[PMID: 35357583 DOI: 10.1007/s00404-022-06538-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Accepted: 03/16/2022] [Indexed: 11/02/2022]
Abstract
PURPOSE This study was aimed to evaluate the protective effect of edaravone on cisplatin-induced ovarian injury. METHODS A total 40 female Wistar-Albino rats were utilized to form four groups: Group 1 (control group) (n = 10), no procedure was performed. Group 2 (cisplatin group) (n = 10), single-dose 7.5 mg/kg cisplatin was administered and no procedure was performed. Group 3 (edaravone group) (n = 10), single-dose 1 mg/kg edaravone was administered and no procedure was performed. Group 4 (cisplatin + edaravone group) (n = 10), single-dose 7.5 mg/kg cisplatin and 1 mg/kg edaravone were administered. Seventy-two hours later, ovaries were surgically extirpated in all groups. Malondialdehyde (MDA) levels and nitric oxide (NO) levels were studied in blood samples. In ovarian tissue samples, DNA damage and apoptosis were assessed using TUNEL method. Ovarian tissue damage was evaluated by immunohistochemical staining with caspase 3 and caspase 8. RESULTS According to the findings obtained from the study, edaravone showed protective properties on ovarian damage due to cisplatin. MDA and NO levels were significantly higher in cisplatin group than other groups. Histopathological ovarian tissue damage in the cisplatin group was significantly higher than other groups. Similarly, DNA damage and apoptosis were higher in cisplatin group and this difference was found to be statistically significant. The immunohistochemical staining which was done using caspase 3 and caspase 8 was revealed that immunoreactive cells were statistically higher in cisplatin group than cisplatin + edaravone group. CONCLUSION Edaravone seems to be effective in prevention of ovarian damage and short-term treatment.

Abstract
Objective(s): This study aimed to determine anti-inflammatory, antioxidant, and antiapoptotic properties of urapidil (Ura) against ovarian torsion detorsion (T/D) injury in rats. Materials and Methods: 40 female Wistar albino rats were grouped as sham, T/D, T/D+dimethyl sulfoxide (DMSO), T/D+Urapidil (Ura) 0.5 mg/kg (low dose), and T/D+Urapidil (Ura) 5 mg/kg (high dose) groups. In treatment groups, Ura was administered intraperitoneally just before detorsion. Biochemical parameters (TAS, TOS, MDA, MPO, and SOD) and immunohistochemical (IL-1β, TNF-α, NF-κB, LC3B, and Caspase-3) analyzes were performed. Results: In the T/D group, OSI and MPO levels were elevated significantly while TAS values decreased compared with the sham group. A significant difference occurred in the low dose treatment group in TAS and OSI levels compared with the T/D group. In the high dose treatment group, significant elevation in TAS but reduction in OSI and MDA levels were observed compared with the T/D group. Immunohistochemical staining resulted in IL-1β, TNF-α, NF-κB, LC3B, and caspase-3 immunopositivity in the T/D group, while Ura treatment decreased those parameters. Intensive congestion and hemorrhage were observed in the T/D group, but contrary to this, treatment groups had alleviated congestion and hemorrhage. Conclusion: These results suggest that Ura demonstrated protective effects against ovarian T/D injury via anti-oxidative, anti-inflammatory, and anti-apoptotic features.

