The paper examines the intonation of monosyllabic Hungarian yes-no questions, which, according to the literature, is different from the intonation of polysyllabic Hungarian yes-no questions. The paper's conclusion is that the difference is only phonetic, not phonological. From a phonological point of view, such questions carry a rising-falling intonation pattern, just like their polysyllabic counterparts. This is proved by the facts of contour concord, which we can observe between the melodies of so called equivalent blocks in Hungarian sentences (Varga 2002, 100-2). From a phonetic point of view, however, the falling part of the abstract rising-falling pattern is normally truncated, leaving only a rise. The final fall (in the form of a downglide) is optionally preserved in surprised monosyllabic yes-no questions, when the syllable has a long vowel in it, able to accommodate the downglide.

A szerzők egy 35 éves nőbeteg kórtörténetét ismertetik, akinél 29 éves korában szeronegatív rheumatoid arthritist igazoltak a reumatológiai osztályon. A betegség remisszióját sikeres graviditás követte, majd két évvel később kizárólag axiális tüneteket mutató spondylarthritist diagnosztizáltak. A major hisztokompatibilitási komplex vizsgálata során a hagyományos szerológiai módszerekkel a HLA B27 spondylarthritis ankylopoeticára jellemző, valamint HLA DR1 rheumatoid arthritisre jellemző haplotípust mutattak ki. A HLA DRB-polimorfizmus vizsgálata során a rheumatoid arthritis létrejöttében és kórlefolyásában szerepet játszó HLA DR B1 0101 allél jelenlétét igazolták. A betegben tehát ritka kombinációként a spondylarthritis ankylopoetica és a rheumatoid arthritis létrejöttében is szerepet játszó HLA-formáció egyaránt megtalálható volt.

Numerous Fusarium species have been associated with the Fusarium head blight (FHB) disease of wheat, barley and other small-grain cereals, reducing worldwide cereal crop yields and, as a consequence of their mycotoxin production in the cereal grain, having an impact on both human and animal health.The year 2010 was extremely favourable for Fusarium head blight pathogens. Over a hundred symptomatic wheat heads were collected from various locations in Hungary. The aim was to determine the diversity of the Fusarium species infecting winter wheat ears. A total of 86 Fusarium spp. were morphologically identified from diseased kernels. F. sambucinum was found to be present in two of the Martonvásár samples. This pathogen had only previously been detected extremely sporadically. The species F. culmorum and F. verticillioides were found at a much lower rate than expected, while none of the isolates were identified as F. poae. On the basis of the results, 95% of the isolates belonged to the Fusarium graminearum species complex.

Az obstruktív alvási apnoe szindróma a felnőtt lakosság számottevő részét érintő, súlyos cardiovascularis szövődményekkel járó és a betegek életminőségét jelentősen rontó megbetegedés. A krónikus obstruktív tüdőbetegség szintén a középkorú korosztály legmagasabb prevalenciájú megbetegedései között szerepel. E két, népbetegségként számon tartott légúti szindróma együttes fennállása súlyos, kombinált alvás alatti légzészavart eredményez. Krónikus obstruktív tüdőbetegségben szenvedő betegek esetében az alvási apnoe fennállásának mielőbbi felismerése és a kevert légzészavar adekvát kezelése alapvető fontosságú. Orv. Hetil., 2012, 153, 892–897.

Three new serotypes were found among Rhodococcus equi strains, which could not be assigned into any of the seven serotypes of Prescott’s system. Fortythree R. equi strains out of 44 previously nontypable ones isolated in Hungary could be allocated into one of the three new serotypes using the agar gel immunodiffusion (AGID) test. The three new suggested serotypes are serotype 8 (proposed reference strain: HNCMB-138003), serotype 9 (proposed reference strain: HNCMB-138004) and serotype 10 (proposed reference strain: HNCMB-138005). Hyperimmune sera produced in rabbits against the new serotypes and reference strains gave precipitation only with their homologous antigens, and no crossreactions were observed. All of the previously nontypable isolates from clinical samples of horses (lung abscesses, intestinal lymph nodes, mediastinal lymph nodes) proved to be serotype 8, while strains of serotypes 8, 9 and 10 could be isolated from nasal and rectal swabs of horses and from the soil. Serotype 9 dominated among the previously nontypable strains of swine origin. One of the previously nontypable human strains was serotype 10. This serotype was also isolated from pigs, horses and the soil. The description of the three new serotypes can help us reveal new correlations between the host species, geographical origin and serotype of R. equi isolates.

Two hundred and twelve Rhodococcus equi strains were isolated from soil, nasal and rectal swabs of horses and immunocompromised human patients in Hungary and serotyped using Prescott’s serotyping system. One hundred and forty-seven strains (69.3%) belonged to serotype 1, 22 strains (10.4%) to serotype 2, 6 strains (2.8%) to serotype 3 and 1 strain (0.5%) to serotype 4. Serotypes 5, 6 and 7 were not found and 36 strains (17%) could not be typed. Serotype 1 (72%) was the type most commonly isolated from clinical samples of foals or from the soil of horse facilities. Six out of 8 R. equi strains from humans belonged to serotype 2, and two human strains were untypable. The data show that the prevalence of R. equi serotypes varies in different geographic areas of the country.

The purpose of this study was to develop and evaluate an aerosol infection method with Histophilus somni that closely resembles the natural way of infection of calves. Another aim was to compare the virulence of two H. somni strains by collecting clinical and postmortem data of experimentally infected and control animals. Seventeen conventionally reared 3-month-old calves were divided into three groups. Two groups of six animals each were exposed to suspensions containing H. somni on three consecutive days using a vaporiser mask. The third group of five animals was used as control. The data of individual clinical examination were recorded daily. All animals were exterminated, and gross pathology of all lungs was evaluated on the 15th day after the first infection. Both H. somni strains caused an increase of rectal temperature, respiratory signs, decrease of weight gain, and severe catarrhal bronchopneumonia in both infected groups. Although some chronic lesions were detected in the lungs of the control animals as well, the histopathological findings in the infected and control groups were different. H. somni was recultured from all lungs in the challenged groups but it could not be reisolated or detected by PCR examination in the control group. This is the first paper on aerosol challenge of calves with H. somni using repeated infection and verified by detailed pathological, bacteriological and histopathological examination. The infection method proved to be successful. There was no difference in the virulence of the two H. somni strains used in the trial.

A betegek tartós anticoagulans kezelésére gyakran választjuk az acenocumarolt. A gyógyszer túladagolása esetén a szervezet különböző helyein bevérzés keletkezhet. Három betegünknél különleges helyen, a rectus abdominis területén figyeltük meg suffusiók kialakulását. A jelenség diagnosztikus nehézséget okozhat, mivel a panaszok kezdetekor a hasfal bőrén elszíneződés nem látszik. A kórok megállapítását az anamnaesisben szereplő tartós véralvadásgátló-szedés segíti. A tapintáskor észlelt nyomásérzékeny hasfali rezisztencia a gyanút fokozza. A magas INR a haemorrhagiás szövődmény lehetőségét támogatja. Egyszerű esetben a diagnózis az anamnaesis, a tapintás, az INR és az ultrahang alapján felállítható. A bonyolultabb esetek tisztázásában a CT segíthet, de egyik betegünknél csak laparoscopiával jutottunk pontos diagnózishoz. A csökkent plazma-prothrombinszintet K-vitamin adásával minden esetben normalizálni tudtuk.
