In a modified technique of the cysto-urethropexy the elevation of the vesicle neck is accomplished by suturing the vaginal fascia to the obturator fascia and the internal obturator muscle. In 10 recently deceased female corpses the tensibility of the internal obturator muscle was tested in conditions similar to the modified marshall marchetti krantz technique. The tensibility of the fixation point to the point of tearing out of the suture is in the mean on each side short of 7 Kp. It can be assumed that the tensibility at the fixation point is increased by the contractility of the internal obturator muscle, which among other functions helps to fix the pelvis in the erect body position. In 7 formalin fixed and 3 non-fixed female corpses the thickness of the internal obturator muscle between the fascia and the obturator membrane was measured. In correct operative technique the obturator membrane is not incorporated into the suture since the thickness of the muscle is approximately 7.5 mm. The vessels and nerves in the obturator canal or not touched by the suture as long as the sutures are placed in the medial portion of the muscle. Variations of the arterial blood supply are mentioned.

Lymphocytes in the endometrium were counted during infancy, the reproductive age including pregnancy and the postmenopausal era and in various pathological states (cystic-glandular hyperplasia, adenomatous hyperplasia, endometrial polyposis, endometrium after long-standing ingestion of oral contraceptives, endometrial carcinoma). Compared with the child-bearing era, the lymphocyte concentrations in endometrium were markedly lower during infancy and after the menopause. Lymphocyte concentrations were high in cystic-glandular hyperplasia, endometrial carcinoma and pregnancy, and low in focal adenomatous hyperplasia and endometrial polyposis. Although histological examination of the endometrium after long-standing ingestion of oral contraceptives showed atrophy, the lymphocyte count was high.

The pathomorphological findings in the placentae of diabetic pregnant women were studied in 12 cases of maternal diabetes. The vascularization quotient of the placental villi (VQ) is defined as the surface area of the cut across the villus divided by the surface area of the capillaries within the villus. The vascularization quotient of the diabetic mothers was compared with control placentas of healthy maternity patients. It was found that in normal placentas about half of the surface of the villus is taken up by the surface of capillaries (VQ = 0.44). In diabetics about 1/4 of the villus surface is taken up by capillary surface (VQ = 0.23). The villi of diabetic placentas showed in general fewer capillaries in larger villi. These changes were more marked if normo-glycaemia was obtained late in pregnancy by the administration of insulin. The findings were in no correlation to Whites classification of the pregnancy which measures factors which are independent of pregnancy.

In the secretory phase there are significantly more lymphocytes to be found in the epithelium than during the proliferative phase.
