The present study was undertaken to observe the quality and quantity of lipids in the adult worms of Chinese liverfluke, Clonorchis sinensis. Lipid extraction was done by the methods of Folch et a1. (l957) and Kenny (1952), and then the extracted lipid fractions of the worm were separated by thin layer chromatography. Those fractions were also subjected to perform the quantitative analyses of glycerides, cholesterols and phospholipids. The results obtained were summarized as follows: Total amount of glyceride was 37.56 mg per gram of worm tissue and the amount of monoglyceride was 8.34 mg per gm; diglyceride, 15.46 mg per gm; and triglyceride, 12.86 mg per gm. Total amount of cholesterol was 3.30 mg per gm of worm tissue, and the esterified cholesterol (1.72 mg/gm) was a little more than that of free cholesterol (1.26 mg/gm). The following 8 phospholipids were detected in the worm tissue of C. sinensis, i.e., lysophosphatidylcholine, phosphatidylcholine, phophatidylinositol, sphingomyelin, phosphatidylglycerol, phosphatidylserine, phosphatidylethanolamine and an unknown phospholipid.

Henoch-Shonlein(H-S) purpura, or anaphylactoid purpura is a hypersensitivity vasculitis characterized by palpable purpura usually on buttock and low extremities; arthralgia mostly polyarhtralgia in the absence of frank arthritis; gastraintestinal involvement with colicky abdominal pain, nausea, vomiting, diarrhea, constipation and bleeding; and renal involvement, manifested chiefly by hematuria and proteinuria. Gastrointestinal involvement is seen in 70 percent of pediatric patients and one third of adult patients. Any portion of the gastrointestinal tract distal to the esophagus maybe involved, but most frequently affected sites are jejunum and ileum. We report one case of H-S purpura with duodenal involvement observed in 16, male patient.

PURPOSE: The long term disease course and prognostic factors were evaluated in childhood Henoch-Schonlein purpura nephritis(HSPN). METHODS: A total of 75 children(44 boys and 31 girls) with HSPN were included in this study. The onset age was 8.0+/-3.1 years(2.3-15.3 years), and the follow-up period was 4.3+/-3.6 years(1.0-17.1 years). Kidney biopsy was done in 24 children(32%). Initial clinical and laboratory findings were evaluated. In addition, polymorphisms of the renin angiotensin system(RAS) genes(insertion/deletion in intron 16 of ACE gene, M235T in AGT gene, and A1166C in AGTR gene) were analysed. The initial and last clinical states were classified into 4 groups as follows:A, normal; B, minor urinary abnormalities; C, active renal disease (nephrotic-range proteinuria and/or hypertension with serum creatinine < or =1.5 mg/dL); D, renal insufficiency. RESULTS: At the onset, the clinical states of the patients were B in 26(35%), C in 46(61%), and D, in 3(4%). The distribution of the RAS gene polymorphism of HSPN were not different from that of 100 healthy control subjects. At the last follow-up, the clinical states of the patients were A in 23(31%), B in 38(50%), C in 9(12%), and D in 5(7%). A multiple logistic regression identified age at the onset and initial urine protein excretion as significant prognostic factors. Analysis of genotypes of the 3 RAS genes as prognostic values revealed no statistical significance. CONCLUSION: Older age at onset and severe proteinuria were identified as poor prognostic factors of childhood HSPN. Implication of the RAS gene polymorphism in HSPN could not be validated in this small-scale retrospective study.

Despite the recent increase in the use of complementary and alternative medicine (CAM) among the general population and patients, little is known about Korean physicians' attitudes about and interest in CAM. We conducted a web-based survey of knowledge, attitude, and experience in CAM among primary care physicians (PCPs) and academic physicians (APs) in Korea. A total of 826 physicians (341 PCPs and 485 APs) responded. Respondents in both groups felt that they were not sufficiently knowledgeable about CAM. PCPs, however, had a significantly higher composite index score in CAM knowledge than that of APs. Although APs were more skeptical about the scientific evidence of CAM than PCPs, both groups had a positive attitude toward CAM. The level of experience in utilizing CAM in their practice was 23.2% among PCPs, which was much higher than that among APs (2.7%). Experience rates of referring patients to CAM were 11.7% in PCPs and 4.5% in APs (P<0.001). Despite the discrepant rates in CAM education between the two groups (58.7% in PCPs and 26.0% in APs, P<0.001), the majority of doctors in both groups (85.0% in PCPs and 70.0% in APs) expressed an intention to participate in authorized CAM coursework. In conclusion, despite the lack of scientific evidence, both PCPs and APs have an interest in incorporating CAM into their conventional medical practices. To meet physicians' increasing needs for CAM the Korean medical societies should promote education and research about CAM in the conventional medical system.

BACKGROUND: Unexpected antibody screening and identification tests are very important for safe blood transfusion. The micro-column agglutination test (MCAT) is widely used due to its simplicity and efficiency for detecting alloantibodies. We analyzed the frequency of unexpected antibodies at three university hospital blood banks, which use two different MCAT systems. METHODS: From February 2002 to December 2009, a total of 295,876 unexpected antibody screening tests were performed at three university hospital blood banks. Two hospital blood banks (Anam and Ansan Hospitals) used the DiaMed-ID system (DiaMed Ag, Switzerland) and the other (Guro Hospital) used the Ortho BioVue system (Ortho-Clinical Diagnostics, USA) for antibody screening and identification tests. RESULTS: The rates of detecting unexpected antibodies on screening test based on the 'tests performed' and the 'persons tested' were 1.16% per test and 0.96% per person in Korea University Guro Hospital, 0.65% and 0.41% in Korea University Anam Hospital and 0.76% and 0.57% in Korea University Ansan hospital, respectively. There were significant differences in the frequencies based on the two different systems (P<0.001). Among the warm antibodies, Rh antibodies were more frequently detected by the DiaMed-ID system, and Lewis antibodies were most frequently detected by the Ortho BioVue System. CONCLUSION: We should carefully interpretate the frequency of unexpected antibodies in the Korean population because the frequencies of unexpected antibodies are different according to different employed micro-column agglutination systems.
