Abstract

Background: This study aims to determine the relationshipbetween serum prolidase activity and ischemia duration indifferent ischemia types.Methods: Forty male Sprague Dawley rats were dividedinto five equal groups. The rats were sacrificed and bloodsamples were obtained to determine the basal serumprolidase levels in group 1 (control group) without anyintervention. In groups 2 and 3, the superior mesentericarteries were clamped with simple laparotomy to inducemesenteric ischemia. In groups 4 and 5, the right commonfemoral artery was clamped to induce peripheral ischemiaand blood samples were taken at 120 and at 360 minutes,respectively. The serum prolidase levels were measuredusing the samples obtained from each group.Results: The basal prolidase level in rats was foundto be 266.8±20.5 U/L. The serum prolidase levelsincreased after two-hours of peripheral (404.0±105.6 U/L) and mesenteric ischemia (317.1±121.4 U/L). However, the serum prolidase levels decreased after six-hours of peripheral (346.1±104.9 U/L) and mesenteric ischemia(233.4±36.6 U/L). Although the serum prolidase levelswere elevated in the second hour of mesenteric ischemia,they were lower than the enzyme levels obtained after two-hours of peripheral ischemia (p= 0.006).Conclusion: The serum prolidase level may be animportant predictive biomarker for identifying the durationof ischemia.

Özet

Amaç: Bu çalışmada farklı iskemi tiplerinde serum prolidaz aktivitesi ve iskemi süresi arasındaki ilişkinin belirlenmesi amaçlandı. Ça­lış­ma pla­nı: Kırk erkek Sprague-Dawley cinsi sıçan beş eşit gruba bölündü. Grup 1’deki sıçanlar (kontrolgrubu) bazal serum prolidaz düzeylerinin belirlenmesiiçin herhangi bir işlem uygulanmadan sakrifiye edildi ve kan örnekleri alındı. Grup 2 ve 3’de mezenterik iske- mi oluşturmak için basit laparotomi yapılarak, superiormezenterik arterler klemplendi. Grup 4 ve 5’de periferikiskemi oluşturmak için sağ ana femoral arter klemplenerek sırasıyla 120. ve 360. dakikalarda kan örneklerialındı. Tüm gruplardan elde edilen örneklerden serumprolidaz düzeyi ölçüldü.Bul­g u­l ar: Sıçanlardaki bazal prolidaz düzeyleri 266.8±20.5 U/L olarak bulundu. Periferik(404.0±105.6 U/L) ve mezenterik iskeminin(317.1±121.4 U/L) iki saat sonrasında serum prolidazaktiviteleri arttı. Ancak, periferik (346.1±104.9 U/L) ve mezenterik iskeminin (233.4±36.6 U/L) altı saat sonrasında serum prolidaz düzeyleri azaldı. Serum prolidazdüzeyleri mezenterik iskemide artmasında rağmen, bu periferik iskemide iki saat sonra elde edilen enzim düzeylerinden daha düşüktü (p=0.006). So­nuç: Serum prolidaz aktivitesi, iskemi süresininbelirlenmesinde önemli bir öngördürücü biyobelirteçolabilir.
