药瘾

The affected chicks acquired the morphine conditioned place preference more quickly, and maintained it much longer. Experiment 3 showed that during E5-8, injecting delta receptor antagonist naltrindole reversed the learning and memory impairment caused by morphine while delta receptor agonist DPDPE impaired learning and partial memory function. On the other hand, mu opioid receptors had little effect. As for E17-20, given naloxonazine can reverse the increases of susceptibility to morphine, and the mu receptor agonist DAGO cause the increases of susceptibility to morphine. Delta receptors have no effect.

研究结果发现：经过对鸡胚发育不同时间段的吗啡给药，胚胎期发育E5-8阶段给予吗啡的小鸡学习记忆受损最为严重，表现为学习和记忆功能的严重下降；而E17-20时段吗啡给药的小鸡更容易获得吗啡CPP且保持时间更长。E5-8阶段给予delta受体拮抗剂natrindole能够翻转吗啡对学习和记忆的损害作用，并且给予delta受体激动剂DPDPE也损害学习和部分记忆功能，mu受体作用不大。E17-20阶段拮抗mu受体能够抑制成瘾易感性的增加，激动mu受体可以增加小鸡的成瘾易感性，delta受体没有明显作用。

The painful feeling is muchlike a druggy trying to quit the drug.

就像上瘾的瘾君子要戒药一般，甚至有著瘾头要再犯的感觉踊上心头

Theories concerning drug addiction dominantly consist of Hedonics, Abnormal Learning, Motivation-sensitization and Dysfunction of Prefrontal Cortex. Models of Self-administration and Conditioned Place Preference are often applied to study drug addiction.

药物成瘾的理论假说主要包括：享乐学说、异常性学习学说、动机-敏感化学说和额叶功能异常学说；且该研究中经常采用的动物模型有自我给药模型、条件化位置偏好模型等。

METHODS: Both diastolic and systolic blood pressures repeated measures data, collected from 120 drug abusers after taking two kinds of medicine (Drug A: Xiaoyinfuzheng, Drug B: Kelening), were analyzed by multivariate random coefficients model. The fixed effect parameters matrix x of model coefficients were estimated by using least squares estimation method, the effects between treatment groups were compared and the variancecovariance matrices of random effect were also estimated.

对两种药物（A药：消瘾扶正胶囊，B药：可乐宁）治疗120例患者后的舒张压和收缩压重复观测数据进行多变量随机系数模型分析，对模型系数的固定效应参数矩阵ξ作最小二乘估计并进行组间比较，同时估计随机效应的方差协方差矩阵，分析方法用SAS/IML软件编程得以实现。

ConclusionIt showed that there might exist HIV infection is some of HIV seronegative IVDUS at high risk of HIV infection.

结论抗-HIV阴性的静脉药瘾高危人群，存在潜在HIV感染。

Objective The study was designed to investigate whether there existed provirus HIV DNA in the liver tissues of intravenous drug users with seronegative results of anti-HIV test.

目的 了解血清抗-HIV阴性的静脉药瘾者肝组织是否存在前病毒HIV DNA。

Detoxing and withdrawals are not much fun,but I guess they're pretty much the same thing.

停止服药和戒除药瘾都不是好玩的，不过，我想它们差不多也就是一回事。

While working with cocaine for nerve block anesthesia, he and some of his associates became addicted.

在研究可卡因用于神经阻滞麻醉的过程中，他和部分助手染上了药瘾。

Results Right heart infected endocarditis were always superimposed on patients with congenital heart disease or drug addicts. Pulmonary embolisms were the most distinct characteristics in this patients. Echocardiography had a important role on diagnosis of right endocarditis.

结果 右心感染性心内膜炎主要发生于先天性心脏病，其次为静脉药瘾者；其突出临床特点为肺栓塞；超声心动图对诊断右心感染性心内膜炎有重要价值。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
