Purpose: Mycoplasma pneumoniae infection is relatively common in childhood. Its extrapulmonary manifestations have been reported so much, but hepatitis associated with it has not been studied yet until now in Korea. Methods: We performed the prospective study of 19 cases that had AST and ALT>50 IU/L respectively without evidence of hepatitis A, B, C, cytomegalovirus, and Ebstein-Barr virus infections amongst 143 patients with M. pneumoniae pneumonia who were admitted to the Department of Pediatrics, Seoul Red Cross Hospital from Jan. 1999 to Dec. 2000. Results: 1) Hepatitis occurred in 13.3% of Mycoplasma pneumoniae infection, especially in fall and winter times. The average age was 4.86 years and male to female ratio was 2.2:1. 2) Vomiting was developed in 21.1%, diarrhea in 36.8%, and hepatomegaly in 21.1%, respectively. And leukocytosis was noted in 21.1%, eosinophilia in 15.4%, anemia in 10.5%, and thrombocytosis in 5.3%, respectively. The average level of C-reactive protein was $6.34{\pm}4.82$ mg/dl. 3) There was no hyperbilirubinemia, but hypoalbuminemia was detected in 42.1%. The average serum levels of AST and ALT were $214.05{\pm}183.22$ IU/L and $284.16{\pm}286.84$ IU/L, respectively. 4) Chest radiology showed lobar or lobular consolidation in 73.7%, bronchial infiltration in 26.3%, and pleural effusion in 31.6%. 5) The average length of hospitalization was 7.9 days, and the average length of normalization of serum transaminases was 8.8 days. All patients recovered within 2 weeks completely. Conclusion: The prognosis of M. pneumoniae hepatitis is good. However, its incidence is not so low that liver function should be considerately checked in case of M. pneumoniae infection.
Purpose: The prognosis of neonates with cholestasis is not clear. Some factors, such as high peak bilirubin levels and liver histologic findings have been claimed to affect the prognosis adversely. Our study aims to define which factors influence the prognosis of neonatal intrahepatic cholestasis. Methods: Retrospective reviews of the medical records were performed in 32 cases with neonatal intrahepatic cholestasis, who were admitted to Department of Pediatrics, Pusan National University Hospital from July 1995 to July 2002. Neonates were classified into 2 groups according to the duration of elevated serum alanine aminotransferase (ALT) levels more or less than 6 months. The data, such as biochemical, histopathologic and radiologic findings, were compared in both groups. Biochemical data included mean peak level of serum ALT, total bilirubin, direct bilirubin, and alkaline phosphatase. Histologic parameters related to lobular architecture, fibrosis, inflammatory infiltration and degenerative features of hepatocytes were arbitrary estimated on a scale of 1 to 3. Results: There were 19 males and 13 females, whose mean age was 48 days (14~77 days). The peak serum ALT levels were higher in the poor outcome group. Ductular proliferation and portoportal bridging were more severe in the poor outcome group. But the degree of multinucleated hepatocytes, hepatocellular swelling and canalicular plug did not appear to be significantly related to the long-term outcome. The DISIDA scintigraphy by visualization time of gall bladder and intestine was not useful in predicting outcome of neonatal intrahepatic cholestasis. Conclusion: Neonates who have intrahepatic cholestasis with high serum ALT levels, severe ductular proliferation and portoportal bridging in the liver biopsy specimen should be carefully followed up because they may have a poor prognosis.

Atopic dermatitis is a chronic, relapsing inflammatory skin disease. This study aimed to investigate the therapeutic benefits of Aronia melanocarpa (AM) and Moringa oleifera seed extract (MO) on experimental atopic dermatitis. We examined the effects of AM or MO and their combination on 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis in BALB/c mice as well as tumor necrosis factor $(TNF)-{\alpha}$ and interferon $(IFN)-{\gamma}-stimulated$ HaCaT keratinocytes. Mice were orally treated with extract during repeated application of DNCB to shaved dorsal skin. Our results show that treatment with AM and MO in combination reduced histological manifestations such as epidermal hyperplasia and inflammatory cell infiltration. Furthermore, it significantly decreased skin thickness and serum immunoglobulin E (IgE) level compared to the AM or MO alone treated group. Combined extract of AM and MO suppressed expression of $TNF-{\alpha}/IFN-{\gamma}-induced$ T helper 2 (Th2) chemokines such as thymus and activation-regulated chemokine and macrophage-derived chemokine. To sum up, combination of AM and MO suppressed the inflammatory response and serum IgE as an indicator of several allergic diseases in DNCB-induced experimental atopic dermatitis and Th2 chemokine expression in HaCaT cells. This result suggests that combination of AM and MO could be a valuable strategy to improve atopic dermatitis.
