[Diagnostic potential of ultrasound methods of studying the lymph nodes and indirect lymphoscintigraphy in lymphoproliferative diseases]. / Diagnosticheskie vozmozhnosti metodov ul'trazvukogo issledovaniia limfaticheskikh uzlov i nepriamoi limfostsintigrafii pri limfoproliferativnykh zabolevaniiakh.

Ultrasonic and radionuclide investigations of the lymph nodes have been performed in 342 patients with malignant lymphoproliferative diseases. A comparative analysis of the data obtained by sonography and indirect lymphoscintigraphy has specified diagnostic spectrum of these procedures. The accuracy and specificity of sonography and broad-scale visualization secured by it dictate primary usage of the procedure as a screening test in initial examinations and as a control sensitive estimator of the on-going treatment efficacy. Indirect lymphoscintigraphy is recommended as an adjuvant to echography for detailing topics and nature of the lymph node lesion and to assess the process above the diaphragm. Frequency and regimen of the examinations should be based on clinical demands.

[Gas exchange and blood circulation status in dogs following replacement of acute blood loss by perfluoro compound emulsions]. / Gazobmen i sostoianie krovoobrashcheniia u sobak posle zameshcheniia ostroi krovopoteri émul'siei perftorsoedinenii.

Blood circulation and gas exchange were examined after replacement of blood loss (50 ml/kg bw) in dogs by a preparation containing perfluorocompound (PFC) emulsion (20 v. %) and protein-salt solution (PSS) consisting of isotonic solution of electrolytes and donor's albumin, the final concentration of the latter in the preparation being equal to 5%. Animals with analogous blood loss replaced by PSS alone served as control. Infusion of the preparation under study led to a steady recovery of the main parameters of the hemodynamics disordered as a result of blood loss. Its infusion to experimental animals was followed by a noticeable increase in oxygen blood capacity, provoked a more considerable elevation of pO2 in arterial and venous blood as compared to control. Compensation with PFS emulsion for homeostatic changes that occurred in dogs after blood loss involved a more active oxygen utilization, whereas in controls, a more considerable increase of cardiac output. The study drug is offered as base for a blood substitute-oxygen carrier.
