慢性支气管炎150例用胎盘多肽治疗,用量2mL(胎盘组织提取物3g)im,bid×10d,乃2mL,qd×20d,再2mL,qod×15d,加常规药物(青霉素80万U,链霉素0.5g, im, bid×45d,镇咳药);70例接受胎盘多肽,40例用常规药物。结果总有效率3组分别为84％,64％和55％,3组细胞免疫指标上升率分别为62％,50％,40％,提示胎盘多肽能改善其细胞免疫功能。 150 cases of chronic bronchitis treated with placental peptide, the amount of 2mL (placental tissue extract 3g) im, bid × 10d, is 2mL, qd × 20d, then 2mL, qod × 15d, add conventional drugs (penicillin 800,000 U, Prime 0.5g, im, bid × 45d, antitussive); 70 cases of placental peptides accepted, 40 cases with conventional drugs. Results The total effective rate was 84%, 64% and 55% respectively in three groups. The rising rates of cellular immunity in three groups were 62%, 50% and 40% respectively, suggesting that placental peptides could improve their cellular immune function.
