Summary
Yisheng injection protects isolated testes from ischemia/reperfusion injury. This study shows Yisheng injection preserves testicular histologic structure during cold preservation and reduces damage from reperfusion.
Area of Science:
- Reproductive biology and organ preservation.
- Investigating cellular and tissue-level responses to ischemia/reperfusion (I/R).
Context:
- Isolated testes are susceptible to damage during preservation and reperfusion.
- Understanding the mechanisms of I/R injury is crucial for improving organ transplantation and preservation techniques.
Purpose:
- To evaluate the histological and histochemical changes in isolated testes subjected to cold preservation and ischemia/reperfusion (I/R).
- To determine the protective efficacy of Yisheng injection against I/R-induced testicular injury.
Summary:
- Cold preservation of isolated testes at 4°C for 24 hours induced mild endothelial cell (EC) injury, with significant histological alterations observed beyond 24 hours.
- Subsequent 37°C reperfusion exacerbated testicular damage, affecting ECs, seminiferous epithelium, and mesenchyme.
- Yisheng injection demonstrated a protective effect, preserving testicular histologic structure during 24-hour cold preservation and mitigating I/R injury.
Impact:
- Yisheng injection may offer a therapeutic strategy to improve the outcomes of isolated testicular preservation.
- Findings contribute to the understanding of testicular I/R injury and potential interventions.
