本文采用新型无机絮凝剂FOLY A-F联合木炭柱处理针织厂印染废水取得较为满意的效果。废水CODCr含量的波动范围为161.8~483.6ppm;固体悬浮物95.5~442ppm;pH8.4~11.6。经本方法处理后,溶液基本上无色透明,固体悬浮物近于0,CODCr含量少于100ppm,CODCr去除率为77.9%。以上四项检测指标均达到国家规定的排放标准。适用于处理中、小型针织厂的废水。 相似文献

Toll样受体2胞外域及其氨基端和羧基端片段的克隆与序列分析 总被引:1,自引:1,他引:0
目的:为研究TLR2胞外域在肽聚糖诱导的信号转导中的功能,构建TLR2胞外域及其氨基端和羧基端片段真核表达载体。方法:提取HL-60细胞总RNA,以RT-PCR方法获取了TLR2胞外域cDNA片段,将其与pGEM-T Easy载体连接,转化E.coli JM109,建立了TLR2胞外域的cDNA克隆;籍此,又相继克隆了胞外域的氨基端和羧基端片段,然后将这三个片段克隆到真核表达载体pcDNA3中。结果:序列分析表明,与GenBank中的人TLR2全长cDNA序列比较,仅4个碱基不同,同源性为0.998。结论:成功获得了HL-60细胞TLR2胞外域及其氨基端和羧基端片段的克隆。 相似文献

Objective To assess the relation between perineal inspection and sphincter integrity in parous women.
Design Prospective observational study.
Setting District general hospital.
Population Fifty-seven consecutive parous women attending a gynaecology clinic for problems unrelated to the pelvic floor.
Methods A detailed history of bowel function and mode of delivery obtained; the perineum inspected to determine the presence and position of scarring, and anal endosonography performed.
Results In 19 women with an intact perineum on inspection, endosonography showed perineal scarring in five, with both perineal and sphincter scarring in three. Four had urge faecal incontinence. Three patients had a perineal tear only on inspection, but this group was too small for analysis and was discounted. Nine had an episiotomy scar only. Endosonography demonstrated perineal scarring in four, and combined perineal and sphincter scarring in two; one woman in this group had urge faecal incontinence. Twenty-six women had episiotomy and perineal tears on inspection. Endosonography revealed underlying perineal scarring in five women, with combined perineal and sphincter scarring in 14; six women in this group had urge faecal incontinence and one passive incontinence for flatus. Sonographically the scarring was anterior and circumferential rather than radial, and mostly left-sided, whereas on inspection episiotomy and perineal scarring were right sided.
Conclusions A normal perineum on clinical examination does not exclude underlying sphincter damage. The incidence of sphincter damage increases significantly when an episiotomy scar is associated with a perineal tear. 相似文献

血清TPS浓度在消化道肿瘤中价值的研究 总被引:4,自引:0,他引:4
共选择30例消化道肿瘤病人,其中食管癌,胃癌,大肠癌各10例,设健康献血者30例,对两组血清特异型组织多肽抗原浓度进行了检测,结果肿瘤组血清TPS浓度明显高于健康人。消化道肿瘤阳性检出经达70%,其中食管癌80%,胃癌60%,大肠癌70%。消化道肿瘤合并淋巴转移阳性检出率达76.9%,其中食管癌100%,胃癌66.7%,大肠癌70.0%。随着病程发展,血清TPS浓度呈现升高趋势。 相似文献

Childhood sarcoidosis is a rare disorder with protean manifestations. The case of a child with prolonged fever, hepatosplenomegaly, pancytopenia, and systemic necrotizing vasculitis manifesting as fever, rash and skin infarctions, digital pregangrene, and foot drop is reported. This is the first case of systemic necrotizing vasculitis reported in sarcoidosis. The fulminant course of the disease required treatment with intravenous pulsed cyclophosphamide and high doses of corticosteroids. The spectrum of vasculitis in childhood and adult sarcoidosis is reviewed. 相似文献

作者采用四甲基谷氮唑盐(MTT)实验检测全反式维甲酸(ATRA)对人胰腺癌细胞系JF-305细胞的生长抑制作用;通过细胞病理学和电镜观察经ATRA作用后人胰腺癌细胞形态、超微结构的改变。结果提示:ATRA能够明显地抑制人胰腺癌细胞生长(P<0.05),随药物浓度增加而抑制作用增强,最大抑制率达34.7%。经ATRA处理后增殖细胞明显减少(P<0.01),细胞内代谢减慢,细胞的分泌功能恢复,细胞恶性程度降低。作者认为:ATRA可抑制人胰腺癌细胞系JF-305细胞的生长并诱导其成熟分化。 相似文献
