Toxicological evaluation of fenugreek seeds was made in 60 NIDDM subjects in a 24 week study in which changes in body weight, clinical signs and symptoms and serum parameters such as SGOT, SGPT, alkaline phosphatase, bilirubin, creatinine and blood urea, together with haematological parameters, was

โฆ Synopsis
Groups of 15 male rats were fed ad libitum for 4 weeks standard diet containing 0, 2.5, 5 or 10% rapeseed protein isolate (RPI), 2.5, 5 or 10% rapeseed extraction residue (RER) or 10% casein. Body weight gain and food intake were recorded weekly. Clinical chemistry analyses, haematology, urinanalysis, organ weights and histology were performed terminally. Serum alanine aminotransferase was decreased by RPI, RER and casein, while serum albumin only increased in rats fed RER. Microscopic examinations revealed abnormalities in liver and kidneys of animals at the 10% RPI, RER and casein levels. The absolute liver weights showed increases in the 5 and 10% RER groups and in the 10% RPI group. The relative kidney weights were reduced at all RER levels and in the 2.5% RPI group. Antithyroid activity of the rapeseed products were not noted.
Zusammenfassung
Toxikologische Bewertung von Rapssamen-Produkten in einem subakuten Fiitterungsversuch rnit Ratten Gruppen von 15 mannlichen Ratten erhielten ad libitum uber einen Zeitraum von 4 Wochen eine Standard-Diat rnit 0, 2,5, 5 oder 10% Rapssamen-Protein-Isolat (RPI), 2,5, 5, oder 10% Rapssamen-Extraktions-Riickstand (RER) bzw. 10% Casein. Wochentlich wurden Korpermasse und Futteraufnahme registriert. Am Ende des Versuchs wurden klinisch-chemische, hamatologische und Urin-Analysen sowie Organmassebestimmungen und histologische Untersuchungen durchgefuhrt. Die Aktivitat der Alanin-Aminotransferase des Serums wurde durch RPI, RER und Casein vermindert. RER bewirkte eine Zunahme des Serumalbumingehalts. Die mikroskopischen Auswertungen erbrachten Abnormitaten in der Leber und in den Nieren bei Tieren, die 10% RPI, RER und Casein im Futter erhielten. Die absolute Lebermasse war bei den Tieren rnit 5% und 10% RER sowie bei den Tieren rnit 10% RPI in der Diat erhoht. Bei allen Tieren, die RER erhielten sowie in der Gruppe mit 2,5% RPI waren die relativen Nierenmassen erniedrigt. Antithyroide Effekte lieljen sich nicht nachweisen.
