Introduction:
Testicular torsion is a sudden rotation of the testis towards its axis, which causes the twisting of the spermatic cord. Post-detorsion reperfusion will cause inflammation and trigger oxidative stress, which generates reactive oxygen species (ROS). Malondialdehyde (MDA) is an organic compound formed from ROS frequently used as an oxidative stress biomarker during ischemia and ischemia-reperfusion injury. In some organs, stem cell administration on the damaged organ is essential in preventing cellular damage and death. This study aimed to learn about the effect of hADSC administration on an ischemia-reperfusion injury.
Material And Methods:
A total of 22 Wistar rats divided into 5 groups, two groups each consist of 5 male Wistar rats with testicular torsion model without hADSC therapy (group I), while 2 other groups consist of 5 rats with testicular torsion model were given 1.0×106 cells intratesticular hADSC injection 30 minutes after testicular detorsion (group II). Both groups were euthanized at 1 and 4 weeks of observation. The last group consists of 2 rats without any treatment or model (negative control group). Following euthanasia, testicular tissue was harvested for MDA expression measurement using ELISA and histopathological examination. Statistical analysis using an one way ANOVA was done with SPSS version 21.0.
Results:
The result of MDA examination using the ELISA method has shown a concentration difference between group I (control) and group II (hADSC treatment). Testicular MDA concentration in the treatment group was significantly lower on the 1st and 4th week of observation (p2=0.000, p4=0.016). Post hoc analysis showed no statistically different between therapy and healthy group (p=0.972). On histopathological examination, Johnsen score in the treatment group was significantly higher on the 4th week of observation (p=0.044). Post hoc analysis showed no statistically different between therapy and healthy group (p=0.195).
Conclusion:
Intratesticular hADSC administration can inhibit ROS formation due to ischemia-reperfusion injury in testicular tissue after testicular detorsion in Wistar rats.
