[Autoantibodies against lipoprotein(a) in patients with coronary heart disease].

Objective: Lipoprotein(a) - Lp(a) is an independent risk factor of atherosclerosis and its complications. In spite of the long period of Lp(a) research there is no complete understanding of its physiological role and atherogenic action. The goal of this study was to investigate the presence in human plasma of circulating autoantibodies to Lp(a) belonging to different classes of immunoglobulins, and to elucidate their relationship to the presence and severity of coronary atherosclerosis in middle aged patients with coronary heart disease.

[Effect of cascade plasma filtration on spectrum of subfractions of low density lipoproteins in blood plasma of patients with ischemic heart disease].

We studied effect of cascade plasma filtration on subfractions of low density lipoproteins (LDL) in 16 patients with ischemic heart disease (IHD) and hyperlipidemias refractory to drug therapy. The procedure caused 37.6 ± 1.

[Treatment of bile ducts injuries after laparoscopic cholecystectomy].

Features of bile ducts injuries after laparoscopic cholecystectomy were analyzed at 54 patients. High level of lesions (H. Bismuth III-IV type) was revealed at 80% cases.

[Effect of promethazine hydrochloride (pipolphen) on the stability of R plasmid resistance in Escherichia coli].

The influence of promethazin hydrochloride (pipolphen) on stability of R plasmid inheritance in Escherichia coli strains of various serogroups was studied. The strains were isolated from patients with acute intestinal infection and from healthy persons. It was shown that in subbacteriostatic concentrations (100 to 450 micrograms/ml) pipolphen promoted elimination of the R plasmids.

[Complications after endoscopic interventions on the major duodenal papilla].

An analysis of 83 cases of complications following endoscopic procedures on the major duodenal papilla was made: 62 cases after 2110 retrograde cholangiopancreatographies (RChPG) and 21 after 620 endoscopic papillosphincterotomies (EPST). Among most frequent complications there were acute pancreatitis (49 cases), purulent cholangitis (11 cases), suppurations of the pancreatic cysts and purulent pancreatitis (8 cases). Bleedings took place after EPST in 11 patients.
