The significant improvement in ovarian PCOS syndrome using hydralazine and alendronate aromatase inhibitor FDA-approved drugs in Wistar rat models. Biomed Pharmacother 2024; 174:116504. [PMID: 38552442 DOI: 10.1016/j.biopha.2024.116504] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 03/22/2024] [Accepted: 03/27/2024] [Indexed: 05/01/2024] Open
Abstract
Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility. The aim of this study was to investigate the therapeutic potential of vitamin C, glutamine, mesalazine, hydralazine, and alendronate as new drug candidates for the treatment of letrozole-induced PCOS in female Wistar rats. PCOS was induced in rats by intramuscular injection of estradiol valerate (2 mg/kg body weight for 28 days). The rats then received normal saline (PCOS group), letrozole (0.5 mg/kg), vitamin C (100 mg/kg), glutamine (1000 mg/kg), mesalazine (200 mg/kg), hydralazine (30 mg/kg), and alendronate (17.5 mg/kg). Serum testosterone, LH, FSH, estradiol and progesterone levels were determined by ELISA method. H&E staining was used for histological analysis in the ovarian tissues. The groups treated with hydralazine and alendronate, show a significant decrease in testosterone, LH hormone, cystic and atretic follicles, and a significant increase in the number of single layer, multilayer, antral, graafian follicles and the volume of corpus luteum as compared to the PCOS group. Hydrolazine and alendronate appear to be effective in restoring folliculogenesis and increasing ovulation in PCOS rat. So that the natural process of ovulation and the improvement of the histology of polycystic ovaries and its shift towards healthy and active ovaries were observed. This finding supports the potential beneficial effect of hydrolazine and alendronate on improving PCOS complication.

Abstract
CONTEXT It has been suggested that thylakoid supplementation could be associated with favorable changes in appetite. However, the present trials are inconsistent. OBJECTIVE This systematic review and meta-analysis aimed to investigate whether thylakoid supplementation is effective in hunger/fullness changes. DATA SOURCES A comprehensive literature search was performed before conducting a systematic search in PubMed, Scopus, and ISI Web of Sciences databases up to May 2023. DATA EXTRACTION Of the 262 articles found, 5 articles that measured hunger fullness expressed as ratings on the visual analog scale (VAS) for appetite analyses were selected and thoroughly examined. Relevant information, such as the authors' names, year of publication, country of origin, study design, number and status of participants, intervention dosage and type, study duration, assay used, and key findings, was extracted from these articles. The Jadad scale was used to evaluate the quality of studies. DATA ANALYSIS The data were obtained using STATA version 13 (StataCorp). Effect sizes were reported as weighted mean differences (WMDs) and 95% confidence intervals (CIs). Subgroup analyses were performed to estimate whether the effects of thylakoid supplementation on hunger and fullness varied according to dose, intervention duration, baseline population age and body mass index, baseline hunger and fullness, total sample size, and study quality. Fractional polynomial modeling was carried out to estimate time- and dose-response meta-analysis of the association between thylakoid and satiety and fullness. The meta-analysis also suggests a significant association between the combination of thylakoids with meals and reduced hunger (WMD: -2.415 mm; 95% CI: -3.544, -1.287; P < 0.001) and increased fullness (WMD: +4.602 mm; 95% CI: 2.356, 6.848; P < 0.001). Further analysis showed that thylakoid supplementation with 2 doses of 5 g/day (P = 0.002) and 7.4 g/day (P = 0.021) is more effective in reducing the feeling of hunger during an intervention of less than 56 days (P < 0.001) and with a lower level of hunger (VAS <45 mm, P < 0.001). Furthermore, a significant increase in the perception of fullness was found at a duration of less than 84 days (P < 0.001) and baseline fullness of more than 45 mm (P < 0.001). CONCLUSIONS Supplementation with thylakoid shows favorable effects on reducing hunger and increasing fullness during a shorter intervention duration. Further trials are required to shed light on this relationship. SYSTEMATIC REVIEW REGISTRATION PROSPERO registration no. CRD42023432429.

