    Notes: Abstract A comprehensive evaluation of the automated haematology analyser Contraves AL 820 was initiated to determine the suitability of this instrument for veterinary purposes in domestic, pet and laboratory animal species. The AL 820 (AVL Medical Instruments, Schaffhausen, Switzerland) is an impedance cell counter with automated threshold setting for rapid adaptation to cell characteristics of different animal species. Storage capability for up to 200 data sets with histograms is provided. Excellent precision, linearity and carry-over features of the AL 820 have been demonstrated in tests with rat, mouse, cat, dog, cattle and horse blood samples. Accuracy of haemoglobin and haematocrit measurements with respect to reference methods was characterised by strong linear correlation. The patented cyanide-free AL 820 method for haemoglobin determination compared very well to the haemoglobincyanide reference method. Accuracy of the red blood cell, haemoglobin, haematocrit, mean corpuscular volume, white blood cell count and platelet count parameters was generally good, when compared to the established laboratory routine method (the predecessor model AL 801) or to a high end automated haematology analyser (Abbott Cell-Dyn CD 3500). Although variation of platelet count measurements was greater than variation of all other parameters, it was considered acceptable particularly with respect to the lack of excelling alternatives. Poor accuracy of feline platelet counts was attributed to overlapping size distribution of red blood cells and platelets in this species. The overall favourable acceptance of the AL 820 was based on easy handling, simple maintenance and pronounced flexibility of this instrument at an economical purchase price. A sample volume of 30 µl and a throughput of up to 60 samples per hour are distinct advantages and render the AL 820 suitable for medium-sized laboratories. With few exceptions, the instrument provides reliable results for all major animal species encountered in routine veterinary haematology.

    Description / Table of Contents: Zusammenfassung In der vorliegenden Studie wurden die 1991/92 mittels Wiegeprotokoll-Methode über 3 Tage in Erfurt erhobenen Daten von 422 Männern und 315 Frauen im Alter zwischen 20 und 64 Jahren analysiert. Der Bundeslebensmittelschlüssel, Version 2.1, wurde zur Kodierung der Lebensmittel und zur Berechnung der Inhaltsstoffe herangezogen. Die Darstellung der Ergebnisse erfolgte mittels altersstandardisierter Mittelwerte. Nichtraucher beiderlei Geschlechts verzehrten z.B. mehr frisches Obst (m: 166 g vs. 119 g, p=0,0001; w: 180 g vs. 147 g, p=0,0009), mehr Milch und Milchprodukte (m: 195 g vs. 121 g, p=0,0108; w: 176 g vs. 136 g, p=0,0004) und tranken weniger Kaffee (m: 401 g vs. 457 g, p=0,0103; w: 387 g vs. 491 g, p=0,0003) als Raucher. Als Folge nahmen Raucher beispielsweise weniger Ballaststoffe sowie wenige ausgewählter Vitamine und Mineralstoffe auf. Diese Ergebnisse aus einer ostdeutschen Population entsprechen denen anderer industrialisierter westlicher Länder.
    Notes: Summary Data relating to 422 men and 315 women aged 20 to 64 years were collected in 1991/92 using 3-day weighed records. The national German food composition file BLS 2.1 was used for food coding and calculation of nutrients. Age adjusted mean daily intakes were presented. Food intake habits of smokers and non-smokers showed distinct differences: for instance, non-smokers of both genders ate more fresh fruit (m: 166 g vs. 119 g, p=0.0001; f: 180 g vs. 147 g, p=0.0009), more milk and milk products (m: 195 g vs. 121 g, p=0.0108; f: 176 g vs. 136 g, p=0.0004), and drank less coffee (m: 401 g vs. 457 g, p=0.0103; f: 387 g vs. 491 g, p=0.0003). As a result, intakes of various nutrients also differed. For example, smokers had lower intakes of fibre, selected vitamins, and minerals. The tendency toward an unhealthier dietary pattern in smokers was in accordance with findings from various industrialized Western countries.
