【預(yù)期用途】

用于待測(cè)致敏紅細(xì)胞樣本的預(yù)處理，使致敏紅細(xì)胞樣本中的待測(cè)抗體從與細(xì)胞結(jié)合的狀態(tài)中解離釋放出來(lái)。以便于使用體外診斷試劑或儀器對(duì)待測(cè)抗體進(jìn)行檢測(cè)。

【檢驗(yàn)原理】

紅細(xì)胞上的抗原與血清中抗體在適合條件下發(fā)生致敏，這種結(jié)合在一定條件下是可逆的。將已致敏的紅細(xì)胞懸浮于低pH值的甘氨酸溶液中，抗體蛋白又可以從結(jié)合的紅細(xì)胞上解離釋放出來(lái)。離心取上清解離的放散液，此液中含有從紅細(xì)胞表面解離釋放出來(lái)的抗體蛋白，經(jīng)Tris緩沖液調(diào)節(jié)pH至中性后此上清放散液可用于相關(guān)抗體的檢測(cè)和鑒定；而解離釋放后的紅細(xì)胞經(jīng)洗滌后可用于血型定型、自身抗體的吸收等。

【主要組成成份】

1.溶液I：主要組分為甘氨酸(C₂H₅NO₂)，氯化鈉(NaCl)。

2.溶液II：主要組分為T(mén)ris堿，指示劑。   

【儲(chǔ)存條件及有效期】                  

常溫（10～30℃）儲(chǔ)存，有效期1年。試劑開(kāi)瓶后在常溫（10～30℃）條件下可儲(chǔ)存6個(gè)月。

這些毛細(xì)血管網(wǎng)下行到結(jié)節(jié)部匯集形成數(shù)條垂體門(mén)微靜脈，它們下行進(jìn)入遠(yuǎn)側(cè)部，再度形成竇狀毛細(xì)血管網(wǎng)，稱(chēng)第二級(jí)毛細(xì)血管網(wǎng)。垂體門(mén)微靜脈及其兩端的毛細(xì)血管網(wǎng)共同構(gòu)成垂體門(mén)脈系統(tǒng)（hypophyseal portal system）。遠(yuǎn)側(cè)部的毛細(xì)血管zui后匯集成小靜脈注入垂體周?chē)撵o脈竇。這是1930年代確立的經(jīng)典垂體血流模式“自上而下”的概念，闡明了下丘腦控制垂體功能的基本機(jī)制。此后又通過(guò)新技術(shù)的應(yīng)用和研究，對(duì)垂體的血流模式提出了新見(jiàn)解，認(rèn)為遠(yuǎn)側(cè)部的血液可輸入神經(jīng)垂體的漏斗，然后經(jīng)毛細(xì)血管回流入下丘腦；也可流入神經(jīng)部，再逆向流入漏斗，然后再循環(huán)到遠(yuǎn)側(cè)部或下丘腦，構(gòu)成整個(gè)垂體血流在垂體內(nèi)的循環(huán)流動(dòng)。[1]  [4-5] 
下丘腦
下丘腦神前區(qū)和結(jié)節(jié)區(qū)（弓狀核等）的一些神經(jīng)元具有內(nèi)分泌功能，稱(chēng)為神經(jīng)內(nèi)分泌細(xì)胞，細(xì)胞的軸突伸至垂體漏斗。細(xì)胞合成的多種激素經(jīng)軸突釋放入漏斗處的*級(jí)毛細(xì)血管網(wǎng)內(nèi)，繼而經(jīng)垂體門(mén)微靜脈輸至遠(yuǎn)側(cè)部的第二級(jí)毛細(xì)血管網(wǎng)。這些激素分別調(diào)節(jié)遠(yuǎn)側(cè)部各種腺細(xì)胞的分泌活動(dòng)（圖11－12）。其中對(duì)腺細(xì)胞分泌起促進(jìn)作用的激素，稱(chēng)釋放激素（releasing hormone,RH）。對(duì)腺細(xì)胞起抑制作用起抑制作用的激素，則稱(chēng)為釋放抑制激素（release inhibiting hormone,RIH）目前已知的釋放激素有：生長(zhǎng)激素釋放激素（GRH）、催乳激素釋放激素（PRH）、促甲狀腺激素釋放激素（TRH）、促性腺激素釋放激素（GnRH）、促腎上腺皮質(zhì)激素釋放激素（CRH）及黑素細(xì)胞刺激素釋放激素（MSRH）等。釋放抑制激素有：生長(zhǎng)激素釋放抑制激素（或稱(chēng)生長(zhǎng)抑素，SOM）、催乳激素釋放抑制激素（PIH）和黑素細(xì)胞刺激素釋放抑制激素（MSIH）等。由此可見(jiàn)，下丘腦通過(guò)所產(chǎn)生的釋放激素和釋放抑制激素，經(jīng)垂體門(mén)脈系統(tǒng)，調(diào)節(jié)腺垂體內(nèi)各種細(xì)胞的分泌活動(dòng)；病毒而，將此稱(chēng)為下丘腦腺垂體系。反之，腺垂體產(chǎn)生的各種激素又可通過(guò)垂體血液環(huán)流，到達(dá)下丘腦，反饋影響其功能活動(dòng)
傳統(tǒng)認(rèn)為，垂體前葉僅有少量自主神經(jīng)纖維，支配前葉內(nèi)血管的舒縮；而腺細(xì)胞的分泌活動(dòng)則主要受下丘腦各種激素的調(diào)節(jié)，并無(wú)神經(jīng)的直接支配。
These capillary network down to the nodules converge to form a few pituitary-portal venules, they descend into the distal part of the re-formation of sinusoidal capillary network, said the second capillary network. The hypophyseal portal vein is formed by the pituitary gland microvessels and capillary networks at both ends of the pituitary gland. The distal part of the capillaries converge into a small vein into the periphery of the pituitary