[PMID: 38276279 PMCID: PMC10817691 DOI: 10.3390/life14010150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 07/15/2023] [Accepted: 07/17/2023] [Indexed: 01/27/2024] Open
Abstract
Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women that is characterized by fluid-filled sacs in the ovaries and various symptoms, including high androgen levels, endometrial irregularities, and cysts. Although the main cause of PCOS remains unknown, it has been linked to genetic, endocrine, and metabolic factors, and there are several treatment options, including lifestyle modifications, medications, and surgery. Natural products such as medicinal plants and fruits are being explored as potential treatments for PCOS because of their bioactive compounds with pharmacological effects related to antioxidant, antimicrobial, anticancer, and antidiabetic properties. Some of these compounds improve insulin sensitivity, reduce inflammation, and enhance glucose metabolism, thereby benefiting patients with PCOS. This mini-review examined the effects of natural products on PCOS, including their effects on ovarian histological changes, blood glucose, sex hormones, and lipid profiles, based on animal and human studies. This study suggests that the use of natural products as complementary medicines can be a promising resource for the development of effective therapeutics for PCOS; however, further research is needed to fully understand their benefits.

Abstract
OBJECTIVES The study aimed to explore the role and mechanism of WZBS recipe on PCOS. METHODS PCOS model was established. After modeling, PCOS rats were intragastrically administered with Diane-35 or WZBS recipe (6.93 g/kg/d). Then, the ovarian and uterine morphology were observed, the estrous cycle was assessed. HE and oil red O staining were conducted for ovarian morphological analysis and counting ovarian follicle and corpora lutea number. Furthermore, the serum content of testosterone (T) and sex-hormone-binding globulin (SHBG) were assessed by ELISA kits. The androgen receptor (AR), CX43 mRNA and protein expression were measured by q-PCR and Western blot. RESULTS WZBS recipe increased uterine implanted blastocysts, reduced cystic dilated follicles, and normalized estrous cycle in PCOS rats. Meanwhile, WZBS recipe alleviated ovarian injury, increased mature follicles and corpora lutea number in PCOS rats. Moreover, WZBS recipe decreased serum T content, AR expression and increased serum SHBG content, CX43 expression in PCOS rats. CONCLUSIONS This study reveals that WZBS recipe may attenuate PCOS by protecting follicular development via down-regulating AR.

J Ovarian Res 2023; 16:216. [PMID: 37968684 PMCID: PMC10652637 DOI: 10.1186/s13048-023-01288-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Accepted: 09/28/2023] [Indexed: 11/17/2023] Open
Abstract
BACKGROUND Women with polycystic ovary syndrome (PCOS) have higher intestinal mucosal permeability, leading to the lipopolysaccharide (LPS) leakage and endotoxemia. This, in turn, leads to oxidative stress (OS) and neuro-inflammation caused by the gut-brain axis, affecting the neurotrophic factors levels such as brain-derived neurotrophic factor (BDNF) and S100 calcium-binding protein B (S100 B) levels. In this study, it was hypothesized that the thylakoid membranes of spinach supplementation along with a hypocaloric diet may have improved the LPS levels, neurotrophic factors, and OS in PCOS patients. METHODS In this double-blind, randomized, placebo-controlled, and clinical trial, 48 women with obesity and diagnosed with PCOS based on Rotterdam criteria were randomly assigned to thylakoid (N = 21) and placebo groups (N = 23). A personalized hypocaloric diet with 500 calories less than the total energy expenditure was prescribed to all patients. The participants were daily supplemented with either a 5 g/day thylakoid-rich spinach extract or a placebo (5 g cornstarch) for 12 weeks along with a prescribed low-calorie diet. Anthropometric measurements and biochemical parameters were assessed at baseline and after the 12-week intervention. RESULTS A statistically significant decrease in the LPS levels (P < 0.001) and an increase in the BDNF levels (P < 0.001) were recorded for the participants receiving the oral thylakoid supplements and a low-calorie diet. Furthermore, significant decreases were observed in fasting blood glucose, insulin, homeostatic model of assessment for insulin resistance, free testosterone index, and follicle-stimulating hormone / luteinizing hormone ratio in both groups (P < 0.05). No significant differences were detected between the two groups regarding the changes in malondialdehyde, catalase, total antioxidant capacity, and S100B levels (P > 0.05). CONCLUSIONS In sum, the thylakoid membranes of spinach supplemented with a hypocaloric diet reduced the LPS levels, increased the BDNF levels, and improved the glycemic profile and sex-hormone levels; however, they had no effects on the OS markers levels after 12 weeks of intervention.

