Methods: Seventy-five Sprague-Dawley rats were divided into 5 groups by a random number table, including control, positive, model, low-dose(LD) and high-dose(HD) ESP groups, 15 rats in each group. All the rats, except those in the control group, were developed PSYD induced-diarrhea based on its pathology and etiology. The rats in positive, LD and HD ESP groups were treated with Shenling Baizhu Pill(参苓白术丸), LD(1.05 g/kg) or HD(3.50 g/kg) ESP petroleum ether extract once a day for 2 weeks, respectively. Body weight change and diarrhea index were measured. The histology scores of the kidney were evaluated via hematoxylin and eosin(HE) staining. Aquaporin-3(AQP3) expression in the colon was analyzed by immunofluorescence, quantitative reverse transcription-polymerase chain reaction(qRT-PCR) and Western blot, respectively. Results: Compared with the model group, oral administration of LD and HD ESP prevented body weight loss and inhibited diarrhea after 2-week treatment(P<0.05). Kidney deterioration was impeded, and the histology score in LD and HD ESP groups were 8.2 and 10.5, respectively, which were both higher than those in the model group(P<0.05). In addition, ESP treatment alleviated rat colitis, and HD ESP significantly improved the AQP3 positive staining intensity in the colon tissue compared with the model group. The result from Western blot revealed that AQP3 protein synthesis in colon tissue of LD and HD ESP groups increased by 2.1-and 5.9-fold compared with the model group(P<0.05). qR T-PCR result showed that AQP3 gene expression in the HD ESP group was also up-regulated by 2.5-fold normalized to the model group(P<0.05). Conclusion: ESP extract effectively alleviates the symptoms of PSYD and relieves PSYD-induced diarrhea by improving AQP3 synthesis in the colon.展开更多
目的 GC-MS分析二神丸中补骨脂和肉豆蔻的炮制对其4种组合挥发性成分的影响.方法 采用水蒸气蒸馏法提取挥发油,气相色谱条件为毛细管色谱柱（HP-5 mS 5％ Phenyl methyl siloxane,30 mm ×0.25 mm ×0.25 μm）,进样口温度为250...目的 GC-MS分析二神丸中补骨脂和肉豆蔻的炮制对其4种组合挥发性成分的影响.方法 采用水蒸气蒸馏法提取挥发油,气相色谱条件为毛细管色谱柱（HP-5 mS 5％ Phenyl methyl siloxane,30 mm ×0.25 mm ×0.25 μm）,进样口温度为250℃,程序升温,载气为氦气;质谱条件为电子轰击电离（能量为70 eV）,四级杆温度为150℃,离子源温度为230℃.结果 4种组合分别检测出77、109、89和70种化合物,鉴定出了其中78种化合物的结构,占其挥发油总量的97.20％～98.87％.结论 组合Ⅳ（盐补骨脂＋煨肉豆蔻）中补骨脂酚和黄樟醚的量最低,挥发性成分的总量减少,说明补骨脂和肉豆蔻炮制后入药可降低毒性.展开更多
