The medial collateral ligament is the most commonly injured ligamentous structure of the knee. The management of the medial collateral ligament injuries were divided into surgical and conservative treatment. More recently, many investigators reported that isolated medial collateral ligament injuries did well under non-operative treatment. So, arthroscopic examination of the knee to rule out other intraarticular pathologic conditions such as cruciate ligament injuries, meniscal tear and osteochondral lesion is essential. From October 1993 to April 1995, we treated 45 cases of Grade III medial collateral ligament injuries and arthroscopic finding for cruciate ligament, meniscus, bony structure were analized in these cases. The result were as follows; 1. Anterior cruciate ligament injury:37.5% in +1 degree, 42.8% in +2 degree, 86.7% in +3 degree 2. Posterior cruciate ligament injury:12.5% in +1 degree, 13.4% in +2 degree, 33.3% in +3 degree 3. Meniscal injury:12.5% in +1 degree, 21.3% in +2 degree, 33.4% in +3 degree 4. Medial capsular ligament injury was more frequent and severe in the meniscofemoral ligament than in the meniscotibial ligament, but that finding was not correlated with degree of medial instability.

Platelet-derived growth factor(PDGF) is known to accelerate soft tissue fracture and periodontal bone healing, but little information is available for characterizing the healing of articualr cartilage. This study was designed to demonstrate the regeneration potential of pasteurized autogeneous osteochondral graft when PDFG was applied locally in vivo. Eighteen rabbits in two groups were used in the experiment. The free osteochondral fragment(1x1x1 cm) were taken from distal femur. The fragment were pasteurized in 65degrees C for 5 minutes. In experimental group(group II), the fragment were soaked in 0.25 mg/ml of recombinant human PDGF mixed 5 ml normal saline and reimplanted to the resected site, and followed with local administration of 0.25 mg/ml PDGF to knee joint. In control group(group I), the pasteurized fragment were reimplanted in the resected site without any treatments. The histologic characteristics of the transplanted autografts for three rabbits in each group were observed at 3, 5 and 7 weeks postoperatively. The results were as follows; Group II revealed the more favorable regeneration of articular cartilage, less arthritic changes and more mature arrangement of chondrocytes than group I. Even thought the cartilage is avascular and the regeneration capacity of pasteurized cartilage is severely limited, the regeneration of grafted articular cartilage is thought to be accellerated by increased newly formed blood vessels and soft tissues due to the diffusion of PDGF on grafted cartilage, and probably also by differentiation of mesenchymal cells in the initial stage of experiment. The results of this study suggest that local administration of PDGF could be used for the treatment of posttraumatic or degenerative arthritis and various cartilage damages.

Clostridium perfringens is an anaerobe responsible for a wide range of diseases in animals and humans. Symptoms associated with C. perfringens food poisoning are caused by enterotoxin expressed only during sporulation of C. perfringens. It has been known that only 6% of global C. perfringens isolates carry the enterotoxin gene. We found 2 strains of enterotoxigenic C. perfringens out of 33 strains isolated from various sources in Korea using PCR. It was also found that these two strains were both type A that were strongly associated with food poisoning by checking the presence of four major lethal toxins (a-, B-, e-, l-toxin) using PCR. These results suggest that foodborne illness caused by C. perfringens may be common in Korea and that public education is necessary to prevent contamination of foods by this organism.

BACKGROUND/OBJECTIVES: Eating-out among Korean people has become an important part of modern lifestyle due to tremendous growth of the food service industry and various social and economic changes. This study examined trends in meal patterns and meal sources while eating-out among Korean adults aged 19 years and older. SUBJECTS/METHODS: Data were from the 1998-2012 KNHNES (Korea National Health and Nutrition Examination Survey) by the 24-hour dietary recall method. This study included 55,718 adults aged 19 years and older. For analysis of eating-out frequency, data were categorized by source of meals and serving place. RESULTS: Average frequency of meals consumed away from home increased from 1998 to 2012, although it remained lower than that of meals at home. In addition, male, unmarried, employed, higher educated, and high income individuals more frequently consumed meals away from home. Moreover, sodium intake while eating-out significantly increased from 2,370 mg in 1998 to 2,935 mg in 2012. Lastly, percentage contributions of daily total protein intake, fat intake, and sodium intake from eating-out increased to more than half (53-55%) in 2012 compared with 47-48% in 1998. CONCLUSIONS: As eating-out has grown in popularity, greater recognition of public health and nutritional education aimed at promoting healthy food choices is needed. In addition to developing consumer education for overall healthier eating patterns, individuals who are younger, unmarried, higher educated, and males are especially at risk and require attention.

BACKGROUND: It has been well known that absolute and interpeak latencies of brainstem auditory evoked potentials (BAEP) are usually prolonged in diabetics. However, Its etiology is still controversial. We tried to identify whether the cause is structural or metabolic in origin by performing BAEP and brain MRI in the diabetic patients. METHODS: BAEP were performed in both the diabetic patients (DM) group (16 males and 15 females) and the normal control group (25 males and 33 female). A brain MRI was performed in the DM group on those who showed abnormal BAEP and com-pared the results of BAEP of the DM group with those of the control group. RESULTS: 7 patients (22.6%) showed abnor-mal BAEP (male; 6, female; 1, unilateral; 4, bilateral; 3) when abnormal BAEP was defined as being larger than two and a half standard deviations of the control group BAEP results. Two males of the DM group who showed abnormal structural lesions of the pons in their brain MRI were not included in the statistical analysis. The remaining 14 diabetic male patients (mean age: 58.7 +/-9.1 years, mean disease duration: 6.1 +/-4.7 years, mean hemoglobin (Hb) A1C: 7.7 +/- 2.0%) and 15 diabetic female patients (mean age: 60.6 +/-10.8 years, mean disease duration: 5.4 +/-5.1 years, mean HgA1C: 7.8 +/-2.1%) were stastistically analyzed. Interpeak latencies of I-III, III-V, and I-V were found to be signifi-cantly prolonged in the DM group. The prolongation of interpeak latencies of I-III and I-V were found to be signifi-cantly correlated with the disease duration only in the diabetic female patients, but not with age and HbA1c. CONCLUSIONS: These findings suggest that both metabolic derangement and structural lesion contribute to prolonging the central conduction time on BAEP pathway in diabetics.
