Peripheral circulating E-rosette-forming cells subpopulations (high affinity and low affinity E--RFC) were studied in pregnant women. In prelabor the high affinity/low affinity E--RFC ratio was found to decrease as compared with the controls by the decrease of the high affinity E--RFC (mean +/- SD, 33.4 +/- 15.9%, p less than 0.01) and the increase of the low affinity E--RFC percentage (mean +/- SD, 37.0 +/- 11.8%, p less than 0.001). As compared with prelabor the low affinity E--RFC subpopulation decreased during normal labor (mean +/- SD, 14.1 +/- 6.2%, p less than 0.001) and not in abnormal labor. These changes might be implicated in the final "fetal allograft rejection" and are probably due to some serum factors in pregnancy.
In two groups of women--one group of 12 normal-mammary-gland controls and another group of 10 idiopathic galactorrhoea patients--we determined the blood concentration of serotonin and prolactin. The obtained data show no significant differences between the studied groups either in serotonin or prolactin levels i.e., serotonin is not implied in the pathogeny of idiopathic galactorrhoea. The data are confirming our previous results concerning the functional correlations between the serotonin system and prolactin release, as well as the data obtained by other authors on the normal values of prolactin in idiopathic galactorrhoea.

A high proportion of parainfluenza, herpes, adenovirus and chlamydial antigens (10.7-36%) was detected by indirect immunofluorescence in cells exfoliated in the vagina of women with genital neoplasia and with uterine cervix ectopia and dysplasia. Much lower proportions of the same antigens were found in patients with common gynecopathies or recurrent genital herpes and in pregnant women. The possible relationships between chronic virus infections and genital neoplasia in women are discussed.
