Purpose: Needlestick injuries (NSI) is the most frequent occupational hazard for healthcare personnel (HCP), and immediate report and adequate post-exposure prophylaxis (PEP) is essential in preventing occupational transmission of blood-borne pathogens. Methods: From June 2010 to October 2010, 544 NSI were reported through websites from 21 general hospitals in Korea. Among those, 499 cases of NSI were analyzed to identify the rate of follow-up treatment completion and for seroconversion. Results: 88.2% of the cases were completed with follow-up treatment, 8.8% of the NSI were not completed with follow-up treatment, and 5 cases were unavailable to trace. 4.2% cases of NSI required a hepatitis B vaccination concurrent with hepatitis B immunoglobulin. 41.1% of the cases and 31.1% of the cases needed to be tested for anti HCV and anti HIV, respectively. Prophylaxis medication for HIV was prescribed in 3 cases, and all cases completed required 1 month of medication. There was 1 case (0.2%) of seroconversion to HCV. Conclusion: The PEP completion rate was not satisfactory, and the importance of completion of PEP treatment should be emphasized through education and counseling. Also, a careful risk assessment is needed for HCP who are exposed to HCV or HIV.

Purpose : We compared the therapeutic efficacy of lamivudine and alpha-interferon in children with chronic hepatitis B two years after the initiation of treatment, so that we could verify the safety and long term efficacy of lamivudine in children. Methods : We prospectively studied 44 children(32 male and 12 female; age, 1-18 years, mean, 9 years) treated for chronic hepatitis B from September 1996 to June 2004 in Kyungpook National University Hospital in Korea. Twenty three children were treated with interferon, and 21 with lamivudine. Treatment efficacy was defined as the normalization of ALT and hepatitis B virus(HBV) DNA levels, loss of HBsAg and HBeAg seroconversion at two years after the initiation of treatment. Results : Among the 23 children treated with interferon, the ALT level normalized in 10 children(43 %) and HBV DNA was undetectable in 12 children(52%). HBsAg was undetectable in one child (4 %) and HBeAg seroconversion occurred in nine children(39%) two years after the initiation of treatment. In comparison, among the 21 children treated with lamivudine, ALT normalized in 20 children (95%), HBV DNA in 19(90%), HBsAg in 5(24%), and HBeAg seroconversion occurred in 13(62%). Above all, in the lamivudine treated group under the age of seven, HBeAg and HBsAg seroconversion occurred in six(75%) and five(63%) out of the eight children respectively, which showed superior HBsAg seroconversion rate if treated in preschool aged children. Conclusion : We believe that the therapeutic efficacy of lamivudine in children with chronic hepatitis B could be better than interferon with fewer side effects, especially in preschool aged children.

만성 B형 간염의 경과중 흔히 볼 수 있는 간기능의 이상은 대부분 심한 황달의 동반없이 혈청 AST와 ALT의 증가만 보이면서 악화되는 것이다. 저자는 심한 황달을 동반한 16명의 만성 B형 간염 악화 환자(연구군)와 심한 황달없이 AST와 ALT치만 증가된 13명의 환자(비교군)를 비교관찰하였다. PMC 제재를 복용했던 환자는 연구군에서 11명(68.8%), 대조군에서 1명(7.7.%)으로 나타났으며 PMC를 포함하여 각종 약제 및 알콜 섭취가 저명했던 환자가 연구군에서 15명(93.8%), 대조군에서는 2명(15.4%)이었다. 혈청 HBeAg 양성율은 급성 악화전에는 연구군에서 14명 중 7명(50.0%), 비교군에서는 13명 모두 (100%)에서 양성이었으며, 급성 악화 경과후에는 연구군에서는 변함없었고 비교군에서는 13명중 3명(23.1%)에만 양성이었다. 연구군 중 anti-HBe 양성화는 한 사람도 생기지 않았고 6명이 사망하였으며 대조군에서는 8명의 환자에서 anti-HBe 양성화가 생겼고 아무도 간기능 부전으로 사망하지 않았다. 만성 B형 간질환에서 심한 황달을 동반한 급성 악화와 관련있는 요인은 진행된 만성 활동성 간염, 간경변 등 근본적으로 진행된 간기능 저하와 동반된 부적절한 약제나 알콜 복용이 확실히 관계있을 것으로 사료되며 간기능 부전도 그리 드물지 않다. 반면에 간경변으로 진행되기 전 상대적으로 진행이 덜 된 비교군의 만성 B형 간염 환자에서는 황달의 저명한 증가없이 간기능이 갑자기 악화될 때는 자연적인 혈청 anti-HBe 양성전환의 동반이 흔한 것으로 나타났다.

A modified amidolytic assay and a fibrin plate method were used to accurately measure the concentration of single chain urokinase type plasminogen activator (scu-PA) and two-chain urokinase type plasminogen activator (tc-PA) in the spent media. $1.65{\times}10^6$(viable cells/ml) of maximum cell density and 1670(IU/ml) of scu-PA concentration were obtained in 1% serum containing medium. The overall conversion ratio from scu-PA to tc-PA was less than 10%. In the results of batch cultivation in a spinner vessel, $4.43{\times}10^6(total cells/ml)$ of maximum cell density and 1560(IU/ml) of scu-PA concentration was observed. The maximum scu-PA concentration and specific scu-PA Productivity were obtained in 1760(IU/ml) and $3.13{\times}10^{-4}(IU/cell)$, respectively, from perfusion cultivation. The conveysion ratios from batch, fed-batch and perfusion cultivations were less than 12%, which means that about 90% of scu-PA secreted from the cells can be maintained during the cultivations.

