The posterior cruciate ligament plays as basic stabilizer of the knee. Therefore the knee becomes unstable when tibial insertion of the posterior cruciate ligament is avulsed. The diagnosis may be delsyed or missed because of surgeon's 1sck of awareness or rare condition. The authors treated seven cases of avulsion fracture of posterior cruciate ligsment at the tibial attachment ares ranged from ten to thirty-two years. There were five male and two female. The results were as follows : 1. The cause of all seven cases injury was traffic accident. 2. The physical findings were seven positive posterior drawer test, seven cases of abrasion or laceration over the anterior proximal tibial surface and antero-medial surfsce of the knee joint. 3. The associated injury was comminuted fracture of the tibia and femur (1 case), rupture of collateral ligsment and comminuted fracture of the tibia (1 case) and zygomatic fracture (1 case). 4. The treatment methods were four cancellous fixation, one K-wire fixation after epiphyseal plate fusion but each one pull out wire and dexon suture before epiphyseal plate fusion. 5. The motion of knee joint was within normal limit and no instsbility was inspected at the three months after reduction.

The aim of this study was to investigate the effect of hypoxia-reoxygenation on the proliferation of fibroblast, and to elucidate the role of oxygen free radicals in this process. Malme-3 fibroblast, derived from human skin fibroblast, was used for this study. The hypoxia or reoxygenation condition was made by exposing cultured cells to the environment of 95% N2, 5% CO2 or 95% room air, 5% CO2, respectively. Cell proliferation was estimated by the cell numbed, and DNA synthesis was measured by the [3H]-thymidine uptake. Release of oxygen free radicals was measured by the means of Ohkawa's method of lipid peroxidation. The effect of oxygen free radicals was confirmed by using dimethylthiourea(DMTU) and alpha-tocopherol, two known oxygen free radical scavengers. The results are as follows: 1. The dissolved oxygen of the culture medium was 8.97+/-1.23 ppm in the normal condition. When the culture dish was exposed to the hypoxic condition for 3 or 6 hours, the dissolved oxygen of the culture medium decreased markedly to the level of 3.10+/-0.46 ppm or 2.37+/-0.47 ppm, respectively 2. The number of cultured cells increased in a hypoxia duration-dependent manner up to 6 hours when the cells were cultured for 24 hours after hypoxia. The same pattern was observed in the cells cultured for 48 hours after hypoxia. Lipid peroxidation in the culture increased after the exposure to hypoxia-reoxygenation. DMTU or alpha-tocopherol blocked the increase in lipid peroxidation induced by the exposure to hypoxia-reoxygenation. 3. [3H]-thymidine uptake of the cultured cells increased after the exposure to hypoxia-reoxygenation. 4. DMTU or alpha-tocopherol blocked the proliferation of fibroblasts induced by the exposure to hypoxia-reoxygenation. The increase in lactate dehydrogenase (LDH) activity was also noted after the exposure to hypoxia-reoxygenation, and this increase was blocked by DMTU or alpha-tocopherol. These results indicate that the hypoxia-reoxygenation induces the proliferation of fibroblasts, and that oxygen free radicals play an important role in this process. Moreover, oxygen free radical scavengers may be of potential therapeutic value in preventing fibrosis.

STUDY DESIGN: A retrospective analysis was performed on 40 patients who had had previous lux bar spine surgeries. OBJECTIVE: To determine what factors most influenced surgical outcome and to analyze results in a series of revision lumbar surgeries. SUMMARY OF BACKGROUND DATA: Satisfactory surgical outcome of the revision lumbar surgery range from 28% to 82% and are rarely comparable to primary surgery. Many factors predicting outcome from repeat lumbar surgery haute been listed. METHODS: Forty patients were analyzed who had had previous lumbar surgeries. The patients were classified into 5 groups according to diagnosis: 3 Infection,5 instability,8 nonunion, 14 HNP and 10 spinal stenosis. of 40 patients,33 patients(82.5%) underwent fusion with instrumentation for repeat surgery. Their clinical course was followed for a minimum of 1 year. The number of surgery on each mpatient was 1.3 times on an average. RESULTS: Overall, 80% of patients had a satisfactory result. Obviously extruded or sequestrated HNP in MRI findings, complete block of contrast with severe radiculopathy and/or myelopathy in spinal stenosis, complete decompression, neurolysi s and fusion with instrumentation, and longer than 6 month pain relief after precious surgery were correlated with satisfactory outcome. However, the number of precious operation, age, repair of pseudarthrosis , no abnormality at surgery and combined multiple degenerative joint disease were significantly correlated with poor surgical outcome. The most common complication during repeat surgery was dural tear in 5 cases(12.5%). CONCLUSIONS: Success rate of revision surgery was low as compared to primary operation. Therefore, erroneous diagnosis and faulty surgical technique understandably lead to failure, and precise attention to preoperative and intraoperative detail can minimize these sources of error.

Characterizations of the VP4 (P type) and VP7 (G type) genes of Korean isolates of bovine rotavirus were performed using RT-PCR/RFLP and nucleotide sequencing analysis. After RT-PCR amplification of partial length (1094bp) of the VP4 and full length (1062bp) of the VP7 genes, amplified PCR products were digested with restriction endonucleases and digestion patterns were compared with those of reference rotaviruses. With the VP4 genes, four RFLP (AD) profiles were observed; three (A, B and C) were the same as those of bovine rotavirus NCDV (P[1]), IND (P[5]) and B223 (P[11]), respectively, Profile D was the same as that of porcine rotavirus OSU (p[7]). With the VP7 genes, five RFLP profiles (I-V) were observed; three of them (1, II and III) were the same as those of bovine rotavirus NCDV (G6), Cody I-801 (G8), and B223 (G10), respectively, Profile IV and V were atypical to those of reference bovine rotaviruses used in this study. These two profiles were identified as G6 and G5, respectively, after analyzing and comparing the nucleotide sequences. The G typing analysis revealed that 61.9% (26/42) were G6, which included G6 subtype; 28.6% (12/42) were G5; 7.1% (3/42) were G10; 2.4% (1/42) were G8. The P typing analysis revealed that 54.8% (23/42) were P(5); 28.6% (12/42) were P(7); 11.8% (5/42) were P(11); 4.8% (2/42) were P(1). Our results showed that G6/P(5) were the most prevalent rotaviruses in diarrheic calves in Korea. Also, this is the first report that G5P(7) rotaviruses were identified from cattle with diarrhea.

BACKGROUNDS: Korean Activities of Daily Living(K-ADL) scale was developed to measure the elderly function. The aim of the present study was to establish the validity and reliability of Korean Activities of Daily Living(K-ADL) scale. METHODS: Clinical validity and convergent validity was tested. Reliability was tested by internal consistency(Cronbach's alpha), two weeks test-retest method, and interrator correlation. RESULTS: Cronbach's alpha was 0.937. 2 weeks test-retest correlations in all 7 items were higher than 7.0. Interrator agreements were high in all 7 items(h=0.86~1.0). Nonnal control group had lower scores than patients group in all 7 items(p=0.000). Correlation coefficients between K-ADL score and braindisability grade was between -0.465(eating) and -0.696(bathing)(p=0.000). CONCLUSIONS: Korean Activities of Daily Living(K-ADL) scale is a valid and reliable instrument. In the future, the studies showing an association between K-ADL and mortality, prognosis are needed.
