Abstract

Objective: Acute mesenteric ischemia is a challenging and fatal disease. The aim of this study was to detect the heat shock protein 32 (HSP32) response in intestinal tissue and systemic blood to intestinal ischemia and ischemia/reperfusion to define a tool for the early diagnosis of acute mesenteric ischemia. Material and Methods: Thirty female Wistar albino rats were equally divided into 3 groups. Group 1 rats underwent simple laparotomy and closure (control). In Group 2 rats, 1-hour intestinal ischemia followed by 5-hour reperfusion was performed, and Group 3 rats were subjected to 6-hour intestinal ischemia. The experiment was repeated with a 24-hour waiting period. At the end of the waiting period, blood was withdrawn from the tail veins of the rats and the rats were sacrificed via cardiac puncture. Re-laparotomy was subsequently performed and intestinal tissue and luminal samples were obtained for biochemical and pathological investigations. The HSP32 levels of intestinal tissues, luminal contents and blood levels were compared among the groups. Results: At the end of the 24-hour waiting period, the median tissue HSP32 levels were 0.43 (0-6.6) ng/mL for Group 1, 9.51 (2.5-49.9) ng/mL for Group 2 and 43.13 (6.3-121.3) ng/mL for Group 3 (p=0.001). The median blood HSP32 levels were 0.11 (0.1-1.4) ng/mL for Group 1, 0.42 (0.1-0.7) ng/mL for Group 2, and 0.25 (0.1-1.2) ng/mL for Group 3 (p=0.047). The HSP levels in the luminal contents were undetectable. Conclusion: Both ischemia and ischemia/reperfusion significantly raised intestinal tissue HSP32 levels in comparison with the control group. However, this change was not reflected in the circulating blood or luminal contents.

Özet

Amaç: Akut mezenterik iskemi zorlu ve ölümcül bir hastalıktır. Bu çalışmanın amacı iskemi/reperfüzyon ve intestinal iskemiye cevap olarak sistemik kan ve barsak dokusunda oluşan ısı şok protein 32 (HSP32) cevabını değerlendirerek, akut mezenterik iskeminin erken tanısında bir araç belirlemektir. Gereç ve Yöntemler: Otuz adet dişi Wistar-Albino cinsi sıçan 3 eşit gruba bölündü. Grup 1'deki sıçanlara basit laparotomi ve kapama işlemi uygulandı (kontrol). Grup 2'deki sıçanlara 1 saat iskemiyi takiben 5 saat reperfüzyon uygulandı ve Grup 3 deki sıçanlar 6 saat iskemiye tabi tutuldu. Deney 24 saatlik bekleme periyodunun sonunda tekrarlandı. Bekleme periyodunun sonunda sıçanların kuyruk veninden kan alındı ve sıçanlar kardiyak delme yöntemi ile sakrifiye edildi. Takiben tekrar laparotomi uygulandı ve biyokimyasal ve patolojik incelemeler için barsak doku ve lümen örnekleri elde edildi. Gruplar arasında barsak dokusundaki, lümen içeriğindeki ve kandaki HSP32 seviyeleri karşılaştırıldı. Bulgular: Yirmi dört saatlik bekleme süresinin sonunda ortalama doku HSP32 düzeyi grup 1'de 0.43 (0-6,6) ng/mL, Grup 2'de 9,51 (2,5-49,9) ng/mL ve Grup 3'te 43,13 (6,3-121,3) ng/mL idi (p=0,001). Ortalama kan HSP32 düzeyi Grup 1'de 0,11 (0,1-1,4) ng/mL, Grup 2'de 0,42 (0,1-0,7) ng/mL ve Grup 3'te 0,25 (0,1-1,2) ng/mL idi (p=0,047). Lümen içeriğindeki HSP düzeyleri belirlenememiştir.Sonuç: Hem iskemi hem iskemi/reperfüzyonda barsak doku HSP32 düzeyleri kontrol grubuna göre belirgin olarak yüksek bulundu. Ancak bu değişiklik dolaşan kan ve lümen içeriğine yansımamıştır.
