Abstract
OBJECTIVE Ovarian torsion is a gynecological disorder that causes ischemia-reperfusion injuries in the ovary. Our study investigated berberine's short- and long-term effects on ovarian ischemia-reperfusion injuries. METHODS This study included 28 Wistar albino female rats weighing 180 to 220 g, which were divided into four groups: sham (S), torsion/detorsion (T/D), torsion/ detorsion+single dose berberine (T/D+Bb), and torsion/detorsion+15 days berberine (T/D+15Bb). The torsion and detorsion model was applied in all non-sham groups. In the T/D+Bb group, a single dose of berberine was administered, while in the T/D+15Bb group, berberine was administered over a period of 15 days. After the rats were euthanized, their ovaries were excised. The left ovaries were used for histopathologic evaluation, which included ovarian injury scoring and follicle count, while the right ovaries were used for biochemical analyses (tissue transforming growth factor-β [TGF-β] and alpha-smooth muscle actin [α-SMA] levels). RESULTS The histopathologic evaluation scores for the ovaries were significantly lower in the T/D+B group (p<0.05) and the T/D+15B group (p<0.005) than in the T/D group. The follicle counts in the T/D group were lower than those in both the sham and treated groups (p<0.005). The TGF-β levels were significantly lower in the T/D+15B group (p<0.005), whereas the α-SMA levels did not show a significant difference. CONCLUSION Both short- and long-term berberine use could potentially have therapeutic effects on ovarian torsion. Long-term berberine use exhibited anti-inflammatory effects by reducing TGF-β levels, thereby preventing ischemia-reperfusion injuries. Therefore, we suggest that long-term berberine use could be beneficial for ovarian torsion.

Abstract
Ischemia/reperfusion (I/R) induced ovarian damage is caused by various diseases such as ovarian torsion, ovarian transplantation, cardiovascular surgery, sepsis, or intra-abdominal surgery. I/R-related oxidative damage can impair ovarian functions, from oocyte maturation to fertilization. This study investigated the effects of dexmedetomidine (DEX), which has been shown to exhibit antiapoptotic, anti-inflammatory, and antioxidant effects, on ovarian I/R injury. We designed four study groups: group 1 (n = 6): control group; group 2 (n = 6): only DEX group; group 3 (n = 6): I/R group; group 4 (n = 6): I/R + DEX group. Then, ovarian samples were taken and examined histologically and immunohistochemically, and tissue malondialdehyde (MDA) and glutathione (GSH) levels were measured. In the I/R group MDA levels, caspase-3, NF-κB/p65, 8-OHdG positivity, and follicular degeneration, edema, and inflammation were increased compared to the control group (p = 0.000). In addition, GSH levels were significantly decreased in the I/R group compared to the control group (p = 0.000). On the other hand, in the I/R + DEX treatment group MDA levels, caspase-3, NF-κB/p65, 8-OHdG positivity, follicular degeneration, edema, and inflammation findings were decreased than in the I/R group (p = 0.000, p = 0.005, p = 0.005, p = 0.001, p = 0.005, respectively). However, GSH levels increased significantly in the I/R + DEX treatment group compared to the I/R group (p = 0.000). DEX protects against ovarian I/R injury through antioxidation and by suppressing inflammation and apoptosis.

Abstract
Agents to reduce the gonadotoxic effects of chemotherapeutics are still under investigation. In this context, we aimed to investigate the protective effect of sildenafil against chemotherapeutic-induced gonadotoxicity in a rat model. A total of 62 female rats were divided into eight groups as control, sildenafil (1.4 mg/kg, orally), doxorubicin (3 mg/kg, i.p.), cisplatin (5 mg/kg, i.p.), cyclophosphamide (200 mg/kg, i.p.), doxorubicin+sildenafil, cisplatin+sildenafil, and cyclophosphamide+sildenafil (1.4 mg/kg orally sildenafil in addition to the same dose of chemotherapeutics). The groups were compared in terms of follicle count, ovarian size, and anti-müllerian hormone (AMH) levels. Use of sildenafil with cyclophosphamide was effective only in preserving primary follicle count (p = 0.026) and had no significant change in the secondary follicle count, ovarian size, or AMH level. Adding sildenafil to cisplatin had a significant protective effect on primary follicle count (p = 0.011), secondary follicle count (p = 0.009), and ovarian size (p = 0.001), but this effect could not be demonstrated at AMH level. Sildenafil was not effective on any parameter in the doxorubicin group. Sildenafil may be effective in reducing the gonadotoxicity associated with the use of cisplatin and cyclophosphamide.

