阿鲁科尔沁蒙古族民间植物药与蒙药和中草药的相关性研究

在调查阿鲁科尔沁旗蒙古族民间药用植物及相关传统知识的前提下,从植物种类、药用部位、治疗的疾病和用药方法等方面,同蒙药与中草药进行了对比分析。结果表明,有不同程度的一致性的同时,民间药也有它本身的特色而存在某些不一致性。民间药与蒙药的一致性说明了它们属于相同的系统;民间药与中草药的一致性说明了蒙古族和汉族之间存在着传统药知识的交流和文化的渗透现象;而不一致性则反映了当地蒙古族民间药用植物知识的丰富性及进一步深入挖掘的价值。

Intraventricular administration of the neurotrophic factor midkine ameliorates hippocampal delayed neuronal death following transient forebrain ischemia in gerbils

Midkine (MK) is a growth factor with neurotrophic activities, and is expressed during the early stages of experimental cerebral infarction in rats in the zone surrounding the infarct. To evaluate in vivo activity of MK in preventing neuronal death, MK produced in yeast (Pichia pastoris) was administered into the brain ventricle immediately before occlusion of the bilateral common carotid artery of Mongolian gerbils. MK administration at the dose of 0.5-2 microg immediately before occlusion was found to ameliorate delayed neuronal death in the hippocampal CA1 region caused by transient ischemia 7 days after the insult. The hippocampal neurons of the MK-administered gerbils tended to degenerate 14 and 21 days after the insult, but their numbers remained higher than those in saline-administered controls; however, the hippocampal neurons were degenerated 28 days after the insult. MK administration at 2 h after occlusion did not ameliorate the neuronal death. These findings suggested that the therapeutic time window was narrow. The two to four times repeated administration of 2 microg MK immediately before and at 1, 2, or 3 weeks after the occlusion were not significantly different for the hippocampal neuronal death at 28 days after the insult compared with a single injection, but were significantly effective compared with vehicle administration alone. These findings suggested that the therapeutic time window was relatively narrow. The potent neuroprotective activity of MK observed in vivo suggested that MK might be useful as a therapeutic reagent for prevention of neuronal death in neurodegenerative diseases.

普通环境和清洁级环境中长爪沙鼠寄生虫感染状况观察

目的　了解两种不同环境中饲养的长爪沙鼠寄生虫感染状况。方法　根据 2 0 0 1年中华人民共和国国家标准GB 1 4 92 2 1— 2 0 0 1《实验动物寄生虫学等级及监测》和GB T1 84 4 8 1～ 1 84 4 8 1 0— 2 0 0 1《实验动物寄生虫学检测方法》 ,参考实验动物小鼠、大鼠、豚鼠和地鼠寄生虫等级及检测办法进行检测。结果　饲养于普通环境的 1 5笼 80只长爪沙鼠体表寄生虫感染率为 3 75 % (3 80 ) ,体内寄生虫中卡氏肺孢子虫感染率为 6 2 34% (4 8 77) ,鼠三毛滴虫感染率为 86 2 5 % (6 9 80 ) ;饲养于清洁级环境的 7笼 2 3只长爪沙鼠中 ,卡氏肺孢子虫的感染率为 6 9 5 6 % (1 6 2 3) ,鼠三毛滴虫感染率为 6 9 5 6 % (1 6 2 3)。结论　净化后饲养于普通环境中的长爪沙鼠与净化后饲养于清洁级中的个体相比 ,二者体表寄生虫感染的状况有一定差别。但是 ,卡氏肺孢子虫和鼠三毛滴虫的感染情况似乎无明显差别。

Experimental pneumococcal otitis media: longitudinal studies in the gerbil model

In order to ascertain that the Mongolian gerbil, Meriones unguiculatus, is an acceptable model for studying the development of chronic from acute otitis media, we used previously published methods for experimental otitis media in a longitudinal study of the acute disease and sequellae. The gerbil was found to be susceptible to as few as 30 viable Streptococcus pneumoniae type 3 cells, indicating that only a few viable pathogens are able to cause the disease. Untreated experimental infections with S. pneumoniae type 23 resulted in a mild, self-limiting disease with little permanent sequellae, while S. pneumoniae type 3 produced severe disease characterized by an acute phase of from 2 to 3 weeks, followed by the development of new bone formation and a vascularized granulation tissue which persisted throughout the 13-week study. Viable pneumococci could be recovered from the middle ears for only two weeks. We conclude that the gerbil is a useful model for otitis media.     

Elicitation of water ingestion in the Mongolian gerbil (Meriones unguiculatus) by intracranial injections of angiotensin II and 1-norepinephrine

Intracranial injections of Angiotensin II (AII) through permanent brain chemodes aimed for the lateral hypothalamic, lateral preoptic, or septal region evoked drinking of tap water from Mongolian gerbils in normal water balance. When lettuce was the only available free water source, AII injections elicited prolonged lettuce-eating responses. l-Norepinephrine injections did not elicit eating of food pellets but, like AII, proved to be a reliable and potent dipsogenic agent. Carbachol, a cholinergic agonist, failed to elicit any ingestive behaviors over a wide dose range. The species-typical foot-thumping behavior of the gerbil was seen during some tests with all drugs utilized. It is suggested that the dipsogenic property of AII across a wide variety of species reflects the nature of a primitive, i.e., phylogenetically old, brain mechanism shared by most mammals to deal with problems of water economy, while the organization and utilization of other central neurochemicals in thirst-related substrates may vary among species.     

蒙古族高血压遗传及环境危险因素分析

目的探讨蒙古族高血压的遗传环境影响因素。方法在现况调查基础上,以其中无血缘关系的579名蒙古族人（高血压者298人,正常血压者281人）为研究对象进行病例对照研究。调查相关的环境因素并采集血样,对肾素基因一处新发现的插入/缺失（insertion/deletion,I/D）多态性、血管紧张素转换酶基因的插入/缺失（ivseaion/deletion.I/D）多态性,采用PCR技术结合凝胶电泳和银染方法进行基因分型。采用非条件Logistic回归模型进行遗传、环境多因素分析。结果年龄、体质指数（BMI）、每日饮酒量、肾素基因I/D多态性对高血压的发生差异有统计学意义（P〈0.05）。年龄每增加10岁发生高血压的危险性是增加前的1.28倍（OR95%CI=05～1.57）;BMI≥24 kg/m^2发生高血压的危险性是BMI〈24 kg/cm^2的2.44倍（OR95%CI=1.66～3.64）;每日饮酒量每增加一个等级发生高血压的危险性是增加前的1.61倍（OR95%CI=1.25～2.08）;肾素基因I/D多态性以II基因型为参照,ID、DD基因型的OR分别为2.39（OR95%CI=1.31～4.48）,2.41（OR95%CI=1.27～4.68）。结论超重或肥胖、长期过量饮酒是蒙古族人群高血压的危险因素,肾素基因I/D多态性D等位基因可增加蒙古族人群高血压的危险性。
