  • The increased AST and ALT activities of rat serum disturbed by $CCl_4-intoxication$ intoxication were significantly inhibited by silymarin and biphenyl dimethylene dicarboxylate at the oral doses of 150 and 5 mg/kg, respectively. The combined administration of the drugs showed remarkable inhibition of the enzyme activities. This fact may suggest that the two drugs have potentiative action in this experiment.

  • Objectives and Methods : Salviae miltiorrhizae Radix (SMR) promotes blood circulation to remove blood stasis, cools the blood to relieve carbuncle, clears away heat from the heart and tranquilizes the mind. This study was designed to investigate the effects of SMR on immuno-potentiative action in terms of changes in the genetic profile of dendritic cells (DC) using by microarray analysis. Results and Conclusion: In this experiment, treatments with more than 250 ${\mu}g/ml$ upto 1000 ${\mu}g/ml$ of SMR elevated the proliferation rates of DC. Microscopic observations confirmed the tendency on proliferation rates. Expression levels of genes related with cellular methabolic process, cell communication, and macromolecule metabolic process were elevated by treatment with SMR in comparison of functional distribution in a Biological Process. In molecular functions, expression levels of genes related with receptor activation, nucleotide binding and nucleic acid binding were elevated. In cellular components, expression levels of genes related to cellular membrane-bound organelles were elevated. In addition, expression levels of genes related to Wnt signalling pathways and the glycerophospholipid metabolism were elevated through analysis using pathway analysis between up-and down-regulated genes in cells treated with SMR. Finally, genes related to JAK2, GRB2, CDC42, SMAD4, B2M, FOS and ESRI located the center of Protein interaction network of genes through treatment with SMR.

  • Yeum et al. formulated a new hot-plate method using the threshold temperature, and there are some controversies on the effects of naloxone and diazepam on the antinociceptive action. In this paper, the comparison of three methods registering analgesic activity and the application of the new hot-plate method formulated by Yeum et al. on the study of the influences of naloxone and diazepam on the analgesic effect of morphine were tried in male mice. The results obtained were summarized as follows; 1) The least-square regression lines of the morphine analgesia plotted against log-dose showed the correlation coefficient of above 0.90, but the competitive antagonism produced by naloxone (0.1 mg/kg) against the analgesia was more prominently demonstated by the new hot-plate method than the other methods: original hot-plate method and electrical stimulation method. 2) In the experiment using the new hot-plate method, the log dose-response curve of morphine (y=7.30 x+49.80, r=0.998) was shifted to the right by the pretreatment of naloxone (0.1 mg/kg), but was slightly shifted to the left by the pretreatment of diazepam (2.5 mg/kg). This study suggests that for the analgesia experiment, the new hot-plate method is superior to the original hot-plate method or the electrical stimulation method, and that the potentiative effect of diazepam on the morphine anagesia is not significant.
