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.

Streptococcus anginosus is a member of Streptococcus milleri group, and is found in the oral mucosa, respiratory tract, and gastrointestinal tract as normal flora. It can develop into a disease in patients with deteriorating clinical condition or with clinical risk factors. A previously healthy 15-year-old boy was admitted due to fever, abdominal discomfort and vomiting which lasted for 7 days. He had a history of dental procedure 1 day before the development of fever. He was diagnosed with acute acalculous cholecystitis based on the clinical, laboratory, and imaging finding, and S. anginosus was isolated from the blood culture. The patient was successfully treated with antibiotic therapy.

OBJECTIVE: To estimate the burden of cardiovascular disease attributable to the total suspended particulates (TSP) and sulfur dioxide (SO2) in Korea using the YLD (years lived with disability) measurement. METHODS: Congestive heart failure(CHF) and myocardial infarction (MI) were chosen as the main cardiovascular diseases whose causes are attributable to the TSP and SO2 levels. In order to calculate the YLD (years lived with a disability), the following parameters in the formula were estimated. : the incidence rate, the case fatality rate, The expected duration of a disability and the average age of onset were estimated. The expected duration of a disability and the average age of onset were calculated using the DISMOD method, as developed by the GBD researchers. The burden of cardiovascular disease due to TSP and SO2 was estimated using the number of years that the patient lived with a disability. RESULTS: The YLD of the CHF due to the TSP and SO2 was attributed to the TSP (94.4 person-year) and SO2 levels (35.0 person-year). The YLD of the MI due to the TSP and SO2 was attributed to the TSP (148.4 person-year) and SO2 levels(27.6 person-year). CONCLUSION: The YLD method employed in this study was appropriate for quantifying the burden of cardiovascular disease. Therefore, it would provide a rational basis for planning a national health policy regarding the disease burden of the risk factors in Korea.

Seventy four consecutive cementless Tricon-M total knee replacement were followed for two to eight years (average three and half years) at the Department of Orthopedics Kangnam St. Mary's Hospital Catholic University Medical College. Using the Hospital for Sepcial Surgery rating system we found that 86.6 percent of the knee were graded excellent or good, 8 percent fair and 5.4 percent poor. In four cases of complication, two patients had gram negative infection postoperatively and one had one stage revision using gentamycine mixed cement and the other who had delayed infection one year after surgery had arthroscopic irrigation and synovectomy. Other two complications were patella lateral sublugation but the realignment operation had been refused. In radiologic examination there were no radiolucenct loosening sign in any patella or femoral component but tibial radiolucency was seen in only three patients. Thirty four (46%) out of 74, cases showed tibial component subsidency (average 2.2mm) during the first one year follow up period but no further progression was seen in later follow up period. No correlation.between radiolucency or subsidence and knee scores was seen. Cementless fixation of all components in total knee replacement, including the tibia and patella, was highly successful and can be achieved without stress relief of the distal femur.

We report a case of calcific bursitis of the shoulder in four-year-old boy who had severe pain and limitation of motion of the left shoulder joint for three days. Radiographs revealed the oval radiopaque lesion in the subacormial space, and the MR signal intensity of the mass was moderate on T2WI. Histological examination of the mass showed acute necrotizing inflammation with calcification.

Diallyl disulfide (DADS) induced apoptosis through the caspase-3 dependent pathway in leukemia cells was earlier reported from this laboratory. In this study, we investigated the involvement of Ca(2+) in DADS-induced apoptotic cell death of HCT-15, human colon cancer cell line. DADS induced the elevation of cytosolic Ca(2+) by biphasic pattern; rapid Ca(2+) peak at 3 min and following slow and sustained elevation till 3 h after the addition of DADS. Production of H(2)O(2) was also observed with its peak value at 4 h. Apoptotic pathways including the sequence of caspase-3 activation, poly(ADP-ribose) polymerase cleavage, and DNA fragmentation by DADS were completely blocked by various inhibitors such as specific caspase-3 inhibitor, free radical scavenger, and intracellular Ca(2+) chelator. N-acetylcystein and catalase treatment prevented the accumulation of H2O2 and later caspase-3 dependent apoptotic pathway. However, these radical scavengers did not block the elevation of intracellular Ca(2+). Treatment of cells with 1, 2-bis (2-aminophenoxyethane)-N, N, N-tetraacetic acid tetrakis -acetoxymethyl ester (BAPTA-AM), cellular Ca(2+) chelator, resulted in a complete blockage of the caspase-3 dependent apoptotic pathway of HCT-15 cells. It abolished the elevation of intracellular Ca(2+), and furthermore, completely inhibited the production of H(2)O(2). These results indicate that cytosolic Ca(2+) elevation is an earlier signaling event in apoptosis of HCT-15 cells. Collectively, our data demonstrate that DADS can induce apoptosis in HCT-15 cells through the sequential mechanism of Ca(2+) homeostasis disruption, accumulation of H(2)O(2), and resulting caspase-3 activation.

Herba houttuyniae has been used as a constituent of herval medicine prescriptions for the treatment of inflammation, cancer, and other diseases. In the present study, we investigated the cellular effects of herba houttuyniae extract (HHE) and the signal pathways of HHE-induced apoptosis in HL-60 human promyelocytic leukemia cell line. HHE treatment caused apoptosis of cells as evidenced by discontinuous fragmentation of DNA, the loss of mitochondrial membrane potential, release of mitochondrial cytochrome c into the cytosol, activation of procaspase-9 and caspase-3, and proteolytic cleavage of poly(ADP-ribose) polymerase. Pretreatment of Ac-DEVD-CHO, caspase-3 specific inhibitor, or cyclosporin A, a mitochondrial permeability transition inhibitor, completely abolished HHE-induced DNA fragmentation. Together, these results suggest that HHE possibly causes mitochondrial damage leading to cytochrome c release into cytosol and activation of caspases resulting in PARP cleavage and execution of apoptotic cell death in HL-60 cells.
