[The ultrasonic diagnosis of renal tuberculosis]. / Ul'trazvukovaia diagnostika tuberkuleza pochek.

Informative value of ultrasonography potential in the diagnosis of nephrotuberculosis was studied by comparison with conventional x-ray and intraoperative findings in 78 relevant patients. Three patterns of renal ultrasonic architectonics changes in nephrotuberculosis were revealed: 1) focal heterogeneity of renal parenchyma, 2) pseudocystic type, 3) hydronephrotic transformation. It is concluded that ultrasonography is superior to routine diagnostic methods, but is recommended for use in combination with standard methods of phthisiourological diagnosis.

[The role of echo scanning of the kidneys in the diagnosis of acute pyelonephritis]. / Rol' ékhoskanirovaniia pochek v diagnostike ostrogo pielonefrita.

The role of echo scanning in the diagnosis of acute pyelonephritis was evaluated in 123 patients. It was established that ultrasonography in acute pyelonephritis is a highly informative diagnostic method. The importance is high in acute obstructive pyelonephritis and less informative in acute non-obstructive pyelonephritis. The method has no equal counterparts in the most difficult cases for diagnosis. Association of renal echo scanning with traditional method significantly increases the diagnosis quality.

[Immunity and the possibilities for immunomodulation in acute pyelonephritis]. / Sostoianie immuniteta i vozmozhnosti immunomoduliatsii pri ostrom pielonefrite.

The paper presents evidence on dysfunction of natural killer cells and abnormal proliferative response of peripheral blood mononuclears to T- and B-cell mitogens (PHA, Phytolacca) in patients at varying stages of acute pyelonephritis. A number of immunomodulators (recombinant alpha 2-interferon, IL-2 and tactivin) produce different effects on natural killer activity and lymphocyte blast transformation in healthy donors and pyelonephritis patients. Immunotropic effects of immunopeptides depend on the drug dose, the response of various subpopulations of the immunocompetent cells being individual. It is suggested that immune system, natural killer activity in particular, plays an important part in pathogenesis of acute pyelonephritis. In vitro experiments demonstrate that there can be a positive clinical response to tactivin and recombinant alpha 2-interferon administered in doses activating the function of certain immunocompetent cells.

[Acute pyelonephritis and the immunity status]. / Ostryi pielonefrit i sostoianie immuniteta.

The quantitative and functional state of different populations of immunocompetent cells was studied in 45 patients with acute serous and 46 patients with acute purulent pyelonephritis. An imbalance has been found in the system of regulatory cells, activation of phagocytosis with reduction of its reserve capacities, disorders of IL-producing capacity of mononuclears and suppression of the functional activity of NK cells.