Abstract
Background Polycystic ovary syndrome (PCOS) is a heterogeneous medical condition with a cluster of metabolic and endocrine disorders including dyslipidemia, insulin resistance, and hyperandrogenism. Objective The present study aimed to determine the effects of single-dose and co-supplementation of vitamin D (vit D) and omega-3 (O3) on anthropometric and several biochemical factors in women with PCOS. Materials and Methods In this double-blind, randomized clinical trial, 80 PCOS women referred to Shahid Motahhari Clinic, Shiraz, Iran, from April to October 2017 were studied in 4 groups (n = 20/each) for 8 wk. The placebo group received the placebo capsule (paraffin oil); 1 weekly and 2/daily; the vit D group received vit D (50,000 IU/weekly) + 2 placebo capsules daily, O3 group, 2, O3 capsules daily + 1 placebo capsule weekly, and vit D + O3 (50000 IU/weekly vit D + 2, O3 capsules daily). Before and after 8 wk of intervention, height, weight, body mass index, waist circumference, triglycerides, total cholesterol (TC), high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, fasting blood sugar, homeostasis model of insulin resistance index, and sex hormone binding globulin were compared between groups. Results The significant reduction was detected in serum triglyceride (p = 0.002), TC (p = 0.04), fasting blood sugar (p = 0.02), insulin (p = 0.001), and homeostasis model of insulin resistance index (p = 0.001) concentrations in all vit D, O3, and vit D + O3 supplemented groups compared to the placebo group. Furthermore, in comparison with the placebo group, a significant increase was observed in serum sex hormone binding globulin levels after vit D, O3, and vit D + O3 treatments. Nevertheless, no significant changes were observed in serum high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and anthropometric indices in all treated participants. Conclusion The current study indicated that single dose and co-supplementation of vit D and O3 for 8 wk was associated with beneficial effects on serum triglyceride, TC, insulin, and sex hormone binding globulin concentrations among women suffering from PCOS.

Abstract
Introduction This study investigated the effects of 12 weeks of high-intensity functional training (HIFT) combined with spinach-derived thylakoid supplementation on some selected Adipokines and insulin resistance in males with obesity. Method Sixty-eight participants (mean age: 27.6 ± 8.4 yrs.; mean height: 168.4 ± 2.6 cm; mean weight: 95.7 ± 3.8 kg, mean BMI: 32.6 ± 2.6 kg/m2) were randomly divided into four groups of 17 per group: Control group (CG), Supplement group (SG), Training group (TG), and Training + supplement group (TSG). Following baseline measurements, the two training groups (TG and TSG) started the 12 weeks of exercise training program (3 sessions per week). A total of 36 sessions lasting up to 60 min were included in the HIFT program using the CrossFit program. The eligible participants received 5 g/day of thylakoid-rich spinach extract or matching placebo as 5 g/day of raw corn starch (one sachet, 30 min before lunch) for 12 weeks. Baseline assessments were obtained 48 hours before the start of the training protocols and 48 hours after the last training session in all groups. Results There were significant interactions (p<0.001 for all) between exercise and time for adiponectin (ES:0.48), leptin (ES:0.46), resistin (ES:0.3), omentin (ES:0.65), vaspin (ES:0.46), visfatin (ES:0.62), apelin (ES:0.42), RBP4 (ES:0.63), chemrin (0.36) and semaphorin3c (ES: 0.5). Plasma levels of semaphorin3c were significantly correlated (p<0.05) with body weight (r= 0.57), BMI (r= 0.43), FFM (r= -0.612), FAT (r= 0.768), VO2peak (r=-0.53), insulin (r= 0.756), glucose (r= 0.623), and HOMA-IR (r= 0.727). There were also significant group differences in insulin (ES: 0.77), glucose (ES: 0.21), and HOM-IR (ES: 0.44) (p<0.05). Discussion Our findings indicate that 12 weeks of HIFT supplemented with spinach-derived thylakoid reduced levels of leptin, resistin, vaspin, visfatin, apelin, RBP4, chemrin, semaphorin3c and insulin resistance while increasing adiponectin and omentin levels in men with obesity.