sinus. This is the concept of the "top-down" classic pituitary flow model established in the 1930s, illustrating the underlying mechanism by which the hypothalamus controls pituitary function. Then through the application of new technologies and research, put forward new ideas on the pituitary blood flow model, that the distal part of the blood can be fed into the funnel of the pituitary gland and then back into the hypothalamus through the capillaries; can also flow into the nerve, and then Reverse inflow funnel, and then recycle to the distal part or the hypothalamus, constitute the entire pituitary blood flow in the pituitary circulation. [1] [4-5]
Hypothalamus
Some neurons in the hypothalamus prefrontal and nodal regions (arcuate nucleus, etc.) have endocrine functions, called neuroendocrine cells, and axons extend to the pituitary funnel. A variety of hormones synthesized by cells are released into the first capillary network at the funnel and then to the second capillary network of the distal part via the pyloric vein. These hormones regulate the secretory activity of various glandular cells distal (Figure 11-12). Among them, the hormone that promotes the secretion of glandular cells is called releasing hormone (RH). The hormone that inhibits glandular cells is known as release inhibiting hormone (RIH). Known releasing hormones are: growth hormone releasing hormone (GRH), prolactin releasing hormone (PRH), thyrotropin Hormone releasing hormone (TRH), gonadotropin releasing hormone (GnRH), corticotropin releasing hormone (CRH) and melanocyte stimulating hormone releasing hormone (MSRH) and so on. Release inhibitory hormones are: somatostatin (or somatostatin, SOM), prolactin releasing hormone (PIH) and melanocyte stimulating hormone releasing hormone (MSIH) and so on. Thus, the hypothalamus through the release of hormones and release of inhibitory hormone, the pituitary portal system, regulating the secretion of various cells in the pituitary gland activity; the virus, this will be called the hypothalamic pituitary gland system. Conversely, the various hormones produced by the pituitary gland and through the pituitary blood circulation, reaching the hypothalamus, feedback affect its functional activity
Traditionally, there was only a small amount of autonomic nerve fibers in the anterior pituitary, controlling the contraction and contraction of blood vessels in the anterior lobe. The secretory activity of glandular cells was mainly regulated by various hormones in the hypothalamus without any direct control of nerves.
