Abstract:With FAAS,contents of three trace elements,Zn,Cu and Fe in the extract of fetus brain were detected,and pared with the same kind of preparations for analy- content of Zn(g・L×10-3 )± they were ±± Cu and contents of Zn and Cu were higher than those of the other4kinds of preparations,and the con-tent of Fe was in the second is suggested that the clinical effect of the extract of fetus brain is better than that of other4preparations.

1 材料和方法

材料胎脑提取液注射液,选用正常妊娠,6mo以内水囊引产的新鲜人胚胎脑组织,由本室制成无色透明注射液封存,每支2mL;Cerebrolysin注射液,奥地利EBEWE制药厂;星工牌脑复康(乙酰胺吡咯烷酮)注射液,沈阳第一制药厂;吉研牌脑复素注射液,吉林省药物研究所制药厂;迪龙牌脑复素注射液,中美合资黑龙江迪龙制药有限公司.

方法使用美国产P-E3030型原子吸收分光光度计,P-E公司产Zn,Cu,(乙炔)和助燃气(空气)・min-1 ,・min-1 (表1).用火焰原子吸收法直接检测以上5种制剂中微量元素Zn,Cu,Fe的含量,,Cu,・L-1 ,国家标准溶液(NCS).工作液Zn,Cu,・L-1 .标准系列(g・L-1 ×10-3 )Zn:,,,,,,;Cu:,,,,,,;Fe:,,,,,,,Cu,Fe的标准系列工作液,以做分析对比,空白实验用水采用去离子水,由仪器计算机系统绘制标准曲线,并计算出回归方程和相关系数.