The present study aimed to evaluate the effects of radiation mutant Perilla frutescens var. crispa and Atractylodes macrocephala Koidzumi complex extract(Perilla frutescens var. crispa complex extract) on the mediators related to degenerative arthritis in a monosodium iodoacetate-induced rat model of degenerative arthritis. Perilla frutescens var. crispa complex extract was administered orally at doses of 25, 50 or 100 mg/kg/day for 2 weeks before direct injection of monosodium iodoacetate (3 mg/50 µl of 0.9% saline) into the intra-articular space of the rats' right knees. The rats subsequently received the same doses of oral Perilla frutescens var. crispa complex extract for another 4 weeks. It was evaluated that the treatment effects based on serum bio-markers, and morphological and histopathological analysis of the knee joints. Compared with those in negative control rats, the Perilla frutescens var. crispa complex extract treatments significantly reduced the serum levels of inflammation, bone metabolism markers (i.e., TNF-α, MMP-3, COX-2, PGE₂, COMP, and Aggrecan). Otherwise, it was significantly increased the production of CTX-2 in cartilage absorption mediators. In addition, the Perilla frutescens var. crispa complex extract treatments effectively preserved the knee cartilage and synovial membrane. As a result, it indicates that the Perilla frutescens var. crispa complex extract improved degenerative arthritis symptoms. Thus, the Perilla frutescens var. crispa complex can be used in food material for the management of degenerative arthritis.

Purpose : Marrow edema and fatty degeneration of the hip joint bones could be initial and late signs in hip joint and its bone diseases respectively, which might be differentiated from age-related marrow conversion pattern. So authors have investigated normal marrow conversion pattern of the femur and acetabulum around the hip joints. Materials and methods : Three coronal MR images of 288 hip joint bones in 144 subjects, aged 2 days to 76 years divided to 8 groups every 10 years, were retrospectively analysed for the location and appearance of the converted yellow marrow. The converted yellow marrow were divided to head, neck, and trochanter in the proximal femur and below and above 50% in acetabulum of the hip. Results : The most common type of marrow conversion is the converted yellow marrow in the entire proximal femur and below 50% of acetabulum of the hip. We observed the start of marrow conversion in just before and after 2 years old and stopped at just before and after 20 years old. Conclusion : The understanding of age-related marrow conversion pattern of the hip joint bones would provide some information for differentiation from pathologic condition of them such as edema, fatty degeneration, metastasis, or leukemia.

Total amount of Calories and protein intakes of fishing villagers show higher level than those of farming and mountain villagers, however, the proportion of animal protein (meat protein) in total amount of protein intakes of mountain villagers is much lesser than those of other two villagers. Blood specific gravity, serum protein content and serum tryptophan content were low in inhabitants of mountainous area than those of other two villagers, and in the serum protein fractions, the Albumin Globulin ratio (A/G ratio) show also lower value in inhabitants of mountainous area than those of other two villagers. It is interesting result that serum tryptophan content (serum protein tryptophan) presented a significant positive correlation with that of serum gamma globulin and a significant negative correlation with that of serum albumin. The fact of farming villagers under twenty year old female showing plasma vitamine deficiency phenomenon, however, the plasma carotene value show higher level indicates that the most of the plasma carotene being hardly transfered to the plasma vitamine A in blood. The thiamine value in urine of mountain villagers show higher level than others, it indicates that there is correlation between their poor protein intakes and amount of thiamine ia urine. And the data obtained in the present study could be established by the result of animal experiment reported by Koyanagi et al. and the result of previous paper of auther.

Purpose: The study aimed at monitoring the immune status of health care workers (HCWs) of a tertiary hospital after accidental exposure to Hepatitis B virus (HBV). Methods: Between January 2004 and December 2006, 353 cases of exposure to Hepatitis B virus were reported. The HBV-exposed HCWs were required to undergo follow-up serum tests to analyze their immune status one year after the exposure. The obtained data were then analyzed to determine the incidence of exposure and of sero-conversion. Results: In this hospital, an average of 9.8 cases of Hepatitis B exposure among HCWs was reported in a month. Follow-up tests conducted after exposure revealed that 90.4% of the HBV-exposed HCWs were positive for Hepatitis B antibody and 66.9% of the HBV-exposed HCWs were reported to have antibody levels exceeding 10 mIU/mL. Results of serum tests for the HBV antigen conducted one year after exposure were negative for all the exposed HCWs. Conclusion: Among the 79.6% of the HCWs who underwent serum tests one year after exposure the HBV sero-conversion rate was 0.0%. However, a further investigation in the form of long-term and multi-center studies is required to confirm this result. Furthermore, an active system should be established to ensure that all exposed HCWs undergo follow-up serum tests.
