Endometrial polyps: Is the prediction of spontaneous regression possible?

Objective@#Endometrial polyps have been considered as a hyperplastic growth of endometrial stromal and glandular tissues. Even asymptomatic polyps in premenopausal women are usually removed as soon as they are diagnosed, although it is still unknown how often endometrial polyps disappear spontaneously. The aim of this study was to investigate the regression rate of endometrial polyps and the possible factors related to their spontaneous regression. @*Methods@#A total of 197 women with endometrial polyps were treated with operative hysteroscopy between January 2017 and April 2019 at our tertiary center. Of these, 123 patients who preferred conservative follow-up were enrolled in the study. Clinical and pathological data were obtained from electronic medical records. @*Results@#Patients with endometrial polyps were followed up for a median period of 62 days (range 30–360 days). Most women with endometrial polyps (84%) were reported to have gynecologic symptoms. Spontaneous polyp regression was observed in 28 (23%) patients who underwent surgery reevaluation. Patient age (<45 years), premenopausal period, and polyp size (<2 cm) were found to be associated with spontaneous endometrial polyp regression (P<0.05). We also observed more polyp regression in women with abnormal uterine bleeding (P=0.05). Second-look hysteroscopy showed that all postmenopausal women had persistent endometrial polyps. @*Conclusion@#Patient age (<45 years), premenopausal period, polyp size (<2 cm), and abnormal uterine bleeding may be associated with spontaneous endometrial polyp regression.

Biological and histopathological investigations of moclobemide on injured ovarian tissue following induction of ischemia-reperfusion in rats

The effects of moclobemide on damaged ovarian tissue induced by is-chemia-reperfusion and damaged contralateral ovarian tissue were investigated in rats, biochemically and histologically. In this experimental study, 40 rats were equally divided into four groups: 10 mg/kg moclobemide, 20 mg/kg moclobemide, ischemia/reperfusion control, and intact control groups. A 2-2.5-cm-long vertical incision was made in the lower abdomen of each rat in order to reach the ovaries, after which a vascular clip was placed on the lower side of the right ovary of each animal in the two treatment groups and the ischemia-reperfusion control group, but not in the healthy [intact control] animal group. The purpose of this procedure was to create ischemia over the course of three hours, then the clips were unclamped to provide reperfusion for the next two hours. At the end of the two hours of reperfusion, all the animals were killed by high-dose anaesthesia and their ovaries were taken and subjected to histological and biochemical [malondialdehyde, nitric oxide, glutathione] studies. The obtained results showed that moclobemide suppressed nitric oxide and malondialdehyde production in the ischemia - reperfusion damage area, and prevented the decrease in endogenous antioxidant levels [glutathione] in the rat ovarian tissue. Moclobemide also prevented infiltration of leukocytes to the ovarian tissue. These results showed that moclobemide protected ovarian tissue against ischemia-reperfusion injury. This study shows that moclobemide represses malondialdehyde and nitric oxide production in the rat ovarian tissue subjected to ischemia-reperfusion injury and keeps the endogenous antioxidant glutathione level from decreasing. Moclobemide also inhibits leukocytic migration into ovarian tissue following ischemia-reperfusion injury. From these results, it is suggested that moclobemide can be used in the treatment of ovarian ischemia-reperfusion injury

effect of metyrosine/prednisolone combination to oophorectomy-induced osteoporosis

Osteoporosis is a chronic disease characterized by a decrease in bone mineral density [BMD] and corruption of the microarchitectural structure of bone tissue. It was investigated whether methylprednisolone had a favorable effect on osteoporotic bone tissue in Oophorectomy induced osteoporotic rats whose endogenous adrenaline levels are suppressed with metyrosine. Bone Mineral Density, number of osteoblast-osteoclast, bone osteocalcin levels and alkaline phosphatase [ALP] measurements were performed. Obtained results were compared with that of alendronate. Oophorectomy induced osteoporosis was exacerbated by methylprednisolone. Alentronate prevented ovariectomised induced osteoporosis, but it couldn't prevent methylprednisolone +ovariectomised induced osteoporosis in rats. Combined treatment with methylprednisolon and metyrosine was the best treatment for preventing osteoporosis but metyrosine alone couldn't prevent osteoporosis in ovariectomised rats

Investigation of the relationship of some antihypertensive drugs with oxidant/antioxidant parameters and dna damage on rat uterus tissue

In this study, we investigated the effects of treatment with chronic antihypertensive drugs [clonidine, methyldopa, amlodipine, ramipril and rilmenidine] on oxidant-antioxidant parameters and toxic effects on DNA in rat uterus tissue. In addition, uterus tissues were examined histopathologically. A total of 36 albino Wistar rats were divided into the following six groups: 0.075 mg/kg clonidine group; 100 mg/kg methyldopa group; 2 mg/kg amlodipine group; 2.5 mg/kg ramipril group; 0.5 mg/kg rilmenidine group; and the healthy group. Rats underwent chronic drug administration for 30 days and at the end, biochemical and histopathological examinations were performed. All data were subjected to one-way ANOVA test. We divided these drugs into the following three groups according to their effects on rat uteri: [I] mild negative effects [clonidine], [II] moderate negative effects [rilmenidine, methyldopa] and [III] drugs which had severe negative effects [amlodipine, ramipril]. These data may help with selection of antihypertensive drugs, in order to determine which drugs have the lowest toxicity in pregnant and non-pregnant [pre-pregnancy] women
