In this study, we investigated the effects of EGCG on cerebral function and morphology following TBI. 24-month-old rats male Wistar rats that had access to normal drinking water, or water containing 0.1% (w/v) EGCG ad libitum, received TBI with a pneumatic controlled injury device for 4weeks. Immunohistochemistry and lipid peroxidation studies revealed that at 1, 3 and 7 days post-TBI, the number of 8-OHdG-, 4-HNE- and ssDNA-positive cells, and the levels of MDA around the damaged area after TBI, significantly decreased in the EGCG treatment group compared with the water group. In addition, there was a significant increase in the number of surviving neuronal cells and an improvement in cerebral dysfunction after TBI in the EGCG treatment group compared with the water group. In summary, consumption of green tea may be an effective therapy for TBIaged patients., 研究種目:基盤研究(C); 研究期間:2015~2017; 課題番号:15K00898; 研究分野:神経病理学; 科研費の分科・細目:, application/pdf}, title = {緑茶が及ぼす加齢ラット脳外傷後の脳機能改善効果及び神経再生促進効果に関する研究}, year = {2018}, yomi = {サトウ, タカオ and イトウ, タツキ and イノウエ, タカオ} }
