    Description / Table of Contents: Summary The fatty acid composition of the fat in 197 food samples has been analyzed by gas liquid chromatography. The use of a 30 m capillary column coated with CP™Sil88 permitted the separation of the cis and trans isomers. The trans fatty acid content of milk and milk products ranged from 1.9 to 7.9 %. Meat samples from ruminants contained 2.0–10.6 % trans fatty acids. In pork fat the amounts were less than 0.5 %. Sausages and other meat products contained high levels of pork fat. Therefore these samples contained less than 1 % trans fatty acids, with the exception of some pure beef products. The amounts of trans fatty acids in foods which may contain hydrogenated oils ranged from 0 to 34.9 %. In food samples with high levels of trans fatty acids lower contents of saturated fatty acids were analyzed.
    Notes: Zusammenfassung Die Fettsäurezusammensetzung von 197 Lebensmitteln wurde gaschromatographisch untersucht. Cis- und trans-isomere Fettsäuren wurden auf einer mit CP™Sil88 belegten 30 m Kapillarsäule getrennt. In Milch und Milchprodukten lagen die ermittelten Gehalte an trans-isomeren Fettsäuren zwischen 1,9 und 7,9 %. Im Fleisch von Wiederkäuern wurden 2,0–10,6 % trans-isomere Fettsäuren gefunden. Im Schweinefleisch lagen die Gehalte unter 0,5 %. Entsprechend der überwiegenden Verwendung von Schweinefleisch wiesen Fleischwaren mit Ausnahme der allein aus Rindfleisch hergestellten Produkte niedrige trans-Fettsäuregehalte von kleiner 1 % auf. Die trans-Fettsäuregehalte von Lebensmitteln aus Produktgruppen, in denen gehärtete Pflanzenfette eingesetzt werden, zeigten Gehalte zwischen 0 und 34,9 %. Lebensmittel mit hohen trans-Fettsäuregehalten enthielten geringere Anteile gesättigter Fettsäuren.

    Description / Table of Contents: Summary The intake of trans octadecenoic acids is estimated by a national consumption assay. The daily intake in West Germany differs between 3,4 g for women und 4,1 g for men. The consumption of trans fatty acids decreased in the last years, due to the progress in food technology and changes in nutritional habits. The main sources of trans fatty acids are partially hydrogenated vegetable fats just as well as ruminant and dairy fats.
    Notes: Zusammenfassung Die Aufnahme von trans-Octadecensäuren in der Bundesrepublik Deutschland (alte Bundesländer) wird anhand der nationalen Verzehrsstudie abgeschätzt. Sie beträgt für Frauen 3,4 g/Person und Tag und für Männer 4,1 g/Person und Tag. Die Aufnahme ist in den letzten Jahren aufgrund veränderter Verzehrsgewohnheiten und verbesserter Technologien zurückgegangen. Hauptquellen der trans-Fettsäureaufnahme sind neben den teilgehärteten Pflanzenfetten, das Fett und die Milch der Wiederkäuer.

    Notes: Summary Forty-eight specimens of carcinoma of the floor of the mouth were analyzed histologically by step serial sections. Five tumors were so-called superficial spreading carcinomas with large fields of cancerous mucosa, while 43 specimens showed advanced vertical growth into adjacent structures. Three different routes of invasion could be defined. The region of the sublingual gland was the main pathway in 23 cases. The space between the intrinsic muscles of the tongue and the genioglossus muscle was the main direction of infiltration for 14 tumors. Only 6 specimens showed direct invasion into the intrinsic tongue muscles. There was a good correlation between tumor thickness and the occurrence of metastases. Twenty-six patients (54%) showed metastases in regional lymph nodes and 13 patients with submandibular metastases already had developed metastases along the jugular vein. Unilateral or bilateral functional neck dissections remained the standard treatment procedure for all cases with depths of invasion over 5 mm. To avoid local tumor recurrences, patterns of invasion have to be considered. Soft tissue structures like the sublingual gland, intrinsic tongue muscles, genioglosssus muscle and geniohyoid muscle have to be resected routinely. Management of the mandible should be conservative if radiological and clinical investigations are negative.
