Purpose: This study was conducted to investigate the functional differences of the two heads of the biceps brachii by measuring the functions in supination according to pronation by the angle of the flexion of the elbow joint, except for the activities of the elbow flexors. Methods: This study was conducted with 25 healthy men in their 20s. At a glenohumeral-joint 0˚ flexion posture, angles of flexion of the elbow joint of 0˚, 30˚, 60˚, 90˚, and 120˚ were randomly provided, and they were asked to perform supination and pronation with an elastic band. Using an eight-channel surface electromyogram, the muscle activities of the long and short heads of the biceps brachii were measured. The activities of the short and long heads according to the angle were analyzed using a one-way ANOVA, and as a post-test, LSD was employed. Results: The analysis of the impact of the resistance of the elastic band in supination on the differences in the muscle activities in the short and long heads suggests there was a significant difference between 0˚ and 30˚ (p < 0.05). Conclusion: In supination according to forearm pronation, the long head had greater action in the early flexion posture of the elbow joint, and it is judged that the ratio of the flexion of the elbow joint according to the actions of the biceps brachii was considered small.

Since successive operations under the acupuncture analgesia have been reported In China 1971, veterinary acupuncture was brought to the attention over the world and then its research and clinical use have markedly developed. Veterinary acupuncture and moxibustion was originated in China and Korea, but the research activities on them were not very significantly advanced. In this study, status of veterinarians on veterinary acupuncture and moxibustion, acupunctures which has been practiced by civil acupuncturist, therapeutic effects of acupuncture for the animal diseases in the field, and effects of electric acupuncture on the lumen motility in ruminants, etc. were Investigated. One-fifty of veterinarians of private clinics in Korea was interested in acupuncture and moxibustion in veterinary medicine. A lot of veterinarians required the scientific, systemic technique and knowledge or acupuncture. Civil acupuncturists who have been practiced acupuncture and moxibustion were 20 persons, and most of them were very old. They used chiefly three edged needles which were made by themselves and utilized old traditional technique in which the acupoints were stimulated and bled. Treatment with acupuncture for the digestive, muscular locomotive and febrile diseases was very effective. Until nowadays, the research on veterinary acupuncture in Korea has not much progressed. However, the Korean Societh of Veterinary Acupuncture and Moxibustion was organized in 1990. Valuable development for acupuncture through the society are expected. Electroacupuncture regional analgesia on the combinations of Yao-Pang 1, 2 and 4 acupoints was very effective for abdominal operations in cattle. But a lot of experiences and studies on the acupuncture anesthesia were required for clinical use in the future. Therapeutic effects of about 80% were obtained from electroacupuncture on the combinations of Tian Ping-Bai Hui-Shi Zhang, and Guan Yuan Yu acupoints in cattle with luminal atony and tympany In the field. Electroacupuncture on the combination of Tian Ping-Bai Hui-Qi Men, and Tian Ping-Bai Bui-Wei Gen for the treatment of downer cow was not so effective. The effects of stimulation and bleeding from acupoint by three edged needle was excellent for febrile diseases. The luminal contractile movement was accentuated by electroacupuncture on Tian Ping-Bai Hui-Shi Zhang combination and Guan Yuan Yu acupoint. It was concluded that veterinary acupuncture and moxibustion should be utilized for veterinary practice, and the advanced scientific research and clinical experiences must be followed.

Peripheral nerve injury occurs mostly by trauma and is usually associated with fracture of bone and joint, muscular injury and tendon injury and it also evokes paralysis and anesthesia. When treatment of peripheral nerve injury is considered,, the modality of treatment is decided by the general condition of the patient, type of injury, associated injuries and the condition of wound. To get the maximum results, surgical treatment and reconstruction and rehabilitation should all go in hand-in-hand. From January 1985 to December 1994, we observed 61 patients that had operation without reconstruction due to peripheral nerve injury with a follow-up period of more than 1 year. Among the 61 patients, 44 were men(72%) and 17 were women(28%). Follow-up period was average 19 months. Age distribution was mostly in their twenties with a mean age of 28 years. Time interval of operation after injury was average 11 months. Trauma was the main cause of peripheral nerve injuries with a proportion of 87%. 31 patients had neurorrhaphy, in which case 14 patients had stay suture and 17 patients did not. 14 patients had nerve graft, and 16 patients had neurolysis. We used our scales to compare the results of surgery on the basis of British Research Council System. We gave scores to every sensory and motor scale to estimate functional improvement and emphasized on motor functional improvement. The total score = sensory score + ($2{\times}motor$ score). We considered 8-9 points as excellent, 6-7 points as good, 2-5 points as fair, 0-1 points as poor result. We considered excellent and good as much improved. Excellent and good results were obtained in 13 out of 14 neurorrhaphy with stay suture(93%), 12 out of 17 neurorrhaphy without stay suture(71%), 6 out of 14 nerve graft(43%), 12 out of 16 neurolysis(75%). Among the patients with neurorrhaphy done within 3 months, 11 out of 14(86%) showed improvement, but among the patients after 4 months 3 out of 17(76%) showed improvement. 84% of improvement was observed in the patients with time interval from injury to surgery within 3 months, and 64% in the patients with time interval after 4 months. In the aspect of age, 77% with the age below 20 years, 70% with the age between 21 and 30 years, 66% with the age above 31 years showed improvement. We conclude that considering degree of injury, time interval from injury and age with the adequate method of treatment, we can obtain good results from surgery.

Purpose: There are many articles describing about Guyon canal compression syndrome. Until recently, most of these articles have been presented about the symptoms of ulnar nerve compression, but there have been no reports about ulnar artery compression. In this article, besides the nerve compression symptoms in the Guyon's canal, we represented the symptoms and treatments based on the ulnar artery obstruction. Methods: Guyon canal is composed of the hamate and pisiform, and the ligaments which connect them. The course of the ulnar nerve and artery, which passes through this narrow canal, is affected by the anatomical structure of the base of the canal. Out of 14 patients (21 cases) were retrospectively reviewed in this study from 2006 to 2009. Of 14 patients, there were 5 men and 9 women with ages between 21 to 61 years old. The symptoms had volar sensory loss of ulnar sided digits, with muscular atrophy of hypothenar muscles. Prior to surgery, most of these patients had vascular disorders which was diagnosed definitively by angiography and electromyogram. Results: The release of Guyon canal and interposition graft of the obstructed arteries was carried out to 11 patients (15 cases) who had artery (vascular) occlusive disorder, and. 12 cases had sympathectomy and interposition graft after resection of obstructed ulnar artery. Six cases had release of carpal tunnel performed simultaneously. There were no major complications after surgery. The circulation of the ulnar artery was improved along with the patients' symptoms. Conclusion: The pre-existing articles about Guyon canal compression syndrome were mainly focused on ulnar nerve compression. This study, which was carried out by our department, showed that most of these patients had ulnar artery obstruction or stenosis simultaneously with ulnar nerve compression. The vascular disorder was corrected by interposition graft after the resection of the site of ulnar artery occlusion. And to conclude, When we resolve the ulnar nerve compression, the proper diagnosis & treatment of impaired ulnar artery circulation should be carried out concomitantly.