Abstract
The aim of this experimental animal study was to investigate the histopathological and biochemical efficacy of trimetazidine (TMZ) in decreasing ovary damage in an ovary ischaemia/reperfusion (I/R) model in the rat. A total of 35 Wistar albino female rats were randomly separated into five groups, n = 7 per group: Group 1: Sham (S) was only given a laparotomy procedure. Group 2: Ischaemia (I) group with 2-hour ischaemia using a vascular sutur. Group 3: Ischaemia/Reperfusion (I/R) group with 2 hour ischaemia and 2-hour reperfusion. Group 4: Sham + 10 mg/kg orally TMZ (S + TMZ). Group 5: I/R + 10 mg/kg oral TMZ (I/R + TMZ) group with 2 hours ischaemia and 2 hours reperfusion after the administration orally 10 mg/kg oral TMZ. Two daily doses of TMZ were orally administered to Group 4 (S + TMZ) and Group 5 (I/R + TMZ) for three days. TMZ significantly decreased vascular congestion, haemorrhage, and polymorphonuclear leukocyte infiltration in group 5 compared to group 3 (p < .05). Despite TMZ decreased the malondialdehyde, total oxidant status, and oxidative stress index values, these decreases were not statistically significant (p > .05). TMZ which is an antioxidant agent can efficiently prevent in I/R damage in rat ovaries but further studies are necessary in order to implement it in the clinical settings.IMPACT STATEMENTWhat is already known on this subject? Adnexial torsion is the most common gynecological emergency and there are no specific clinical, laboratories, or radiological findings for adnexal torsion. Unfortunatelly, the currently accepted treatment is adnexal detorsion. Cytoprotective effects of Trimetazidine (TMZ), an antianginal drug, are well-defined and it has been demonstrated to improve oxidative stress markers and limits membrane damage induced by reactive oxygen species and protects tissues from free radicals with its antioxidant effects. The aim of this study is to investigate the effects of TMZ in experimentally induced adnexal torsion in rats and to investigate possible effects in maintaining ovarian reserve to prevent I/R damage or reperfusion damage.What do the results of this study add? Our study showed that TMZ significantly decreased vascular congestion, haemorrhage, and PMNL infiltration. TMZ decreased the malondialdehyde, total oxidant status, and the oxidative stress index values, but these decreases were not statistically significant.What are the implications of these findings for clinical practice and/or further research? Although various antioxidant drugs and chemicals have been used to protect the ovaries against I/R damage, they have not been demostrated to prevent it completely. TMZ, an antioxidant efficacy agent, has been shown to prevent ovarian I/R damage by suppressing inflammation in terms of histopathological parameters. Further studies involving a greater number of experimental animals are required before using TMZ for the treatment of humans with I/R damage in the clinical setting.

Abstract
PURPOSE The ischemia/reperfusion (I/R) injury of ovaries in adnexal torsion may have inadvertent consequences. Many agents have been studied in terms of their ability to prevent reperfusion damage to ovaries in suspected cases. In this study, folic acid, known to have antioxidative properties, was investigated to determine whether it played a role in the prevention of I/R damage in a rat ovarian torsion model. METHODS In this experimental study, 40 female adult Wistar-Albino rats were randomly divided into five groups as control, ischemia, I/R, Fol2 (2 mg/kg folic acid), and Fol4 (4 mg/kg folic acid). In the Fol2 and Fol4 groups, folic acid was intraperitonelly administered 30 min before reperfusion. Blood samples were obtained from the tails of each rat at the second hour of reperfusion. RESULTS The total oxidant status (TOS), total antioxidant status, cystatin C and folic acid levels of the five groups were investigated. Folic acid in 2 mg/kg dose could moderately increase the serum folic acid concentration (15.75-19.95 ng/ml, p < 0.05), reduce the level of cystatin C (0.18-0.12 μg/L, p < 0.05), and had a tendency to improve the oxidative stress injury (OSI: 76.05-33.06, p > 0.05), although there was no statistical difference in TOS levels (p = 0.07). Folic acid in 4 mg/kg dose, could significantly increase the serum folic acid concentration (15.75-37.65 ng/ml). However, it did not significantly reduce the level of cystatin C (0.18-0.19 μg/L, p > 0.05), and did not improve oxidative stress injury (76.05-130.58, p > 0.05). CONCLUSION Folic acid in 2 mg/kg dose might improve the ovarian I/R injury though this was not statistically significant. Further studies are required to reach a definitive conclusion about the protective effect of folic acid in I/R injury.

