description | Abstract Objective Traumatic brain injury (TBI) is a chronic, progressive condition associated with permanent disabilities, particularly cognitive impairments. Glial scar formation following TBI is considered a contributing factor to these persistent disabilities. Currently, limited research exists on pharmacological interventions targeting glial scar prevention that require a standard weight drop TBI model for glial scar formation. Since there is no established standard TBI model for glial scar formation, this study aims to validate and modify the height of the weight drop model to identify glial scar formation and cognitive impairments. Methods Fifteen male Sprague Dawley rats were randomly divided into sham, WD1, and WD2 groups. The weight drop model with a 10 g load was applied to the right exposed brain of the rats from a height of 5 cm (WD1) and 10 cm (WD2) using a modified Feeney’s weight drop device. Cognitive impairments were confirmed using the novel object recognition (NOR) test with ethovision software on day 15. Subsequently, the rats were decapitated on day 16, and GFAP immunohistochemical staining was performed to confirm the presence of glial scarring. Results The WD1 and WD2 groups exhibited a significant increase in glial scar formation compared to the sham group, with the WD2 group resulting in even more pronounced glial scar formation. Only the WD2 model caused statistically significant cognitive damage. The negative correlation coefficient indicates that an increase in GFAP + cells will decrease the cognitive function. Conclusion Modification of the height of the weight drop model, by dropping a weight of 10 g from a height of 10 cm (WD2 group) onto the right brain exposed of the rat has been proven to induce the formation of a glial scar and cognitive impairment. |
