The peak acid output of the stomach in a group of 71 mothers of spina bifida children and in 71 matched controls was estimated indirectly by the serum level of group I pepsinogens. The mean levels did not differ significantly, suggesting that the conjectured teratogen is not specially acid-labile. The variance was significantly higher in index subjects than in controls, but the interpretation of this finding is not clear.
通过I组胃蛋白酶原的血清水平间接估计了71名脊柱裂患儿母亲和71名匹配对照者的胃最大酸分泌量。平均水平没有显著差异,这表明推测的致畸原并非特别酸不稳定。研究对象的方差显著高于对照组,但这一发现的解释尚不清楚。
