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
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.

Arbutin abrogates testicular ischemia/reperfusion injury in rats through repression of inflammation and ER stress. Tissue Cell 2023; 82:102056. [PMID: 36921493 DOI: 10.1016/j.tice.2023.102056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2022] [Revised: 12/30/2022] [Accepted: 03/06/2023] [Indexed: 03/09/2023]
Abstract
The aim of this study was to investigate the effects of arbutin (ARB) administration on oxidative stress, inflammation, endoplasmic reticulum (ER) stress and apoptosis in an experimental testicular torsion/detorsion (T/D)-induced testicular injury model for the first time. A total of 24 male Sprague-Dawley rats were divided into four groups with six rats in each group: sham control, T/D, T/D+ARB (50 mg/kg) and T/D+ARB (100 mg/kg). Torsion and detorsion times were applied as 4 h and 2 h, respectively. The levels of lipid peroxidation [malondialdehyde (MDA)] and oxidative stress [total oxidant status (TOS) and total antioxidant status (TAS)] in testicular tissues were determined using colorimetric methods. The levels of DNA damage [8-hydroxy-2'-deoxyguanosine (8-OHdG)], antioxidant system [superoxide dismutase (SOD) and catalase (CAT)], pro-inflammatory cytokines [high mobility group box 1 (HMGB1), nuclear factor kappa B protein 65 (NF-κB p65), tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and myeloperoxidase (MPO)], ER stress [78-kDa glucose-regulated protein (GRP78), activating transcription factor 6 (ATF6) and CCAAT-enhancer-binding protein homologous protein (CHOP)] and apoptosis (caspase-3) markers in testicular tissues were determined using commercial enzyme-linked immunosorbent assay (ELISA) kits. Johnsen's testicle scoring system was used for histological evaluation. In the T/D group, it was determined that statistically significant increasing in the levels of oxidative stress, inflammation, ER stress and apoptosis compared with sham control group (p < 0.05). ARB administrations statistically significantly restored testicular I/R damage in a dose dependent manner (p < 0.05). In addition, it was determined that the data of histological examinations supported the biochemical results. Our findings support the hypothesis that ARB may be used as a protective agent against T/D-induced testicular damage.

Abstract
PURPOSE To investigate the protective effects against ischemia reperfusion injury of dipyridamole in a model of induced priapism in rats. MATERIALS AND METHODS Twenty-four male Sprague-Dawley rats were divided into four groups, control, P/R, P/R+DMSO and P/R+D. 3ml blood specimens were collected from vena cava inferior in order to determine serum MDA, IMA, TAS, TOS and OSI values, and penile tissue was taken for histopathological examination in control group. Priapism was induced in P/R group. After 1h, priapism was concluded and 30 min reperfusion was performed. In P/R+DMSO group 1ml/kg DMSO was administered intraperitoneally 30 min before reperfusion, while in P/R+D group 10mg/kg dipyridamole was administered intraperitoneally 30 min before reperfusion. Blood and penis specimens were collected after the end of 30 min reperfusion period. Sinusoidal area (μm2), tears in tunica albuginea and injury parameters in sinusoidal endothelium of penis were investigated. RESULTS Histopathological examination revealed no significant changes in term of sinusoidal area. A decrease in tears was observed in P/R+D group compared to P/R group (p<0.05). Endothelial injury decreased in P/R+D group compared to P/R group (p>0.05). There were no significant differences in MDA and IMA values between groups. A significant increase in TOS and OSI values was observed in P/R+D group compared to P/R group. A significant decrease in TAS levels was observed in P/R+D group compared to the P/R group. CONCLUSIONS The administration of dipyridamole before reperfusion in ischemic priapism model has a potential protective effect against histopathological injury of the penis.

J Obstet Gynaecol Res 2017; 43:895-901. [PMID: 28190281 DOI: 10.1111/jog.13281] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2016] [Revised: 10/28/2016] [Accepted: 12/03/2016] [Indexed: 12/01/2022]
Abstract
OBJECTIVE Our aim was to examine the potential roles of ischemia modified albumin(IMA) and D-dimer as reliable early diagnostic markers of ovarian torsion. MATERIALS AND METHODS 24 Wistar albino rats were included and randomized into three groups. Control (sham) rats underwent laparotomy then bilateral ovaries removed for histopathological examination and concomitant blood sampling for IMA and D-dimer assays after 4 h. In the remaining groups, ovarian ischemia was achieved by rotating bilateral ovaries 1080° clockwise then blood samples were obtained and ovaries were removed after 4 h and 24 h. IMA and D-dimer levels as well as the histopathological injury scores were assessed in all groups. RESULTS A statistically higher significant difference in D-dimer levels in the 4-h torsion group (Group 2) than the other groups (P = 0.001, P < 0.01). Despite absence of statistical significance, the difference in IMA levels between the groups was close to statistical significance (P = 0.064; P > 0.05); accordingly IMA levels were higher in the 24-h torsion group (Group 3), than in 4-h torsion (Group 2) or sham (Group 1) group. CONCLUSION Our results suggest that D-dimer may represent a valuable acute marker of ovarian torsion. The cut-off value for D-dimer was 402 ng/ml. Although rats in Group3 had higher IMA than in other groups, the difference was only close to statistical significance. Also, increasing duration of torsion was associated with reduced D-dimer levels, while IMA levels exhibited an increase during the 24 h period. In contrast with previous studies, IMA appeared to be a potential marker in the long term rather than the short term.

