The selective monoamine oxidase B inhibitor selegiline was used as a positive control drug. After successive administration for 4 weeks, Herba Epimedii could downregulate the expression of caspase-3 and increase the brain-derived neurotrophic factor level, as well as increase tyrosine hydroxylase activity in the substantia nigra of Parkinson's disease mouse models. Rhizoma Polygonaticould downregulate the expression of caspase-3 and FasL, and increase neural growth factor and brain-derived neurotrophic factor levels. Fructus Ligustn Lucidi could downregulate caspase-3 expression. Rhizoma Polygonati and Fructus Ligustn Lucidi did not produce obvious effects on tyrosine hydroxylase activity. Herba Epimedii and Fructus Ligustri Lucidi yielded similar effects on apoptosis-promoting factors to those elicited by selegiline. Herba Epimedii and Rhizoma Polygonati significantly increased the levels of neurotrophic factors compared with selegiline. Herba Epimedii significantly increased tyrosine hydroxylase activity compared with selegiline. It is indicated that the kidney-tonifying Chinese herbal preparation can downregulate the expression of apoptosis-promoting factors, increase neurotrophic factors levels in the substantia nigra and striatum, as well as increase tyrosine hydroxylase activity in the substantia nigra of Parkinson's disease mouse models, thereby exerting a stronger or similar neuroprotective effects compared with selegiline.展开更多

Administration of beryllium per se caused severe degenerative and necrotic changes in liver, kidney, lungs and spleen. Its administration reduced glycogen content, activity of alkaline phosphatase and adenosine triphosphatase in these oreans. On the contrary, activities of acid phosphatase and glucose-6-phosphatase were increased singificantly. In Liv-52 primed rats significant recoupment was observed in all the parameters展开更多

[ Method] The "Quxie" ( i. e. eliminating pathogenic factors) drugs including Hedyotis diffusa and Loni- cera japonica and "Fuzheng" ( i. e. strengthening body resistance) drugs including Radix astragali and Glycyrrhiza uralensis were taken to form an antiviral herbal compound preparation. Taking the astragalus polysaccharide monomer as control, the experiment was constructed by using the agent to treat some naturally occurring viral diseases, including Newcastle disease (ND), infectious bursal disease (IBD), duck viral hepatitis (DVH), avian influenza (Al) H9 subtype and avian swollen head syndrome. [Ressult] The effective rates of the agent for treatment of the above- mentioned diseases were 87%, 87%, 69%, 100% and 100%, respectively, which were higher than that of astragalus polysaccharide monomer. The cure rates for these diseases were 33%, 37%, 13%, 69% and 75%, respectively, which were significantly higher than that of astragalus polysacchadde monomer ( P 〈 0.01 ). The rates of poor therapeutic efficacy were 15%, 21%, 24%, 6% and 7%, respectively, which were significantly lower than that of astragalus polysaccharide monomer (P 〈 0.01 ). [ Condusion] The Chinese herbal compound preparation shows good therapeutic effects on some avian viral diseases, which can decrease mortality rate and improve production performance of poultry more greatly than astragalus polysaccharide monomer.展开更多