Background: Ischemia reperfusion injury is known to contribute to the major causes of the early graft failure in lung transplantation. Triiodothyronine (T3) has been suggested to ameliorate ischemia reperfusion injury from both in vivo and in vitro experiments of various organs. Prospecting its beneficial effect for pulmonary allograft preservation, we made a new solution by adding T3 into the extracellular type dextran solution. Material and Method: Twelve adult mongrel dogs underwent left lung allotransplantation. Six donor dogs were flushed with the new solution(Group 1, n=6), and the remaining six were flushed with Euro-Collins solution to serve as controls(Group 2, n=6). Allografts were stored in each preservation solution for 20 hours at 4$^{\circ}C$. Left single lung transplantations were performed. The right pulmonary artery and the right main bronchus were clamped at 15 minutes after the reperfusion and maintained throughout the experiment to evaluate the transplanted left lung function. Result: Arterial carbon dioxide tension was better in group 1 than in group 2 throughout the experiment period and the difference was statistically significant at 2 hours after reperfusion(28.0${\pm}$3.0 mmHg and 53.1${\pm}$17.4 mmHg, p<0.05). The differences of arterial oxygen partial pressure, peak airway pressure and pulmonary vascular resistance showed no statistical significance. The malondialdehyde(MDA) level, measured from tissue obtained at 120 minutes after reperfusion showed no statistically significant difference. The tissue wet/dry ratio of group 1(649${\pm}$27 %) was significantly lower than that of group 2(686${\pm}$71 %, p<0.05). The microscopic examination revealed varying degrees of injury represented mainly by findings such as perivascular neutrophil infiltration, capillary hemorrhage and interstitial congestion. These findings were less severe in group 1 than those in group 2. Conclusion: The new solution demonstrated superior allograft preservation after 20 hour ischemia compared to Euro-Collins solution in canine single left lung transplantation model, these results suggest that T3 might be a promising agent for pulmonary allograft preservation.
Tooth movement, the phenomena and mechanisms of which are still controversial, can be considered as part of the result of the inflammatory processes. The purpose of this study was to examine the activity of macrophage and T-cell, playing important roles in the immune reaction, in the periodontal ligament of dog, in which experimental tooth movement was performed. Six one and half year-old dogs, a control and 5 experimentals, were studied. Light force (50-75g) was applied by placing open-coil spring between left mandibular premolars ; heavy force (250-300g), between right mandibular premolars. Experimental dogs were sacrificed at 12 hours, 1, 3, 7 and 14 days since force application, respectively. And the histologic and the immunohistochemical evaluation on the obtained tissue were performed, using $\alpha$-1-antichymotrypsin and CD3 antibodies. The results were as follows : 1. There were more inflammatory cell infiltrations in heavy force group than in light force group until 3 days. But from 7 dsays on, no difference was not observed between groups ; Such an infiltration was more evident at pressure side than at tension side. 2. Osteoclastic activity at pressure side began to be seen in 12 hours, increasing until 7 days. After then it decreased ; Such an activity was more evident in heavy force group than in light force group. 3. Tearing of periodontal ligament and vascular dilatation at tension side began to be seen in 12 hours, increasing until 3 days. After then it decreased ; Such an observation was more evident in heavy force group than in light force group, but there was no difference between groups in 14 days. 4. $\alpha$-1-antichymotrypsin expression in control group was positive, mainly in sulcular epithelium, but negative in periodontal membrane, pulp, bone cells. 5. $\alpha$-1-antichymotrypsin expression in experimental group was more positive in pressure side than in tension side ; The expression was a little more positive in cervical area of tooth until 3 days, but after 7days, it was more positive in apical area. 6. $\alpha$-1-antichymotrypsin expression in light force group began to be observed in 12 hours and reached to the greatest level in 7 days, after which it decreased ; In heavy force group, it was the greatest in 3 days, after which it decreased. 3 Expression in the periodontium was almost negative.

