Abstract
Background Testicular torsion causes ischemic injury, and torsion causes reperfusion injury. Aim Evaluating the role of augmenter of liver regeneration (ALR) in testicular ischemia and ischemia/reperfusion injury. Materials and Method(s) Seventy-eight (78) healthy Wistar albino male rats were randomly divided into four groups; control (C) (n = 6), sham (S) (n = 24), torsion (T) (n = 24), and torsion/detorsion (T/D) (n = 24). S, T, and T/D groups were divided into four subgroups (n = 6) as 1st, 2nd, 3rd, and 4th hours. Blood, tissue ALR, and histology analyses were performed between groups and subgroups. Results The increase in plasma ALR values at the 3rd and 4th hours compared to the 1st hour in the T group were significant (P < 0.01, P < 0.001, respectively). In the T/D group, a significant increase was observed in plasma ALR values at the 3rd and 4th hours compared to the 1st hour (P < 0.05, P < 0.001, respectively). Plasma ALR values at the 1st, 2nd, 3rd, and 4th hours were higher in the T and T/D groups than in the C group (P < 0.001, P < 0.05, respectively). Plasma ALR values were higher in the T group at the 1st, 2nd, 3rd, and 4th hours than in the S group (P < 0.05). A significant increase was observed in tissue ALR at the 3rd and 4th hours than at the 1st hour in the T group (P < 0.05, P < 0.001, respectively). A significant increase was observed in tissue ALR at the 3rd and 4th hours than in the 1st hour in the T/D group (P < 0.05, P < 0.001, respectively). Discussion ALR in plasma and testicular tissue has a potential role in the early diagnosis of testicular torsion and in predicting the prognosis of T and T/D.

Abstract
Background Oxidative damage is critical in the pathogenesis of ovarian ischaemia/reperfusion (I/R) injury, and statins have been reported to exert antioxidant activity. However, the role of VCAM-1 and xanthine oxidase (XO)/uric acid (UA) in ovarian I/R injury is not known. Also, whether or not atorvastatin exerts antioxidant activity like other statins is unclear. Objectives This study investigated the involvement of VCAM-1 and XO/UA in ovarian I/R injury and the likely protective role of atorvastatin. Methods Forty female Wistar rats were randomized into sham-operated, ischaemia, ischaemia/reperfusion (I/R), ischaemia and atorvastatin, and I/R and atorvastatin. Results In comparison with the sham-operated group, atorvastatin blunted ischaemia and I/R-induced distortion of ovarian histoarchitecture and follicular degeneration. Also, atorvastatin alleviated ischaemia and I/R-induced rise in XO, UA, and malondialdehyde, which was accompanied by inhibition of ischaemia and I/R-induced reductions in reduced glutathione level, enzymatic antioxidant activities and increase in myeloperoxidase activity and TNF-α and IL-6 levels by atorvastatin treatment. Additionally, atorvastatin blocked ischaemia and I/R-induced increase in VCAM-1 expression, caspase 3 activity, 8-hydroxydeoxyguanosine level and ovarian DNA fragmentation index. Conclusion For the first time, this study revealed that atorvastatin-mediated downregulation of VCAM-1 and XO/UA/caspase 3 signaling averts oxidative injury, inflammation, and apoptosis induced by ovarian ischaemia/reperfusion injury.

Physiological Characterization of the Transporter-Mediated Uptake of the Reversible Male Contraceptive H2-Gamendazole Across the Blood-Testis Barrier. J Pharmacol Exp Ther 2022; 382:299-312. [PMID: 35779861 PMCID: PMC9426764 DOI: 10.1124/jpet.122.001195] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2022] [Accepted: 06/14/2022] [Indexed: 11/22/2022] Open
Abstract
The blood-testis barrier (BTB) is formed by a tight network of Sertoli cells (SCs) to limit the movement of reproductive toxicants from the blood into the male genital tract. Transporters expressed at the basal membranes of SCs also influence the disposition of drugs across the BTB. The reversible, nonhormonal contraceptive, H2-gamendazole (H2-GMZ), is an indazole carboxylic acid analog that accumulates over 10 times more in the testes compared with other organs. However, the mechanism(s) by which H2-GMZ circumvents the BTB are unknown. This study describes the physiologic characteristics of the carrier-mediated process(es) that permit H2-GMZ and other analogs to penetrate SCs. Uptake studies were performed using an immortalized human SC line (hT-SerC) and liquid chromatography-tandem mass spectrometry (LC-MS/MS). Uptake of H2-GMZ and four analogs followed Michaelis-Menten transport kinetics (one analog exhibited poor penetration). H2-GMZ uptake was strongly inhibited by indomethacin, diclofenac, MK-571, and several analogs. Moreover, H2-GMZ uptake was stimulated by an acidic extracellular pH, reduced at basic pHs, and independent of extracellular Na+, K+, or Cl- levels, which are intrinsic characteristics of OATP-mediated transport. Therefore, the characteristics of H2-GMZ transport suggest that one or more OATPs may be involved. However, endogenous transporter expression in wild-type Chinese hamster ovary (CHO), Madin-Darby canine kidney (MDCK), and human embryonic kidney-293 (HEK-293) cells limited the utility of heterologous transporter expression to identify a specific OATP transporter. Altogether, characterization of the transporters involved in the flux of H2-GMZ provides insight into the selectivity of drug disposition across the human BTB to understand and overcome the pharmacokinetic and pharmacodynamic difficulties presented by this barrier. SIGNIFICANCE STATEMENT: Despite major advancements in female contraceptives, male alternatives, including vasectomy, condom usage, and physical withdrawal, are antiquated and the widespread availability of nonhormonal, reversible chemical contraceptives is nonexistent. Indazole carboxylic acid analogs such as H2-GMZ are promising new reversible, antispermatogenic drugs that are highly effective in rodents. This study characterizes the carrier-mediated processes that permit H2-GMZ and other drugs to enter Sertoli cells and the observations made here will guide the development of drugs that effectively circumvent the BTB.