Abstract
Sildenafil, approved two decades ago, is the inhibitor of phosphodiesterase 5 (PDE5). First of all, it was designated for angina pectoris, but soon it showed a wonderful efficacy in erectile dysfunction (ED) and then pulmonary arterial hypertension (PAH). Due to the distribution of phosphodiesterase (PDE) in almost all organs, maybe it effects other diseases. Hence, a great number of investigations began to understand the role of PDEi in different organs. Preliminary research on sildenafil in cell culture and animal models has yielded promising results. Soon, a greater number of animal researches and clinical trials joined them. The results disclosed sildenafil can have beneficial effects in each organ such as heart, liver, kidney, brain, and intestines. Furthermore, it has significantly improved the prognosis of organ ischemia in various animal models. Clinical trials in several diseases, such as recurrent spontaneous miscarriage, fatty liver disease, bronchopulmonary dysplasia (BPD), heart failure, and premature ejaculation (PE) brought promising results. Although some clinical trials are available on the effects of sildenafil on various diseases, further studies on humans are needed to consolidate the ultimate effects of sildenafil. The aim of this review was to describe the effects of sildenafil on each organ and explain its mechanisms of action. Further, other PDE inhibitors such as tadalafil and vardenafil have been briefly discussed in parts of this review.

Abstract
AIM An experimental study was performed to evaluate the effects of Vardenafil on ischemia-reperfusion (I/R) injury in an experimental volvulus model by histochemical and biochemical methods. MATERIALS AND METHODS Thirty-five male Wistar rats were divided in five groups (n = 7). In Group 1, a 5 cm segment of small intestine 2 cm proximal to cecum was excised to have a control group. In the second group, 5 cm segment of small intestine 2 cm proximal to cecum was rotated 360° clockwise direction and sutured with 4/0 polyglactin to generate an experimental model of volvulus. At the end of 2 h of ischemia, the same intestinal segment was sampled. In group 3, after achieving ischemia similar to group 2, two hours of reperfusion injury was obtained by removing the sutures. Rats in Group 4 received vardenafil after 1.5 h of ischemia and then 2 h of reperfusion. And finally, in Group 5, vardenafil was administered 2 h before laparotomy and 5 cm of intestine was removed without I/R injury. Intestinal segments were evaluated for total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI) with biochemical and histopathological analysis. RESULTS Serum TOS levels and OSI were not significantly different between groups (p = 0.910, P = 0,43 respectively). The serum TAS level was decreased in group 3 as compared to vardenafil groups 4 and 5, without a statistical significance (p = 0.428). In histopathologic analysis, we found that vardenafil, partially reduced I/R injury. The villus structure was preserved but, congestion and inflammation were moderate. CONCLUSION Vardenafil partially reduced I/R injury histopathologically on intestine. Our study shows that it does not have statistically antioxidant effect on intestinal I/R injury in experimental model of volvulus. However, effects of vardenafil in I/R injury of liver, kidney, heart, testis, over and brain which were cited in literature were not confirmed with I/R injury on intestine.

Abstract
AIM Ovarian torsion is a rare but an important reason of acute lower abdominal pain in women and associated with serious morbidity and mortality, if not treated promptly. The aim of this study was to evaluate the effects of an antitumor necrosis factor-α antibody on ovarian torsion in a rat model of ischemia-reperfusion (I/R) injury. METHODS Forty female Wistar Albino rats were used in the present study. The rats were randomly divided into four groups: group I (sham), group II (I/R), group III (I/R + isotonic saline) and group IV (I/R + adalimumab). The I/R model was induced by torsion of both ovaries. Immunohistochemical staining for interleukin-1β (IL-1β), nuclear factor-κB (NF-κB), and inducible nitric oxide synthase was performed. Tissue and serum oxidative stress markers in conjunction with apoptotic index (AI) with the terminal deoxynucleotidyl transferase dUTP nick end labeling method were also calculated. RESULTS Tissue total oxidant status, oxidative stress index and nitric oxide values were significantly decreased, and tissue total antioxidant status was found to be increased in group IV. Inflammation, vascular congestion and hemorrhagia were significantly lower in adalimumab-treated group. Serum oxidative stress markers and tissue malondialdehyde levels did not differ in study groups. The AI was significantly increased in groups 2 and 3. Adalimumab treatment significantly decreased the AI. CONCLUSION Adalimumab therapy in rats attenuated I/R induced ovarian injury, possibly suppressing inflammation, inhibiting oxidative stress, and altering apoptotic pathways.

