ABSTRACT
<p><b>OBJECTIVE</b>To study the protective effects of polysaccharides from Dendrobium huoshanense (DHP) against CCl4-induced liver injury in mice.</p><p><b>METHOD</b>Eighty male Kunming mice were randomly divided into normal control group, model control group, dextran control group, starch control group, hydrolyzate control group, three different dose of DPH groups consisting of high-dosage group, middle-dosage group and low-dosage group (200, 100, 50 mg x kg(-1)). Each group contained ten mice. The mice were treated with DHP via intragastric administration for 15 days before treatment of 50% CCl4 in olive oil for consecutive two days. Both alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities in serum and superoxide dismutase (SOD) activities and malondialdehyde (MDA) contents in liver tissues were determined in all groups. Immunohistochemistry was used to detect the expression of TNF-alpha in hepatic tissue. Hepatic histopathological examination was observed.</p><p><b>RESULT</b>DHP effectively decreased the activities of ALT and AST in serum and the contents of hepatic MDA, and restored hepatic SOD activities in acute liver injury mice. Liver tissue damage induced by CCl4 was ameliorated in mice with DHP administration through histopathology examination. Furthermore, the expression of TNF-alpha was greatly decreased in groups treated with polysaccharides.</p><p><b>CONCLUSION</b>DHP has a significantly hepatoprotective effect on CCl4-induced acute liver injury in mice. Protective effect of DHP on the liver may be related to its function of scavenging free radicals and inhibiting lipid peroxidation and TNF-alpha expression.</p>