Abstract
Background Testicular torsion is a pathological condition which needs emergency surgical intervention. However, after surgical reperfusion, oxidative stress factors cause to germ cell apoptosis. The study was planned to evaluate the efficacy of simultaneous use of Cyclosporine A (CsA) and Nortriptyline (Nort) to repair testicular damages in an experimental torsion/detorsion (T/D) rat model. Methods Male rats (n = 112) were allocated into 7 groups 16 each in; (Group 1); Control group, (Group 2); T/D group, (Group 3–4); CsA 1 and 5 mg/kg, (Group 5–6); Nort 2 and 10 mg/kg and (Group 7); concurrent group, CsA (1 mg/kg) + Nort (2 mg/kg). Right uni-lateral torsion was inducted by twisting testis 720 degrees in the clockwise direction for 1 h. For short-term and mid-term studies, lipid peroxidation, antioxidant enzyme activities, caspase-3 level, histopathological changes and germ cell apoptosis were evaluated. Moreover, in long-term investigation, semen analysis was performed. Results After T/D induction, testis abnormalities both functional and structural were appeared. Pre- and post-treatment with CsA and Nort, separately, reduced MDA and caspase-3 levels, normalized antioxidant levels, ameliorate tissue injury and improved sperm criteria. Conclusion The antioxidant and anti-apoptotic characteristics of CsA and Nort and their protective effects have been shown in our study. Concurrent administration of CsA and Nort in selected low-dose indicated a significant positive effect as compared to the individual drug interventions on the reversal of T/D induced oxidative stress in short-term, apoptosis, and histologic changes in mid-term, as well as semen criteria in the long-term appraisal.

Abstract
Oxidative stress, caused by extreme accumulation of un-scavenged reactive oxygen species, plays an integral role in the Ischemia-Reperfusion (I/R) injury to the testicles following testicular torsion. The current research aimed to examine the protective effects of crocin as a natural antioxidant on testicular I/R injury in rats. Animals were divided randomly into five groups (seven each): (1) sham group, (2) torsion/detorsion (T/D) group, (3) intact group with 100 mg/kg crocin, (4) and (5) T/D groups followed by treatment with two different doses of crocin (50 and 100 mg/kg (IP)). I/R injury was induced by 720° clockwise torsion of the left testicles for 2 h. After 24 h of reperfusion, blood samples and epididymal sperms were collected to measure biochemical (GPx, SOD, and MDA), hormonal (testosterone), and sperm parameters (total sperm recovery, motility, viability, and morphology). Moreover, affected testicles were subjected to histopathology examination. I/R injury caused a significant reduction in sperm characteristics (except for morphology) (P < 0.05), which could not be significantly improved by crocin administration at either dose (P > 0.05). Johnsen's testicular score, mean seminiferous tubular diameter, and germinal epithelial cell thickness were significantly decreased in the T/D group compared to the intact and sham groups. However, crocin could significantly improve the histopathological parameters in both treatment groups compared to the T/D group (P < 0.05). T/D reduced SOD and GPx activity and testosterone level significantly (except for GPx) compared to the sham group (P < 0.05). However, crocin administration could significantly reverse them. Also, crocin reduced the amount of MDA significantly in the high-dose treatment group in comparison to T/D group (P < 0.05). The results of the current study revealed that crocin could be a promising agent to protect against I/R injury following surgical correction of the testicular torsion.

Abstract
This study was performed to evaluate the effect of liraglutide on experimental testicular ischaemia reperfusion in rats in terms of biochemistry, histopathology and immunohistochemistry. A total of 28 male Wistar-Albino rats were divided randomly into 4 groups: control (7), sham (7), ischaemia-reperfusion (7) and ischaemia-reperfusion + liraglutide (7). Biochemically, Nitric Oxide, Malondialdehyde, Superoxide dismutase, Glutathione peroxidase and Catalase levels were measured in the testis. Apoptosis protease activating factor-1 and inducible nitric oxide synthase activity were evaluated immunohistochemically as well. Statistical analyses were made via the Kruskal-Wallis and Mann-Whitney U tests. In the reperfusion group, CAT and SOD values were increased (p > .05), NO and MDA values were decreased (p < .05) after administration of liraglutide. In addition, GPx values were significantly increased in ischaemia reperfusion + liraglutide administered group compared to reperfusion group (p < .05). Apaf-1 and iNOS activity were significantly decreased with the addition of liraglutide treatment to the ischaemia-reperfusion group (p < .05). First of all, we would like to say that liraglutide treatment is moderately preventive against I/R injury in testicular torsion. The anti-inflammatory, antioxidant and antiapoptotic properties of liraglutide are create a moderately protective effect as we show in this study.

Abstract
Testicular torsion (TT) is a common urologic emergency that can occur at any age. It is most common in newborns and during puberty. Prompt evaluation and management is required to salvage the testis following an episode of torsion. TT brings about damage to testicular tissue and spermatogenesis through various hypothesized mechanisms; however there is a consensus that the effects of ischemia, ischemia-reperfusion injury, and oxidative stress account for the most destructive effects. Numerous studies have examined the effects of various agents and therapies in limiting the effects of TT on the testis.

Abstract
AIMS This study was designed to evaluate the protective and therapeutic efficacy of platelet-rich plasma (PRP) against testicular degeneration and germ cell apoptosis after induced spermatic cord torsion/detorsion (TD) in rats. MATERIALS Forty rats were allocated into 5 groups: 1) control, 2) short torsion/detorsion (STD), 3) long torsion detorsion (LTD), 4) protective (PRP/P) and 5) treatment (PRP/T). Testicular ischemia was induced by twisting the right testis 1080° clockwise for 2.5 h. PRP (10 μl) was injected intra-testicular 5 min before (PRP/P) and 3 h after (PRP/T) detorsion. At the end of the experiment, rats were euthanized at 2, 30, 2, and 30 days for groups 2-5 respectively. Nitric oxide, malondialdehyde, catalase, total antioxidant capacity, reduced glutathione, glutathione-S-transferase, interleukin1 beta, tumor necrosis factor, caspase-3, and B-cell lymphoma 2 expressions were assessed in the testes. Moreover, histological examination was performed. KEY FINDINGS PRP treatment significantly mitigated the torsion-detorsion induced testicular degeneration. Particularly, by improving the state of oxidative stress (NO, P = 0.0001) and antioxidant markers (TAC, GSH, GST, P = 0.0001-0.01) and decreasing the expression of IL-1β, TNF-α and cas 3 and increase the BCL2 fold changes (P = 0.0001). The protective use of PRP is superior to the therapeutic use of PRP in the restoration of the testicular histoarchitecture following TD. SIGNIFICANCE This study illustrates the cyto-protective role of PRP against TD induced testicular cell injury that highlight possible application of PRP as a complementary therapy in different testicular degenerative diseases which might attribute to its ability to ameliorate the oxidative stress and inhibit induced apoptosis.

