Liposome-encapsulated hemoglobin (LEH) was administered intravenously to rats and plasma samples were taken at intervals from 10 up to 180 min after injection. The samples displayed increased free Hb and thromboxane B2 levels, decreased complement hemolytic titers and increased lytic activity on glucose-containing liposomes in an in vitro assay. In vitro studies showed that traces of phospholipase A2 activity, present in hemoglobin (Hb), were amplified 20 to 300-fold when co-encapsulated with Hb in liposomes. There is a possibility that a causal relationship exists between lysolecithin production and transient hemodynamic and hematological effects of LEH in rats.
