title: Lymphoid tissue responses to perfluorocarbon emulsion in mice.
abstract: The effects of either intraperitoneal or intravenous injection of low doses (5 or 10 ml/kg) of the proprietary emulsified perfluorocarbon-based blood substitute, Fluosol-DA 20%, on mouse lymphoid tissue and antibody production against sheep erythrocytes (SRBC) have been investigated. Mean liver weight was significantly increased and gut mesenteric lymph node (MLN) weights decreased in all animals injected with Fluosol-DA, irrespective of route of administration. In contrast, spleen weight decreased following intravenous injection of emulsion at 5 ml/kg. The mean plasma haemagglutination response to SRBC was significantly (P less than 0.01) increased in animals injected intraperitoneally with Fluosol at both doses but was similar to control in all other cases. These results show that lymphoid tissue responses to Fluosol-DA in mice are variable and that antibody production against intraperitoneally-injected SRBC is enhanced by prior injection of emulsion into the peritoneal cavity.