The long-term protective effect of hypothermia and gradual detorsion on ovarian tissue in adnexal torsion/detorsion model in rats. J Pediatr Surg 2020; 55:1639-1644. [PMID: 31706613 DOI: 10.1016/j.jpedsurg.2019.10.022] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2019] [Revised: 10/03/2019] [Accepted: 10/10/2019] [Indexed: 11/21/2022]
Abstract
INTRODUCTION Ischemia in ovarian torsion and subsequent reperfusion has significant effects on fertility in the long term. The most important reason for these changes is thought to be a reperfusion injury rather than ischemia. We aimed to evaluate whether the reperfusion injury following ovarian detorsion could be reduced by hypothermia and intermittent reperfusion. MATERIALS AND METHODS Forty adult female rats were divided into five groups as follows: Sham (Sh) (n = 8), torsion detorsion (control TD) (n = 8), progressive reperfusion "gradual detorsion" (GD) (n = 8), hypothermia (H) (n = 8) and the progressive reperfusion + hypothermia (GD + H) (n = 8). In all rats, except for the Sh group, the left ovary was rotated counter clockwise 1080° and fixed to the abdominal wall by three 5-0 non-absorbable sutures followed by the closure of the laparotomy. After 30 h, reperfusion was achieved following the detorsion of the ovaries. In both the control TD and H groups, the torsed ovaries were detorsed. H group, however, was subjected to hypothermia with ice packs 30 min before and during the detorsion. Tissue temperature was kept constant at 4 °C, controlled by a digital thermometer. In the GD group, the torsed ovary and pedicle were detorsed by 360°, followed by a 5 min pause. This procedure was repeated twice until a complete detorsion was achieved. GD + H group underwent hypothermia with ice packs 30 min before the procedure and the torsed ovary and pedicle were detorsed by 360°. After a 5 min pause, we repeated this process twice to provide full detorsion. The tissue temperature was constantly held at 4 °C. In the hypothermia groups, we applied hypothermia for an additional 30 min after detorsion and then left the rats at normal body temperature during reperfusion. We followed the rats in all groups for 60 days. Then we excised the left ovaries of all rats through laparotomy and spared some of the ovaries for biochemical and pathological examination. Intracardiac blood was taken at the end of the procedure and it was sent to the biochemical laboratory to assess oxidative stress markers. Finally, all the animals were sacrificed with high-dose of anesthesia. RESULTS Evaluation of the results revealed that oxidative stress markers were significantly lower, and antioxidant parameters were higher in the experimental groups compared with the control TD group (p < 0.05). Histopathologically, we found that tissues were preserved in GD, H, GD + H groups (p < 0.05). When we compared the groups among each other, both biochemical and histopathological values in GD + H group showed that the tissue was preserved from oxidative damage, albeit the difference did not reach a level of significance. DISCUSSION Several studies have shown that both hypothermia and intermittent reperfusion protect tissue from IR damage in the early period. However, as far as we know there is no study on long-term outcomes of both practices. Our study showed that both hypothermia and intermittent reperfusion alone protect tissue from IR damage in the long term. However, it did not show the superiority of the combination of both methods compared to that of individual application. The advantages of these methods lie in their easy application and cost-effectiveness. We believe that our study will serve as a base for future studies on the subject.

Abstract
Quality of life improvement stands as one of the main goals of the medical sciences. Increasing cancer survival rates associated with better early detection and extended therapeutic options led to the specific modeling of patients’ choices, comprising aspects of reproductive life that correlated with the evolution of modern society, and requires better assessment. Of these, fertility preservation and ovarian function conservation for pre-menopause female oncologic patients pose a contemporary challenge due to procreation age advance in evolved societies and to the growing expectations regarding cancer treatment. Progress made in cell and tissue-freezing technologies brought hope and shed new light on the onco-fertility field. Additionally, crossing roads with general fertility and senescence studies proved highly beneficial due to the enlarged scope and better synergies and funding. We here strive to bring attention to this domain of care and to sensitize all medical specialties towards a more cohesive approach and to better communication among caregivers and patients.

