用乙醇和正丁醇判断豚鼠溺死时间的实验探索

ALCOHOL AND N-BUTANOL AS A POSSIBLE INDICATOR OF DROWNED POSTMORTEM INTERVAL

本文以豚鼠为实验动物，溺死后浸泡于水温为２０℃的水缸小。运用气相色谱法测定其溺死后不同浸泡时间在心、肺、肝小＃在的乙醇和正了醇含量。实验结果表明在溺死后８天内，样本中乙醇和正了醇量随浸泡时间的延长而增加，且呈高度的直线相关。其血、肺、矸中乙醇量与溺死时间的回归方程依次为ｙ１＝－１６．８２＋１２．９５Ｘ，ｙ２＝－５８．５３＋１９．２３Ｘ，ｙ３＝－３１．９１＋４７．２９Ｘ。血、肺、肝小正丁醇量与溺死时间的回归方程依次为ｙ４＝－１０．１３＋５．８６ｘ，ｙ５＝－２９．４５＋１６．１７ｘ，ｙ６＝３．７５＋１４．３１ｘ。综合分析溺死后血、肺、肝小乙醇和正丁醇，有可能作为判断溺死时间的新指标。

Alcohol and n-butanol appear in large quantity in blood and organs of a drowned animal or person. Experiment of laboratory animals was proved the existence of a high positive correlation between quantity of alcohol and n-butanol in tissues and the time since drowned death within & days. As a result, the linear regressive equations of alcohol in blood, lung and liver and time of death submerged in water were respectively as follows: Y1=- 16. 82 + 12. 95X,Y2=- 58. 53+ 19. 23X, Y3=- 34. 91 + 47. 29X. The regressive formulas of n-butanol in bind, inns and liver and time of drowned death were respectively aS follows: Y4=- 10. 13+ 5. 86X, Y5=- 29. 15 + 16. 17X,Y6 = 3. 75 + 1 4. 3 1 X. Combining the analysis of quantity of alcohol and n- butanol will become a possible new indiCator of drowned postmortem interval.
