ABSTRACT

BACKGROUND: Herbal wines are an important part of the traditional Chinese medicine. The traditional medicated wine, lishizhen herbal wine,which can strengthen the immune function, has long been used for some chronic diseases. But,its mechanism remains unclear.OBJECTIVE: To explore the immune pharmacodynamics of lishizhen herbal wine and to observe its effect on the immune organs (spleen,pancreas) and lymphocyte transformation rate in mice.DESIGN: A randomized controlled experiment based on the observation of the experimental animals.SETTING: Department of integrated traditional Chinese and western medicine and the department of pharmacology of a university hospital MATERIALS: The experiment was completed at the Central Laboratory of Zhongnain Hospital of Wuhan University from September 2000 to December 2000. A total of 90 healthy Kuming mice were involved in the study.METHODS: Different doses of the herbal wine,cartinellin and the same volume of distilled water were given to the experimental animals. The drug administration was orally injected directly to the stomach of the animals once a day and 10 days consecutively. One hour after the last administration,the animals were put to death. Then,the thymus gland and the spleen were taken out and weighed to calculate the indexes of the thymus gland and the spleen. In the last three days of the administration phytohemagglutinin(PHA)was injected intramuscularly at a dose of 10 mg/kg once per day. Two hours after the last administration, the tails of the mice were cut out, the blood samples were taken to perform the Wright' s staining,and 100 lymphocytes were counted under immersion and the transformation rate was calculated.MAIN OUTCOME MEASURES: Primary results: ① The effect on the immune organs of normal mice; ② The effect of PHA on stimulating the lymphocyte transformation in mice. Secondary results: ③ The death condition of the experimental animalsRESULTS: Different doses of the herbal wine increased the spleen index in different degrees. The effect of medium dose group was obvious[(3.71± 0.78) g/kg] (P <0.05),and the thymus gland index increased a little (P>0.05). The cartinellin in the positive control group increased the spleen index[(3.79±0.91 ) g/kg] and there was no impact on thymus gland index. The transformation rates of the lymphocytes of different groups were increased to a different degree and presented a good quantity-effect relationship,especially the group administered a large dose[(45±14)%] (P<0. 01).CONCLUSION: Lishizhen herbal wine has an effect of increasing cellular immune function.

ABSTRACT

Objective To observe the effect of short wave diathermy on the functioning of dendritic cells ( DCs) derived from the spleens of hepatitis B virus ( HBV) transgenic mice. Methods HBV transgenic mice were treated with short wave diathermy for 10 days. Dendritic cells were then separated from their spleens and incubated with granulocyte-macrophage colony-stimulating factor ( GM-CSF) and interleukin-4 ( IL-4 ). The phenotypes of the DCs were assayed by flow cytometry ( FCM) ,IL-12 released by the DCs and IL-10 and IFN-? produced by the T cells in a mixed lymphocyte reaction( MLR) were measured using ELISA. Results Short wave diathermy could enhance the DCs' phenotype expression, increase IL-12 levels ( P
