PURPOSE: Retrospective study was performed about the incidence, type and pattern of tears, and clini-cal results after arthroscopic management for the symptomatic discoid lateral meniscus. MATERIALS AND METHODS: 54 cases in 49 patients who were managed arthroscopically and followed up for minimum one year for the symptomatic discoid lateral meniscus from Sept. 1993 to Aug. 1998 were included. Mean age at the time of surgery was 30.9 years(ranged, 12-63), most commonly in the second decade(42.5%) and mean duration of symptoms was 22.2 months. Females were more commonly affected than males(25 males and 29 females), and right knees were involved in 25 cases, left knees in 19 cases and bilateral in 5 cases. Most common symptoms was pain in 83.3% and snapping sound in 43.3%. The cause of symptoms was mostly related to previous trauma or sports injury in 66.7%, but none in 18 cases(33.3%). Discoid meniscus was classified according to the Watanabe's classification system and tears were classified as a transverse, longitudinal, horizontal with cystic degeneration, peripheral, wear in the inferior surface and complex. All the partial meniscectomies were done by a piecemeal fashion and the menisci were sutured in a vertical and horizontal way by inside-out or outside-in technique on the basis of day surgery. Postoperative regimens of the immediate passive and active ROM and quadriceps setting exercises were prescribed, and mean follow-up was 31.7 months(ranged, 12-62). RESULTS: According to the Ikeuchi's scale(1969), overall 83.4% of good or excellent clinical results were obtained and poor in 2 cases. Among 5 cases of retear, 3 cases showed excellent clinical results after the second arthroscopic treatment, and 1 case was fair, but 1 case progressed to arthrofibrosis which was rated poor result, and in another one case of poor result without retear, persistent pain was complained due to preexisting osteoarthrosis. CONCLUSIONS: Arthroscopic partial meniscectomy or reshaping is recommmended for the symptomatic discoid lateral meniscus tears in children and adults, but more long-term follow-up and its clinical results about the treatment method in children and adults will be needed.

DiGeorge syndrome is the developmental anomalies of the third and fourth pharngeal pouches. Recently, damages or abnormal development of the neural crest is suggested as a possible pathogenetic factor, because neural crest cells play a crucial role in development of pharyngeal pouch derivatives, e.g. thymus and parathyroid glands, as well as the aortic arches and conotruncal part of the heat. Most cases have abnormal findings of chromosome 22 and are sporadic, but familial cases have been described. Typical features of DiGeorge syndrome are congenital heart disease, aplasia or hypoplasia of the thymus and parathyroid glands and facial dysmorphism. The main problems and cause of death are severe congestive heart failure due to cardiac anomlies, hypocalcemic complications or immunocompromised conditions. As these results, most cases were expired at infantal period or early childhood. Recently, we have a case of Digeorge syndrome which was associated with complex cardiovascular anomalies(tetralogy of Fallot, atrial septal defect, right aortic arch, left hemitruncus), severe hypocalcemia, aplasia of thymus and facial dysmorphism.

BACKGROUND: Hepatitis B virus (HBV) DNA quantification is necessary for starting and monitoring of antiviral therapy in patients with chronic hepatitis B. This study was intended to assess the clinical performance of Abbott RealTime HBV Quantification kit (Abbott Laboratories, USA). METHODS: The performance was evaluated in terms of precision, linearity, detection sensitivity, cross-reactivity, and carry-over. A correlation with the Real-Q HBV Quantification kit (BioSewoom Inc., Korea) was also examined using serum samples from 64 patients diagnosed with chronic hepatitis B and underwent lamivudine therapy in Asan Medical Center. We verified the trueness of the system by comparing the outputs with the assigned values of the BBI panel (BBI Diagnostics, USA). RESULTS: Within-run and between-run coefficients of variation (CV) were 3.56-4.71% and 3.03-4.98%, respectively. Linearity was manifested ranging from 53 to 10(9) copies/mL and the detection sensitivity was verified to be 51 copies/mL. None of hepatitis C virus showed cross-reactivity. No cross-contamination occurred when negative and positive samples were alternatively placed in a row. It showed a good correlation with the Real-Q HBV (r2=0.9609) and the test results for the BBI panel were also well agreed to the assigned values (r2=0.9933). CONCLUSIONS: The performance of Abbott RealTime HBV Quantification kit was excellent; thus, it should be widely used in starting and monitoring of antiviral therapy in Korean patients with chronic hepatitis B.

