摘要： <正> 亚硝酸盐中毒尸体血中含量测定,经我们检案及动物实验证明:福尔马林固定血比未固定血中检出时限明显延长.但在得不到固定血的情况下,福尔马林固定脏器中能否检出亚硝酸盐?其检出时限与未固定脏器有无差异?我们对亚硝酸钠中毒死亡动物的肝脏及肾脏进行了亚硝酸含量测定.

Abstract: The nitrite conservation time of formalin fixed liver and kidney were investigated. 40 male rats had been divided into 4 groups with nitrite oral doses of 110(LD50),220 (LD) and 450 (over LD100) mg/kg respectively.Each rat liver and kidney(the survivors were sacrificed) was divided into two parts: formalin fixed and non-formalin fixed.As a result, the conservation time was prolonged remarkablely in the formalin fixed part.Nitrites could be detected as long as three months in all administrated groups while in non-formalin fixed part, 20 days at the longest (450 mg/kg group) .It shows a great adventage in the work of identification in the field of forensic medicine as it is ordinary to get the samples of cases fixed with formalin.