Abstract
Background This study was conducted to explore whether the effect of edaravone (5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol3-one, EDR) can ameliorate renal warm ischemia-reperfusion injury (IRI) by modulating endoplasmic reticulum stress (ERS) and its downstream effector after cardiac arrest (CA) and cardiopulmonary resuscitation (CPR) in a rat model. Methods The rats (n=10) experienced anaesthesia and intubation followed by no CA inducement were defined as the Sham group. Transoesophageal alternating current stimulation was employed to establish 8 min of CA followed by conventional CPR for a resuscitation model. The rats with successful restoration of spontaneous circulation (ROSC) randomly received EDR (3 mg/kg, EDR group, n=10) or equal volume normal saline solution (the NS group, n=10). At 24 hr after ROSC, serum creatinine (SCR), blood urea nitrogen (BUN) levels, and cystatin-C (Cys-C) levels were determined and the protein level of glucose-regulated protein (GRP78), C/EBP homologous protein (CHOP), extracellular signal-regulated kinase (ERK), phosphorylated extracellular signal-regulated kinase 1/2 (p-ERK1/2), Bax/Bcl-2, and caspase-3 were detected by Western blot method. Results At 24 hrs after ROSC, SCR, BUN and Cys-C were obviously increased and the proteins expression, including GRP78, CHOP and p-ERK1/2, cleaved-caspase 3 Bax/Bcl-2 ratio, were significantly upregulated in the NS group compared with the Sham group (p<0.05). The remarkable improvement of these adverse outcomes was observed in the EDR group (p<0.05). Conclusion In conclusion, we found that EDR ameliorates renal warm IRI by downregulating ERS and its downstream effectors in a rat AKI model evoked by CA/CPR. These data may provide evidence for future therapeutic benefits of EDR against AKI induced by CA/CPR.

Abstract
AIMS Signal peptide-CUB-EGF (epidermal growth factor-like protein) domain-containing protein 1 (SCUBE1) is an experimental marker of ischemia that has been previously studied both in rat models and humans. In this study, we aim to investigate the importance of SCUBE1 levels in ovarian torsion using an ovarian torsion model in rats. METHODS A total of 18 Sprague-Dawley rats were equally divided into three groups. Group 1 (n = 6) was the Sham group and was only given a laparotomy procedure. Group 2 (n = 6) underwent bilateral ovarian torsion and ovarian ischemia lasting 8 h. Group 3 (n = 6) was subjected to bilateral ovarian torsion and ischemia lasting 24 h. Blood samples were collected from all three groups after the operations, and SCUBE1 levels were studied. Ovarian samples were collected, and microscopic evaluation was performed. The correlation of SCUBE1 levels and histopathological findings were investigated. RESULTS The mean SCUBE1 level of group 3 was statistically higher than other groups (P < 0.01). Follicular degeneration and infiltration of inflammatory cells were, respectively, statistically significant in groups 2 and 3 (P = 0.002 and P = 0.045, respectively). CONCLUSION SCUBE1 can be useful in diagnosing ovarian torsion during the first 24 h, but more randomized controlled studies are necessary in order to implement it in clinical settings.

Abstract
Background The aim of this study was to evaluate the effects of Nigella sativa (N. sativa) oil (NSO) on ovarian oxidative damage following ischemia-reperfusion injury, using a rat model of ovarian torsion. Material/Methods Forty-eight female albino Wistar rats were divided into six groups: (Group 1) laparotomy only; (Group 2) intraperitoneal NSO (2 ml/kg), 1 hour following laparotomy; (Group 3) 3 hours of ovarian ischemia; (Group 4) 3 hours of ovarian ischemia followed by 3 hours of reperfusion; (Group 5) 3 hours of ovarian ischemia and 2 ml/kg of NSO 1 hour before laparotomy; (Group 6) 3 hours of reperfusion after 3 hours of ovarian ischemia and 2 ml/mg of NSO 1 hour before laparotomy. Results The antioxidant status, ceruloplasmin level, native thiol, total thiol, and disulfide levels of the control group (Group 1) were significantly increased compared with the ovarian ischemia-reperfusion group treated with NSO (Group 6) (p=0.003, p=0.002, p=0.006, p=0.001 and p=0.003, respectively); these levels in the ovarian ischemia group (Group 3) and ischemia-reperfusion group (Group 4) were statistically similar to those of the ovarian ischemia + NSO group (Group 5) and ovarian ischemia-reperfusion + NSO group (Group 6). Conclusions In this preliminary rat study, administration of NSO shortly after the onset of ovarian ischemia-reperfusion injury, did not significantly reduce levels of markers of oxidative injury. Further studies are required to evaluate the ovarian changes at the tissue level, and to determine the optimum dose of NSO.

