【摘要】：背景藥物濫用是公共衛(wèi)生的主要威脅之一。苯丙胺類興奮劑(Amphetamine-type stimulants,ATS)等是近十年才開(kāi)始被普遍濫用的一種新型毒品,甲基苯丙胺(冰毒)是一個(gè)廣泛濫用苯丙胺類物質(zhì)。在2011年,全球在15-64歲之間的人群0.7%的人(約3380萬(wàn))使用苯丙胺類藥物。而甲基苯丙胺仍然是苯丙胺類使用最多的,2011年占全球的71%。苯丙胺類興奮劑的濫用不僅導(dǎo)致濫用者身心健康嚴(yán)重?fù)p害,還因藥物作用的影響,濫用者在極度興奮下極易發(fā)生各種違法犯罪行為,這對(duì)社會(huì)公共安全造成極大威脅。因此,對(duì)于苯丙胺成癮的干預(yù)是一項(xiàng)刻不容緩的醫(yī)學(xué)任務(wù)和社會(huì)任務(wù)。高效低毒無(wú)成癮性戒毒藥物的開(kāi)發(fā)成為藥物依賴干預(yù)的重大難題,中藥戒毒有著悠久的歷史,中藥資源極其廣泛,每種中藥又含有數(shù)十至數(shù)百種活性成分,由于傳統(tǒng)藥物依賴動(dòng)物模型的限制,使得戒毒藥物的高通量篩選難以開(kāi)展。國(guó)內(nèi)甲基苯丙胺藥物依賴動(dòng)物模型研究主要以神經(jīng)細(xì)胞和大、小鼠動(dòng)物模型為主,由于試驗(yàn)經(jīng)費(fèi)和試驗(yàn)室條件的限制,國(guó)內(nèi)大多數(shù)試驗(yàn)室都未能建立藥物依賴猴模型。斑馬魚作為一種理想的模式生物在生命科學(xué)領(lǐng)域被廣泛的應(yīng)用,特別在人類疾病模型和藥物高通量篩選方面,已成為斑馬魚研究的熱點(diǎn),但國(guó)內(nèi)外對(duì)甲基苯丙胺藥物依賴斑馬魚模型報(bào)道都很少。在戒毒中藥和活性成分高通量篩選方面,現(xiàn)有的大小鼠模型,乃至恒河猴模型由于試驗(yàn)周期長(zhǎng)、用藥量大、費(fèi)用高昂等因素,使戒毒藥物的高通量篩選難以開(kāi)展,而斑馬魚模型的特性使之成為尋找有效藥物的最佳選擇。與嚙齒類動(dòng)物甲基苯丙胺藥物依賴模型相比,斑馬魚模型的研究起步較晚,整體生物學(xué)體征及神經(jīng)機(jī)制有待進(jìn)一步研究。實(shí)驗(yàn)?zāi)康?.建立小鼠和成年斑馬魚的甲基苯丙胺CPP動(dòng)物模型,觀察小鼠和成年斑馬魚CPP效應(yīng),從行為學(xué)方面來(lái)對(duì)比小鼠和成年斑馬魚兩種模型的依賴效果,同時(shí)用中藥有效成分鉤藤堿進(jìn)行干預(yù),對(duì)比觀察形成依賴后不同動(dòng)物模型的行為變化。2.采用免疫組化法,觀測(cè)甲基苯丙胺條件性位置偏愛(ài)小鼠和成年斑馬魚腦內(nèi)TH、NR2B、GluR1陽(yáng)性細(xì)胞數(shù)目的改變及中藥活性成分鉤藤堿對(duì)其干預(yù)后變化情況的對(duì)比。3.采用蛋白免疫印跡(Western

[Abstract]:Background drug abuse is one of the major threats to public health. Amphetamine-type stimulants (ATS) is a new type of drug that has been widely abused for nearly ten years. Methamphetamine (methamphetamine) is a widespread abuse of amphetamines. In 2011, 0.7% of people around 15-64 years of age (about 33 million 800 thousand) Methamphetamines are used. Methamphetamine is still the most commonly used amphetamine, and the abuse of 71%. amphetamine type stimulants worldwide in 2011 not only causes serious physical and mental health damage to abusers, but also because of the effect of drug effects, abusers are vulnerable to all kinds of criminal offenses under extreme excitement, which is a social security for public safety. It is a great threat. Therefore, the intervention of amphetamine addiction is an urgent medical task and social task. The development of high efficiency and low toxicity and unaddictive drug addiction has become a major problem in drug dependence intervention. The traditional Chinese medicine has a long history, and the resources of traditional Chinese medicine are extremely wide, and each kind of Chinese medicine contains dozens to hundreds of active forms. Due to the limitation of traditional drug dependence on animal models, the high throughput screening of drug addicts is difficult to carry out. The domestic animal model of methamphetamine drug dependence is mainly based on neural cells and large, mouse model. Due to the limitation of test funds and laboratory conditions, most laboratory laboratories in China have failed to establish drugs. Zebrafish, as an ideal model organism, is widely used in the field of life science, especially in the human disease model and high throughput screening, which has become a hot spot in the study of zebrafish. However, the drug dependence of methamphetamine on zebrafish models at home and abroad is very few. In screening, the existing rat model, and even the Ganges RIver monkey model, is difficult to carry out because of the long test period, large dosage and high cost, and the characteristics of the zebrafish model make it the best choice for finding effective drugs. Compared with the model of the rodent methamphetamine drug dependence model, zebra zebra is the same as the zebra horse model. The study of fish model started late, and the overall biological signs and neural mechanisms need to be further studied. Objective 1. to establish the model of methamphetamine CPP in mice and adult zebrafish, to observe the CPP effect of mice and adult zebrafish, and to compare the dependence effect of the two models of mice and adult zebrafish from the behavioral aspects. An effective component of the active component of rascarine was intervened, and the behavior changes of different animal models after the formation of dependent.2. were observed by immunohistochemistry. The changes of the number of TH, NR2B, GluR1 positive cells in the brain of methamphetamine conditioned conditioned mice and adult zebrafish were observed and the changes of the survival rate of the active components of the Chinese herbal medicine were observed. Comparison of.3. using Western blotting method to observe the changes of TH, NR2B, GluR1 receptor protein expression in the brain of methamphetamine conditioned conditioned mice and adult zebrafish and the comparison of the changes of the activity of the active ingredient of Chinese medicine on the dry prognosis of the Chinese medicine..4. through the analysis of the results of different groups and indexes of two animal models. Comparison of the two models and the changing trend of different indexes after administration. Method 1. the model of conditioned place preference of mice and adult zebrafish was established with reference to the previous research results of the experimental group. From the aspect of behavior, 50 mice of the CPP effect of two models of mice and adult zebrafish were compared, and the random principles were divided according to the random principles. 