Pueraiae Radix (PR), Pueratia Folium (PF) and Sorbus commixta (SC) mixture, namely GS-SP (PR (1)/PF (2)/SC (0.5): v/v/v) was developed as hangover-relieving elixir and its effects on alcoholic metabolism have been investigated. The enzymatic activity of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase (ALDH) of GS-SP was shown higher than those of single treatment with PR, PL, SC, and the positive control group (YM-808). The survival rate of mouse liver cell line NCTC clone 1469 in the presence of acetaldehyde was 30.6, 22.2, and 8.7% at the GS-SP dosage level of 50, 100, and 200 microg/mL respectively. Different concentrations of 50, 100 and 200 mg/kg of GS-SP showed efficient activity for ADH and ALDH than YM-808 in rat fed with 25% ethanol. The levels of blood alcohol and acetaldehyde after oral administration of 200 mg/kg of GS-SP showed efficient activity of 11.7% and 37% than those of YM-808. These results have been supported to the potential for GS-SP to serve as an excellent potential in providing hangover relief and liver protection.

The antioxidant activity of white ginseng was not recorded in Korea Functional Food Code, while its activity of red ginsengs was recorded. The aim of this study was to evaluate the antioxidant and hepato protective effect of different ginsengs in H2O2-treated HepG2 cells. White and red ginseng were prepared from longitudinal section of the same fresh ginseng (4-year old). The whole parts of white and red ginsengs were separately extracted with 70% ethanol and distilled water respectively, at 70 degrees C to obtain therapeutic ginseng extracts namely, WDH (distilled water extract of white ginseng), WEH (70% ethanol extract of white ginseng), RDH (distilled water extract of red ginseng) and REH (70% ethanol extract of red ginseng). In this work, we have investigated the DPPH, hydroxyl radical, Fe2+-chelating activity, intracellular ROS scavenging capacity and lipid peroxidation of different ginsengs. All these extracts showed a dose dependent free-radical scavenging capacity and a ROS generation as well as lipid peroxidation was significantly reduced by treatment with bioactive extracts of white ginsengs (WDH) than red ginsengs. Additionally, white ginseng extracts (WDH) has dramatically increased intracellular antioxidant enzyme activities like superoxide dismutase and catalase in H2O2-treated HepG2 cells. All these results explain that administration of white ginseng is useful as herbal medicine than red ginseng for chemoprevention of liver damage.

BACKGROUND: Since free light chain (FLC) is metabolized in the kidney, serum FLC concentration and kappa/lambda ratio are increased in patients with decreased renal function, even in the absence of monoclonal protein. In this study, we measured serum FLC levels to investigate the change in kappa/lambda ratios in relation to the severity of renal dysfunction. METHODS: Serum FLC concentrations were measured in 92 archived serum samples from patients diagnosed with chronic kidney disease using the Freelite assay (The Binding Site Group Ltd., UK), and kappa/lambda ratios were calculated. Serum creatinine levels were assayed to calculate estimated glomerular filtration rate (eGFR), and patients were divided into subgroups according to Kidney Disease Improving Global Outcomes (KDIGO) guidelines. We analyzed the difference in serum FLC levels and kappa/lambda ratios between subgroups. RESULTS: Serum FLC levels and kappa/lambda ratios increased depending on the severity of renal dysfunction. When patients were classified by setting cut-off value of eGFR as 60 mL/min/1.73 m2 (group A: eGFR ≥60 mL/min/1.73 m2, group B: < 60 mL/min/1.73 m2), the kappa/lambda ratio of group B was significantly higher than that of group A (group B: 1.60±0.46 vs. group A: 1.35±0.27, P=0.018). Serum FLC kappa/lambda ratios were within the previously determined renal reference interval (0.37–3.1). CONCLUSIONS: When interpreting results of serum FLC kappa/lambda ratio, renal function status should be considered in addition to hematological findings. If renal function deteriorates, a wider renal reference interval is preferred instead of the usual reference interval.

