Various agents have been tested as preventive treatments for ischemia/reperfusion (IR) damage. In this study, we have investigated for the first time in the literature the efficacy of injection of amniomax (AMX) into testicular parenchyma, which is a commercial medium of rat amniotic fluid, in preventing testicular IR damage related to testicular torsion.
This study aims to evaluate whether or not amniomax has an effect on experimental IR damage in rat testes using biochemical and histopathological methods based on data in the literature. Even if testicular torsion is repaired surgically in early term injury because of de IR damage still occurs. Is it possible to reduce the ischemia reperfusion injury with amniotic fluid and increase the success of treatment?
40 male Wistar albino rats were included. Four groups were formed with 10 rats in each group: Sham, Ischemia/Reperfusion (IR), injection 1 min before detorsion (AMX-BD), injection 1 min after detorsion (AMX-AD). Total Oxidant Status (TOS) and Oxidative Stress Index (OSI) were computed for oxidative stress, and Total Antioxidant Status (TAS) levels were computed for the antioxidant system, for both serum and tissue. Necrosis and microcalcification levels were assessed in the evaluation of testicular histology. P < 0.05 was considered statistically significant.
AMX-AD group has low necrosis degree than IR, Mean serum and tissue levels of TAS, TOS, and OSI parameters were respectively determined as; for TAS: 0.64 ± 0.11 and 0.96 ± 0.25 mmol Trolox Equivalent/L; for TOS: 6.71 ± 0.87 and 9.40 ± 1.03 μmol HO equivalent/L; for OSI: 11.94 ± 3.74 and 10.70 ± 4.23 arbitrary unit.
Our study has investigated for the first time in the literature the efficacy of amniotic fluid in preventing testicular IR damage, and used amniomax (AMX) for this purpose. The limitation of our study may be the small number of rat in the groups.
We think an injection after detorsion is more favorable considering that the AMX-AD group demonstrated significantly lower levels of TOS in serum and tissue and OSI in serum, and significantly higher serum levels of TAS compared to the AMX-BD group, as well as the fact that the morphological protection effect was only observed for injections performed immediately after detorsion.
已经对多种药物进行了测试,作为缺血/再灌注(IR)损伤的预防性治疗方法。在本研究中,我们首次在文献中研究了将羊膜液的商业介质羊膜素(AMX)注射到睾丸实质中,对预防与睾丸扭转相关的睾丸IR损伤的疗效。
本研究旨在根据文献数据,使用生化和组织病理学方法评估羊膜素对大鼠睾丸实验性IR损伤是否有影响。即使在早期损伤中通过手术修复了睾丸扭转,由于IR损伤仍然会发生。羊水是否有可能减少缺血再灌注损伤并提高治疗成功率?
纳入40只雄性Wistar白化大鼠。将其分为四组,每组10只大鼠:假手术组、缺血/再灌注(IR)组、扭转前1分钟注射(AMX-BD)组、扭转后1分钟注射(AMX-AD)组。计算血清和组织的总氧化剂状态(TOS)和氧化应激指数(OSI)以评估氧化应激,计算总抗氧化剂状态(TAS)水平以评估抗氧化系统。在评估睾丸组织学时评估坏死和微钙化水平。P < 0.05被认为具有统计学意义。
AMX-AD组的坏死程度低于IR组,TAS、TOS和OSI参数的平均血清和组织水平分别确定为;对于TAS:0.64±0.11和0.96±0.25 mmol Trolox当量/L;对于TOS:6.71±0.87和9.40±1.03 μmol HO当量/L;对于OSI:11.94±3.74和10.70±4.23任意单位。
我们的研究首次在文献中研究了羊水对预防睾丸IR损伤的疗效,并为此使用了羊膜素(AMX)。我们研究的局限性可能是每组大鼠数量较少。
我们认为考虑到AMX-AD组血清和组织中的TOS水平以及血清中的OSI水平明显低于AMX-BD组,血清TAS水平明显高于AMX-BD组,以及仅在扭转后立即注射才观察到形态学保护作用,扭转后注射更有利。