Abstract
This study evaluated the effects of N-acetylcysteine (NAC) and enoxaparin on ovarian tissue preservation, ovarian reserve and oxidative damage following ovarian torsion/detorsion injury. Rats were divided into four groups (n = 6/group): control; ischaemia/reperfusion (I/R); I/R + NAC; I/R + enoxaparin. Twenty-four hours after detorsion, ovarian tissues were collected for histopathological analysis and measurement of tissue 8-OHdG, GSH, MDA, MPO and SOD concentrations, as well as pre- and post-operative circulating AMH concentrations. Administration of NAC resulted in more pre-antral follicles compared with enoxaparin treatment and haemorrhage and follicle cell degeneration were more pronounced in I/R + enoxaparin group than I/R + NAC group. Both NAC and enoxaparin led to a significant reduction in ovarian tissue 8-OHdG (P = 0.004 and P = 0.01, respectively) and MPO (P = 0.013 and P = 0.023, respectively) concentrations compared with I/R group, indicating a protective effect against I/R oxidative damage. Only NAC-treated animals showed a significant increase in GSH and SOD concentrations and decrease in MDA concentrations compared with I/R group (P = 0.007, P = 0.024 and P = 0.026, respectively). These results indicate that NAC is more effective than enoxaparin in minimizing ovarian damage and preserving ovarian reserve following ovarian torsion.

Abstract
OBJECTIVES Ischemia modified albumin (IMA) levels significantly increased and may be used as a diagnostic marker in ovarian torsion. The aim of this study is to investigate whether there was any correlation between IMA levels and histopathologic changes in experimental ovarian torsion. MATERIAL AND METHODS Fourteen Sprague-Dawley rats, each weighing 220-250 g were divided randomly into 2 groups; in Group 1, the control group (n = 7), only laparotomy was performed and in Group 2, the experimental group (n = 7), ovarian torsion was performed. Ischemia was performed for 3 h; following the ischemia period, the torsion was relieved by detwisting the adnexa and then the ovarian I/R protocol was applied for 3 h. Blood samples were taken from all of the rats to measure the IMA levels and the ovaries were surgically removed for histologic examination. A blinded pathologist examined and scored the samples. RESULTS The median (minimum-maximum) IMA values were 921.00 (870.00-966.00) ABSUs in the ovarian torsion group and 853.00 (782.00-869.00) ABSUs in the control group. The difference was statistically significant. In the correlation analysis, a significant and strong correlation was found between IMA levels and histopathologic changes (Spearman's rho = +0.987, p < 0.001). CONCLUSION Positive correlation was found between the IMA levels and the histopathologic severity of the disease. This finding is important for both diagnosis of the disease and patient follow-up. As a new marker in ovarian torsion, IMA may also indicate the severity of the ovarian histopathology.

Abstract
AIM To evaluate the antioxidant effects of thymoquinone (TQ) and to investigate the biochemical, histopathological and immunohistochemical changes in experimental rat ovarian torsion. METHODS A total of 48 female adult rats were used in this study and randomly divided into 7 groups: (1) sham operation; (2) bilateral 3-hour ovarian ischemia; (3) 3-hour ischemia and 3-hour reperfusion; (4) and (5) rats were administered 20 and 40 mg/kg of TQ, respectively, before 0.5 h of ischemia, and then 3 h of ovarian ischemia was applied; (6) and (7) 3-hour ovarian ischemia was applied; 2.5 h after the induction of ischemia, rats were administered the same doses of TQ; at the end of 3 h of ischemia, a 3-hour reperfusion was applied. Histologic changes under light microscopy, immunoreactivity for anticaspase-3 and serum levels of malondialdehyde, interleukin-6, catalase and glutathione peroxidase were noted and compared between the 7 groups. RESULTS Ischemia and ischemia/reperfusion cause a deterioration of biochemical and histopathological parameters. Administration of TQ seems to reverse these alterations and alleviate the injury. Antioxidant defense mechanisms appear to be enhanced by the administration of TQ. CONCLUSION TQ at different doses attenuates ovarian ischemia and ischemia/reperfusion injury in rats.

