軍團菌尿抗原檢測試劑(膠體金法)
廣州健侖生物科技有限公司
產品名稱:膠體金檢測法
連接著膜的是包含有干燥金標的金標墊(通常是玻璃 纖維)。對于目前大多數可做的檢測項目,這種結合墊含有吸附了針對待檢分析品的特異性抗體或抗原的金粒子。樣品墊通常為紙質,附著著結合墊。當使用樣品墊時,液體樣品通過毛 細擴散作用穿移過結合墊,再水化金交聯物,使待分析樣品與交聯物相互作用。然后金交聯物與待分析樣品復合物轉移至膜條帶上再移向蛋白結合物,復合物在此處被固定后以一條細細的紅線的形式產生明顯的信號。第二條線是控制線,由余下的金交聯物形成于膜上,表明測試完成。
顧名思義,快速檢測應在短時間內提供結果,準確的說是在幾分鐘內。這種檢測法必須方便、精確、可靠、廉價、是一次性的而且操作簡易的。它們也必須容易和清楚的說明書,甚至是沒有經驗的使用者也能操作。從生產廠家的觀點來看,這種快速檢測將會帶來巨大的附加值,且容易向世界各地的使用者推廣,而無論使用者其有無此項檢測的經驗。
Connected to the film is a Gold standard pad containing gold (usually glass fiber). For most of the currently available assays, this binding pad contains gold particles that have been adsorbed to a specific antibody or antigen for the analyte to be tested. The sample pad is usually paper, with bond pads attached. When a sample pad is used, the liquid sample moves through the bond pad by capillary diffusion and rehydrates the gold crosslink so that the sample to be analyzed interacts with the crosslinker. The complex of the gold cross-linker and the sample to be analyzed is then transferred to the membrane strip and to the protein conjugate where the complex is fixed to produce a clear signal in the form of a thin red line. The second line is the control line formed by the remaining gold cross-links on the membrane, indicating that the test is completed.
As the name suggests, rapid testing should provide results in a short period of time, to be precise, in minutes. This test method must be convenient, accurate, reliable, cheap, is one-time and easy to operate. They must also be easy and clear, even by inexperienced users. From the point of view of the manufacturer, this rapid test will bring tremendous added value and will be easily marketed to users all over the world, regardless of whether or not the user has experience with this test

簡介:軍團桿菌,系需氧革蘭氏陰性桿菌,以嗜肺軍團菌zui易致病。現已提出了超過30種軍團桿菌,至少19種是人類肺炎的病原。其中zui常見病原體為嗜肺軍團菌(占病例的85%~90%),其次是L.micdadei(占5%~10%),再次是L.bozemanii和L.dumoffii.此類細菌形態相似,具有共同的生化特征,引起類似疾病。

1.肺炎型
潛伏期一般為2~10天,前驅癥狀為乏力、頭痛、全身肌肉酸痛,于1~2天內突然發熱,可達40℃以上,多呈稽留熱。病程早期即可出現多系統受累癥狀。絕大多數患者有咳嗽,起初為干咳,半數患者轉成非膿性黏稠痰或略帶膿性痰,痰中常含少量血絲,個別可咯血。
少數患者有胸痛,呼吸困難較為多見。肺部可聞及細濕啰音。繼之可出現明顯肺實變體征。約25%有、嘔吐及腹瀉等消化道癥狀,有的腹瀉為惟一*癥狀。神經癥狀多見于急性期,包括不同程度意識障礙、肌張力增強或陣顫、步態不穩等,可有暫時性肢體軟癱,無神經系統定位體征。多數病例體溫于8~10天下降,肺炎等全身癥狀隨之好轉。但重癥病例可發生心、肝、腎功能損害,甚至功能衰竭致死,亦可遷延并發肺膿腫等。
2.非肺炎型(龐蒂亞克熱)
此型為該病菌感染的輕型,潛伏期為5~66小時,半數為36小時左右。發冷、發熱起病,體溫一般不超過39.5℃,伴頭痛、肌痛等。呼吸道癥狀不嚴重,半數患者僅輕度干咳及胸痛,部分咽喉干痛。個別可有腹瀉、清水樣便或者失眠、眩暈、記憶力減退、意識蒙眬、頸強直、震顫等神經系統表現,均較輕。非肺炎型的病程3~5天自愈。

Including brain tumors, brain abscesses, intracranial hematomas, cysts (arachnoiditis), brain parasites and so on. on the one hand
, The tumor itself on the intracranial pain-sensitive tissue oppression, change, can cause local and adjacent sites
Headache (traction bacterial headache), such as pituitary tumor can produce double temporal or retrobulbar pain, headache was carried out
Bacteria aggravating, and have the limitations of the nervous system; the other hand, 80% of patients with intracranial pressure increased tumor
High, the whole head showed pain, burst pain, early onset occurred only in the early morning (due to supine
After a night of cerebral venous blood, increased intracranial pressure), and gradually for the continued bacterial pain, cough
, Due to sudden increase in intracranial pressure, headache aggravated, and vomiting, depending on bacterial edema, retinal hemorrhage,
Psychiatric symptoms, epilepsy and so on.
Low intracranial pressure syndrome
Occurred in lumbar puncture, craniocerebral injury, surgery or meningoencephalitis, etc. and severe dehydration, etc.
Under the circumstances, the lateral position of the cerebrospinal fluid pressure in the 0.59-0.78kPa (70-80mm water column) below, or
Can not flow out Sudden onset of severe headache, often accompanied by bacteria, vomiting, Department of intracranial pressure
Further decline, intracranial pain-sensitive tissue loss of support of cerebrospinal fluid by traction caused by, so
Also belong to traction bacteria headache. After supine headache quickly relieve. Even or with Xu pulse and blood pressure.
Epilepsy bacteria headache
More common in adolescents and children, headache was severe beating bacterial or blast pain, attack and termination are more
Suddenly, for a few seconds to tens of minutes, even for up to one day, attack frequency range. May be accompanied by bacteria
, Vomiting, dizziness, runny nose, tearing, abdominal pain, disturbance of consciousness or bacteria. EEG examination
Especially in the attack into the usual epilepsy waveform, but also have other types of epileptic seizures, family history of epilepsy
And the history of the etiology, taking antiepileptic drugs can control the attack. May be a variety of diseases lead to the diencephalon
Abnormal discharge caused by the site.
Headache after head injury
Early headache and brain injury with soft tissue injury, cerebral edema, intracranial hemorrhage, hematoma, infection and so on
. Late headache is quite common, mostly debilitating, known as "traumatic bacterial neurosis" or "
Traumatic brain syndrome. "However, a significant proportion of patients have other headache manifestations either concurrently or separay,
The mechanism is also very complicated. Common vascular bacterial headache (including various types of migraine blood vessels
Bacterial headache), muscle contraction headache, cranial nerves and headache caused by scalp bacteria and so on.
