[Application of automated image analysis system Allegro-MC for morphometric research]. / Primenenie avtomatizirovannoi sistemy analiza izobrazhenii Allegro-MC dlia morfometricheskikh issledovanii.

Automated system of image analysis Allegro-MC is described, including its scheme and concise characteristic. System is used for automated macro- and micromorphometric studies. As the examples for the demonstration of system operation the following micropreparations were used: capillaries of rat uterus, demonstrated by Gomori alkaline phosphatase reaction, cerebral neurons, visualized using NADPH-diaphorase Hope and Vincent method, capillaries as demonstrated by electron microscopy. As a sample of macropreparation, carotid angiogram taken in direct projection, was used. The demonstration is supplemented by vital microscopic study of microvascular reaction in rat small intestinal mesenterium to irradiation with heliumneon laser.

[Mobility of the mitral valve cusps in mitral stenosis studied by 2-dimensional echocardiography]. / Izuchenie podvizhnosti stovorok mitral'nogo klapana u bol'nykh s mitral'nym stenozom s pomoshch'iu dvukhmernoi ékhokardiografii.

The object of the work was to disclose the possibilities of bimetric echocardiography in appraising the mobility of the mitral valve cusps in patients with mitral stenosis. The shape of the mitral cusp movement was studied in the longitudinal and transverse planes of the heart section. The results of the ultrasonic examinations were compared with the operative findings in 68 patients operated on for mitral stenosis. In satisfactory mobility of the valve, "sail-shaping" of the cusps is recorded in the longitudinal plane of the heart section and a concavity in the transverse plane in the period of diastole. In coarse fibrosis of the cusps, the diastolic movement of the surface of the anterior cusp is recorded as a displacement of a straight line which moves parallel to its initial position in the period of systole. Bimetric echocardiography makes it possible to determine exactly the character of the mitral valve lesion and determine the degree of mobility of the cusps in patients with mitral stenosis. This information may be decisive in choosing the method of surgical correction of the disease.
