JP. Thouvenot (Groupe d’Etudes en Nutrition Infantile - CHJPurpan 31059 Toulouse C6dex France.) The metabolic effects of a taurine-supplented dietary formula in infants on the synthesis and the conjugaticm of bile acids remain uncertain. 16 children, received an artificial nutrition necessitated by a digestive disease. At the beginning of the present study, they were 6 to 16 wks-old, in good nutritional state, witkut malabsorption, protein-losing enteropathy, liver or infectious disease signs. They had the same semi-elemental defined fornula diets adapted to their requirements. The infants received at least 8 days this diet without taurine, followed immediately by 8 to 21 days of the same regimen supplementedby taurine (36 to 45 umol/kg/2+ h). Bile swles ware obtained by duodenal tube, after at least 8 days of diet without i taurine (Pl ; n-10)) and 8 dqS CP2; n-lo), 15 to 20 days (P3 ; n-6) of a taurine supplementeddiet. Total bile acid IN), taurocholic acid (TA), taurochenodeoxycholic acid (I’CRA), taurodeoxycholic acid acid YTW ,glycocholic acid (GA),glycocbenoaeaxycholit acid (CXIIA),glycodeoxy&lic (GCA)and unconjugated bile acid (UN) contxmtration$weremeasuredby enzymaticmethods after thin-layer chraaatography (a~l/l). The glyco and tauro conjugates ratio (G/T) was evaluated. The following results were obtained (m Z Sar). TBA