PURPOSE: To evaluate the results of iliac artery angioplasty and stent placement as an option for the treatment of aortoiliac occlusive disease. METHOD: The records of 30 patients (mean age, 65.5 years) who underwent iliac artery angioplasty and/or stent placement were reviewed retrospectively. Presenting symptoms included asymptomatic (6.7%), claudication (73.3%), rest pain (10%), ulceration/tissue loss (3.3%), and blue toe syndrome (6.7%). Follow-up included angioplasty, Doppler ultrasound, and clinical examination. Mean follow-up time was 32 months. RESULT: Forty iliac lesions were treated. Thirty-seven percent of patients had hypertension, 33% had diabetes mellitus, 23% had coronary arterial disease, 6.6% had cerebrovascular disease, 3.3% had hyperlipidemia and 3.3% had renal insufficiency. TASC (Trans Atlantic Inter-Society Consensus) A, B, C and D disease types were 11 (36.7%) patients, 5 (16.7%), 10 (33.3%) and 4 (13.3%). Ipsilateral superficial femoral artery occlusion was present in 6 (20%) patients. Concomitant femoral artery bypass surgery was performed in 10 (33.3%) patients. The cumulative primary patency rates were 83.4%, 71.9% and 64.7% at 1, 2, and 3 years, respectively. CONCLUSION: Iliac artery angioplasty and stent placement is a technically safe and effective treatment modality in patients without ipsilateral superficial femoral artery occlusion.

BACKGROUND: Brain-death donation became legal in Korea after "The law of organ transplantation" was established at 2000. Therefore, in this study, we report on the clinical analysis of brain-death donors at Ajou University Hospital since the Korean Network for Organ Sharing (KONOS) was launched in the year 2000. METHODS: We reviewed 90 brain-death donors who were managed at Ajou University Hospital from 2000 to 2009 and we retrospectively analyzed the clinical characteristics. RESULTS: The number of brain-death donors was 29 from 2000 to 2005 and 61 from 2006 to 2009, and this showed an increasing tendency. Forty-three brain-death donors (47.8%) were detected at our hospital and 47 donors (52.2%) were from referring hospitals. The percent of brain-death donors at our hospital was 31.0% from 2000 to 2005 and 55.7% from 2006 to 2009 (P=0.042). The mean age of the brain-death donors was 36.3 years (range: 8 months~70 years) and the fifth decade was the most common (25.6%). The gender ratio showed significant difference (P=0.001); there were 60 male donors (66.7%) and there were 30 females (33.3%). The most common cause of brain-death was cerebrovascular disease/stroke (48 donors, 53.3%) followed by traffic accident (15 donors, 16.7%). The most common blood type was Rh+ O (35.6%). The mean number of harvested organs was 3.9 and one donor (1.1%) had the largest number of harvested organs (9) (liver, 2 kidneys, pancreas, heart, lung, 2 corneas, tissue). The mean time to procurement was 3.6 days (range: 2~24 days). CONCLUSIONS: We recommend active discovery and evaluation of brain-death donors in all the hospitals including the hospital organ procurement organization (HOPO).

BACKGROUND: Acute erythroleukemia (AEL), FAB-M6 is a rare heterogenous disorder diagnosed by myeloblasts more than 30% of nonerythroid cells (NEC). Pure erythroleukemia (Di Guglielmo disease) with an excess of proerythroblasts can be classified as MDS or M0. An aberration of the p53 gene in acute myelogenous leukemia is rare, but related to complex karyotypes with poor prognosis. METHODS: To evaluate heterogenous features, 32 cases of AEL or suspicious AEL were categorized as consisting of more than 50% erythroblasts and M6a with more than 30% myeloblasts of NEC, M6b with more than 30% proerythroblasts of all erythroblasts, and M6c with more than 30% both myeloblasts and proerythroblasts. The relation of the p53 protein overexpression and chromosomal abnormalities to AEL and these subtypes was investigated. RESULTS: There were 18 M6a, 6 M6b, and 8 M6c. The percentage of erythroblasts was M6a 58.7%, 77.7% M6b, and 67.2% M6c. The percentage of myeloblasts in NEC was M6a 53.6%, M6b 4.3%, and M6c 39.2%. The percentage of proerythroblasts in all erythroblasts was M6a 5.6%, M6b 56.2%, and M6c 34.1%. Survivals of M6b and M6c were significantly shorter than M6a (12.0 vs. 2.0 vs. 2.0 months, P=0.003). Five of 11 cases showed complex karyotypes (1 M6a, 2 M6b, 2 M6c), of -5, 5q-, -7, 7q-, -17 and/or 17p-, with shorter survival and poor response. The p53 protein overexpression was M6a 27.3%, M6b 100%, and M6c 83.3%. The p53 protein overexpression was positive in all 5 cases of multiple complex karyotype with frequent treatment failure or shorter survival, but was negative in 5 normal karyotypes. CONCLUSTIONS: The occurrence of complex karyotypes and aberration of the p53 gene frequently observed in M6b and M6c subtypes of acute erythroleukemia would be considered in establishing a new and innovative treatment to target neoplastic proerythroblasts that are resistant to standard therapy for acute myelogenous leukemia.