Background: The incidence of mycoplasmal pneumonia is predominantly at childhood and early adulthood, but in adults, its incidence is low and its symptoms and physical findings are nonspecific. The definite diagnosis of M. pneumoniae pneumonia can be made by sputum culture, but requires several weeks for positive results, and the early diagnosis must initially be based on the serologic tests and appropriate clinical findings. Thus, we evaluated the clinical aspects of M. pneumoniae pneumonia in the adults patients. Method: Among the admitted patients due to pneumonia, the definite diagnosis is anti-M. pneumoniae antibody titer of $\geq$ 1:40 and a single cold agglutinin titer of $\geq$ 1:64. The presumptive diagnosis is anti-M. pneumoniae antibody titer of $\geq$ 1:40 or a single cold agglutinin titer of $\geq$ 1:64 and the clinical characteristics or chest X-ray findings are compatible with M. pneumoniae pneumonia. We studied the age and sex distribution, seasonal distribution, clinical symptoms, physical findings, serologic test, chest X-ray findings, treatment and its progression. Results: 1) The age distribution was even and the ratio of male to female was 1:1. 2) The monthly distribution was most common in January(16.7%) and the seasonal distribution in autumn and winter(autumn: 30%, winter: 33.3%). 3) The cold agglutinin titers were higher than 1:64 in 12 cases(40%), and reached the peak level around 2 weeks from onset and antimycoplasma antibody titers were higher than 1:160 in 5 cases(16.7%). 4) On the chest X-ray, pulmonary infiltration was noted in 28 cases(93.3%) among 30 cases and right lower lobe involvement was the most common(33.3%) and both lower lobe involvement was noted in 7 cases(23.3%). 5) The mean treatment duration was most common(33.3%) in 1 week to 2 weeks after admission and 26 cases(86.7%) were improved within 4 weeks. 6) On admission, there was fever(${\geq}38.9^{\circ}C$) in 17 cases(56.7%), and the fever subsided in 12 cases(70%) within 3 days after treatment using erythromycin. Conclusion: The mycoplasmal pneumonia in adults shows milder clinical patterns than that in childhood and can be completely recovered without complication by early diagnosis and treatment.

Purpose : Asthma is characterized by the presence of airway hyperresponsiveness(AHR) and inflammation. The extensive eosinophil infiltration into the lung is the hallmark of asthma and contributes to the damage of respiratory epithelium during late phase airway responses. Eotaxin is the major eosinophil chemoattractant found in bronchoalveolar lavage(BAL) fluid of allergic inflammation. IL-13 has been known to induce the expression of exotaxin and eosinophilia. IL-13 also induces airway inflammation, mucus production and leads to marked fibrosis, airway remodeling and AHR. We investigated whether serum IL-13 levels can reflect the presence of airway hyperresponsiveness in children with asthma, and the relationship between serum IL-13 and eotaxin levels. Methods : Using sandwich enzyme-linked immunosorbent assay, the serum IL-13 and eotaxin levels were measured in 13 atopic asthmatics, 5 atopic non-asthmatics and 12 control subjects. Metacholine challenge tests were performed in all subjects. Airway hyperresponsiveness to metacholine was expressed as provocative concentration of metacholine causing a 20% fall in FEV1[$PC_{20}mg/mL$]. $PC_{20}$ value of 25 mg/mL was used as a cut-off for defining a AHR. Results : Serum IL-13 levels showed positive correlation with eotaxin levels. Serum IL-13 and eotaxin levels showed no differences among atopic asthmatics, atopic non-asthmatics and control subjects. And there were no differences serum IL-13 and eotaxin levels in children with and without AHR and atopy. Serum IL-13 and eotaxin levels did not correlate with $logPC_{20}$ levels. Conclusion : IL-13 is closely related to the eotaxin release. But serum IL-13 and eotaxin per se can't predict the severity of airway hyperresponsiveness. IL-13 and eotaxin may have local effect on respiratory epithelium or there can be some factors to induce airway hyperresponsiveness other than serum IL-13 in asthmatic airways.

