Objectives: This study was carried out to observe the foot gworeum meridian muscle from a viewpoint of human anatomy on the assumption that the meridian muscle system is basically matched to the meridian vessel system as a part of the meridian system, and further to support the accurate application of acupuncture in clinical practice. Methods: Meridian points corresponding to the foot gworeum meridian muscle at the body surface were labeled with latex, being based on Korean standard acupuncture point locations. In order to expose components related to the foot gworeum meridian muscle, the cadaver was then dissected, being respectively divided into superficial, middle, and deep layers while entering more deeply. Results: Anatomical components related to the foot gworeum meridian muscle in human are composed of muscles, fascia, ligament, nerves, etc. The anatomical components of the foot gworeum meridian muscle in cadaver are as follows: 1. Muscle: Dorsal pedis fascia, crural fascia, flexor digitorum (digit.) longus muscle (m.), soleus m., sartorius m., adductor longus m., and external abdominal oblique m. aponeurosis at the superficial layer, dorsal interosseous m. tendon (tend.), extensor (ext.) hallucis brevis m. tend., ext. hallucis longus m. tend., tibialis anterior m. tend., flexor digit. longus m., and internal abdominal oblique m. at the middle layer, and finally posterior tibialis m., gracilis m. tend., semitendinosus m. tend., semimembranosus m. tend., gastrocnemius m., adductor magnus m. tend., vastus medialis m., adductor brevis m., and intercostal m. at the deep layer. 2. Nerve: Dorsal digital branch (br.) of the deep peroneal nerve (n.), dorsal br. of the proper plantar digital n., medial br. of the deep peroneal n., saphenous n., infrapatellar br. of the saphenous n., cutaneous (cut.) br. of the obturator n., femoral br. of the genitofemoral n., anterior (ant.) cut. br. of the femoral n., ant. cut. br. of the iliohypogastric n., lateral cut. br. of the intercostal n. (T11), and lateral cut. br. of the intercostal n. (T6) at the superficial layer, saphenous n., ant. division of the obturator n., post. division of the obturator n., obturator n., ant. cut. br. of the intercostal n. (T11), and ant. cut. br. of the intercostal n. (T6) at the middle layer, and finally tibialis n. and articular br. of tibial n. at the deep layer. Conclusion: The meridian muscle system seemed to be closely matched to the meridian vessel system as a part of the meridian system. This study shows comparative differences from established studies on anatomical components related to the foot gworeum meridian muscle, and also from the methodical aspect of the analytic process. In addition, the human foot gworeum meridian muscle is composed of the proper muscles, and also may include the relevant nerves, but it is as questionable as ever, and we can guess that there are somewhat conceptual differences between terms (that is, nerves which control muscles in the foot gworeum meridian muscle and those which pass nearby) in human anatomy.

The Purpose of this study is to investigate the effect of soluble dietary fiber psyllium on insulin sensitivity and skeletal muscle glucose transporter 4(GLUT4) protein expression in stroke-prone hypertensive rats(SHRSP) fed a high-fat diet containing 5% of psyllium or cellulose from five to nine weeks of age. Obtained results were as follows : (1) In the psyllium diet group fasting plasma glucose level was significantly reduced and glucose levels upon oral glucose tolerance test were significantly lower than cellulose diet group at 30 min(p<0.05) and 60 min(p<0.01) (2) Skeletal muscle GLUT4 contents were significantly increased in the soleus(slow twitch) and extensor digitorum longus(fast twitch) muscle of psyllium diet group. (3) However there was no difference in insulin levels in the fasting and oral glucose tolerance test. These results indicated that psyllium diet improves peripheral insulin sensitivity but not insulin secretion. In conclusion our present finding suggest that soluble fiber diet is effective to increase insulin sensitivity in SHRSP. From these results it was suggested that soluble dietary fiber supplementation effectively prevents insulin resistance.