[PMID: 25783397 DOI: 10.1016/j.jpedsurg.2015.01.011] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2014] [Revised: 01/05/2015] [Accepted: 01/13/2015] [Indexed: 10/24/2022]
Abstract
PURPOSE Much attention has been given to hypothermia as it is effective in inhibiting inflammatory responses and also ischemia/reperfusion injury. Therefore, the aim of this study was to evaluate the effect of hypothermia on torsion/detorsion injury in rats. METHODS Twenty-eight rats were randomly divided into four groups of sham-operated (SG), adnexal torsion/detorsion group (TG), adnexal torsion/detorsion+hypothermia group (THG) and hypothermia group (HG). In the SG group, right ovaries were excised after 3-h fixation to abdominal wall. In the TG, right adnexal underwent 720° torsion in a counterclockwise direction for 3h and then excised after 3-h detorsion period. In the THG, after 3-h torsion period, ovaries were immediately subjected to hypothermia (4°C) for 30-min and they were excised after 3-h detorsioned period. In the HG, the right ovaries were subjected to hypothermia for 30-min and excised after 3-h fixation period. One half of each ovary was immediately stored for antioxidant enzyme activity and tissue lipid peroxidation. The remainder was fixed for histopathological examination. RESULTS Adnexal torsion and detorsion significantly increased the tissue level of Malondialdehyde, Superoxide dismutase and Reduced glutathione. On the other hand, hypothermia significantly reduced these oxidative stress parameters. The histopathological changes were less in the THG group; these changes were not statistically different from the other groups. CONCLUSION The results of this study suggested that hypothermia inhibited the production of oxidative stress in the ovaries subjected to torsion/detorsion injury.

Abstract
PURPOSE The purpose of the study is to evaluate the effect of vardenafil on the histopathology and biochemical parameters in reducing damage in experimental ovarian ischemia and ischemia/reperfusion injury in a rat model and to compare the effect of two different doses of vardenafil. METHODS Forty-two rats with experimental ovarian torsion. Group-I: sham; Group-II: ovarian ischemia; Group-III: 2 hours of ischemia followed by a 2-hour reperfusion. Group-IV: two hours before the sham operation, rats received 1mg/kg vardenafil; Group V and VI: A 2-hour period of ovarian ischemia was applied, in which rats were treated with intraperitoneal vardenafil 1 and 2mg/kg dose, after 1.5 hours of ovarian ischemia. After 2 hours of reperfusion, the ovaries on the right side were removed for examination. The ovarian ischemia/reperfusion injury was evaluated by calculating total antioxidant status, total oxidant status and oxidative stress index; and histopathologic examination of all ovarian rat tissue. RESULTS The histologic findings in vardenafil treatment groups were statistically significant decreased edema and follicle degeneration, with vascular congestion, hemorrhage and follicle degeneration being dose-dependent. There were no statistically significant changes in the biochemical parameters. CONCLUSIONS According to histopathological examination, low and high dose vardenafil is effective in attenuating ischemia-reperfusion induced ovary injury.

