Bisphenol A (BPA) is one of the synthetic monomer which can be found in the environment. Limited animal and human studies have demonstrated that BPA alters endocrine and or metabolic functions. The aims of the present study were to evaluate serum BPA level in marketing seller women with polycystic ovary syndrome (PCOS) and hormonal and metabolic effects of this exposure compared to a control paired group. In a case-control study, 62 PCOS women who work as marketing sellers and 62 healthy women with similar jobs were included. The two groups were body mass index (BMI)- and age-matched. Serum samples were analyzed for BPA content, fasting blood sugar (FBS), triglyceride, cholesterol, HDL and LDL levels, thyroid stimulating hormone (TSH) concentration, and LH:FSH ratio. Significant higher serum BPA content (0.48 ± 0.08 vs. 0.16 ± 0.04 ng/ml), triglyceride (103.05 ± 13.10 vs. 91.65 ± 12.52 mg/dl), cholesterol (165.05 ± 10.79 vs. 161.21 ± 10.31 mg/dl) levels and LH:FSH ratio (3.64 ± 0.86 vs. 0.62 ± 0.14) and significant lower TSH concentration (1.56 ± 0.68 vs. 2.15 ± 1.09 IU/ml) were detected in case against control group, respectively (P < 0.05). No significant differences were detected in FBS, LDL, and HDL levels between the two groups. Also, there were no significant associations between serum TSH concentration and BPA level neither in case (P = 0.269) nor in control (P = 0.532) groups. In BPA-exposed PCOS women, BPA level was higher than healthy women and this difference maybe the cause of significant differences in levels of triglyceride, cholesterol, TSH, and LH:FSH ratio. These observations confirm the potential role of BPA in PCOS pathophysiology.
Oral mucositis (OM) is one of the cancer chemotherapy-related side effects which can affect the quality of life of affected patients. This study was designed to investigate the healing effect of Elaeagnus angustifolia in 5-flurouracil (5-FU)-induced OM in golden hamster. Fifty-six adult male golden hamsters received three intraperitoneal injections of 5-FU at a dose of 60 mg/kg on days 0, 5, and 10. The cheek pouch mucosa was scratched superficially under local anesthesia. Then, two horizontal scratches were made across the everted cheek pouch on days 3 and 4. All treatments were started on day 12 for equal number of animals in control group with no treatments, gel base group that was treated with carboxy methyl cellulose as gel base which used in preparation of the topical gel, topical gel group that used gel containing 10% hydroalcoholic extract of E. angustifolia (HEEA) topically, and dietary group which was treated with 300 mg/kg HEEA. At 2 and 5 days after treatment, blood and pouch tissue sampling were done and analyzed for blood composition, tissue malondialdehyde (MDA) level, and myeloperoxidase (MPO) and superoxide dismutase (SOD) activities plus histopathological evaluations. Both topically and orally HEEA-treated groups showed a significant relief in OM compared to the control and base gel groups. However, the systemic form had higher efficiency in some parts especially decreasing the MPO (0.27 ± 0.17 vs. 0.56 ± 0.17 IU/L) and increasing SOD (6.46 ± 0.15 vs. 5.36 ± 0.18 IU/L) activities in pouch tissue in comparison to topical form mostly at 5 days after treatment. It seems that hydroalcoholic extract of E. angustifolia can be used as an appropriate drug choice for the treatment of oral mucositis based on its healing stimulatory and anti-inflammatory properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
