In order to preserve the nutrients in shallots, after harvest, various protocols, including incubation, drying or lyophilization of the shallot are developed in this study. Using aqueous extracts of ground shallot powders, this study examines the antioxidative properties of shallots on the formation of hydroxyl radical species (.OH) generated via a Fenton-type reaction. A ribose degradation assay shows that all aqueous extracts of shallot prepared in this study exhibit enhanced levels of .OH, suggesting that processed shallot, like strong reductants such as ascorbate, has a strong reducing power, which converts FeIII to FeII in a Fenton’s reaction and increases the levels of .OH. A DNA integrity assay shows that fragmentation of super-coiled plasmid DNA, pGEM-7Zf(-), by .OH is diminished in the presence of all shallot aqueous extracts, albeit to various extents. Finally, electron paramagnetic resonance (EPR) experiments show that lyophilized shallot completely scavenges .OH, as evidenced by the disappearance of the EPR-active reaction product generated between spin trap, 5,5-dimethyl-1-pyrroline-N-oxide (DMPO), and ?OH. The results of this study show the potential of a daily intake of preserved shallot to boost antioxidative protection against the toxicity of ?OH or any other damaging radicals.

目的探讨妥布霉素注射液雾化吸入对呼吸道纤毛的毒性影响。方法以人鼻黏膜纤毛和牛蛙上颚黏膜纤毛为研究对象,实验分为空白对照组(0.9%NaCl)、阳性对照组(1%去氧胆酸钠)、注射液实验组(硫酸妥布霉素注射液)和吸入溶液实验组(妥布霉素吸入溶液)。比较给药前后纤毛持续运动时间(PVD)和纤毛持续运动时间百分比(PPV),评价各组纤毛毒性差异。采用牛蛙上颚黏膜纤毛进一步研究妥布霉素注射液中所含辅料[苯酚、亚硫酸氢钠和乙二胺四乙酸二钠(EDTA-2Na)]的纤毛毒性。结果人鼻黏膜纤毛实验空白对照组、阳性对照组、注射液实验组和吸入溶液实验组的PVD分别为(472.33±37.56)、0、(8.00±1.10)和(112.00±36.55)min;PPV分别为100%、0、(1.69±0.23)%和(23.71±7.74)%。注射液实验组与空白对照组、吸入溶液实验组比较,差异均有统计学意义(均P<0.05)。牛蛙上颚黏膜纤毛实验空白对照组、阳性对照组、注射液实验组和吸入溶液实验组的PVD分别为(614.67±23.30)、(51.67±10.60)、(311.50±62.03)和(430.17±40.32)min;PPV分别为100%、(8.41±1.72)%、(50.68±10.09)%和(69.98±6.56)%。注射液实验组与空白对照组、吸入溶液实验组比较,差异均有统计学意义(均P<0.05)。牛蛙上颚黏膜纤毛实验空白对照组、苯酚组、亚硫酸氢钠组和EDTA-2Na组的PVD分别为(614.67±23.30)、(140.67±24.62)、(417.83±74.62)和(601.17±27.07)min;PPV分别为100%、(22.89±4.01)%、(67.98±12.14)%和(97.80±4.40)%。苯酚组与空白对照组、亚硫酸氢钠组比较,亚硫酸氢钠组与空白对照组比较,差异均有统计学意义(均P<0.05)。结论相比吸入溶液,抗生素注射剂存在较高的纤毛毒性,系由于其处方中防腐剂苯酚、抗氧剂亚硫酸氢钠具有不同程度的纤毛毒性。雾化吸入使用时需谨慎评估其风险获益。
