Abstract
2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), the most toxic congener of dioxins, has a proven reproductive toxicity. Due to the lack of evidence on the multigenerational female reproductive toxicity of TCDD through the maternal exposure, the current study aims to evaluate, on the one hand, the acute reproductive toxicity of TCDD on adult female pre-gestational exposed to a critical single dose of TCDD (25 μg/kg) for a week (group referred to as AFnG; adult female/non-gestation). On the other hand, the transcription, hormonal and histological effects of TCDD on the females of two generations F1 and F2, were also investigated after the exposure of pregnant females to TCDD on gestational day 13 (GD13) (group referred to as AFG; adult female/gestation). First, our data showed alternations in the ovarian expressional pattern of certain key genes involved in the detoxification of TCDD as well as in the biosynthesis of steroidal hormones. The expression of Cyp1a1 was highly induced in TCDD-AFnG group, but reduced in both F1 and F2. While the transcripts levels of Cyp11a1 and 3βhsd2 were decreased, Cyp19a1 transcripts were increased as a function of TCDD exposure. This was synchronized with a dramatic increase in the level of estradiol hormone in the females of both experimental groups. Beside a significant reduce in their size and weight, ovaries of TCDD-exposed females showed serious histological alterations marked by atrophy of the ovary, congestion in the blood vessels, necrosis in the layer of granular cells, dissolution of the oocyte and nucleus of ovarian follicles. Finally, the female fertility was dramatically affected across generations with a reduced male\female ratio. Our data indicate that the exposure of pregnant female to TCDD has serious negative effects in the female productive system across generations and suggest the use of hormonal alternation as biomarker to monitor and assess the indirect exposure of these generations to TCDD.

Kelulut Honey Improves Folliculogenesis, Steroidogenic, and Aromatase Enzyme Profiles and Ovarian Histomorphology in Letrozole-Induced Polycystic Ovary Syndrome Rats. Nutrients 2022; 14:4364. [PMID: 36297046 PMCID: PMC9612175 DOI: 10.3390/nu14204364] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Revised: 10/09/2022] [Accepted: 10/14/2022] [Indexed: 11/16/2022] Open
Abstract
Polycystic ovary syndrome (PCOS) has been linked to aberrant folliculogenesis and abnormalities in the aromatase enzyme (Cyp19a1) and the steroidogenic enzyme, 17-alpha-hydroxylase (Cyp17a1) expression. It has been demonstrated that Kelulut honey (KH) improves both female and male reproductive system anomalies in animal studies. Here, we examined the effects of isolated and combined KH, metformin, and clomiphene in improving folliculogenesis, aromatase, and steroidogenic enzyme profiles and ovarian histomorphology in letrozole-induced PCOS rats. Letrozole (1 mg/kg/day) was administered to female Sprague-Dawley (SD) rats for 21 days to induce PCOS. PCOS rats were subsequently divided into six experimental groups: untreated, treatment with metformin (500 mg/kg/day), clomiphene (2 mg/kg/day), KH (1 g/kg/day), combined KH (1 g/kg/day) and metformin (500 mg/kg/day), and combined KH (1 g/kg/day) and clomiphene (2 mg/kg/day). All treatments were given orally for 35 days. We found that KH was comparable with clomiphene and metformin in improving the expression of Cyp17a1 and Cyp19a1, apart from enhancing folliculogenesis both histologically and through the expression of folliculogenesis-related genes. Besides, the combination of KH with clomiphene was the most effective treatment in improving the ovarian histomorphology of PCOS rats. The effectiveness of KH in restoring altered folliculogenesis, steroidogenic, and aromatase enzyme profiles in PCOS warrants a future clinical trial to validate its therapeutic effect clinically.

