Abstract
BACKGROUND One of the most dangerous gynecological emergencies is ovarian ischemia that commonly occurs during surgical manipulation or presence of ovarian masses. OBJECTIVES finding new therapies to prevent the associated harmful effects of ischemia/reperfusion-induced damage is still a critical need. For the first time, we aimed to evaluate the possible role of phosphodiesterase (PDE) 3 A inhibitor (PDEI), cilostazol (CLZ) in the treatment of ovarian ischemia reperfusion induced damage (OIR). METHODS Rats were divided into five groups; sham, OIR group; CLZ (5, 10, 20 mg/kg) was given orally with induced OIR. Different biochemical parameters were detected such as total anti-oxidant capacity (TAC), reduced glutathione (GSH), malondialdehyde (MDA), cyclic adenosine monophosphate (cAMP), sirtuin1 (SIRT1), toll like receptor 4 (TLR4), nuclear factor kappa b (NF-κB) and tumor necrosis factor alpha (TNFα). In addition, histopathological features, ovarian weight changes and casapse3 immunoexpression were detected. RESULTS Data revealed significant increase in ovarian weight changes, MDA, TLR4, TNFα, NF-κB and caspase 3 expressions in OIR induced group. Moreover, OIR group had histopathological features of ovarian damage with depletion of cAMP, SIRT1, TAC and GSH. CONCLUSION CLZ could ameliorate OIR-induced damage due to PDE inhibition, anti-oxidant, anti-inflammatory and anti-apoptotic properties with modulation of TLR4/NF-κB/TNFα and cAMP/SIRT1 signaling pathways.

Abstract
AIM To investigate the protective effect of octreotide and lanreotide on ovarian damage in experimental ovarian ischemia-reperfusion injury. METHODS Fifty-six rats were separated into seven groups; group 1: sham group, group 2: surgical control group with 3-h torsion and detorsion, group 3: 0.02 mg/kg s.c. octreotide 30 min before 3-h torsion, group 4; octreotide just after detorsion for 7 days, group 5: octreotide 30 min before torsion and just after detorsion for 7 days, group 6: single time 20 mg/kg s.c. lanreotide before torsion, group 7: single time lanreotide just after detorsion. RESULTS All histopathological scores except congestion were significantly lower in group 1 than other groups. In addition, hemorrhage (group 2 vs 4: P < 0.05), degeneration (group 2 vs 4: P < 0.05, group 2 vs 5: P < 0.01 and group 2 vs 6: P < 0.05) and total damage score (group 2 vs 4: P < 0.05, group 2 vs 5: P < 0.05, group 2 vs 6: P < 0.05 and group 2 vs 7: P < 0.05) were significantly lower than other groups. Moreover, ovarian tissue total oxidant status and oxidative stress index levels were significantly decreased in groups 5 (both P < 0.05) and 7 (both P < 0.05) when compared to group 2. Furthermore, tissue levels of peroxynitrite were significantly higher in group 2 than groups 1, 3 and 5 (all P < 0.05). CONCLUSIONS Octreotide and lanreotide have a protective role against ischemia-reperfusion damage in rat torsion detorsion model by improving histopathological and biochemical findings including tissue levels of total oxidant status, oxidative stress index and peroxynitrite.

Abstract
Abstract
Superoxide dismutase 1 suppresses oxidative stress within cells by decreasing the levels of superoxide anions. A dysfunction of the ovary and/or an aberrant production of sex hormones are suspected causes for infertility in superoxide dismutase 1-knockout mice. We report on attempts to rescue the infertility in female knockout mice by providing two antioxidants, ascorbic acid and/or coenzyme Q10, as supplements in the drinking water of the knockout mice after weaning and on an investigation of their reproductive ability. On the first parturition, 80% of the untreated knockout mice produced smaller litter sizes compared with wild-type mice (average 2.8 vs 7.3 pups/mouse), and supplementing with these antioxidants failed to improve these litter sizes. However, in the second parturition of the knockout mice, the parturition rate was increased from 18% to 44–75% as the result of the administration of antioxidants. While plasma levels of progesterone at 7.5 days of pregnancy were essentially the same between the wild-type and knockout mice and were not changed by the supplementation of these antioxidants, sizes of corpus luteum cells, which were smaller in the knockout mouse ovaries after the first parturition, were significantly ameliorated in the knockout mouse with the administration of the antioxidants. Moreover, the impaired vasculogenesis in uterus/placenta was also improved by ascorbic acid supplementation. We thus conclude that ascorbic acid and/or coenzyme Q10 are involved in maintaining ovarian and uterus/placenta homeostasis against insults that are augmented during pregnancy and that their use might have positive effects in terms of improving female fertility.

