Abstract

PURPOSE: It has been postulated that postischemic reperfusion injury is a phenomenon in testis as the other organs. Caffeic acid phenethyl ester (CAPE) which is an active component of propolis exhibits potential antioxidant properties. We planned an experimental study to determine whether CAPE prevents reperfusion injuiy after testicular detorsion. METHODS: Forty adult male Wistar-Albino rats were divided into four groups each containing 10 rats; sham, torsion, saline-detorsion and CAPE-detorsion. The rats were sacrificed after two hours of720o clockwise torsion. In saline-detorsion group, the rats were given 1 ml of normal saline solution 30 minutes before detorsion, and sacrificed after 4 hours of detorswn following torsion. In CAPE-detorsion group, CAPE (10 /umol/kg) was applied 30 minutes before detorsion. Both testes of sacrificed rats were removed to determine malondialdehyde (MDA) levels and xanthine oxidase (XO) activities. RESULTS: In ipsilateral testis, mean MDA level and XO activity in torsion group were increased when compared to sham group (P<0.001 and P<0.01). While saline-detorsion group mean MDA level and XO activity were increased when compared to torsion group (P<0.01 and P<0.05), they did not differ in CAPE-detorsion group. In contralateral testis, there was no difference in MDA levels and XO activities between groups. CONCLUSION: We conclude that CAPE applied before testicular detorsion may prevent lipid peroxidation and reperfusion injury by scavenging reactive oxygen species which are hazardous for cell membrane.

Özet

AMAÇ: İskemi sonrası reperfüzyon hasarı birçok organda olduğu gibi testiste de kabul edilen bir fenomendir. Spesifik bir propolis bileşeni olan Caffeic acid phenethyl ester (CAPE) antioksidan özellikleri olan kimyasal bir bileşimdir. CAPE'in testiste detorsiyon sonrası reperfüzyon hasarını önleyici etkisinin olup olmadığını araştırmak için bir deneysel çalışma planladık. YÖNTEM: Kırk adet erkek erişkin Wistar Albino rat sham, torsiyon, serum fizyolojik-detorsiyon ve CAPE-detorsiyon olmak üzere her biri 10 rattan oluşan dört gruba ayırıldı. Torsiyon grubunda ratlar sol testise saat yönünde 720o torsiyon uygulandıktan iki saat sonra sakrifıye edildi. Serum fizyolojik-detorsiyon grubunda ratlara detorsiyondan 30 dakika önce 1 mi serum fizyolojik verildi ve detorsiyon uygulandıktan 4 saat sonra sakrifiye edildiler. CAPE-detorsiyon grubunda ise serum fizyolojik yerine yine detorsiyondan 30 dakika önce CAPE (10 pmol/kg) uygulandı. Sakrifiye edilen hayvanların her iki teslisleri malondialdehid (MDA) seviyesi ve ksantin oksidaz (XO) aktivitesinin belirlenmesi için alındı. BULGULAR: İpsilateral testiste torsiyon grubu ortalama MDA seviyesi ve XO aktivitesi sham grubuna göre anlamlı şekilde yükselmişti (P<0.001 ve P<0.01). Serum fizyolojik-detorsiyon grubu ortalama MDA seviyesi ve XO aktivitesi torsiyon grubuna göre anlamlı şekilde yüksek bulunurken (P<0.01 ve P<0.05), CAPE-detorsiyon grubunda ise anlamlı değişiklik gözlenmedi. Kontrlateral testiste bu iki parametre açısından gruplar arasında anlamlı fark yoktu. SONUÇ: Detorsiyon öncesi uygulanan CAPE'nin reperfüzyon sonrası ortaya çıkan ve hücre zarında lipid peroksidasvonu yaparak hücresel hasara sebep olan reaktif oksijen türlerini yok ederek reperfüzyon hasarına engel olmaktadır.
