The aim of this study was to compare four identification procedures to detect Dichelobacter nodosus and develop a rapid, simple and effective method to identify D. nodosus strains isolated from cases of ovine footrot. The four methods used were: (a) the classic guidelines set down by Holdeman et al. (1977) and Summanen et al. (1993) which are based on gas liquid chromatography (GLC) and different biochemical tests, this method was considered as landmark; (b) Baron and Citron's flowchart for the rapid identification of Gram-negative rod-shaped anaerobes (1997); (c) the API rapid 32 A system (bio Mérieux), and (d) Mast ID™ Anaerobe ID Ring (MID8) (Mast Diagnostics). None of the four methods used allowed us to correctly identify the D. nodosus strains (neither the strains isolated from cases of ovine footrot nor those originating from type collection). Because of the difficulties encountered in obtaining a correct identification of D. nodosus, we propose a simple, rapid and effective way to achieve this task. Our flowchart will provide the means to identify this microorganism in any laboratory of general microbiology without having to use any specialised equipment.

Background/Aim: There is a limited number of methods to measure blood flow velocity in small veins. A cheap and simple new videomicroscopic method developed in our laboratories is described in the paper.Methods: A stretch of the saphenous vein of the rat was exposed by careful micropreparation on the thigh of anesthetized animals. Bolus amount (approx. 5 μl) of saline was infused into a small side branch through a microcannula to dilute flowing blood. Videomicroscopic picture of the vein was then taken of the exposed upstream stretch of the vein. Serial pictures were digitized and analyzed using macro functions of the Image J software. Sensitive areas of serial pictures were selected and fitted. Consecutive pictures were subtracted from each other to better characterize their alteration in-between frames. Greyscale intensity values measured at different points of the inner diameter were averaged for each point of the vessel axis. Cross-correlations along the axis were then computed for consecutive frames with delays of 40, 80, 120 and 160 msec. Pixel offsets producing cross-correlation maxima were determined and used to compute mean flow velocity.Results: Combination of digital subtraction and cross-correlation computations yielded easily identifiable maximums. Mean flow velocities could be determined with limited uncertainty.Conclusion: The described technique gives a cheap, simple and reproducible mean to determine mean blood flow velocities in small veins in anesthetized animals, where other current techniques (ultrasonography, laser-Doppler, fluorescently labelled red cell movement) are either expensive or can be applied with difficulty only.

A glikált proteinek a glükóz és a fehérjék aminosava között lejátszódó nem enzimatikus reakció termékei. A hemoglobin-A 1c a glükóz és a hemoglobin mindkét béta-láncának N-terminális valinja közötti reakció eredményeként képződik, és a koncentrációja a vörösvértestek életidejének és a vér glükózkoncentrációjának függvénye. Az utóbbinak tulajdoníthatóan az előző 6–8 hét integráltglükóz-koncentrációját jelzi. A HbA 1c -t a glykaemia hosszabb távú monitorozására alkalmas, valamint a diabetes komplikációinak kockázati tényezőjeként is szolgál. A HbA 1c -mérési eredmény az előzőkön túlmenően függ még a vér egyéb szénhidrátjaitól és más alkotóitól, a meghatározási módszertől, illetve annak kalibrálási módjától. Nemzetközi társaságok (IFCC, ADA) dolgoztak ki ajánlásokat (NGSP, DDCT, IFCC) a HbA 1c -meghatározás standardizálására. Az eredmény megadására javasolja az NGSP a százalékot (g HbA 1c /g hemoglobin) és az IFCC az SI egységet (mmol HbA 1c /mol HbA). Több közleményben található olyan statisztikai módszerrel meghatározott egyenlet, amelynek segítségével a HbA 1c -ből az előző 6–8 hét átlagos glükózkoncentrációja (eADAG) megbecsülhető. Az eljárás klinikai relevanciáját több szerző még nem látja teljesen megalapozottnak.
