摘要
Melanosis is a rare benign entity defined by the deposition of brownish-black pigment in a wide variety of organs especially the gastrointestinal tract, peritoneum, fallopian tubes and ovaries. Melanosis of the fallopian tube is widely known as pigmentosis tubae. Literature has mentioned ovarian teratomas and serous cystadenomas to be associated with the ovarian and peritoneal melanosis. We report five such cases of tubo-ovarian melanosis. The cases include mature teratoma and serous cystadenoma as well as melanosis of the fallopian tubes with otherwise normal ovarian histology. The importance of recognising this entity lies in its differential diagnosis.
摘要
To assess the oxidative stress across the cell membrane in patients suffering from pregnancy induced hypertension, erythrocyte malonyldialdehyde, vitamin E, reduced glutathione, glucose-6-phosphate dehydrogenase activity and plasma urate levels were estimated in 25 non pregnant women, 40 normotensive pregnant women and 40 women with pregnancy induced hypertension (PIH). As compared to non pregnant women, there was a significant increase in the levels of erythrocyte malonyldialdehyde and plasma urate in normotensive pregnant women, which were further increased in women with PIH. Erythrocyte glutathione levels were raised in normotensive pregnant women as compared to non pregnant women. Its levels were decreased in patients of PIH as compared to normotensive pregnant women. Cellular bio-availability of vitamin E was depressed in both normotensive pregnancy as well as patients with pregnancy induced hypertension as compared to non pregnant women.
