甲型流感病毒單檢試紙

流行性感冒（簡(jiǎn)稱流感）是流感病毒引起的急性呼吸道感染，也是一種傳染性強(qiáng)、傳播速度快的疾病。其主要通過(guò)空氣中的飛沫、人與人之間的接觸或與被污染物品的接觸傳播。典型的臨床癥狀是：急起高熱、全身疼痛、顯著乏力和輕度呼吸道癥狀。一般秋冬季節(jié)是其高發(fā)期，所引起的并發(fā)癥和死亡現(xiàn)象非常嚴(yán)重。該病是由流感病毒引起，可分為甲（A）、乙（B）、丙（C）三型，甲型病毒經(jīng)常發(fā)生抗原變異，傳染性大，傳播迅速，極易發(fā)生大范圍流行。甲型H1N1也就是甲型一種。本病具有自限性，但在嬰幼兒、老年人和存在心肺基礎(chǔ)疾病的患者容易并發(fā)肺炎等嚴(yán)重并發(fā)癥而導(dǎo)致的。

我司還提供其它進(jìn)口或國(guó)產(chǎn)試劑盒：登革熱、瘧疾、流感、A鏈球菌、合胞病毒、腮病毒、乙腦、寨卡、黃熱病、基孔肯雅熱、克錐蟲(chóng)病、違禁品濫用、肺炎球菌、軍團(tuán)菌、化妝品檢測(cè)、食品安全檢測(cè)等試劑盒以及日本生研細(xì)菌分型診斷血清、德國(guó)SiFin診斷血清、丹麥SSI診斷血清等產(chǎn)品。

膠原纖維粗細(xì)不等，直徑在1～20μm之間，有分支交織 成網(wǎng)。膠原纖維是由更細(xì)的膠原原纖維集合而成。膠原纖維的化學(xué)成 份是膠原蛋白。膠原纖維的靱性大，抗拉力強(qiáng)，但彈性差。網(wǎng)狀纖維與膠原纖維比較，網(wǎng)狀纖維十分纖細(xì)（直徑0.2～1μm），也 有分支，細(xì)菌E染色不能顯示，用浸銀法能染成黑色，故又稱嗜銀纖維 。其主要化學(xué)成份也是膠原蛋白。疏松結(jié)締組織中的網(wǎng)狀纖維少，它 主要分布于網(wǎng)狀結(jié)締組織以及結(jié)締組織與其它組織的交界處，如上皮 的基膜下，毛細(xì)血管周?chē)忍?。蛋白多糖?/span>proteoglycan）是由蛋白 質(zhì)與大量多糖結(jié)合成的大分子復(fù)合物，是基質(zhì)的主要成分。其中多糖 主要是透明質(zhì)酸（細(xì)菌yaluronic acid），其次是硫酸軟骨素A、C（ c細(xì)菌ondroitin sulfate A、C）、硫酸角質(zhì)素A、C（keratin  sulfate）硫酸乙酰肝素（細(xì)菌eparan sulfate）等。它們都是以含 有氨基已糖的雙糖為基本單位聚合成的長(zhǎng)鏈化合物，總稱為糖胺多糖 （glycosaminoglycan,GAG）。由于糖胺多糖分子存在大量陰離子， 故能結(jié)合大量水（結(jié)合水）。透明質(zhì)酸是一種曲折盤(pán)繞的長(zhǎng)鏈 大分子，拉直可達(dá)2.5μm，由它構(gòu)成 蛋白多糖復(fù)合物的主干，其它糖胺多糖則以蛋白質(zhì)為核心構(gòu)成蛋白多 糖亞單位，后者再通過(guò)連接蛋白結(jié)合在透明質(zhì)酸長(zhǎng)鏈分子上（圖3-15 ）。蛋白多糖復(fù)合物的立體構(gòu)型形成有許多微孔隙的分子篩，小于孔隙的 水和溶于水的營(yíng)養(yǎng)物、代謝產(chǎn)物、激素、氣體分子等可以通過(guò)，便于 血液與細(xì)胞之間進(jìn)行物質(zhì)交換。大于孔隙的大分子物質(zhì)，如細(xì)菌等不 能通過(guò)，使基質(zhì)成為限制細(xì)菌擴(kuò)散的防御屏障。溶血性鏈球菌和癌細(xì) 胞等能產(chǎn)生透明質(zhì)酸酶，破壞基質(zhì)的防御屏障，致使感染和腫瘤浸潤(rùn) 擴(kuò)散。糖蛋白（glycoprotein）是基質(zhì)內(nèi)另一類重要的生物大分子，與蛋白 多糖相反，其主要成分是蛋白質(zhì)。Collagen fibers ranging in thickness, the diameter of 1 ~ 20μm, with branches intertwined into a network. Collagen fiberVictoria is made up of finer collagen fibrils. The chemical composition of collagen fibers is collagen. Collagen fiber 靱 big, strong tensile strength, but poor flexibility. Reticular fibers and collagen fibers thanIn contrast, the reticular fibers are very slender (0.2 to 1 μm in diameter), with branches and bacterial E stainingCan not be displayed, soaked with silver method can be dyed black, it is also called silver fiber. Its main chemical compositionIt is also collagen. Loose connective tissue in the mesh fiber less, it is mainly distributed in the network junctionConnective organizations and connective tissue and other organizations at the junction, such as the epithelial basement membrane, capillaryAround the tube and so on. Proteoglycan is composed of a large number of proteins and polysaccharidesSynthetic macromolecular complexes, is the main component of the matrix. Among them, polysaccharide is mainly hyaluronic acid(Bacteria yaluronic acid), followed by chondroitin sulfate A, C (c bacteriaondroitin sulfate A, C), keratin sulfate C) Heparan sulfate (bacteria eparan sulfate) and so on. They all contain amino groupsSugar has been disaccharide sugar as the basic unit of polymerization into long-chain compounds, collectively known as glycosaminoglycans(Glycosaminoglycan, GAG). Due to the presence of a large number of anions in glycosaminoglycan molecules,It can combine a lot of water (combined with water). Hyaluronic acid is a tortuous long-chain macromolecules, Straightening up to 2.5μm, which constitutes the backbone of the proteoglycan complex, other glycosaminoglycansThe protein as the core structure of proteoglycan subunits, the latter by connexins in theHyaluronic acid long chain molecules (Figure 3-15). The proteoglycan complex is formed in a stereoconfigurationMany microporous molecular sieves, less than pore water and water-soluble nutrients, metabolites,Hormones, gas molecules, etc. can be passed, facilitating the exchange of matter between blood and cells. BigThe macromolecular substances in the pores, such as bacteria, can not pass, so that the matrix becomes a limiting bacterial proliferationDefensive barrier. Hemolytic streptococcus and cancer cells can produce hyaluronidase, destruction of the matrixThe defense barrier, resulting in the spread of infection and tumor infiltration. GlycoproteinIs another important type of biological macromolecules within the matrix, contrary to proteoglycans, the main component is
