Up to the present there were the blood transfusion and the use of apparatus not to sterilize at surgical operation and medical treatments in well known infectious ways of hepatitis B virus. But all its ways were still not surely known. As the other ways of hepatitis B virus infection, it was suggested that contagion such as kissing, sexual contact, homosexuality, and varieties discharged out human body urine, stool, tear, salivary, menstrual blood, Vaginal discharge etc, and low economic status, unsanitary environmental life, alcohol and smoking related to hepatitis B virus infection. From 800 waitress who frequently contact with a lot of drinker with low economic status and unclear environmental life, this study were investigated HBs Ag (Hepatitis B surface antigen) known marker for hepatitis B virus infection in their serum, and a few conditions of their private life in order to known dangerous rate b~ing exposed to the source of hepatitis B virus infection as comparison with control group. The results were summarlized as following 1. The positive rate of HBs Ag (4.3%) was significantly higher in waitress than in control group(1.1%). 2. In waitress old, 20-24 ages group was the most as 59.5%, and positive rate of HBs Ag was trend of higher in twenties than thirties. 3. Among the waitress, one that it was less than a year were the most (62.4%) in the period to work at restaurant business, and positive rate of HBs Ag was trend of higher in propotion to period to work at there. 4. Among the waitress, one who entertained to beer hall was the most (46%), and they were trend of higher in positive rate of HBs Ag (6.3%) than other waitress. 5. Among the waitress, one to drink with smoking, and only to drink, and only to smoke, and not to drink and smoke 66.1%, 21.5%, 4.6% and 7.8%. Espically in one to drink with smoking, ther was trend of indicating the high positve rate of HBs Ag, and it was made suspicion of the relationship of alcohol smoking, contact with a lot of drinker, unclear environment to hepatitis B virus infection. In the above results, it was found that dangerous rate being exposed in hepatitis B virus infection was high in the waitress. Therefore there are required for active preventions against hepatitis B virus infection them. Also as it is possible to be infectious source in public health that waitress infected to viral hepatitis, it is thought that appropriate rules about them.

The result of the screening of lectins on 28 species of marine shell fishes(mollusks) showed that 10 species (Tapes philippinarum, Cyclosunetta menstrualis, Neptunea arthritica cumingii, Omphalius pfeifferi carpenteri, Chlorostoma argyrostoma turbinatum, Chiorostoma argyrostoma lischkei, Semisulcosira corea, Neptunea polycosta, Babylonica japonica, Noverita didyma) were present hemagglutinating properties to human A, B, and O group, and animal blood erythrocytes. A new lectin from Tapes philippinarum. was isolated and partially characterized. The lectin was purified by (NH$_4$)$_2$SO$_4$ precipitation and ion exchange chromatography on DE 53 column. Six fractions were obtained from DE 53 column by salt gradient elution but only 0.3M, and 0.4M NaCl fraction had strong lectin activity. On its 0.3M NaCl fraction, purity was identified by polyacrylamide gel electrophoresis. This lectin was inhibited by N-acetyl-D-galactosamine. It seems that two kinds of lectin react as antigen by immunochemical studies.

Medical personnek are one of several groups that have been reported to have a high incidence of hepatiris B. It is also thought that the occurrence rate of hepatitis B surface antigen(HBsAg), aserologic marker for hepatitis B virus(HBV), is expected to be high in the dental personnel who are frequently exposed to the blood and saliva of the patients. Although many studies have been done to determine the HBsAg status of virus groups, limited investigations have been performed on dental personnel, especially in this country. The main purpose of this study was to identify HBsAg positivity among dental students, interns, and residents who would be expected to be a high risk group of hepatitis B infection. Screening test for HBsAg of a dental school population was performed by indirect hemagglutination(IHA)in 1982. The results were as follows : 1. Thirty four out of a total 362 persons(9.4%)tested in the study had positive response for HBsAg in their serum samples. 2. Twenty seven out of 320 dental students(8.4%)had positive for HBsAg, and in Senior class 12 out of 82 dental students (14.6%)had positive response that was the highest incidence among dental students group. 3. Seven out of 42 interns and residents(16.7%)had positive for HBsAg, and it was the highest incidence in this dental school population.

Purpose: This study compared outcomes in children with acute leukemia who underwent transplantations with umbilical cord blood (UCB), bone marrow, or peripheral blood stem cells from a human leukocyte antigen (HLA)-matched related donor (MRD) or an unrelated donor (URD). Methods: This retrospective study included consecutive acute leukemia patients who underwent their first allogeneic hematopoietic stem cell transplantation (HSCT) at Samsung Medical Center between 2005 and 2010. Patients received stem cells from MRD (n=33), URD (n=46), or UCB (n=41). Results: Neutrophil and platelet recovery were significantly longer after HSCT with UCB than with MRD or URD ($p$ <0.01 for both). In multivariate analysis using the MRD group as a reference, the URD group had a significantly higher risk of grade III to IV acute graft-versus-host disease (GVHD; relative risk [RR], 15.2; 95% confidence interval [CI], 1.2 to 186.2; $p$=0.03) and extensive chronic GVHD (RR, 6.9; 95% CI, 1.9 to 25.2; $p$ <0.01). For all 3 donor types, 5-year event-free survival (EFS) and overall survival were similar. Extensive chronic GVHD was associated with fewer relapses (RR, 0.1; 95% CI, 0.04 to 0.6; $p$ <0.01). Multivariate analysis showed that lower EFS was associated with advanced disease at transplantation (RR, 3.2; 95% CI, 1.3 to 7.8; $p$ <0.01) and total body irradiation (RR, 2.1; 95% CI, 1.0 to 4.3; $p$=0.04). Conclusion: Survival after UCB transplantation was similar to survival after MRD and URD transplantation. For patients lacking an HLA matched donor, the use of UCB is a suitable alternative.

Plants have long been used as a food source in Korea. In this study, we investigated the combined immunomodulative effects of a water extract mixture of(pine needles, Sedum sarmentosum Bunge, hijkiaorme, buckwheat and Peril a leaves) on Balb/c mice $7{\sim}8$ weeks old. The mice were fed a chow diet ad libitum and the plant extract was orally administered every other day for four weeks at two different concentrations(50 and 500 mg/kg BW). After preparing the single-cell suspension, splenocyte proliferation was determined by the MTT(3-[4,5-di-methylthiazol-2-y]-2,5-diphenyl terazolium bromide) assay. After 48hrs of incubation with the mitogens(ConA or LPS) splenocyte from the mice groups administered 50 and 500 mg/kg BW of the plant extract showed a significant increased in proliferation compared to the control group. A hemolytic plague forming cell assay was used to indicate antibody production against sheep red blood cells(SRBC). The number of antibody-secreting cells T-dependent antigen. The result of this study suggest that supplementation with this plant extract may regulate immune function by increasing splenocyte proliferation and the number of plaque forming cells.
