Attenuation Effect of Salvianolic Acid B on Testicular Ischemia-Reperfusion Injury in Rats. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022; 2022:7680182. [PMID: 35069978 PMCID: PMC8776430 DOI: 10.1155/2022/7680182] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/11/2021] [Revised: 09/13/2021] [Accepted: 12/24/2021] [Indexed: 11/17/2022]
Abstract
During testicular ischemia-reperfusion, overproduction of reactive oxygen species is associated with testicular injury. We injected hydrogen peroxide (a representative of reactive oxygen species) into normal testis via the testicular artery. The experiment demonstrates that reactive oxygen species can cause spermatogenic injury. Salvianolic acid B, the most abundant bioactive component in Salvia miltiorrhiza Bunge, has been reported to possess a potent antioxidant activity. This study was conducted to evaluate the effect of salvianolic acid B on testicular ischemia-reperfusion injury in a rat testicular torsion-detorsion model. Rats were randomly separated into three groups, including 20 rats in each group: control group with sham operation, testicular ischemia-reperfusion group, and testicular ischemia-reperfusion + salvianolic acid B-treated group. In the testicular ischemia-reperfusion group, left testicular torsion of 720° for 2 hours was induced, and then testicular detorsion was carried out. Rats in the salvianolic acid B-treated group additionally had salvianolic acid B administered intravenously at detorsion. At 4 hours after detorsion, testes of 10 rats from each group were collected to analyze the protein expression of xanthine oxidase which catalyzes generation of reactive oxygen species and malondialdehyde concentration (an indirect indicator of reactive oxygen species). At 3 months after detorsion, testes of the remaining 10 rats from each group were collected to analyze spermatogenesis. Compared with the control group, xanthine oxidase protein expression and malondialdehyde concentration in ipsilateral testes of testicular ischemia-reperfusion group increased significantly, while spermatogenesis decreased significantly. In the salvianolic acid B-treated group, xanthine oxidase protein expression and malondialdehyde concentration in ipsilateral testes decreased significantly, while spermatogenesis increased significantly, compared with the testicular ischemia-reperfusion group. These results suggest that salvianolic acid B can attenuate testicular torsion/detorsion-induced ischemia/reperfusion injury by downregulating the xanthine oxidase protein expression to inhibit reactive oxygen species formation.

Abstract
Objective To investigate the effect of early-life unilateral testicular torsion on adult male fertility. Methods Clinical information was collected for 122 patients who had experienced unilateral testicular torsion at a median age of 15.5 years. The recent pregnancy rate and time to pregnancy experienced by the patients’ female partners were assessed by structured interviews. Data were analyzed by the chi-squared test and Student’s t-test. Results Seventy-two patients with testicular torsion met the criteria for inclusion in our analyses; 49 had undergone orchiectomy, while 23 had undergone surgical repositioning/orchiopexy. The pregnancy rate and median time to pregnancy were 83.67% (41/49) and 1.6 years, respectively, in the orchiectomy group, whereas they were 91.30% (21/23) and 0.75 years, respectively, in the repositioning/orchiopexy group. The recent pregnancy rate was higher in patients with torsion in childhood than in patients with torsion in adolescence; it was lowest in patients with torsion in adulthood. Surgical repositioning/orchiopexy yielded a significantly better recent pregnancy rate among the three groups, based on age at the time of torsion, and a shorter time to pregnancy than orchiectomy in patients with torsion in adolescence. Conclusion Onset of unilateral testicular torsion early in life has a negligible effect on adult male fertility.

