1.Some discussions of the liver transplatation
Journal of Vietnamese Medicine 2001;263(9):1-5
33 years ago, since the first liver transplantation was performed by STARZL, until now transplantation has travel a long road technical, legal, sociological development. There are now, more than 30,000 liver transplantations having been performed throughout the world. The results has improved since the introduction of cyclosporin. The long-term survival rate are approximately 70-80% at 1 year, 60-70% at 5 years. Some of the patients have now survival for over 20 years-long-term surviving liver transplan patients have a better quality of life. Nervertheless there are the problems limiting the development of liver transplantation: - the inadequate supply of donor organ. - The legal, sociological, ethical and cost effectiveness

3.Significance of Interleukin-6 and Ureaplasma urealyticum Detected by Polymerase Chain Reaction in the Tracheal Aspirates at Birth for the Development of Chronic Lung Disease (CLD) of Prematurity and the Risk Factors for the Different Types of CLD accordin.
Journal of the Korean Society of Neonatology 2004;11(2):170-184
PURPOSE: To analyze the significance of interleukin-6 (IL-6) concentration and Ureaplasma urealyticum (UU) from tracheal aspirates (TA) taken immediately after birth in the development of chronic lung disease of prematurity (CLD), and to analyze the risk factors for CLD according to the preceding illnesses. METHODS: A retrospective cohort study was done in 75 inborn preterm infants admitted to a university hospital NICU and intubated at birth for the respiratory care. TA was taken to measure IL-6 by ELISA and to perform UU PCR. The patients were grouped into four, according to the history of respiratory distress syndrome (RDS) and chorioamnionitis (CA). RESULTS: PCR positive rate of UU was 25.3%. Positive PCR was significantly frequent in the patients with CLD or CA. IL-6 in TA was significantly higher with CLD, CA, or positive PCR. Risk factors for CLD were increased IL-6, positive UU PCR, and PDA in all patients. The risk factors for CLD were PDA in RDS(+)CA(-) group [OR 2.11; 95% CI 1.15-3.89]; PDA [OR 12.0; 95% CI 2.50-57.67] and IL-6 (>284.7 pg/mL) [OR 3.75; 95% CI 1.01-13.90] in RDS(+)CA(+) group; and IL-6 (>284.7 pg/mL) [OR 8.25; 95% CI 1.54-44.14] in RDS(-)CA(+) group. CONCLUSION: PDA was a risk factor for CLD following RDS and increased IL-6 for CLD following CA. Inflammatory response of fetal lung, measured by IL-6 and UU PCR in TA at birth in preterm infants, was associated with CA and might be a risk factor for the development of CLD.

4.Pregnant Women's Knowledge and Compliance about Prevention of Respiratory Infection.
Korean Journal of Nosocomial Infection Control 2013;18(1):7-14
BACKGROUND: Respiratory infection in pregnancy can cause various side effects and affect the fetus. Therefore, efforts to prevent infection during pregnancy are essential. This study investigated knowledge and compliance regarding the prevention of respiratory infection among pregnant women. METHODS: A survey was conducted on May 10, 2012 on 300 pregnant women who attended a maternity school education program in a tertiary care hospital. The responses of 259 women were collected and analyzed. RESULTS: Only 2 women (0.8%) had been educated about respiratory infection prevention methods, while 106 (40.9%) experienced respiratory infection during pregnancy. The mean score of respiratory infection prevention knowledge was 11.63 out of 15 points (percentage of correct answers: 77.5%). The mean score for compliance to respiratory infection prevention was 32.34 out of 52 points (percentage of practice: 62.19%). Knowledge and compliance were found to be positively correlated. CONCLUSION: Although many pregnant women experience respiratory infection during pregnancy, few have opportunities to be educated about prevention. Thus, the positive correlation between knowledge and compliance highlights the need for respiratory infection prevention education programs.

5.Study on the Emergence of Precore Mutant in HBV Infection.
Korean Journal of Clinical Pathology 1997;17(5):858-869
BACKGROUND: The precore mutant hepatits B virus (HBV) cannot produce HBeAg due to the formation of transnational stop codon at nucleotide 1896 of the HBV-DNA precore region. This mutant has been detected worldwide in acute fulminant hepatitis, carrier and chronic HBV infections. It has been controversial whether the emergence of precore mutant HBV is related to the severity of the chronic hepatitis B or not. METHODS: To determine the prevalence and clinical implication of precore mutant infection, 137 HBsAg (+) patients including 12 acute hepatitis, 59 carriers, 41 chronic hepatitis, 15 liver cirrhosis, and 10 hepatomas were examined with mutation site specific assay-polymerase chain reaction (MSSA-PCR). The specificity for the detection of mutant by MSSA-PCR method was confirmed by direct sequencing of PCR products. RESULTS: The precore mutant HBV was detected in 67 of 137 (49%) subjects : none of 12 (0%) acute hepatitis patients, 17 of 59 (29%) carriers, 31 of 41 (76%) chronic hepatitis patients, 12 of IS (80%) liver cirrhosis patients, and 6 of 10 (60%) hepatoma patients. According to the status of serum HBeAg, the emergence rate of precore mutant HBV in HBeAg(-) cases was relatively higher than in HBeAg(+) cases with blood donor and chronic hepatitis. In anti-HBe (+) patients with chronic hepatitis, the precore mutant HBV was found regardless of ALT level in all patients. Emergence rate of precore mutant HBV was abruptly increased after 30 years of age. Among HBV-DNA (-) sera by DNA probe method, the core region of HBV was amplified in 94% of sera by MSSA-PCR method. CONCLUSIONS: The presence of precore mutant HBV may be related to the duration of HBV infections and there seems to be no causal relationship between the presence of precore mutant HBV and the severity of chronic hepatitis.

