The concentration of dopamine (DA), norepinephrine (NE), and its metabolites 3-methoxy-4-hydroxy-phenylethylene glycol (MHPG) and vanillyl mandelic acid (VMA), and prostaglandins E2, and F2a in amniotic fluid were measured at labor (1-3 cm of cervical dilatation), in uncomplicated and complicated pregnancies. The amniotic fluid concentration (mean +/- SD) of MHPG in maternal smoking (S) (30.6 +/- 11.9 nmol.mg creatinine-1) and intrauterine growth retardation (IUGR) (36.7 +/- 15.2 nmol.mg creatinine-1) groups is significantly higher than in uncomplicated pregnancies (C) (22.9 +/- 8.8 nmol.mg creatinine-1), or diabetes mellitus groups (D) (26.1 +/- 10.9 nmol.mg creatinine-1) groups; VMA presents similar differences between groups S (145.8 +/- 84.4 nmol.mg creatinine-1) and IUGR (173.0 +/- 135.4 nmol.mg creatinine-1) higher than C (58.3 +/- 26.1 nmol.mg creatinine-1) and D (76.8 +/- 49.0 nmol.mg creatinine-1) groups. NE levels differ between groups in a similar way, but DA does not present significant differences between groups. Prostaglandin levels are higher in the S than in the C group. Nicotine action and/or hypoxia are proposed as a possible cause of NE, MHPG, and VMA rise in amniotic fluid of S, and IUGR versus C or D groups.

D008734	Methoxyhydroxyphenylglycol	Synthesized from endogenous epinephrine and norepinephrine in vivo. It is found in brain, blood, CSF, and urine, where its concentrations are used to measure catecholamine turnover.

D009638	Norepinephrine	Precursor of epinephrine that is secreted by the ADRENAL MEDULLA and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers, and of the diffuse projection system in the brain that arises from the LOCUS CERULEUS. It is also found in plants and is used pharmacologically as a sympathomimetic.

D011248	Pregnancy Complications	Conditions or pathological processes associated with pregnancy. They can occur during or after pregnancy, and range from minor discomforts to serious diseases that require medical interventions. They include diseases in pregnant females, and pregnancies in females with diseases.

D004298	Dopamine	One of the catecholamine NEUROTRANSMITTERS in the brain. It is derived from TYROSINE and is the precursor to NOREPINEPHRINE and EPINEPHRINE. Dopamine is a major transmitter in the extrapyramidal system of the brain, and important in regulating movement. A family of receptors (RECEPTORS, DOPAMINE) mediate its action.
