Since Duhamel (1739), numerous experimental studies on the longitudinal growth of growing long bone have been reported. In Hales(1747) experience, growing long bone showed overgrowth after drilling in the tibia of chickens. David(1924) observed the fact that various degrees of shortening disappeared within 15 months after fracture of the femur in children and he concluded that fractures in children should be treated with the caution that the growing long bone has a tendency to increase in length after injury. Bisgard(1936) concluded that shortening from overriding of fragments in fractured extremities of children will frequently, but not invariablly, become partially or totally eliminated by the acceleration of growth which incidentaIly results from the inflammatory process, incited by trauma and fracture repair. Hass(1926) reported that interstitial proliferation of osseous tissue plays no part in the elongation of a growing bone, either in the mature bone or the young osteoid tissue bordering on the epiphyseal cartilage plate, and length growth of bone is entirely dependant on the purposeful multiplication of cartilage cells of the epiphyseal cartilage plate. Ham(1952) reported that the growth of long bone depends upon the interstitial growth of cartilage. This study was initiated to investigate the effects of fractures in the longitudinal bone growth of growing bone. Artificial fractures were made at two different sites in the diaphysis of the tibia in young rabbits. The operation for artificial fracture was performed under general anesthesia with ether. The type of fracture was an incomplete one, leaving a part of the posterior cortex of the tibia, in order to prevent the displacement of fractured fragments. In all of the cases, no cast immobilization was applied. After the fractures, follow up observations were made weekly till the 4th week, and thereafter at two week intervals, with roentgenographic, lethal measurement and histological examination. The results were as follows; 1) Longitudinal bone growth was increased from fracture of the diaphysis of growing long bone. 2) Compared with the control limb, tendency to overgrowth of growing bone was noted from the first week after the operation. 3) In follow up measurements, no growth inhibition was observed till the 10th week after the operation, but, thereafter, a tendency to reduce the proliferation of cartilage cells was noted. 4) In cases of fracture of the mid 1/3, the gorwing activity in the epiphyseal plate was increased more than from proximal 1/3 fractures. 5) The bony growth, accelerated by fractures in diaphysis of growing long bone without displacement was transient, and the prolonged overgrowth was compensated by the reduction of growing activity and premature closure of the epiphysis.

An appreciation of the range of normal variation and normal values for the pelvis and hip remains a continuing problem for the orthopedic surgeon in Korea. To help overcome this problem and to provide a comprehensive single source for this information, I have undertaken a study of 1037 unselected Korean subjects (605 normal males and 432 females) who varied in age from newborn to 86 years. The present study is concerned with normal angles and distances of the pelvis and hip, examined roentgenographically for statistical survey from January 1965 to August 1971 at Severance Hospital in Korea. The results of this study are as follows: 1. The value of the C-E angle, distance h, and distance d is increased according to increment of age but the value of the femoral neck shaft angle, acetabular angle, iliac index and interval of symphysis pubis is decreased with age. 2. The acetabular index in all age groups, iliac angle in the 1–3 months group, C-E angle in the 6–10 months group and the adult group over 18, interval of the symphysis pubis in the 4–22 year group, distance h in the 3–6 months group and the 4–8 year group, and distance d in the 1–3 months group show a difference between males and females. 3. There are differences between normal females and pregnant women in the interval of the symphysis pubis. Also the degree of relaxation of joints of the pelvis is higher in primigravida than multigravida. 4. The value for the femoral neck shaft angle is higher in Koreans than Europeans.