A systematic review and meta-analysis. Emerg Radiol 2018; 25:281-292. [PMID: 29335899 DOI: 10.1007/s10140-018-1579-x] [Citation(s) in RCA: 25] [Impact Index Per Article: 4.2] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2017] [Accepted: 01/03/2018] [Indexed: 12/17/2022]
Abstract
PURPOSE A positive whirlpool sign (WS) is defined as the presence of a spiral-like pattern when the spermatic cord is assessed during ultrasonography (US), using standard, high-resolution ultrasonography (HRUS) and/or color Doppler sonography (CDS), in the presence of testicular torsion. The objective of this review was to assess the validity and accuracy of this sign by performing a comprehensive systematic literature review and meta-analysis. METHODS In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, a comprehensive literature search was performed (August, 2017), using the following databases: BMJ Best Practice, Cochrane Library, Embase, PubMed, Scopus, and Web of Science. Selected studies were further assessed for relevance and quality using the Oxford 2010 Critical Appraisal Skills Program (CASP). RESULTS Of the studies assessed, a total of 723 participants were included, with a mean of 72.3 (SD 71.9) participants. Of the participants, 226 (31.3%) were diagnosed with testicular torsion (TT). Meta-analysis of the studies that provided sufficient data resulted in a pooled sensitivity and specificity of the WS of 0.73 (95% CI, 0.65-0.79) and 0.99 (95% CI, 0.92-0.99), respectively. Removal of all neonates increased the pooled sensitivity to 0.92 (95% CI, 0.70-0.98) while the pooled specificity remained almost unchanged at 0.99 (95% CI, 0.95-1.00). The estimated summary effect of all studies with sufficient data was 4.34 (95% CI, 1.01-7.67; n = 394; p = 0.001). A large degree of heterogeneity was suggested by an I2 statistic of 88.27% (95% CI, 68.60-98.68%). Removal of neonatal subjects increased the estimated summary effect to 5.32 (95% CI, 1.59-9.05; n = 375; p = 0.001). CONCLUSION The WS, when correctly diagnosed, may be viewed as a very definitive sign for TT in the pediatric and adult populations. However, its role in neonates is limited.

Abstract
INTRODUCTION Testicular damage caused by ischemia reperfusion injury can be determined by malondialdehyde (MDA) expression and grading of the histopathological damage to seminiferous tubules. The aim of this study was to investigate the effect of Tationil Glutathione administration on testicular damage following experimental torsion and detorsion. METHODS Eighteen Wistar albino rats, 5.5-6 months old and weighing 250-300 g, were divided into three equal groups. In the first group (T), torsion was created by rotating the left testis 720° in a clockwise direction and maintained for 4 h. In the T/D group, after 4 h of torsion, detorsion was performed and maintained for 3 h. In the T/D-GLUT group, we injected 25 mg iv gluthatione before performing detorsion (onset time of agent is ±5 min). RESULTS The lowest malondialdehyde (MDA) expression was observed in the T/D-GLUT rats (P < 0.05). Grading of the histopathological damage to seminiferous tubules showed the damage to be worst in T/D and least in T/D-GLUT rats (P < 0.05). CONCLUSION Tationil Glutathione inhibits formation of reactive oxygen species in testicular tissue during ischemia and reperfusion injury caused by experimental torsion and detorsion in Wistar rats.

Long-term effects of the testicular torsion on the spermatogenesis of the contralateral testis and the preventive value of the twisted testis orchiepididymectomy. Acta Cir Bras 2012; 27:388-95. [DOI: 10.1590/s0102-86502012000600006] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2012] [Accepted: 04/16/2012] [Indexed: 11/21/2022] Open
Abstract
PURPOSE: To determine whether the testicular torsion causes long-term effects on the spermatogenesis of the contralateral testis, and whether the orchiepididymectomy of the twisted testis could prevent them, using specific spermatogenesis parameters to elucidate the conflicting results in the literature. METHODS: Seventy-four pubertal male Wistar rats were randomly selected. The experimental group consisted of 40 rats, divided into four subgroups, submitted to 1.080 degrees counterclockwise left testicular torsion and its scrotal fixation at the beginning of the experiment, and left orchiepididymectomy at one, five, ten and 90 days, respectively. The control group consisted of 24 rats, divided into four sham operation control subgroups. An additional control subgroup consisted of the ten remaining rats, submitted only to the left orchiepididymectomy at the beginning. At 90 days, the contralateral testes of the experimental and control subgroups were collected for the evaluation of their spermatogenesis parameters: testicular weight, seminiferous tubular diameter, Johnsen score and differential counting of the germ cells. RESULTS: No statistically significant differences were observed among the experimental and control subgroups for all of the spermatogenesis parameters of the contralateral testes. CONCLUSIONS: Testicular torsion does not cause long-term effects on the spermatogenesis of the contralateral testis in pubertal rats, and the orchiepididymectomy of the twisted testis is not necessary for preventive purposes for the contralateral spermatogenesis.
