1.Studies on lactic dehydrogenase activities in developmental stages of fertilized eggs of Ascaris lumbricoides.
The Korean Journal of Parasitology 1969;7(1):43-47
The lactic dehydrogenase activities of Ascaris lumbricoides have been assayed according to the developmental course of the fertilized eggs compared with the unfertilized eggs. Experimental procedures were modified that of Wroblewski and La Due's method with use of diphosphopyridine nucleotide reduced form(DPNH). Sodium pyruvate and lactic dehydrogenase, the specific activities were expressed as DPNH unit per mg protein by method of Kornberg's. The experimental results are as follaws: Lactic dehydrogenase activity in fertilized eggs of Ascaris are significantly increased from morula stage and its optimal pH is in 3.4 degrees. While any activities were not observed in unicell stage of fertilized eggs and unfertilized eggs. Water soluble protein of fertilized eggs of Ascaris were varied in their amount during their developmental process. The amont of protein in tadpole stage eggs have increased to 1.3 times more than that of cleavage stage eggs. However the amounts of water soluble protein in unfertilized eggs are revealed to one-third less than that of fertlized eggs. The specific activity of lactic dehydrogenase in tadpole stage eggs are decreased to one third less than those of morula stage eggs during development, the stage is considered to be as a growth criteria in developmental process, as on this point the activity of aerobic cytochrome c oxidase and cyclophorase begin to increase respectively.

7.A Case of Ketoconazole Treatment in McCune-Albright Syndrome.
Journal of Korean Society of Pediatric Endocrinology 1998;3(2):242-249
The McCune-Albright Syndrome is characterized by polyostotic fibrous dysplasia, cafe-au-lait colored patches of the skin and endocrinological abnormalities, including precocious puberty. Affected patients progress from GnRH-independent puberty to GnRH-dependent puberty. GnRH analogues are ineffective in GnRH-independent precocious puberty. Three year and 2 month old girl with breast development(SMR B3) and irregular vaginal bleeding were seen & diagnosed as incomplete sexual precocity. Decapeptyl treatment was started for the purpose of regression of breast development & vaginal bleeding with no effect. After 10 months, cafe-au-lait skin lesion & polyostotic fibrous dysplasia were noted and diagnosed as McCune-Albright syndrome. Breast development regressed to SMR B2 and vaginal bleeding was controlled with ketoconazole. As our experience, ketoconazole treatment might be effective to delay the progression of sexual development in patients with precocious puberty in McCune-Albright Syndrome.

8.The Effect of Fractures on the Longitudinal Bony Growth of a Growing Long Bone in Raddits
The Journal of the Korean Orthopaedic Association 1971;6(3):231-241
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.

9.Clinical Evaluation of Congenital Dislocation of the Hip
The Journal of the Korean Orthopaedic Association 1971;6(3):171-181
Congenital dislocation of the hip has always presented an unique problem in Orthopedic Surgery. Orthopedic surgeons have been baffled not only by the mystery of its origin, but also by its unpredictable course and the uncertainty of results of treatment. Hippocrates described this condition first with all its distinguishing characteristics, including distortion of the hip, the pathologic gait, the exaggerated lordosis. etc, His prognosis in this luxation of early childhood appeared to be unfavorable. In 1895, Lorenz established a new, decidedly conservative method of treatment. His process involved a complete separation of the two objectives to be fulfilled, namely reduction and retention. To retain this reduction he conceived the motion of fixing the hip for a specific and prolonged period in carefully chosen “primary position” of 90 flexion and 90 abduction by forcibly maintaining the head in its normal location. Ortolani, in 1935, was the first to show that a diagnosis could be establisted immediately after birth. The jerk, click or snap elicited by manipulation of the new born infants hip. Early diagnosis is still the most important aspect of congenital disiocation of the hip. Despite the emphasis on early diagnosis, a disturbingly large number of congenital dislocation of the hip remain undiagnosed until after the child has started to walk. Numerous surgical procedures and modifications have been used. The general types are: 1) Open reduction, 2) Shelf procedure, 3) Innominate osteotomy, 4) Arthroplasty, and 5) femoral osteotomy. These procedures have been useful also with the more difficult problem of residual or recurrent dislocation or subluxation aftertreatment by closed or open method. Congenital dislocation of the hip was not common in Korea like as in western countries. The reasons for this are poorly understood. But racial differences and native customs may offer a partial explanation. The author studied congenital dislocation of the hips in sex incidence, site of predilection, clinical symptoms and signs, X-ray findings, relation to the congenital anomalies and birth history, and the results of treatment. In this study, 57 cases of congenital dislocation of the hip, admitted to the orthopedic department of Severance Hospital during 7 years and 6 months since January 1963 until June 1970, were reviewed. The results of this study are as follows: 1. The annual changes of the numbers of the patients, who were first seen at Severance Hospital, were increasing. 2. The female incidence in Korea is relatively low as compared with the western countries. And the preponderance of females over males is in the ratio of ten to one in bilateral cases and two to one in unilateral cases. 3. The ratio of bilateral cases: right sides: left sides is 1:2: 2.2. 4. In these series, 15 cases of congenital anomalies or diseases in 13 patients are combined and among them, 10 patients are included in teratologic groups. And most common co-existing anomalies are club foot (7 cases). The incidence of the teratologic dislocation in Korea is relatively high as compared with the western countries. 5. The acetabualr index in affected hips showed no relationship to the age factor, but C-E angle, Y-coordinate and height are aggravated according to the increment of age. 6. Closed reduction is satisfactory under the age of 3, but after then the prognosis is poor. 7. Open reduction is recommendable after the age of 3 and under the age of 9. 8. The prognosis of treatment in bilateral cases and teratologic groups is poor.

10.A Study on the Roentgenographic Measurement of the Pelvis and Hip in Koreans
The Journal of the Korean Orthopaedic Association 1972;7(1):41-51
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.
