[Helicobacteriosis of the operated stomach in peptic ulcer]. / Gelikobakterioz operirovannogo zheludka pri iazvennoi bolezni.

After Billorth-II resection of the stomach for ulcer the contamination of the stump with Helicobacter pylori (HP) was detected in 73.7% of the cases, for ulcer of the duodenum--in 81.8% of the patients. At later terms after selective proximal vagotomy (SPV) all the patients were HP-positive, after SPV with draining operations 92.3% of the patients were HP-positive. The degree of inflammatory alterations in the mucosa was proportional to the degree of its bacterial dissemination. The HP contamination of the gastric mucosa after operation had no marked influence on the clinical course of the remote postoperative period. Spontaneous elimination of HP was observed in 42.9% of the patients with the developing achlorhydria of the operated stomach.

[The development and certification of the Hepabest anti-HBc IgG test system for detecting antibodies to the core antigen of the hepatitis B virus]. / Razrabotka i aprobatsiia test-sistemy "Gepabest anti-HBc IgG" dlia vyiavleniia antitel k korovomu antigenu virusa gepatita B.

The comparison of the newly developed "HepaBest anti-HBc IgG" assay system for the detection of hepatitis B virus (HBV) core antigen with the reference system "ImmunoComb HBc IgG" (Orgenics, France-Israel) and its approbation on 91 serum samples from patients in the Infectious Clinical Hospital were carried out. The coincidence rate of the results obtained with the use of the two assay systems was 87.9%. The system "HepaBest anti-HBc IgG" permitted the detection of patients whose sera contained no other HBV markers, except anti-HBc IgG. This assay system may be recommended for use in clinical and epidemiological investigations for ascertaining the diagnosis.

[Prevalence of serological markers for viral hepatitis B and C in patients and medical personnel in the hematologic ward of Novosibirsk city hospital No. 2]. / Vstrechaemost' serologicheskikh markerov virusnykh gepatitov B i C patsientov i meditsinskogo personala gematologicheskogo otdeleniia gorodskoi bol'nitsy No. 2 Novosibirska.

Blood samples of 60 patients and 19 staff members were tested for serological markers of hepatitides B (HBV) and C (HBC) using the Vector-Best JSC enzyme immunoassay kits. HBV and HBC markers were found in 25 in 30% of patients and in 15.8 and 5.3% of staff members, respectively. Part of the sera with HBV and HBC markers were tested for the HBV and HBC RNAs by polymerase chain reaction. The findings confirm that donors should be more thoroughly tested for hepatitis markers, as well as the patients and staff of hematology departments.

[Frequency of encountering markers of viral hepatitis A, B, and C in the aboriginal inhabitants of the northwest region of Siberia]. / Chastota vstrechaemosti markerov virusnykh gepatitiv A, B, C u korennogo naseleniia severa zapadnoi sibiri.

A minor population of Nenets living near the village of Samburg in the Purov District, Tyumen region was screened for serological markers of virus hepatitides A, B, and C (VHA, HVB, and HVC, respectively). Commercial kits manufactured by VectorBest JSC, Russia, were used. All the tested sera contained antiHVA IgG; IgM antibodies to VHA were detected in none of the tested sera, anti-HVC IgG were found in 1 (0.93%) serum, antiHBc IgG in 11 (10.2%), and HBsAg was detected in 2 (1.85%) serum samples. The sera positive by antiHBc IgG and HBsAg were tested for DNA by the polymerase chain reaction. HVB DNA was found in two HBsAg-positive sera with the HBsAg subtype determined as "non ad".

[Microbial cenosis in the initial stage of spruce needle decomposition]. / Mikrobnoe soobshchestvo v nachal'noi stadii razlozheniia khvoia eli.

The formation of saprophytic microbial cenosis at the primary stage of decomposition of spruce needles was studied by the method of scanning electron microscopy with parallel inoculations into growth media. The composition of the cenosis was found to differ depending on whether the needles were decomposed on the surface of the forest floor or on the soil without any flooring. The characteristics of the formation of the saprophytic microbial cenosis are described. The cenosis is formed from individual species of the soil microbial complex and from some representatives of the epiphytic microbial cenosis which change here becoming saprophytes instead of biotrophs. Yeasts and yeast-like organisms predominate at the primary stage of decomposition of spruce needles.
