Abstract
BACKGROUND Torsion of the spermatic cord is a hazardous and common urologic issue. The current work evaluates the possible protective effect of pregabalin (PGB) and xanthenone (XAN) in testicular ischemia/reperfusion injury induced by testicular torsion/detorsion in rats. MATERIALS AND METHODS Seven groups of adult male Wistar albino rats were allocated randomly into seven groups, namely, sham control, torsion/detorsion (T/D), PGB 50 mg/kg, PGB 100 mg/kg, XAN 1 mg/kg, XAN 2 mg/kg, and PGB 50 mg/kg plus XAN 1 mg/kg groups. Serum cholesterol and testosterone levels were determined. Also, the levels of malondialdehyde (MDA), reduced glutathione (GSH), nitric oxide (NO), superoxide dismutase (SOD), tumor necrosis factor-α (TNF-α), nuclear factor kappa B (NF-қB), angiotensin (Ang) II, Ang-(1-7), and angiotensin-converting enzyme2 (ACE2) were assessed in testicular tissue. Immunohistochemical analysis of heme oxygenase-1 (HO-1) and caspase-3 was performed. Finally, the histopathological examination of the testicular tissues was performed. RESULTS The PGB 50 mg/kg, PGB 100 mg/kg, XAN 1 mg/kg, XAN 2 mg/kg, and PGB 50 mg/kg plus XAN 1 mg/kg groups showed a significant decrease in serum cholesterol, MDA, NO, TNF-α, NF-қB, and Ang-II levels coupled with a significant increase in both testosterone and ACE2 expression. Furthermore, all test groups showed a significant improvement in the histopathological picture with a reduction in caspase-3 and an increase in HO-1 immunoexpression in testicular tissue. CONCLUSION PGB and XAN may have promising effects on preventing testicular T/D injury through antioxidant, anti-inflammatory, and antiapoptotic actions.

Abstract
BACKGROUND Testicular torsion is still an urgent surgical condition and without any treatment it can cause infertility. The main pathophysiology of testicular torsion ischaemic injury however; the main sequalae of detorsion is reperfusion injury. Furthermore; treatments to prevent ischemic reperfusion injury due to decreased blood flow are important to preserve testicular function. AIMS Human chorionic gonadotropin β (β-hCG) is an anabolic hormone that supports steroidogenesis and spermatogenesis. Vitamin C (Vit-C) is one of the water-soluble vitamins and is also a potent antioxidant in ischemic damage. Moreover, it has protective effects by increasing blood and lymph flow in the testicles. The aim of this study is to investigate the effects of β-hCG, Vit-C and their combination on ischemic reperfusion injury occurring after surgical treatment of testicular torsion. STUDY DESIGN Animal research studies. METHODS The study was performed on 25 male Wistar albino rats. The animals were divided equally into 5 groups. In the first group "Control Group," left orchiectomy was performed. In the second group "Sham Group," a 720° clockwise torsion was created and after 4 h of left testicular torsion it was detorsioned for 4 h and then left orchiectomy was performed. In the third group same procedure was applied with 30 mg vitamin C was administered via intraperitoneal route once a week for 3 weeks. In the fourth group after same surgical procedures 75 IU β-hCG was administered via intraperitoneal route once a week for 3 weeks. In the fifth group after 4 h left testicle torsion it was detorsioned for 4 h then, 75 IU β-hCG and vitamin C together were administered via intraperitoneal route once a week for 3 weeks. Left orchiectomy was performed after 3 weeks in the third, fourth and fifth groups. Specimens were evaluated histologically. RESULTS Testicular tissue histopathological evaluations were performed. A high histopathological stage indicates more testicular damage, and a low one was indicated less testicular damage. The average histopathological grade of vitamin C + β-hCG group was significantly higher than the average histopathological grade of the control, the sham group and vitamin C group. The average histopathological grade of the vitamin C group was significantly lower than the average histopathological grade of sham and β-hCG groups. The ratio of the testicular atrophy of the Vitamin C + β-hCG group (100%) was higher than sham (40%) and β-hCG (40%) groups with a significant difference. A significant statistical difference was found among all groups histopathological grades of testicular tissue. CONCLUSION In animals taking vitamin C, an improvement of histopathological findings and a significant decrease in histological stages has been provided. However, it was observed that the histological findings of β-hCG and β-hCG + vitamin C groups worsened. It was found that β-hCG increased oxidative damage in the testicles and this damage can be so severe that exceeding the capacity of potent antioxidants such as Vitamin C. We believe that β-hCG can be harmful to testicles exposed to oxidative damage.