Abstract
Objective Testicular torsion causes migration of neutrophils to the ischemic region and formation of free oxygen radicals that have a critical effect on ischemic reperfusion (I/R) injury. Udenafil is a selective, strong, and reversible inhibitor of phosphodiesterase type enzyme. In our study, we evaluate the protective effect of udenafil against reperfusion injury due to I/R. Materials and Methods Twenty-one male, adult, Wistar-Albino rats aged 8 months were randomly divided into three groups; sham, I/R, and I/R+udenafil. One hour before the detorsion operation, the sham and I/R groupssaline, and I/R+udenafil groups were administered 2 mg/kg udenafil intraperitoneally. Blood samples were collected to evaluate the inflammatory mediators. Spermatogenic factors were evaluated according to Johnsen criteria. Results Histopathological and molecular parameters from all groups were compared. Mean values of TNF-α and IL-1β in venous blood samples were calculated. We observed that TNF-a values were statistically significantly increased in the I/R group than those in sham groups, and these values were decreased with udenafil treatment Furthermore, the glutathione peroxidase (GPx) level was statistically significantly decreased in the I/R group, and treatment with udenafil prevented this decrease. Evaluation of spermatogenesis using the Johnsen scoring system showed no statistically significant difference in mean scores between the groups. Conclusion We concluded that deterioration of biochemical and histopathological parameters are reversed, and injury due to I/R in testicle tissue may be decreased with udenafil treatment. Results of this experimental study show that efficacy of the udenafil treatment in testis torsion should be investigated.

Abstract
Purpose: To investigate the effect of Picroside II on testicular ischemia and reperfusion (l/R) injury and the underlying mechanism. Methods: Sprague-Dawley rats were randomly divided into 4 groups: sham operated group (Sham), Sham with Picroside II treatment group (Sham+ Pic II), l/R group (l/R) and l/R with Picroside II treatment group (I/R+ Pic II). l/R model was established by rotating the left testis 720° in a clock-wise direction for 4 hours. The histopathologic and spermatogenetic evaluation was performed. The apoptosis changes and the levels of HO-1 (heme oxygenase-1), MPO (myeloperoxidase), NOX (NADPH oxidase), SOD (superoxide dismutase), XO (xanthine oxidase) and NOS (nitric oxide synthase) were measured. Results: The seminiferous tubules were damaged in l/R rats, but Picroside II alleviated the changes induced by l/R. The increased level of apoptosis was decreased by Picroside II (P=0.01, 9.05±0.35 vs. 4.85±0.25). The activities of HO-1, MPO, NOX, XO and MDA content were increased and the SOD activity was decreased in l/R (P<0.05) and could be reversed by Picroside II (P=0.03, 405.5±7.5 vs. 304±17U/mgprot; P=0.02, 0.99±0.05 vs. 0.52±0.04 mgprot; P=0.01, 260+7 vs. 189±2 mgprot; P=0.04, 10.95+0.55 vs. 8.75+0.35 U/mgprot; P=0.045, 6.8+0.7 vs. 3.75+0.35 mgprot; P=0.04, 44.5+3.5 vs. 57.5+3.5 mgprot). Western blot showed that the expression of iNOS, nNOS and eNOS were increased in l/R (P<0.05); however, they were decreased after Picroside II treatment (P<0.05). Conclusion: Picroside II attenuated testicular I/R injury in rats mainly through suppressing apoptosis and oxidative stress through reduction of nitric oxide synthesis.

Abstract
PURPOSE Ovarian ischemia-reperfusion (IR) damage continues to be a serious infertility problem. The oxidative stress plays central role in the development of IR injuries. Activation of antioxidants decreases IR injuries; however, the efficacy of antioxidant agents remains controversial. Unfortunately, there has been no evidence for medicinal use of boric acid (BA) and propolis (Prop) on ovarian IR injury on rats so far. This study will provide to reveal the potential applications of the Prop and BA in ovarian IR therapy. METHODS The Sprague-Dawley rats were randomized into five groups: I-control, II-IR, 3 h of ischemia and 3 h of reperfusion, III and IV-a signal dose of oral BA (7 mg/kg) and Prop (100 mg/kg) alone 1 h before induction of IR, V-Prop and BA together 1 h before induction of IR. SOD (superoxide dismutase), CAT (catalase), GSH (glutathione), MPO (myeloperoxidase), MDA (malondialdehyde), and IL-6 (interleukin-6) levels were quantified by ELISA and the TNF-α (tumor necrosis factor-α), 8-OHdG (8-hydroxylo-2'-deoxyguanosin) and Caspase-3 expressions were performed by immunohistochemical analyses. RESULTS BA and Prop pretreatment significantly reduced MPO, MDA, and IL-6 levels and pathologic score in IR rats, with no effects in control group. These agents used in therapy also decreased TNF-α, 8-OHdG and Caspase-3 protein expressions increased by IR. Furthermore, BA and Prop combination showed significant ameliorative effects on ovary injury caused by IR through acting as an antioxidant, anti-inflammatory and antiapoptotic agent. CONCLUSION BA and Prop alone and especially in combination could be developed as therapeutic agents against ovary IR injury.

