【包装规格】
1人份/袋,40人份/盒
【预期用途】
尼古丁(Nicotine)是烟草中的主要生物碱,是导致吸烟成瘾的物质动因,也是评价人体摄入烟草烟雾的常用指标。但因为尼古丁半衰期短,无法作为标志物检测,其代谢物可替宁因为半衰期长作为吸烟和戒烟的标志物。
本品采用竞争抑制法和胶体金免疫层析技术,用于快速定性检测人体唾液中的可替宁,适用于评价烟草烟雾摄入的初步筛查。
【主要组成成份】
【检验方法】
本品采用竞争抑制法和胶体金免疫层析技术,用于定性检测人体唾液中的代谢物苯甲酰爱康宁,适用于药物滥用的初步筛查。
【检验结果的解释】
阳性(+):仅在控制区(C)出现一条紫红色条带,在检测区(T)无紫红色条带出现。阳性结果表明:唾液中的可替宁浓度在阈值(50ng/mL)以上。
阴性(-):出现两条紫红色条带。一条位于检测区(T),另一条位于控制区(C)。阴性结果表明:唾液中的可替宁浓度在阈值(50ng/mL)以下。
无效:控制区(C)未出现紫红色条带。表明操作不当或试剂盒已失效。在此情况下,应再次仔细阅读说明书,并用新的试剂盒重新测试。如果问题仍然存在,应立即停止使用此批号产品,并与当地供应商。
注意:检测区(T)紫红色条带可呈现颜色深浅的现象。但是,在规定的观察时间内,不论该色带颜色深浅,即使只有非常弱的色带也应判定为阴性结果。

反之,如果细菌表面菌群中有益菌占主导地位,那么抗细菌细菌物的效果会显著细菌于细菌表面菌群中害菌占主导的个体。产甲烷菌(Methanogen)是一类特殊的生理菌,是自然界碳素物质循环中厌氧生物链的zui后一个成员,是一类能够将无机或有机化合物发酵成甲烷和二氧化碳的古细菌。
产甲烷菌这一名词是由Bryant提出的,其目的是为了与另一类需氧甲烷氧化菌(Aerobic methane-oxidizing bacteria)相区别。产甲烷菌属古细菌域宽广古生菌界(Kingdom Euryarchaeota),是一种特殊的专门的生理群,具有特殊的细胞成分和代谢方式,是一群形态多样,可代谢H2、CO2及少数几种简单有机物,生成CH4的严格厌氧的古细菌。
产甲烷菌可将无机或有机化合物厌氧发酵转化成甲烷和二氧化碳,广泛分布于自然界中,在水田、沼泽、淡水和海洋的沉积物、人和动物的肠道以及瘤胃等厌氧环境中都有产甲烷菌的存在。它们可生活在各种自然环境下,甚至在一些环境或细菌温环境下。无论是细菌温产甲烷菌还是细菌温产甲烷菌,它们突出的特点是产生甲烷,并在严格的厌氧条件下生活。产甲烷菌在废弃物厌氧消化、细菌浓度有机废水处理、沼气发酵及反刍动物瘤胃中食物消化等过程中均起着关键性作用,同时产甲烷菌所释放出来的甲烷也是导致温室效应的重要因素,甲烷的排放量每年大约为500-600tg,其中74%是由产甲烷菌的代谢产生的(参考文献:Lowe DC. Global change: a green source of surprise. Nature, 2006,439(7073)148-149.)。同时,产甲烷菌在有机质的厌氧生物处理工业应用中也发挥着关键性的作用,如开发煤层气资源、沼气的发酵等,产甲烷菌也是环境微生物的研究焦点。肠道菌群及其活动对宿主有很大的影响,主要有以下作用:
一、生物屏障作用:正细菌菌群在肠道中构成机体重要的生物屏障,维护肠道生态的稳定,抵御外来的有害细菌。主要通过占位性保护、营养竞争、产生抗菌物质等机制发挥屏障功能。肠道细菌和肠道黏膜上皮细胞紧密结合,形成一层膜菌群,阻碍致细菌菌和肠黏膜的接触,起到了占位性的保护作用。

Conversely, if beneficial bacteria are dominant in the bacterial surface flora, then the effect of the antibacterial bacteria will be significant for the bacteria that are predominantly bacterial in the bacterial surface flora. Methanogen, a special class of physiological bacteria, is the last member of the anaerobic biochain chain in the circulation of the carbonaceous material in nature. It is a class of archaea that ferment inorganic or organic compounds to methane and carbon dioxide.
The term methanogen is proposed by Bryant for the purpose of distinguishing it from another class of Aerobic methane-oxidizing bacteria. Methanosporium Archaebacteria Broad-spectrum Archaea (Kingdom Euryarchaeota), is a special specialized physiological group, with special cellular components and metabolic methods, is a group of diverse forms, can metabolize H2, CO2 and a few Simple organics to produce strictly anaerobic archaebacteria of CH4.
Methanogens convert anaerobic fermentation of inorganic or organic compounds into methane and carbon dioxide and are widely distributed in nature. They are found in paddy fields, swamps, freshwater and marine sediments, human and animal intestines, and rumen and other anaerobic environments Methanogenic bacteria exist. They can live in a variety of natural environments, even in some extreme environments or bacterial temperatures. Whether it is bacterial methanogenic bacteria or bacterial methanogenic bacteria, their prominent feature is the production of methane, and live under strict anaerobic conditions. Methanogenic bacteria play a key role in the process of anaerobic digestion of waste, organic wastewater treatment of bacterial concentration, biogas fermentation and food digestion in the rumen of ruminants, and the methane released from methanogenic bacteria is also important for causing the greenhouse effect As a result, global methane emissions are estimated at about 500-600 tg per year, of which 74% is due to methanogenesis (Reference: Lowe DC. Global change: a green source of surprise. Nature, 2006, 439 (7073) 148-149.). At the same time, methanogenic bacteria also play a key role in the industrial application of anaerobic biological treatment of organic matter, such as the development of coalbed methane resources and the fermentation of biogas. Methanogenic bacteria is also the focus of research on environmental microorganisms. Intestinal flora and its activities have a great impact on the host, the main role of the following:
First, the role of biological barriers: Positive bacterial flora in the intestine constitutes an important biological barrier to maintain the stability of intestinal ecology, to resist the harmful foreign bacteria. Mainly through the occupying protection, nutritional competition, antibacterial substances and other mechanisms to play a barrier function. Intestinal bacteria and intestinal mucosal epithelial cells in close contact with the formation of a layer of membrane flora, hinder the bacteria caused by contact with intestinal mucosa, play a protective role of space.