5 groups were: (1) blank control group, (2) methamphetamine model group, (40mg/kg) group, high dose (80mg/kg) group, ketamine (15mg/kg) group, 10 mice in each group, and group 5 was subcutaneously injected with methylphenylpropanamine 4 mg/kg every morning (8:00); (1) group injection of same volume of saline, the other treated the same Group (2); (3) and group 4 from second days (7:30, before injection of methamphetamine 30min) to the corresponding dose of hohoo base for 3 days, and the fifth group from second days before the injection of methamphetamine 15min, intraperitoneal injection of ketamine (15 mg/kg) for 3 days. All groups (16:00, interval 8h) were given saline (0.15 ml, SC) 1 times. The partition board in the middle of the box was placed in the middle. The mice were immediately placed in the white box after the first day of injection of saline or methamphetamine. The mice were placed in the black box immediately after the afternoon injection of normal saline. The mice were placed in the black box immediately after 4 days of.24 H (fifth days). The time of stay in the white box in the 5 min of the mice was recorded. 50 qualified adult zebrafish were determined by position preference: (1) normal control group, (2) methamphetamine model group, (3) low dose group (50 g/g), high dose group (1OO mu g/g) and ketamine group (150 mu g/g). The whole experiment required 9D and D1 to put zebrafish in independent CPP box for training. The water level of the CPP box is not less than 5cm to ensure sufficient water pressure. Under the normal condition of the adaptive feeding at least 2d.d3 test, all zebrafish positions prefer the box (15 min), and the Noldus animal behavior analysis system is used to track its roadmap (5 min). In D4, D6, D8, all zebrafish other than the blank group will be immersed in 200mg/L Tricaine. In the methanesulfonate solution, the methamphetamine (40 g/g) was intraperitoneally injected with a micro syringe and then placed after the training step of the non preferred box (with the medicine box) 45 min., and after the same.12h of the training step of the model, all zebrafish other than the blank group would be immersed in 200mg/L Tricaine methanesulfonate again. Anaesthesia in the liquid, using a micro syringe to intraperitoneally injected with the corresponding treatment drugs (model group injection of normal saline, low dose group injection of 50 g/g Hoo Carine solution, high dose group injection of 100 g/g rhoehoine solution, ketamine group injection of 150 g/g ketamine solution), then moved to a larger blue environment fish tank. Blank group spot The fish of the horse fish were injected with 200mg/L Tricaine methanesulfonate solution after the injection of physiological saline. The other treatments were in accordance with the model group,.D5 and D7 were given the same time as D4, given the zebrafish injection of the same volume of fish with physiological saline, and then placed them in the preferred box (non companion medicine box) 45 min. to the zebra fish according to the same steps. Training. After the last injection of 24h (D9), the residence time of all zebrafish and the route map of the fish tank were tested. The difference between the stay time of the drug box and the difference value.2. by immunohistochemistry was used to observe the changes in the number of TH, NR2B, GluR1 positive cells in the conditioned place of methamphetamine and the brain of the adult zebrafish. On the last day, the animal tissues of each group (the mice were taken from the whole brain, the whole head of zebra fish were taken from the 4% paraformaldehyde (PFA), and the paraffin was embedded, sectioning, immunohistochemical staining, observation and film under microscope. The distribution of the positive particles in the cells and the brown yellow granules in the cells were positive. The Image-Proplus6.0 image analysis software was used to determine the integral light density (IOD).3. of the positive cells using the Western blotting method to observe the conditioned place of methamphetamine and the TH, NR2B, GluR1 in the brain of adult zebrafish. The changes in the expression