Abstract
We investigated whether magnesium sulfate (MgSO4) mitigated pulmonary hypertension progression in rats. Pulmonary hypertension was induced by a single intraperitoneal injection of monocrotaline (60 mg/kg). MgSO4 (100 mg/kg) was intraperitoneally administered daily for 3 weeks, from the seventh day after monocrotaline injection. Adult male rats were randomized into monocrotaline (MCT) or monocrotaline plus MgSO4 (MM) groups (n = 15 per group); control groups were maintained simultaneously. For analysis, surviving rats were euthanized on the 28th day after receiving monocrotaline. The survival rate was higher in the MM group than in the MCT group (100% versus 73.3%, p = 0.043). Levels of pulmonary artery wall thickening, α-smooth muscle actin upregulation, right ventricular systolic pressure increase, and right ventricular hypertrophy were lower in the MM group than in the MCT group (all p < 0.05). Levels of lipid peroxidation, mitochondrial injury, inflammasomes and cytokine upregulation, and apoptosis in the lungs and right ventricle were lower in the MM group than in the MCT group (all p < 0.05). Notably, the mitigation effects of MgSO4 on pulmonary artery wall thickening and right ventricular hypertrophy were counteracted by exogenous calcium chloride. In conclusion, MgSO4 mitigates pulmonary hypertension progression, possibly by antagonizing calcium.

Abstract
Testicular torsion/detorsion (T/D) is an inflammatory problem in men genital system with infertility effects. Cyclosporine A (CsA) as an immunosuppressant medication, exerts anti-inflammatory properties in tissue injuries. We sought to compare the efficacy of 3 doses of CsA on oxidative stress, apoptosis and epididymal sperm quality after ipsilateral testicular T/D. METHODS 96 mature male rats were divided into six groups 16 each in: Control group (Group1), Sham operated (Group2), In rest groups, the right testis was twisted 720° in a clockwise direction for 1 h; T/D + 0.1% dimethylsulfoxide) DMSO((Group3), and in groups 4-6; CsA were administered 1, 5, and 10 mg/kg, intravenously (iv) 30 and 90 min after torsion, respectively. RESULTS Tissue malondialdehyde (MDA) level and caspase-3 activity increased and catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities decreased in compared with control group 4 h after detorsion (p < .001). In six rats of each group 24 h after detorsion, histopathological changes and germ cell apoptosis were significantly deteriorated by determining mean of seminiferous tubules diameters (MSTD) and TUNEL assay. Moreover, 30 days after T/D, sperm concentration and motility were examined in rest of animals. CONCLUSIONS Pre- and post-reperfusion CsA diminished MDA and caspase-3levels and normalized antioxidant enzymes activities. Germ cell apoptosis was significantly reduced, as well as, MSTD and long-term sperm insults were improved. Inhibition of mitochondrial permeability transition pore opening is suggested mechanism for cell protection against testicular T/D insults.

Abstract
Objectives: To evaluate protective effects of darbepoetin and tadalafil against ischemia-reperfusion injury in ipsilateral and contralateral testicle. Materials and Methods: Thirty 3-month-old adult male Wistar-Albino rats were randomly divided into 5 groups (A-E). Sham operation was performed in the first group. In Group B, rats did not received any medication after creating 720 degrees torsion of the left testis. The rats in Group C, D and E received darbepoetin, tadalafil, and darbepoetin/tadalafil combination 30 minutes after creating 720 degrees torsion of the left testis, respectively. The testes of rats in these three groups were detorsioned at 90 minutes after drug administration. Both testes were removed at 30 minutes after detorsion. Results: There were significant differences between the groups in terms of the degree of histopathological damage, Johnsen score, fibrosis score and caspase-3 immunoreactivity in the torsioned testes (p: 0.000). The results for each parameter in the left testes were significantly better in the darbepoetin / tadalafil combination group. Similarly, there were also significant differences in the contralateral testes (p: 0.000). Conclusion: The active substances darbepoetin and tadalafil that were used as a combination had protective effects on both testes and produced out better results in preserving testicular histology. Especially in cases where it is not possible to rescue the torsioned testis, this result was more noticeable in the contralateral testis.

Abstract
Objective: To investigate effects of intraperitoneally administration of α-tocopherol loaded nanoparticles (TNP) on ischemia-reperfusion injury in ovaries. Methods: Thirty-five healthy female Wistar rats ~250g were randomized into seven experimental groups (n = 5): Group SHAM: The rats underwent only laparotomy. Group Ischemia: A 3- hour ischemia only. Group I/R: A 3-hour ischemia and a 3-hour reperfusion. Group I/T: A 3-hour ischemia only and 100 mg/kg intraperitoneal administration (IP) of α-tocopherol 2.5 hours after induction of ischemia. Group I/R/T: A 3-hour ischemia, a 3-hour reperfusion and 100 mg/kg IP of α-tocopherol 2.5 hours after induction of ischemia. Group I/TNP: A 3-hour ischemia only and 1 mg/kg IP of TNP 2.5 hours after induction of ischemia. Group I/R/TNP: A 3-hour ischemia, a 3-hour reperfusion and 1 mg/kg IP of TNP 2.5 hours after induction of ischemia. Results: Animals treated with αTNP showed significantly ameliorated development of ischemia and reperfusion tissue injury compared to those of other groups (p=0.001). The significant higher values of SOD, tGSH, GPO, GSHRd and GST were observed in I/R/NC animals compared to those of other groups (p=0.001). Damage indicators (NOS, MDA, MPO and DNA damage level) were significantly lower in I/R/NC animal compared to those of other groups (p=0.001). Conclusion: Intraperitoneal administration of TNP could be helpful in minimizing ischemia-reperfusion injury in ovarian tissue exposed to ischemia.