Abstract
INTRODUCTION Etanercept has been widely used in autoimmune diseases for blocking tumor necrosis factor α (TNF-α), which is an inflammatory cytokine. The anti-apoptotic and anti-inflammatory effects of etanercept against ischemia/reperfusion (I/R) injury have been shown for several tissues in rat studies, but to the best of our knowledge, there are no reports on its protective effects following similar injury in ovarian tissue. The aim of this study was to investigate whether etanercept has beneficial effects on ovarian I/R injury, as well as on ovarian reserve. MATERIAL AND METHODS Twenty-four rats were randomly divided into four groups (n = 6/group): sham (laparotomy only); sham + etanercept; I/R; and I/R + etanercept. Ischemia was induced for 3 h by twisting the ovary, and 24 h after detorsion the ovarian tissues were collected to evaluate histopathologic changes, glutathione (GSH), malondialdehyde (MDA), myeloperoxidase (MPO), and superoxide dismutase (SOD) concentrations for oxidative stress, 8-hydroxy-2'-deoxyguanosine (8-OHdG) for DNA damage, caspase-3 activity for apoptosis and ovarian follicle counts. To measure anti-Mullerian hormone (AMH), serum samples were drawn before and after surgery. RESULTS Tissue GSH and SOD levels were significantly higher, while MDA and MPO levels were significantly lower in the I/R + etanercept group than in the I/R group (p < 0.05, p < 0.01, respectively). Tissue 8-OHdG and caspase-3 activity were significantly lower in the I/R+etanercept group than in the I/R group (p < 0.05, p < 0.01, respectively). Preoperative and postoperative AMH levels were compared and there was a significant reduction in the I/R and I/R + etanercept groups (p < 0.001, p < 0.001). The reduction of AMH in the I/R + etanercept group was significantly lower than in the I/R group. The primordial, preantral and small antral follicle numbers were also significantly higher in the I/R + etanercept group compared to the I/R group (p < 0.001, p < 0.001, p < 0.005, respectively). CONCLUSIONS Etanercept attenuated inflammation and related oxidative stress and also helped to preserve ovarian reserve following ovarian I/R damage.

Abstract
Ovarian torsion is a dangerous gynecological emergency condition. Early diagnosis of this case is necessary to preserve the function of the ovaries and fallopian tubes and prevent further damage. Ovarian torsion means complete or partial rotation of the adnexa with ischemia followed by reperfusion period. Ovarian torsion affects 2%-15% of patients who have surgical treatment of adnexal masses. We investigated the effect of pioglitazone (PIO) on induced ovarian ischemia reperfusion (OIR). PIO (10, 30 mg/kg) was administered orally in the presence or absence of induced OIR. We measured ovarian tissue malondialdehyde (MDA), total nitrites (NOx), reduced glutathione (GSH), heme-oxygenase 1 (HO-1), and gene expressions of peroxisome proliferator activated receptor gamma (PPARγ), tumor necrosis factor alpha (TNFα), inducible nitric oxide synthase (iNOS) and endothelial nitric oxide synthase (eNOS). Moreover, expression of p53 and histopathological changes were also evaluated. Results showed increase in the ovarian tissue levels of MDA and NOx and gene expressions of p53, TNFα, and iNOS in the induced OIR group. The induced OIR group showed the histopathological changes associated with cell injury, marked ovarian edema, hemorrhage and congestion. In addition, there was reduction in the GSH, HO-1 levels and PPARγ, eNOS gene expressions. PIO was able to reduce these induced OIR changes to levels insignificant from control group. This protective effect of PIO may be attributed to its PPARγ agonist effect, anti-inflammatory, anti-apoptotic and anti-oxidant properties.

