The posterior cruciate ligament(PCL) is one of the most important structures in the knee joing because it provides about 94% of the total restraint to posterior displacement of the tibia & posterior stability of the knee joint. If the posterior instability persisted, rotational instability, injury to meniscus and degenerative change develop within several years. The purpose of this study is to know the result of the posterior cruciate ligament reconstruction using semitendinosus tendon and to know the factors which affected to good result. During the period from January 1989 to December 1994, 16 cases with posterior cruciate ligament reconstruction using semitendinosus tendon were evaluated clinical and radiological results retrospectively and performed stastical analysis using the SPSS. The results were as follows; 1. The average preoperative posterior laxity was 14.1 mm and average postoperative laxity was 6.3 mm. It was improved 7.8 mm. 2. In other associated injured ligament group with or without fracture, above good was in 8 cases and below fair in 6 cases, but there was no significant difference between the two (X²=9.8, df=1, P>0.05). 3. In the poor result group, mean body weight was 80(±13.23)kg and there was significant difference between poor group & fair, good, excellent group(F=3.52, P < 0.05). From these results it would be suggested that PCL reconstruction using semitendinosus tendon is more effective in relatively light weighted group than heavier group.

The bone mineral density(BMD) of the lumbar spine (L2L4) was measured by using dual energy x-ray absorptiometry(Norland M6 DEXA) in 80 children aged between 2months and 15years (group I:2monthlyears, group 2: 1year5years, group3:6years10years, group4*: 11years15years). The correlation coefficient of BMD with age, body weight, height and Tanner stage were 0.696, 0.693, 0.717 and 0.636 respectively. There were sigificant difference. in BMD(g/cm2) between-group 1(BMD : 0.335 0.175) and group 2(BMD : 0.627 0.200), and group 3(BMD : 0.714 0.189) and group.4(BMD : 0. 8730.163) (P<0.05). There was no significant difference of BMD between boys and girls(P<0.05). BMD also increased significantly with development of Tanner stages(Tanner stage 1 : 0.547 0.234, Tanner stage 2 : 0.783 0.136, Tanner stage 3 : 0.998 0.080) (P<0.05). These data indicate that the BMD was correlated with age, body weight, height and Tanner stage significantly and BMD increased significantly during growth spurt occured in 1 to 4years of age and puberty.

Magnetic resonance (MR) is rapidly emerging technique that provides high quality images and potentially provides much more diagnostic information than do conventional imaging modalities. MRI is conceptually quite different from currently used imaging methods. The complex nature of MRI allows a great deal of flexibility in image production and available information, and key points are as follows. 1. MR offers a non-invasive technique with which to generate in vivo human images without ionizing radiation and with no known adverse biological effects. 2. Imaging mechanism of MRI is quite different from conventional imaging modality and for more accurate diagnostic application, It is necessary for physician to understand imaging mechanism of MRI 3. M.R. makes available basic chemical parameters that may provide to be useful for diagnostic medical imaging and more specific pathophysiologic information which are not available by alternate techniques. 4. M.R. can be produced by number of different methods. This flexibility allows the imaging technique to be applicated for particular clinical purpose. Multiplanar and three dimensional imaging may extend the imaging process beyond the single section available with current CT. 5. Future directions include efforts to; a. Further development of hard ware b. More fastening scan time c. Respiratory and cardiac gated imaging d. Imaging of additional nuclei except hydrogen. e. Further development of contrast media f. MR in vivo spectroscopy g. Real time MR imaging

Epidermolysis bullosa aimplex is a dominantly inherited syndrome characterized by the dissolution of the basal epidermal cells with mechanical stress. A 23 year-old man developed recurrent bullous eruptions with pain on hands, feet and face since childhood, which healed spontaneously without scarring. Grandmother of his father's side, father, aunt of his father's side and two of his three brothers had suffered similar skin lesions. Light and electron microscopy showed degeneration and bulla formation in the basal cell layer of epidermis and intact basement membrane attached to dermis.

We have experienced a case of infantile nephritic syndrome confirmed by renal biopsy in a 13-month-old female patient who showed and develop mental retardation and persistent proteinuria. She revealed mild eyelid edema, joint laxity, delayed speech development and adrenal cortical calcification on the radiologic study. Renal biopsy showed microcystic tubular change, micro-glomeruli and marked mesangial proliferation.

There have been no standard treatments for recurrent aphthous stomatitis, and clinical management is usually directed toward symptomatic relief. Recent immunological investigations have focused on possible imrnunopathogenesis of the disease. Several reparters suggested that levamisole, nonspecific immune-stimulator, had a beneficiaI effect in controlling attacks of recurrent a,phthous stomatitis and in reducing subsequent episodes. The present study was undertaken to evaluate the therapeutic effectiveness of levamisole in patients with recurrent aphthous stomatitis. A total of 8 patients who had had recurrent aphthous stomatitis for 2 to 20 years and who had experienced at least one episode per month were selected for this study from the department of dermatology, National Medical Center, through March 1979 to September 1979, Levamisole (Decaris') was given 150mg, p.o., once daily on 3 consecutive days every week for 2 months. Tbe results were as follows. 1) One patient had to have levamisole discontinued due to a high fever and exacerbations of tbe oral ulcerations. 2) 5 patients showed beneficial effects in reducing tbe number, frequency, pain and severity of recurrent aphthous stomatitis. 3') One patient showed no therapeutic response. 4) One patient, who has experienced new oral ulcerations continuously before starting levamisole, showed no recurrences of the lesions during the follow-up period of 3 months. 5) Side effects during levamisole administration were transient and generally mild, They included nausea, headache, dizziness and high fever.

To evaluate the effect of a new topical anesthetic cream (EMLA : Eutectic mixture of local anesthetics) on reducing pain associated with DPT vaccination, we conducted a clinical observation on eighty infants who were brought to well baby clinic of Yeungnam University Hospital for DPT vaccination. 80 Infants, who were between 2 months and 8 months in age, were divided into two groups. EMLA treated group and control group. Male to femle sex ratio was 1.4 to 1. EMLA cream was applied 60 minutes before DPT vaccination, the effect of reducing pain was assessed by using McGrath's face scale, Oucher pain scale and modified behavioral pain scale (MBPS) and also evaluated by measuring the duration and time of crying (the time of the first crying after iniection, duration of the first crying, total duration of crying). The scores of those scales were lower in EMLA treated group than in control group significantly (P<0.01 in McGrath's face scale. MBPS and p<0.05 in Oucher pain scale). There was no difference in the time of the first crying after vaccination in both groups. The duration of the first crying was shorter in EMLA treated group than control group of crying was also shorter in EMLA treated group (EMLA treated group 9.0±12.5 sec, p<0.05). Transient skin erythema was noted in 5 infants after EMLA application, but no other adverse effects were observed. We conclude that the application of EMLA cream before vaccination seems to be an effective and safe way to reduce the pain from vaccination, but it takes usually 60 minutes to get the anesthetic effect of EMLA and it is expensive, so EMLA cream can not be recommended in routine vaccination in infants now.
