Immunohistochemical study on myocardial acute ischemia reperfusion injury in rats with anti-FOS protein antibody MA MENGYUN;XU XIAOHU;LUO BIN;ET AL. (DEPARTMENTOF FORENSIC PATHOLOGY;SUN YAT-SEN UNIVERSITY OF MEDICAL SCICNCES;CUANGZHOU 00;P. R. CHINA) 1999, 0(4): 193-195+.  Abstract ( 273 )   To investigate law of FOS protein induced by myocardial ischemia reperfusion (MI/R) in acute period, amodel in 20 anaethetized SD rats was established. Ratswith normal and ischemia were used as control groups.Specimens were studied immunohistochemically with c fos antibody. Afer ischemia 20 minutes, followed by 30minutes reperfusion, the area of MI/R showed nuclei ofmyocytes positive staining in cryosection slides. In C2group, the area showed nuclei of myocytes (37. 76%±9. 66% ) positive staining weakly. In C3 group, nuclei ofcardiac myocytes(40. 34% ± 3. 32% ) was significantlypositive. In C4 group it began to attenuate(35. 36% ±4. 81% ). The myocardium in normal and ischemic control groups showed negative staining. No changes wereseen with HE staining. Our data indicated that immunohistochernical method may reveal acute MI/R injury ofischemia 20 min and reperfusion 30 min with anti - FOSprotein staining and there is problely a peak between 60 -120min after reperfusion. It is possible that the method beused to diagnose sudden cardiac death in forensicmedicine. Related Articles | Metrics

An experimental study of corpse decay degree and timing of death CHEN LUSHI (CUIZHOU COLLEGE OF PUBLIC SECURITY CADRES;CUIYANG 000;P. R. CHINA ) 1999, 0(4): 196-198+.  Abstract ( 206 )   In this study, we put dead pigs indoors, outdoors and underground respectively, and kept a detailed record of the natural decay process, especially the tension of the pig's abdomen produced by corruptive gas. The result showed that the decay speed was closely related to temperature, humidity, rainfall, position of corPses on the ground, insect parasitism. The obtained data could pro-vide an important referential basis for inferring time after death. Related Articles | Metrics

Changes of potassium and sodium content in erythrocyte of rabbit cardiac blood after death and timing of death CU JIANPING;LIU AIBING;SONG MEI (THE PEPOLE'SPROCURATORATE OF SHIJIATHUANG;SHLJIAZHUANG 00000;P. R. CHINA) 1999, 0(4): 199-200+.  Abstract ( 161 )   We studied the changes of potassium and sodiumcontents in erythrocytes and the activity of ewthrocytemembrane Na+ - K+ - ATPase in 4o cardiac blood samples of rabbit corpses at different postmortem intervals(PMI). The erythrocyte potassium content (RBCK) decreased linearly as the PMI increased (R = - 0. 829, P＜0. 025). during postmortem 48 hours. The erythrocytepotassium content and the time after death had significantcorrelation. The activity of erythrocyte mernbrane Na+ -K + - ATPase had no significant changes over postmortem48 hours.

HLA-DRB1 Typing by PCR-sequence specific primers for paternity determination LIU LIMIN;LIANG JIAN;WANG BAOJIC;ET AL. (DEPARTMENTOF FORENSIC MEDICINE;CHINA MEDICAL UNIVERSITY;SHENYANG 000;P. R. CHINA) 1999, 0(4): 201-203+.  Abstract ( 171 )   HLA-DRB1 typing by PCR - SSP technique was first used for patemity testing. The analysis of 42 paternity cases shows that this identification method is simple, Thst and reliable and has high exclusion probability of paternity (66. 3% ). This method can also be applied to the study of transplantation, HLA associated disease and anthropogenesis Related Articles | Metrics