Abstract
Introduction The aim of the present study was to survey the protective effect of pretreatment with Persian honey on amelioration of side effects of chemotherapy and ischemia/reperfusion induced testicular injury. Materials and methods Forty adult's male wistar rats were divided into four groups of ischemia-reperfusion (IR), honey + ischemia-reperfusion (HIR), Busulfan (B) and Busulfan intraperitoneally+ honey (BH). The seminiferous tubules were rated for their modified spermatogenesis index (SI) by Johnsons score. Detection of single- and double-stranded DNA breaks at the early stages of apoptosis was performed using the in-situ cell death detection kit. Total serum concentration of Follicle-stimulating hormone (FSH) , Luteinizing hormone (LH) and testosterone was measured using ELISA. All data were expressed as mean ± SD and significance was set at p≤0.05. Results Honey improved SI in the HIR and BH groups and serum levels of FSH and LH in the BH and HIR groups (p<0.001). Also, serum levels of testosterone were significantly higher in BH and HIR groups. But, apoptotic cells in IR and B groups significantly increased (p<0.001), while in HIR and BH groups, the number of apoptotic cells decreased and the positive cells of TUNEL (TdT-mediated dUTP-X nick end labelling) staining were detected in spermatocytes and spermatid. Discussion Pretreatment with honey protect testis against chemotherapy and testicular IR injury, increase FSH and LH and testosterone and decrease the cellular damage and apoptosis. Honey can decrease the side effects of chemotherapy on reproductive system and prevent sterility.

Abstract
Torsion/detorsion (T/D) induces testicular damages in both germinal epithelial and interstitial tissues. Ginkgo biloba extract (GbE) exerts antioxidant and free radical scavenger. We investigated the effect of GbE on testicular tissues, Leydig and sperm cells in rats injured with T/D. Twenty-eight Wistar albino rats were randomly assigned into four groups (Control, GbE, Treatment: T/D+GbE, T/D). T/D performed to the rats in torsion, treatment received GbE (50 mg/kg) 1 hr before T/D, GbE group received only GbE (50 mg/kg) and control was defined as sham group. After T/D, the testes along with epididymis were removed and processed. LH-R expression, apoptosis, sperm morphology and histopathological damage scores were determined for each group. Testicular T/D caused significant increases in apoptosis and sperm morphology anomaly, and a significant decrease in Johnsen's testicular biopsy scores, LH-R expression of Leydig cell and normal sperm cell count. GbE ameliorated testicular histopathology and caused significant increases in LH-R expression, normal sperm cell count in the treated and particularly GbE group. Consequently, GbE may prevent testicular injury and enhance Leydig and sperm cell activity following both T/D and normal situation owing to its antioxidant, anti-apoptotic, free radical scavenger and anti-inflammatory effects.

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
The regenerative potential of stem and progenitor cells from ischemic testes of C57Bl/6 mice was studied in vitro (cell culture) and in vivo (mouse model of busulfan-induced suppression of spermatogenesis). Spermatogonial stem cells with phenotypes CD117-CD90+ and CD51-CD24+CD52+ from ischemic testes demonstrated 33-fold and 7-fold increments of cell mass and generated colonies in vitro. Epithelial (CD45-CD31-Sca-1+CD49f+) and endothelial (CD45-CD31+) precursors exhibited lower self-renewal capacity. On day 30 after injection of stem and progenitor cells from ischemic testes to the rete testis zone of the testes of busulfantreated animals, an increase in the count of CD117-CD90+ spermatogonial stem cells, total count, and mobile sperm count in the testes of recipient mice was observed. In addition, we observed an increase in Sca-1+ cell count, recovery of the spermatogenic epithelium in the seminiferous tubules, and appearance of immature Leydig cells in "busulfan" testes; the level of tissue testosterone and fertility index also increased.

Abstract
INTRODUCTION Nitric oxide (NO) plays an important role in the ischemia and reperfusion process. In this study, we aimed to examine the effect of L-arginine, tadalafil, and their combination for prevention of the ischemia reperfusion injury after testis torsion in rats. METHODS A total of 40 adult, male Sprague-Dawley rats were allocated into five groups. Three hours of left testicular torsion was performed in each group, excluding the control group. While the ischemia reperfusion (I/R) group had no treatment, I/R + Arg group received L-arginine, I/R + Td group received tadalafil and I/R + Arg + Td group received tadalafil and L-arginine 30 minutes before the detorsion. Then the left testis was untwisted for four hours of reperfusion. After bilateral orchiectomy, lipid peroxidation (LPx) and glutathione (GSH) activities were examined in testicular tissue. Spermatogenesis was evaluated with Johnsen's score. RESULTS LPx levels of the I/R group were found to be significantly higher than for groups that received drugs for both testes (p<0.001). GSH levels of the combination group were higher than I/R group in ipsilateral testis (p<0.01) and it was significantly higher than other groups for contralateral testis (p<0.001 for I/R group, p<0.01 for I/R + Arg, p<0.05 for I/R + Td). Mean Johnsen's score of the I/R group was found to be significantly lower than treatment groups in ipsilateral testis (p<0.001 for I/R + Arg + Td group, p<0.01 for other treatment goups) and contralateral testis (p<0.001). The mean Johnsen score of the combination group was significantly higher than that of other treatment groups in ipsilateral testis (p<0.05) and it was significantly higher than in the I/R + Td group in the contralateral testis (p<0.05). CONCLUSIONS L-arginine, tadalafil, and combination of these two molecules showed protective effect against ischemia/reperfusion injury for both testes after unilateral testis torsion.

