The solubility of collagen of the uterine cervix during pregnancy and labour.

The solubility of collagen during pregnancy and labour was studied in tissue specimens of the uterine cervix of 48 women in childbearing age. In the course of pregnancy the fractions of collagen which are soluble in 0.175 M acetic acid at +5 degrees C and in 8 M urea at +40 degrees C increased continuously in relation to the total collagen content and dry weight.

[The risk of yeast infection, of the newborn during and after delivery (author's transl)].

The importance of yeast infections in obstetrics was investigated in 200 pregnant women and their newborns. In the maternity patients the vagina was tested shortly before the delivery and the mouth of the neonates was tested 1 day prior to the discharge from the hospital. In 22% of the pregnant women and in 8,4% of the newborns, yeast (predominantly candida albicans) was found in the culture.
