文摘The silk fabrics were matching dyed with three natural edible pigments(red rice red,ginger yellow and gardenia blue).By investigating the dyeing rates and lifting properties of these pigments,it was observed that their compatibilities were excellent in the dyeing process:dye dosage 2.5%(omf),mordant alum dosage 2.0%(omf),dyeing temperature 80℃and dyeing time 40 min.The silk fabrics dyed with secondary colors exhibited vibrant and vivid color owing to the remarkable lightness and chroma of ginger yellow.However,gardenia blue exhibited multiple absorption peaks in the visible light range,resulting in significantly lower lightness and chroma for the silk fabrics dyed with tertiary colors,thus making it suitable only for matte-colored fabrics with low chroma levels.In addition,the silk fabrics dyed with these three pigments had a color fastness that exceeded grade 3 in resistance to perspiration,soap washing and light exposure,indicating acceptable wearing properties.The dyeing process described in this research exhibited a wide range of potential applications in matching dyeing of protein-based textiles with natural colorants.
文摘目的 探讨贮存时间对红细胞非典型趋化因子受体1(atypical chemokine receptor 1,ACKR1)的趋化因子清除功能及储存的影响。方法 6袋去白细胞悬浮红细胞制剂,每袋通过无菌热合机分出2小袋(10 mL/袋),置于血液贮存冰箱储存,分别于贮存d5、d25取出,进行红细胞CCL5、CXCL8以及CCL11含量以及ACKR1趋化因子清除功能测定。同时采集贮存期在d5~25的42份(1 mL/份)去白细胞悬浮红细胞制剂标本,进行红细胞膜上ACKR1表达及趋化因子CCL5、CXCL8以及CCL11含量的检测。结果 贮存期d 25和d 5相比,红细胞裂解液CCL5(pg/mL)(467.7±250.2 vs 586.9±209.5,P>0.05)及CCL11(pg/mL)(122.2±30.3 vs 125.5±32.7,P>0.05)浓度无差异,而CXCL8的浓度降低(pg/mL)(42.4±5.3 vs 24.3±5.9,P<0.05),红细胞ACKR1对趋化因子CCL5(pg/mL)(2 634.0±730.2 vs 453.8±257.4,P<0.05)、CXCL8(pg/mL)(1 117.0±236.6 vs 306.2±28.3,P<0.05)以及CCL11(pg/mL)的清除能力下降(1 278.0±164.5 vs 467.2±50.9,P<0.05)。在红细胞膜表面未检出趋化因子CCL5、CXCL8以及CCL11。红细胞表面ACKR1表达在d 5~25期间,无明显变化(P>0.05)。结论 红细胞内是贮存ACKR1结合趋化因子主要场所,在红细胞贮存期会发生红细胞ACKR1趋化因子清除功能的降低以及红细胞内部储存的某些ACKR1结合趋化因子的降低。
