青壮年猝死综合征心肌心钠素免疫组化研究

研究青壮年猝死综合征病理形态学诊断依据。应用免疫组化LSAB,观察10例SMDS及10例非心性死亡对照组死者ANP变化情况。结果发现,SMDS中7例ANP呈阴性,3例呈弱阳性;10例非心性死亡ANP呈强阳性。研究表明,SMDS死者心房内ANP数量减少是导致死亡的重要因素,可通过ANP免疫组化观察找到SMDS死亡的形态学依据。

Immunohistochemical study on ANP in the atria of sudden manhood death syndrome

For the purpose of diagnosis of sudden manhood death syndrome, immu- nohistochemical study of ANP was performed in right atria of 10 cases of sudden manhood death syndrome (SMDS) and 10 cases of noncardiac death controls with LSAB-method. It was found that the ANP granulus in right atria of SMDS were obviously depleted, compared with that in the control groups. The results showed that depletion of ANP granules in atria plays an important role in the causes of death of SMDS. This experiment also provides a new approach for studying the causes of SMDS.
