?常用的免疫膠體金檢測技術：

（1）免疫膠體金光鏡染色法 細胞懸液涂片或組織切片，可用膠體金標記的抗體進行染色，也可在膠體金標記的基礎上，以銀顯影液增強標記，使被還原的銀原子沉積于已標記的金顆粒表面，可明顯增強膠體金標記的敏感性。 （2）免疫膠體金電鏡染色法 可用膠體金標記的抗體或抗抗體與負染病毒樣本或組織超薄切片結合，然后進行負染。可用于病毒形態(tài)的觀察和病毒檢測。 斑點免疫金滲濾法 （3）應用微孔濾膜（如膜）作載體，先將抗原或抗體點于膜上，封閉后加待檢樣本，洗滌后用膠體金標記的抗體檢測相應的抗原或抗體。 （4）膠體金免疫層析法 將特異性的抗原或抗體以條帶狀固定在膜上，膠體金標記試劑（抗體或單克隆抗體）吸附在結合墊上，當待檢樣本加到試紙條一端的樣本墊上后，通過毛細作用向前移動，溶解結合墊上的膠體金標記試劑后相互反應，當移動至固定的抗原或抗體的區(qū)域時，待檢物與金標試劑的結合物又與之發(fā)生特異性結合而被截留，聚集在檢測帶上，可通過肉眼觀察到顯色結果。該法現(xiàn)已發(fā)展成為診斷試紙條，使用十分方便。

溫度
神經(jīng)纖維的傳導速度隨溫度降低而減慢，當溫度降至0℃時，即終止傳導。據(jù)此，臨床上出現(xiàn)低溫麻醉方法。
此外，還有種屬的差異，恒溫動物與變溫動物的有髓纖維盡管直徑相同，傳導速度卻不相同，如貓的A類纖維的傳導速度為100m/s，而蛙的A類纖維只有40m/s.即使同一條神經(jīng)纖維，由于生理狀態(tài)的改變（如血液供應不足或缺氧時），其傳導速度也有明顯的改變。
（三）神經(jīng)纖維的軸漿運輸
軸漿運輸：神經(jīng)元胞體合成的分泌物必須經(jīng)軸漿流動運輸?shù)椒置诓课唬Q為軸漿運輸。
順向軸漿運輸（anterograde anxoplasmic transport）： 指自胞體向軸突末梢進行的轉運。胞體是神經(jīng)元合成代謝的中心，維持軸突代謝所需的蛋白質、軸突終末釋放的神經(jīng)肽及合成遞質的酶類等物質，均在細胞體合成，然后運至軸突末梢。快速軸漿運輸是遞質囊泡向軸突末梢的運輸；指具有膜的細胞器，如線粒體、遞質囊泡和分泌顆粒等囊泡結構的運輸，運輸速度約410mm/d.慢速軸漿運輸指胞體合成的微絲、微管及軸漿內的可溶性物質向軸突末梢的運輸（指的是由胞體合成的蛋白質所構成的微管和微絲等結構不斷向前延伸，其他軸漿的可溶性成分也隨之向前運輸），速度為1～12mm/d.
2.逆向軸漿運輸
逆向軸漿運輸指自末梢向胞體的轉運。逆向運輸除向胞體轉運經(jīng)過重新活病毒的突觸前末梢囊泡外，還能轉運末梢攝取的外源性物質，是外源性親神經(jīng)物質的轉運渠道，速度約205mm/d.神經(jīng)生長病毒子、狂犬病毒和破傷風毒素等也可通過末梢以入胞方式攝取，被逆向運輸?shù)桨w。
軸漿流動的機制迄今仍未闡明，實驗證明它是一個主動的轉動過程。有人提出遞質囊泡的快速運輸與軸突內微管和微絲的功能有關。軸漿運輸對于實現(xiàn)突觸傳遞功能、神經(jīng)纖維的營養(yǎng)作用及神經(jīng)生長與再生均具有重要意義。我們對逆向軸漿流動了解較少。運用辣根過氧病毒酶追蹤神經(jīng)纖維的起源，其原理是辣根過氧病毒酶被軸突末梢攝取后可沿逆向軸漿流被轉運到細胞體。破傷風毒素及狂犬病毒由外周向中樞神經(jīng)系統(tǒng)的轉運，也是經(jīng)逆向軸漿流動進行的。
（四）神經(jīng)的營養(yǎng)性作用和支持神經(jīng)的營養(yǎng)性病毒子
temperature
The conduction velocity of nerve fibers slows down as the temperature decreases, and when the temperature drops to 0 ° C, the conduction is terminated. Accordingly, clinically low temperature anesthesia.
In addition, there are species differences, thermostatic animals and warm-temperate animals, although the same diameter of myelinated fibers, the conduction velocity is not the same, such as cats A class fiber conduction velocity of 100m / s, while the frog's A fiber only 40m / s Even with the same nerve fiber, due to changes in physiological conditions (such as blood supply or hypoxia), the conduction velocity has also been significantly changed.
(Three) axoplasmic transport of nerve fibers
Axoplasmic transport: the secretions synthesized by neuronal soma must be transported by axoplasm flow to the secretion site, known as axoplasmic transport.
Anterograde anxoplasmic transport: refers to the transport from the body to the terminal axon. The cell body is the center of neuronal anabolism, the protein required for the maintenance of axonal metabolism, the neuropeptides released at the terminal of the axon, and the enzymes that synthesize the neurotransmitter are synthesized in the cell body and transported to the terminal axons. Rapid axoplasmic transport is the transport of vesicular vesicles to the terminal axons; refers to the transport of vesicular structures such as mitochondria, transmitter vesicles, and secretory vesicles with membranes at transport speeds of about 410 mm / d. Transport refers to the cell body synthesis of microfilaments, microtubules and axoplasm soluble substances transport to the distal axons (referring to the synthesis of protein by the cell body composed of microtubules and microfilaments and other structures continue to extend forward, the other axles Of the soluble components also will be transported forward), the speed of 1 ~ 12mm / d.
2 reverse slurry transportation
Reverse axonal transport refers to the transport of apical to the soma. Reverse transport in addition to the transport of somatic cells through the reactivation of presynaptic vesicles, but also the transport of peripheral excretion of exogenous substances, is exogenous delivery of nerve-derived substances at a speed of about 205mm / d. Nerve growth virus Zi, rabies virus and tetanus toxins, etc. can also be taken through the distal cell into the way, was transported back to the cell body.
The mechanism of axoplasm flow has not been elucidated so far. Experiments prove that it is an active rotating process. It has been suggested that the rapid transport of messenger vesicles is related to the function of microtubules and microfilaments within axons. Axonal transport of pulp for the realization of synaptic transmission, the nutritional role of nerve fibers and nerve growth and regeneration are of great significance. We know less about axial flow. The use of horseradish peroxidase enzyme to track the origin of nerve fibers, the principle is that horseradish peroxv enzymes are taken up by axonal terminals and then transported along the axial flow to the cell body. Tetanus toxins and rabies virus from the peripheral transit to the central nervous system, but also through the reverse flow of axoplasm.
