心房肽是近年从心房肌中提取的一类多肽。放射免疫研究证明肺内含有心房肽样物质,为了了解其在肺内的存在位置和分布特点,本文用辣根过氧化物酶-抗辣根过氧化物酶(PAP)免疫组织化学方法,观察了大白鼠肺。肺组织经4％多聚甲醛固定,冲洗和脱水后,常规石蜡包埋。切片厚6μm。抗 Atrial peptide is a kind of polypeptide extracted from atrial muscle in recent years. Radioimmunoassay studies have shown that the pulmonary atrial peptide-like substances, in order to understand its location and distribution in the lungs of the characteristics of horseradish peroxidase - anti-horseradish peroxidase (PAP) immunohistochemical method to observe Rat’s lungs Lung tissue was fixed with 4% paraformaldehyde, rinsed and dehydrated and embedded in paraffin. Slice thickness 6μm. anti-
