This case report describes a 4-year-old girl with food aversion who received three separate courses of cefdinir mixed with PediaSure®, an iron-fortified nutritional formula. The patient's stool turned red with variable onset during all three courses of treatment. Moreover, the PediaSure® formula turned purple after mixed with cefdinir, an interaction that has not been previously reported. We recommend that medication counseling for pediatric patients taking cefdinir include a mention of these possible discolorations. 相似文献

目的根据基因编码序列推测其氨基酸序列,预测LRP16基因编码蛋白的功能并通过实验加以证实。方法利用GeneBank数据库获取LRP16基因序列,然后推测出该基因编码蛋白质的一级结构,对该序列蛋白结构域的同源性进行搜索;将LRP16基因ORF插入pcDNA3.1,构建LRP16基因的真核表达质粒,采用Superfect稳定转染急性粒细胞白血病细胞系HL-60,筛选稳定表达LRP16基因的细胞;以紫外灯照射筛选后有HL-60稳定过表达的HL-60细胞和对照细胞;采用单细胞凝胶电泳技术检测有LRPl6过表达对HL-60细胞增殖及DNA损伤后修复的影响。结果在LRPl6基因理论蛋白序列的第148至315氨基酸残基之间具有与人类组蛋白H2A1C末端相类似的同源序列hismacro、COG2110和A1PP,同源性高达80%以上。LRP16基因的过表达具有抗紫外线引起HL-60细胞DNA损伤和增强损伤后的修复作用。结论LRP16基因编码蛋白可能具有抗紫外线的DNA损伤作用。 相似文献

Summary Foreskin fibroblasts cultured in a medium containing protoporphyrin and exposed to violet light lose the capacity to proliferate. This phenomenon can be assessed on the basis of the ability of the irradiated cells to form colonies. Potentially lethal injuries can, however, be repaired during post-irradiation incubation under optimal growth conditions. We investigated the photodynamically induced transformations of certain molecular targets in the irradiated cells. Biochemical analysis showed that only traces of unsaturated fatty acids were oxidized, but SH groups of both the membranes and the cytosol appeared to be very sensitive targets. Of the tryptophan content, 20% was damaged during irradiation. Recovery was observed during post-irradiation incubation. The tryptophan content and the SH groups recovered to some extent, and these results showed a good correlation with the regeneration of surviving cells. 相似文献

Reactive dyes are used especially for colouring natural fibres (cotton, silk and wool) that arc widely used in Western countries, particularly Italy, in the production of clothes. The aim of our study was to investigate sensitization to the most commonly used reactive textile dyes in patients undergoing patch tests, and to assess the clinical relevance of contact sensitization of these dyes. 1813 consecutive patients underwent patch tests with the GIRDCA standard series and an additional textile series of 12 reactive dyes. 18 of these patients were sensitized to reactive dyes (0.99) (4 only to reactive dyes). The dyes most frequently responsible for positive patch tests were Red Cibacron CR and Violet Remazol 5R (respectively, 8 and 5 positivities). In 5 cases only was a history of intolerance to particular garments given; of 4 patch tests performed with pieces of garment, 2 were positive. In 1 occupationally-exposed patient, airborne contact dermatitis was suspected. Owing to the lack of up-to-date patch test series, some cases of allergic contact dermatitis from textile dyes are probably misdiagnosed: new colouring agents are continuously introduced to the market, so that a close relationship with textile industry is necessary to improve our diagnostic tools. 相似文献
