Abstract

AIM: Adiponectin plays an important role in the regulation of tissue inflammation. Recently, it has been reported that the plasma adiponectin levels in several acute illnesses decrease periodically, thus indicating that adiponectin may play a role in the inflammatory response in patients with acute illness. However, little is known about the effects of adiponectin following TBI. The aim of the present study was to examine the changes in the plasma adiponectin levels and the immunoreactivity of adiponectin in the brain after TBI. MATERIAL and METHODS: Adult male Sprague-Dawley rats were subjected to lateral fluid percussion injury using the Dragonfly device. Plasma adiponectin levels were determined by ELISA kit. Immunohistochemistry and Western blot analysis were performed to assess the immunoreactivity of adiponectin. results: The plasma adiponectin levels gradually decreased and were significantly lower at 48 h and 72h after injury than before injury. Immunohistochemistry and Western blot analysis showed that the adiponectin immunoreactivity was increased in the cerebral cortex at 24 hours after injury and in the hippocampus at 72 hours after injury. CONCLUSION: Our findings suggest that adiponectin might participate in the pathophysiological process occurring after TBI.

Özet

AMAÇ: Adiponektin doku enflamasyonunun düzenlenmesinde önemli bir rol oynar. Son zamanlarda plazma adiponektin düzeylerinin çeşitli akut hastalıklarda düzenli olarak azalması nedeniyle adiponektinin akut hastalığı olan hastalarda enflamatuvar cevapta bir rol oynayabileceği bildirilmiştir. Ancak travmatik beyin hasarı sonrasında adiponektin etkileri hakkında çok az şey bilinmektedir. Mevcut çalışmanın amacı travmatik beyin hasarı sonrasında plazma adiponektin düzeylerinin değişiklikleri ve beyinde adiponektin immünoreaktivitesini incelemekti. YÖNTEM ve GEREÇLER: Yetişkin erkek Sprague-Dawley sıçanlarında Dragonfly cihazları kullanılarak lateral sıvı perküsyon hasarı oluşturuldu. Plazma adiponektin düzeyleri ELISA kitiyle belirlendi. Adiponektin immünoreaktivitesini değerlendirmek üzere immünohistokimya ve Western blot analizi yapıldı. BULGULAR: Plazma adiponektin düzeyleri giderek azaldı ve yaralanmadan 48 saat ve 72 saat sonra yaralanma öncesine göre önemli ölçüde daha düşüktü. İmmünohistokimya ve Western blot analizi adiponektin immünoreaktivitesinin serebral kortekste yaralanmadan 24 saat sonra ve hippocampuste yaralanmadan 72 saat sonra arttığını gösterdi. SONUÇ: Bulgularımız adiponektinin travmatik beyin hasarı sonrasındaki patofizyolojik sürece katkıda bulunabileceğini düşündürmektedir.
