OBJECTIVE Licorice is used throughout the world as a traditional herbal remedy. Ac-cording to Chinese traditional medicine licorice alone can be used to treat inflammation.Although there have been some studies investigated the anti-inflammatory ingredients of licorice, but for the potency of flavonoid glycoside and their aglycones on inflammation are not evaluated.This study was designed to assess the contributions of licorice flavonoid glycosides and their aglycons to its anti-inflammatory and hypnotic effects. METHODS For the flavonoid aglycone's enrichment, the extract of licorice (EL) was fermented in submerged culture of the edible fungus Grifola frondosa HB0071 mycelia which can produce β-glucosidase and catalyze the flavonoid glycosides to aglycones.EL and fermented extract of licorice (FEL) were used in this study. The anti-inflammation test was carried out in arachidonic acid (AA)-induced ear edema model and the hypnotic test was performed by using electroencephalogram (EEG)analysis method in normal freely moving SD rats.The chemicals constituents were analyzed by HPLC.RESULTS During fermentation,the falvonoid glycosides of licorice were hydrolyzed by the time process.Along with fermentation time,the concentration of the major flavonoid glycosides,liquiritin and isoliquiritin were decreased obviously, and simultaneously their aglycons, liquiritigenin and isoliquiriti-genin were remarkably increased in FEL.Moreover,the content of another major constituent glycyrrhi-zic acid and glycyrrhetinic acid were not changed after the fermentation. In AA-induced mice ear ede-ma test,after topical application,FEL(effective dose range:5-20 μg·ear-1)showed more potent inhibito-ry activity than EL(effective dose range:25-100 μg·ear-1).On the other hand,oral administration of EL and FEL exhibited the same hypnotic potency and both enhanced the total sleep time including rapid eye movement (REM) sleep and non-REM sleep time. CONCLUSION These results suggested that the enrichment of flavonoid aglycons such as liquiritigenin and isoliquiritigenin enhanced the anti-inflam-matory potency of licorice extract,and this potentiation has nothing to do with glycyrrhizic acid or glycyr-rhetinic acid.In addition,enrichment of flavonoid aglycones did not alter the hypnotic effect of licorice.

Hemophagocytic syndrome (HPS) is a rare but potentially life-threatening disease in kidney transplant recipients, and is caused by systemic proliferation of macrophages actively phagocytizing other blood cells in the bone marrow, lymph nodes, and the spleen.Here, we report a 40-year-old male kidney transplant recipient who presented with fever, bicytopenia, and elevated liver enzymes 2 months after transplantation. Given that cytomegalovirus antigenemia and real-time polymerase chain reaction tests were positive, liver biopsy was performed under an assumption of cytomegalovirus-induced hepatitis. Hepatic histology revealed multifocal microabscess with cytomegalovirus inclusion bodies, marked Kupffer cell hyperplasia, and erythrophagocytosis by activated macrophages. As laboratory findings such as hyperferritinemia, elevated serum lactate dehydrogenase, low natural killer cell activity, and high soluble interleukin-2 receptor were also compatible with HPS, the recipient was diagnosed as having cytomegalovirus-induced hepatitis combined with reactive HPS. Following intravenous ganciclovir therapy with continuous administration of tacrolimus and corticosteroid, the symptoms resolved and laboratory findings were normalized. As far as we know, this is the first report of cytomegalovirus-induced hepatitis combined with reactive HPS in a kidney transplant recipient that is diagnosed by liver biopsy.

The corpus callosum is the main interhemispheric connection in human brain. Agenesis of corpus callosum may partial or complete, and it may have not functional abnormalities. Its prenatal sonographic diagnosis is difficult because of fetal head position, especially in a cephalic presentation. We experienced a case of complete agenesis of corpus callosum. The prenatal sonographic findings was disproportionate dilatation of lateral ventricle, which were suggestive finding of agenesis of corpus callosum or hydrocephalus. We could confirm the diagnosis of complete agenesis of corpus callosum by postnatal MRI.

PURPOSE: In developed countries, acute rheumatic fever appears to be a vanishing disease. In Korea, the incidence and severity of acute rheumatic fever (ARF) has significantly decreased in recent 30 years. According to this report, Korea sustained low incidence of ARF. METHODS: The medical records of 5 children diagnosed as ARF from January 2000 to September 2006 were reviewed retrospectively about clinical manifestations and laboratory findings. RESULTS: The average incidence of rheumatic fever was 0.17 per annual pediatric in-ward 1,000 patients. During study period, only 1 case had a definite history of preceding infection. Among 5 patients, the incidence of major manifestations were as follows:carditis 5 cases, chorea 1 case, arthritis 1 case and erythema marginatum 2 cases. Clinical findings of carditis were cardiac murmur, cardiomegly, congestive heart failure and pericardial effusion. Significant valvular lesions were mitral and aortic insufficiency. Minor manifestations and other clinical manifestations were fever, arthralgia, dyspnea, coughing, palpitation, weakness and chest pain. Laboratory findings were increased antistreptolysin O titer, positive C reactive protein (CRP) and increased erythrocyte sedimentation rate (ESR). CONCLUSION: The incidence of ARF has reduced but rheumatic carditis varies in severity from moderate to severe cardiac involvement. For many reasons ARF is being diagnosed inappropriately resulting from lack of awareness about the disease due to rarity and secondary prophylaxis. We should be aware of acute rheumatic fever and should pay attention to the treatment of the patients with streptococcal pharyngitis.

The aim of this case study was to report the clinical outcome of immediate provisionalization using one-piece narrow diameter (3.0mm) implants in missing maxillary lateral or mandibular incisors. The present study included 36 patients who were treated with 62 one-piece narrow diameter implants. After implant placement, immediate provisional restorations were delivered. All implants showed favorable osseointegration and after progressive loading from 3 months to 9 months (average of 5 months), final restorations were completed without failure in all cases. A survival rate of 100 % (62 of 62) was observed up to 23 months of observation (average of 12.6 months).

BACKGROUND: Obligatory continuing medical education was applied by medical law for lifelong education to Physicians in Korea. A new method of continuing medical education was needed because of wide -spread and easy access to internet which resulted in improved public knowledge medicine, and appearance of a new internet site for doctor's continuing medical education. METHODS: A questionnaire was sent twice by mail and fax to randomly selected 256 office based family physicians in Seoul and Kyonggi Province in May 2001 and 124 available responses were received. RESULTS: The response rate to the questionnaire was 60.77, Median studying time Per week for the past one year of the responders was 3 hours and there was no significant correlation studying time per week with duration in practice, age, sex, or internet accessibility at clinic. The group with more than or equal to 6 years in duration of practice was significantly more than the group with less than or equal to 6 years in number of subscribing medical journals (P=0.001), number of participating academic conferences (P=0.027) , number of participating lectures for office based physicians (P=0.001) and points of formal continuing medical education (P=0.002). The practice pattern change after attendance was 51.3% in 5years or less in duration of Practice, 42.7% in 6years or more. Main causes of being reluctant to attend continuing medical education activities were'no practical content' and' long distance'. CONCLUSION: For the improvement of quality of care by continuing medical education, practical program applicable to the clinical practices should be developed and continuing medical education activities be carried out in various areas.