Abstract
AIM Polycystic Ovary Syndrome (PCOS) is a very common endocrine disorder in women. We investigate the effect of physical exercise on body composition, nutritional parameters, and oxidative stress in rats with PCOS. METHODS Female rats were into three groups: Control, PCOS, and PCOS + Exercise. PCOS was induced by letrozole (1 mg/kg via p.o.) for 21 days consecutively. Physical exercise was swimming, for 21 consecutive days, 1 h/day with 5 % load. In all groups, we assessed the nutritional and murinometric parameters, body composition, thermography, and oxidative stress in brown adipose tissue (BAT) and peri-ovarian adipose tissue (POAT). KEY FINDINGS In PCOS we observed an increase (P < 0.05) in body weight vs. the Control group. But, the PCOS + Exercise group prevent this weight gain (P < 0.05). The temperature in BAT, decrease (P < 0.05) in the PCOS group vs. Control group. PCOS + Exercise prevented this reduction (P < 0.05) in BAT temperature vs. PCOS groups. We observed decreases (P < 0.05) in Lee Index and BMI in POS + Exercise vs. PCOS group. In PCOS rats, we observed an increase (P < 0.05) in murinometric (SRWG, EI, and FE) and body composition parameters (TWB, ECF, ICF, and FFM) vs. the Control group. The PCOS + Exercise prevents (P < 0.05) these changes in all groups, compared with PCOS. Regarding the BAT, we observe an increase (P < 0.05) in MPO and MDA levels in the PCOS vs. Control group. PCOS + Exercise prevents (P < 0.05) these increases vs. the PCOS group. SIGNIFICANCE PCOS modifies body composition, and nutritional parameters, and induces changes in oxidative stress in BAT. Physical exercise prevented these alterations.

Abstract
BACKGROUND Nowadays, polycystic ovary syndrome (PCOS) is a prevalent cause of infertility affecting women of reproductive age around the world. Thymoquinone is a natural antioxidant, derived from Nigella sativa. OBJECTIVES The current study aimed to evaluate the protective effects of thymoquinone on the detrimental effects of PCOS rats induced with letrozole. METHODS Thirty-two female rats were randomly divided into four groups: (1) Control, (2) PCOS, (3) PCOS+5 mg/kg thymoquinone and (4) PCOS+10 mg/kg thymoquinone. Thymoquinone was administered every 3 days for 30 days. Ovaries were histopathologically and stereologically examined, and antioxidant and apoptotic enzymes gene expression in ovaries and sex hormones in serum were measured. RESULTS The number of unilaminar, multilaminar, antral, and graffian follicles, volume density of corpus luteum (p < 0.01), and GPx1 gene expression in ovaries and level of FSH in the blood increased in both thymoquinone groups when compared to untreated PCOS (p < 0.05). Ovaries in thymoquinone groups showed a significant reduction in the number of atretic follicles, ovary weight and volume, volume density of cortex and ovarian cysts, Bax gene expression (p < 0.01) and Bax/Bcl2 ratio as well as levels of luteinizing hormone (LH), LH/FSH ratio and testosterone (p < 0.05) in the blood of female rats when compared to PCOS group. Administration of thymoquinone restored the most detrimental effects of PCOS on ovaries (p < 0.01) and sexual hormones (p < 0.05) in rats. CONCLUSIONS These data suggest that thymoquinone has improved effects on ovarian function in the PCOS rat model. Therefore, thymoquinone might be useful as a protective agent and adjunct treatment in PCOS patients.

