溺死家兔内脏花粉检验的研究

用醋酸酥法破机，显微镜下观察内脏组织中花粉。12只溺死家兔的肺边缘组织检出率为100％（肺组织含花粉500粒／g左右），肝为50％，肾为33．3％；溺死后1天，1周、2周三组解剖，肺边缘组织花粉计数值无明显差异，证明花粉具有很强的抗腐败能力，可以作为水中高度腐败尸体死因鉴定依据之一。同时，水体沉积物花粉港能够反映入水地点的植被状况，为判断和认定溺死者的入水地点提供依据；此法尤其适用于冰水等硅藻和浮游生物很少的水体中的生前入水溺死的诊断。

AN EXPERIMENTAL STUDY OF DETECTING POLLEN FROM THE RABBIT'S ORGANS DIED OF DROWNING

This paper presents that the pollen in the rabbit's organs died of drowning detected by themethod of acetic anhydride destroying organic tissues method. of the 12 rabbits, the pollens werefound in the periphery pulmonary tissues of all the rabbits, in livers of six rabbits and kidneys of four.There are no significant difference of pollen amount and ratio of pollen species in lungs between threegroups examined one day, one and two weeks respcetively after drawing. It is suggested that thepollen has the characteristic of anti-decomposition. So, pollen is a reliable evidence of diagnosis of thedrowning,Besides, the vegetation condition in local area can be reflected by the pollen in sediment inwater. Therefore, this study may provide evidences to estimate the place where the drown body fallsinto the water. This method is specially applicable to diagnose drowing in the water with little diatomand other plankton.
