The effect on mucosal pathohistological grading was 2.00±0.84 and 0.91±0.46 in mild UC (P〈0.001), and 2.49±0.84 and 1.31±0.75 in moderate UC (P〈0.001) before and after treatment.CONCLUSION: SASP can improve small vessel lesions and crypt abscesses and reduce neutrophilic and eosinophilic leukocyte infiltration in inflammatory mucosa of UC.展开更多

Methods: The growth-thermogram curves of Escherichia coli (E. coli) affected by Shexiang (Moschus) and Bingpian (Borneolum Synthcticum) at different concentrations were determined with microcalorimetry, and the power-time curves (thermogram curves) of E. coli metabolism and characteristic parameters, such as growth rate constant (k), maximum output power (Pm), peak time (tp), total heat-output (Qt), etc. were analyzed with the principal component analysis (PCA) to find the close correlative parameters, so as to objectively reflect the drug property differences of Shexiang (Moschus) and Bingpian (Borneolum Synthcticum). Results: The values of P2 in the second exponential growth phase increased with the increase of the concentrations of Shexiang (Moschus) and Bingpian (Borneolum Synthcticum), and the P2 of Shexiang (Moschus) was larger than that of Bingpian (Borneolum Synthcticum); Q2 increased with the increase of the concentrations of Shexiang (Moschus), but for Bingpian (Borneolum Synthcticum) it was opposite. It is indicated that they have different effects on P2 and Q2 of E. coli in the second exponential growth phase, and have differences in warm and cold natures. Conclusion: The microcalorimetry can accurately and objectively appraise differences of the drug property of Shexiang (Moschus) and Bingpian (Borneolum Synthcticum) and verify the objectivity and authenticity of the drug property, so as to provide a new and useful method for studies of the drug property of Chinese drugs.展开更多
