Abstract

Objectives: The aim of the study was to investigate the effect of hyperbaric oxygen-preconditioning (HBO-PC) and ozone-preconditioning (O3-PC) on oxidative/nitrosative stress induced by tourniquet ischemia/reperfusion (I/R) in rat skeletal muscle. Methods: Thirty-two Wistar-Albino-type male rats included in the study were divided into four groups of equal number: 1) sham operation, 2) I/R, 3) I/R+HBO-PC, or 4) I/R+O3-PC. One session of 3-4 L/min 100% oxygenation for 60 min at 3 absolute atmosphere (ATA) was defined as one dose of HBO; in total, 7 doses of HBO-PC were administered before ischemia. One dose of O3 comprised 0.7 mg/kg ozone/oxygen mixture, administered intraperitoneally; a total of 4 doses of O3-PC were administered before ischemia. The I/R model was performed in anesthetized rats by clipping right femoral artery to induce 2 h ischemia followed by 22 h of reperfusion. The right gastrocnemius muscle and venous blood samples were harvested. Tissue was assayed for levels of malondialdehyde (MDA), inducible nitric oxide synthase (iNOS), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px). Serum was assayed to measure the level of nitrite-nitrate (NOx). Results: Tissue MDA level, SOD activity, and serum NOx level were increased, whereas GSHPx was decreased in the I/R group. MDA and NOx levels were decreased, whereas GSH-Px activity was increased in both the I/R+HBO-PC and I/R+O3-PC groups. SOD activity was increased in the I/R+O3-PC group, but did not change significantly in the I/R+HBO-PC group. iNOS staining score and intensity were lower in the I/R+HBO-PC and I/R+O3-PC groups than I/R group. Conclusion: Both O3-PC and HBO-PC reduced tissue lipid peroxidation, NOx levels, and iNOS staining scores in the experimental I/R model. Our data suggest that HBO-PC and O3-PC protect against oxidative/nitrosative stress induced by I/R in rat skeletal muscle.

Özet

Amaç: Bu calışmanın amacı hiperbarik oksijen (HBO-PC) ve ozon on-uygulamasının (O3-PC) sıcanların iskelet kasında turnike ile iskemi-reperfuzyon (‹/R) sonucunda oluşan oksidatif/nitrosatif stres uzerine etksini araştırmaktır. Çalışma planı: Otuziki adet Wistar-Albino tipi erkek sıcan calışmaya dahil edildi ve eşit sayıda dort gruba ayrıldı; 1) sham operasyonu, 2) ‹/R, 3) ‹/R+HBO-PC veya 4) ‹/R+O3-PC. ATA altında ve dakikada 3-4 L olmak uzere 60 dakika %100 oksijen uygulaması bir doz HBO olarak tanımlandı ve toplam 7 doz HBO on-uygulaması yapıldı. İntraperitoneal yapılan 0.7 mg/kg ozon/oksijen karışımı bir doz O3 olarak tanımlandı ve toplam 4 doz O3 on-uygulaması yapıldı. ‹skemi-reperfuzyon modeli, anestezi altındaki sıcanların sağ arka bacaktaki femoral arterlerinin okluzyonu ile 2 saatlik iskemi ve takiben 22 saatlik bir reperfuzyon ile oluşturuldu. Sağ gastrokinemius kası ve venoz kan ornekleri alınarak uygun şartlarda saklandı. Doku orneklerinde malondialdehit (MDA) seviyesi ile glutatyon peroksidaz (GSH-Px) ve superoksit dismutaz (SOD) aktiviteleri olculdu ve induklenebilir nitrik oksit sentaz (iNOS) boyaması yapıldı. Serumda nitrit-nitrat (NOx) olculdu. Sonuçlar: I/R grubunda doku MDA seviyesi ile SOD aktivitesi ve serum NOx seviyesi arttı. Bu grupta GSH-Px aktivitesi azaldı. I/R+HBO-PC ve I/R+O3-PC gruplarında MDA and NOx seviyeleri azalırken, GSH-Px aktivitesi arttı. I/R+O3-PC grubunda SOD aktivitesi artarken, I/R+HBOPC grubunda SOD aktivitesi de.işmedi. I/R+HBO-PC ve I/R+O3-PC gruplarındaki iNOS boyama skoru ve yo.unlu.u ‹/R grubundan daha duşuk olarak tespit edildi. Çıkarımlar: HBO ve O3 on-uygulamaları, sıcan iskelet kasında deneysel I/R modelinde lipid peroksidasyonunu, NOx seviyesini ve iNOS boyama skorunu azaltmaktadır. HBO ve O3 on-uygulamaları nın sıcan iskelet kasında I/R ile oluşan oksidatif/nitrosatif strese karşı koruyucu etkisi olabilir.
