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 (Dangguibuxuetang) could attenuate immobilization-induced skeletal muscle atrophy was tested. Methods The hindlimb immobilization was performed with casting tape to keep the left ankle joint in a fully extended position. The Rats in Dangguibohyul-tang treated group (DGBHT) (n=10) were orally administrated Dangguibohyul-tang water extract, and rats of Control group (n=10) were given with saline only. After 2 weeks of immobilization, the morphology of right and left gastrocnemius muscles in both DGBHT and Control groups were assessed by hematoxylin and eosin staining. Results Dangguibohyul-tang water extract represented the significant protective effects against the reductions of the left gastrocnemius muscles weight and average cross section area to compared with Control group. Moreover, the treatment with Dangguibohyul-tang extract significantly enhanced the Cu/Zn-SOD activities in gastrocnemius muscle compared with Control group. Conclusions Thses results suggest that Dangguibohyul-tang has protective effects against immobilization-induced muscle atrophy by increasing the Cu/Zn-SOD activities in gastrocnemius muscle.

This study was conducted to determine the effects of dietary glycine betaine on pork quality in different muscle types. A total of 80 female pigs ($Landrace{\times}Yorkshire{\times}Duroc$) were randomly allotted into one of four experimental diet groups. Each group of pigs were fed a commercial diet (Control) with 0.2 g glycine betaine (T1), 0.4 g glycine betaine (T2) and 0.6 g% glycine betaine (T3)/kg for 40 days. pH of belly was significantly higher in the control than dietary glycine betaine groups at 13 days of storage, whereas pH of picnic shoulder and ham were significantly lower in control than glycine betaine groups. At 13 days of storage, redness (a*) of belly was significantly higher in control than dietary glycine betaine groups, whereas picnic shoulder and ham were significantly higher in glycine betaine groups than in the control. Water-holding capacities (WHC) of all muscle samples were significantly higher in the control than glycine betaine groups until 5 days of storage. Sarcomere length was significantly longer in the control than glycine betaine groups. The thiobarbituric acid reactive substances (TBARS) value of belly was much higher than other muscle types at 13 days of storage. In fatty acid composition, dietary glycine betaine increased the ratio of saturated fatty acids (SFA) and decreased unsaturated fatty acids (USFA) in loins.

This study was conducted to evaluate the effects of a composite feed additive (CFA) consisting of vitamin C, vitamin E, selenium, and choline on growth performance, carcass characteristics, and meat properties of Hanwoo steers. Twenty-two late fattening steers were randomly assigned to one of two dietary groups, control (commercial concentrate + rice straw) and treatment (commercial concentrate + rice straw + 50 g of CFA). Average daily gain (ADG) was 4.0% higher in treatment than that in control; however, there was no statistically significant difference. The supplementation of CFA had no effect on overall yield or quality traits of carcass. CFA had no effect on chemical composition, water holding capacity, shear force, cooking loss, or myoglobin values in longissimus muscle; however, the content of ${\alpha}$-tocopherol was increased by supplementation of CFA (p < 0.01). The contents of ${\alpha}$-linolenic acid and n-3 fatty acids were higher in treatment group than in control (p < 0.01). The ratio of n-6/n-3 fatty acids was decreased by supplementation of CFA (p < 0.01). The supplementation of CFA had no effect on pH or thiobarbituric acid reactive substances (TBARS) values in longissimus muscle (raw); however, TBARS (cooked) values were lower in treatment group than in control during refrigerated storage (p < 0.01). Thus, the results indicate that the supplementation of CFA (vitamin C + vitamin E + selenium + choline) had some positive effects on the increase in ${\alpha}$-tocopherol and n-3 fatty in longissimus muscle, without any negative effect on growth performance or carcass characteristics of late fattening Hanwoo steers.

This study investigated the effects of green tea on the muscle antioxidative defense system in the white & red gastrocnemius muscles of rats after aerobic exercise. Male Sprague-Dawley rats weighing 150 10 g were randomly assigned to a control group, non-exercise with green tea group (G group), and exercise training group. The exercise training group was then further classified as the training (T) group and training with green tea (TG) group, the latter of which was supplemented with green tea in the drinking water during the experimental period. The rats in the exercise training groups (T and TG) were subjected to aerobic exercise on a treadmill 30 min/day at a speed of 28 m/min (7% incline) 5 days/week, while the other groups (control and G group) were cage confined for 4 weeks. Thereafter, the rats were sacrificed with an injected overdose of pentobarbital just after running. In the white muscle, the xanthine oxidase (XOD) activities were 71 % higher in the T group compared to control group, whereas the TG group had the same activity as the control group. The XOD activities in the red gastrocnemius muscle exhibited the same tendency as in the white muscle. The superoxide dismutase (SOD) activity in the white muscle was lower in the T group compared with the control group, yet significantly higher in the TG group compared with the T group. The SOD activities in the red gastrocnemius muscle exhibited the same tendency as in the white gastrocnemius muscle. The glutathione peroxidase (GSHpx) activities in the white & red gastrocnemius muscles were 43 % lower in the T group compared with the control group, yet the activities in the TG group remained at control levels. The glutathione S-transferase (GST) activity in the white muscle was not significantly different among any of the three groups, but in the red gastrocnemius muscle, the TG group had the same activity as in the control group. The thiobarbituric acid reactive substance (TBARS) contents in the white & red gastrocnemius muscles were higher in the T group than in the control but the control and TG groups had the same concentrations of TBARS. In conclusion, the supplementation of green tea in rats subjected to aerobic exercise was found to reduce the peroxidation of muscle lipids by enhancing the antioxidative defense mechanism.

