RESUMO

PURPOSE: To evaluate the impact of systemic cyclophosphamide treatment on the rat uterus and investigate the potential therapeutic effects of natural antioxidant preparations curcumin and capsaicin against cyclophosphamide side effects. METHODS: A 40 healthy adult female Wistar albino rats were used in this study. Rats were randomly divided into four groups to determine the effects of curcumin and capsaicin against Cyclophosphamide side effects on the uterus (n=10 in each group); Group 1 was the control group (sham-operated), Group 2 was the cyclophosphamide group, Group 3 was the cyclophosphamide + curcumin (100mg/kg) group, and Group 4 was the cyclophosphamide + capsaicin (0.5 mg/kg) group. RESULTS: Increased tissue oxidative stress and histological damage in the rat uterus were demonstrated due to the treatment of systemic cyclophosphamide chemotherapy alone. The level of tissue oxidant and antioxidant markers and histopathological changes were improved by the treatment of curcumin and capsaicin. CONCLUSION: Cytotoxic effects of natural alkylating chemotherapeutic agents like cyclophosphamide on the uterus can be prevented by curcumin and capsaicin.

RESUMO

OBJECTIVE: To evaluate the protective effects of glycyrrhetinic acid (GA) and chrysin (CH) on experimental ischemia-reperfusion (I/R) injury in rat ovaries using tissue oxidative stress marker levels, hormone levels, and histopathological scores. METHODS: Sixty healthy rats were randomly divided into six equal groups: control, I/R, I/R + CH (50 mg/kg/day), I/R + GA (100 mg/kg/day), CH (50 mg/kg/day), and GA (100 mg/kg/day). Biochemical, hormonal, and histopathological evaluations were performed on blood and tissue samples 14 days after CH and GA treatment. RESULTS: The antioxidant defense system parameters were significantly higher in the ovarian tissues of the I/R + CH and I/R + GA groups than in those of the I/R group. Serum follicle-stimulating hormone levels were significantly reduced, and serum anti-Müllerian hormone levels were significantly increased in rats treated with CH and GA compared with those in the I/R group. Additionally, the histopathological scores of the I/R + CH and I/R + GA groups were significantly improved compared with those of the I/R group. CONCLUSIONS: The significant improvements in tissue oxidative stress parameters, serum hormone levels, and histological scores observed in this study indicate that treatment with CH or GA may be a conservative approach to prevent I/R injury in adnexal torsion cases after the ovarian detorsion procedure.

RESUMO

The objective of this article is to analyze the effects of nerolidol and hesperidin treatment on surgically induced endometriosis in a rat model. Endometriosis was induced in 24 healthy adult female Wistar albino rats via homologous uterine horn transplantation. Three operations were performed on each rat. After the second operation, the rats were randomized into control, nerolidol, and hesperidin treatment groups, and medications were administered for 2 weeks. The effects of the drugs on the endometriotic foci were evaluated after the third operation. Compared with the endometriosis control group, the average volume of the lesions was significantly lower in rats treated with hesperidin and nerolidol. Malondialdehyde levels were significantly reduced in the nerolidol-treated group, and glutathione levels and superoxide dismutase activity were significantly elevated in the endometriotic foci of both the hesperidin- and nerolidol-treated groups compared with the endometriosis group. Hesperidin and nerolidol treatment also improved histological parameters, such as hemorrhage, vascular congestion, necrosis, and inflammatory cell infiltration in the endometriotic foci. The results of this study demonstrated that treatment with the potent antioxidants nerolidol and hesperidin caused a significant regression of surgically induced endometriotic foci in rats.

