异构前列腺素最主要的成分是８表氧前列腺素Ｆ２α（８表氧ＰＧＦ２α）。有报道肝肾综合征与２型糖尿病患者血浆８表氧ＰＧＦ２α水平明显增高［１］。国外均用气相色谱质谱测定异构前列腺素Ｆ２α，临床推广应用受到限制。为此，我们建立了１２５Ｉ标记的８ The most important component of heterogeneous prostaglandins is 8  Oxygen prostaglandin F2α (8  Oxygen-PGF2α). It has been reported in patients with hepatorenal syndrome and type 2 diabetes plasma 8 Oxygen-PGF2α levels were significantly increased [1]. Foreign countries are using GC-MS determination of isofos prostaglandin F2α, clinical application is limited. To this end, we have established a 125I labeled 8 