The effects of melatonin and metformin on histological characteristics of the ovary and uterus in letrozole-induced polycystic ovarian syndrome mice: A stereological study. Int J Reprod Biomed 2022; 20:973-988. [PMID: 36618831 PMCID: PMC9806248 DOI: 10.18502/ijrm.v20i11.12365] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2021] [Revised: 05/02/2022] [Accepted: 08/31/2022] [Indexed: 12/15/2022] Open
Abstract
Background Polycystic ovarian syndrome (PCOS) with anovulation, hyperandrogenism, ovarian and uterine histological changes, menstrual irregularities, etc. signs is an infertility type. It seems that melatonin and metformin can improve these abnormalities. Objective To evaluate the effects of melatonin and metformin on the ovary and uterus in PCOS-induced mice using stereological methods. Materials and Methods Seventy-two adult female BALB/c mice (8-wk-old, 20-30 gr) were randomly divided into control (distilled water, gavage), PCOS (90 µg/kg letrozole, gavage), PCOS+metformin (500 mg/kg, gavage), PCOS+melatonin (10 mg/kg, intraperitoneal injection), and PCOS+melatonin control (0.5% ethanol saline) groups (n = 12/each). Another PCOS group was kept for a month to ensure that PCOS features remained. Finally, a stereological evaluation of the uterus and ovary was carried out, and vaginal cytology and serum testosterone levels were assessed. Results PCOS mice treated with metformin and melatonin had lower testosterone levels, body weight, and more regular estrus cycles than the PCOS group (p ≤ 0.001). A significant decrease in conglomerate and daughter gland numbers, and primary, secondary, atretic, and cystic follicles numbers with a significant increase in primordial and Graafian follicles, and corpus luteum numbers (p ≤ 0.001) was seen in these treated mice. Also, endometrial vessels' volume and length significantly increased, but ovarian, endometrial, myometrial, stromal, and glands volume, and endometrial and myometrial thickness dramatically declined (p ≤ 0.001). Conclusion It appears that metformin and melatonin could restore the PCOS phenotype including estrus cycle irregularity, high testosterone level, and ovarian and uterine micromorphology to the control levels. However, the 2 treatments had similar effects on the examined parameters.

Abstract
OBJECTIVE To assess the protective effect of dark chocolate (DC) on the letrozole-induced rat model of polycystic ovary syndrome (PCOS). METHODS In this experimental study, 32 female Wistar rats, weighing (200 ± 20) g, were randomly categorized into 4 groups including control, letrozole (1 mg·kg·d), metformin (500 mg·kg·d) along with letrozole, and DC (500 mg·kg·d) along with letrozole for 28 d by oral gavage. Twenty-four hours after the last supplementation, direct blood sampling was taken from the heart to obtain blood serum for evaluation of sex hormones and gonadotropins, oxidative parameters, inflammatory cytokines, and ovarian tissue was examined for histology. RESULTS The DC treatment significantly improved PCOS signs, as demonstrated by the significant restoration of ovarian morphology and physiological functions as compared with the letrozole group. DC treatment also decreased ovarian interleukin-1β and tumor necrosis factor-α levels and improved total oxidative/antioxidative status as compared with the letrozole group. CONCLUSIONS Treating the animals with DC could alleviate the PCOS symptoms and reduced the toxic effects of letrozole in the ovary. This effect may mediate through antioxidant and antiinflammatory properties.

