    Notes: Summary Hepatic function was assessed by the aminopyrine breath test (ABT) in male Sprague Dawley rats 24 h after partial hepatic ischemia. ABT decreased progressively to 26.3 (p〈0.05) and 19.7% of dose (p〈0.05) after 90 and 120 min of ischemia, respectively. ABT at 24 h after injury was correlated to the concentration of ATP in the ischemic lobes 1 h after the onset of reperfusion (r2=0.971) but not to ALT activity in plasma at 1 h (r2=0.391). We conclude that postischemic ATP levels are a better index of subsequent hepatic function than ALT.

    Notes: Summary The gastrointestinal absorption of lactitol has been studied in 6 healthy volunteers and 8 patients with cirrhosis. Following administration of lactitol 0.5 g/kg, no lactitol was found in serum. The urinary excretion of lactitol over 24 h ranged from 0.1 to 1.4% of the administered dose (0.46% in cirrhotics and 0.35% in healthy volunteers). Blood D- and L-lactate and plasma glucose did not increase following lactitol. The data indicate that lactitol was poorly absorbed from the gastrointestinal tract in healthy volunteers and patients with cirrhosis, and that the disaccharide did not disturb glucose or lactate homeostasis.

    Notes: Summary The chronic use of lactitol as a food additive or laxative might adversely affect calcium homeostasis. Its effect on calcium metabolism has been examined in an open cross-over study in 12 volunteers given 20–40 g lactitol per day for one month. Compared to a control period without lactitol, the disaccharide did not alter the urinary excretion of calcium, inorganic phosphate or hydroxyproline, nor did it alter the circulating levels of calcium, phosphate, alkaline phosphatase, parathormone and osteocalcin. Chronic treatment with lactitol in laxative doses had no measurable effect on calcium metabolism in man.
