To compare the effects of NAC and EP on experimental testicular ischemia reperfusion (I/R) injury.
Randomized, controlled, experimental study
Twenty-four mature male Wistar rats
Rats were divided into four groups; control, torsion-detorsion (T/D) group, ethyl pyruvate (EP) group and N-acetylcysteine (NAC) group. In the pretreatment of the NAC and EP groups, 20 mg/kg NAC and 50 mg/kg EP were given intraperitoneally 30 min before detorsion.
Main Outcome Measure(s):
Serum ischemia modified albumin (IMA), tissue and serum malondialdehyde (MDA) and myeloperoxidase (MPO) activity levels and histopathological damage scores were then compared.
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 rise in histopathological injury. In the EP group, although histopathological injury score was similar to that of the control group, serum IMA levels were significantly elevated.
Both NAC and EP, the effects of which on I/R injury are evaluated here, reduce such injury in testicular T/D. Comparing their effects on IMA levels, NAC may be regarded as a relatively more effective treatment than EP.
