OBJECTIVE: To investigate the specific cytokine pattern and its profiles in rheumatoid arthritis (RA), we measured the mRNA expression of the IL-4, IL- 2, IFN-r7 and IL-10 in the PBMC s and synovial tissue samples. METHOD: We analyzed the cytokine mRNA copy number semiquantitatively in the fresh PBMC s from 13 rheumatoid patients who were not treated with corticosteroid or DMARDs(disease modifying antirheumatic drugs) which may affect the expression of cytokine and 16 healthy normal controls. Mononuclear cells were separated into three compartment(total PBMC, CD4+ cells, and CD4 cells) by the magnetic bead method. Synovial tissues were obtained from surgical procedure freshly. RNA was extracted from 1x10 cells of each PBMC compartment and synovial tissue. To determine the copy number of cytokine mRNA expression, RT-PCR and dot blot hybridization was performed with the RNA extracted from the samples. RESULT: In CD4+ compartment IFN(interferon)-r mRNA was marginally lower in RA patients(143+114) than in normal control(742+1052, p=0.0517) but IL(interleukin)-4 mRNA expression was higher in RA group(73+50 vs. 32+23 in normal control, p=0.0066). Also in CD4- compartment IFN-r mRNA expression was lower in RA(479+850 vs. 6154+15,059 in normal control, p=0.1875) although it was not significant statistically and IL-4 expression was higher in RA group(308+277 vs. 150+100 in normal group, p=0.0428). In PBMC compartment IFN-1 mRNA expression was also decreased in RA group (148+145 vs. 712 +768, p=0.0148), but IL-4 mRNA expression was marginally increased(186+145 vs. 109+62, p=0.0652). In synovium, interestingly, there was virtually no de novo synthesis of IL-4. CONCLUSION: There is significant difference in cytokine pattern of peripheral PBMC between RA and control group. The main cellular IL-4 source in periph- eral blood is not the CD4+ cells. Also there is significant difference of cytokine pattern between the peripheral blood and eynovium in rheumatoid arthritis.

The survey was carried out on 1,031 primary school children for about 1 month, from June 1, to June 30, 1974, for the purpose of understanding indirectly socio-medical status of a remote rural area, reflecting health status of primary school children. The summarized results were as follows: 1)The average age of surveyed children according to school year by sex was older in girls than in boys. The entrance in school at suitable age was peaked as 80.9% in boy of 5th school year and 72.4% in girls of 3rd school year, and also sunk 68.8% in boy of 2nd school year and 58.7% in girls of 1st school year. 2) Prevalence rate according to W. H. O. diseases classification during last a month and a year. a) During last month: The diseases of respiratory system remarked the highest 101.1 in boys and 116.6 in girls. The next were diseases of digestive system (24.2 in boys and 32.1 in girls). The girls were higher than boys in prevalence rate. b) During last year: The diseases of digestive system ranked the highest 133.0 in boys and next, the diseases of respiratory system (108.6 in boys). c) Present illness: Number of code III ranked the highest 129.2 and next XII(127.3) in boys but inverted in girls such as XII(144.9) and III(116.7) and also, Number of code XVII was prevalence twice in boys than in girls. d) Chief complaints by sex: Abdominal pain ranked the highest 71.2 per 1,000 population and next headache (34.7) in boys but headache ranked the highest 88.5 and next abdominal pain (63.3) in girls. e) Water drinking habit: Number of code IX was higher in habit of raw water drinker than in habit of boiled water drinker and healthy children were higher in boiled water habit group than in raw water habit group. The diseases of respiratory system were the highest 124.74 in girls and next, the diseases of digestive system (52.3 in girls). According to school year, healthy children were increased to higher grades. 3) Average sick day per total surveyed children and patient during last months and last year. a) Per surveyed 1,031 children was 0.28 days during last month and 0.98 days during last year. And also per patient was 1.78 days during last month and 3.22 days during last year. b) Average sick day was higher in girls than in boys during last month, but inverted during last year. 4) Average absented day per total surveyed children and patient during last month and last year. a) Per survived 1,031 children was 0.43 days during last month and 3.81 days during last year. b)Per absented children were 2.0 days during lst month and 7.10days during last year. c)Per absented children were 8.16 days in boys and 3.17 days in girls. 5)Utilization of medical facilities: The drug store was consulted 91.2% of the total utilized boys and girls. The strengthening of medical facilities and medical care activities in health subcenter is urgently required. 6)Medical Expense by period and sex: a) Average medical expense per surveyed 1,031 children were 35.95 won, per patient were 298.04 won during last month. b) Average medical expenses per survey children (omitted 1st school year) were 80.56 won, per patient were 243.98 won and per treated patient were 318.87 won during last year. c) Medical expenses were higher in boys than in girls. 7) Rohrer index by sex, present illness and school year. a) Average Rohrer index was 129.8 in boys and 126.2 in girls. b)Average Rohrer index was increased for 1st school year to 2nd school year and thereafter falling down step by step by school year. c) Under 151-160 Rohrer index number of code III was the highest and above 151-160 Rohrer index of code was peaked.

