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.

We introduce a new operative method for acute epidural hematoma(AEDH) through small craniotomy. Between January 1999 and December 2001, 63 patients underwent craniotomy in our hospital to evacuate an acute posttraumatic epidural hematoma. Among these, we operated 18 patients with linear scalp incision and about 4 X 4cm sized small craniotomy. After operation, neurological symptoms were improved and there were no significant postoperative complications in all patients. This operative method is simple and less time consuming. It can be done under the local anesthesia and may be useful to all AEDH without severe brain swelling, subdural hematoma and intracerebral hematoma.

BACKGROUND: This study was conducted to analyze the current system for allocation of deceased donor kidney transplantation in Korea, which includes an incentive regulation for candidates registered at the Hospital-based Organ Procurement Organization (HOPO). METHODS: Between January 2011 and November 2016, there were 2,655 deceased donors in Korea. During the same period, there were 21,247 current candidates and recipients of kidney, pancreas and simultaneous pancreas-kidney transplants. We analyzed data from all of these donors, candidates, and recipients. RESULTS: Mean waiting times for organ allocation of each priority differed significantly (2nd priority group, 1,701±974 days; 3rd priority group, 1,316±927 days; 4th priority group, 2,077±1,207 days). Additionally, HOPO candidates/deceased donor ratios were very different from each other (maximum, 49; minimum, 0.6). The number of deceased donors in region 1, 2, and 3 were 1,623, 429, and 603, respectively, while the number of transplantations in each region was 3,095, 597, and 1,165, respectively. The candidates registered at region 1 HOPO moved the longest distances on average for transplantation, and this value differed significantly different from that of other regions (56.18±91.9 km vs. 24.66±28.0 km vs. 26.20±37.3 km, P<0.05). CONCLUSIONS: The incentive system of current allocation system for deceased donor kidney in Korea does not coincide with the purpose of the ‘Declaration of Istanbul’ and unnecessary social costs have occurred. Therefore, we should make an effort to change our current allocation system to the geographic sequence of organ allocation system.

Coronary stent dislodgement during percutaneous coronary intervention, which occurs when the stent is passed through tortuous and calcified lesions, is not a rare complication. Without proper treatment, such as fixing with another stent in the coronary artery or removing the undeployed stent from the coronary artery or systemic artery system, this complication can cause serious problems. We experienced the unusual situation of a dismounted and dislodged coronary stent, in which retrograde retrieval to the radial artery was impossible during transradial coronary intervention. We report on use of a rendezvous and snare technique at the brachial artery level via femoral puncture, which resulted in resolution without surgery.

OBJECTIVE: The variable operative methods are underwent as a treatment of tuberculous spondylitis. We propose hemilaminectomy and debridement as a one of operative method at a certain circumstance. METHODS: From July 1998 to June 2002, 13 consecutive patients with spinal tuberculosis were treated surgically in our institution. Among them, the authors analysed 7 patients in whom posterior approach were performed. The lumbar spine was involved in 6 patients, the thoracic in 1. The hemilaminectomy with debridement was done in all cases. The changes in the Kyphotic angle and the height of involved vertebras retrospectively measured from lateral spinal radiographs obtained preoperatively and postoperatively. Mean follow up periods were 16 months. RESULTS: Clinical symptoms and signs were improved in all cases. One patient (14%) was needed anterior fusion because of aggravation of lesion. Another one needed reoperation because of relapse of epidural abscess. The arithmethical average of kyphotic angle was worsened about 2 degrees and that of height loss was lesser than 5% postoperatively. CONCLUSION: The hemilaminectomy with debridement for spinal spondylitis can be a first therapeutic modality in a mild neurologic deficit and minor lesions with extended epidural abscess and granulation tissue to the adjacent vertebras in radiologic finding. Especially if epidural abscess and granulation tissue involve the multiple vertebras, we recommend this operative method.
