Plasma melatonin concentrations

	NC	NM	HC	HM
Maternal plamsa (melatonin) (pg/ml)	80 ± 13.7	515 ± 106.5 ***	92.9 ± 17.1	800.7 ± 118.1 ***
Fetal plasma (melatonin) (pg/ml)	33.2 ± 4.5	308.1 ± 50.7 ***	57.6 ± 11.8	326.9 ± 51.3 ***

Note: Values are mean ± SEM for the concentration of melatonin in plasma collected on gestational day 20 from NC, NM, HC, and HM dams and fetuses. n = 9–10 per group. 

Abbreviations: ANOVA, analysis of variance; NC, normoxic control; NM, normoxic melatonin; HC, hypoxic control; HM, hypoxic melatonin.
