Brainstem changes in death from head injury YAO QINGSONG;PENG XINGPING;LIANG SHANGYOU;ET AL (INSTITUTE OF FORENSIC SCIENCES OF GUANGZHOU;GUANGZHOU 000 P. R. CHINA) 1999, 0(3): 129-130+.  Abstract ( 1873 )   The cortex and brainstem changes in death from head injury were observed. There were hemorrhage, edema and neuron necrosis in brain injury group, and also in disputed group of brainstem injury. Related Articles | Metrics

Forensic medical identification of death due to poisoning of tetrodotoxin in puffer fish CHEN LONG;LI ZHONG;ZHAO ZIQIN(DEPARTMENT OF FORENSIC MEDICINE;SHANGHAI MEDICAL UNIVERSITY;SHANGHAI 000;P. R. CHINA) 1999, 0(3): 131-132+.  Abstract ( 2249 )   One case died of poisoning of tetrodotoxin in dry fugu fillet was reported. Through the detailed forensic examination for this lethal case, many questions about forensic medical identification of death due to poisoning of tetrodotoxin was discussed and its medico- legal significance was also discussed. In particular, emphasis was placed on the details of a case, extraction of TTX in specimen, quantitative detection of TTX, purplish mouth and nails, dilatation of stomach and intestines, excluding other causes and combining animal experiment in order to get definite forensic medical identification.

Cardic death and apoptosis of myocardium CHEN YIJIU;WU REN;HUANG XIAOHUA(INSTITUTE OF FORENSIC SCIENCES;MINISTRY OF JUSTICE;P. R. CHINA;SHANGHAI 000;P.R. CHINA) 1999, 0(3): 133-134+.  Abstract ( 1958 )   TdT- mediated Dutp nick end labeling (TUNEL) method was applied to detect apoptosis of myocardium of corpses dying from cardiac death. For arteriosclerotic coronary heart death, diffused apoptosis was observed around the border zones of histologically infarcted my- ocardium, and in the epithelial and smooth muscle of arteries. Few apoptosis cells were present for hypertensive heart death, and none for corpses dying from falling and hanging. Myocardium apoptosis may provide a new target for heart failure.

Enzymehistochemical and immunohistological changes of skeletal muscle motor end-plates and muscle fibers and their relation to the time of death WANG HUIJUN;ZHANG CHUNMING;XIONG XIKAI;ET AL (DEPARTMENT OF ULTRASTRUCTURAL PATHOLOGY;RESEARCH CENTER OF EXPERIMENTAL MEDICINE;TONGJI MEDICAL UNIVERSITY;WUHAN 000;P.R. CHINA) 1999, 0(3): 135-137+.  Abstract ( 1919 )   In order to investigate the relationship between the retrograde changes of the skeletal muscle and the time of death in various postmortem intervals (PMI), a systemic study of the enzymehistochemical activity of ACHE, SDH, LDH, Ca~(2+)-ATPase and the immunohistochemical reaction of SYN in motor end-plates and muscle fibers was conducted in rats under different temperatures and at various PMI. The results were analyzed and compared by an image processing system. It was found that these changes were related to the PMI, especially AChE changes. The AChE could be used as a sign-enzyme of skeletal muscle to date death. Related Articles | Metrics

Evaluation of anti-muscle actin monoclonal antibody HHF35 in the diagnosis of early myocardial infarction HU BINGJIE;CHEN YUCHUAN;ZHU JIAZHEN;ET AL (DEPARTMENT OF FORENSIC PATHOLOGY;SUN YAT-SEN UNIVERSITY OF MEDICAL SCIENCES;GUANGZHOU 00;P. R. CHINA) 1999, 0(3): 138-139+.  Abstract ( 1983 )   In order to explore the specificity of anti-muscle actin monoclonal antibody HHF35 in the postmortem diagnosis of early myocardial infarction, the changes of HHF35 staining in the infarcted myocardia and other non-infarcted myocardia with direct or indirect myocar- dial injury were studied with immunohistochemical S-P method. The results showed that the loss of HHF35 staining of different degrees was found in the infarcted myocardia, but also in the other non-infarcted myocardia with direct or indirect myocardial injury, such as cardiac contusion, myocarditis, hemorrhagic shock, electrocution, mechanical asphyxia. So it should be cautious in diagnosing early myocardial infarction with HHF35 immunohistochemisrty. Related Articles | Metrics

