Tidskriftsartikel (refereegranskat) abstract
The aim of the present study was to identify in a standardized experimental rat liver tumor system the drugs which are most appropriate in influencing the relationship between liver tumor and normal liver parenchyma blood flow as estimated with 133Xe washout clearance method, and thereby positively influencing the kinetics of chemotherapeutic drugs. A battery of vasoactive drugs, which according to a literature review were considered to be active, were tested.

133Xe clearance estimates the effect of vasopressin on peritoneal blood flow in rats.

When assessing the peritoneal microcirculation with invasive methods, interference with the mechanisms of vaso-regulation may occur. The 133Xe clearance technique renders the possibility, by minimal invasiveness, to estimate the influence of a vasoactive agent on the peritoneal microcirculation.

Tidskriftsartikel (refereegranskat) abstract
Intraperitoneal administration of 5-fluorouracil for the treatment of gastrointestinal malignancies results in a greater total drug exposure in the peritoneal fluid than in plasma. Drugs are eliminated from the peritoneal cavity mainly by capillaries leading to the portal venous system and to a lesser extent by lymphatics. The drug itself and the presence of peritoneal carcinomatosis may affect elimination of the drug. The 133Xe-clearance technique allows the influence of a vasoactive agent on the peritoneal blood flow to be estimated with minimal invasiveness. The aim of the present study was to explore whether intraperitoneal 5-FU or peritoneal carcinomatosis affects the peritoneal blood flow and its reactivity to intravenous vasopressin, as measured indirectly with the 133Xe-clearance technique.
