[The first break-through of the genotype 2.3.2 of high-virulence influenza A virus A/HSN1, which is new for Russia, in the Far East].

The epizootic etiologically associated with highly pathogenic avian influenza H5N1 genotype 2.3.2 that is new for Russia among wild and domestic birds in the south of the Primorye Territory during spring migration in April 2008 has been decoded. About 25% of the wild birds of a water complex, which include European teals (Anas crecca), mallard ducks (Anas platyrhynchos), great-crested grebes (Podiceps cristatus), are involved in viral circulation in the area of the Suifun-Khankai plain. Chicken embryos and the cell lines MDCK, SPEV, BHK-21, SW-13 were used to isolate 3 strains from recently deceased hens (A/chicken/Primorje/1/08, A/chicken/Primorje/11/08, and A/chicken/Primorje/12/08) and one strain from a European teal (A/Anas crecca/Primorje/8/08). The strains were deposited in the State Collection of Viruses of the Russian Federation, D. I. Ivanovsky Research Institute of Virology, Russian Academy of Medical Sciences. The nucleotide sequences of the full-sized genomes of A/chicken/Primorje/1/08 and A/Anas crecca/Primorje/8/08 were sent to the International databank GenBank. The strains from domestic and wild birds were shown to be identical. The isolated strains are most close to the strains Alchicken/Viet Nam/10/05, A/chicken/Guangdong/178/04, and A/duck/Viet Nam/12/05. Molecular genetic analysis has indicated that the strains isolated are susceptible to rimantadine and ozeltamivir and less adapted to mammalian cells (particularly, they contain E627 in RV2, which agrees with the biological properties of these strains in vitro). Penetration of the newly isolated virus into the Far East ecosystem provides in the foreseeable future a way for infecting the birds wintering in America and Australia in the nesting places, with further carriage of viral populations there in the period of autumn migrations.

[Complex environmental and virological monitoring in the Primorye Territory in 2003-2006].

The paper presents the results of monitoring of viruses of Western Nile (WN), Japanese encephalitis (JE), tick-borne encephalitis (TBE), Geta, Influenza A, as well as avian paramicroviruses type I (virus of Newcastle disease (ND)) and type 6 (APMV-6) in the Primorye Territory in 2003-2006. Totally throughout the period, specific antibodies to the viruses were detected by neutralization test in wild birds (7.3%, WN; 8.0%, Geta; 0.7% Batai; 2.8%, Alpine hare (Lepus timidus); by hemagglutination-inhibition test in cattle (11.4% WN; 5.9%, JE; j 3.0%, TBE; 11.6%, Geta), horses (6.1, 6.8, 0, and 25.3%, respectively), and pigs (5.4, 1.5, 0, and 5.9%, respectively) by enzyme immunoassay (IgG) in human beings (0.8, 0.5, 6.8, and 3.2%, respectively. Reverse-transcription polymerase chain reaction (RT-PCR) was used to reveal RNA of the NP segment of influenza A virus in 57.9 and 65% of the cloacal swabs from wild and domestic birds, respectively; and the HA-segment of subtype HH was not detected in 2005. HA/H5 RNA was recorded in 5.5 and 6.7% of the swabs from wild and domestic birds, respectively; 6% of the specimens from domestic birds were M-segment positive in 2006. RNA of influenza A virus NA/H7 and RNA was not detected throughout the years. In 2004, the cloacal swabs 8 isolated influenza A strains: two H3N8 and two H4N8 strains from European teals (Anas crecca), two (H3N8 and H6N2) strains from Baikal teals (A. formosa), one (H10N4) strain from shovelers (A. clypeata), and one (H4N8) from garganeys (A. querquedula). In 2004, one ND virus strain was isolated from the cloacal swabs from European teals (A. crecca). RT-PCR revealed RNA of this virus in some 8 more cloacal swabs from black ducks (A. poecilorhyncha) (3 positive specimens), pheasants (Phasianus colchicus) (n = 2), garganeys (A. querquedula) (n = 1), gadwalls (A. strepera) (n = 1), and geese (Anser anser domesticus) (n = 1). Sequencing of the 374-member fragment of the ND virus F gene, which included a proteolytic cleavage site, could assign two samples to the weakly pathogenetic variants of genotype 1, one sample to highly pathogenic variants of genotype 3a, five to highly pathogenic ones of genotype 5b. Isolation of APMV-6 (2003) from common egrets (Egretta alba) and geese (Ans. anser domesticus) is first described.

[The prevention of the entry of foreign bodies into the stomach and intestines]. / Profilaktika popadaniia inorodnykh tel v zheludok i kishechnik.

On the basis of the results of treatment of 320 patients, the organization and sanitary-instructive measures aimed at prevention of getting, or development of the foreign bodies in the stomach and intestine are suggested. The primary prophylaxis (prevention of penetration of the substances which are alien to the organism into its cavities and tissues) and the secondary one (removal of the foreign bodies from the organism of a patient before their penetration into the intestine) are distinguished.

[Study of tissue reaction to chromium magnetic steel]. / Issledovanie reaktsii tkanei na khromistye magnitnye stali.

For studying tissue reaction to stainless steel of 95Cr18, 01Cr25 brands after vacuum-thermal processing, 01Cr18T and magneto-elastic, the balls and disks of these materials were implanted to 40 experimental animals (rabbits). For comparison, 111Cr15 brand steel and titanium were used. The results obtained permit to recommend the chrome magnetic steel studied for implantation into the human and animal organism.

[Foreign bodies in the rectum and colon]. / Inorodnye tela priamoi i obodochnoi kishki.

On the basis of analysis of treatment of 80 patients with foreign bodies of the rectum and colon, the volume and character of the therapeutic measures required were defined. The endoscopic methods for removal of the foreign bodies, peculiarities of extraction of the large foreign bodies are presented. The cases of penetration of the foreign bodies into the colon via a natural, or artificial intestinal fistula are described.

[Experience with the reflexotherapy of diskogenic pain syndromes]. / Opyt refleksoterapii diskogennykh bolevykh sindromov.

The article presents the results of examination of 304 patients with vertebral osteochondrosis and diskogenic pain who have been subjected to multiple-modality treatment (226 of them had various neurosurgical interventions) including acupuncture and drug therapy. Favourable therapeutic effect was achieved in 72% of the cases. Seventy patients were followed up. The authors present recommendations on the use of acupuncture in practical neurosurgery for the treatment of diskogenic pain.
