    Notes: Platelets were isolated from menstrual and peripheral venous blood samples taken from nine women during the first 2 days of menstruation. The washed platelets were tested for their ability to aggregate in response to arachidonic acid, ADP, and collagen, and to metabolize arachidonic acid. Menstrual platelets differed from venous platelets in (1) failing to aggregate when challenged with aggregatory stimuli and (2) producing no appreciable cyclo-oxygenase products from arachidonic acid as reflected in thromboxane B2 release. However, incubation of peripheral venous platelets with menstrual serum obtained from the same patients induced aggregation. The responses of menstrual and peripheral venous platelets were the same irrespective of the patients’ total menstrual blood loss. Uterine venous platelets collected during menstruation from two patients at hysterectomy aggregated normally and produced thromboxane B2.

    Notes: Peripheral plasma levels of 13,14-dihydro-15-keto-prostaglandin F (PGFM) were determined in women during pregnancy and in term and preterm labour. The PGFM concentrations at term were not significantly different from the levels between 26 and 34 weeks gestation. In both term and preterm labour there was a rise in PGFM levels with increasing cervical dilatation although the mean values tended to be lower during preterm labour. These findings may provide an explanation for the effectiveness of prostaglandin synthetase inhibitors in suppressing myometrial activity in preterm labour.

    Notes: Concentrations of 6–keto–prostaglandin F1α (6–keto–PGF1α, the stable metabolite of prostacyclin, PGI2) have been measured in amniotic fluid obtained during late pregnancy and labour. Samples taken at amniotomy during spontaneous labour contained a significantly greater concentration of 6–keto–PGF1α than samples taken at amniotomy before the onset of labour (p 〈0.01). There was no correlation between the level of 6–keto–PGF1α, in amniotic fluid before labour and gestational age (p 〉 0 1). It is suggested that prostacyclin may have a functional role in the mechanism of parturition in man.

    Notes: The labour, delivery and state of the newborn were compared retrospectively in a group of women who had labour induced and a group who started labour spontaneously. There were 200 women at term in each group, individually matched for age, parity and social class and with no medical or obstetric complications prior to labour. The induced group showed a higher incidence of epidural anaesthesia, fetal monitoring and operative delivery. Sixty had forceps deliveries and five had Caesarean sections compared with two forceps deliveries and no Caesarean sections in the ‘spontaneous onset’ group. The higher incidence of operative deliveries in the induced group was not fully explained by the excess of epidurals and fetal monitoring received. More of the babies born after an induced labour had endotracheal intubation during resuscitation.

    Notes: Peripheral plasma levels of oxytocin were determined in women during pregnancy and labour. There was a significant increase in maternal plasma oxytocin with advancing gestation but no significant change in levels at any stage of labour. Oxytocin concentrations in umbilical cord plasma were measured after spontaneous vaginal delivery and at elective caesarean section. A significant arteriovenous difference, with higher arterial levels, was found in both groups and the values after labour were significantly higher than at elective caesarean section. These findings suggest that the fetus is able to produce oxytocin which may play a role in human parturition.

    Notes: In women with menorrhagia of unknown cause, the efficacy of the drug danazol in reducing heavy menstrual blood loss was investigated making objective measurements of menstrual blood loss. Drug regimens tested were daily administration of 200 or 100 mg danazol for 12 weeks and daily danazol given in the luteal phase or during menstruation. The results suggest that 200 mg danazol daily is the most acceptable regimen clinically since it significantly reduced menstrual blood loss and was associated with a relatively low incidence of side effects. In 16 women on this dose menstrual blood loss was suppressed from a mean pre-treatment loss of 183±25ml to 38±11 ml (p〈0.01) in the second, and 26±9 ml (p〈0.01)in the third treatment months. The majority of women had regular episodes of bleeding with no alteration in cycle length and a reduction in the number of days of bleeding. Although 100 mg daily suppressed menstrual blood loss, particularly by the third month of treatment, it increased the number of episodes of bleeding in some women which they found unacceptable. Both 200 mg and 100 mg relieved dysmenorrhoea in the majority of women presenting with the symptoms. Danazol taken daily in the early follicular or luteal phase of the menstrual cycle did not significantly alter menstrual blood loss. There was no effect of placebo therapy on measured menstrual blood loss in a single blind trial in eight women with menorrhagia.

    Notes: In women having either cervical encerclage under general anaesthesia or a vaginal examination in the early second trimester of pregnancy, peripheral plasma levels of 13,14-dihydro-l5-keto prostaglandin F (PGFM) were measured before and after each procedure. A significant rise in circulating levels of PGFM was found within minutes of completing cervical encerclage but not after vaginal examination or induction of general anaesthesia.

    Notes: The concentration of melatonin in maternal peripheral plasma was measured during late pregnancy, term and pre-term labour. There was a small increase in the mean concentration of melatonin during labour which was significant in term labour. Umbilical arterial and venous plasma, whether obtained at term, after spontaneous vaginal delivery or at Caesarean section, contained significantly greater concentrations of melatonin than maternal plasma. A significant arterio-venous difference was demonstrated for both groups of umbilical samples with raised venous levels after spontaneous vaginal delivery but higher arterial levels at Caesarean section.

    Notes: Eighteen patients with objective evidence of menorrhagia (more than 80 ml menstrual blood loss) were treated with danazol for twelve weeks. Danazol significantly reduced the menstrual blood loss from 231±39 ml (mean±SEM) to 135±33 ml in the first treatment month and the mean loss thereafter was only 21 ml and 3 ml for the second and third months respectively. A rapid increase in haemoglobin level and a reduction in the number of days of bleeding were also observed on danazol treatment. No important effect on the coagulation profile was observed during the period of study. Three months after stopping danazol, menstrual blood loss (103±27 ml) was still significantly less than the pre-treatment loss.

    Notes: Concentrations of melatonin have been measured in amniotic fluid obtained during late pregnancy and labour. Samples obtained by amniotomy during labour contained higher concentrations of melatonin than samples taken a t amniotomy for the induction of labour. Amniotic fluid obtained by amniocentesis in late pregnancy contained lower concentrations of melatonin than amniotic fluid obtained by amniotomy. The implications of these findings are discussed in relation to pineal influences on parturition.
