甲型H1N1流感病變型酶聯(lián)免疫法檢測(cè)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。

在系 統(tǒng)進(jìn)化中，腦皮可分成三個(gè)階段：古腦皮、原腦皮和新腦皮。在爬行 動(dòng)物中*出現(xiàn)，并在哺乳動(dòng)物中高度完善。新腦皮是由側(cè)腦室外壁 的神經(jīng)物質(zhì)生長(zhǎng)而成，并包圍著初生腦皮層（原腦皮），原腦皮的殘 余稱為海馬，在側(cè)腦室內(nèi)，仍為嗅覺(jué)中樞。大腦皮層由發(fā)達(dá)的新腦皮 層構(gòu)成，它接受來(lái)自全身的各種感覺(jué)器傳來(lái)的沖動(dòng)，通過(guò)分析綜合， 并根據(jù)已建立的神經(jīng)而產(chǎn)生相應(yīng)反映。人腦由大腦、小腦、間腦 、腦干組成。其中：大腦是中樞神經(jīng)系統(tǒng)的部分，也是腦的主要部分 。分為左右兩個(gè)大腦半球，二者由神經(jīng)纖維構(gòu)成的胼胝體相連。大腦 半球表面有許多彎彎曲曲的溝裂，稱為腦溝，其間凸出的部分稱為腦 回。這些腦溝、腦回就像一塊皺攏起來(lái)的綢布，一旦展平，它的面積 像半張普通報(bào)紙大小，約2250平方厘米。腦干（brainstem）上承大 腦半球，下連脊髓，呈不規(guī)則的柱狀形。經(jīng)由脊髓傳至腦的神經(jīng)沖動(dòng) ，呈交叉方式進(jìn)入：來(lái)自脊髓右邊的沖動(dòng)，先傳至腦干的左邊，然后 再送入大腦；來(lái)自脊髓左邊者，先送入腦干的右邊，再傳到大腦。腦 干的功能主要是維持個(gè)體生命，包括心跳、呼吸、消化、體溫、睡眠 等重要生理功能，均與腦干的功能有關(guān)。腦干部位又包括以下四個(gè)重 要構(gòu)造：1．延髓（medulla）延髓居于腦的zui下部，與脊髓相連；其 主要功能為控制呼吸、心跳、消化等。2．腦橋（pons）腦橋位于中腦 與延髓之間。腦橋的白質(zhì)神經(jīng)纖維，通到小腦皮質(zhì)，可將神經(jīng)沖動(dòng)自 小腦一半球傳至另一半球，使之發(fā)揮協(xié)調(diào)身體兩側(cè)肌肉活動(dòng)的功能。3 ．中腦（midbrain）中腦位于腦橋之上，恰好是整個(gè)腦的中點(diǎn)。中腦 是視覺(jué)與聽(tīng)覺(jué)的反射中樞，凡是瞳孔、眼球、肌肉等活動(dòng)，均受中腦 的控制。4．網(wǎng)狀系統(tǒng)（reticular system）網(wǎng)狀系統(tǒng)居于腦干的中 央，是由許多錯(cuò)綜復(fù)雜的神經(jīng)元集合而成的網(wǎng)狀結(jié)構(gòu)。網(wǎng)狀系統(tǒng)的主 要功能是控制覺(jué)醒、注意、睡眠等不同層次的意識(shí)狀態(tài)。
In the evolution of the system, the brain can be divided into three stages: ancient brain, the original brain and neocortex. First appeared in reptiles and highly refined in mammals. The new brain is formed by the growth of neural material in the lateral wall of the lateral ventricle and surrounds the nascent cortex (the original cerebral cortex). The remnants of the original brain, called the hippocampus, remain the olfactory center in the lateral ventricle. The cerebral cortex consists of a well-developed neocortex that receives impulses from various sensory organs throughout the body, analyzing the complex and responding to established neural connections. Human brain by the brain, cerebellum, diencephalon, brain stem composition. Among them: the brain is part of the central nervous system, but also the main part of the brain. Divided into two cerebral hemispheres, the two connected by the corpus callosum composed of nerve fibers. The surface of the cerebral hemispheres have many twists and turns of the crack, known as the sulci, during which the bulge is called the brain back. These sulci, brain back like a piece of silk up and down, once flattened, its area is like half the size of an ordinary newspaper, about 2250 square centimeters. Brainstem (brainstem) on the hemisphere, even under the spinal cord, was irregular columnar shape. From the spinal cord to the brain's nerve impulses, was crossed into: impulse from the right side of the spinal cord, the first spread to the left brain stem, and then into the brain; from the left spinal cord, the first sent to the right brain stem, and then spread to the brain . The main function of the brain stem is to maintain individual life, including heart, breath, digestion, body temperature, sleep and other important physiological functions, are related to the function of the brain stem. Brains include the following four important structures: 1. The medullla medulla occupies the lowermost part of the brain and connects with the spinal cord. Its main function is to control breathing, heartbeat, digestion and so on. 2. Pons The pons are located between the midbrain and medulla oblongata. Palar white matter nerve fibers, leading to the cerebellar cortex, the nerve impulse from the cerebellum hemispherical spread to the other hemisphere, so that it can play the role of coordination of muscle activity on both sides of the body. 3. Midbrain The midbrain, located above the pons, happens to be the midpoint of the entire brain. The brain is the visual and auditory reflex hub, all pupils, eyeballs, muscles and other activities, are subject to the control of the brain. 4. Reticular system The reticular system resides in the center of the brain stem and is a network of many intricate neurons. The main function of the mesh system is to control awakening, attention, sleep and other levels of consciousness.