Fiftysix male weanling rats of the Sprague-Dawley strain weighing $52.6{\pm} 0.9g$ were fed with 77% starch-15% casein diet by ad libitum for four days to get them adapted and divided into eight groups. For three weeks, the body weight gain of rats was controlled in three different ranges. After the period of food restriction, the rats were recovered by being fed by ad libitum for seventeen days. During the experimental period, the amount of food intake and body weight were measured. And the experimental groups were compared when they reached at the same age and at the same body weight. Anterior Tibialis, Extensor Digitorum Longus, Soleus, Plantaris, Gastrocnemius were used as analytic items of skeletal muscle. Wet weight of muscle, muscle protein, water content were measured from each of five skeletal muscles. Sodium, potassium, magnesium content were measured from Anterior Tibialis, Extensor Digitorum Longus, Soleus ana Plantaris. Phosphorus was measured only from Gastrocnemius. The whole carcass protein except the skeletal muscles was also measured. During the period of food restriction, food intake was $311.7{\pm}19.5g$ for the control group. $130.2{\pm}1.5g$ for the second group and $161.7{\pm}2.1g$ for the third group. During the period of food restriction, body weight gain was $106.8{\pm}12.7g$ for the control group, $3.6{\pm}2.1g$ for the second group and $18.9{\pm}3.3g$ for the third group. Comparing the body weight when they reached at the age 66 days, the control group showed higher value than the other groups. In the concentration of electrolytes of skeletal muscles sodium and magnesium tend to increase and potassium and phosphorus tend to decrease by food restriction. But after their recovery, there was no significant difference between the groups. By the degree of food restriction, there was time difference in reaching at the same body weight. But when they reached at the same body weight, there was no significant difference in the value of electrolytes concentration. Regarding all the results of this study, the ages of rats which reached the same body weight were different by food restriction level during weanling. Once food·restricted rats reached the same body weight by recovery, the concentration of electrolytes and protein tend to become almost the same.

Purpose: Pollicization typically involves surgical migration of the index finger to the position of the thumb. This procedure facilitates the conversion of a useless hand into a well-functioning one in patients who are not amenable to the toe-to-hand transfer. However, middle finger pollicization has been rarely reported. Materials and Methods: We reconstructed a thumb by immediate pollicization of the remnants of the middle finger in two patients who sustained a tumor and a trauma, respectively. The former, after cancer ablation was performed, has not been reported literally, and the latter involved free devitalized pollicization of the middle finger using a microsurgical anastomosis. The distal third extensor communis tendon was sutured to the proximal extensor pollicis longus tendon and the distal flexor digitorum superficialis and profundus were sutured to the proximal flexor pollicis longus. The abductor pollicis brevis tendon was sutured to the distal end of the first palmar interosseous muscle. Coaptation of the third digital nerve and the superficial radial nerve branch was performed. Results: Patients showed uneventful postoperative courses without complication such as infection or finger necrosis. Based on the principles of pollicization, a wide range of pinch and grasp movements was successfully restored. They were pleased with the functional and cosmetic results. Conclusion: Although the index finger has been the digit of choice for pollicization, we could also use the middle finger on specific occasions. This procedure provides an excellent option for the reconstruction of a mutilated thumb and could be performed advantageously in a single step.

Background: Sarcopenia is a new and emerging risk factor aggravating the quality of life of elderly population. Because Korean Red Ginseng (RG) is known to have a great effect on relieving fatigue and enhancing physical performance, it is invaluable to examine its potential as an anti-sarcopenic drug. Methods: Anti-sarcopenic effect of non-saponin fraction of Korean Red Ginseng (RGNS) was evaluated in C2C12 myoblasts treated with C2-ceramide to induce senescence phenotypes, and 22-month-old mice fed with chow diet containing 2% RGNS (w/w) for 4 further months. Results: The RGNS treatment significantly alleviated cellular senescence indicated by intracellular lipid accumulation, increased amount of lysosomal β-galactosidase, and reduced proliferative capacity in C2C12 myoblasts. This effect was not observed with saponin fraction. In an aged mouse, the 4-month-RGNS diet significantly improved aging-associated loss of muscle mass and strength, assessed by the weights of hindlimb skeletal muscles such as tibialis anterior (TA), extensor digitorum longus (EDL), gastrocnemius (GN) and soleus (SOL), and the cross-sectional area (CSA) of SOL muscle, and the behaviors in grip strength and hanging wire tests, respectively. During the same period, an aging-associated shift of fast-to slow-twitch muscle in SOL muscle was also retarded by the RGNS treatment. Conclusions: These findings suggested that the long-term diet of RGNS significantly prevented aging-associated muscle atrophy and reduced physical performance, and thus RGNS has a strong potential to be developed as a drug that prevents or improves sarcopenia.

Skeletal muscle injury occurs frequently in sports medicine and is the most general form of injury followed by physical impact. There are growth factors which conduct proliferation, differentiation, and synthesis of myogenic prodromal cells and regulate vascular generation for the continued survival of myocytes. The purpose of the present study was to confirm the effects of electroacupuncture (EA) and electrical stimulation (ES) on muscle recovery processes according to vascular endothelial growth factor (VEGF) expression. Eighteen Sprague-Dawley rats were separated into 2 experimental groups and a controlled group. All animals had suffered from crush damage in the extensor digitorum longus for 30 seconds and were killed 1, 3, and 7 days after injury. 30 Hz and 1 mA impulsion for 15 minutes was applied to the EA experimental groups Zusanli (ST36) and Taichong (LR3) using electroacupuncture and the same stimulation was applied to the ES group using an electrical node. Hematoxyline-Eosin staining and VEGF immunohistochemistry were used to ascertain the resulting muscle recovery. There were few morphological differences between the EA and ES groups, and both groups were observed to have tendencies to decrease atrophy as time passed. In the controlled group, gradually diminishing atrophy could be observed, but their forms were mostly disheveled. There were few differences in VEGF expression between the EA and ES groups, and tendencies to have an increased quantity of VEGF with the lapse of time were observed in both groups. In the controlled group, a little VEGF expression could be observed merely 7 days after injury. In conclusion, EA and ES contributed to muscle recovery processes and could be used for the treatment of muscle injury.

