Severe complications associated with EV71 infections are a common cause of neonatal death. Lack of effective therapeutic agents for these infections underlines the importance of research for the development of new antiviral compounds. In the present study, the anti-EV71 activity of norwogonin, oroxylin A, and mosloflavone from Scutellaria baicalensis Georgi was evaluated using a cytopathic effect (CPE) reduction method, which demonstrated that all three compounds possessed strong anti-EV71 activity and decreased the formation of visible CPEs. Norwogonin, oroxylin A, and mosloflavone also inhibited virus replication during the initial stage of virus infection, and they inhibited viral VP2 protein expression, thereby inhibiting viral capsid protein synthesis. However, ribavirin has a relatively weaker efficacy compared to the other drugs. Therefore, these findings provide important information that will aid in the utilization of norwogonin, oroxylin A, and mosloflavone for EV71 treatment.

OBJECTIVE: To evaluate risk factors for massive lymphatic ascites after laparoscopic retroperitoneal lymphadenectomy in gynecologic cancer and the feasibility of treatments using intranodal lymphangiography (INLAG) with glue embolization. METHODS: A retrospective analysis of 234 patients with gynecologic cancer who received laparoscopic retroperitonal lymphadenectomy between April 2006 and November 2015 was done. In June 2014, INLAG with glue embolization was initiated to manage massive lymphatic ascites. All possible clinicopathologic factors related to massive lymphatic ascites were determined in the pre-INLAG group (n=163). Clinical courses between pre-INLAG group and post-INLAG group (n=71) were compared. RESULTS: In the pre-INLAG group (n=163), four patients (2.5%) developed massive lymphatic ascites postoperatively. Postoperative lymphatic ascites was associated with liver cirrhosis (three cirrhotic patients, p<0.001). In the post-INLAG group, one patient with massive lymphatic ascites had a congestive heart failure and first received INLAG with glue embolization. She had pelvic drain removed within 7 days after INLAG. The mean duration of pelvic drain and hospital stay decreased after the introduction of INLAG (13.2 days vs. 10.9 days, p=0.001; 15.2 days vs. 12.6 days, p=0.001). There was no evidence of recurrence after this procedure. CONCLUSION: Underlying medical conditions related to the reduced effective circulating volume, such as liver cirrhosis and heart failure, may be associated with massive lymphatic ascites after retroperitoneal lymphadenectomy. INLAG with glue embolization can be an alternative treatment options to treat leaking lymphatic channels in patients with massive lymphatic leakage.

A 24-year-old male visited our hospital because of pain in both flanks. His biochemistry profile showed an elevated serum creatinine level and low serum uric acid level. History taking revealed that he had undertaken exercise prior to the acute kidney injury (AKI) event, and he stated that family members had a history of urolithiasis. His renal profile improved after hydration and supportive care during hospitalization. Although the patient was subsequently admitted again due to AKI, his status recovered with similar treatment. Since the diagnosis of the patient was familial renal hypouricemia with exercise-induced AKI, we performed genotyping of SLC22A12, which encodes human urate transporter 1. The diagnosis was confirmed by the detection of a homozygous mutation of W258X. We herein, report a case of familial renal hypouricemia confirmed by genotyping of SLC22A12, and review the relevant literature.

A 50-year-old woman presented with recurrent pancreatitis and pancreas divisum. Minor papilla sphincterotomy and endoscopic stent placement were done for the drainage of dorsal pancreatic duct. After stenting of the minor papilla, abdominal pain has disappeared and pancreatitis has not developed during 9 month follow-up.

Patient with compalints of swelling, pain in the maxillary region and discomfort visited Seoul National University Dental Hospital in August last year. Clinical examination and diagnostic imagings implied he was suffered from fungal h yphal infection but no causative fungus was found by the histopathologic and microbiologic investigation. Therefore he w as diagnosed with nonspecific inflammation. But as yet, we do think this case is very similar to some kinds of mucomycos is. So we presented this case for more thorough discussion. Following are founded in the examination. 1. Patient had sufferd from Diabetes mellitus and complained of stuffness, headache, swelling in buccal cheeks and pare sthesia. And we found more maxillary bony destruction and ulcer with elevated margin in the palate by clinical examinati on. 2. In the first visit, Plain films revealed general bony destruction of the maxilla, radiopaqueness in the sinonasal ca vities. CT and MRI showed soft tissue mass filled in the paranasal sinus except frontal sinus and bony destruction in in volved bones. 3. No causative bacteria and fungus was found in the biopsy and microbiologic cultures. 4. Caldwell-Luc operation and curettage were carried and antibiotics were taken for 4 months. But now he was worse than in the past. 5. In the second visit, involvement of orbit, parapharyngeal sinus, clivus, cavernous sinus and middle cranial fossa we re seen clearly in the CT and MRI.

Primary mediastinal nonseminomatous germ cell tumor associated with Klinefelter's syndrome is a rare disorder. We experienced a case of recurred primary mediastinal nonseminomatous germ cell tumor developed in a 24-year-old patient with Klinefelter's syndrome. The patient had been treated with surgery and combination chemotherapy under the diagnosis of primary mediastinal nonseminomatous germ cell tumor before. A round mass was found on the right lower lung field in the chest X-ray during follow up. The patient was diagnosed as recurred primary nonseminomatous germ cell tumor and Klinefelter's syndrome through tumor markers, peripheral blood karyotyping, and other tests including hormonal assay and was treated with combination chemotherapy and surgery again. When the patient is diagnosed as primary mediastinal nonseminomatous germ cell tumor, Klinefelter's syndrome and hematologic malignancies should be considered to be associated diseases and vice versa.

OBJECTIVES: To evaluate the efficacy and safety of radiation synovectomy with Dy-165 HMA in chronic rheumatoid synovitis of the knee METHODS: Two hundred thirty six knees of 212 patients with rheumatoid arthritis and persistent synovitis of the knee were treated with the intraarticular injection of 250~300 mCi of Dy-165 HMA which was prepared by KAERI. Efficacy was assessed by the following parameters: visual analog scale of the knee pain while walking and resting, circumference of the knee, range of motion of the knee. The final global assessment was classified as good, fair or poor. Estra-articular leakage of Dy-165 HMA was determined by blood pool and urine radioactivity and scintigraphic evaluation of liver, groin, and knee joints. RESULTS: l) The optimum radiation dose was 260mCi. 2) The mean follow up periods were 50.4(24-112) weeks. 3) Forty four percent of the knees showed good results, 32% fair results, and 24% shwoed good results. 4) In knees with stage I radiographic changes, 81% showed improvement, of which 54% showed good results. In knees with stage II changes, 78% showed improvement including 39% of the patients with good results. There was a direct correlation between the radiographic stage and response to treatment. 5) The mean period of improvement for the 180 knees that reponded to treatment was 41.4(24-106) weeks. Ten of the 180 knees with improvement relapsed after the mean period of 64(28-80) weeks. 6) Leakage of radioactivity from the injected joint was minimal. 7) Adverse reactions were rare(radiation burn : 4, transient postinjection "flare" : 14). CONCLUSIONS: The optimum radiation dose in Korean was somewhat less than of other foreign reports. Dy-165 HMA radiation synovectomy is a safe and useful therapy for chronic synovitis of the knee joint.
