蒙古族颅颌面软硬组织三维X线头影测量的临床意义

目的：研究中国蒙古族正常He成年人颅颌面软硬组织三维X线头影测量数据在临床中的作用。方法：选择符合正常He标准的蒙古族成年人98名（男女各半）,对颅颌面软、硬组织进行三维X线头影测量分析。结果：①颅颌面软组织的测量：蒙古族与汉族相比,面型较平直,面部较宽;与美国白人相比,蒙古族的上唇位于下唇前方,美国白人的上唇位于下唇后方。相对国人汉族而言,蒙古族上、下唇位置均靠后;蒙古族本民族的面型女性比男性宽而短。②颅颌面硬组织的测量：与蒙古族本民族相比,线距有性别差异,角度无性别差异,同一受检者左右相同项目测量,结果不完全一样。与不同民族相比,线距在矢状、横向、垂直三维方向与广东人、西安人有显著差异。结论：①蒙古族正常He成年人颅颌面左右侧的软硬组织存在着属于正常范围的不对称现象;②与不同民族和种族相比,蒙古族颅颌面软、硬组织形态具有明显的性别差异和种族特点;③本研究获取了蒙古族正常He成年人颅颌面软、硬组织的三维X线测量数据,建立了蒙古族自己的数据库;④蒙古族成年患者在正颌外科和牙齿正畸的诊断、设计和治疗中,应参考本民族颅颌面软硬组织的正常值和属于正常范围的面部左右不对称现象。

3种抗肿瘤有毒蒙药的研究进展

随着社会发展和生活水平的提高,恶性肿瘤已经成为影响人类健康的重大疾病之一。有毒蒙药在治疗疾病及救治疑难杂症中具有重要作用。多种有毒蒙药有一定的抗肿瘤作用,且有着良好的治疗效果,但由于其本身的毒性,使其在临床上的应用受到很大的限制。蒙医在实践中不断摸索出有毒蒙药的多种减毒方法,如采用配伍、炮制等减毒手段进行处理,以达到降低毒性、提高疗效的作用。通过对3种代表性有毒蒙药斑蝥Mylabris、草乌Aconiti Kusnezoffii Radix、瑞香狼毒Stellerae Chamaejasmes Radix的抗肿瘤作用、毒性机制及减毒策略进行综述,为其临床用药及新药开发提供依据。     

A mammalian model of optic-flow utilization in the control of locomotion

Summary Gibson (1966, 1979) and Lee (1976) have described the potential usefulness of optic-flow information for the control of locomotion. One variable that might be particularly important for an animal approaching a target is time-to-collision, which Lee argues is most efficiently specified by the tau margin (the inverse of the relative rate of expansion of the target image on the retina). In humans, most empirical studies of optic flow have required perceptual judgements or have examined catching/intercepting behaviours. In animals, most studies have been strictly observational. This is particularly true for mammals, where there has been no experimental work of any kind looking at the control of locomotion. The present experiment demonstrates that the Mongolian gerbil (Meriones unguiculatus) uses time-to-collision information to control deceleration as it runs towards a target. The development of this animal model will aid investigation of the neural circuitry underlying optic flow utilization in motor control.

Transient increase of synapsin-I immunoreactivity in the mossy fiber layer of the hippocampus after transient forebrain ischemia in the mongolian gerbil

Synapsin-I is a vesicular phosphoprotein, which regulates neurotransmitter release, neurite development, and maturation of synaptic contacts during normal development and following various brain lesions in adulthood. In the present study, we have examined by immunohistochemistry possible modifications in the expression of synapsin-I in the hippocampus of Mongolian gerbils after transient forebrain ischemia. The animals were subjected to 5 min of transient forebrain ischemia through bilateral common carotid occlusion, and were examined at different time-points post-ischemia. Transient forebrain ischemia produces cell death of the majority of CA1 pyramidal neurons of the hippocampus and polymorphic hilar neurons of the dentate gyrus. This is followed by reactive changes, including synaptic reorganization and modifications in the expression of synaptic proteins, which provide the molecular bases of synaptic plasticity. Transient decrease of synapsin-I immunoreactivity was observed in the inner zone of the molecular layer of the dentate gyrus, thus suggesting denervation and posterior reinervation in this area. In addition, a strong increase in synapsin-I immunoreactivity was observed in the hilus of the dentate gyrus and in the mossy fiber layer of the hippocampus at 2, 4 and 7 days after ischemia. Parallel increases in synaptophysin immunoreactivity were not observed, thus suggesting a selective induction of synapsin-I after ischemia. The present results indicate that synapsin-I participates in the reactive response of granule cells to transient forebrain ischemia in the hippocampus of the gerbil, and suggest a role for this protein in the plastic adaptations of the hippocampus following injury.     

Experimental cerebral ischemia in Mongolian gerbils

Summary Behaviour of biogenic amines was studied in the brains of Mongolian gerbils subjected to unilateral occlusion of the common carotid artery. Assays on the hemispheres ipsilateral to occlusion revealed in symptom-positive animals a progressive decrease in norepinephrine and dopamine, and an increase in serotonin throughout the duration of an ischemic insult. In post-ischemic periods following the release of the clip, changes in biogenic amine levels generally conformed to the principles of a previously described maturation phenomenon, with delayed reactions occurring after the shorter ischemic insults.
