Investigation of Spectrum-effect Relationship of Brain Protection of Shaoyao Gancaotang on Epileptic Mice Based on Grey Correlation Analysis / 中国实验方剂学杂志

Objective:To investigate the spectrum-effect relationship of effect of material components in Shaoyao Gancaotang on the levels of malondialdehyde (MDA), superoxide dismutase (SOD) and adenosine triphosphatase (ATPase) in brain tissue of epileptic mice, and to reveal the material basis of the antiepileptic effect of Shaoyao Gancaotang. Method:HPLC was used to establish the fingerprint of 15 batches of Shaoyao Gancaotang, the mobile phase was consisted of acetonitrile (A)-0.1% phosphoric acid aqueous solution (B) for gradient elution (0-15 min, 19%A; 15-45 min, 19%A-50%A; 45-46 min, 50%A-90%A; 46-48 min, 90%A), the flow rate was 1.0 mL·min-1, and the detection wavelength was 237 nm. The mouse epilepsy model was induced by penicillin, the protective effect of 15 batches of Shaoyao Gancaotang on MDA, SOD and ATPase levels in brain tissue of epileptic mice was investigated. Grey correlation analysis was used to analyze the correlation between the peak areas of characteristic peaks in the fingerprint of 15 batches of Shaoyao Gancaotang and three pharmacodynamic indexes (the activities of MDA, SOD and ATPase), and the mathematical model of spectrum-effect relationship between different material components and pharmacodynamic indexes was established. Result:Shaoyao Gancaotang could increase the contents of ATPase and SOD and reduce the content of MDA in the brain tissue of epileptic mice, and most of the differences were significant (P<0.05, P<0.01). There were 28 common peaks in the fingerprint of 15 batches of Shaoyao Gancaotang, and 15 of them were characteristic peaks. Grey correlation analysis found that the characteristic peaks contributed to the activities of MDA, SOD and ATPase included peak 2 (albiflorin), peak 3 (paeoniflorin), peak 5 (liquiritin), and so on, the specific ranking was peak 3>peak 6>peak 12>peak 8>peak 2>peak 5>peak 9>peak 4>peak 10>peak 7>peak 13>peak 11>peak 15>peak 1>peak 14. Conclusion:Shaoyao Gancaotang can affect the activities of SOD, MDA and ATPase in brain tissue of epileptic mice by multi-component synergy. Simultaneously, introducing the grey correlation analysis into the correlation evaluation of the spectrum-effect relationship between components and efficacy of Chinese herbal compounds, it can objectively reflect the essence of the synergistic action of multiple components in traditional Chinese medicine (TCM), and it is an effective analysis method for screening and predicting the pharmacodynamic components of TCM.

Observe effect of treating C-IBS by Tongyouqing / 中国中药杂志

<p><b>OBJECTIVE</b>To explore the effect of Tongyouqing treating the C-IBS.</p><p><b>METHOD</b>According to rome standard II, fifty-eithy C-IBS patients were randomly divided into two groups. Control group (28 cases) were given tijiaseluo (6 mg, qd). Treatment group (30 cases) were given Tongyouqing. After treatment for 4 weeks, observing and comparing the two groups IBS symptom between treatment before and later (Bristol score, abdominal distention, abdominal angina, constipation, partial defecation, belch, mind). To understand the condition of the colonic dynamic by colonic transit trial. Comparing the effective rate of the two group and the proportion of patients still choosing the medicine which they were given.</p><p><b>RESULT</b>The symptom score of the two groups patients, there were signifi-cant differences between the two groups before treatment and after treatment (P <0.05). After treatment, treatment group is prefer to control group in the improvement of the colonic dynamic (P <0.05). The effective rate and the proportion of patients still choosing the medicine which they were given of treatment group is also more higher than control group.</p><p><b>CONCLUSION</b>Tongyouqing can relieve the gastrointestinal symptom, improve the fecal character, lessen abdominal distention and abdominal angina, increase the defecating times, improve the colonic dynamic, improve the mind state quilkly and manifestly. Tongyouqing is an effective method to treat C-IBS. It deserves clinical spreading, its mechnism needs further study.</p>

Study on characteristics of seed germination of Salvia officinalis / 中国中药杂志

<p><b>OBJECTIVE</b>To investigate the influences of lightness and temperature on seeds germination of Salvia officinalis, and offer the basis for the standardized cultivation of S. officinalis.</p><p><b>METHOD</b>The morphological characters, 1 000-grains weight and rate of water absorption of the seed were observed, the germination capacity, percent of germination power and germination index at the five different degrees: 10, 15, 20, 25, 30 degrees C were also measared.</p><p><b>RESULT</b>1 000-grains weight of the seeds was 8.03 g, the rate of water absorption is 49% within 24 h, the highest rate of germination capacity reached 85.33%, the germination index is 45.56.</p><p><b>CONCLUSION</b>The lightness and 25 degrees C are the most suitable parameters for the seed germination of S. officinalis.</p>