Segmental analysis of hair from meperidine abusers and evaluation of the results SHEN MIN;XIANG PING;SHEN BAOHUA;ET AL. (INSTITUTE OFFOREUSIC SCICNCES;MNISTRY OF JUSTICE;SHANGHAI000;P R. CHINA) 1999, 0(4): 204-207+.  Abstract ( 358 )   Using meperidine abusers as subjects for this study, we detected in hair meperidine and its metabolites normeperidine, N - OCH3 - meperidine and N - AC meperidine. The content of meperidine and normeperidine of 60 abusers were 103 ± 13ong/mg and 117 ± 143ng/mg respectively. Meperidine was stably present in hair for at least 20 months. Normependine level decreased from hair root to tip. The seginental analysis of hair revealed that there were correlations between the drug abuse history andthe distribution of drug along the hair shaft, and betweenthe dose of meperidine and its content presented in hair.

Determination of heroin metabolites in biological fluids,tissues and hair of heroin addicts using GC/MS-SIM XIANG PING;SHEN MIN;WU HEJIAN;ET AL. (INSTITUTE OFFORENSIC SCISNCES;MINISTRY OF JUSTICE;SHANGHAI000;P. R. CHINA) 1999, 0(4): 208-210+.  Abstract ( 264 )   Using GC/MS - SIM, we examined morPhine distribution in human bodies of 2 delayed death cases and analyzed content of morphine and 6 - acetylmorphine (MAM) in hair specimens of 7 cases. Afer hydrolysis and extraction, MoR and 6 - MAM were derived with acetic anhydride or BSTFA and then the derivatives were qualitatively and quantitatively analyzed by GC/MS SIM. The results indicated that urine, bile and liver were the best samples to reveal the heroin - related deaths. Hair analysis has its unique advantage for its long time of abusing monitor, compared to biological fluids. Related Articles | Metrics

Studies on individual characters of juvenile delinquents in Fujian Province LI WEI;LIN JINSHU;CHEN DONGCAI;ET AT (INTERMEDIATECOURT OF NANPING CITY;NANPING 000;P. R. CHINA) 1999, 0(4): 211-213+.  Abstract ( 220 )   Ashenk's Character Questionnaire was adopted tostudy the relationship between juvenile delinquency andindividual characters. 621 delinquents at the age of 13 19 and 1371 school students (as control group) werequestioned, and results were statistically analyzed. Fornlale delinquents of 16 - 19, scores of extroversion,psychosomatic and nervosity were significantly higller thanfor control group (P＜0.01 ). For male delinquents of13 - 15, scores of psychosomatic and nervosity were significantly higher than for control group (P＜0.01 ). Forfemale delinquents of 16 - 19, score of nervosity waslower than for control group (P＜0. 05 ). Different typesof delinquency had no statistical relations with characters.The study reveals that characters of psychosomatic andnervosity might be related with male delinquent crimes,and that stabilization with female delinquent crimes.

CHINA) 1999, 0(4): 216-217+.  Abstract ( 140 )   Forensic pathology materials of 21 cases of cranio cerebral injuries caused by accidental falling were statistically analyzed. The injury causes were discussed. Thecharacteristics of the injuries were investigated and compared with that caused by fa1ling from high, traffic accident and fighting. Related Articles | Metrics

Forensic pathology Analysis of Factors in Causing Trouble by Schizophrenics LIU FANGQI;ZHAO CAIXIA;CHEN QIJIANG;ET AL (QINGDAO INTERMEDIATE PEOPLE'S COURT;QINGDONG 0;P. R. CHINA) 1999, 0(4): 222-223+.  Abstract ( 1985 )   We analyzed the data of different schizophrenics.The data of those who caused trouble were compared tothose who did not cause trouble and to data of othermental patients. It was found that schizophrenics had ahigher rate to cause trouble and commit murder.Schizophrenics who made trouble got worse therapeuticefficacy. They seldom got matried and were not supportedby their fami1y. It is suggest that keeping strict supervision and providing good treatment to schizophrenics bepositive ways to secure our society.