PCR-based DNA analysis of vWA31A, TH01, F13A01, FESFPS, TPOX and CSF1PO JIANG BIN;GUO JINGYUAN;LIANG SHANGQIU (DEPARTMENT OF FORENSIC. SCIENCE;THE SUN YAT-SEN UNIVERSITY OF MEDICAL SCIENCE;GUANGZHOU 00;P. R. CHINA) 1999, 0(3): 141-143+.  Abstract ( 1967 )   The allele and genotype frequencies of 6 tetranucleotide STR loci were investigated in a sample of 132 unrelated individuals from Chinese Han population. The PCR products were analyzed on 6% denaturing PAGE and detected using fluoreseently labeled primers in an automated 377 sequencer(PE). All loci meet Hardy- Weinberg equilibrium. There was no random association of alleles among the 6 loci. The allele frequencies were compared with other population databases. Except locus vWA31A, the observed heterozygosity at other 5 loci was significantly lower than that reported in Caucasian and Black population studies. The calculated DP=0.99999, PE=0.9708, pM=1.059×10~(-5). The allelic frequency data can be used in forensic identification and paternity testing. Related Articles | Metrics

Population study of the CSF1PO, TPOX and TH01 STR polymorphisms in east China QUE TINGZHI;LI LI;LIN YUAN;ET AT (INSTITUTE OF FORENSIC SCIENCES;MINISTRY OF JUSTICE;SHANGHAI 000;P. R. CHINA) 1999, 0(3): 144-146+.  Abstract ( 2048 )   Allele and genotype frequencies of four short tandem repeat loci were determined in a population sample from east China by using PCR and fluorescence techniques. After denaturing PAGE, 9 alleles were identified for CSF1PO, 8 alleles for TPOX, and 7 alleles for TH01. All loci met Hardy-Weinberg expectations. In addition, the theoretical values of these loci for paternity and forensic casework were evaluated. Related Articles | Metrics

Analysis of 50 cases of sexual dysfunction ZHU GUANGYOU;HOU XINYI;SHEN YAN;ET AL. (INSTITUTE OF FORENSIC SCIENCES;MINISTRY OF JUSTICE;SHANGHAI 000;P. R. CHINA) 1999, 0(3): 149-151+.  Abstract ( 2019 )   Fifty cases of male sexual dysfunction were analyzed in order to investigate the incidence and causes of the erectile dysfunction in the different injuries. The results showed that the incidence of erectile dysfunction of the patients with brevic fracture and urethra injury is 62.50%, main caused by the damage of pudendal nervous and arterial system. The incidence in the patients with the spinal fracture and light spinal cord injury is 50%, caused by the damage of nervous system. The erection in the 17 cases of the patients with only one testis injury is normal. Two cases with bilateral testis injury have suffered from erectile dysfunction. Related Articles | Metrics

Medicolegal Appraisals of 22 Cases of Ocular Penetration SHI WEIDONG;HU JIANQIN;WANG KONGBAO (QINGDAO INTERMEDIATE PEOPLE'S COURT;QINGDAO;SHANDONG 0 P. R. CHINA) 1999, 0(3): 153-153+155+190.  Abstract ( 2029 )   22 cases of ocular penetration injury were analyzed and a clinical criteria of the injury's degree was proposed. The reasons causing ocular penetration and the characteristics of injuries were discussed. Related Articles | Metrics
