Abstract
Testicular torsion is a urological emergency that involves the twisting of the spermatic cord along its course. Compelling pieces of evidence have implicated oxidative stress-sensitive signaling in pathogenesis of testicular I/R injury. Although, surgical detorsion is the mainstay management; blockade of the pathways involved in the pathogenesis may improve the surgical outcome. Experimental studies using various testicular I/R models have been reported in a bid to explore the mechanisms associated with testicular I/R and evaluate the benefits of potential therapeutic measures; however, most are limited by their shortcomings. Thus, this review was intended to describe the details of the available testicular I/R models as well as their merits and drawbacks, the pathophysiological basis and consequences of testicular I/R, and the pharmacological agents that have being proposed to confer testicular benefits against testicular I/R. This provides an understanding of the pathophysiological events and available models used in studying testicular I/R. In addition, this research provides evidence-based molecules with therapeutic potentials as well as their mechanisms of action in testicular I/R.

Abstract
BACKGROUND Testicular torsion is a condition in which a testis rotates around its longitudinal axis and twists the spermatic cord. This in turn results in a significant decrease in blood flow and perfusion of testicular tissue. During Testicular torsion, the testicular tissue is affected by ischemia, heat stress, hypoxia, and oxidative and nitrosative stress. The testicular torsion should be considered an emergency condition and surgical intervention (testicular detorsion ) as the sole treatment option in viable cases involves counter-rotation on twisted testes associated, when possible, to orchipexy, in order to avoid recurrence. Possible testicular detorsion side-effects occur due to reperfusion and endothelial cells injury, microcirculation disturbances, and intense germ cells loss. OBJECTIVES To discuss testicular torsion surgery-based methods, different time frames for testicular torsion induction, and the associated pathophysiology by emphasizing cellular and molecular events as well as different therapeutic agent applications for testicular torsion. MATERIALS AND METHODS We reviewed all original research and epidemiological papers related to testicular torsion condition. RESULTS Testicular torsion causes germ cell necrosis, arrested spermatogenesis, and diminished testosterone levels, with consequent infertility. Among different involved pathophysiological impacts, testicular torsion/detorsion-induced ischemia seems to play the key role by leading the tissue toward other series of events in testis. Numerous studies have used adjuvant antioxidants, calcium channel blockers, anti-inflammatory agents, or vasodilating agents in order to decrease these effects. DISCUSSION AND CONCLUSION To the best of our knowledge, no previously conducted study examined therapeutical agents' beneficial effects post clinical I/R condition in humans. Different agents targeting different pathophysiological conditions were used to ameliorate the ischemia/reperfusion-induced condition in animal models, however, none of the administrated agents were tested in human cases. Although considering testicular detorsion surgery is still the golden method to reverse the testicular torsion condition and the surgical approach is undeniable, the evaluated agents with beneficial effects, need to be investigated furthermore in clinical conditions. Thus, furthermore clinical studies and case reports are required to approve the animal models proposed agents' beneficial impacts.

Abstract
This study aimed to investigate the potential benefits Gum Arabic/Acacia Senegal (GA) in mitigating the harmful effects of cisplatin (CP) on spermatogenesis and testicular health in male adult rats. A total of forty albino rats were used in the study and divided into four groups; control, GA, CP, and Co-treated group, which received both CP and GA concurrently. The results revealed that CP caused a significant increase in oxidative stress and a decrease in antioxidant levels (CAT, SOD, and GSH), which disturbed the testicular machinery. This caused significant histological and ultrastructural damage to the testicular structure, including atrophied seminiferous tubules with severely reduced germinal epithelium. Additionally, CP caused a decrease in reproductive hormones (testosterone and LH), a decline in nucleic proliferation PCNA immunoexpression, and an increase in cytoplasmic apoptotic Caspase-3 protein expression in testicular tissue, when compared to the control and GA groups. Moreover, The CP treatment impaired spermatogenesis and decreased sperm number and motility with abnormal morphology. However, co-administration of GA with CP mitigated the dysfunction in spermatogenesis and reversed testicular damage caused by CP through significantly (P < 0.01) reducing oxidative stress (MDA) and increasing the activities of CAT, SOD, and GSH. Additionally, co-administration of GA elevated the levels of testosterone and luteinizing hormone in blood sera, significantly (P < 0.01) improved the histometric measurements of seminiferous tubules diameter, their epithelial height, Johnsen's score of spermatogenesis, 4-level histological grading scale Cosentino's score, immunohistochemical expression of nucleic PCNA, and cytoplasmic Caspase-3 proteins. Furthermore, TEM examination confirmed the synergistic effect of GA in restoring the germinal epithelial cells ultrastructure, the elongated and transverse sections of spermatozoa in the lumen, and the interstitial tissue. All of these effects resulted in a significant improvement in sperm quality in the Co-treated animals compared with the CP group, as well as, a significant decline in the morphological abnormalities of sperm in Co-treated rats compared to those in the CP group. GA is a valuable agent for ameliorating chemotherapy-related infertility.