This study was conducted to evaluate the effect of PTSD on memory funtion and hippocampal volume, and to identify major variables correlated to hippocampal volume and memory function. Thirty four Vietnam veterans were collected for this study, among whom eighteen were PTSD patients and sixteen were combat control subjects. The author used Impact of Event Scale(IES), Combat Exposure Scale(CES), Hamilton Depression Rating Scale(HDRS) and Beck Depression Inventory(BDI). Korea Memory Assessment Scale(K-MAS) was assessed for memory function. Magnetic resonance imaging(MRI) was used to measure hippocampal volume. There were significant differences between PTSD and Non-PTSD veterans in IES, HDRS and BDI. Significant difference was found in verbal memory and total memory of K-MAS between PTSD and Non-PTSD veterans. There was significant difference in hippocampal volume between PTSD and Non-PTSD veterans. Short term memory, verbal memory and total memory were positively correlated to hippocampal volume. Hippocampal volume was negatively correlated to IES, HDRS, and BDI. These results suggest that PTSD severity be associated with hippocampal atrophy and memory dysfunction. Reduced or smaller hippocampal volume may be preexisting risk factor for stress exposure or the development of PTSD on combat exposure.

Cross-sectional imaging plays an increasing role in the diagnosis of appendiceal diseases due to known highnegative appendectomy rate. It is important for radiologists to be aware of the computed tomographic (CT)appearances of various pathologies and common associated findings which can mimic other diagnostic entities. Inthis article, the author illustrates the CT appearances of a spectrum of appendiceal disaeses and outlinespotential diagnostic pitfalls.

Myositis ossificans progressiva is a rare disease characterized by the formation of areas of calcification in the interstitial connective tissue of muscles, tendons, ligaments, fascia, and aponeuroses. There may be exacerbations and remissions of the disease, but the general course is an insidious loss of body motion, affecting especially the neck, spine and upper extremities and, rarely, the hips and lower extremities. It is commonly associated with various congenital anomalies. The cause is unknown and there is no known effective treatment. Myositis ossificans progressiva associated with brachydactyly of both great toes, in a 34 year old femaIe, is presented with a review of the literature. Chief complaints were ankylosis of the left knee and hip of 9 years duration. We performed biopsy of tubular bone which is placed antero-lateral side of the left knee.

This case report describes a patient with semipedunclated granuylar cell tumor(granular cell myoblastoma) of the proximal ascending colon removed by endoscopic polypectomy. A 39-year old femalie was visited to our hospital for intermittent abdominal pain and loose stool. Colonoscopic examination showed a semipedunclated lesion covered with yellowish white smooth mucosa in the proximal ascending colon. The tumor was removed by endoscopic polypectomy. The collected specimen was 0.9x0.8 cm in size. The cut surface of the specimen showed a white round firm tumor covered with mormal epithelium of the colon. Using immunohistochemical study, the tumor cells were to be positively stained by S-100 protein and negatively stained by desmin, which supports the concept of the Schwann cell origin of granular cell tumor. In Korea, 2 cases of granular cell tumor of the colon and rectum, which were treated by surgical removal, have been reported. This case in the first endoscopic polypectomy of granular cell tumor of the colon and retum in Korea. The endoscopic polypectomy is thought to be useful for the therapy of small pedunclated or semipedunclated granular cell tumor, intracolonic type.

OBJECTIVES: The purpose of this study was to investigate the risk factors in veterans for posttraumatic stress disorder and to find the correlation between the disorder and the characteristics of the variables. METHODS: We compared the risk factors in veterans between 40 diagnosed PTSD patients and 78 controls, using psychiatric by psychiatrists and measurement instruments such as CES, Mississippi scale, and BDI RESULTS: 1) There was statistically significant difference in prevalence on pre-military factor with regard to age at recruit(p<0.05) 2) PTSD on military factor was closely correlated with CES score(p<0.05) 3) There was statistically significant difference in PTSD on post-military factor with regard to occupation(p<0.05) 4) Scores of Mississippi scale, and BDI in PTSD were higher than those in control subjects(p<0.05, p<0.05) CONCLUSION: This results suggest that the likehood of developing PTSD in veterans depends on pre-military and post-military factors in addition to features of the trauma itself. Age of entry into the military, CES score, and occupation had statistically significant relationships with PTSD.
