The results suggested that intravitreal application of a single dose of 1 mg/0.1 ml BSA solution may induce a significant posterior uveitic reaction both angiographically and histopathologically.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:We aimed to perform histopathological analysis of models of experimental uveitis (EU) induced with bovine serum albumin (BSA) solutions at various doses in order to determine the most appropriate dose of BSA.
📊
Key Findings & Data:Three different BSA solutions were prepared: 100 µg/0.1 ml, 1 mg/0.1 ml and 10 mg/0.1 ml BSA solutions were applied intravitreally to the first rabbit, second rabbit and third rabbit respectively.
💡
Conclusion & Impact:The results suggested that intravitreal application of a single dose of 1 mg/0.1 ml BSA solution may induce a significant posterior uveitic reaction both angiographically and histopathologically.

Abstract

We aimed to perform histopathological analysis of models of experimental uveitis (EU) induced with bovine serum albumin (BSA) solutions at various doses in order to determine the most appropriate dose of BSA. Right eyes of four rabbits were used. Three different BSA solutions were prepared: 100 µg/0.1 ml, 1 mg/0.1 ml and 10 mg/0.1 ml BSA solutions were applied intravitreally to the first rabbit, second rabbit and third rabbit respectively. Fourth rabbit was used as control. Uveitis formation was followed clinically and angiographically. Rabbits were sacrificed and eyes were enucleated at the end of the first week for histopathological analysis. In the first rabbit, mild anterior uveitic signs were seen. In the second rabbit, there was a moderate inflammation in the vitreous, retina and choroidea, as well as severe inflammatory cell infiltration in the ciliary tissue. In the third rabbit, there was a severe inflammatory reaction and congestion in the ciliary tissue. Severe inflammatory cell infiltration in the vitreous, retina and choroidea was also seen. The results suggested that intravitreal application of a single dose of 1 mg/0.1 ml BSA solution may induce a significant posterior uveitic reaction both angiographically and histopathologically.

Özet

Çalışmamızda, farklı dozlarda sığır serum albümin (SSA) çözeltileri ile indüklenen deneysel üveit modellerinin histopatolojik analizi gerçekleştirilerek en uygun dozun belirlenmesi amaçlanmıştır. Çalışmada 4 tavşanın sağ gözleri kullanıldı. Üç farklı SSA çözeltisi hazırlandı: 100 µg/0.1 ml, 1 mg/0.1 ml ve 10 mg/0.1 ml SSA çözeltileri sırasıyla tavşan 1, 2 ve 3'e intravitreal yoldan uygulandı. Tavşan 4 kontrol olarak kullanıldı. Üveit oluşumu klinik ve anjiyografik olarak takip edildi. Bir hafta sonra tavşanlar sakrifiye edildi ve gözler histopatolojik analiz için enükle edildi. Tavşan 1'de hafif ön üveit bulguları görüldü. Tavşan 2'de vitreus, retina ve koroidde orta düzeyde enflamasyon varken siliyer cisimde yoğun enflamatuar hücre infiltrasyonu vardı. Tavşan 3'de siliyer cisimde ciddi düzeyde enflamatur reaksiyon ve konjesyon vardı. Ayrıca vitreus, retina ve koroidde de yoğun enflamatuar hücre infiltrasyonu görüldü. Sonuç olarak, 1 mg/0.1 ml SSA çözeltisinin tek doz intavitreal uygulanması anjiyografik ve histopatolojik olarak anlamlı düzeyde arka üveitik reaksiyon oluşturabilir.
