[A study of Laminaria digitata powder on experimental hyperlipoproteinemia and its hemorrheology]

Twenty rabbits with experimental hyperlipoproteinemia were divided randomly into two groups. The first group was administered Laminaria digitata powder (1 g daily) for 14 days. Another was given only the routine menu. It was found that the Laminaria digitata had a significant effect of lowering total cholesterol, -lipoprotein, especially triglyceride (P less than 0.01), meanwhile it could increase the level of HDL-c and HDL2-c. Also it could reduce relative blood viscosity, relative plasma viscosity, reductive viscosity and fibrinogen very significantly (P less than 0.01). However HDL3-c, hematocrit and index of erythrocytic deformability were not much influenced (P greater than 0.05). This experiment showed that there was a connection between the blood lipids and the concept of "Phlegm" in TCM.