Abstract
Background Polycystic ovary syndrome (PCOS) is a complex reproduction and endocrine disorder of women in the reproductive age. Spearmint (Mentha spicata L.) has anti-androgenic activity and flaxseed (Linum usitatissimum L.) contains phytoestrogen and was reported to improve PCOS conditions. This study aimed to evaluate PCOS conditions following administration of a mixture of these two plants. Methods Twenty-four rats with regular cycles were randomly divided into four groups as control (C) and treatment-control (TC) received a combination of spearmint extract (SE) + flaxseed extract (FE). PCOS was induced in PCOS and treatment (T) groups by a single intramuscular injection of estradiol valerate. The treatment group received a combination of SE and FE for 30 days, 7 weeks after injection of estradiol valerate. Estrous cycles were monitored for 10 days and in the last day animals were sacrificed, ovaries were collected for the histomorphometric study and the serum levels of progesterone, testosterone, estradiol, and dehydroepiandrosterone (DHEA) were measured. Result Significant rise in progesterone and a decrease in testosterone and estradiol with no significant change of DHEA in the T group, was observed in comparison with the PCOS group (P < 0.05). No significant difference noticed between T and control groups (C &CT) regarding evaluated hormones. A significant increase in primary, pre-antral and antral follicles noticed in the T group compared to the PCOS group. The number of cystic follicles decreased in the T group compared with the PCOS group. Granulosa layer thickness increased while the thickness of theca decreased significantly in the T group compared to the PCOS group (P < 0.05). No significant endocrine or histological differences noticed between C and TC groups. Conclusion A combination of flaxseed and spearmint extract improved the endocrine profile and the histomorphometric features of the ovary in the T group compared to the PCOS group.

Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS) is a serious endocrine disorder. In the present study, we investigated the therapeutic effects of erdosteine in letrozole-induced PCOS in rats. METHODS Thirty-two Wistar albino female rats were grouped as control group (C), PCOS group (PCOS), PCOS-metformin group (PCOS+MET), and PCOS-erdosteine group (PCOS+Erd). PCOS was induced by administering letrozole; such rats presented with sex hormone disorder, abnormal estrous cycles determined by daily vaginal smear, large cystic follicles, and increasing fasting insulin levels. After induction of PCOS, metformin (500 mg/kg/day) and erdosteine (100 mg/kg/day) were given orally to the treatment groups for 30 days. Serum concentrations of glucose, total cholesterol, low- and high-density lipoprotein, triglyceride, as well as the total oxidant and antioxidant status, oxidative stress index, circulating estrone (E1), estradiol (E2), testosterone, and androstenedione were evaluated. The ovaries were graded histologically. RESULTS Weights of ovarian tissues (p < 0.05) and the number of atretic follicles (p < 0.001) and cystic follicles (p < 0.01) decreased in the PCOS+Erd group; the corpus luteum number was significantly higher in the PCOS+Erd group (p < 0.01) as compared with the PCOS group. Lipid parameters (total-C, LDL-C, and TG), E1 (estrone), E1/E2 ratio, testosterone, and androstenedione significantly decreased, while HDL-C and E2 (estradiol) significantly increased in the PCOS+Erd group as compared with the PCOS group. Moreover glucose, insulin, and HOMA-IR were reduced with treatment of erdosteine (p > 0.05, p < 0.001, and p < 0.001, respectively). CONCLUSION It is suggested that erdosteine may be used in the treatment of PCOS as an alternative to metformin. It appears that our findings might be supported by clinical and molecular studies.

Abstract
The aim of this study was to determine the effect of ursodeoxycholic acid (UDCA) treatment on a polycystic ovary syndrome (PCOS) rat model. Thirty-two female Wistar-Albino rats were randomly divided into four groups as follows - group 1: sham group (n: 8), group 2: letrozole-induced PCOS group (n: 8), group 3: letrozole-induced PCOS plus metformin-treated (500 mg/kg) group (n: 8) and group 4: letrozole-induced PCOS plus UDCA (150 mg/kg)-treated group (n: 8). Histopathologic examination of the ovaries, circulating estrone (E1), estradiol (E2), testosterone, androstenedione, glucose, insulin and lipid profiles were evaluated. Histopathologic examination results revealed that groups 3 and 4 had significantly lower cystic and atretic follicles compared to group 2. Besides, group 4 had significantly higher antral follicles than group 2 (8.5 ± 2.9 versus 5.4 ± 1.1; p: 0.001). Furthermore, total testosterone (4.9 ± 2.8 versus 8.8 ± 2.9; p= 0.004) and insulin levels were significantly lower in group 4 compared to group 2 (1.7 ± 0.08 versus 2.1 ± 0.5; p = 0.02). However, lipid parameters, E1, E2, glucose and HOMA-IR were comparable between the groups. Our study results demonstrated that UDCA therapy improves ovarian morphology and decreases total testosterone and insulin levels.
