OBJECTIVE Critically ill patients often develop large gastric residual volumes during nasogastric feeding as a result of poor gastroduodenal motility. Nasojejunal feeding may decrease the severity of this complication. The aim of this study was to determine whether nasojejunal feeding improved tolerance of enteral nutrition by reducing gastric residual(More)
The longevity of recipients of liver transplant may be compromised by spinal osteoporosis and vertebral fractures. However, femoral neck fractures are associated with a higher morbidity and mortality than spine fractures. As there is little information on bone loss at this clinically important site of fracture, the aim of this study was to determine whether(More)
A prevalence study of primary biliary cirrhosis was carried out in the state of Victoria, Australia, by means of a mail survey of specialist physicians and a review of hospital records. Eighty four cases were identified, giving a prevalence of 19.1 per million population (95% confidence limits (CI) 15.3, 23.7), which is among the lowest in published(More)
BACKGROUND In the erythrocytic phase of malaria, Kupffer cells show marked hypertrophy and hyperplasia and are filled with malarial pigment. However, phagocytic function in this state has not been well characterized. The aim of the present study was to use mouse Plasmodium berghei to infect rats with malaria and study the phagocytic function and morphology(More)
The active sodium transport of white cells and red cells obtained from patients with essential hypertension was impaired. Incubating white cells from normotensive subjects in serum obtained from patients with essential hypertension caused an impairment in sodium transport in the white cells of normotensive subjects similar to that found in the white cells(More)
1. The hepatic reticulo-endothelial cell population is generally assumed to increase in size, along with the liver, during ageing in rats. However, this has not been rigorously established. 2. Using electron microscopy and stereological techniques, the present study has shown that the volume densities of hepatocytes and Kupffer cells (and probably also of(More)
Uptake from the circulation and subsequent intracellular degradation of foreign and potentially harmful substances are key functions of hepatic Kupffer cells. While ageing is generally associated with decreased clearance by the reticulo-endothelial system, the effect of ageing on specific Kupffer cell functions is poorly understood. This study measured the(More)
BACKGROUND AND AIM Previous studies using isolated perfused rat liver in vivo have suggested that during the erythrocytic phase of malaria infection, overall phagocytosis by Kupffer cells is enhanced. The aim of the present study was to further investigate the individual phagocytic capacity and prostaglandin E(2) (PGE(2)) secretion of isolated Kupffer cells(More)
Previous studies have demonstrated abnormalities of intracellular electrolyte content and sodium transport in leukocytes of patients with fulminant hepatic failure. The current study was undertaken to establish whether similar abnormalities were present in patients with encephalopathy from advanced cirrhosis. Results from 19 patients with advanced cirrhosis(More)
We tested the hypothesis that apolipoproteins, the protein constituents of plasma lipoproteins, are secreted into bile. We examined human gallbladder bile obtained at surgery (N = 54) from subjects with (N = 44) and without (N = 10) gallstones and hepatic bile collected by T-tube drainage (N = 9) after cholecystectomy. Using specific radioimmunoassays for(More)
