Recent studies show that human placenta, processed and encapsulated for postpartum consumption, contains a host of trace minerals and hormones that could conceivably affect maternal physiology. Our objective was to investigate whether salivary hormone concentrations of women ingesting their own encapsulated placenta during the early postpartum differed from those of women consuming a placebo.
Randomly assigned participants (N=27) were given a supplement containing either their dehydrated and homogenized placenta (n=12), or placebo (n=15). Saliva samples were collected during late pregnancy and early postpartum. Samples of participants' processed placenta, and the encapsulated placebo, were also collected. Hormone analyses were conducted on all samples utilizing liquid chromatography-tandem mass spectrometry.
There were no significant differences in salivary hormone concentrations between the placenta and placebo groups post-supplementation that did not exist pre-supplementation. There were, however, significant dose-response relationships between the concentration of all 15 detected hormones in the placenta capsules and corresponding salivary hormone measures in placenta group participants not seen in the placebo group. The higher salivary concentrations of these hormones in the placenta group reflects the higher concentrations of these hormones in the placenta supplements, compared to the placebo.
Some hormones in encapsulated placenta lead to small but significant differences in hormonal profiles of women taking placenta capsules compared to those taking a placebo, although these dose-response changes were not sufficient to result in significant hormonal differences between groups. Whether modest hormonal changes due to placenta supplementation are associated with therapeutic postpartum effects, however, awaits further investigation.
最近的研究表明,经过处理和封装供产后食用的人类胎盘含有多种痕量矿物质和激素,这些物质可能会影响产妇的生理机能。我们的目的是调查在产后早期食用自身封装胎盘的女性的唾液激素浓度是否与食用安慰剂的女性不同。
随机分配的参与者(N=27)被给予含有脱水和匀浆胎盘的补充剂(n=12)或安慰剂(n=15)。在妊娠晚期和产后早期采集唾液样本。还采集了参与者加工胎盘和封装安慰剂的样本。所有样本均采用液相色谱-串联质谱法进行激素分析。
补充后,胎盘组和安慰剂组的唾液激素浓度没有差异,而补充前存在差异。然而,在胎盘组参与者中,所有 15 种检测到的激素在胎盘胶囊中的浓度与胎盘组参与者的相应唾液激素测量值之间存在显著的剂量反应关系,而在安慰剂组中则没有这种关系。胎盘组中这些激素的唾液浓度较高,反映了胎盘补充剂中这些激素的浓度高于安慰剂。
一些封装在胎盘中的激素导致服用胎盘胶囊的女性的激素谱与服用安慰剂的女性相比出现了微小但显著的差异,尽管这些剂量反应变化不足以导致组间激素差异显著。然而,胎盘补充剂引起的适度激素变化是否与产后治疗效果有关,还需要进一步研究。