Abstract
Background: Apigenin is a plant-derived compound belonging to the flavone class, which possess antioxidant, free-radical-scavenging and anti-inflammatory properties. Aims: To address the effects of apigenin on serum anti-mullerian hormone levels, tissue oxidative stress parameters and histopathological changes in ovarian ischemia/reperfusion injury. Study Design: Animal experiment. Methods: Twenty-eight female Wistar albino rats were randomly separated into four sections: Sham operation (group 1), ischemia/reperfusion plus saline (group 2), ischemia/reperfusion plus dimethyl sulfoxide (group 3) and ischemia/reperfusion plus apigenin (group 4). In all ischemia/reperfusion groups, a bilateral adnexal 3-h period of ischemia was performed, followed by 3-h of reperfusion. A single dose of 15 mg/kg apigenin was given intraperitoneally 60 min before reperfusion in group 4. After 3-h of reperfusion, both ovaries were removed, and blood samples were collected. The main outcome measures were serum anti-mullerian hormone levels, ovarian tissue malondialdehyde, total nitric oxide, Cu/Zn superoxide dismutase, catalase and glutathione levels and histopathological damage scores. Results: The ovarian tissue nitric oxide level was significantly lower, and the glutathione level was significantly higher in group 4 compared with groups 2 and 3. There was no significant difference in anti-mullerian hormone levels among the three ischemia/reperfusion groups. The histopathological damage score was lower in group 4 than in groups 2 and 3 (p>0.05). Conclusion: Administration of apigenin has no significant protective effect on ovarian reserve and tissue damage in ovarian ischemia/reperfusion injury.

Abstract
PURPOSE Ovarian torsion must be diagnosed and treated as much early as possible. The aim of the present study was to investigate effects of intraperitoneal administration of nimodipine on ischemia-reperfusion injury in ovaries. METHODS Thirty healthy male Wistar rats weighing approximately 250g were randomized into six experimental groups (n=5): Group Sham: The rats underwent only laparotomy. Group I: A 3-h ischemia only. Group I/R: A 3-h ischemia and a 3-h reperfusion. Group I/Nimodipine: A 3-h ischemia only and 1mg/kg intraperitoneal administration of nimodipine 2.5h after induction of ischemia. Group I/R/Nimodipine: A 3-h ischemia, a 3-h reperfusion and 1mg/kg intraperitoneal administration of nimodipine 2.5h after induction of ischemia. RESULTS Nimodipine treated animals showed significantly ameliorated development of ischemia and reperfusion tissue injury compared to those of other groups (P<0.05). The significant higher values of SOD, tGSH, GPO, GSHRd and GST were observed in I/R/Nimodipine animals compared to those of other groups (P<0.05). The damage indicators (NOS, MDA, MPO and DNA damage level) were significantly lower in I/R/Nimodipine animal compared to those of other groups (P<0.05). CONCLUSIONS Intraperitoneal administration of nimodipine could be helpful in minimizing ischemia-reperfusion injury in ovarian tissue exposed to ischemia.

Abstract
Aim The purpose of this study was to investigate the protective effect of honokiol on experimental ischemia/reperfusion injury of rat ovary. Materials and methods A total of 40 female Wistar albino rats were used in this study. The rats were divided into five groups as follows: sham (Group I), torsion (Group II), torsion + detorsion (Group III), torsion + detorsion + saline (Group IV), and torsion + detorsion + honokiol (Group V). Bilateral adnexa in all the rats except for those in the sham group were exposed to torsion for 3 hours. The rats in Group IV were administered saline, whereas the rats in Group V were administered honokiol by intraperitoneal route 30 minutes before detorsion. Tissue and plasma concentrations of malondialdehyde and nitric oxide were determined. Ovarian tissue was histologically evaluated. Data analyses were performed by means of Kruskal–Wallis test and Mann–Whitney U-test (Bonferroni correction) in SPSS 15.0 (Statistical Package for Social Sciences; SPSS Inc., Chicago, IL, USA). Results The torsion and detorsion groups had higher scores in vascular congestion, hemorrhage, and inflammatory cell infiltration compared with the sham group (P<0.005). In addition, total histopathological scores were significantly higher in the torsion and detorsion groups compared with the sham group (P<0.005). A significant reduction was observed in hemorrhage, inflammatory cell infiltration, and cellular degeneration scores, of all histopathological scores, in the honokiol group (P<0.005). Ovarian tissue concentrations of malondialdehyde were significantly higher in the torsion and detorsion groups compared with the sham and honokiol groups (P<0.005). Ovarian tissue concentrations of nitric oxide, on the other hand, were significantly higher in the torsion group compared with the sham, saline, and honokiol groups (P<0.005). Conclusion Honokiol has a beneficial effect on ovarian torsion-related ischemia/reperfusion injury.