and the changes in the dry prognosis of the active components of the Chinese medicine. On the last day, the experimental animals were killed, the brain was taken, the total brain protein was extracted and the protein content was measured. The 10 x TBS, 10%SDS, 1.0MTris-HCl (PH=8.3), 1.0M Tris-HCl (PH=8.8), 1.0M Tris-HCl (PH=6.8), 1XTBST and Transfer needed for the experiment were prepared. Buffer et al. Preparation of gel, SDS-PAG electrophoresis, conversion film, one anti, two anti incubation, developing, fixing, and Metamorph software analysis of TH, NR2B, GluR1 receptor each specific band of.4. statistics method in this paper all data are analyzed with SPSS 13. All data are indicated by (x + s), if each group of comparison variance is unidirectional square Difference analysis (One-Way ANOVA), variance unhomogeneous using Welch test, variance homogeneous multiple comparison using the minimum significant difference (least significant different, LSD), variance is not homogeneous, the use of Dunnett's T3 method. Correlation analysis method, use correlation coefficient (R) method to examine the two animal models and to give Chinese Medicine active components of hochline after the prognosis. Results 1, experimental results 1, after a certain amount of methamphetamine was given to a certain amount of methamphetamine, the CPP effect was produced in both mice and adult zebrafish drug dependence models. The results were statistically significant (P0. 01) compared with the blank group (P0. 01). There was a positive correlation between positive correlation R =0.593, P=0.000.2, and TH experimental results: the number of TH positive cells in the brain of the mice and adult zebrafish methamphetamine drug dependent models increased significantly (P0.01), and improved by the intervention of Hoo Carine. There was a positive correlation between the number of TH positive cells in the brain of zebra fish and mice (r=0.408, P=0.000).Western results. The expression of TH protein in the brain of the two animal models was significantly enhanced (P0.01). The expression of TH protein in the brain of the brain was positively correlated with the mouse brain (r=0.337, P=0.000).3. The results of immunohistochemistry in NR2B experiment results: the number of NR2B positive cells in the brain of mice and adult zebrafish methamphetamine drug dependent models increased. Adding (P0.01) was improved by the intervention of Hoo Carine. Zebrafish had a positive correlation with the number of NR2B positive cells in the brain of mice (R =0.803, P=0.000).Western results: the expression of NR2B protein in the model brain of mice and adult zebrafish was enhanced (P0.01) and improved by the intervention of hoo Carine. Zebrafish and mice NR2B eggs The white expression was positive correlation (R =0.502, P=0.000).4, and the results of immunohistochemistry in GluR1 experimental results: the number of GluR1 positive cells in the brain of the mice and adult zebrafish methamphetamine drug dependence model increased (P0.01), and improved by the intervention of Hoo Carine. The number of zebra fish was positively correlated with the number of GluR1 positive cells in mice (R =0.626, P=0.000).Western junction Fruit: GluR1 expression in the brain of the mice and adult zebrafish methamphetamine drug dependence model enhanced (P0.01) and improved by the intervention of Hoo Carine. Zebrafish and mouse GluR1 protein expression was positively correlated (R =0.875, P=0.000). Experimental conclusion 1, after a certain amount of methylphenylpropanamine was given, the mice and adult zebrafish drug dependence models produced CP P effect, by correlation analysis, the effect of the two models of animal CPP is significantly correlated, suggesting that the zebrafish drug dependence model is a successful, stable, replicable.2, compared with the mature rodent (mouse) drug dependence model, through the analysis of the three indications of immunofluorescence and Western results of TH, NR2B, GluR1, mice and adult zebrafish. There was a positive correlation between the two groups of drug dependence models, suggesting that the mechanism of molecular biology of the two animal models was similar. The zebrafish animal model was similar to the rodent model to a large extent.3. By the prognosis of the hooked Hoo base, the behavior of the drug dependence model of mice and adult zebrafish, and the three indexes of TH, NR2B, and GIuR1 were all adjusted. There is a positive correlation between the two groups of data, suggesting that the effect of hooked Carine is similar to the two models. The zebrafish model has the biological advantages of short period, less drug use and small size, which is more beneficial to drug research and drug screening.
