Abstract

Rhodiola sachalinensis A. Bor is a plant naturally grows in a high mountain areas. Aim of this study was to evaluate the effects of R.sachalinensis A. Bor extract against excessive exercise induced stress. R.sachalinensis A. Bor extract significantly inhibited L6 muscle cell death and ATP reduction caused by $H_2O_2$ damage. In addition, the oral administration of R. sachalinensis A. Bor extract in mice improved the 43.9% of treadmill running time and blood profiles of glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, lactate dehydrogenase, creatinine, lactate when compared to distilled water. These results suggested that R. sachalinensis A. Bor can attenuate excessive exercise induced damage.

본 연구결과에서 홍경천 추출물은 L6 근육세포에서 산화적 손상으로 인한 세포사멸과 ATP 생성량 감소를 유의적으로 억제하였을 뿐만 아니라 마우스에 2주간 200 mg/kg 농도로 경구투여시 통계적으로 유의하지는 않았으나 treadmill 운동시간을 증가시켰고 glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, lactate dehydrogenase, creatinine, lactate 등의 혈액지표를 개선시켰다. 따라서 홍경천은 과도한 운동 스트레스로 인한 손상을 억제할 수 있는 소재로써의 큰 가능성을 가지고 있는 것으로 판단된다.
