[Management of maxillofacial injuries under extraordinary conditions].

The authors analyze the most important conditions of the management of patients with maxillofacial injuries in disaster circumstances. Under extraordinary conditions the injuries are frequently complex therefore the establishment of a precise diagnosis is difficult, and one must reckon with the lack of time caused by the occasionally large number of patients to be managed. Under extraordinary conditions the management of maxillofacial injured can only be solved with compromises.

[Effect of homogenized human pathogenic Helicobacter pylori on the viability of isolated rat gastric mucosal cells].

Aim of this study was to detect the possible direct cellular effect of Helicobacter pylori (Hp) (obtained by biopsy from patients with gastric and duodenal ulcer) on freshly isolated rat gastric mucosal cells. Urease test positive Hp cultured from human biopsy sample was sonicated and incubated with freshly isolated rat gastric mucosal cells. The direct cellular damaging effect of Hp was evaluated alone and in combination with ethanol and indomethacin. The cellular damaging effect was tested morphologically (Trypan blue exclusion) and biochemically (measurements of lactate dehydrogenase, succinic dehydrogenase and ethidium bromide DNA fluorescence). Hp alone, or in combination with ethanol and indomethacin had no direct cellular toxicity on freshly isolated rat gastric mucosal cells. The isolated and cultured Hp collected from human beings did not produce any cellular damage on freshly isolated rat gastric mucosal cells.

[The importance of professional cooperation in the management of orbital injuries].

The injuries of the maxilla and the mandible are usually composite, often requiring the close cooperation of professionals of various specialties. In the Central Military Hospital the authors have set up a team for the complex diagnostic and therapeutic management of patients with orbit injuries. The organizational aspects and basic principles of the team work are dealt with.

[Management of patients with maxillofacial injuries at the Oral Surgery Department of the Hungarian Central Military Hospital (analysis of a 10-year patient material)].

The authors have worked up the most important data of as many as 500 patients with malar and mandibular bone injuries. It is established that these injuries mostly derive from aggressive actions and traffic accidents. During this decade the ratio of injuries regarding the mandible and centre of the face has changed from 2.5:1 to 1:1. Since January 1, 1994 the number of managed injured patients has significantly increased, as a consequence of the maxillofacial service connected into the duty management in Budapest.

Protein profile typing--a new method of typing Morganella morganii strains.

A new, simple and stable method for typing Morganella morganii strains is described. The 150 strains examined, principally from faeces, contained haemolytic and non-haemolytic representatives of diverse O serogroup, bacteriocin type and biotype. Among the biotypes were some trehalose-fermenting, tetracycline-resistant strains and some non-motile, tetracycline-sensitive, glycerol fermenters. After analysis of cell lysates by sodium dodecyl sulphate-discontinuous polyacrylamide gel electrophoresis, strains could be differentiated into 21 types on the basis of outer membrane proteins (OMP) of 35-40 Kda. The OMP profile was not altered by culture on various common media and was unrelated to either O antigen or morganocin p-type. The finest strain recognition in M. morganii can be achieved by application of all three distinct typing methods.

New O antigens of Morganella morganii and the relationships between haemolysin production. O antigens and morganocin types of strains.

A collection of 142 strains of Morganella morganii, principally from unrelated patients' faeces was examined to determine the relationship, if any, between haemolysin production, O antigen and morganocin production/sensitivity type. Only 55 (38.7%) were agglutinable with the existing 44 O antisera. However, when O antisera were raised to some of the non-typable strains 11 new O antigens were found and 126 (88.7%) of the strains were typable. The number of O antigenic groups in M. morganii is now 55. It was confirmed that the O antigenic characteristics of strains were independent from morganocin producer types. An epidemiological retrospective survey showed that finer strain recognition in M. morganii can be achieved by using both methods than either method alone. Approximately 30% of strains were haemolytic. The ability to produce haemolysin was more common in strains of certain O serogroups and morganocin producer types than in others.

Haematological reactions of rabbits infected intravenously with Listeria strains of different virulence.

Listeria strains of different virulence were injected intravenously into rabbits of both sexes (2-4 kg). The infectious dose was 10(8) cells/kg. Blood samples were taken from the ear wein one day and immediately before the infection, then 3 h, 1, 2, 3, 6 and 10 days after it. Total white blood cell counts and their changes were determined and the number of lysosomal granules in neutrophils were counted. A marked monocytic reaction was observed after the injection of virulent Listeria monocytogenes 18 and 87/5467, partly virulent Listeria ivanovii, non-pathogenic Listeria seeligeri 87/5626 and 87/5575, and Listeria murrayi G44 strains. A late slow growth was provoked by Listeria innocua C644 and a very slight reaction by Listeria welshimeri 1830 strains. There was no change after injection of L. innocua strain 10. The number of lysosomal granules decreased significantly and remained at a low level for 6 days after the infection of L. monocytogenes strain 18 and for 3 days after the injection of L. innocua strain 10.

Discovery of new morganocin types of Morganella morganii in strains of diverse serotype and the apparent independence of bacteriocin type from serotype of strains.

A collection of 45 serologically distinct strains of Morganella morganii from several European countries was typed by morganocin production (p) and sensitivity (s). This permitted their differentiation into 33 morganocin p/s types; 15 new types of morganocin and one new morganocin sensitivity type were found and are defined. Morganocin production and sensitivity characteristics appeared to be unrelated to the O and H antigens of the strain. The finest strain recognition in M. morganii might be achieved by a combination of bacteriocin and serotyping methods.

Toxic shock syndrome toxin-1 (TSST-1) production in staphylococcal infections and serological implications with patients and healthy controls.

TSST-1 production occurred in 4.6% among Staphylococcus aureus strains isolated from divergent clinical sources in South-West Hungary. Patients suffering from staphylococcal infections, whether or not harbouring TSST-1 positive strains, exhibited low anti TSST-1 titres in their acute phase sera compared to the healthy control population. A S. aureus strain isolated from toxic shock syndrome (TSS) was a high collagen binder and a low fibronectin and fibrinogen binder suggesting the role of connective tissue adhesion in colonization and low invasive property of TSS strains.

Modified enzyme-linked immunosorbent assay for detecting enteroinvasive Escherichia coli and virulent Shigella strains.

Immune sera were produced in rabbits with living cells of an enteroinvasive O143 strain of Escherichia coli. To remove O and K antibodies, sera were absorbed with an avirulent derivative of the same strain. In the enzyme-linked immunosorbent assay, absorbed sera reacted specifically with only virulent Shigella strains and enteroinvasive E. coli strains of different geographical origin, regardless of species or serogroups. The investigation of 83 strains indicated complete agreement between enzyme-linked immunosorbent assay results and those of the keratoconjunctivitis test. It is assumed that the absorbed immune sera reacted with a possible virulence marker antigen. This inexpensive and simple method provides an alternative to other virulence tests. It has a definite advantage for screening large number of isolates within 24 h.

New serotypes of Morganella morganii.

On the basis of 8 new O and 11 new H antigens determined in 22 strains, the Morganella morganii antigenic schema was supplemented with 8 serogroups (O35-O42) and 13 serotypes. Four strains belonged to O groups described earlier and 2 strains contained new O antigens in combination with known O antigens. Known H antigens were present in one strain as a single factor and in one strain as combination of two factors. New H antigens were demonstrated in 5 serotypes in combination with known H antigens. Six out of the 22 isolates were classified into O group 35. Two isolates contained different B-type surface antigens; these factors were not related to Escherichia coli B antigens and, unlike the latter, their living suspension gave a higher titre agglutination in OK serum as compared to the boild culture.
