Chronic alcoholic myopathy is one of the most common skeletal muscle disorders. It is characterized by a reduction in the entire skeletal musculature, skeletal muscle weakness, and difficulties in gait. Patients with alcoholic hepatitis and cirrhosis have severe muscle loss that contributes to worsening outcome. Although the myopathy selectively affects Type II (fast twitch, glycolytic, anaerobic) skeletal muscle fibers, total skeletal musculature is reduced. The severity of the muscle atrophy is proportional to the duration and amount of alcohol consumed and leads to decreased muscle strength. The mechanisms for the myopathy are generally unknown but it is not due to overt nutritional deficiency, nor due to either neuropathy or severe liver disease. Skeletal muscle mass and protein content are maintained by a balance between protein synthesis and breakdown and in vivo animal models studies have shown that ethanol inhibits skeletal muscle protein synthesis. Daekumeumja is a traditional Korean medicine that is widely employed to treat various alcohol-induced diseases. Muscle diseases are often related to liver diseases and conditions. The main objective of this study was to assess that Daekumeumja extract could have protective effect against alcoholic myopathy in a Sprague-Dawley rat model. Rats were orally given 25% ethanol (5ml/kg, body weight) for 8 weeks. After 30 minutes, rats were administrated with Daekumeumja extract. Controls were similarly administrated with the vehicle alone. The weights of gastrocnemius, soleus and plantaris muscles were assessed and the morphologic changes of gastrocnemius and plantaris muscles were also assessed by hematoxylin and eosin staining. In results, The muscles from ethanol treated rats displayed a significant reduction in muscle weight and average cross section area compared to Normal group. Daekumeumja extract treated group showed increased muscle weight and muscle fiber compared to the ethanol treated group. It was concluded that Daekumeumja extract showed ameliorating effects on chronic alcohol myopathy in skeletal muscle.