RESUMO

BACKGROUND: In recent years, cancer rates have been rising among reproductive-age women. Thus, chemotherapy exposure has become an important cause of premature ovarian failure (POF). There has been growing interest regarding the preservation and restoration of ovarian function before and after oncological treatment because of the reproductive risk of chemotherapeutics and improved long-term survival of cancer patients. In this study, we sought to analyze the effects of curcumin (CRC) and capsaicin (CPS) on cyclophosphamide-induced POF in a rat model. METHODS: POF in rats was induced by intraperitoneal injection of 200 mg/kg cyclophosphamide on day 1 and then 8 mg/kg/day for the following 14 days. After 14 days of cyclophosphamide administration, rats were randomly divided into three groups as follows (n = 10/group): POF, POF + CRC (100 mg/kg/day), and POF + CPS (0.5 mg/kg/day) to determine the effects of CRC and CPS on the cyclophosphamide-induced POF rat model. Biochemical, hormonal, and histopathological evaluations were performed on blood and tissue samples 14 days after the CRC and CPS treatments. RESULTS: Malonaldehyde levels were significantly reduced, and glutathione levels and superoxide dismutase activity were significantly increased, in ovarian tissues in the POF + CRC and POF + CPS groups compared with the POF group. In the POF group, we observed hemorrhage and prominent mononuclear cell infiltration beneath the germinative epithelium, vascular congestion in ovarian stroma, hemorrhage around the corpus luteum, and atresia in ovarian follicles. This histopathological damage was significantly improved by treatment with CRC and CPS. There was a significant reduction in serum follicle-stimulating hormone and luteinizing hormone levels in rats treated with CRC and CPS compared with the POF group. Moreover, the levels of estradiol and anti-mullerian hormone in rats treated with CRC and CPS were significantly increased compared with the control group. CONCLUSIONS: In conclusion, CRC and CPS treatment of rats with cyclophosphamide-induced POF had a beneficial effect on reducing ovarian damage by improving tissue oxidative stress marker levels, ovarian reserve marker levels, and histopathological parameters. The significant improvements in ovarian tissue histopathological damage and hormonal levels detected in this study indicate that treatment with CRC or CPS might be a conservative treatment approach for cyclophosphamide-induced POF.

RESUMO

AIM: The aim of this study was to determine the effects of obesity on amniotic fluid (AF) inflammatory markers in second-trimester AF, testing the hypothesis that there is a relationship between maternal body mass index (BMI) and fetal inflammatory exposure. METHODS: AF was obtained from 84 singleton pregnant women undergoing elective amniocentesis for karyotype analysis at 16-24 weeks of gestation between April 2014 and May 2016. The cell-free AF was used to analyze interleukin (IL)-1ß and IL-6, and matrix metalloproteinase (MMP)-1, MMP-6, and MMP-13. RESULTS: IL-1ß levels were significantly higher in class II-III obese patients than in class I obese, overweight, and normal weight patients (14.68 ± 1.37 vs. 13.34 ± 1.86 vs. 13.00 ± 2.22 vs. 10.78 ± 1.92, respectively; p < 0.05). IL-6 levels were lowest in the normal weight group and highest in class II-III obese patients. MMP-1, MMP-6, and MMP-13 levels were also significantly higher in class II-III obese patients than in the other groups. CONCLUSION: This study demonstrated that the fetuses of class II-III obese women are exposed in utero to higher cytokine and MMP levels than fetuses of lean women. Modification of current cutoff levels of intra-amniotic cytokines and MMPs according to the BMI could improve the accuracy of the prenatal diagnosis of intra-amniotic infection and inflammation.

RESUMO

Achondroplasia is the most prevalent form of dwarfism, and there is little evidence about the optimal management of pregnant women with achondroplasia. We presented a 25-year-old primigravid woman with achondroplasia who was followed up during the pregnancy period and performed elective caesarean section with combined spinal-epidural anaesthesia at the 38th week of gestation. Frequent obstetric follow-up visits and invasive prenatal diagnostic tests should be offered during the antenatal period due to the increased risk for obstetric complications, such as premature delivery and fetal anomalies. Prenatal detailed counselling, comprehensive evaluation of the potential risks, obstetric and perioperative management should be performed by a multidisciplinary care team, including an obstetrician, anaesthesiologist, pulmonologist, cardiologist and neonatologist.

