It has been reported that boron may be beneficial for optimal calcium metabolism and, thus, optimal bone metabolism. Therefore, we designed a study to determine the effect of boron supplementation on Ca and bone metabolism in rats. The rats of 80-l40g body weight were given a control(0ug), 5$\mu\textrm{g}$, 10$\mu\textrm{g}$, 20$\mu\textrm{g}$, 40$\mu\textrm{g}$, or 80$\mu\textrm{g}$ boron supplement per Is diet for 4-weeks. The results are summarized as follows. There were no differences in total food intake and weight gain among the experimental groups. fecal Ca excretion, urinary Ca excretion, apparent Ca absorption, Ca retention, serum alkaline phosphatase activity, and urinary hydroxyproline were not affected by boron supplementation. There was no difference in serum creatinine. Whereas, urinary creatinine excretion was increased with increasing boron supplementation, and conse-quently creatinine clearance was increased with boron supplementation. No differences were found in length, weight, density, Ca content of femur and scapular. The findings suggest that boron supplementation was not effective in Ca and bone metabolism in growing rats fed normal Ca diet. (Korean J Nutrition 31(6) : 1039-1048, 1998)

PURPOSE: The purpose of this study was to compare the muscle architecture of serratus anterior and lower trapezius using rehabilitative ultrasound imaging (RUSI) in affected and unaffected side of chronic stroke patients. METHODS: The participants were thirty five patients with stroke hemiplegia in this study. RUSI was used to measure the muscle thickness of the serratus anterior and lower trapezius muscles. We compared the muscle thickness according to affected side and sex, determined the reliability of the measurement image. Independent t-test, intra-class correlation coefficient (ICC) and standard error of measurement (SEM) were used for statistical analysis. RESULTS: Significant difference in muscle thickness of serratus anterior was observed between affected and unaffected side (p<.001). Muscle thickness according to gender showed a significant difference in unaffected side of serratus anterior (p<.05). Compare asymmetry ratio of serratus anterior and lower trapezius muscle thickness showed a significant difference (p<.001). ICC for intra-reliability was .944~.962 in serratus anterior and .873~.925 in lower trapezius muscle thickness, respectively. SEM was .001~.004 in serratus anterior and .002~.008 in lower trapezius muscle. CONCLUSION: This study, using RUSI, showed significant difference in muscle thickness of serratus anterior in affected and unaffected side of stroke patients. RUSI is a practical tool for measuring soft-tissue thickness in the scapular region muscle of stroke.

PURPOSE: The purpose of this study was to find out variations in body posture by using the baby carrier at the front side and back side. METHODS: Thirty two healthy and young female who will bring up infants and had no musculoskeletal disorders of neck, lumbar and low limb were recruited for this study. They were each marked about ears of tragus, cervical 7th, acromion anterior end, anterior superior iliac spine, posterior superior iliac spine, greater trochanter and lateral malleolus as landmarks to measure variations of body posture when they carry infants at the front side and back side. Landmarks were regarded as the creteria in order to measure NeckFlexion angle(NF), Foreward shoulder angle(FSA), Pelvic tilt(PT), Sway angle(SA), Head displacement(HD) and Scapular displacement(SD). Variations in body posture were measured from the neutral position to the front and back side by using Image J. RESULTS: There were significance level (p<.05) in NF, PT, SA, HD and SD except for FSA in two different side. CONCLUSION: The results of this study indicate that each of the using ways of baby carrier for baby care was influenced postural responses of young women. therefore, it could be considered to apply to women who have abnormal body posture in order to minimize musculoskeletal disorders.

A clinical analysis was performed on 97 cases of chest injuries experienced at Department of Thoracic and cardiovascular Surgery, Armed Forces Capital Hospital during 2 years period from 1986 to 1988. Of 97 patients of chest trauma, 39 cases were result from penetrating injuries whereas 58 cases were from non-penetrating injuries, and there were 77 cases of hemothorax and / or pneumothorax, 47 of rib fracture, 8 of foreign body, 6 scapular and clavicle fracture, 5 of diaphragmatic injuries, 4 of paraplegia. The majority of chest injuries were encounted in the age group between 21 and 30 years-old, mean age was 25.9 years-old and all cases were male except one. Gun-shot wound was the most common cause in the penetrating injuries and the majority of non-penetrating chest injury patients were traffic accident and fist or kick accounted for next. The principles of therapy for chest trauma were rapid expansion of the lung by closed thoracostomy[45 cases] and thoracentesis only[3 cases] but thoracotomy done at 27 cases because of massive bleeding or intrapleural hematoma, foreign body, cardiac injury, diaphragmatic injury and bronchial rupture. The over-all mortality was 2.07 percent[2 cases among all], a case was from penetrating injuries and another was from non-penetrating injuries.

