Abstract
Spermidine (SPD) and spermine (SP) concentrations and the activities of ODC and SAT have been measured in retina and lens of the rats maintained in 60% atmospheric oxygen for the first 14 days life. Hyperoxia, known to cause retardation of vessel growth, was associated with some reduction of the enzyme activities and polyamine levels.
摘要
在出生后前14天饲养于60%大气氧环境中的大鼠的视网膜和晶状体中，已测定了亚精胺（SPD）和精胺（SP）的浓度以及鸟氨酸脱羧酶（ODC）和精氨酸琥珀酸合成酶（SAT）的活性。已知高氧会导致血管生长迟缓，它与酶活性和多胺水平的某些降低有关。
