Characterization of a Rat Model of Blast-Induced mTBI: Pathophysiological Interplay of Primary and Tertiary Blast Many Service Members who sustain blast-induced TBI in combat are exposed to a brain insult resulting from a combination of both a shock wave (i.e., blast overpressure) and a biomechanical perturbation related to rapid acceleration and/or impact with a solid object. In this study, we tested the efficacy of WJ tissue transplantation in a weight-drop model of TBI in rats. Mathematical models differ greatly from in vivo and in vitro models, as cells are not usually required. Developmental Brain Research, 113, 13–20. All TBI rats appeared with arched back, erect hair, unconsciousness, and slow respiration but recovered to normal within the following 2 hours. Based on the Feeney DM TBI model in rats, we showed that ω-3 PUFA supplementation reduced brain edema and improved neurological scores.