Purpose : To evaluate the efficacy of free musculocutaneous flap in the treatment of chronic osteomyelitis with drain sinus. Materials and Methods : Eighteen patients (sixteen male and two female) whose average age was 42.6 years were followed for an average of 3.5 years after free musculocutaneous flap for chronic osteomyelitis with drain sinus tract. The period of time between the initial injury and this procedure was average 10.6 years. The patients had an average of 4.1 prior surgical procedure before it. Results : Sixteen(88.9%) of the eighteen free musculocutaneous flap survived, including thirteen of latisimus dorsi flap, three of scapular free flap with muscle, two of medial plantar flap with abductor muscle. Sixteen cases had no evidence of recurrence at follow up. Conclusion : Free musculocutaneous flap is an extremely successful and reliable procedure for the treatment of chronic osteomyelitis with drain sinus. This flap with microvascular anastomses is highly vascularized through its own intrinsic blood vessels, which has the advantage of obliterating dead space and providing improved vascularity to the relatively ischemic recipient site and covering the skin defect.

Painful and disabling snapping scapula is an unusual condition and there have been several reports that have revealed good results after surgical treatment for unilateral snapping scapula. We experienced a case of bilateral painful snapping scapula in a young man, but with successful treatment by partial resection of the superomedial angle of both scapula. Preoperative 3-dimensional CT revealed bony prominence of the superomedial angle of both scapula and narrowing between superior scapular angle and chest wall.

From the viewpoint of clothing construction, it is necessary to grasp exactly the shapes of the neck and the shouder, such as the line of the neck base, the neck gradient, the shoulder gradient, the shape of the scapular, and the shape of the breast. In this report, factor analysis was applied to 39 items of neck & shoulder level measurements, including stature, weight, but grith, waist girth, to demonstrate the most relevant measurements for collar and bodice pattern designing, and to classify the neck and shoulder level shapes. The subjects investigated were 126 women of the age 20-29. The main results are follows : 1. For factors of body form were extracted by the factor analysis. The 1st principal component can be interpreted as "size" component, the 2nd-3th principal component is "shape" component relating to neck and shoulder level, and the 4th principal component is "shoulder shape" component. 2. With regard to factor loadings, we were able to extract the most relevant measurements for collar and bodice pattern designing. M16, M22, S26, S30, S34, S35, S36, C37, C38, C39.

Function and strength of the deltoid muscle are important in reverse shoulder arthroplasty (RSA). Moreover, location and shape of the acromion, clavicle, and scapular spine, which are origins of the deltoid muscle, are also important. The frequency of os acromiale is 5% to 15%; however, it is rare in the Asian population, affecting approximately 0.7% of Koreans. RSA has rarely been reported in patients with os acromiale. We present a case series of two patients with cuff tear and arthropathy combined with os acromiale who underwent RSA. From 2016 to 2018, two patients with os acromiale who presented with pain and limited range of motion (ROM) underwent RSA with cuff tear arthropathy using the subscapularis-sparing deltopectoral approach. Their ROM, visual analog scale (VAS), and satisfaction were evaluated before and after surgery. In both patients, VAS decreased, ROM increased, and postoperative satisfaction increased. There were no specific complications due to os acromiale. The VAS, ROM, and satisfaction of patients improved after surgery compared with values before surgery. However, careful attention must be given during surgery to ensure optimal repair and recovery.

Purpose : The purposes of this study were to test the effect of proprioceptive and vestibular sensory input on expression of BDNF after traumatic brain injury in the rat. Subject : The control group was sacrificed at 24 hours after traumatic brain injury. The experimental group I was housed in standard cage for 7 days. The experimental group II was housed in standard cage after intervention to proprioceptive and vestibular sensory(balance training) for 7 days. Method : Traumatic brain injury was induced by weight drop model and after operation they were housed in individual standard cages for 24 hours. After 7th day, rats were sacrificed and cryostat coronal sections were processed individual1y in goat polyclonal anti-BDNF antibody. The morphologic characteristics and the BDNF expression were investigated in injured hemisphere section and contralateral brain section from immunohistochemistry using light microscope. Result : The results of this experiment were as follows: 1. In control group, cell bodies in lateral nucleus of cerebellum, superior vestibular nucleus, purkinje cell layer of cerebellum and pontine nucleus changed morphologically. 2. The expression of BDNF in contralateral hemisphere of group II were revealed. 3. On 7th day after operation, immunohistochemical response of BDNF in lateral nucleus, superior vestibular nucleus, purkinje cell layer and pontine nucleus appeared in group II. Conclusion : The present results revealed that intervention to proprioceptive and vestibular sensory input is enhance expression of BDNF and it is useful in neuronal reorganization improvement after traumatic brain injury.

This study was performed to investigate the effect of ultrasound irradiation on epidermal growth factor(EGF) expression in rat wound tissue. Skin wounds were created below 5mm to both sides of scapular inferior angle. The right wound was used experimental side and left was used control side. Ultrasound was irradiated pulse rate $20\%$, frequency 1MHz, intensity $0.5W/cm^2$ for 5 minutes during 3days. After sonication during 3 days, rats were sacrified. The expression of epidermal growth factor evaluated immunohistochemistry on mouse anti-EGF. In the control side, a little expression of EGF was observed at epidermis and dermis. In the experimental side, A strong immunostaining was seen at epidermis and dermis. This study suggests that ultrasound irradiation is effective on EGF expression in wound tissue.