Abstract
Objective. This study aims to evaluate whether alpha-lipoic acid and/or coenzyme Q10 can protect the prepubertal ovarian tissue from ischemia-reperfusion injury in an experimental rat model of ovarian torsion. Materials and Methods. Forty-two female preadolescent Wistar-Albino rats were divided into 6 equal groups randomly. The sham group had laparotomy without torsion; the other groups had torsion/detorsion procedure. After undergoing torsion, group 2 received saline, group 3 received olive oil, group 4 received alpha-lipoic acid, group 5 received coenzyme Q10, and group 6 received both alpha-lipoic acid and coenzyme Q10 orally. The oxidant-antioxidant statuses of these groups were compared using biochemical measurement of oxidized/reduced glutathione, glutathione peroxidase and malondialdehyde, pathological evaluation of damage and apoptosis within the ovarian tissue, and immunohistochemical assessment of nitric oxide synthase. Results. The left ovaries of the alpha-lipoic acid + coenzyme Q10 group had significantly lower apoptosis scores and significantly higher nitric oxide synthase content than the left ovaries of the control groups. The alpha-lipoic acid + coenzyme Q10 group had significantly higher glutathione peroxidase levels and serum malondialdehyde concentrations than the sham group. Conclusions. The combination of alpha-lipoic acid and coenzyme Q10 has beneficial effects on oxidative stress induced by ischemia-reperfusion injury related to ovarian torsion.

Abstract
AIMS To investigate a trend for adnexal torsion direction and factors that may be associated with direction. METHODS We retrospectively reviewed the medical files of all women who underwent exploratory laparoscopy for suspected ovarian torsion in our center from August 2010 to December 2012. RESULTS Fifty-five women had laparoscopically proven torsion. Medial rotation, defined as clockwise rotation of the left adnexa or counterclockwise rotation of the right adnexa, with the proximal (lateral) segment of the infundibulopelvic ligament serving as the referral point was noted in most cases (n = 47, 85.5%). There was no statistically significant difference between the medial and lateral rotation groups. However, the proportion of pregnant women and mean parity were significantly higher in the lateral compared to the medial rotation group: 62.5 vs. 19.1%, p = 0.009 and 1.1 ± 1.2 vs. 0.1 ± 0.4, p < 0.001. Medial torsion was present in 64.3% of pregnant women vs. 92.7% of nonpregnant women, p = 0.009. CONCLUSION The direction of ovarian or adnexal torsion is usually medially rotated, opposite to the psoas muscles and the great blood vessels on the same side. However, surgeons should be aware of an increased rate of lateral rotation among pregnant women.

Abstract
BACKGROUND/AIMS Ovarian torsion is a common cause of local ischemic damage, reduced follicular activity and infertility. Platelet-rich plasma (PRP) contains growth factors with demonstrated cytoprotective properties; so we evaluated PRP efficacy in a rat ischemia/reperfusion (I/R) model. METHODS Sixty adult female Sprague-Dawley albino rats were randomly assigned to 6 groups of 8 animals each: Sham, Ischemia, I/R, Sham + PRP, I + PRP and I/R + PRP; and the remaining 12 used to prepare PRP. Ischemia groups were subjected to bilateral adnexal torsion for 3 h, while I/R and I/R + PRP groups received subsequent detorsion for 3 h. Intraperitoneal PRP was administered 30 min prior to ischemia (Ischemia + PRP) or reperfusion (I/R + PRP). RESULTS Total oxidant status (TOS), oxidative stress index (OSI) and total ovarian histopathological scores were higher in Ischemia and I/R groups than in the Sham group (p < 0.05). PRP decreased mean TOS, OSI and histopathological scores in I + PRP and I/R + PRP groups compared to the corresponding Ischemia and I/R groups (p < 0.001). There was a strong correlation between total histopathological score and OSI (r = 0.877, p < 0.001). Peritoneal vascular endothelial growth factor was significantly higher in PRP-treated groups than corresponding untreated groups (p < 0.05). CONCLUSION PRP is effective for the prevention of ischemia and reperfusion damage in rat ovary.

