[Methods to increase the accuracy of endoscopic retrograde pancreatic cholangiography in mechanic jaundice].

The results of endoscopic retrograde pancreatocholangiography in 2344 patients with non-tumor extrahepatic scholestasis are analysed. In 90.7%. It was possible to get the information on the disease cause. The diagnosis was based on the results of endoscopic examination, or endoscopic and X-ray examinations. In 84.8% cases the diagnosis was correct, in 5.9% there were diagnostical mistakes. Lack of the proper X-ray information was the major cause of diagnostic problems. The use of endoscopic papillosphincterotomy, instrumental examination of bile ducts, and selective cholegraphy may improve the diagnostic accuracy. The use of these methods is especially indicated in case of serious jaundice, and in acute cholecystitis and pancreatitis. The use of these methods do not increase the rate of complications.

[The prognosis of the nature of the course and outcome of infectious endocarditis].

Prognostic significance of various clinical and laboratory indices for predicting the course and outcome of infectious endocarditis (IE) has been analyzed for 139 IE patients aged 15-68 (77 males and 62 females). The unfavourable prognosis was associated with uncontrollable sepsis, persistence of circulating immune complexes and developing glomerulonephritis. The latter had also prognostic signs unfavourable for IE: moderate or severe proteinuria and/or cylindruria, reduced renal function, diffuse proliferation, pronounced extracapillary and/or tubulointerstitial components.

[The characteristics of cylindruria in patients with chronic glomerulonephritis].

Qualitative and quantitative indices of cylindruria were studied in 325 patients aged from 15 to 64 with various morphological forms of chronic glomerulonephritis (CGN). In 237 of them function of kidneys was unchanged while remaining 88 patients revealed various degrees of chronic renal failure (CRF). Parameters of cylindruria in patients with CGN varied widely, significant correlation having been established between presence of erythrocytic cylinders in urinary residue and degree of haematuria. Large granular cylinders were observed in patients with severe and moderate CRF as distinct from patients with normal renal function and initial stage of renal insufficiency.

[The characteristics of hematuria in chronic glomerulonephritis and nonglomerular diseases of the kidneys and urinary tract].

Upon the analysis of qualitative and quantitative characteristics of hematuria in renal and urinary tract affections it was established that whatever the red blood cell count in the urine, hematuria is primarily glomerular in contrast to nonglomerular in chronic glomerulonephritis and nonglomerular diseases of the kidneys and urinary tracts, respectively. Morphologic studies of urinary red blood cells using phase-contrast microscopy proved a valuable tool for identification of hematuria origin.

[A comparative study of changes in suture materials in mammary gland tissues].

In the experiment on 75 white rats, the reactogenicity and strength of catgut, dexon, kacelon and PGL (native analogue of vicryl) were studied 10, 20 and 30 days after their implantation into parenchyma of the lactating mammary gland (MG). Around a catgut thread, the cellular-tissue reaction according to the type of purulent inflammation occurred. A danger of oncogenic effect of catgut which manifested itself in proliferation and atypical hyperplasia of epithelium of the MG ducts was noted. Dexon, kacelon and PGL were characterized by similar low reactogenicity, but kacelon strength reduced considerably in moistening. Dexon and PGL due to their reactogenicity and strength properties are the materials of choice in surgical treatment of MG diseases.

[Birefringent fat bodies in the urine of patients with primary and secondary glomerulonephritis].

Results are presented of an investigation of birefracting fatty bodies in the urine of patients with primary chronic lupoid and Henoch glomerulonephritis. There was a close correlation between the presence of birefracting fatty bodies and severity of glomerulonephritis independent of the morphological picture of the disease and state of renal function. Reduction of the activity of the disease in the course of pathogenetic treatment characterized by a decrease or disappearance of proteinuria was accompanied by a distinct reduction of the level of birefracting fatty bodies or their disappearance.

[An electron microscopic study of the effector link in immune reactions in stomach cancer].

21 surgically removed gastric carcinomas of different histologic structure and stage of development were studied ultrastructurally. A variety of morphological manifestations of local immune reactions and nonspecific antitumour resistance were observed. These manifestations were characterized by the contacts of lymphocytes, macrophages, polymorphonuclear leukocytes, plasma cells with each other and with tumour cells and by the presence of variable changes in tumour cells. The causes of such a variety are discussed and they may be due to different types of cytotoxicity, stage of the interaction between the effector and the target and so on.

[Minimal change glomerulonephritis in adults].

Glomerulonephritis with minimal alterations presents one of the most complex problems of nephrology. The authors provide the data on the disease incidence and clinico-laboratory correlations in 33 adult patients, discuss problems of the treatment policy.

[The immunological indices in different types of gouty nephropathy and the degree of renal structure involvement].

Patients with different types of podagric nephropathy were examined for 21 indicators of the functional activity of T and B lymphocytes and neutrophils. The data obtained were compared to the degree of impairment of the basic renal structures. Among the study immunologic indicators to estimate the gravity of morphological alterations in the glomeruli, the decrease of the titers of antibodies to DNA is of definite specificity, whereas the fall of the concentration of circulating immune complexes is of definite specificity in the assessment of alteration in the stroma.

[Ultrastructure of breast cancer vessels].

Vascular bed of the infiltrating mammary gland carcinomas characterized by the incomplete maturity, atypia and polymorphism is studied electron microscopically. Two groups of vascular structures were investigated: avascular part represented by pseudovessels and vascular part with protocapillaries, capillaries, sinusoids and venulae that are distinguished by their morphofunctional properties and the degree of maturity. The vascular bed is characterized by a structural and functional heterogeneity. Ultrastructural properties characterizing the stages of the vascular bed morphogenesis are presented: angiogenesis activation, relative vascular differentiation and regression of some parts which occur asynchronically and are due to the properties of the stromal parenchymal relations in different microareas, and to the heterogeneity of the tumour on the whole.

[The effect of pregnancy on the course of different clinical forms and morphological variants of primary chronic glomerulonephritis].

The author relates the data on the time-course of changes in diurnal proteinuria, diastolic arterial pressure and blood creatinine in 123 patients with primary chronic glomerulonephritis seen during 159 pregnancies. The dependence of the character of those changes on the respective parameters before conception was analyzed as was such a dependence, in part of the patients, on the morphological disease pattern. The rise of proteinuria and diastolic arterial pressure during gestation was seen more often in women with initial diurnal protein losses exceeding 1g and with arterial hypertension that occurred before pregnancy. The rise of blood creatinine before conception was a prognostically unfavourable sign. Mesangiocapillary glomerulonephritis occurring in the gestation period is viewed as less favourable as compared to mesangioproliferative glomerulonephritis.