6.GUIDED BONE REGENERATION OF CRANIAL DEFECTS USING VARIOUS MEMBRANES : AN EXPERIMENTAL STUDY IN RABBITS.
Journal of the Korean Association of Oral and Maxillofacial Surgeons 1997;23(3):474-486
Various techniques for treatment of large bone defects have been reported, instead of using autogenous bone graft. The author have applied and explored for bone repair with polyglactin 910 mesh and fresh fascia late. Full thickness 8x8mm bone defects were made on the frontoparietal bone of rabbits and group 1 defect was covered with polyglactin 910 and group 2 defects with fresh fascia late, but group 3 and 4 were not covered. However the periosteum was left on group 4 but it was not left on group 3. Samples were taken from the operation site for clinical and histological examinations on 2, 4, 8 and 12 weeks after operation, repetitively. The results were as follows ; 1. On the group 1, where ployglactin 910 mesh had been placed, the defects taken in 2, 4 ,8, 12 weeks after operation disclosed osseous regeneration with newly formed bone but the thickness was much less than the original bone. 2. On the group 2, where fresh fascia rata had been placed, the defects taken in 2, 4, 8, 12 weeks after operation disclosed same pattern of group 1. 3. On the group 3 and 4, where membrane had not been placed, the majority of the defects consisted of connective tissue and muscles. 4. On the group 1, resorption of polyglactin 910 mesh was completed after 4 weeks, but on the group 2, the fascial rata still remained intact.

7.Histopathologic Observations on Behcet's Syndrome.
Korean Journal of Dermatology 1981;19(6):853-863
The present study was performed to evaluate clinical manifestations in 26 patients and histopathological findings in 19 patients with Behcets syndrome. 1. Clinical findings: A. Among the 26 patients, 9 were male and 17 were female (male to female ratio was 1: l.9). The age at onset of the disease varied from 10 to 62, with a mean of 26.9. B. The incidence of the major clinical manifestations: The oral ulcers were observed in all of the 26 patients, genital ulcers in 21 patients (81%), cutaneous manifestations in 25 patients (96%) and ocular lesions in 7 patients (27%). C. Saline intradermal test was positive in 62% and PPD intradermal test in 42% 2. Histopathological findings: Fourty-one specimens were taken frorn 19 patients with Behcets syndrome; Erythema nodosum like lesions (15), edematous papules (3), acneiform eruption (1), oral ulcers (4), genital ulcers (8), saline intradermal injection sites (5) and PPD intradermal test sites (5). As a control, 4 specirnens were taken from PPD test sites of the patients with erythem nodosum. The common histopathological findings were perivascular inflammatory cell infiltration, mainly composed of neutrophils and nuclear dusts, and vasculitis of varying degree. A. Cutaneous lesions; In erythema nodosum-like lesions main pathologic foci were in the deep dermis and/or the subcutis, and moderate to severe vasculitis were observed. In edematous papules, however, main foci were in the pa,pill- ary dermis and the upper dermis, papillary dermal edema was prorninent, and vasculitis was rather mild.

8.A Case of Subepodermal Calcifid Nodules.
Korean Journal of Dermatology 1976;14(2):173-178
Subepiderral calcified nodules is a special form of idiopathic calcinosis circumscripta with its distinct clinical and histopathologic features, which was originally described by Winer(1952) as solitary congenital no3ular czlcification of the skin. Although the lesions are usually solitary and congenital, subs aquent investigators reported multiple lesions and later onset. Clinically, th. leions are small hard. yellowish-white warty nodules developed. usually on the face and mostly in children and histopathologically are subepidermal calcified mass with s cvn4ry epidermal changes. Although the pathogenesis is still unexplained, it s seems that the disease is not associated with any systemic or cutaneous disease or any biochemial abnormalities. We present a first recorded case of subepidermal calcified no3ules developed on the left the a Korasn female, aged 23, which has been present for 7 years. Shave biopsy showed typical histopathologic and histochemical features of the subpidermal calcified nodules. Literature were reviewed.
