“…The findings of Wolfrum [12] that low urine estriol values are due to a lowered renal clearance or to a lowered estrogen pro duction through impaired fetal-placental function support this hypothesis.…”

The diagnostic value of estriol determinations in high-risk pregnancies is frequently discussed in the literature. Estriol levels of urine and serum samples of 48 asymptomatic pregnant women were analyzed using direct radioimmunoassay. A correlation was found (r = 0.5997) between urine and serum samples, nevertheless the correlation was stronger (r = 0.8278) if 4 cases with extreme deviation were omitted. In these cases the serum estriol levels were high and the urine estriol levels were low. The outcome of the pregnancies was without any complication. Our observations suggest that determination of unconjugated serum estriol levels is more reliable in the monitoring of high-risk pregnancies, since they do not depend on renal and hepatic functions.

“…Therefore, urinary excretion of 6-sulfatoxymelatonin (aMT6s), the major urinary metabolite of melatonin, NE and E 3 were measured in the study. It is already known that the urinary concentrations of aMT6s, NE and E 3 correlate well with their respective serum levels 5,15,16) . Here assessed was the physiological effect of shift work including night work on the health of pregnant women, with special reference to biological functions, which has not been studied in detail.…”

It has been suggested that shift work, night work in particular, affects worker's psychophysical health. However, the effects of night work on the health of pregnant women are not physiologically well elucidated. The effects of night work on the biological function of pregnant women were studied in the present study. Three pregnant and six non-pregnant nurses that engaged in fastrotating shift system cooperated for the study. The 24-h urine samples were collected in two time frames, daytime (07:00 to 23:00) and nighttime (23:00 to 07:00) on the day shift, the night shift and the days off. Urinary concentrations of 6-sulfatoxymelatonin and norepinephrine were measured by enzyme-linked immunosorbent assay and estriol by radioimmunoassay. The excretion profiles of urinary 6-sulfatoxymelatonin in the pregnant and the non-pregnant women were altered on the night shift, which might relate the derangement of circadian rhythm of melatonin secretion. The urinary norepinephrine level during the night work was considerably higher in the pregnant women, which indicated the presence of higher physical burden in them due to the night work. The urinary estriol level was not significantly affected by shift, day/night and individual factors, and the effect of night work on urinary estriol level of the pregnant women remained uncertain. The results of the present study suggested that the night work of the pregnant shift workers should be much more relieved.
