ABSTRACT
Objective:
To study the anti-lipopolysaccharide (LPS) effect of the ultrafine granular powder of Houttuynia cordata and the effects in comparison with traditional decoction pieces.Methods:
BALB/c mice were injected with LPS through nose to establish lung inflammation model. The number of leukocytes in mice whole blood was examined, and the degree of the inflammation of lung tissue by pathology was observed. Rat inflammatory model was induced by injection of LPS into tail vein. The number of leukocytes in mice whole blood, content of LPS in plasma were examined, the content of IL-1β, IL-6, and TNF-α in serum were detected by enzyme-linked immunoadsordent assay (ELISA). The limulus test method was used to detect the anti- lipopolysaccharide effect of the ultrafine granular powder of H. cordata in vitro.Results:
The ultrafine granular powder of H. cordata and traditional decoction pieces can reduce the level of leukocytes in mice whole blood in various degrees, and alleviated the infiltration of inflammatory cells in pathological lung tissue, and there was a positive dosage dependent relation. For the two decoction pieces, the number of leukocytes in rat whole blood, the content of LPS in plasma, the levels of IL-1β, IL-6, and TNF-α in serum decreased in different degrees were found. Compared with traditional decoction pieces group, the content of IL-1β and TNF-α of serum in ultrafine granular powder group were significant decreased. The ultrafine granular powder of H. cordata showed better anti-inflammatory activity than traditional decoction pieces in vitro at the same concentration and same dilution ratio.Conclusion:
The ultrafine granular powder of H. cordata has satisfactory anti-lipopolysaccharide effect, and the effect is better than traditional decoction pieces in some extent.
