Abstract

In this study, the transfer of odorants, namely vanilla, and garlic, into the amniotic fluid (AF) during the second trimester was investigated by examination of collected AF samples through healthy adults. Eleven AF samples were collected from pregnant women (aged 32.9 ± 4.9 yr, 16-25 wk of gestation) undergoing diagnostic amniocentesis after eating garlic oil or vanilla powder in high-fat yogurt. The control group did not receive food before amniocentesis. Two vanilla, 3 garlic, and 6 control samples were collected through amniocentesis 60-120 min after ingestion. Samples were collected at -80 °C and carefully defrosted over 12 h at the same time point. Sixteen healthy volunteers (8 males, aged 26.5 ± 5.0 yr) were asked to judge AF samples with potential garlic or vanilla odors from controls in a 2-alternative forced choice (2AFC) paradigm. Judges were able to identify vanilla in the AF samples with an estimated probability of 50%, resulting in a significant P-value of < 0.001. In contrast, the identification of garlic was unsuccessful with a P-value of 0.86, and only 2 judges were able to identify both vanilla and garlic. According to the results of this study, the vanilla odor probably passes into the amniotic fluid.

用成人的鼻子闻羊水中母亲的饮食。
在这项研究中,我们通过检查收集到的健康成人羊水样本,对气味物质(即香草和大蒜)在妊娠后三个月转移到羊水(AF)中的情况进行了调查。研究人员采集了 11 份羊水样本,这些样本来自接受诊断性羊膜穿刺术的孕妇(年龄为 32.9±4.9 岁,妊娠期为 16 至 25 周),她们在食用大蒜油或高脂酸奶中的香草粉后进行羊水穿刺。对照组在羊膜腔穿刺前没有进食。在进食 60 至 120 分钟后,通过羊膜腔穿刺术采集了两份香草样本、三份大蒜样本和六份对照样本。样本在-80°C下采集,并在同一时间点仔细解冻十二小时。16 名健康志愿者(8 名男性,年龄为 26.5±5.0 岁)被要求在双项强迫选择(2AFC)范式中对具有潜在大蒜或香草气味的 AF 样品与对照组进行判断。判断者能够识别出房颤样本中香草气味的概率估计为 50%,其显著性 p 值为
