[Human placental morphology as an index of features of maternal-fetal relationships].

Principle possibilities of the complex evaluation of the mother-fetus exchange were studied by means of morphological investigations of the human placenta in normality, in vesicular mole, late toxicoses, hemolytic disease of newborns and malformations of the fetus. The investigation of the ratio of the villi of different size, deposition of fibrinoid on their surface, the change of the amount of cytotrophoblastic elements, cells of Kaschenko-Hofbauer and the polymerity of the basic substance are of diagnostic value. The authors propose the basal lamina of the placenta to be included into the scheme of the examination of placenta.

[Morphofunctional specialization of tissue components of the mammalian placenta and adaptational value in changes in the rate of their differentiation (evolutionary and clinical aspects)].

It has been shown that in the ontogenesis of human placenta there occur regular changes in the percentage of the villi of various calibre having different interrelationships between the trophoblast, the connective tissue stroma and the fetal vessel. The changes of the number of chorial villi affected by fibrinoid and containing blood vessels under the trophoblast in late toxicoses of women and the anemic syndrom are analyzed (treated and not treated groups of women suffering from different forms of toxicosis were compared). An increased amount of chorial villi having blood vessels under the trophoblast is noted which is a morphofunctional feature of compensatory-adaptational alterations. Possible ecologo-evolutionary approaches to clearing the biological significance of adaptational changes of morphogenesis of the human placenta in pathological pregnancy are shown by the example of the analysis of morphological peculiarities of the placenta of the dolphin.

[Obese patients in obstetrics].

The results of two studies about the course of pregnancy and delivery in adipose women in our hospital are combined and discussed. We found a higher rate of EPH-gestosis in overweight patients. The frequency of Cesarean section was increased. Belated uterine involution post partum is more frequent in adipose women, also the occurrence of urinary tract infections. There is a significant increase in perinatal mortality, mainly due to an increase in still-born. Pneumonia due to aspiration and birth traumata occur more frequently as well and endanger the children.

Respiratory distress syndrome of the newborn and complications of pregnancy.

A group of 412 infants with birthweights between 501 and 2,500 gm and gestational ages of 36 weeks or less were studied for the influence of both prolonged ruputre of amniotic membranes and maternal hypertension on the incidence of idiopathic respiratory distress syndrome (IRDS). The occurrence of these complications was associated with a significant decrease in the incidence of IRDS only in infants with birthweights between 1,501 and 2,500 gm (37.4% in the no complications group versus 12.8% in the complications group; P less than .01) or gestational ages of 33 to 36 weeks (35.2% in the no complications group versus 13.1% in the complications group; P less than .01). In infants with birthweights of 1,500 gm or less or gestational ages of 32 weeks or less, the specific antecedent complications of pregnancy did not alter the incidence of IRDS. Rupture of the membranes for more than 72 hours had no greater effect on the incidence of IRDS than those lasting 24 to 72 hours.

Determination of placental blood flow by external monitoring of 113In.

A simple and noninvasive technique was developed to evaluate the blood perfusion rate within human placenta. The method is based on monitoring the accumulation of the isotope 113mIn in the placental intervillous space using a single detector as a measuring device. The result was expressed as an accumulation index calculated from the tracer appearance curve. The In accumulation index was significantly lower in preeclamptic patients than in the controls, but with a marked overlapping. The In index was significantly correlated with the simultaneously recorded maternal minute volume, 24-hour estrogen excretion and birthweight. No correlation was found with the placental weight or Laakso's perfusion index. Uterine contractions induced a significant decrease in the In index. The authors conclude that the In accumulation index can be used as an objective measure of the placental blood flow.

Cerebral lesions of mature newborn due to perinatal hypoxia. II. Mother's diseases.

The influence of chronic intrapregnancy hypoxia caused by mother's diseases (toxemia, gravidarum, hypochromic anemia, diabetes) on the brain of a mature newborn has been investigated. Besides the vast damages of the parieto-occipital cortex, Ammon's horn (entorhinal) motor and insula cortex there were also some damages of the cerebellum and the brain stem cells. The damages of the cells in the brain stem seem to be one of the causes of the abnormal perinatal adaption.
