Glycogen, glucose, some nucleosides and purine base derivatives were determined in biopsies from 10 term pregnant women undergoing elective cesarean sections before labor. The concentrations were compared in the biopsies which were cut from isthmus and fundus of the uterus and m. rectus abdominis. M. rectus biopsies had 1.5 and 2 times higher concentration of glycogen than the isthmic and fundal uterine biopsies, respectively. The glucose concentration in the striated muscle was on the other hand only half that in the myometrium. The uterus displayed regional differences in concentrations of glycogen (higher in isthmus). A relatively low glycogen content in term pregnant uterine smooth muscle compared with striated muscle signifies the restricted energy demands of pregnant myometrium.
对10名足月孕妇在临产前择期剖宫产时获取的活检组织进行糖原、葡萄糖、一些核苷和嘌呤碱衍生物的检测。比较了取自子宫峡部、子宫底部和腹直肌的活检组织中的浓度。腹直肌活检组织中的糖原浓度分别比子宫峡部和子宫底部活检组织高1.5倍和2倍。另一方面，横纹肌中的葡萄糖浓度仅为子宫肌层的一半。子宫在糖原浓度方面存在区域差异（峡部较高）。足月妊娠子宫平滑肌中的糖原含量相对低于横纹肌，这表明妊娠子宫肌层的能量需求有限。