Abstract
OBJECTIVE To investigate the potential diagnostic value of plasma signal peptide, CUB (complement proteins C1r/C1s, Uegf, Bmp1) domain, epidermal growth factor (EGF)-like 1 (SCUBE1) protein in experimentally induced testicular torsion (TT). MATERIALS AND METHODS In this randomized, controlled, experimental study, 24 mature male Wistar rats were divided into four groups: 2- and 4-hour control (groups I and III, respectively), and 2- and 4-hour torsion (groups II and IV, respectively) groups. Torsion was performed by rotating the left testis 720° clockwise and maintained by fixing the testis. Plasma SCUBE1 levels and histopathological damage scores were compared. RESULTS There was significantly greater histopathological damage in the 4-hour torsion group compared with the other groups. SCUBE1 levels in this group were also higher than those in the other groups, and the difference was significant. There were significant correlations between histopathological scores and SCUBE1 levels. CONCLUSION SCUBE1, a novel marker of platelet activation, is elevated in TT. According to our results, platelet activation may play an important pathological role in tissue injury associated with testicular ischemia. Plasma SCUBE1 measurement may have diagnostic, therapeutic, or prognostic value in TT.

Abstract
BACKGROUND Oxidative stress inhibits albumin's ability to complex with cobalt. Feline serum-cobalt binding has not been described. OBJECTIVES The objective was to develop a cobalt binding test for use with feline serum, and correlate the results with other biochemical and cellular constituents in blood, and with clinical diseases of cats. METHODS A colorimetric test of cobalt binding, based on the oxidation-reduction reaction of Co(+2) and dithiothreitol, was developed using feline serum. The test was used to measure cobalt binding in stored serum from 176 cats presented to the University of Illinois Veterinary Teaching Hospital for a variety of disease conditions. Time-matched hematology and biochemical data, and clinical information, were obtained from the medical record of each cat and correlated with the serum-cobalt binding results. RESULTS Serial dilution of feline serum with phosphate-buffered saline resulted in a highly linear decrease in serum-cobalt binding (r(2) = .9984). Serum-cobalt binding of the clinical samples also correlated with albumin concentrations in a stepwise linear regression model (r(2) = .425), and both cobalt binding and albumin were significantly decreased in cases of inflammation. Albumin and cobalt binding also shared significant correlations with several erythron variables, and serum concentration of total calcium and bilirubin. CONCLUSIONS The correlation of cobalt binding measured by a colorimetric test with albumin concentration in the clinical samples and with serum dilution is consistent with feline albumin-cobalt complex formation. Hypoalbuminemia is the likely cause of reduced serum-cobalt binding in inflammation and the correlations observed between cobalt binding and other variables.

Abstract
PURPOSE The purpose of this study was to identify changes taking place in the rat testis at the 24th hour of reperfusion following testicular torsion and to evaluate the effects of resveratrol (RSV), a powerful antioxidant, in preventing these changes using novel biochemical parameters and histopathology. METHODS Eighteen adult male rats were divided into three groups: Sham-operated (S), torsion/detorsion (T/D), and T/D+RSV groups. In the T/D group, testicular ischemia was achieved by rotating the left testis 720° clockwise for 4h. In the T/D+RSV group, 20mg/kg RSV was administered intraperitoneally 30 min before detorsion. All rats were sacrificed 24h after detorsion. Serum and tissue malondialdehyde (MDA) concentrations, ischemia modified albumin (IMA), total oxidative status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), and histopathological damage score were analyzed. RESULTS Serum MDA, IMA, TOS, and OSI levels rose significantly in the T/D group. Serum MDA and IMA values were lower in the T/D+RES groups, but not significantly. OSI and TOS values were lower in the T/D+RES group, and the difference was significant. TAS values decreased significantly in the T/D group and rose in the T/D+RSV group, but not significantly. Ipsilateral tissue MDA values were significantly elevated in the T/D group and decreased in the T/D+RSV group, but not significantly. Apoptosis and histopathological damage increased significantly in the T/D group and decreased significantly in the T/D+RSV group. In the contralateral testis, apoptosis increased significantly in the T/D group. It decreased significantly in the T/D+RSV group. CONCLUSIONS Our findings show that RSV had a protective effect against oxidative damage induced with a testicular T/D model, especially at the antiapoptotic and histopathological level. OSI may be a good guide to the clinical status of testicular T/D.

Abstract
OBJECTIVE To compare the effects of N-acetylcysteine (NAC) and ethyl pyruvate (EP) on experimental testicular ischemia-reperfusion (I/R) injury. DESIGN Randomized, controlled, experimental study. SETTING University hospital. ANIMAL(S) Twenty-four mature male Wistar rats. INTERVENTION(S) Rats were divided into four groups: control group, torsion-detorsion (T/D) group, EP group, and NAC group. In the pretreatment of the NAC and EP groups, 20 mg/kg NAC and 50 mg/kg EP were given intraperitoneally (IP) 30 minutes before detorsion. MAIN OUTCOME MEASURE(S) Serum ischemia-modified albumin (IMA), tissue and serum malondialdehyde, and myeloperoxidase activity levels and histopathological damage scores were then compared. RESULT(S) Ethyl pyruvate and N-acetylcysteine exhibited a protective effect against I/R injury. Of the biochemical parameters evaluated as a result of testicular I/R, only IMA levels were significantly elevated. There was a strong and significant correlation between serum IMA levels and histopathological injury scores, and the increase in serum IMA level exhibited a strong parallel with the increase in histopathological injury. In the EP group, although the histopathological injury score was similar to that of the control group, serum IMA levels were significantly elevated. CONCLUSION(S) Both NAC and EP, the effects of which on I/R injury are evaluated in the present study, reduce such injury in testicular torsion-detorsion. Comparing their effects on IMA levels, NAC may be regarded as a relatively more effective treatment than EP.
