Metabolic parameters of the perfused intestine. The relative luminal galactose uptake was measured by a galactose assay kit (a), the lactate-to-pyruvate ratio was evaluated by blood gas analysis and an enzymatic photometric method (b), and the wet-to-dry ratio before (W/d1) as well as after (W/d2) perfusion was calculated (c). Bars denote the mean ± SD. Albumin (N = 6), HES (N = 6), HES/Alb (N = 6) for galactose and wet-to-dry ratio; Albumin (N = 2-6), HES (N = 6), HES/Alb (N = 1-6) for lactate-to-pyruvate ratio. * p < 0.05; ** p < 0.01; *** p < 0.001
