The meniscus has improtant functions of shock absorption, load transmission, lubrication and significant contribution to stability of the knee. Accordingly, repair rather than excision can be expectd to be satisfactory and functional teatment for knee joint. We had Repaired 56 cases of meniscal tears from March, 1987 to September of 1992, among which 42 cases were followed up for at least 12 months to 60 months at most(in average 36 months). The results were as follows; 1) In medial meniscal tears, 26 cases were acute, while five were chronic. As for the lateral meniscus, acute and chronic teats were observed in nine and two cases, respectively. 2) Eleven of the 35 acute tears were associated with anterior cruciate ligament tears, while three of seven chronic tears were associated with anterior cruciate ligament tears. 3) Second-look arthroscopic examinations were performed on nine repaired cases. Retears occurred in two cases and seven cases revealed healing at repair sites. 4) Two cases(5%) out of 42 repaired menisci were return during follow-up. One was a case of isolated meniscal tear and the other was associated with rupture of anterior cruciate ligament. 5) Two return cases were repaired in the chronic stage of more than one year after trauma. 6) The standing radiographs which were taken in full extension and 45 flexion on eight out of 13 patients, who had been followed up for more than 4 years showed intact joint space without narrowing.

Metaphyseal Chondrodysplasia is a disease characterized by metaphyseal ossification leading to shortening of stature. The extremities, especially lower, and mainly affected, resulting in a disproportionate drarfing which spares the trunk. The first case was reported in a patient with irregular metaphysis of lower extremities and hands, and severe shorteness of stature by Murk Jansen in 1934. A milder form of Metaphyseal Chondrodysplasia was noted in 1949 by Schmid, which is more common and transmitted in autosomal dominant. Mckusick recently reported another form of Metaphseal Chondrodysplasia, and other types were reported, but they are extremly rare, and of little clinical significance. In the Schmid type, patient is normal at birth, but characteristically shortness of stature, bowed leg, and waddling gait developed at biginning of walking. Ali labratory findings including serum calcium level, phosphorous, alkaline phosphatase, renal function test is normal in Metaphyseal Chondrodysplasia. The most difficult differential diagnosis is Vitamin D-resistant rickets in clinical and x-ray findings. The only treatment is careful observation and properly timed corrective surgery. Authors experienced on case of Schmid type of Metaphyseal Chondrodysplasia which had been treated with Vitamin D under impression of rickets for 1 year before the case was consulted to Orthopedic Department. Proximal tibial osteotomy and subtrochanteric valgus osteotomy were performed for the correction of genu varum and coxa vara deformity with satisfactory results for one year follow up.

BACKGROUND: There is much harmful influence for health promotion when general publics and medical group misunderstand common health knowledge. Therefore we investigated the proportion of misunderstanding about health knowledge of general publics and medical group. METHODS: The data were collected via questionnaire which consisted of 30 questions (ll health behavior, 5 symptom, 14 treatment knowledge) quoted or revised on the basis of the book ('Misunderstood common health knowledge 100' published by humanism practice medical doctor association, 1994, hanwol company, South korea). The subjects were nonmedical group (third grade elementary school teachers and parents of students in Kyong ju city) and medical group (doctors-specialist, resident, intern, oriental doctor, medical student, nurse, assistant nurse in Kyong-Ju, Pohang city). The score was given 0 for false answer or no answer and 1 for true answer. RESULTS: The dominant subclasses of study subjects were as follows .Sex; female(352:64.5%)/age; 30-40 years old(318 persons : 58.5%) education ; high school graduate group(232: 42.8%)/job; nonmedical group(housewives, 168:36.2%), rnedical group(nurse, 67:36.2%). Medical group acquired higher total average score than non-medical group. There were no differences in the total scores about treatment, symptom, and health behavior in nonmedical group by job. In the medical group, doctors earned significantly higher score than other jobs. The average score per question was 0.53 in nonmedical group and 0.69 in medical group. Non-medical group received average score below 0.5 in 14 questions among 30 questions, while medical group received only in 5 items. CONCLUSIONS: Medical group acquired higher total average score than nonmedical group. Average score per question was 0.53 in non-medical group and 0.69 in medical group.

This study was to investigate the various parts of the mandible related to inferior alveolar nerve conductive anesthesia in 228 dry skulls of Korean adults. Five morphological variations were observed and four measurements were undertaken. The following results were obtained. 1. The Position of coronoid notch in the anterior border of the ramus of mandible is classified into three types and percentage of each type was as follows : Type I (Coronoid notch in the middle part of the anterior border of the ramus of mandible) : 83.3% Type II (Coronoid notch in the inferior part of the anterior border of the ramus of mandible) : 12.7% Type III (No coronoid notch in the anterior border of the ramps of mandible) : 4.0% 2. The position of the lingula of mandible to the imaginary line of the molar occlusal plane is classified into three types and percentage of each type was as follows : Type I (Above the imaginary line of the mandibular molar occlusal plane) : 87.3% Type II (Coincide with the imaginary line of the mandibular molar occlusal plane) : 8.6% Type III (Below the imaginary of mandibular molar occlusal plane) : 4.3% 3.

A number of chronic inflammatory lesions of unknown etiology in man have recentlybeen understood by the mechanism of so called auto-immune disease and a series of experimental study using animals have been extensively undertaken to reproduce the lesion. Experimental chronic inflammatory diseases induced by repeated injection of homologous or heterologous tissue antigen with adjuvant are based upon immunological process and these are readily reproducible. The author has experimentally studied on any allergic destruction of the epididymis of the rat on immunologic process as in other particular organs and tissue. A total of 59 white healthy male rats were divided into 7 major experimental groups of injection as follows. Group 1: six rats, control, injection with normal saline alone. Group 2: six rats, injection with adjuvant only. Group 3: six rats. injection with epididymal tissue only. Group 4: twenty-three rate, injection with rat epididymal tissue plus adjuvant. A. seven rats, sacrificed on the 64th day B. ten rate, sacrificed on the 92nd day C. six rats, sacrificed on the 128thday Group 5. six rate, injection with rat epididymal tissue plus adjuvant plus prednisolone. Group 6: six rats, injection with rabbit epididymal tissue only Group 7: six rats, injection with rabbit epididymal tissue plus adjuvant Injections were given into the abdominal muscle of the rat once s week for 8 weeks as scheduled in the text and the animals of all groups except the group 4, were sacrificed 8 days after the final injection. In the group 4, animals were further divided into 3 subgroups which were sacrificed on the 61st, 92nd and l28th day of the experiment, respectively. The epididymis and other organs of allexperimental animals were studied histopathologically and the following results were obtained; 1. In all rats of the group 1 receiving homologous epididymal tissue with adjuvant, the epididymis revealed relatively marked and significant inflammatory changes. Histopathology included edema, congestion, fibrosis in the interstitial tissue, and infiltration of inflammatory cells mainly composed of lymphocytes, histiocytes, plasma cells and eosinophils. Flattening and hyperplasia of the epithelial cells and cellular exsudation were observed in the tubules. 2. In the group 1, the lapse of time after injection provoked more marked inflammatory changes. Diffusely mild or moderate degree of inflammation observed on 61st day, was changed to diffusely moderate or marked inflammation on 92nd day and then to significantly more chronic lesion with less exsudation and more fibrosis on 128th day. 3. Homologous tissue antigen without adjuvant andheterologous tissue antigen with or without adjuvant caused no inflammatory changes. 4. Inflammatory changes induced by homologous tissue antigen with adjuvant seem to be readily inhibited or prevented by simultaneous administration of prednisolone.
