A moderate level of NF-κB immunopositivity was seen in Group 2and 3.Conclusion: Our results show that urapidil is one of theantioxidant agents and protects lung tissue from oxidanteffects of intestinal IR injury.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Objective: The effects of urapidil in intestinal ischemiareperfusion (IR) model were investigated using histopathological and biochemical methods.Materials and methods: Forty Wistar albino rats weresubjected to sham operation (Group 1), IR (Group 2),IR + dimethyl sulfoxide (Group 3), IR + urapidil 0.5 mg/kg(Group 4), and IR + urapidil 5 mg/kg (Group 5).
📊
Key Findings & Data:Levels ofMDA, TAS, TOS, SOD, MPO, NF-κB, caspase-3, and LC3Bwere measured.Results and discussion: The groups 2 and 3 had significantly higher TOS and MPO levels than the sham grouphad (p < 0.001), whereas the TAS and SOD levels weresignificantly lower in Group 2 than in the sham group.In treatment groups, TAS and SOD levels increased,whereas TOS, MPO, and MDA levels decreased comparedto Group 2.

Abstract

Objective: The effects of urapidil in intestinal ischemiareperfusion (IR) model were investigated using histopathological and biochemical methods.Materials and methods: Forty Wistar albino rats weresubjected to sham operation (Group 1), IR (Group 2),IR + dimethyl sulfoxide (Group 3), IR + urapidil 0.5 mg/kg(Group 4), and IR + urapidil 5 mg/kg (Group 5). Levels ofMDA, TAS, TOS, SOD, MPO, NF-κB, caspase-3, and LC3Bwere measured.Results and discussion: The groups 2 and 3 had significantly higher TOS and MPO levels than the sham grouphad (p < 0.001), whereas the TAS and SOD levels weresignificantly lower in Group 2 than in the sham group.In treatment groups, TAS and SOD levels increased,whereas TOS, MPO, and MDA levels decreased comparedto Group 2. Caspase-3 and LC3B immunopositivities wereseen at severe levels in Group 2 and 3. However, Group 4and 5 were found to have lower levels of immunopositivity.Immunopositivity was observed in interstitial areas, peribronchial region, and bronchial epithelial cells. A moderate level of NF-κB immunopositivity was seen in Group 2and 3.Conclusion: Our results show that urapidil is one of theantioxidant agents and protects lung tissue from oxidanteffects of intestinal IR injury.

Özet

Amaç: İntestinal iskemi-reperfüzyon (IR) modelinde urapidil’in etkileri histopatolojik ve biyokimyasal yöntemler kullanılarak araştırıldı. Gereç ve Yöntem: Kırk adet Wistar albino sıçan sham operasyon (Grup 1), IR (Grup 2), IR + dimetil sülfoksit (Grup 3), IR + urapidil 0.5 mg/kg (Grup 4) ve IR + urapidil 5 mg/kg (Grup 5) olarak gruplandı. MDA, TAS, TOS, SOD, MPO, NF-κB, kaspaz-3 ve LC3B seviyeleri ölçüldü. Bulgular ve tartışma: Grup 2 ve 3’te sham grubuna göre TOS ve MPO düzeylerinin anlamlı derecede yüksek, (p < 0.001), TAS ve SOD düzeyleri grup 2’de sham grubundan anlamlı derecede düşüktü. Tedavi gruplarında TAS ve SOD seviyeleri yükselirken, TOS, MPO ve MDA düzeyleri Grup 2’ye göre arttı. Kaspaz-3 ve LC3B immünopozitivitesi Grup 2 ve 3’te yoğun seviyelerde görüldü İnterstisyel bölgelerde, peribronşiyal bölgede ve bronşiyal epitel hücrelerinde immünopozitivite gözlendi. Grup 2 ve 3’te orta düzeyde bir NF-kappa B immünopozitivitesi görüldü. Sonuç: Sonuçlarımız urapidil’in, antioksidan ajanlardan biri olduğu ve akciğer dokusunu bağırsak IR hasarının oksidan etkilerinden koruduğunu göstermiştir.
