作者测定了168名正常人(男95名,女73名)的血浆纤维结合蛋白(Fn)、转铁蛋白(TRF)及其它非特异性调理素(C_3、C_4、备解素)的含量。按年龄分为三组:青年组,16～29岁,57名;成人组,30～59岁,71名;老年组,60岁及以上者,40名。年龄增长,血浆Fn相应增加;TRF呈下降趋势。年龄对其它非特异性调理素无多大影响。性别对血浆Fn和TRF的含量无明显作用,只是在老年组中TRF在不同性别中有差异性,随年龄增长,血浆Fn和TRF呈负性相关。
The authors determined the levels of plasma Fibronectin (Fn), transferrin (TRF) and other non-specific opsonins (C_3, C_4, properdin) in 168 normal subjects (95 males and 73 females). Divided into three groups according to age: youth group, 16-29 years old, 57; adult group, 30 to 59 years old, 71; elderly group, aged 60 and over, 40. With age, plasma Fn increased accordingly; TRF decreased. Age has little effect on other nonspecific opsons. Gender had no significant effect on plasma levels of Fn and TRF, except that the TRF differed in different genders in the elderly group. The plasma levels of Fn and TRF were negatively correlated with age.
