The purpose of this study was to determine radioprotective effects of troxerutin. Cell experiments were carried out to test the cytotoxicity of troxerutin on V79 cells and to observe effects on apoptosis caused by 60CO γ rays. A model of 8 Gy ray-caused damage of mice was established to observe the effect that troxerutin has on the physical symptom of irradiated mice and to calculate the 30-day survival rate. It showed that troxerutin had no obvious cytotoxicity at the level of less than 20 μg/ml; but had a redioprotective effect in dose-dependence on viability of V79 cells at the range of 0.2-5 μg/mL irradiated by 5 Gy ray of 60CO γ ray. After the 8 Gy irradiation, the mice lost some weight, were dried up in fur and feather, low spirit, awkward in movement, shrinking in body and handicapped in sight, while mice with troxerutin were much better. So it was clear that troxerutin could increase the 30-day survival rates of irradiated mice dramatically. These results collectively indicate that troxerutin is an effective radioprotective agent.  相似文献

 【摘要】 目的 探讨白细胞介素(IL)-10和IL-6在不同类型淋巴瘤组织与血浆中的表达及其意义。方法 收集97例淋巴瘤患者石蜡组织和血浆标本,应用免疫组织化学和酶联免疫吸附试验(ELISA)的方法观察组织与血浆中IL-10和IL-6表达情况。结果 IL-10和IL-6在不同类型淋巴瘤组织中皆呈阳性表达,且各亚型之间差异无统计学意义(χ2=0.815,χ2=0.542,均P>0.05);IL-10和IL-6分别在肿瘤中的巨噬细胞和血管内皮细胞也有不同程度的阳性表达。淋巴瘤患者血浆IL-10和IL-6水平[(232.57±191.59)pg/ml、(80.70±89.68)pg/ml]高于健康对照组[(59.12±68.35)pg/ml、(45.68±33.66)pg/ml],差异有统计学意义(t=6.968,t=2.896,P<0.05);血浆IL-10和IL-6水平随肿瘤细胞表达强度增强而增强(χ2=0.815,χ2=0.542,P<0.05);IL-10和IL-6在淋巴瘤细胞表达强度两者呈正相关(rs=0.394,P<0.05)。结论 IL-10和IL-6在淋巴瘤患者淋巴瘤组织和血浆中都有表达,淋巴瘤患者血浆IL-10和IL-6水平高于健康对照组,二者在淋巴瘤的发生、发展中起着一定的作用,可能作为淋巴瘤诊断的辅助指标。  相似文献

Purpose: The benefits of chemotherapy can be assessed in terms of tumour shrinkage, prolongation of life or simply palliation of symptoms. In the study reported here, in vitro correlates of these parameters were sought as a rational guide to the choice of newer agents in the clinic. Methods: The cytotoxicity and effects on IL-6 production of ten chemotherapy agents representing four different classes of drugs were tested against a panel of five mesothelioma cell lines. Results: The mesothelioma cells were more sensitive to the action of irinotecan (and its active metabolite SN38) and gemcitabine than the control cell lines. Gemcitabine and to a lesser extent irinotecan inhibited the secretion of the proinflammatory cytokine IL-6 at concentrations of each drug that produced only small decreases in cell viability. This effect was not seen in cells treated with docetaxel or vindesine. Higher doses of gemcitabine and irinotecan caused a surge in IL-6 release and this was not due to release of intracellular stores of IL-6 through lysis of the cells. Conclusions: These results suggest that irinotecan and gemcitabine are not only more likely to be active against mesothelioma than other new chemotherapy agents but may also produce a palliative effect in nonresponders to these agents by decreasing the secretion of IL-6.

PDT has been reported to induce cancer cell expression of cytokines, such as IL-6 and TNF-alpha, but it has been unclear whether cytokine expression by cancer cells is directly related to the antitumor effect of PDT. We treated Lewis lung carcinoma (LLC) cells with a new photosensitizer, mono-L-aspartyl chlorin e6 (NPe6) and light from a diode laser and found that expression of the mRNA of IL-2, IL-6, and TNF-alpha was increased by NPe6-mediated-PDT 6 hr later. To elucidate the mechanism of the direct anti-tumor effect of cytokine expression, we examined the photosensitivity of cytokine-gene-transfected cells, namely LLC-IL-2, LLC-IL-6, and LLC-TNF-alpha cells, by MTT assay. The IL-6 gene transfected, LLC-IL-6 cells were significantly more sensitive to cytotoxic effects than the parent LLC cells and other cytokine gene-transfected cells. This finding indicates that IL-6 expression modulates cellular sensitivity to PDT and that IL-2 and TNF-alpha expressions does not. In addition, the apoptosis of LLC-IL-6 cells induced by NPe6-PDT was greater than in the other cells as determined by DNA fragmentation and staining of apoptotic nuclei. Because IL-6 has been reported to induce apoptosis by downregulating expression of Bcl-2, we analyzed the expression of apoptosis-related Bcl-2, Bax, and cytochrome C by Western blot analysis. Decreased expression of Bcl-2 and cytochrome C was observed in both LLC cells and LLC-IL-6 cells. Bax protein increased in a time-dependent manner, and the ratio of Bax to Bcl-2 rose markedly after PDT in LLC-IL-6 cells. These results suggest that the increased sensitivity of LLC-IL-6 cells to PDT-induced cytotoxicity results from the high ratio of Bax to Bcl-2 in the IL-6-dependent apoptotic pathway. In conclusion, IL-6 expression plays a role in cellular sensitivity to PDT, and combination of IL-6 and PDT may provide a new strategy for cancer treatment.  相似文献
