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.

Authors examined the morphology and size in the maxillary lateral insicor from Korean adults and the following conclusion have been drawn. 1. In the shapes of labial surface in maxillary lateral incisors, the quite prominent middle lobe, moderate prominent middle lobe, less prominent midd1e lobe were 20.60%, 69.85%, 9.55%, respectively. 2. In the shapes of incisal margin in maxillary lateral incisors, the arc shaped to the distal, round, nearly straight were 24.96%, 60.20%, 15.11%, respectively. 3. In the shapes of incisal angle in maxillary lateral incisors, the equal sized mesioincisal angle and distoincisal angle, larger distoincisal angle, much larger distoincisal angle were 8.36%. 67.34%, 24.30%, respectively. 4. In the shapes of lingual surface in maxillary lateral incisors, the marked shovel (Ms), semi-shovel (Ss), trace shovel (Ts), no shovel (No) were 43.00%, 33.50%, 19.50%, 4.00%, respectively. 5. The size of the maxillary lateral incisors were as follows. 6. In comparison with Wheeler's data, crown length, crown width and crown thickness were larger in Korean adult, but the degree of cervical curvature were smallest.

As an attempt to evaluate any possible effects of dimethylsulfoxide (DMSO) on the phenomena of membrane transport, effects on the short-circuit current (SCC) and potential difference (PD) across the isolated frog skin were studied under the conditions of various bathing medium, Changes of SCC and PD were measured by the method described by Ussing and Zerahn. Addition of DMSO to the inside bathing medium resulted in an initial increase in SCC followed by a secondary decline to pre-DMSO level, while DMSO at outside medium was without effect. Dose-responses(SCC) relationship revealed a linear one from 30 to 60 mM. Substitution of chloride by sulfate ion from bathing medium caused no alteration in the basic pattern and magnitude of response, thus indicating the specificity of DMSO action on the Na transport. Hypertonic solutions of DMSO added to either outer or inner bathing medium evoked a prompt fall in SCC and PD consistently. By isotopic measurement of sodium fluxes with Na24, it was evident that increased sodium influx was entirely responsible for the initial increase in SCC induced by DMSO. Of various parameters concerned with transepithelial Na transport, outer membrane permeability to Na (PoNa) was shown to be the onIy parameter which was significantly elevated by DMSO administration. From these findings, it was postulated that DMSO-induced increment in sodium influx was mediated by its stimulating action on the sodium penctration through the outer permeability barricr after binding to a receptor site different from that for the antidiuretic hormone (ADH.)