Abstract
INTRODUCTION In this study, we aimed to determine the protective effects of hesperidin, a citrus flavonoid, in a model of testicular ischemia/reperfusion injury in rats. MATERIAL AND METHODS Forty-two pubertal male Wistar-Albino rats were divided into six groups: group 1 - control; group 2 - 50 mg/kg hesperidin (low dose hesperidin) used without torsion (LH group); group 3 - 100 mg/kg hesperidin without torsion (HH group); group 4 - torsion/detorsion group (T/D); group 5 - T/D + 50 mg/kg hesperidin treatment group (T/D + LH); and group 6 - T/D + 100 mg/kg hesperidin treatment group (T/D + HH). Hesperidin was given to the treatment groups 30 min before detorsion. After the fourth hour of reperfusion, orchiectomy was performed on the rats under anesthesia. The tissue samples were examined histologically and biochemically. RESULTS In the T/D group testicular malondialdehyde (MDA) levels were increased significantly (p < 0.001) whereas superoxide dismutase (SOD), catalase (CAT) and glutathione (GSH) levels were decreased compared to the control and other groups. However, hesperidin caused the effect of T/D to become closer to normal biochemical values. In addition, the histological examinations showed that T/D caused damage in the testis but hesperidin reduced this effect. The effects of hesperidin were found to be dose dependent. Thus, applying high doses would generate greater therapeutic effects. CONCLUSIONS In a rat testicular T/D model we observed biochemical and histological damage due to ischemia. However, high and low dose applications of hesperidin were shown to have protective effects against this damage. Therefore, the aforementioned citrus flavonoid may provide positive results in cases of testicular torsion.

Abstract
Stem and progenitor cells were studied on mouse model of testicular ischemia. Testicular ischemia led to a decrease in free testosterone concentration. Hemodynamic changes, interstitial edema, and destruction of spermatogenic epithelium, Leydig, and Sertoli cells were observed in the testicular tissue. Accumulation of degenerative germ cells was accompanied by reduction in the count of spermatogonial stem cells with immunophenotype CD117(-)CD29(+)CD90(+) and CD117(+)CD29(+)CD90(+). Simultaneously with pathomorphological changes in the testes and suppression of spermatogenesis, ischemia reduced the count of hematopoietic progenitor cells, hematopoietic stem cells with immunophenotype Lin(-)CD117(+)Sca-1(+)c-kit(+)CD34(+) and Lin(-)CD117(+)Sca-1(+)c-kit(+)CD34(-), and multipotent mesenchymal stromal cells (CD45(-)CD31(-) CD90(+)CD106(+)) in the testicular tissue. The population of CD45(-)CD31(+)-endothelial cells in ischemic testicular tissue increased.

Abstract
INTRODUCTION The aim of this experimental study was to investigate the histopathological and biochemical effects of pyrrolidine dithiocarbamate, an antioxidant and inhibitor of NF-kβ, on ischemiareperfusion injury in rats. METHODS A total of 21 male Wistar-Albino rats were randomly distributed into three groups as sham group (Group 1), ischemia-reperfusion (I/R) group (Group 2) and I/R with pyrrolidine dithiocarbamate (PDTC) group (Group 3). Left testicles of rats in Groups 2 and 3 underwent testicular torsion of 720° for four hours and 100 mg/kg of PDTC was administered intraperitoneally prior to detorsion in Group 3. An hour after detorsion process, left orchiectomies were performed and 5 ml of intracardiac blood samples were drawn from rats in all three groups. Histopathological examination of testis tissues performed and measurement of superoxide dismutase (SOD) and malondialdehyde (MDA) levels in blood samples were taken. RESULTS Elevated levels of MDA and decreased SOD activity, together with decreased Johnson tubular biopsy scores consistent with I/R injury were observed in Group 2 (p<0.05). Group 1 and Group 3 were similar in terms of MDA levels, SOD activity, and Johnson scores (p>0.05). CONCLUSIONS Our results indicated that PDTC may have beneficial effects for alleviation of I/R injury in testicular tissue in rats. Understanding the underlying mechanisms and exploration of its diagnostic and therapeutic potential requires further randomized, controlled trials on a larger scale.

Abstract
OBJECTIVE To elucidate the mechanism of a possible protective effect of montelukast against testicular ischemia/reperfusion (I/R) injury. MATERIAL AND METHODS Fifty-one adult male Wistar-Albino rats were randomly assigned into 6 groups; sham + saline (S), sham + montelukast (M), I/R + S, I/R + S 30', I/R + M and I/R + M 30'. Saline or montelukast (10 mg/kg) was intraperitoneally administered 30 minutes prior to (S 30', M 30') and during detorsion (I/R + S, I/R + M) in the I/R groups. The I/R groups underwent 2 hours of ischemia followed by 4 hours (early-term) of reperfusion in unilateral testes. Half of the rats underwent 24 hours (late-term) of reperfusion to investigate long-term effects. Testicular tissue samples were examined for biochemical and histopathological parameters. Germ cell apoptosis was evaluated using apoptosis-activating factor 1 (Apaf-1). Inducible nitric oxide synthase (iNOS) activity was analyzed in late-term reperfusion groups. Spermatogenic functions were assessed for each testis based on the Johnsen criteria. RESULTS Unilateral I/R caused a significant increase in serum TNF-α levels in the early-term group compared to the sham groups. Malondialdehyde levels and myeloperoxidase activity were found to be elevated in the I/R groups and accompanied with a significant decrease in glutathione levels when compared to the sham groups. I/R significantly increased iNOS activity and germ cell apoptosis compared to the sham groups. Montelukast treatment significantly reversed all of these parameters and achieved comparable results with the sham groups. Finally, spermatogenic indices were similar for the bilateral testes between all groups. CONCLUSION Montelukast exerts protective effects against testicular I/R injury by inhibiting neutrophil activity, reversing the oxidative stress markers, decreasing iNOS activity and attenuating apoptosis.

Abstract
The aim of this study was to examine the effects of amlodipine (AML) in rat testicular torsion/detorsion damage. In this study, rats were divided into eight groups: (i) sham; (ii) testicular ischaemia, 2 h of ischaemia; (iii) testicular ischaemia/reperfusion (I/R), 2 h of ischaemia followed by 2 h of reperfusion; (iv) ischaemia + AML (5 mg kg(-1)) administered 30 min before ischaemia; (v) ischaemia + AML (10 mg kg(-1)) administered 30 min before ischaemia; (vi) and (vii) I/R + AML (5 mg kg(-1)) and I/R + AML (10 mg kg(-1)) administered 1.5 h after the induction of ischaemia, respectively, and at the end of a 2-h ischaemia period and a 2-h reperfusion period applied; and (viii) sham + AML (10 mg kg(-1)). Significant decreases in levels of superoxide dismutase and glutathione were observed in ischaemia and reperfusion groups when compared with healthy controls. These antioxidant levels increased in AML groups while malondialdehyde levels significantly decreased. While increases in tumour necrosis factor-alpha and transforming growth factor-beta levels were found in the torsion and detorsion groups, significant decreases in the levels of these inflammatory cytokines were observed in the treatment groups. These results demonstrate that AML significantly produced protective effects on testis tissue damage that occurs in the torsion/detorsion model via biochemical, histopathological and molecular pathways.

