. Guidelines are presented for lecturers as well as results of questioning surveys of the students. The students answers showed that individual clinical tasks appeared most difficult for them. The mean score fr home tasks was 3.1, good marks being given in 21% only. Poor knowledge was reported in resolving diagnostic questions, treatment of renal failure, treatment of the kidneys in systemic disorders of the connective tissue. The post-study test control stated considerable gain of relevant knowledge.

[Gouty heart defects]. / Podagricheskie poroki serdtsa.

The authors revealed heart failure in 7 of 216 patients with gout. Two of them showed isolated mitral valve insufficiency and two patients aortal insufficiency while combined aortal disease, combination of mitral and aortal insufficiency and combined mitral valve disease with aortal insufficiency occurred each in 1 patient. One could not find distinct dependence between the clinical variant of the course of gout and development of a definite heart failure. Clinical and electrocardiographic signs of the revealed kinds of cardiac abnormalities are described. The morphological changes of the valves are described on the basis of 2 autopsy cases. The possible mechanism of development of podagric heart failures is discussed.
