摘　　要：本实验用家兔18只,分为溺死组、死后(抛尸)入水组及对照组,每组各6只。采用消化—光镜法作肺、肝、肾硅藻计数(定量)及种属鉴定检验,同时作水样检验及空白对照。结果:(一)进一步证实生前硅藻可经空气源性进入肺脏并存积于大循环内脏(肝、肾)的概念;(二)提示水中尸体肺脏如有大量硅藻检出,仅此即可作为诊断溺死的可靠依据;空气源性吸入及检验过程中的污染并不影响该检验结果对鉴定溺死的判断。种属分析溺死组肺与水样的主要硅藻种属相符,而肝、肾中硅藻计数及种属分析均无诊断意义。Eighteen rabbits were divided into three groups drowning,postmortem submersion and control group. 10g sample was taken from lung,liver and kidney of each rabbit of each group separately.wet-digestion method was used.While the blank control and water sample contol were set. The qualitative and quantitative diatom analysis were carried out as well as by two examiners at the same time.The results indicated as follows:l.Although our study results had proved once again that the air-borne diatomsentered the animals' lungliver and kidn ey before death,actually it had no inf-luence upon the diagnosis of drowning; 2.Death by drowning could be biagnosed,if large anount of diatoms(>the largest value of postmortem submersion and control group)were found in the lung sample The main species of diatoms found in the water sample and drowninga nimals were the same; 3.There was no significant difference of diatom both quantitative and qualitative between postmortem submersion and control group;4. There was no diagnostic value of the diatom analysis for the liver or kidney. A favorable result was obtained in a case of drowning victim of human being submerged in the reservoir for two days examined by the same method,it showed that the conclusionof our study could be used in the forensic medicine practice
