摘　　要：选用脑死亡2～4小时后成年男性(20～40岁)新鲜心脏的三尖瓣瓣叶、腱索和乳头肌标本各20例,用生物化学方法测定了瓣叶、腱索、乳头肌尖部和乳头肌基部内羟脯氨酸(hydroxyprolin,HX)和氨基已糖(aminohexose,AH)的含量(μg/100mg组织),结果依次为1435.00±138.46和1670.33±358.39.2156.26±309.38和2156.26±309.38和1324.16±428.37、543.25±115.94和1267.50±105.23、347.50±80.48和1238.00±202.71.上述各部内HP的含量比值依次为1:1.50:0.39:0.24;AH为1:0.79:0.76:0.74.HP在腱索内含量最高,瓣叶内次之,乳头肌内最低.AH在瓣叶内含量最高.结果提示腱索和瓣叶是富含HP和AH的组织,这与形态学上观察到的腱索和瓣叶内胶原纤维密集的结果相符.此结果为进一步研究瓣膜装置的生化成分和对心瓣膜疾病的诊断、治疗提供参考资料.The content of hydroxyproline and aminohexose in 20 fresh tricuspid apparatus (valvular leaf, chorda tendinea and papillary muscle) was determinated by biochemical method. The average content (ug/100mg tissue) of hydroxyproline and aminohexose in the valvular leaf, chorda tendinea, and top and basic part of papillary muscle is 1435.00 and 1670.33, 2156.26 and 1324.16, 543.25 and 1267.50, and 347.50 and 1238.00 respectively. The results provide the reference for the study of biochemical composition of the tricuspid apparatus and for the diagnosis and treatment of valvalar disecases.