Abstract
Testicular torsion is a urological emergency most commonly seen in adolescence, involving a decrease in blood flow in the testis resulting from torsion of the spermatic cord that can result in gonad injury or even loss if not treated in time. Testicular ischaemia-reperfusion injury represents the principle pathophysiology of testicular torsion, with ischaemia caused by twisting of the spermatic cord, and reperfusion on its subsequent release. Many cellular and molecular mechanisms are involved in ischaemia-reperfusion injury following testicular torsion. Studies have investigated the use of pharmacological agents as supportive therapy to surgical repair in order to prevent the adverse effects of testicular torsion. Numerous substances have been proposed as important in the prevention of post-ischaemia-reperfusion testicular injury. A range of chemicals and drugs has been successfully tested in animal models for the purpose of mitigating the dangerous effects of ischaemia-reperfusion in testis torsion.

Abstract
PURPOSE Ischemia-reperfusion injury can cause testicular damage and phosphodiesterase inhibitors are reported to regulate antioxidant activity. We investigated the prevention of ipsilateral and contralateral testicular damage using 2 phosphodiesterase inhibitors after testicular detorsion in rats. MATERIALS AND METHODS A total of 28 adult male rats were randomly divided into 4 groups of 7 each, including group 1-sham operation, group 2-testicular torsion and detorsion, group 3- testicular torsion and detorsion with sildenafil administration before detorsion and group 4- testicular torsion and detorsion with udenafil administration before detorsion. Tissue levels of malondialdehyde, total sulfhydryl and nitrite were evaluated, and histopathological changes in the groups were examined. RESULTS Compared to group 1 significantly increased tissue malondialdehyde (p = 0.001), significantly decreased total sulfhydryl (p = 0.038) and insignificantly increased nitrite were found in group 2. Compared to group 2 malondialdehyde decreased significantly and total sulfhydryl increased significantly in groups 3 and 4. The decrease in nitrite was insignificant in the latter 2 groups. Histopathology revealed increased hemorrhage, congestion and edema in group 2 rats. The testicular injury score was lower in groups 3 and 4. In group 2 grades II to IV injury was detected while most specimens in treated groups showed grade II injury. CONCLUSIONS This study indicates that intraperitoneal administration of sildenafil and udenafil efficiently suppresses radical production while decreasing histological changes after testicular ischemia-reperfusion injury.

Abstract
BACKGROUND/PURPOSE The purpose of the study was to determine the effect of (-)-epigallocatechin gallate (EGCG) on testicular ischemia-reperfusion injury in rats. METHODS Forty male Wistar rats were assigned to 5 groups. A sham operation was performed on the animals in group 1. In group 2, after 4 hours of unilateral testicular ischemia, 4 hours of testicular reperfusion was performed with EGCG administered 1 hour before reperfusion. In group 3, the same surgical procedure as in group 2 was performed, but without EGCG. Serum superoxide dismutase activity, creatine kinase, and lactate dehydrogenase were then measured in blood samples from groups 1 to 3. In group 4, after 4 hours of unilateral testicular ischemia, testicular reperfusion was performed. In group 5, the same procedure as in group 4 was performed, but with EGCG administered 1 hour before reperfusion. For groups 4 and 5, bilateral orchiectomy was performed for histologic examination 4 weeks after reperfusion was started. RESULTS Serum superoxide dismutase activity was significantly higher in group 2 than in group 3. The ratios of bilateral testicular weight, mean seminiferous tubule diameter, and germinal epithelial cell thickness were significantly higher in group 5 than in group 4. CONCLUSIONS Therapy with EGCG before reperfusion might exert protective effects via antioxidant activities in a rat experimental model of testicular ischemia-reperfusion injury.

Abstract
We investigated the effects of quercetin on pathological findings on testicular ischaemia-reperfusion (I/R) injury in rats. Twenty-four male Wistar albino rats were randomly assigned into four groups: Group 1, control (n = 5); Group 2, sham (n = 4); Group 3, I/R (n = 8); and Group 4, I/R + quercetin (n = 7). Bilateral testicular artery and vein were occluded for 1 h, followed by reperfusion in I/R and I/R + quercetin animals. Quercetin (20 mg kg(-1) per day) was administrated once daily by gavage to Group 1 and Group 4, respectively, after reperfusion. At the end of the study, bilateral orchiectomies were performed for histopathologic examination. The tissue damage was evaluated with light microscopy. Normal inter-stitium and seminiferous tubules were observed in control group. In the sham group, rats were seen minimal oedema around the seminiferous tubules and congested vascular structures. In Group 3, oedema, vascular congestion and haemorrhage between seminiferous tubules were observed. In Group 4, histopathologic features were markedly less than Group 3 (P = 0.03). Our study demonstrated that quercetin seems to have a protective effect on testis histopathology in rats with testicular I/R.