Abstract
Chronic asymptomatic orchitis (CAO) is a common cause of acquired non-obstructive azoospermia in dogs. To understand the impact and mode of action of apoptosis, we investigated TUNEL, Bax, Bcl-2, Fas/Fas ligand, and caspase 3/8/9 in testicular biopsies of CAO-affected dogs and compared the results to undisturbed spermatogenesis in healthy males (CG). TUNEL+ cells were significantly increased in CAO, correlating with the disturbance of spermatogenesis. Bcl-2, Bax (p < 0.01 each), caspase 9 (p < 0.05), Fas, caspase 8 (p < 0.01 each), and caspase 3 (p < 0.05) were significantly increased at the mRNA level, whereas FasL expression was downregulated. Cleaved caspase 3 staining was sporadic in CAO but not in CG. Sertoli cells, some peritubular (CAO/CG) and interstitial immune cells (CAO) stained Bcl-2+, with significantly more immunopositive cells in both compartments in CAO compared to CG. Bcl-2 and CD20 co-expressing B lymphocytes were encountered interstitially and in CAO occasionally also found intratubally, underlining their contribution to the maintenance of CAO. Our results support the crucial role of the intrinsic and extrinsic apoptotic pathways in the pathophysiology of canine CAO. Autoprotective Bcl-2 expression in Sertoli cells and B lymphocytes seems to be functional, however, thereby also maintaining and promoting the disease by immune cell activation.

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
OBJECTIVE The aim of this study was to investigate the function of the contralateral testis after unilateral testicular torsion (UTT) and its possible mechanism. METHODS 56 rats were randomly divided into four groups: Group A: Sham operation, Group B: Testicular torsion (TT)+normal saline (NS), Group C: Testicular torsion (TT)+cyclosporine, Group D: Testicular torsion (TT)+NG-Monomethyl-L-arginine (L-NMMA). The right testes were removed 1 week and 8 weeks after surgery, respectively. Biochemistry and histopathologic evaluations were used to evaluate the germ cell damage. RESULTS Compared with Group A, the levels of malondialchehyche (MDA) and nitric oxide (NO)/nitricoxide synthase (NOS) were increased remarkably in Group B. Significant differences were shown between histopathological damages and density and motility of sperm in two groups. Compared with Group B, the levels of MDA and NO/NOS in Group D decreased significantly while mean seminiferous tubule diameter (MSTD) and mean testicular biopsy scoring (MTBS) maintained in a better condition. The levels of major histocompatibility complex (MHC) peptide-tetramer complex in Group C and Group D decreased significantly than Group B, while sperm density and motility were significantly higher than Group B. It was also known that the histopathological damages in Group C and Group D were less than those in Group B in the 8 weeks after operation. CONCLUSION UTT can cause impairment of contralateral testicular function and decrease of spermatogenic function. The mechanism may be related to ischemia-reperfusion (IR) in early stage and autoimmune response in late stage.

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
CONTEXT Acetaminophen overdose is regarded to a common cause of acute liver failure. The hepatotoxicity leads to mitochondrial oxidative stress and subsequent necrotic hepatocellular death. OBJECTIVE This study examines the protective effect of metformin on acetaminophen-induced oxidative stress, inflammation and subsequent hepatotoxicity in mice. MATERIALS AND METHODS Male BALB/c mice were orally administered to acetaminophen (250 mg/kg/d) for a 7-day period. The mice received metformin (100 and 200 mg/kg/d, p.o.) for 21 days. To evaluate acetaminophen-induced oxidative stress, liver tissue level of malodialdehyde (MDA), end product of membrane lipid peroxidation, and activities of superoxide dismutase (SOD) and glutathione (GSH) were measured. Histological analysis and measurement of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were performed. Moreover, tissue concentrations of proinflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), along with, C-reactive protein (CRP) were assessed. RESULTS Acetaminophen caused focal hepatocyte necrosis, inflammation and fatty degeneration, as well as increased tissue levels of AST, ALT, ALP and MDA, and also decreased GSH and SOD activities. Moreover, IL-6, TNF-α and CRP levels were increased following acetaminophen hepatotoxicity. Metformin (200 mg/kg/d) significantly normalized MDA, SOD and GSH levels (p < 0.001), and exerted a hepatoprotective effect by significant decreasing ALT, AST and ALP concentrations (p < 0.001). The tissue levels of IL-6, TNF-α and CRP were markedly decreased by 21-day treatment with metformin (200 mg/kg/d) (p < 0.001). DISCUSSION The results suggest metformin protects hepatocytes against acute acetaminophen toxicity. Metformin is indicated to diminish oxidative stress, proinflammatory cytokines, and hepatocyte necrosis.
