摘要

Purpose

Traumatic brain injury (TBI) is a condition characterized by structural and functional damage to the brain following trauma and is a significant cause of mortality. Acute kidney injury (AKI) has been reported in patients with TBI and is a commonly encountered complication. This study examines the effect of tasimelteon (Tasi) application on kidney tissue in TBI rats by histopathological and immunohistochemical staining.

Methods

Forty male Wistar Albino rats weighing 300–350 g were randomly divided into four groups: Control group, Trauma group (Trau), Trau-Tasi-1 group (trauma-1 mg/kg Tasi intraperitoneally), and Trau-Tasi-10 group (trauma-10 mg/kg Tasi intraperitoneally). At the end of the experimental phase, after euthanasia, kidney tissue was collected for histopathological and immunohistochemical analyses.

Results

The results of histopathological and immunohistochemical staining demonstrate that brain trauma may induce kidney injury, while Tasi possesses the potential to ameliorate kidney lesions associated with TBI. It has been found that Trau-Tasi-10 is more effective in treatment compared to Trau-Tasi-1.

Conclusion

We observed Tasi’s kidney injury ameliorating activity in TBI rats through histopathological and immunohistochemical staining findings.
