  • Dispersion of viable pig liver cells with collagenase
  • 1975

    • Viable suspended hepatocytes were prepared from surgical biopsy specimens of pig and human liver by digestion with collagenase. Initial perfusion of the tissue through cannulated blood vessels with 0.5 mM EGTA followed by 0.2% collagenase gave the best results. 20−870 × 106 cells of which 60–95 % excluded trypan blue were obtained from 5–30 g pig liver pieces, while results with human liver specimens were usually less satisfactory. In some experiments, however, viable cells, as judged by vital stain exclusion and ability to synthesize lipids were obtained in sufficient yield. In the pig hepatocytes glycerolipid synthesis from [3H] glycerol and oxidation and esterification of [14C] oleic acid had the same characteristics as those observed earlier in rat hepatocytes.

  • Alterations of lipid metabolism in healthy volunteers during long-term ethanol intake
  • 1977

    • Nine young, healthy male volunteers were given ethanol (75 g/day) for 5 weeks. The ethanol was divided into five daily doses and taken so that blood ethanol levels never exceeded 0.04% (w/v). During the latter part of the ethanol intake period, there was a significant, transient increase of plasma triglyceride (TG) concentrations followed by reduction to normal levels. A three-fold increase of lipoprotein lipase activity (LLA) occurred in biopsy specimens of adipose tissue. An increase of alpha-lipoprotein concentrations, which correlated significantly with the decrease in plasma TG levels and the increase in adipose LLA, was also observed during the ethanol intake period. No changes were observed in plasma cholesterol and beta-lipoprotein levels. A transient, three-fold increase of TG concentrations occurred in liver biopsy specimens. Ultrastructural and cytochemical examinations of the biopsy specimens showed hyperplasia of the smooth endoplasmic reticulum, and increased canallicular activity of gamma-glutamyl transferase (gamma-GT) activity in most subjects towards the end of and after the ethanol intake period. Serum gamma-GT levels also increased significantly.

  • Interaction by cholestyramine on the uptake of hydrocortisone in the gastrointestinal tract.
  • 1978
  • Ingår i: Acta medica Scandinavica. - 0001-6101. ; 204:6, s. 509-12
  • Tidskriftsartikel (refereegranskat)abstract
    • An absolute reduction of the plasma cortisol levels and a delay of the peak concentrations were recorded in 10 healthy subjects, when a bile-sequestering anionic exchange resin, cholestyramine, was given prior to a single oral hydrocortisone dose, indicating that the resin interferes with the uptake of a neutral sterol in the human gastrointestinal tract. The possibility of a direct binding of drug to resin is supported by the affinity of hydrocortisone to cholestyramine in vitro, which was uninfluenced by the presence of sodium taurocholate. Cholestyramine significantly delayed the gastric emptying of a glucose solution, indicating that the resin not only decreases but also delays hydrocortisone absorption. Careful supervision is recommended when treatment with cholestyramine is given concomitant to neutral sterol drugs.

  • Relief of Pruritus as an Early Sign of Spinal Cord Compression in Hodgkin's Disease
  • 1979
  • Ingår i: Journal of Internal Medicine. - Wiley-Blackwell Publishing Ltd. - 0001-6101. ; 206:1-6, s. 319-320
  • Tidskriftsartikel (refereegranskat)abstract
    • ABSTRACT In a patient with advanced Hodgkin's disease (HD) associated with generalized pruritus, an unexpected relief of itching was found to be an early sign of spinal cord compression. Following irradiation of an extradural mass at the Th II level, itching recurred. Although the mechanisms bringing about itching in HD are unknown, the relief and recurrence of the symptom in our patient are in line with a peripheral origin of pruritus in the disease. Spontaneous relief of pruritus in HD despite other signs of active disease should prompt a neurological examination, since early recognition and treatment of spinal cord compression in lymphoma are important to avoid residual neurological disability. 1979 Association for the Publication of the Journal of Internal Medicine
