Respiratory syncytial virus (RSV) has long been considered an important cause of severe lower respiratory tract infection in infants and young children throughout the world. Unfortunately, no effective treatment of RSV exists. Therefore, New agents are needed to reduce the impact of RSV. We have studied the anti-viral effect of traditional Chinese midicinal herbs for over ten years and find Herba Patrinea (a Chinese medicinal herb) has the anti-RSV effect in vitro. In this study, the Herba Patrinea was extracted with hot water, condensed and sterilized. The cytotoxicity of the aqueous extract was tested by adding the diluted extract directly to HeLa cells and its effect on anti-RSV was estimated by the CPEI assay. As a result, the median cytotoxic concentration $(CC_{50})$ of Herba Patrinea was 32 mg/ ml by morphological observation, the median effective concentration (50% effective concentration, $EC_{50}$) of the Herba Patrinea against replication of the Long strain of RSV in HeLa cells were 1.25 mg/ml. The selectivity index $(SI=CC_{50}/EC{50})$ is 25.6. Moreover, Herba Patrinea gave a dose-dependent response in inhibiting RSV. In time of addition experiment, Herba Patrinea inhibited replication of RSV in HeLa cells when it was added at 0h, 2h, and 4h after virus infection. In summary, the results of this study suggest Herba Patrinea may be a novel anti-RSV drug and it is worthy of further studying.

Recent survey shows that chronic liver disease such as chronic hepatitis, liver cirrhosis and hepatoma is the third leading causes for death in Korea. In oriental medicine, viral hepatitis is related to Hwangdal(黃疸) and alcoholic liver disease is related to Joosang(酒傷). ARTEMISIAE HERBA and PUERARIAE RADIX have long been used in treating those symptoms. This study was done to evaluate the effect of AR1EMISIAE HERBA and PUERARIAE RADIX on viral and alcoholic hepatitis. ARTEMISIAE HERBA and PUERARIAE RADIX were decocted respectively with water and followed by vaccum evaporation. The solution was diluted to adequate concentration. Sprague-Dawley rats were used in this experiment. Each group was given PUERARIAE RADIX or ARTEMISIAE HERBA solution orally and CCl4, d-galactosamine or alcohol was given orally 30 minutes later. After 24 hours of starvation, blood samples were taken to check serum GOT, GPT, LDH and ALP activities, TC, TG, glucose and BUN levels. These results show that ARTEMISIAE HERBA has better effect on liver injury induced by d-Galactosamine than PUERARIAE RADIX and that both ARTEMISIAE HERBA and PUERARlAE RADIX have good effect on acute alcoholic liver disease while in the liver injury induced by $CCl_{4}$, PUERARIAE RADIX has better inhibitory effect on serum AST, ALT and ALP levels and ARTEMISIAE HERBA has better inhibitory effect on serum total cholesterol and triglyceride. And the result that high concentration group has better effect shows these effects are concentration-dependent. Further study on the mechanism of these herbs is still required.

Objectives : The purpose of this study was to investigate the antioxidative effects of Ephedrae Herba extract. Methods : Total antioxidant status was examined by total antioxidant capacity(TAC), total antioxidant response(TAR) against potent free radical reactions, total phenolic content, DPPH radical scavenging activities, and the inhibitory effect of the extract on lipid peroxidation in rat liver mitochondria. Results : 1. TAC and TAR of Ephedrae Herba extract at the concentration of 5mg/ml were 3.76 and 1.65 mM Trolox equivalents , respectively. 2. Total phenolic content of Ephedrae Herba extract at the concenuation of 5mg/ml was 3.52 mM gallic acid equivalent. 3. Concentration of Ephedrae Herba extract at which DPPH radical scavenging activity was inhibited by 50% was 0.46mg/ml as compared to 100% by pyrogallol solution as a reference. 4. Ephedrae Herba extract at the concentration of 2mg/ml significantly decreased TBARS concentration by 97%, showing that Ephedrae Herba extract prevented lipid peroxidation at the low concentration. Conclusion : Thus antioxidant effects of Ephedrae Herba extract appear to be due to, at least in part, the prevention from free radicalsinduced oxidation, followed by inhibition of lipid peroxidation.
