挤压综合征大鼠血清酶浓度变化的初步研究

目的观察挤压伤大鼠血清肌酸激酶(CK)、肌酸激酶心肌同功酶(CK-MB)浓度的变化,阐明肢体挤压伤大鼠早期是否存在心脏损伤。方法复制挤压伤大鼠动物模型,全自动生化分析仪检测血清CK、CK-MB浓度的变化。结果挤压伤后12h,血清CK、CK-MB浓度显著升高,并持续48h以上。结论肢体挤压伤早期可能有心脏损伤的存在。     

环境社会系统发展学发轫

叶文虎教授在研究可持续发展基本理论的基础上,于1999年提出了"环境社会系统发展学"的思想和概念[1],并指出这将是一门划时代的新学科.本文论述了环境社会系统发展学创立的学术和时代背景,以及这门学科的现状,提出了它的基本问题、基本内容和研究方法.     

福建省违法犯罪青少年的个性特征研究

为探讨青少年违法犯罪与个性的关系,采用艾森克个性问卷对621名13－19岁违法犯罪青少年和1371名相应年龄在校学生按不同年龄段和性别进行对照研究,发现16－19岁男性违法犯罪青少年外向性（E）、精神质（P）评分显著高于对照组（P＜0．01）,13－15岁男性违法犯罪少年精神质（P）、神经质（N）评分显著高于对照组（P＜0．01）,16－19岁女性违法犯罪青少年神经质（N）评分低于对照组（P＜0．05）,不同违法犯罪类型之间各个维度无统计学差异,表明外向性、精神质和神经质与男性青少年违法犯罪相关,倾稳性可能与女性青少年违法犯罪有关。     

The SEM observation of brain tissues and vascular corrosion cast of closed diffuse brain injuries

The morphologic changes of the closed injured brain of rats were observed by SEM. The rats either died immediately after conclusive injuries or were killed after 5 minutes to 5 days after injuries. The main changes were as follows: the diffuse disorder, twist, wave-like distortion and break of neuron fibers; axonal swelling; formation of axonal retraction balls; stripping and denotation of myelin sheath The ball-like swelling of neuron, break of neuron membrane and vascular wall, and microthrombus formations were also observed. These damages worsened with prolongation of surviving time of the rats. The axonal retraction ball appeared 8 hours after the injury and was approximately 3-5 cm in diameter, and developed to 7-8 cm after 3-5 days. It is observed that frontal lobe, cerebellum and brain stem were severely damaged.     

A pathological study of hemorrhage and necrosis of pancreas due to poisoned death: analysis of 22 cases

Pathological changes of pancreas in 22 cases died of intoxication were studied and the mechanism was discussed. The results showed that: in death cases by eating of toxicants, the hemorrhage and necrosis of pancreas is extensive mainly in caput and corpus, while inhaling of carbon monoxide is focal in corpus and cauda.     

Polymorphism and haplotype study of Y-chromosomal multi-STRs loci in Han population in Guangzhou

Using polymerase chain reaction and silver stain, polymorphism and haplotype study of Y-chromosomal multi-STRs loci: DYS19, DYS389I/II, DYS390 were studied. 111 samples of male were collected from Guangzhou area. 5 alleles were determined in DYS19 locus, 4 alleles in DYS389I locus, 5 alleles in DYS389II locus and 5 alleles in DYS390 locus. Compared with other racial populations, differences of distribution of allele frequencies existed significantly. 72 haplotype were present in this study.     

The use of the Foster & Freeman Fx5 Fibre Finder in forensic textile examinations.

The Fx5 Fibre Finder has been developed by Foster & Freeman Ltd to automatically search tape lifts for coloured fibres specified by the operator. Experiments and casework studies have been conducted to assess primarily the performance of the instrument but also, where possible, to compare it with manual searching. Tape lifts have always been manually searched at this laboratory and it is a laborious task. The use of a machine such as the Fx5 would release a scientist from many hours of low power microscopy to be free for other duties and therefore could be a valuable labour saving device in forensic textile examination.     

监禁死亡的法医病理学研究

目的　探讨监禁死亡的法医病理学及其流行病学特点。方法　对华西医科大学法医学系 1 987～ 1 998年所作 5 2例监禁死亡案例病理材料进行统计分析。结果　性别 :5 2例均为男性。年龄 :从 1 8岁～ 70岁 ,以 2 1至 4 0年龄段为主 ( 6 1 5 3% )。民族 :汉族人居多 ( 84 6 1 % )。职业 :待业、农民、工人最多 ( 75 % )。婚姻状态 :已婚者占多数 ( 5 9 6 1 % )。监禁原因 :以抢劫、偷盗为主 ( 6 3 4 6 % ) ,首次被监禁为主 ( 94 2 3% )。监禁死亡时间以 3个月常见 ( 36 5 4 % ) ,死亡地点以派出所、看守所及监狱常见 ( 82 6 9% )。死亡方式 :自然死亡以肺结核及支气管炎为主 ( 4 6 1 5 % ) ,自杀以自缢及高坠为主 ( 4 8 1 5 % ) ,少部分为他杀 ,以同监犯人打死为主( 5 76 % )。结论　监禁中死亡与多种因素有关 ,防止该类事件的发生需要各方面的努力。     

Marine taphonomy: adipocere formation in a series of bodies recovered from a single shipwreck.

Taphonomy of marine environments has been studied mostly from individual cases. The formation of adipocere, or "grave-wax," is an important indicator of the postmortem interval. In the present paper, the conditions and the timing of adipoceric formation are observed in a series of 15 cadavers recovered at different times, over a period of 433 days, from the same contained environment. Initial foci of adipocere on the subcutaneous tissue of the cadavers were detected as early as 38 days from the time of immersion in cold (10-12 degrees C) sea water. The discrepancies between our findings and previous reports on the correlation between time since death and decomposition stages in marine environments are discussed.     

宪政:依法治国的核心

依法治国并不必然实现法治国家 ,必须对其予以限定。宪法的限制是第一层次的限定 ,宪政是第二层次的限定。宪政是依法治国的核心 ,实行宪政是实现法治国家的保证。实行宪政必须对权力进行三个层次的制约 ,即规范制约、权力制约和权利制约 ,进而要求有高度权威的宪法 ,实行政府权力分立和大力发展市场经济
