Objectives Oxidative stress, in which antioxidant proteins and scavenger protection are overwhelmed by reactive oxygen species (ROS) production, is recognized as one of central causes of disuse muscle atrophy. In this study, the hypothesis that oral treatment with Dangguibohyul-tang (Dangguibuxuetan...

불용성 근위축이란? | 오랜 기간의 침상생활이나 물리적 운동부족 등에 의한 근육량의 손실과 기능의 저하는 삶의 질의 저하 뿐 아니라 노령 환자의 사망률을 증가시키는 원인이 되기도 한다1).불용성 근위축(disuse muscle atrophy)이란 근육의 불사용 혹은 기능저하에 의해 근육이 위축되는 것을 말한다2).오랜 기간 근육을 사용하지 않게 되면 전신적으로 최대산소소모량, 심박출량, 정맥환류, 심근수축력 및 혈액용적이 감소하며 국소적으로 근위축이 초래된다. | |
근위축이 초래되는 원인은 무엇인가? | 불용성 근위축(disuse muscle atrophy)이란 근육의 불사용 혹은 기능저하에 의해 근육이 위축되는 것을 말한다2).오랜 기간 근육을 사용하지 않게 되면 전신적으로 최대산소소모량, 심박출량, 정맥환류, 심근수축력 및 혈액용적이 감소하며 국소적으로 근위축이 초래된다. 이러한 근위축은 주로 하지의 근육에서 뚜렷하게 나타나는 것으로 알려졌다3). | |
불용성 근위축이 주로 발생하는 위치는? | 오랜 기간 근육을 사용하지 않게 되면 전신적으로 최대산소소모량, 심박출량, 정맥환류, 심근수축력 및 혈액용적이 감소하며 국소적으로 근위축이 초래된다. 이러한 근위축은 주로 하지의 근육에서 뚜렷하게 나타나는 것으로 알려졌다3). 이전의 동물실험 연구결과에 따르면, 불용성 근위축 손상은 주로 여러 근섬유 유형이 혼합된 근육에서 유발되는데, 예를 들어 slow와 fast myosin-heavy chain을 모두 가지고 있는 gastrocnemius에서 흔히 나타나는 것을 볼 수 있다4). |