Pentoxifylline improves the survival of spermatogenic cells via oxidative stress suppression and upregulation of PI3K/AKT pathway in mouse model of testicular torsion-detorsion. Heliyon 2021; 7:e06868. [PMID: 33997400 PMCID: PMC8095127 DOI: 10.1016/j.heliyon.2021.e06868] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 08/28/2020] [Accepted: 04/16/2021] [Indexed: 11/20/2022] Open
Abstract
Testicular torsion-detorsion results in enhanced formation of free radicals which contribute to the pathophysiology of testicular tissue damage. Recent reports have identified protective role of pentoxifylline (PTX) against free radicals. Thus, we determined the protective effect of pentoxifylline against testicular damage in mouse model of testicular torsion-detorsion. Twenty (6 weeks old) male mice were divided into 4 groups of 5 animals each namely: Control (sham operated group), T1 (Torsion-detosion + single dose 100 mg/kg PTX, T2 (torsion-detorsion + 20 mg/kg PTX for 2 weeks and T/D (torsion-detorsion only). Animals in T1, T2 and T/D groups underwent 2 h of testicular torsion with the left testes rotated 720° (clockwisely) followed by 30 min of detorsion. After detorsion, drug administration was done intraperitoneally. The left testes of all the animals were excised on the 35th day after torsion-detortion for histopathological and biochemical assay. Histomorphological analysis of the seminiferous tubules showed that there were significant increase (P < 0.01 or 0.05) in the mean seminiferous tubule diameter, Johnson score and germ cells of animals in Control and T1 compared to T2 and T/D with no significant difference (P > 0.05) in testes weight, sertoli, leydig and myoid cells in all groups. IHC results showed significant increase (P < 0.01 or 0.05) in id4 and scp3 protein markers in Control, T1 and T2 compared to T/D. Oxidative stress analysis revealed that Pentoxifylline significantly increased (P < 0.01 or 0.05) the level of SOD, catalase, mRNA expression of akt and pi3k genes but significantly suppress (P < 0.01 or 0.05) MDA and Caspase-3 level in Control, T1 and T2 compared to T/D. Pentoxifylline could be used as an adjunct therapy to surgery in the treatment of torsion-detorsion related testicular injury, However, Further studies are needed to evaluate the effects of pentoxifylline on 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 is an emergency, and unless there is an urgent intervention, irreversible ischaemic damage and gonad loss occur in the testicle. We aimed to investigate myricetin's antioxidant properties as well as its protective effect against ischaemia-reperfusion (I/R) damage in the testicular torsion model. A total of 18 rats were divided into three equal groups. Group 1 was the sham group. Group 2: testicular torsion was performed, and orchiectomy was done 2 hr after detorsion. Group 3: received torsion and 1 mg/kg intraperitoneal myricetin was given 30 min before detorsion, and orchiectomy was applied 2 hr after detorsion. We evaluated tissue malondialdehyde, superoxide dismutase, and catalase levels and Johnsen Testicular Biopsy Score to show its histopathological effect. There was a statistically significant decrease in MDA values in myricetin group compared to Group 2 (p < .017). There was no significant difference in the statistical analysis of SOD and CAT values (p = .337 and p = .025). There was a statistically significant difference in testicular I/R damage in the myricetin group compared to Group 1 and Group 2 (p < .017). Myricetin treatment significantly decreased testicular tissue damage compared to the torsion group but did not reach the values close to the control group.

