Q: Abstract: The occurrence of fever during various blood purification methods was evaluated in a retrospective study. It could be demonstrated, that patients treated chronically by conventional hemodialysis experience six times more febrile episodes than patients on chronic hemofiltration (4.84% versus 0.81%). Since many of the increased temperatures could not be explained by conventional means, it has to be assumed that the treatment itself caused the fever, possibly activating the monocyte hormone interleukin 1. It is of further note that there was no difference in the magnitude of the temperature due to septicaemia or to no obvious cause. This finding necessitates in our opinion an early antibiotic therapy in those cases where fever develops without clear explanation.

Q: Abstract: Human and experimental colitis are associated with release of both vasoconstrictor and vasodilator eicosanoids. To determine the pattern of colonic blood flow in vivo and the role of prostaglandins and thromboxanes, immune complex-mediated colitis and delayed hypersensitivity-mediated colitis were induced in rabbits. Organ blood flow was determined in conscious animals by radiolabeled microspheres before and after cyclooxygenase or thromboxane synthetase inhibition. Colonic blood flow was twofold higher in colitis than in control animals. Thromboxane synthetase inhibition with dazoxiben caused a slight further increase of colon perfusion in animals with colitis, but thromboxane receptor blockade had no effect. Prostaglandin inhibition with indomethacin and ibuprofen did not affect blood flow in controls, but in animals with colitis these drugs markedly reduced colonic blood flow to the level of control animals. The data demonstrate that vasodilatory prostaglandins enhance colonic blood flow in acute colon inflammation.

Q: Abstract: Suspension of living hepatocytes were microencapsulated inside 300 micron mean diameter alginate artificial cells. The galactosamine fulminant hepatic failure rat model was used. 48 hours after the injection of galactosamine, grade II coma hepatic failure rats were divided into pairs. One of the pair was randomly chosen for the control group, and the other for the treated group. Each rat in the control group received one peritoneal injection of microcapsules containing no hepatocytes. Each rat in the treated group received one peritoneal injection of microcapsules containing hepatocytes. The survival of the treated group is significantly higher than the control group.

Bioartificial liver: implanted artificial cells microencapsulated living hepatocytes increases survival of liver failure rats.