A nitric oxide-donor furoxan moiety improves the efficacy of edaravone against early renal dysfunction and injury evoked by ischemia/reperfusion. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2015; 2015:804659. [PMID: 25834700 PMCID: PMC4365375 DOI: 10.1155/2015/804659] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/15/2014] [Accepted: 02/13/2015] [Indexed: 12/31/2022]
Abstract
Edaravone (5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one, EDV) is a free-radical scavenger reduces organ ischemic injury. Here we investigated whether the protective effects of EDV in renal ischemia/reperfusion (I/R) injury may be enhanced by an EDV derivative bearing a nitric oxide- (NO-) donor furoxan moiety (NO-EDV). Male Wistar rats were subjected to renal ischemia (45 minutes), followed by reperfusion (6 hours). Administration of either EDV (1.2–6–30 µmol/kg, i.v.) or NO-EDV (0.3–1.2–6 µmol/kg, i.v.) dose-dependently attenuated markers of renal dysfunction (serum urea and creatinine, creatinine clearance, urine flow, urinary N-acetyl-β-D-glucosaminidase, and neutrophil gelatinase-associated lipocalin/lipocalin-2). NO-EDV exerted protective effects in the dose-range 1.2–6 µmol/kg, while a higher dose (30 µmol/kg) was needed to obtain protection by EDV. Both EDV and NO-EDV modulated tissue markers of oxidative stress and lipid peroxidation. NO-EDV, but not EDV, activated endothelial NO synthase (NOS) and blunted I/R-induced upregulation of inducible NOS, secondary to modulation of Akt and NF-κB activation, respectively. Besides NO-EDV administration inhibited I/R-induced IL-1β, IL-18, IL-6, and TNF-α overproduction. Overall, these findings demonstrate that the NO-donor moiety contributes to the protection against early renal I/R injury and suggest that NO-donor EDV codrugs are worthy of additional study as innovative pharmacological tools.

Abstract
BACKGROUND Proanthocyanidin is a potent bioactive antioxidant naturally occurring in grape seed and acts as reactive oxygen species (ROS) scavenger. The aim of this study was to investigate the effects of proanthocyanidinin in experimental ovarian torsion injury. METHODS Twenty four rats were randomly divided into three groups (n=8). Group 1: the laparotomy group, group 2: ovarian torsion group, and group 3: intervention group administered proanthocyanidinin of 50 mg/kg before bilateral ovarian ischemia and reperfusion. Histologic examination and scoring was done at the end of the experiment. Statistical analyses were performed using the SPSS v. 19. RESULTS Ovarian histopathologic findings of all three groups were significantly different in terms of hemorrhage (p<0.001), edema (p=0.001) and vascular dilatation (p< 0.001). Pathologic changes induced by I/R were reduced in ovaries of rats administered proanthocyanidin, in particular, hemorrhage, edema and vascular dilatation. CONCLUSION Proanthocyanidin, known as free radical scavenger and antioxidant, is protective against tissue damage induced by ischemia and/or ischemia/reperfusion in rat ovaries.

Abstract
Ovarian tissue preservation and retransplantation is a promising strategy to restore fertility in cancer survivors. Ischaemia accompanying ovarian tissue grafting, however, can lead to significant follicle loss. Transplantation of the whole ovary by vascular anastomosis has been considered as an alternative to prevent widespread ischaemic damage. In this study, the feasibility and function of transplanting whole ovary with intact vasculature were evaluated, with the goal of developing a xenograft model for studies using donated human ovaries. Whole-swine ovaries with vascular pedicles were perfused and transplanted as intact ovaries by anastomosis into irradiated ovariectomized nude rats (n = 10). The observation period was between 1 and 4 weeks. Fresh swine ovaries served as controls (n = 10). Ovarian stroma and follicle populations were assessed through histological examination in both transplanted and control ovaries. Most of the transplanted whole ovaries (n = 6) maintained stromal quality and all preantral follicle classes were represented, although follicle numbers decreased compared with fresh control. Four transplanted ovaries were fibrotic after 1-4 weeks within the nude rat. Our results demonstrate transplantation of whole-pig ovary into nude rats is possible and support development of this xenograft model system for human studies.

