We observed significant changes in both copper plasma concentrations and zinc plasma
concentrations during the four times studied (p < 0.05).
在研究的四次中，我們觀察到銅血漿濃度和鋅血漿濃度的顯著變化（p <0.05）。
The changes of Cu during the various phases correlated negatively with the changes in E2
(r > 0.5, p < 0.05), whereas the changes of Zn correlated positively with those of E2
(r > 0.8, p < 0.05).
不同階段Cu(銅)的變化與E2的變化呈負相關（r> 0.5，p <0.05），
而Zn(鋅)的變化與E2的變化呈正相關（r> 0.8，p <0.05）。
催乳素（Prolactin，簡稱PRL，又叫促乳素或催乳激素）
是一種由垂體前葉腺嗜酸細胞分泌的蛋白質激素。主要作用為促進乳腺發育生長，刺激並維持泌乳。
Low calcium inhibited prolactin secretion by 40-60%.
低鈣抑制催乳素分泌40-60％。
Calcium specifically stimulates prolactin synthesis and messenger RNA sequences in GH3 cells.
鈣特異性刺激GH3細胞中的催乳素合成和信使RNA序列。
manganese (Mn) has been shown to increase prolactin (PRL)
by decreasing dopamine (DA) in the hypothalamus
錳（Mn）已被證明可通過降低下丘腦中的多巴胺（DA）來增加催乳素（PRL）
These all represent potential regulators of prolactin expression, synthesis,
and release and, as such, may be affected by Zn deficiency.
這些都代表了催乳素表達，合成和釋放的潛在調節劑，因此可能受到鋅缺乏的影響。
Progesterone upregulates prolactin synthesis
孕酮上調催乳素合成
The effect of vitamin A supplementation on plasma estrogen and progesterone
were studied in pregnant women. While there was no change in the estrogen concentration,
the mean increment in plasma progesterone in the supplemented group was significant when
compared to the unsupplemented group. It is suggested that vitamin A supplementation
to undernourished pregnant women may have beneficial effect on feto-placental function.
研究了孕婦補充維生素A對血漿雌激素和孕酮的影響。 雖然雌激素濃度沒有變化，
但與未補充組相比，補充組中血漿孕酮的平均增量是顯著的。
補充維生素A可能對胎兒胎盤功能有益。
