美國(guó)OSOM流感病毒快檢試劑盒

流行性感冒（簡(jiǎn)稱(chēng)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。

復(fù)紅（alde細(xì)菌yde-fuc細(xì)菌sin）或地衣紅 （orcein）能將彈性纖維染成紫色或棕褐色。彈性纖維較細(xì)，直行, 分支交織，粗細(xì)不等（0.2－1.0μm）,表面光滑，斷端常卷曲（圖3 －2）。電鏡下，彈性纖維的核心部分電子密度低，由均質(zhì)的彈性蛋白 （elastin）組成，核心外周覆蓋微原纖維（microfibril），直徑約 10nm。彈性蛋白分子能任意卷曲，分子間藉共價(jià)鍵交聯(lián)成網(wǎng)。在外力 牽拉下，卷曲的彈性蛋白分子伸展拉長(zhǎng)；除去外力后，彈性蛋白分子 又回復(fù)為卷曲狀態(tài)（圖3－14）。彈性纖維富于彈性而韌性差，與膠原纖維交織在一起，使疏松結(jié)締組 織既有彈性又有韌性，有利于器官和組織保持形態(tài)位置的相對(duì)恒定， 又具有一定的可變性。網(wǎng)狀纖維網(wǎng)狀纖維（reticular fiber）較細(xì)，分支多，交織成網(wǎng)。網(wǎng)狀纖維 由Ⅲ型膠原蛋白構(gòu)成，也具有64nm周期性橫紋。纖維表面被覆蛋白多 糖和糖蛋白，故PAS反應(yīng)陽(yáng)性，并具嗜銀性。用銀染法，網(wǎng)狀纖維呈黑 色，故又稱(chēng)嗜銀纖維（argyrop細(xì)菌il fiber）。網(wǎng)狀纖維多分布在 結(jié)締組織與其它組織交界處，如基膜的網(wǎng)板、腎小管周?chē)⒚?xì)血管 周?chē)Ｔ谠煅鞴俸蛢?nèi)分泌腺，有較多的網(wǎng)狀纖維，構(gòu)成它們的支架 。可分為：疏松結(jié)締組織、致密結(jié)締組織、脂肪組織、網(wǎng)狀結(jié)締組織 、軟骨、骨和血液。疏松結(jié)締組織 廣泛存在于各器官之間、組織之間、甚至細(xì)胞之間。其 結(jié)構(gòu)特點(diǎn)是基質(zhì)多，纖維少，結(jié)構(gòu)疏松，呈蜂窩狀，故又稱(chēng)蜂窩組織 。該組織有連接、支持、防御、傳遞營(yíng)養(yǎng)和代謝產(chǎn)物等多種功能。（1）細(xì)胞：疏松結(jié)締組織中的細(xì)胞種類(lèi)較多，散在分布。其中有些是 經(jīng)常存在的較恒定的細(xì)胞，如成纖維細(xì)胞、脂肪細(xì)胞和未分化的間充 質(zhì)細(xì)胞。
Fu red (alde bacteria yde-fuc bacteria sin) or licorice red (orcein) can be elastic fibers stained purple or brown. Fibers thinner, straight, branched intertwined, ranging in thickness (0.2-1.0μm), the surface smooth, often curly end of the fracture (Figure 3 -2). Under electron microscopy, the central portion of the elastic fiber has a low electron density and is composed of a homogenous elastin. The outer periphery of the fiber is covered with microfibril with a diameter of about 10 nm. Elastin molecules can be any curly, intermolecular cross-linked by covalent network. Under the external force, the crimped elastin molecules stretch and elongate. After removing the external force, the elastin molecules return to the crimped state (Figure 3-14). Elastic fibers are rich in elasticity and poor in toughness. They are intertwined with the collagen fibers to make the loose connective tissue both elastic and tough, which helps the organs and tissues to maintain relatively constant morphological positions and has certain variability. Reticular fiber mesh (reticular fiber) thinner, more branches, woven into a network. The reticular fibers are composed of type III collagen and also have periodic stripes of 64 nm. The fiber surface is coated with proteoglycans and glycoproteins, so the PAS reaction is positive and has an argyrophilic property. Silver staining, reticular fibers were black, it is also known as silver silver fiber (argyrop bacteria il fiber). Reticular fibers are distributed in the junction of connective tissue and other tissues, such as the basement membrane of the membrane, around the tubules, around the capillaries. In hematopoietic organs and endocrine glands, there are more reticular fibers that make up their scaffolds. Can be divided into: loose connective tissue, dense connective tissue, adipose tissue, reticular connective tissue, cartilage, bone and blood. Loose connective tissue widely exists in various organs, between tissues, and even between cells. Its structural features are more matrix, less fiber, loose structure, was honeycomb, it is also known as honeycomb. The organization has many functions of connection, support, defense, delivery of nutrients and metabolites. (1) cells: loose connective tissue cells in more types, scattered distribution. Some of these are more often constant cells such as fibroblasts, adipocytes, and undifferentiated mesenchymal cells.