Abstract
OBJECTIVE To evaluate the effects of growth hormone (GH) as an antioxidant and tissue-protective agent and analyse the biochemical and histopathological changes in rat ovaries due to experimental ischemia and ischemia/reperfusion injury. STUDY DESIGN Forty-eight adult female rats were randomly divided into eight groups. In Group 1, a period of bilateral ovarian ischemia was applied. In Groups 2 and 3, 1 and 2 mg/kg of GH was administered, and 30 min later, bilateral ovarian ischemia was applied (after a 3-h period of ischemia, both ovaries were surgically removed). Group 4 received a 3-h period of ischemia followed by 3h of reperfusion. Groups 5 and 6 received 1 and 2 mg/kg of GH, respectively, 2.5 h after the induction of ischemia. At the end of a 3-h period of ischemia, bilateral vascular clips were removed, and 3h of reperfusion continued. Group 7 received a sham operation plus 2mg/kg of GH. Group 8 received a sham operation only. After the experiments, superoxide dismutase and myeloperoxidase activity and levels of glutathione and lipid peroxidation were determined, and histopathological changes were examined in all rat ovarian tissue. RESULTS Ischemia and ischemia/reperfusion decreased superoxide dismutase activity and glutathione levels in ovarian tissue, but increased lipid peroxidation levels and myeloperoxidase activity significantly in comparison to the sham group. The 1 and 2 mg/kg doses of GH before ischemia and ischemia/reperfusion decreased lipid peroxidation levels and myeloperoxidase activity in the experimental groups. The administration of GH before ischemia and ischemia/reperfusion treatments also increased superoxide dismutase and glutathione levels. The histopathological findings also suggested a protective role of GH in ischemia/reperfusion injury. That is, ovarian tissues in the ischemia groups showed histopathological changes, such as haemorrhage, cell degeneration, and necrotic and apoptotic cells, but these changes in the GH groups were lesser. Moreover, in the ischemia/reperfusion groups, acute inflammatory processes--such as neutrophil adhesion and migration, apoptotic and degenerative cells, stromal oedema and haemorrhage--were present. However, the ovarian tissues of the IR+GH (1 mg) group had minimal apoptotic cells, and the IR+GH (2 mg) group had no apoptotic cells. In addition, the general ovarian histological structures of these groups were similar to those of the healthy control group. CONCLUSIONS The administration of GH is protective against ischemia and/or ischemia/reperfusion-induced ovarian damage. This protective effect can be attributed to the antioxidant properties of GH.

Abstract
The objective of this study was to investigate the effects of dopamine as vasodilator, vitamin C as an antioxidant and combined administration of them on ischaemia-reperfusion (I-R) injury following testicular torsion (TT). Thirty adult male rats were divided into six groups each containing five rats. Testicular ischaemia was achieved by twisting the left testis for 4 h. Group 1 was for determination of the basal values. Group 2 had 4 h TT. Group 3 had 4 h TT and was then treated with dopamine. Group 4 had 4 h TT and was then treated with vitamin C. Group 5 had 4 h TT and was then treated with dopamine and vitamin C. Group 6 was designed as a sham operated group. Testicular torsion caused a significant decrease in the percentage of spermatogenesis and seminiferous tubules diameters compared with the control and sham groups. Administration of dopamine, vitamin C and their combination increased above mentioned parameters and decreased serum malondialehyde levels significantly. However, vitamin C had better results than the other treatments (P < 0.05). In conclusion, a potent antioxidant like vitamin C was found to be more effective than increasing blood flow by a vasodilator like dopamine on improving I-R injury following TT.

Abstract
OBJECTIVE To reveal the effects of montelukast as an antioxidant and tissue protective agent and study the biochemical and histopathologic changes in experimental ischemia and ischemia-reperfusion (I/R) injury in rat ovaries. DESIGN Experimental study. SETTING Experimental surgery laboratory in a university department. ANIMAL(S) Forty-eight rats with experimentally induced ovarian torsion. INTERVENTION(S) Group 1: sham; Group 2: ovarian ischemia; Group 3: a 30-hour period of ischemia followed by a 3-hour reperfusion. Groups 4 and 5: rats administered 10 and 20 mg/kg doses of montelukast before a half-hour of ischemia, then ovarian ischemia applied; after a 3-hour period of ischemia, the bilateral ovaries removed. Groups 6 and 7: 3-hour period of ovarian ischemia applied, then 2.5 hours after the ischemia induction, rats given montelukast. Group 8: sham operation and 20 mg/kg of montelukast; at the end of a 3-hour period of ischemia, 3-hours of reperfusion continued. MAIN OUTCOME MEASURE(S) Measurement of ovarian tissue concentrations of superoxide dismutase (SOD), glutathione (GSH), lipid peroxidation (LPO) and myeloperoxidase (MPO) activity; and histopathologic examination of all ovarian rat tissue. RESULT(S) Montelukast treatment normalized changes of LPO and MPO and stimulated an overproduction of endogenous SOD and GSH. The results of the histologic parameters showed that treatment with montelukast in the I/R group of rats ameliorated the development of ischemia and reperfusion tissue injury. CONCLUSION(S) Montelukast at different doses attenuates ovarian I/R-induced ovary tissue injury in rats.

Abstract
OBJECTIVES To evaluate the acute effects of increased intra-abdominal pressure (IAP) on testicular germ cell apoptosis and the expressions of endothelial nitric oxide synthase (eNOS), inducible nitric-oxide synthase (iNOS), and Johnson's scores in testicular tissue. MATERIALS AND METHODS Twelve male pigs weighing 52 to 55 kg were divided into 2 groups as group 1 (n = 6; gasless [control]) and group 2 (n = 6; 20 mm Hg IAP with CO(2) pneumoperitoneum for 4 hours). In the second group, left laparoscopic nephrectomy was performed during the CO(2) insufflation period. The right testes of pigs were removed. Testicular germ cell apoptosis, expressions of eNOS and iNOS, and Johnson's scores were evaluated for each group. RESULTS The control group (group 1) exhibited low apoptotic cell level and low iNOS and eNOS level in testes. IAP (group 2) resulted in marked increases in germ cell apoptosis, eNOS, and iNOS compared with the control group (group 1) (P <.05). However, no significant difference was noted in Johnson's scores between the 2 groups (P >.05). Moreover, Leydig cell hyperplasia, congestion, and necrosis, which were not documented in the control group, were seen in the study group. CONCLUSIONS The purpose of the present study was to evaluate whether IAP could affect germ cell apoptosis and NOS concentrations in the testes after laparoscopic procedures in an animal model. In such an animal model simulating laparoscopic procedures, we demonstrated that high-pressure and long-lasting CO(2) insufflation cause testicular changes in the acute period.
