Abstract

BACKGROUND: We investigated the effects of iloprost and pentoxifylline on skeletal muscle ischemia-reperfusion injury in a rabbit model. METHODS: Forty New Zealand white rabbits were grouped into four. In Group 1, iloprost was continuously infused starting half an hour before the reperfusion following a 2-hour ischemia formed by abdominal aortic occlusion, and it was continued during the 4-hour reperfusion period. Group 2 was treated with pentoxifylline, and Group 3 received saline solution. Group 4 was the sham group. Malondialdehyde levels and edema scores in gastrocnemius muscle were evaluated. RESULTS: Edema score was significantly lower in Group 1 when compared with the control group (Group 1 vs Group 3, p=0.040; Group 2 vs Group 3, p=0.145; Group 1 vs Group 2, p=0.580). Malondialdehyde levels of the medicated groups were significantly lower when compared with the control group (Group 1: 60±11 nmol/g tissue, Group 2: 74±11 nmol/g tissue, Group 3: 95±10 nmol/g tissue; Group 1 vs Group 2, p=0.010; Group 1 vs Group 3, p<0.001; Group 2 vs Group 3, p<0.001; Group 1 vs Group 4, p<0.001; Group 2 vs Group 4, p<0.001; Group 3 vs Group 4: p<0.001). CONCLUSION: Acute skeletal muscle ischemia is a common problem. We are of the opinion that in the early phase of skeletal muscle ischemia, iloprost and pentoxifylline medication may reduce ischemia-reperfusion injury.

Özet

AMAÇ: Bu çalışmada, iloprost ve pentoksifilinin tavşan iskelet kasında iskemi reperfüzyon (IR) hasarı üzerine etkileri araştırıldı. GEREÇ-YÖNTEM: Kırk adet Yeni Zelanda cinsi beyaz tavşan her grupta 10 adet olacak şekilde dört gruba ayrıldı. Grup 1’de iloprost iki saat abdominal aort ve iliyak dallarının klemplenmesiyle oluşturulan iskemiyi takiben dört saatlik reperfüzyon boyunca infüzyon olarak verildi. Grup 2’ye pentoksifilin, Grup 3’e ise serum fizyolojik verildi. Grup 4 sham grubu idi. Gastroknemyus kasından malondialdehit düzeyi ve mikroskopik ödem skoru incelendi. BULGULAR: Grup 1’de kontrol grubuna göre mikroskoppik ödem skorlamasında anlamlı bir düşüklük saptandı (Grup 1 vs Grup 3, p=0,040; Grup 2 vs Grup 3, p=0,145; Grup 1 vs Grup 2, p=0,580). Malondialdehit düzeyleri bakımından Grup 1 ve Grup 2’de kontrol grubuna kıyasla anlamlı bir düşüklük saptandı (Grup 1: 60±11 nmol/gr, Grup 2: 74±11 nmol/gr, Grup 3: 95±10 nmol/gr, Grup 4: 29±7 nmol/gr) (Grup 1 vs Grup 2, p=0,010; Grup 1 vs Grup 3, p<0,001; Grup 2 vs Grup 3, p<0,001; Grup 1 vs Grup 4, p<0,001; Grup 2 vs Grup 4, p<0,001; Grup 3 vs Grup 4: p<0,001). SONUÇ: İskelet kası akut iskemisi sık bir klinik sorundur, erken dönemde iloprost ve pentoksifilin tedavisinin IR hasarını azaltabileceği görüşündeyiz.
