[Role of ultrasound dopplerography with acute captopril test in assessment of renal hemodynamics in chronic glomerulonephritis].

Aim: To examine blood flow in renal and intrarenal arteries and its changes in the acute pharmacological test with captopril in patients with chronic glomerulonephritis (CGN).

Material And Methods: Renal circulation was studied in 50 patients with CGN using ultrasound dopplerography (USDG) of renal vessels on the unit GE Logiq 400 CL PRO Series. The velocity and indices of peripheral blood resistance in the major renal artery (RA) and in intrarenal arteries were estimated.

[Primary glomerulopathies: incidence, dynamics and clinical manifestations of morphological variants].

4400 biopsies studied in the pathology department of I.M. Sechenov Moscow Medical Academy in 1970-1999 were analysed.

[A statistical morphological analysis of cirrhosis and primary liver cancer (based on autopsy data from the clinics of the I. M. Sechenov 1st Moscow Medical Institute)].

Liver cirrhosis (LC) comprises 2.1% of 17,458 autopsies in the pathology department for the period from 1962 to 1987, the incidence has increased during the last decade. LC is more frequent in males than in females (ratio 1.

[The morphological characteristics of hepatocyte dysplasia].

Two variants of dysplastic hepatocytes are revealed: small and large which are characterized by cell atypia and probably result from the disturbance of regenerative processes. The disturbance of the liver lobule architectonics is also a feature of dysplasia. The degree of hepatocyte dysplasia assessed by morphometric indices (nuclei surface, ratio of ellipticity) and its frequency increase with progression of the pathological process: chronic persistent hepatitis----chronic active hepatitis----liver cirrhosis----hepatocellular carcinoma.
