Kobayashi, A., Utsunomiya, T., Ohbe, Y., and Nagashima, Y. (1974). Archives of Disease in Childhood, 49, 90. Intestinal absorption of calcium and magnesium in hepatobiliary disease in infancy. The intestinal absorption of calcium and magnesium was measured by metabolic balance studies in 6 normal infants, 13 infants with biliary atresia, 5 infants with successfully repaired biliary atresia, 7 infants with neonatal hepatitis, and 2 infants with choledochal cyst. The absorption of both elements was impaired in these disorders. The malabsorption of these elements was most marked in biliary atresia. In successfully repaired biliary atresia the absorption was increased to the normal levels. In neonatal hepatitis the degree of the malabsorption was variable in individual cases. In choledochal cyst the reduction of the absorption was less marked than in biliary atresia and neonatal hepatitis. In biliary atresia parenteral vitamin D increased moderately the absorption of both elements, though oral vitamin D had little effect. In infants with biliary atresia receiving a milk containing medium-chain triglycerides the absorption was moderately raised. There was a clear relation between the absorption of calcium and that of magnesium: the per cent. absorption of magnesium was almost the same as that of calcium in most cases. The serum calcium level determined during the studies was within the normal ranges in hepatobiliary diseases. The serum magnesium level was, however, found to be generally reduced in these conditions. It was greatly reduced in the patients with biliary atresia.

Background and Objectives: calcium is the most abundant mineral in the body, making up nearly 2% of total body weight. This element has several roles in organisms. Manganese is an essential trace element which is taken part in the structure of some metal enzymes. There is a little evidence for deficiency of manganese in human, whereas its toxicity has been reported in several cases. Since, ca...

For 4 weeks, 3-month old germfree (GF) and conventional (CV) rats were given a semi-synthetic diet sterilized by irradiation with or without 10% of lactose. During the 5th week, 0.2% of titanium oxide (TiO2) was added to the diet and the rats were killed at regular intervals throughout the light/dark cycle. The patterns of TiO2 and 45Ca excretion were similar, indicating that TiO2 was a good ma...
متن کاملAbsorption of calcium and magnesium in patients with intestinal resections treated with medium chain fatty acids.
BACKGROUND Steatorrhoea is associated with increased faecal loss of calcium and magnesium. Medium chain C8-C10 triglycerides (MCTs) improve fat absorption in patients with small bowel resections but the effects on intestinal absorption of divalent cations are not clear. AIM To assess the effect of dietary replacement of long chain triglycerides (LCTs) with MCTs on calcium and magnesium absorp...
