产前酒精暴露(PAE)可导致一系列异常,包括大脑和行为功能障碍,统称为胎儿酒精谱系障碍。在第一和第二个三个月期间的PAE是常见的,并且在动物模型中的研究已经记录了在此期间与PAE相关的显著神经发育智力缺陷。然而,关于PAE对胎儿脑血管系统的直接影响知之甚少。在这项研究中,我们使用在子宫内散斑方差光学相干断层扫描,高空间和时间分辨率的成像方式,以评估动态变化的微血管的第二个三个月相当于小鼠胎儿大脑,几分钟后,狂欢样母亲酒精暴露。与假手术组相比,急性暴食样PAE导致血管直径快速(<1小时)和显著(P <0.001)减小。数据显示,在神经发生的关键时期,母亲饮酒过量会导致胎儿脑血管迅速收缩。
Prenatal alcohol exposure (PAE) can result in a range of anomalies including brain and behavioral dysfunctions, collectively termed fetal alcohol spectrum disorder. PAE during the 1st and 2nd trimester is common, and research in animal models has documented significant neural develop mental deficits associated with PAE during this period. However, little is known about the immediate effects of PAE on fetal brain vasculature. In this study, we used in utero speckle variance optical coherence tomography, a high spatial- and temporal-resolution imaging modality, to evaluate dynamic changes in microvasculature of the 2nd trimester equivalent murine fetal brain, minutes after binge-like maternal alcohol exposure. Acute binge-like PAE resulted in a rapid (<1 hour) and significant decrease (P <.001) in vessel diameter as compared to the sham group. The data show that a single binge-like maternal alcohol exposure resulted in swift vasoconstriction in fetal brain vessels during the critical period of neurogenesis.