Gynecol Obstet Invest 2015; 81:262-6. [PMID: 26336916 DOI: 10.1159/000437422] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2014] [Accepted: 07/05/2015] [Indexed: 11/19/2022]
Abstract
OBJECTIVE To study whether sonographic findings suggestive of ovarian stromal edema are associated with tissue ischemia in patients with adnexal torsion. METHODS A study of 79 patients with adnexal torsion was performed. Patients were divided into an ischemic group, in which the twisted adnexa were seen as blue or black, and a non-ischemic group, in which the adnexa retained normal color and appeared viable. Clinical and ultrasonographic findings, specifically the presence of ultrasonographic signs suggestive of ovarian stromal edema, were compared between the two groups. RESULTS Of the 79 patients with torsion, in 44 (55.7%) the adnexa appeared ischemic at surgery. The presence of ischemia was not associated with age, pregnancy, duration of pain, vomiting or findings at physical examination. There was no significant difference between the ischemic and the non-ischemic group in the proportion of patients with signs of ovarian stromal edema (59 vs. 40%, p = 0.11), in the proportion of patients with absent/diminished stromal Doppler flow (36 vs. 28%, p = 0.12%) or in the proportion of patients with both signs of stroma edema and absent/diminished stromal Doppler flow (20 vs. 12%, p = 0.36). CONCLUSION Ultrasonographic signs of ovarian stromal edema do not assist in differentiating between ischemic and non-ischemic adnexal torsion.

Abstract
BACKGROUND/AIMS To investigate the effectiveness of controlled reperfusion (CR) on ovarian tissue malondialdehyde, total glutathione and 8-hydroxyguanine levels and infertility rates in a rat model of induced ischemia-reperfusion (I/R) injury with unilateral oophorectomy. METHODS A total of 135 adult female albino Wistar rats were divided into 9 groups (n = 15 for each group): unilateral ovariectomy + ovarian I/R (OIR), unilateral ovariectomy alone (OEG), a sham operation group (SG), and unilateral ovariectomy + CR performed at different intervals (the clips were released 10 times for 10, 8, 6, 4, 2 or 1 s and closed again 10 times for 10, 8, 6, 4, 2 or 1 s; OCR-1-6, respectively). Five rats from each group were sacrificed, and their ovaries were removed. RESULTS Higher ovarian tissue malondialdehyde and 8-hydroxyguanine levels and lower ovarian tissue total glutathione levels were found in the OIR group compared with the SG, OEG and OCR-4-6 groups. The number of rats giving birth during the study period was found to be similar among the SG (n = 8), OEG (n = 8) and OCR-6 (n = 7) groups. CONCLUSION These results suggest that sterility and ovarian oxidative stress caused by I/R injury decreases in parallel to the shortening of CR duration.

Abstract
AIM The aim of this study is to evaluate the diagnostic value of serum oxidative stress marker levels (ischemia-modified albumin, IMA; malondialdehyde, MDA) and total oxidant status (TOS), total antioxidant status (TAS) and oxidative stress index (OSI) levels that occur in ovarian torsion and to determine the threshold value of these markers in the diagnosis of ovarian torsion. METHODS In this prospective case-control study, 34 women (the study group) with acute pelvic pain (20 with and 14 without ovarian torsion) and 40 control subjects were included. The diagnosis of ovarian torsion was confirmed with laparoscopy in all cases. Preoperative serum samples were collected in the study group. Serum oxidative stress marker levels (IMA and MDA) and TOS, TAS and OSI levels were measured. RESULTS Serum MDA, TOS and IMA concentrations were significantly higher in women with ovarian torsion than in the healthy control group. However, serum TAS, TOS and OSI concentrations were significantly higher in women without ovarian torsion than within the healthy control group. Only IMA significantly distinguished patients with or without ovarian torsion. The best IMA value, according to the receiver operating characteristic curve, was 0.7045 absorbance units, with 90.00% sensitivity and 92.31% specificity. The patients in the ovarian torsion group had significantly lower serum TAS and OSI levels compared with patients without ovarian torsion. CONCLUSION The elevated serum IMA levels with high sensitivity-specificity values observed in women with ovarian torsion seem to have a potential role as a serum marker in the preoperative diagnosis of ovarian torsion in emergency settings.