BACKGROUND: Aphasia is common in stroke patients. However, studies about characteristics and prog- nosis of aphasia by acute ischemic stroke were insufficient. The aim of this study is to disclose vascular lesions causing aphasia symptom and to evaluate and clarify types, severity and recovery patterns of vascular aphasia using quantitative aphasia test. METHODS: Twenty six patients were included in this study, who had aphasia symptoms due to acute ischemic lesions confirmed by MRI or CT. Standardized test of Korean version-the Western Aphasia Battery (K-WAB) was performed in all subjects in acute stagte of stroke and was repeated 3 month later. Based on neuroimaging findings and results of aphasia tests, we divided all subjects into two groups, cortical aphasia and subcortical aphasia, and classified further into 8 types. The severity of aphasia measured by aphasia quotient (AQ) was graded. Changes in aphasia types and AQ and prognosis between cortical and subcortical aphasia was analyzed. RESULTS: Various vascular lesions caused aphasia symptoms in cortical and subcortical areas with good clinico-anatomical correlations. Eighteen patients(69.2%) had cortical aphasia and 8(30.8%) had subcor- tical one. Among 8 types of aphasia, 7 types were detected in our patients, and the most frequent type is global aphasia(30.8%). The mean incremental score of AQ between initial and follow-up test was 21.1+/-14.0. The distribution of severity of aphasia was as follows; grade I, 3.8%; grade II, 19.2%; grade III, 42.3%; and grade IV, 34.6%. Twenty one patients(80.8%) were followed up 97.9+/-7.4 days after initial test. Subjects who showed improvement in aphasia were 13(61.9%). Nine out of 13 belonged to cortical aphasia group and 4 out of them belonged to subcortical aphasia group. There was no significant difference in prognosis between cortical and subcortical aphasia group(p=0.58). CONCLUSION: Our study discloses various acute vascular lesions cause aphasia. It also provides cha- racteristics of patients with aphasia by acute ischemic stroke, such as types, severities and recovery patterns, which may help to assess vascular aphasia and its prognosis.

Bile peritonitis due to spontaneous perforation of choledochal cyst is a rare disease and the etiology of spontaneous perforation is unknown in most of infant cases. Recently, we experienced a case of bile peritonitis caused by spontaneous perforation of choledochal cyst in a 6 month-old female infant. She had progressive abdominal distention with ascites, mild jaundice and intermittent passage of acholic stool. Presence of bile in ascitic fluid was revealed by peritoneal tapping. Bile peritonitis from the perforation of choledochal cyst was confirmed by explorative laparotomy and operative cholangiogram. She had discharged with good condition after choledochal cystectomy and Roux-en-Y choledochojejunostomy. A brief review related literatures is also presented.