Abstract
Background Polycystic ovary syndrome (PCOS) is an endocrine disorder, affecting women of reproductive age. Ageratum conyzoïdes (AGC) is used traditionally in the treatment of fever, rheumatism, and ulcer. This study investigates the effects of AGC on ovarian-uterine in PCOS rats. Methods Female rats were randomized into four groups (n = 6). Group A control received 2 ml distilled water. Group B received a single dose of 4 mg/kg body weight (bwt) i.p estradiol valerate (EV). Group C received 500 mg/kg bwt AGC and group D received a single dose of 4 mg/kg bwt i.p EV followed by 500 mg/kg bwt AGC orally for 30 days. Parameters tested include follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), estradiol (E2), progesterone (P), C-reactive protein (CRP), interleukin (IL)-6, IL-18 and tumor necrosis factor (TNF)- α, malondialdehyde (MDA), superoxide dismutase (SOD), Catalase (CAT), total protein (TP), total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), and ovary and uterus histomorphometric. Results Ageratum conyzoides decrease insulin resistance, obesity indices, TC, TG, LDL, MDA, T, LH, FSH, CRP, IL-6, IL-18, and TNF- α in PCOS rats. And increase HDL, E2, P, TP, CAT, and SOD in PCOS rats. AGC improved ovary and uterus histo-architecture, tertiary, and Graafian follicles, corpus luteum and endometrial thickness increased,and cystic and atretic follicles decreased. Conclusion Ageratum conyzoides improved insulin sensitivity, antioxidant activities, hormonal imbalance, inflammatory makers, and histological changes in PCOS rats. Therefore AGC can be used as a potential adjuvant agent in the treatment of PCOS.

Ficus deltoidea ameliorates biochemical, hormonal, and histomorphometric changes in letrozole-induced polycystic ovarian syndrome rats. BMC Complement Med Ther 2021; 21:291. [PMID: 34844580 PMCID: PMC8628419 DOI: 10.1186/s12906-021-03452-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2021] [Accepted: 09/24/2021] [Indexed: 10/26/2022] Open
Abstract
BACKGROUND Insulin resistance and hormonal imbalances are key features in the pathophysiology of polycystic ovarian syndrome (PCOS). We have previously shown that Ficus deltoidea var. deltoidea Jack (Moraceae) can improve insulin sensitivity and hormonal profile in PCOS female rats. However, biological characteristics underpinning the therapeutic effects of F. deltoidea for treating PCOS remain to be clarified. This study aims to investigate the biochemical, hormonal, and histomorphometric changes in letrozole (LTZ)-induced PCOS female rats following treatment with F. deltoidea. METHODS PCOS was induced in rats except for normal control by administering LTZ at 1 mg/kg/day for 21 days. Methanolic extract of F. deltoidea leaf was then orally administered to the PCOS rats at the dose of 250, 500, or 1000 mg/kg/day, respectively for 15 consecutive days. Lipid profile was measured enzymatically in serum. The circulating concentrations of reproductive hormone and antioxidant enzymes were determined by ELISA assays. Ovarian and uterus histomorphometric changes were further observed by hematoxylin and eosin (H&E) staining. RESULTS The results showed that treatment with F. deltoidea at the dose of 500 and 1000 mg/kg/day reduced insulin resistance, obesity indices, total cholesterol, triglycerides, low-density lipoprotein cholesterol (LDL), malondialdehyde (MDA), testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) to near-normal levels in PCOS rats. The levels of high-density lipoprotein cholesterol (HDL), estrogen, and superoxide dismutase (SOD) are also similar to those observed in normal control rats. Histomorphometric measurements confirmed that F. deltoidea increased the corpus luteum number and the endometrial thickness. CONCLUSIONS F. deltoidea can reverse PCOS symptoms in female rats by improving insulin sensitivity, antioxidant activities, hormonal imbalance, and histological changes. These findings suggest the potential use of F. deltoidea as an adjuvant agent in the treatment program of PCOS.