J Pediatr Urol 2019; 15:43.e1-43.e7. [PMID: 30502312 DOI: 10.1016/j.jpurol.2018.09.012] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2018] [Accepted: 09/14/2018] [Indexed: 12/14/2022]
Abstract
BACKGROUND Testicular torsion is a surgical emergency mainly affecting adolescent boys, with a relatively high rate of missed torsion and testicular loss secondary to delay in prompt diagnosis and surgical intervention. With ischemic reperfusion injury as its underlying culprit, testicular torsion may respond favorably to remote ischemic conditioning (RIC) where a non-privileged site (e.g. limb) is concurrently rendered ischemic to divert the cascade of reperfusion injury from the privileged organ (e.g. testicle), thus offering a protective effect in improving salvage. This mechanism is established for other organs, whereas it has not been evaluated for testis. AIM It was aimed to evaluate RIC in a rat model of testicular torsion as a proof of principle that, similar to what has been demonstrated in other organs, RIC does offer testicular protection. STUDY DESIGN This is an animal experimental study. Thirty Sprague-Dawley male rats were divided into control group (n = 15) and experimental group (n = 15). Non-survival surgeries of right-sided spermatic cord torsion (720° counter-clockwise twist) were performed for both the groups (45 min) followed by detorsion and reperfusion (5 min) and then orchiectomy. For the experiment group, an intervention of tail clamping to create RIC was applied 5 min after torsion, then unclamping 5 min before detorsion, followed by detorsion and reperfusion for 5 min and then orchiectomy. The testicles were histologically and immunologically examined using a hypoxia inducible factor (HIF-1α) ELISA Kit. The histological findings on ischemic changes, vascular congestion, and immunohistochemistry were quantified using previously described, validated grading systems. RESULTS DISCUSSION: This is the first study to demonstrate the concept of RIC in an animal model of testicular torsion. It is limited by the non-availability of similar studies to compare outcomes and by the caution of extrapolating animal studies on humans. It does lay grounds, however, to subsequent studies to further elaborate on this concept and its clinical applicability. CONCLUSION When RIC is applied in the experimental setting of testicular torsion, there is less evidence of hypoxic injury by histology and immunohistochemistry.

Abstract
Recent evidence suggests that apoptosis is involved in germ cell loss following testicular ischemia-reperfusion (IR) injury. Allopurinol (Allo) is as a free radical scavenger which prevents tissue damage caused by reperfusion and oxygenation after ischemia; however, its effect on apoptosis in this type of injury has not been studied. To examine the effect of allopurinol on germ cell apoptosis following testicular IR in a rat. Forty rats were divided randomly into 4 experimental groups of 10 rats each: group A (Sham)-Sham operated animals; group B (Sham-Allo)-Sham operated rats treated with allopurinol given PO (by gavage) at a dose of 200 mg/kg, once daily, immediately before and 24 h following operation; group C (IR)-rats underwent 90 min of unilateral testicular ischemia and 48 h of reperfusion; group D (IR-Allo)-rats underwent IR and were treated with allopurinol similar to group B. The ipsilateral and contralateral testes were harvested 48 h following operation. Johnsen's criteria and the number of germinal cell layers were used to categorize spermatogenesis. TUNEL assay was used to determine germ cell apoptosis. Statistical analysis was performed using one-way ANOVA test, with P < 0.05 considered statistically significant. Testicular ischemia in rats led to histological damage in the ipsilateral testis. In the contralateral testis minimal damage was observed. Treatment with allopurinol increased significantly Johnsen's score in both the ischemic (7.3 +/- 0.5 vs 5.6 +/- 0.5, P < 0.05) and contralateral (8.9 +/- 0.1 vs 8.3 +/- 0.2, P < 0.05) testis, compared to IR-animals. Germ cell apoptosis in both the ischemic and the contralateral testis increased significantly after IR. Treatment with allopurinol resulted in a significant decrease in germ cell apoptosis in the ipsilateral testis, expressed as the number of positive tubules per 100 tubules (AI-1, (apoptotic index) threefold decrease, P < 0.005) and the number of apoptotic cells per 100 tubules (AI-2, fivefold decrease, P < 0.005) as well as a significant decrease in germ cell apoptosis in the contralateral testis (AI-1, 3.5-fold decrease, P < 0.05, AI-2- sixfold decrease, P < 0.005) compared to IR animals. In a rat model of testicular IR, treatment with allopurinol decreases germ cell apoptosis in both ischemic and contralateral testes and improves spermatogenesis.

