objective:to discuss the significance of the amniotic fluid isoamylase (afi) in detecting the fetus organ maturity by separating and detecting it.
目的:通过羊水淀粉酶同工酶的分离测定探讨其在判断胎儿成熟度中的意义。
the original bacteria ydf30 producing acidic isoamylase was isolated from the soil, after uv and des mutagenetic treatments, a high-yielding mutant hy19 was obtained from a lot of mutants.
以土壤中筛选得到的产异淀粉酶的细菌ydf30为出发菌株,进行了紫外线和硫酸二乙酯复合诱变处理。
conclusion: the activities of serum amylase and isoamylase reflect the severity of pancreatic edema in acute edematous pancreatitis.