Abstract
Cisplatin is one of the most effective chemotherapeutic agents but injury may occur at higher doses. The aim of this study was to investigate the effect of bilberry on cisplatin induced toxic effects in rat ovary. Twenty-one female Wistar-Albino rats were utilized to form three groups: In group 1 (control group), each rat received intraperitoneal injection of 1 mL of 0.9 % NaCl saline solution during 10-days. In group 2 (cisplatin group), a single dose of 7.5 mg/kg b.w. cisplatin was given. In group 3 (cisplatin + bilberry group), a single dose of 7.5 mg/kg cisplatin and bilberry at 200 mg/kg b.w. were given for 10 days. Ovaries were surgically removed in all groups and prepared for biochemical and light microscopic investigations at the examination times. Malondialdehyde (MDA) levels and activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione-S-transferase (GST) of tissue samples were measured. Histopathological damages in cisplatin administrated rats were seen such as severe edema, vascular congestion, hemorrhage and follicular degeneration in the ovary tissue. Moderate pathological alterations were observed in rats treated with bilberry plus cisplatin. Cisplatin administration significantly increased MDA production and decreased SOD, CAT, GPx and GST activities in the ovarian tissue when compared to the control group (p < 0.05). Cisplatin + bilberry administration increased antioxidant enzymes activities and reduced MDA levels. Bilberry administration seems to reduce the cisplatin induced ovarian toxicity thus it alleviates free radical damage. But it dose not protect completely rat ovary tissues.

Abstract
Environmental contamination of drinking water with chromium (Cr) has been increasing in more than 30 cities in the United States. Previous studies from our group have shown that Cr affects reproductive functions in female Sprague Dawley rats. Although it is impossible to completely remove Cr from the drinking water, it is imperative to develop effective intervention strategies to inhibit Cr-induced deleterious health effects. Edaravone (EDA), a potential inhibitor of free radicals, has been clinically used to treat cancer and cardiac ischemia. This study evaluated the efficacy of EDA against Cr-induced ovarian toxicity. Results showed that maternal exposure to CrVI in rats increased follicular atresia, decreased steroidogenesis, and delayed puberty in F1 offspring. CrVI increased oxidative stress and decreased antioxidant (AOX) enzyme levels in the ovary. CrVI increased follicle atresia by increased expression of cleaved caspase 3, and decreased expression of Bcl2 and Bcl2l1 in the ovary. EDA mitigated or inhibited the effects of CrVI on follicle atresia, pubertal onset, steroid hormone levels, and AOX enzyme activity, as well as the expression of Bcl2 and Bcl2l1 in the ovary. In a second study, CrVI treatment was withdrawn, and F1 rats were injected with estradiol (E₂) (10 μg in PBS/ethanol per 100 g body weight) for a period of 2 wk to evaluate whether E₂ treatment will restore Cr-induced depletion of AOX enzymes. E₂ restored CrVI-induced depletion of glutathione peroxidase 1, catalase, thioredoxin 2, and peroxiredoxin 3 in the ovary. This is the first study to demonstrate the protective effects of EDA against any toxicant in the ovary.

Abstract
The aim of this study was to evaluate the role of vitamin E in follicular degeneration and to assess histopathological and biochemical changes following ischemia-reperfusion (IR) injury in rat ovaries. Twenty-eight Wistar albino rats were randomly divided into four groups: sham, 4h torsion, 24h detorsion, and a vitamin E group. Thirty minutes before detorsion, a single dose of 200mg/kg vitamin E was administered intraperitoneally. The ovarian histology score was determined, serum levels of malondialdehyde (MDA) and myeloperoxidase (MPO) were measured. The apoptosis of granulosa cells and the phospho-c-jun N-terminal kinase (p-JNK) and phospho-p38 (p-p38) immunoreactivities of these cells were determined. MDA and MPO levels were significantly increased in the torsion and detorsion groups. Hemorrhage, edema, and congestion were also apparent in these groups. In addition, the apoptotic index and the immunoreactivity of p-JNK were highest in the detorsion group, which also showed marked follicular degeneration. However, p-p38 activity was not affected by torsion-detorsion (TD) induction. Vitamin E ameliorated TD-induced histological alterations. It also decreased serum levels of MDA and MPO, reduced the activity of p-JNK in the ovaries, and reduced numbers of apoptotic follicular cells. In conclusion, these data indicate that vitamin E attenuated ovarian follicular degeneration by inhibiting the immunoreactivity of p-JNK and reducing the apoptosis of granulosa cells.