Background: Ankle evertor muscles are important for preventing lateral ankle sprain. Since, the evertor muscles cross the ankle and toe joints, the position at which the ankle evertor muscle strength is measured is important. However, no studies have previously investigated the effect of ankle and toe positions on the strength of the ankle evertor muscle. Objects: This study is aimed to determine the effect of various ankle and toe joint positions on the strength of the ankle evertor muscles in healthy subjects. Methods: Eighteen healthy subjects participated in this study. Isometric ankle evertor strength of the dominant leg was determined in each subject in different ankle and toe positions (dorsiflexion (DF) with toe extension (TE), DF with toe flexion (TF), plantar flexion (PF) with TE, and PF with TF). A 2 by 2 repeated analysis of variance (ANOVA) was used to determine the difference in the evertor strength between the ankle positions (PF and DF) and toe positions (TE and TF). Results: The results indicate that there was no significant ankle position by toe position interaction effect (p=.83). However, the ankle evertor strength was significantly increased in the ankle DF position than in the PF position (p<.01), and the ankle evertor strength during eversion with TE was significantly higher than eversion with TF (p<.01). Conclusion: The findings of this study suggest that clinicians should consider the ankle and toe positions when measuring the muscle strength and during performance of selective muscle strengthening exercises of the ankle evertor muscles.

Objectives Although many studies explored the topic of meridian sinew in various perspectives and the term "meridian sinew" is widely used, the theory of meridian sinew is not applied for precise diagnosis and in-depth treatment in clinical practice. The aim of the study is to provide basic data classifying muscles into meridian sinew for future studies that investigate meridian sinew based on an anatomical basis. Methods Studies were identified with searches of six major Korean databases: OASIS, KoreaMed, KMBASE, KISS, NDSL and KoreanTK. Published primary studies classifying muscles into meridian sinew were included. Results A total of 20 studies met the inclusion criteria and were included in the analysis. Twelve studies conducted the classification of muscles into meridian sinew based on meridian/ acupoints distribution and six based on meridian sinew distribution, and two based on both. Muscles with fidelity level of 50 or more were 54 (85.7%) and muscles with 100 fidelity level were 7 (11.3%): occipitalis, adductor digiti minimi, frontalis, biceps femoris, rectus femoris, vatus lateralis and extensor digitorum longus. Conclusions Classification results of muscles into meridian sinew varied according to the classification criteria and interpretation of meridian sinew and acupoints distribution. To develop muscle sinew as a more useful theory in diagnosis and treatment, efforts should be made to reduce the gap between study results and build consensus on the anatomical entity of meridian sinew.

In oriental medicine, it is known that Eucommiae Cortex (EC) has strengthening and rehabilitative effects on the bone-muscle dysfunction. This study aimed to evaluate the effect of EC on the skeletal muscle atrophy. The muscle atrophy was induced by unilateral transection of the sciatic nerve in Sprague-Dawley rats. EC (water-extract, 170mg/100 g body weight) was treated once a day for 12 days. In this study, the effect of EC examined the muscle weight of hind limb, cross section areas of muscle fibers, fiber type compositions, apoptosis related factors (Bax and Bcl-2). EC reduced muscle atrophy in soleus (SOL), medial gastrocnemius (MGT), extensor digitorum longus, and tibialis posterior significantly in the damaged hind limb. EC increased type-I muscle fibers and decreased type-II muscle fibers significantly in SOL of the damaged hind limb. EC enlarged cross section areas of type-I and type-II muscle fibers significantly in SOL. EC enlarged cross section areas of type-I and type-II muscle fibers significantly in. EC reduced apoptotic nuclei and atrophic muscle fibers in SOL and MGT. EC reduced Bax positive muscle nuclei in SOL and MGT. EC up-regulated Bcl-2 positive muscle fibers in SOL and MGT. These results suggest that EC has an anti-atrophic effect and anti-apoptotic effect against myonuclear apoptosis induced by the peripheral nerve damage.
