Part One: Biomechanics of Skull Injury Caused by Blunt Weapons ZHENG LANSHI;ZHANG PENG INSTITUTE OF FORENSIC SCIENCES. MINISTRY OF JUSTICE;PRC 1988, 0(2): 1-11+1.  Abstract ( 1893 )   The auther has made a theoretical study of skull injury caused by blunt weapons which falls within the scope of forensic science, from the standpo- int of biomechanics, and has also carried ont relevant experiments. Discuss- ion has been made about the mechanism of various types of skull injury by applying the theory of shells. The transmission of the momentum and the effect of the neck cushion during the process when the blow is dealt have also been analysed. Experiments show that the shapes of injury vary with the transmission of the impact of the blow and the force of the blow relati- ve to time. Higher peak striking force and shorter time lasting appeared to the brittal skulls, and otherwise to the tenacious ones. Related Articles | Metrics

Part Two: Morphologic Study of Skull Injury caused by Blunt Weaqons ZHENG LANSHI;ZHANG PENG INSTITUTE OF FORENSIC SCIENCES. MINISTRY OF JUSTICE;PRC 1988, 0(2): 11-14.  Abstract ( 1958 )   Two groups of cadaver skulls were struck with a hammer and a club respectively, Various types of skull injuries were yielded. The experiments showed the relationship between the festures of the skull injuries and the shapes of the weapon used and also the manners in which they were applied to the skulls. We also found that: the most prominent and the widest part of the linear fracture is not certainly the point of impach the separation of cranial suture relates not only with the striking force but also with the pattern and extent of the suture closure; the hammer with a circular face can cause an oval perforated fracture.

The Astimation of Tooth Age on the Different Age grougs in the Use of Tooth Attritions SONG HONGWEI;JIA JINGTAO DEPARTMENT OF FORENSICMEDICINE;CHINA MEDICAL UNIVERSITY;SHENYANG 1988, 0(2): 15-20.  Abstract ( 3336 )   The data of this paper was gathered from 880 cases in Liaoning province in China. By applying the Theory of Quantification Type I and the Multiple Stepwise Regression the mathematic models were established to estimate age on the basis of the tooth attrition-degree, and the equations on the estimation age of different age groups have been obtained by the aid of computer tech- nique as well. These equations, for the convenience of usage, have been turned into the tables on estimation of age. The correlation coefficients (R) are from 0. 61 to 0. 83. The test-significance of variance analysis is of greet sig- nificance (F>F0. 01). The errors of the estimated age with the real age is as follows; 57. 3-96. 3% in ± 3 years error, 77. 3-100% in ±5 years error. Related Articles | Metrics

Assay of PGM_1 And EsD In The Dead Foetus HE GENLAN;XU JUNJIE 1988, 0(2): 21-23.  Abstract ( 1960 )   PGM_1 and EsD was assaied by the starch-agarose gel eleetrophoretic method. Different tissues of the foetus had a same PGM1 and EsD polymorphism. In the rotten foetus we obtained same polymorphism from skeletal muscle, central blood and brain. Related Articles | Metrics

Investigation of Esterase D (EsD) Phenotype Frequencies in the Han Nationalities Shichuan, China CHEN GUODI;TAN MING;CAO ZHIMIN;MAO YONGQIU DEPARTMANT OF FORENSIC SEROLOGY WEST CHINA VNIVERSITY OF MEDICAL SCIENCEE 1988, 0(2): 24-25+2.  Abstract ( 1977 )   Investigation on the distribution of erythrocyte esteraes D of 555 Chiness rendom blood donors, Hah nationalities in Shichuan, China. is reported. The phenotype frequncies were: EsD1-1=35. 50%, EsD2-1=52. 61%, EsD2-2= 11. 89%. Their gene frequncies were: EsD~1=0. 6810, EsD~2=0. 3820. Related Articles | Metrics

Forensic-Toxicological Studies on Chinese Crude Drug Yang-Jin-Hua (Datura) Ⅱ. An Investigation on Acute Toxicity ZHAO TAIAN;ZHENG ZHONGXUAN;BU JUN;SHEN YAN INSTITUTE OF FORENSIC SCIENCES;MINISTRY OF JUSTICE. PRC 1988, 0(2): 26-28.  Abstract ( 2053 )   There are some data on acute toxity of Yang-Jin·Hua (Datura), but they are Very rough and ambigurous. In this paper, an acute toxity of Yang-Jin- Huan was reported. Exstracts from its flower, fruit and seed were experimen- ed on 180 rats. The results showed fhat the LD50 of exstracts from flower. fruit and seed were 14. 9314, 7. 7625 and 7. 1746 g/kg respectively, The toxici- ty of Yang-Jin-Hua was very high and the toxity of its flower was lower than that of its fruit and seed. The alkaloids in flower, though it was a little strange, were much more than that in fruit and seed. The reason of it was not clear. Related Articles | Metrics

Experimental Study on Detection Methods of Phosacetim in Intoxicant Death Ⅱ. Qualitative and Quantitative Analysis of Phosacetim in Biological Samples SHEN MIN;WU MOUTIAN;BU JUN DEPARTMENT OF FORENSIC CHEMISTRY;INSTITUTE OF FORENSIC SCIENCES;MINISTRY OF JUSTICE;PRC 1988, 0(2): 29-33+4.  Abstract ( 1864 )   This paper describes the methods for qualitative and quantitative analys- is of phosacetim in biological samples by TLC, TLCS and HPLC. The methods given are quick, reproducible and linear with correlation coefficient of TLC and HPLC was 0. 996. The presence of interfering components, as are com- monly found in postmortem, did not affect the result. For these reasons, the methods were well suited for the analysis of phosacetim in the forensic laboratory. Related Articles | Metrics
