"법치학적 익사판정에 관한 실험적 연구" : 치수내 익수침투에 관하여

Abstract

[한글]

익수에는 특정지역에 특이한 유기질 또는 광물질이 (현탁액 또는 용액상으로)포함될 수 있다. 따라서, 조류, 규조류, 모래, 진흙 그리고 분해물질까지도 익사의 장소를 지적하는데 사용될 수 있다.

익사체에는 말단폐부종이 있어, 단백질과 익수가 폐순환을 떠나 폐포속으로 들어가게 된다.

Swann의 실험 (deuterium oxide를 추적자로 사용한)은, 익사체에서는 익사의 과정중에 익수가 대순환계를 출입항율 시사하고 있다. 반면, 교살한 토끼를 분쇄규조의 짙은 현탁액이 포함된 익수에 투수한, Crosfill과 Holden의 조사는 이러한 물질들이 페포강내에 존

재함을 보여주었다( 3마리의 토끼중 2마리에서).

이러한 결과로 볼 때, 익사체로서 발견된 시체의 폐포내에 이종의 입자가 있다는 소견은 생시에 투수되었다고 증명하기엔 만족스럽지 못하다.

이러한 문제점을 제거하기 위해 저자는 해부학적 구조가 특이한 개의 치수를 선택하여, 다음의 성적을 얻었다.

1 .실험규조수 내에서 익사시킨 예에서의 치수내 규조립의 분포를 조사하였다.

2. 교살후 규조수 내에 투수한 예에서는 치수내 규조립을 볼 수 없었다.

3. Gentiana Violet용액으로써는 익사판단이 불가능할 정도로 소량의 익수만이 침투됨이 추정된다.

An Experimental Study on the Forensic Odontological Method in Identification of

Death by Drowning - Studies on Intrusion of Water into Pulp Tissue-

Drowning media may contain organic or mineral matter(in suspension or solution)

which are characteristic of a particular locality or source. Thus algae diatoms,

sand,mud, and even dissolved matter, may be used to indicate the palce where

drowning has cooerred.

In drowning there is a terminal pulmonary oedema in which both protein and fluids

leave the pulmonray circulation and enter the alveoli. Swann;s experiment (using

deuterium oxide as a tracer) show that water leaves and enters the circulation

during the drowning process in drowning .

On the other hand, Crosfill and Holden's investigations on rabbits, immersed

after death water containing a dense suspension of crush diatoms, have shown the

presence of these bodies in the alveolar spaces (two our of three rabbits).

In the view of this results, it appears that the finding of foreign particles in

the alveolae of the lung of a body found drowned cannot be regarded as satisfactory

proof that immersion had occurred during life.

So as to get rid of the above problem, the author selected dental pulp tissue of

dog, specially structured anatomically, and obtained the following results.

1. In the case of drowning in water containing a dense sespension of crush

diatoms, the distribution of diatoms in the pulp tissue was studied.

2. In the cases of experimental animals which were strangulated first and then

thrown into water, the distribution of diatoms in the pulp tissue was not observed.

3. It was very hard to determine drowning by Gentiana Violet solution.
