| 1 | Effects and mechanisms of Bazhen decoction,Siwu decoction,and Sijunzi decoction on 5-fluorouracil-induced anemia in mice显示文摘OBJECTIVE:To investigate the effects of Bazhen decoction(BZD),Siwu decoction(SWD) and Sijunzi decoction(SJZD) in mice with anemia induced by5-fluorouracil(5-FU) and discussed the possible pharmacological hematopoietic mechanism to provide experimental evidence for the clinical use of the three classical prescriptions in the treatment of anemia.METHODS:Anemia was induced by intravenous injection of 5-FU and 80 female Kunming mice were randomly,assigned to oral administration of SWD,SJZD,or BZD daily for 10 days.Peripheral blood cells count and bone marrow cell cycle were monitored to evaluate anti-anemia effects.Serum cytokines,interferon-γ(IFN-γ),interleukin-3(IL-3),erythropoietin(EPO),granulocyte-macrophage colonystimulating factor(GM-CSF),and tumor necrosis factor-α(TNF-α) were assayed.EPO m RNA expression was assayed in kidney and liver tissue homogenates.RESULTS:BZD and SWD significantly increased the number of red blood cells,hemoglobin concentration,and hematocrit,promoted bone marrow cells to enter the cell cycle,proliferate and differentiate,significantly increased IL-3 secretion,and significantly inhibited IFN-γ secretion.BZD stimulated transcription of EPO m RNA in the kidney and liver and enhanced serum EPO expression.A therapeutic effect of SJZD was not observed.CONCLUSION:BZD and SWD treatment specifically enhanced hematopoietic function and mediated myelopoiesis by altering serum cytokines levels and accelerating entry of bone marrow cells into the cell cycle.Better curative effects were achieved via nourishing both Qi and blood(BZD) than by enriching the blood(SWD) or invigorating Qi(SWZD)alone. | Tian Yunan Xiang Yuke Wan Guoran Wan Dong Zhu Huifeng Wang Tao Yang Xian | 2016 | Journal of Traditional Chinese Medicine2016，36，4： | 12 |
| 2 | In vitro and in vivo evaluation of cubosomes containing 5-fluorouracil for liver targeting显示文摘The objective of this study was to prepare cubosomal nanoparticles containing a hydrophilic anticancer drug 5-fluorouracil(5-FU) for liver targeting. Cubosomal dispersions were prepared by disrupting a cubic gel phase of monoolein and water in the presence of Poloxamer 407 as a stabilizer.Cubosomes loaded with 5-FU were characterized in vitro and in vivo. In vitro, 5-FU-loaded cubosomes entrapped 31.21% drug and revealed nanometer-sized particles with a narrow particle size distribution. In vitro 5-FU release from cubosomes exhibited a phase of rapid release of about half of the entrapped drug during the first hour, followed by a relatively slower drug release as compared to 5-FU solution. In vivo biodistribution experiments indicated that the cubosomal formulation significantly(Po 0.05) increased5-FU liver concentration, a value approximately 5-fold greater than that observed with a 5-FU solution.However, serum serological results and histopathological findings revealed greater hepatocellular damage in rats treated with cubosomal formulation. These results demonstrate the successful development of cubosomal nanoparticles containing 5-FU for liver targeting. However, further studies are required to evaluate hepatotoxicity and in vivo antitumor activity of lower doses of 5-FU cubosomal formulation in treatment of liver cancer. | Mohamed Nasr Mohamed K.Ghorab Ahmed Abdelazem | 2015 | Acta Pharmaceutica Sinica B2015，5，1： | 9 |
