PURPOSE: Treatment of Kawasaki disease with intravenous gamma globulin(IVGG), together with aspirin, has been dernonstrated to be safe and effective in preventing coronary artery lesion and systemic inflarnmation, but optimal IVGG dosage and administration method are still controversial. We compared the therapeutic efficacy and clinical response of single IVGG 1g/kg to that of IVGG lg/kg for comparable risk group of Kawasaki disease. METHODS: We conducted a prospective study involving 63 children with Kawasaki disease requiring IVGG treatment(Harada score> or =4) at Chungnam National University Hospital from February 1996 to January 1999. The children were assigned to receive IVGG either as a single infusion of 1g/kg(A group, 32 person) or 2g/kg(B group, 31 person) and aspirn(100mg/kg/day through acute phase, then 3 to 5mg/kg/day for 8 weeks of duration). RESULTS: There were no significant difference between the two groups according to clinical and laboratry data, including coronary artery lesions(group A, 31.3% and group B, 29.0%) before treatment. After IVGG treatment ratio of complication with coronary artery lesion(group A 1/32=3.1% and group B, 2/31=6.5%) and that of retreatment(group A, 4/32=12.5%, group B, 2/31=6.5%), duration of fever(group A, 1.3+/-1.6 days and group B, 0.7+/-1.4 days), hospital stay(group A, 7.0+/-1.4 days and group B, 6.5+/-2.0 days), laboratory finding and side effects of IVGG were not significantly different(P>0.05). The total dosage of IVGG was significantly lower in group A than group B(group A, 1.16+/-0.37g/kg, 375,421+/-207,351won and group B, 2.10+/-0.40g/kg, 641,498+/-274,750won (P<0.05). CONCLUSION: The therapeutic efficacy and clinical response of single 1g/kg therapy are comparable to that of single 2g/kg therapy.

PURPOSE: To investigate the effect of intraperitoneal injection of IGF-I after hypoxic ischemic brain injury on neuronal cell necrosis, apoptosis and expression of proapoptotic and antiapoptotic proteins bax and bcl-2, respectively. METHODS: The right carotid artery was cut between the double ligation. Then allowed to recover for 30 minutes followed by exposure to 8% oxygen at 37degree C for 2 hours. Devided 2 groups, control group(N=30) and IGF-I treated group(N=30). IGF-I treated group received IGF-I 20 microg 2 hours after hypoxic ischemic injury intraperitoneally. Rates were decapitated at 24 hours and 72 hours following hypoxic ischemic brain injury. After then, right hippocampal CA1 and CA3 neuronsof rat brains were examined. RESULTS: The apoptosis and necrosis was significantly less in IGF-I treated group than control group and necrosis was more prominent in CA1 neurons than CA3 neurons. Necrosis was slightly decreased at 72 hours in both groups(P<0.05). The apoptosis was more prominent at 24 hours than 72 hours after hypoxic ischemic injury(P<0.05). Bax protein expression was prominent in control group, especially at 72 hours(P<0.05) and less in the IGF-I treated group than control group. Bcl-2 protein expression was not detected in both group. CONCLUSION: The results from this study suggest that exogenous systemic IGF-I had a neuroprotective effect by inhibition of up-regulation of bax protein expression after hypoxic ischemic brain injury.

OBJECTIVETo establish the method of detecting the concentrations of bisphenol A (BPA)in air of workplaces with high performance liquid chromatographic (HPLC).
METHODSAccording to standards of methods for determining the chemical substances in workplace air, BPA in the air was collected by glass fiber filter, then dissolved by acetonitrile and determined by high performance liquid chromatography with FLD.
RESULTSThere was a linear relationship within the range of 0.01-10.0 pg /ml, and the detection limit was 0.005 pg/ml. The lowest detected concentration was 3.3x10-5 mg/m3. The relative standard deviation was 2.5-5.5%. The dissolution efficiencies were 95.0%-101.9% and the sampling efficiencies were 99.6%. The samples in glass fiber filter membrane could be stored for 7 days at room temperature.
CONCLUSIONThe present method could meet with the requirements of Guide for establishing occupational health standards-Part 4 Determination methods of air chemicals in workplace and be feasible for determination of BPA in workplace air.

ObjectiveThis study aimed to compare the clinical characteristics and prognoses of primary Waldeyer's ring diffuse large B-cell lymphoma (DLBCL) and extranodal nasal-type NK/T-cell lymphoma ( ENKTCL).MethodsFrom 2000 to 2008,122 patients with primary Waldeyer's ring DLBCL and 44 patients with primary Waldeyer' s ring ENKTCL consecutively diagnosed were retrospectively compared.Patients with DLBCL usually received 4-6 cycles of CHOP-based chemotherapy followed by involved-field radiotherapy.Patients with early stage ENKTCL usually received extended-field radiotherapy with or without subsequent chemotherapy,or short courses ( 1 - 3 cycles ) of chemotherapy followed by radiotherapy.Kaplan-Meier method was used for survival analysis.Logrank method was used for univariate analysis.ResultsThe follow-up rate was 82%.The number of patients followed 5 years were 32 and 15 in DLBCL and ENKTCL.DLBCL mainly presented with stage Ⅱ tonsillar disease with regional lymph node involvement.ENKTCL occurred predominately in young males,as nasopharyngeal stage I disease with B symptoms and involving adjacent structures.The 5-year overall survival (OS) and progression-free survival (PFS) rates were 74% and 67% in DLBCL,and 68% and 59% in ENKTCL (x2=0.53,1.06,P=0.468,0.303),respectively.In stage Ⅰ and Ⅱ diseases,the 5-year OS and PFS rates were 79% and 76% for DLBCL compared to 72% and 62% for ENKTCL (x2 =1.20,2.46,P=0.273,0.117).On univariate analysis,age > 60 years,elevated lactate dehydrogenase,eastern cooperative oncology group performance status > 1,international prognosis index ( IPI ) score ≥ 1,stage Ⅲ/Ⅳ diseases and bulky disease were associated with unfavorable survival for DLBCL (x2=9.40,12.72,6.15,10.36,12.48,5.53,P=0.002,0.000,0.013,0.001,0.000,0.019),and only age>60 years and IPI score ≥ 1 were associated with poor survival for ENKTCL (x2 =3.98,8.41,P =0.046,0.004).ConclusionsThese results indicate that remarkable clinical disparities exist between DLBCL and ENKTCL in Waldeyer's ring. Different treatment strategies for each can result in similarly favorable prognoses.
