美国US多联检测杯简介：

美国US单卡产品简介：

【功能介绍】

可以检测尿液中是否含吗啡成分。从而定性判断被测者是否吸食了吗啡。 

【样品要求】

用一次性尿杯收集尿样，无需处理可直接检测。

【检验方法】

1、测试前先阅读使用说明书；

2、用干净尿杯取尿样；

3、从铝箔袋中取出检测卡，置于干净平坦的台面上，用吸管；垂直滴加2-3滴尿样到加样孔中；

4、3-5分钟读结果。为确保结果的准确性，请勿在5分钟后判读结果。

【结果解释】

1、阳性：在反应区内只出现一条红色质控线。

2、阴性：在反应区内出现质控线和反应线两条红线。

3、无效：在反应区内质控线未出现，需重新测试。

【注意事项】

1、检测卡在室温下一次性使用，不得重复使用；

2、检测卡从铝箔袋中取出后应在30分钟内尽快使用

3、3~5分钟内判定结果，10分钟后的结果无效

4、谨防检测卡受潮，检测卡受潮或铝箔袋破损后，检测卡不能使用

5、由于标本采集时存在差异，检测过程中可能出现质控线C和反应线T的颜色深浅或明暗不等，但只要可见，不管其颜色深浅或明暗均应视为出现。

3、口服免疫
口服免疫是进行大规模疫苗接种时zui方便的途径，有很好的患者依从性。口服免疫可以激活粘膜免疫和系统性免疫反应。但是，口服免疫zui主要的缺点是可能会引起免疫耐受。口服免疫的脂质体需要在胃肠道的苛刻条件下是稳定的，因此其脂质体比其它免疫途径的更复杂。传统的脂质体不能用于口服疫苗的递送载体，因为其在到达作用靶标之间，就会被胃肠道内的酶或化学降解。因此必须对脂质体进行修饰，以增加稳定性、效率和在肠道内的保留时间[110]。
4、喷雾免疫
喷雾免疫接种与病原体和免疫诱导部位密切相关。喷雾粒子的大小对喷雾免疫具有关键作用。如果粒径大于5μm，颗粒主要分布在呼吸道的上部和中部；如果粒径小于3μm，颗粒主要分布在下呼吸道[95]。因此，利用粒径的大小可以特异性的针对不同部位进行免疫，如针对由百日咳杆菌（Bordela pertussis）引起的上呼吸道感染，应该用粒径大于5μm米的脂质体[95]。但是针对由肺炎链球菌（Streptococcus pneumoniae）引起的下呼吸道感染，应用粒径小于3μm米的脂质体[114]。迄今为止，大多数脂质体气溶胶是由磷脂酰胆碱（phosphatidylcholines，PC）、phosphatidylethanoloamines（PE）、磷脂酰甘油（phosphatidylglycerols，PG）、阳离子脂质和胆固醇制备而成[95]。
5、鼻内给药(Intranasal Administration)
相对于其它给药途径，鼻内给药具有一些优点：（1）需要的抗原量较少（与口服途径比较）；（2）产生*的分泌免疫[115，116]；（3）诱导分泌型IgA（sIgA）[117]；（4）接种免疫简单，便于推广；（5）产生更优的系统性免疫反应[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.
