RESUMEN
<p><b>OBJECTIVE</b>To develop a reserved-phase HPLC method for the determination of praeruptorin A, praeruptorin B, qianhucoumarin E in roots of Peucedanum praeruptorum.</p><p><b>METHOD</b>Agilent TC-C18 column (4.6 mm x 250 mm, 5 microm) was used at 30 degrees C with the mobile phase of methanol-water (75:25). The flow rate was set at 0.8 mL x min(-1). The detection wavelength was 321 nm.</p><p><b>RESULT</b>The linear response ranged from 3.20-28.80 microg for +/- praeruptorin A (r = 0.9999, n = 5), 1.60-14.40 g for praeruptorin B (r = 0.9995, n = 5) and 1.64-14.76 g for qianhucoumarin E (r = 0.9994, n = 5), respectively. Recoveries were 98.92% with RSD 1.6% for praeruptorin A, 99.66% with RSD 1.5% for praeruptorin B and 99.72% with RSD 1.4% for qianhucoumarin E.</p><p><b>CONCLUSION</b>The method is quick, simple and repeatable for determination of three coumarin constituents in root of P. praeruptorum.</p>

A total of 55 cases of advanced schistosomiasis patients combined with Ⅲ-grade hepatic fibrosis and ascites were randomized into a splenectomy group and non-splenectomy group. The peripheral vein blood phlebotomized from these patients were detected for leucocytes, hematids, thrombocytes, acidophils, glutamic-pyruvic transaminase,alkaline phosphatase,albumin, total bilirubin,three-type precollagen, fore-type collagen, hyaluronic acid, IgG, IgA, C_3, C_4 and the sub-group of lymphocytes such as CD3、CD4、 CD8 、CD56 + 16. There were no significant difference on hepatic function and the level of hepatic fibrosis between the groups above metioned. It could be found that leucocytes, thrombocytes, IgG, IgA, CD56 + 16 increased while CD3, CD4, and albumin decreased in the splenectomy group. In conclusion, leucocytes and thrombocytes increase after splenectomy, cytoimmunity declines and humoral immunity enhances.
