RESUMO
Effects of Ovulen-21, Demulen, Enovid-E and Ovral on zinc and copper levels in human plasma and endometrium during the menstrual cycle have been studied. Both plasma and endometrium copper levels were significantly elevated above the control values (P less than 0.001) in women taking oral contraceptives while the zinc levels remained reasonable constant.

Hydrocarbons of the human ovary and Fallopian tube have been studied by temperature-programmed gas chromatography. The major compounds present are a series of n-alkanes (C16 to C40), with the addition of iso and anteiso hydrocarbons. The human ovary and Fallopian tube hydrocarbons did not show significant changes during the menstrual cycle.

PIP: Vaginal smears were taken daily from 27 rats 4-6 months of age to determine the stages of the estrous cycle. The ovaries were removed surgically, and 1 ovary was used for electron microscopy and the other for histochemical studies. The perifollicular region was defined as that space between the granulosa cells and the theca interna and was characterized by a basement membrane, reticular fibers, amorphous material, and fibroblasts. Variations were noted in this region during the estrous cycle. In early estrus, fibers and amorphous material were present, but at the time of ovulation fibroblasts replaced these fibers. These changes in the structure of the perifollicular region during the estrous cycle probably give mechanical support to the follicle during its development. It was suggested that their structure is hormone sensitive.^ieng
