Salpingitis associated with the presence of nonmedicated IUDs.

Fallopian tube tissue obtained at Pomeroy sterilization of 75 normally cycling women, 75 women 2 to 3 days postpartum, and 75 asymptomatic women who had used a nonmedicated IUD for at least a year was examined histologically. There was an increased frequency of tissue edema and congestion in the postpartum group only. The frequency and extent of acute inflammatory changes in the three groups was not significantly different.

Absence of capillary microangiopathy in oral contraceptive users with glucose intolerance.

The possible vascular hazard associated with carbohydrate intolerance produced by long-term use of oral contraceptives was investigated by examining the capillary basement membrane thickness in quadriceps muscle biopsies, a highly sensitive and reliable indicator of diabetic microangiopathy. The average basement thickness of 18 long-term (4-9 years) contraceptive users with diminished carbohydrate tolerance was 1644 A, compared to normal pregnant women (1711 A) prediabetic pregnant women (1854 A), and overt diabetic women (2593 A). Contraceptive steroid-induced carbohydrate intolerance appears to carry little, if any, increased risk for the development of diabetic vascular disease, even as assessed by the sensitive electron microscopic technique.

Histology of the baboon endometrium during the menstrual cycle and pregnancy.

The histologic characteristics of baboon endometrium during the menstrual cycle and pregnancy were studied and compared with those of human endometrium. Eight phases of endometrial change during the menstrual cycle are described. The samples were dated on the basis of sex skin changes.
