Analgesic Effect of Different Extraction Process of Taohong Siwu Decoction and Its separating Prescription / 中药新药与临床药理

Objective To compare the analgesic effect of Semen Persicae (SP, Taoren), Flos Carthami (FC, Honghua), Siwu Decoction (SD) and Tao Hong Siwu Decoction (THSD) in dysmenorrhea model and the acetic-acid-induced pain model. Methods The dysmenorrhea model and the acetic-acid-induced pain model were established, and the pain threshold was compared in different mice models. Results On dysmenorrheal model, the analgesic effect of water extract supernatant and ethanol suspension of FC, SP polysaccharide, water extract supernatant and ethanol extract of SD, SD and THSD polysaccharide differed from that of blank control. On acetic-acid-induced pain model, the analgesic effect of water extract supernatant and ethanol suspension of FC, FC polysaccharide, ethanol extract of SP, SP polysaccharide, SP+ FC water extract, SP+ FC ethanol extract, SP+ FC polysaccharide, SD ethanol extract, SD polysaccharide, THSD water extract and ethanol extract, and THSD polysaccharide differed from that of blank control. Conclusion FC water extract and ethanol extract, SP ethanol extract, THSD polysaccharide, SD ethanol extract and SD polysaccharide have the best analgesic action, and then come with THSD water extract and ethanol extract, SP + FC ethanol extract, and SP + FC polysaccharide.

Study of Reagents of Biotin-Avidin System and Their Applications Ⅴ.The Detection of Antibodies to Cell Surface Antigens with ABC-ELISA / 中国免疫学杂志

Two reaction systems have been observed to ascertain the capability of ABC-ELISA on the detection of antibodies against particulate antigens.Mouse thymucytes as the antigens were coated on the enzyme immunoassay plate for one system,and rabbit anti- mouse brain serum was titrated.The titer of the serum in ABC-ELISA was 1:12,800, about 40-fold higher than that in complement dependent cytotoxicity assay.In the other system,the plate was coated with cultured human leukemia cells of T lymphocyte origin(Cem-T)and B cell origin(Daudi),where the ascites induced by an anti-human lymphocyte hybridoma was titrated.The results showed that ABC-ELISA was 8-16 times sensitive than the standard ELISA,while the specificity and reliability of ABC- ELISA seemed satisfectory.The experi mental condition that might reduce nonspeci- ficity of the reaction to a certain degree was discussed.