Abstract
BACKGROUND It has been demonstrated that brief episodes of sublethal ischemia-reperfusion, so-called ischemic preconditioning, provide powerful tissue protection in different tissues such as heart, brain, skeletal muscle, lung, liver, intestine, kidney, retina, and endothelial cells. Although a recent study has claimed that there are no protective effects of ischemic preconditioning in rat testis, the protective effects of ischemic preconditioning on testicular tissue have not been investigated adequately. The present study was thus planned to investigate whether ischemic preconditioning has a protective effect on testicular tissue. METHODS Rats were divided into seven groups that each contained seven rats. In group 1 (control group), only unilateral testicular ischemia was performed by creating a testicular torsion by a 720 degree clockwise rotation for 180 min. In group 2, group 3, group 4, group 5, group 6, and group 7, unilateral testicular ischemia was performed for 180 min following different periods of ischemic preconditioning. The ischemic preconditioning periods were as follows: 10 minutes of ischemia with 10 minutes of reperfusion in group 2; 20 minutes of ischemia with 10 minutes of reperfusion in group 3; 30 minutes of ischemia with 10 minutes of reperfusion in group 4; multiple preconditioning periods were used (3 x 10 min early phase transient ischemia with 10 min reperfusion in all episodes) in group 5; multiple preconditioning periods were used (5, 10, and 15 min early phase transient ischemia with 10 min reperfusion in all episodes) in group 6; and, multiple preconditioning periods were used (10, 20, and 30 min early phase transient ischemia with 10 min reperfusion in all episodes) in group 7. After the ischemic protocols were carried out, animals were sacrificed by cervical dislocation and testicular tissue samples were taken for biochemical measurements (protein, malondialdehyde, nitric oxide) and histological examination. RESULTS Although decreased tissue malondialdehyde levels were detected in the groups of 2, 3, 4, and 5 compared to group 1, significant decreases were observed in only group 2 and group 5 (p < .05). Nitric oxide levels were numerically decreased in all groups compared to the control group but was statistically significant only in group 5 (p < .05). Histopathological examination demonstrated that all groups subjected to ischemic preconditioning had less tissue damage than group 1 (p < .05). CONCLUSION These results suggest that ischemic preconditioning provides tissue protection in testicular tissue.

Abstract
PURPOSE To study the influence of prepubertal unilateral testicular torsion on spermatogenesis postpubertally. METHODS Sixty prepubertal SD male rats were divided into 6 groups. In each group, animal suffered different courses of unilateral testicular torsion including sham operation, 2- and 6-hour-long torsion, and permanent torsion. Salvia miltiorrhiza was injected as a remedy to release the I/R injury in the 2- and 6-hour-long torted groups. Postpubertally, the percentage of DNA content of haploid cells in the testes was determined individually. RESULTS The percentage of haploid cells in the sham operation group was 76.5+/-1.9%. The number decreased in every other group (p<0.01). Comparing with the same course of torsion, Salvia miltiorrhiza injection could improve the percentage of haploid cells (p<0.01). In the permanent unilateral testicular torted group, the percentage was nearly zero (0.4+/-0.2%). CONCLUSIONS Prepubertal unilateral testicular torsion induces decreased spermatogenesis postpubertally. The result takes place in the bilateral testes. Salvia miltiorrhiza, as an antioxidant remedy, could relieve the injury which manifests improved spermatogenesis.
