美國US多聯(lián)檢測杯簡介：

美國US單卡產(chǎn)品簡介：

【功能介紹】

可以檢測尿液中是否含嗎啡成分。從而定性判斷被測者是否吸食了嗎啡。 

【樣品要求】

用一次性尿杯收集尿樣，無需處理可直接檢測。

【檢驗(yàn)方法】

1、測試前先閱讀使用說明書；

2、用干凈尿杯取尿樣；

3、從鋁箔袋中取出檢測卡，置于干凈平坦的臺面上，用吸管；垂直滴加2-3滴尿樣到加樣孔中；

4、3-5分鐘讀結(jié)果。為確保結(jié)果的準(zhǔn)確性，請勿在5分鐘后判讀結(jié)果。

【結(jié)果解釋】

1、陽性：在反應(yīng)區(qū)內(nèi)只出現(xiàn)一條紅色質(zhì)控線。

2、陰性：在反應(yīng)區(qū)內(nèi)出現(xiàn)質(zhì)控線和反應(yīng)線兩條紅線。

3、無效：在反應(yīng)區(qū)內(nèi)質(zhì)控線未出現(xiàn)，需重新測試。

【注意事項(xiàng)】

1、檢測卡在室溫下一次性使用，不得重復(fù)使用；

2、檢測卡從鋁箔袋中取出后應(yīng)在30分鐘內(nèi)盡快使用

3、3~5分鐘內(nèi)判定結(jié)果，10分鐘后的結(jié)果無效

4、謹(jǐn)防檢測卡受潮，檢測卡受潮或鋁箔袋破損后，檢測卡不能使用

5、由于標(biāo)本采集時存在差異，檢測過程中可能出現(xiàn)質(zhì)控線C和反應(yīng)線T的顏色深淺或明暗不等，但只要可見，不管其顏色深淺或明暗均應(yīng)視為出現(xiàn)。

3、口服免疫
口服免疫是進(jìn)行大規(guī)模疫苗接種時zui方便的途徑，有很好的患者依從性。口服免疫可以激活粘膜免疫和系統(tǒng)性免疫反應(yīng)。但是，口服免疫zui主要的缺點(diǎn)是可能會引起免疫耐受。口服免疫的脂質(zhì)體需要在胃腸道的苛刻條件下是穩(wěn)定的，因此其脂質(zhì)體比其它免疫途徑的更復(fù)雜。傳統(tǒng)的脂質(zhì)體不能用于口服疫苗的遞送載體，因?yàn)槠湓诘竭_(dá)作用靶標(biāo)之間，就會被胃腸道內(nèi)的酶或化學(xué)降解。因此必須對脂質(zhì)體進(jìn)行修飾，以增加穩(wěn)定性、效率和在腸道內(nèi)的保留時間[110]。
4、噴霧免疫
噴霧免疫接種與病原體和免疫誘導(dǎo)部位密切相關(guān)。噴霧粒子的大小對噴霧免疫具有關(guān)鍵作用。如果粒徑大于5μm，顆粒主要分布在呼吸道的上部和中部；如果粒徑小于3μm，顆粒主要分布在下呼吸道[95]。因此，利用粒徑的大小可以特異性的針對不同部位進(jìn)行免疫，如針對由百日咳桿菌（Bordela pertussis）引起的上呼吸道感染，應(yīng)該用粒徑大于5μm米的脂質(zhì)體[95]。但是針對由肺炎鏈球菌（Streptococcus pneumoniae）引起的下呼吸道感染，應(yīng)用粒徑小于3μm米的脂質(zhì)體[114]。迄今為止，大多數(shù)脂質(zhì)體氣溶膠是由磷脂酰膽堿（phosphatidylcholines，PC）、phosphatidylethanoloamines（PE）、磷脂酰甘油（phosphatidylglycerols，PG）、陽離子脂質(zhì)和膽固醇制備而成[95]。
5、鼻內(nèi)給藥(Intranasal Administration)
相對于其它給藥途徑，鼻內(nèi)給藥具有一些優(yōu)點(diǎn)：（1）需要的抗原量較少（與口服途徑比較）；（2）產(chǎn)生*的分泌免疫[115，116]；（3）誘導(dǎo)分泌型IgA（sIgA）[117]；（4）接種免疫簡單，便于推廣；（5）產(chǎn)生更優(yōu)的系統(tǒng)性免疫反應(yīng)[118]。

Liposomes in most vaccines are nanoscale in size, but there is little insight into the relationship between the size of liposomes and the immune response. In general, liposomes are more than 500 nm in size and are easily phagocytosed by the mononuclear phagocytic system (MPS). Liposomes are readily engulfed by dendritic cells (DCs) between 20-200 nm in size endocytosed) [129]. That is, larger liposome particles are more easily cleared by MPS.
For topical immunization on the skin, particles <100 nm in size can flow into the lymph nodes through the intercellular space and interact with DC cells in the lymph nodes [130-133]. Larger liposomes (> 500 nm) are usually confined to the site of injection and are endocytosed by the skin's DC cells or monocytes, making it difficult to migrate to the lymph nodes [134]. Medium sized particles (100-500 nm) migrate actively or passively to lymph nodes.
Experiments using rats by subcutaneous injection of liposomes to study the size of its absorption and biodistribution. Liposomes are made with egg phosphatidylcholine (EPC), egg phosphatidylglycerol and cholesterol in a ratio of 10: 1: 4. The liposomes have particle sizes of 40 nm, 70 nm, 170 nm, 400 nm, and greater than 1000 nm, respectively. The results showed that the degree of lymphatic absorption and liposome size was negatively correlated. Liposomes at 40 nm were quickly absorbed by the lymphatic system (74% absorbed in 52 hours), whereas the largest liposomes (> 1000 nm) were almost undetectable in the lymphatic vessels [135].
Liposomes based on biphosphanates have been intensively studied [136]. Liposomes range in size from 80-650 nm, and these liposomes contain positive and negative charges and neutrals, respectively. The results also show that larger liposomes are easily phagocytosed by monocytes and macrophages. Liposomes of different sizes were intravenously administered to rats and rabbits and the results showed that smaller liposomes decreased monocyte activity. Liposomes with particle sizes less than 80 nm are inactive in vivo and in vitro whereas liposomes greater than 190 nm activate cytokine activity. Studies by Mann et al. Showed that 250 nm liposomes enhance the Th2 response and that about 1 μm liposomes enhance Th1 responses and stimulate high levels of IFN-γ and IgG2 antibodies [137].
The location of liposome DNA in tissues has been studied [138]. The experimental liposomes consisted of EPC, DOPE and DOTAP, encapsulating plasmid DNA encoding OVA. Liposomes have a particle size of 500 nm or 140 nm. Subcutaneous injection of liposomal DNA into mice resulted in the discovery that larger liposomal DNA particles retained the ability to inject at the injection site than small particles. Large particle liposomal DNA still failed to detect OVA-specific IgG antibodies after three immunizations, whereas IgG antibodies were detected after the second injection of small particle liposomal DNA. Three weeks after the last immunization, spleen cells were isolated for detection of the percentage of OVA-specific T cells. The amount of OVA-specific CD8 + T cells induced by large particle liposomal DNA was negligible, the amount of CD8 + T cells induced by small particles was significantly increased, and the amount of IFN-γ was also significantly increased. The results of this study show that small particle liposomes are more efficient as DNA vaccine delivery vectors.
