[The course and prognosis of mesangioproliferative glomerulonephritis].

Aim: A retrospective analysis of a clinical course of mesangioproliferative glomerulonephritis (MPGN) in patients with glomerular deposition of IgA (IgA nephropathy--IgA-N), with glomerular deposition of other Ig to determine prognostic factors of MpGN progression including IgA-N and to examine the patients' sensitivity to immunodepressive therapy.

Material And Methods: 2000 patients with primary MPGN followed up from 1980 to 1999 from the disease onset to development of chronic renal failure (creatinine > 2.5 mg%).

[Renal and uterine hemodynamics in pregnant women with hypertension].

Aim: To study gestational alterations of renal and uterine hemodynamics, their relationships with systemic and intracardiac hemodynamics in pregnant women (PW) with essential hypertension (EH).

Material And Methods: Echocardiography, ultrasound dopplerography of renal and uterine arteries, roll-over test were made in the course of trimester II-III and 3 months after the delivery in 48 PW with EH degree 1-2 and control 20 healthy PW. Hemodynamic parameters in pregnancy were compared to postpartum ones.

Correlation between the expression of DNA topoisomerases I and IIalpha and clinical parameters in kidney disease.

Multiple factors interact during the evolution of renal diseases. In the present study, we examined the expression of DNA topoisomerases type I and IIalpha, which reflect gene transcription and DNA replication, respectively. Enzyme content was assessed by immunohistochemistry using two specific monoclonal antibodies, C21 and Ki-S4, on 81 archival punch-biopsy specimens from patients with renal diseases, including minimal change disease (MCD; n = 10), focal segmental glomerular sclerosis (FSGS; n = 6), mesangial proliferative glomerulonephritis (MPGN; n = 11), membranous glomerulonephritis (MGN; n = 10), mesangial capillary glomerulonephritis (MCGN; n = 7), rapidly progressive glomerulonephritis (RPGN; n = 12), lupus nephritis (LN; n = 15), and tubulointerstitial nephritis (TIN; n = 10).