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.

J Pediatr Surg 2017; 52:492-497. [PMID: 27836358 DOI: 10.1016/j.jpedsurg.2016.10.006] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/17/2016] [Revised: 08/25/2016] [Accepted: 10/11/2016] [Indexed: 12/21/2022]
Abstract
BACKGROUND The present study aimed to investigate the effects of hydrogen rich saline solution (HRSS) in a rat model of ovarian ischemia-reperfusion injury. METHODS Thirty-six female Wistar-albino rats were grouped randomly, into six groups of six rats. The groups were classified as: sham (S), hydrogen (H), torsion (T), torsion/detorsion (TD), hydrogen-torsion (HT), and hydrogen-torsion/detorsion (HTD). Bilateral adnexal torsion was performed for 3h in all torsion groups. HRSS was given 5ml/kg in hydrogen groups intraperitoneally. Malondialdehyde (MDA) and glutathione-S-transferase (GST) levels were measured in both the plasma and tissue samples. Tissue sections were evaluated histopathologically, and the apoptotic index was detected by TUNEL assay. The results were analyzed by Kruskal-Wallis and Pearson chi-square tests using computer software, SPSS Version 20.0 for Windows. RESULTS The MDA levels were higher and GST levels were lower in the torsion and detorsion groups when compared to other groups, but the differences were insignificant (P>0.05). The MDA levels were lower and GST levels were higher in the HT and HTD groups compared with the T and TD groups (P>0.05). Follicular injury, edema, vascular congestion, loss of cohesion and apoptotic index were higher in the torsion groups but decreased in the groups that received HRSS. CONCLUSIONS According to histopathological and biochemical examinations, HRSS is effective in attenuating ischemia-reperfusion induced ovary injury.

Mostafa T. Useful Implications of Low-dose Long-term Use of PDE-5 Inhibitors. Sex Med Rev 2016; 4:270-284. [PMID: 27871960 DOI: 10.1016/j.sxmr.2015.12.005] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2015] [Revised: 12/24/2015] [Accepted: 12/24/2015] [Indexed: 02/08/2023]
Abstract
INTRODUCTION Phosphodiesterase type 5 (PDE-5) hydrolyzes cyclic guanylate monophosphate (cGMP) specifically to 5' GMP, promoting successful corporeal vascular relaxation and penile erection during sexual stimulation. Oral PDE-5 inhibitors such as sildenafil, vardenafil, tadalafil, and avanafil have provided noninvasive, effective, well-tolerated treatment for erectile dysfunction (ED) patients and, at the same time, stimulated both academic and clinical interests. Lately, some oral PDE-5 inhibitors were released as low-dose preparations with the concept of potential daily administration and long-term use. AIM To highlight the possible potential implications of low-dose long-term use of PDE-5 inhibitors. METHOD A systematic review was carried out until December 2015 based on a search of all concerned articles in MEDLINE, medical subjects heading (MeSH) databases, Scopus, The Cochrane Library, EMBASE, and CINAHL databases without language restriction. Key words used to assess the outcome and estimates for concerned associations were: PDE-5 inhibitors; erectile dysfunction; low-dose; long-term; sildenafil; tadalafil; vardenafil; avanafil. MAIN OUTCOME MEASURES Demonstrating different implications for low-dose long-term use of PDE-5 inhibitors. RESULTS Low-dose and/or long-term use of PDE-5 inhibitors was shown to put forth beneficial sound effects in different medical implications with potentials that could be extended for different utilities. These implications included sexual, urogenital, cardiovascular, pulmonary, cutaneous, gastrointestinal, and reproductive, as well as neurological disorders. However, it is evident that most potential appliances were carried out experimentally on preclinical studies with off-label indications. CONCLUSION Making use of and exploring low-dose and/or long-term use of several PDE-5 inhibitors for their possible implications seem to be valuable in different medical disorders. Increased knowledge of the drug characteristics, comparative treatment regimens, optimal prescribing patterns, and well-designed clinical trials are needed before these agents can be recommended for use.