The effects of brisk walking & muscle strengthening exercise on pain, fatigue, physical function & disease activity were examined in 28 patients with rheumatoid arthritis. Research design was a quasi-experimental study of non-equivalent control group pretest-posttest design. 14 for the experimental group and 14 for the control group were selected from the out patients on rheumatoid arthritis clinic of Dong-A University Hospital. The experimental group underwent 16 weeks of brisk walking and muscle strengthening exercise using Thera-Band. Pain, fatigue, physical function & disease activity was measured before and after 16 weeks of exercise. At baseline test, Fatigue & physical function score between groups were significantly different. So differences with in experimental group(baseline versus follow up) were compared with differences within the control group by Mann-Whitney test. There were significant differences between groups in the difference score on pain (U=6.50 p<.001) and fatigue (U=26.5 p<.01). For the experimental group, the score on the pain & fatigue was significantly decreased but no changed for the control group. Also there was a significant differences between groups in the difference score of the physical function (U=22.5 p<.001). For the experimental group, the score of the physical function has been significantly in creased. However, for the control group, it has been no changed. But there were no significant differences between groups in the ESR (erythrocyte sedimentation rate) and the CRP (C-reactive protein)level. In summary, brisk walking & muscle strengthening exercise led to significant improvements in pain, fatigue, and physical function without exacerbating disease activity in patients with rheumatoid arthritis.

Skeletal muscle atrophy can be defined as a decrease in or a disease of the muscle tissue, or as a disorder of the nerves that control the muscle, through injury or lack of use. This condition is associated with reactive oxygen species (ROS), resulting in various muscular disorders. Exposure to ROS induces muscle atrophy through several biological factors, such as SOD1 and HSP70. We found that cymbidium root extract reduced the $H_2O_2$-induced viability loss in C2C12 myoblasts and inhibited apoptosis. In addition, we showed that the cymbidium root extract increased the expression of HSP70 and decreased the expression of SOD1 in the $H_2O_2$-induced C2C12 myoblasts. These results suggest that cymbidium root extract might have therapeutic value in reducing ROS-induced muscle atrophy.

High-intensive endurance exercises induce cell changes in body, changes in structures and functions of the heart, the muscles, the cartilages, and the liver, as well as increase of inflammatory cytokine. The purpose of this study was to estimate the biochemical changes in the liver and muscles during ultra-marathon race (100 km) by sections. The blood of the subjects was collected before the marathon as a control in order to analyze serum creatine kinase (CK), lactic dehydrogenase (LDH), asprtate aminotransferase (AST), alanine aminotransferase (ALT), total(T)-bilirubin, direct(D)-bilirubin, total protein, albumin, uric acid, gamma-glutamyltranspeptidase (${\gamma}$-GTP), alkaline phosphatase (ALP), creatinine, blood urea nitrogen (BUN), and high sensitive C-reactive protein (hs-CRP) concentrations. The CK, LDH, D-bilirubin, AST and ALT concentrations at 50 km and 100 km were significantly increased compared to the control (P<0.05). The markers at 100 km were higher than those at 50 km (P<0.05). The T-bilirubin and hs-CRP concentrations showed no difference among the groups, whereas the markers at 100 km were higher than those of the control and at 50 km (P<0.05). In conclusion, this study shows that the ultra-marathon race (100 km) may induce the damage of the skeletal muscle, liver and kidney, intravascular hemolysis and inflammatory responses.

The incidence of type 2 diabetes mellitus and insulin resistance is growing rapidly. Multiple organs including the liver, skeletal muscle and adipose tissue control insulin sensitivity coordinately, but the mechanism of skeletal muscle insulin resistance has not yet been fully elucidated. However, there is a growing body of evidence that lipotoxicity induced by mitochondrial dysfunction in skeletal muscle is an important mediator of insulin resistance. However, some recent findings suggest that skeletal mitochondrial dysfunction generated by genetic manipulation is not always correlated with insulin resistance in animal models. A high fat diet can provoke insulin resistance despite a coordinate increase in skeletal muscle mitochondria, which implies that mitochondrial dysfunction is not mandatory in insulin resistance. Furthermore, incomplete fatty acid oxidation by excessive nutrition supply compared to mitochondrial demand can induce insulin resistance without preceding impairment of mitochondrial function. Taken together we suggested that skeletal muscle mitochondrial overloading, not mitochondrial dysfunction, plays a pivotal role in insulin resistance.

Phytic acid, making up 1~5% of the composition of many plant seeds and cereals, is known to form iron-chelates and inhibit lipid peroxidation. Thiobarbituric acid reactive substances (TBARS), as an indication of lipid peroxidation, were measured in beef round, chicken breast, pork loin, and halibut muscle after the meats were stored for 0, 1, 3, 5, and 7 days at various temperatures [frozen (~2$0^{\circ}C$), refrigerator (4$^{\circ}C$), and room temperature ($25^{\circ}C$)]. Phytic acid effectively inhibited lipid peroxidation in beef round, chicken breast, halibut, and pork loin muscle (p<0.05). The inhibitory effect of phytic acid was dependent on concentration, storage time, and temperature. At frozen temperature, the inhibitory effect of phytic acid was minimal, whereas at room temperature, the inhibitory effect of phytic acid was maximal, probably due to the variation of the control TBARS values. At the concentration of 10 mM, phytic acid completely inhibited lipid peroxidation in all the muscle foods by maintaining TBARS values close to the level of the controls, regardless of storage time or temperature (p<0.05). The rate of lipid peroxidation was the highest in beef round muscle, although they had a close TBARS value at 0 day. Addition of phytic acid to lipid-containing foods such as meats, fish meal pastes, and canned seafoods may prevent lipid peroxidation, resulting in improvement of the sensory quality of many foods and prolonged shelf-life.
