ABS TRACT Ob jec ti ve: Mild tra u ma tic bra in in jury (MTBI) is one of the most fre qu ent ne u ro lo gi cal da ma ge types in which comp lex physi o lo gi cal and bi oc he mi cal events oc cur in tra u ma ti zed are a. Re gi o nal isc he mi a can oc cur in the acu te pha se af ter tra u ma. Re cently, both cli ni cal and ex pe ri men tal stu di es ha ve shown that isc he mi a mo di fi ed al bu min (IMA) is one of the most pro mi sing blo od mar kers of isc he mi a. In this study, whet her se rum IMA va lu es can be used in rats as a mar ker for in trac ra ni al isc he mi a ca u sed by tra u ma is investigated. Ma te ri al and Met hods: Wis taral bi no adult rats we re uti li zed in this study. Rats we re ex po sed to MTBI by using a tra u ma de vi ce. Fron tal and pa ri e tal bra in tis su es we re ta ken for his to pat ho lo gi cal in ves ti ga ti on. Se rum IMA va lu es of tra u ma ti sed and con trol rats we re me a su red with the ACB (al bu min co balt bin ding) test. Re sults: Whi le the ab so lu te IMA va lu es we re 0.576 ± 0.048 for tra u ma gro up, it was iden ti fi ed as 0.568 ± 0.055 for con trol gro up.