RESUMO

Objectives. In this study, we aimed to demonstrate the perinatal and neonatal outcomes of patients who were diagnosed with neural tube defect (NTD) in the midtrimester fetal ultrasound scan and refused the request for termination of pregnancy. Material and Methods. The records of 69 patients, for whom NTD was detected in the midtrimester fetal ultrasound scan and who preferred the continuation of the pregnancy after comprehensive counselling about the possible prognosis and treatment options during the period between January 2011 and February 2016, were reviewed retrospectively. Results. Of these patients, 66.7% were 25-35 years old; 95.7% were multiparous; and 1.4% had a history of a fetus having NTD in previous pregnancies. There were 7 (10.1%) neonatal deaths in these patients. Meningomyelocele closure procedure was the most performed surgery in the postnatal period (92%). Of these patients, 30.7% had paraplegia; 51.6% had neurogenic bladder; and 6.4% had infections due to surgery. Conclusion. The results of this study demonstrated perinatal and neonatal outcomes of fetuses with NTD who were not terminated by the preference of the family in midtrimester. The experience of our centre would be beneficial as a tool for nondirective counselling of these patients when considering the antenatal/postnatal care options and postnatal prognosis.

RESUMO

OBJECTIVE: To compare the prevalence of various metabolic and cardiovascular risk factors and insulin resistance between polycystic ovary syndrome (PCOS) patients with or without hyperandrogenism. MATERIAL AND METHODS: This is a retrospective cross-sectional study involving women with PCOS as diagnosed according to the Androgen Excess (AE) Society definition (n=504) and women with normoandrogenemic PCOS (n=183). Anthropometrics, lipid profile, glucose, insulin, oral glucose tolerance test (OGTT), and reproductive hormone levels were evaluated. RESULTS: Women with PCOS diagnosed according to the AE Society had a significantly higher prevalence of metabolic syndrome compared with the normoandrogenemic PCOS phenotype: odds ratio (OR) 2.95 [95% confidence interval (CI) 1.21-7.21]. There was no significant difference in the prevalence glucose intolerance test between the groups [OR: 2.15, 95% CI 0.71-6.56]. The prevalence of low high density lipoprotein (HDL)-cholesterol in the group under the AE-PCOS Society criteria was higher than that of the normoandrogenemic PCOS group [OR: 2.82, 95%CI 1.29-3.36]. CONCLUSION: The risks of metabolic syndrome and cardiovascular disease may vary among the phenotypes of PCOS based on the Rotterdam criteria. This new data may be of reference in informing women with PCOS, although further prospective studies are needed to validate this proposition.

RESUMO

OBJECTIVE: To evaluate percentage changes in serum beta-human chorionic gonadotropin (ß-hCG) values between days 0-1, 0-4 and 0-7 as an indicator of methotrexate therapy success in extra-uterine pregnancies. MATERIAL AND METHODS: Women with ectopic pregnancy treated with single-dose methotrexate therapy between January 2011 and August 2012 were assessed. Recorded data were reviewed electronically from patient files. All women (n=93) with an ectopic pregnancy treated medically with intramuscular methotrexate (50 mg/m(2)) were included. The percentage changes in serum ß-hCG levels from day 0 to 1, day 0 to 4 and day 0 to 7 were calculated for each case. RESULTS: The median ß-hCG values decreased between days 0 and 4 by 55.8%, and 89.6% of these cases were treatment successes. The median initial serum ß-hCG values were lower in women with successful treatment, but this was not statistically significant (p=0.11). CONCLUSION: A decline in serum ß-hCG values between days 0 and 4 appears to be the best predictor. It would be beneficial to determine whether a woman with an ectopic pregnancy treated with single-dose methotrexate administration will be treated successfully.