Purpose : This study was designed and performed for evaluations of clinical manifestation and course of the children under 2 year of age with respiratory tract infection and positive respiratory syncytial virus(RSV) antigen. Methods : The selection criteria of the patients were children under 24 month-of-age, Clinical manifestation of respiratory tract infection, and positive RSV antigen that was detected by Vitek ImmunoDiagnostic Assay System(VIDAS) from nasal cavity. The additional laboratory and simple chest X-ray findings were reviewed from the chart of children who were admitted Wonkwang university hospital from October 1999 to March 2000. Results : Total number of patients enrolled on this study was 102. The 48(47%) children were RSV antigen positive by VIDAS method. Abnormal chest X-ray findings were noticed in 38 cases. The male to female sex ratio of 48 RSV antigen positive cases was 1.2 : 1. The mean and range of age was $10.2{\pm}5.9$ and 1.0~24 months. The peak outbreak of cases was noticed on November, 1999. All of the cases shows coughing but rale was audible in 30 cases(60%). Dyspnea, wheezing, and intercostal retraction were noticed 11(23%), 15(31%), and 10(21%) cases respectively. The most common chest X-ray finding was scattered patch infiltration that was noticed in 30 cases(63%). The mean total white blood cell counts in peripheral blood was $12,608{\pm}4,686/mm^3$. The mean blood level of IgA and IgE were $50.8{\pm}20.9$ and $72.1{\pm}98.3mg/dL$ respectively. The C-reactive protein was $16.0{\pm}18.5mg/L$. Total 5 cases need a mechanical respiraton. The duration of admission was under 7 days in 36 cases(75%). Conclusion : The RSV antigen was detected commonly in late fall and winter season. The severity of children under 2 years old with RSV respiratory tract infection take in some degree a gave courses.
Background : To evaluate the efficacy of two methods of obtaining lung recruitment to reduce ventilator-induced lung injury(VILI). Methods : Fifteen New-Zealand white rabbits were ventilated in the pressure-controlled mode while maintaining constant tidal volume(10 ml/kg) and fixed respiration rate. Lung injury was induced by repeated saline lavage (PaO2<100 mmHg), and the pressure-volume curve was drawn to obtain Pflex. The animals were then randomly assigned to three groups and ventilated for 4 hours. In the control group(n=5), positive end-expiratory pressure(PEEP) less than that of Pflex by 3 mmHg was applied throughout the study. In the recruitment maneuver(RM) group(n=5), RM(CPAP of 22.5 mmHg, for 45 seconds) was performed every 15 minutes in addition to PEEP level less than Pflex by 3 mmHg This phrase is unclear. In the Pflex group, PEEP of Pflex was given without RM. Gas exchange, lung mechanics, and hemodynamics parameters as well as pathology were examined. Results : 1) Both the control and RM groups showed decreasing tendency in PaO2 with time. There was significantly decreased PaO2 at 4 hr compared to Ihr(p<0.05). But in the Pflex group, PaO2 did not decrease with time(p<0.05 vs other groups at 3, 4 hr). PaCO2 did not show significant difference among the three groups. 2) There was no significant difference in static compliance and plateau pressure. Mean blood pressure and heart rate also did not show any significant difference among the three groups. 3) The pathologic exam showed significantly less neutrophil infiltration in the Pflex group than in the control group(p<0.05). There was borderline significant difference in hyaline membrane score among the groups (p= 0.0532). Conclusion : Although recruitment maneuver of the injured lung may be important in decreasing VILI, it alone may not be sufficient to minimize VILI.

We investigated whether or not Schisandra chinensis (SC), a traditional herbal medicine, has protective effects against alcohol-induced fatty liver and blood alcohol clearance. Two tests focused on acute intoxication and chronic ethanol treatment were carried out. For the chronic ethanol treatment test, rats were fed ethanol by intragastric administration everyday for 8 weeks to induce alcoholic fatty liver. Ethanol treatment significantly increased blood alcohol concentration at 90 min after acute ethanol intoxication. Compared with the two ethanol-treated groups, rats administered ethanol along with SC extracts showed an approximately 13% increased blood alcohol clearance rate at 360 min. Chronic ethanol treatment significantly increased serum and hepatic triglyceride (TG) levels, and caused fatty degeneration of liver. Ethanol treatment also elevated the serum total-cholesterol (TC) level. However, after feeding of ethanol plus SC extracts, ethanol-induced elevation of hepatic TG levels reversed, whereas elevation of serum TG and TC levels was not observed after treatment with SC extracts. Ethanol treatment significantly increased ${\gamma}$-GT, aspartate aminotransferase, and alanine aminotransferase activities after 8 weeks. Compared with the ethanol-fed group, rats administered ethanol plus SC extracts for 4 weeks showed attenuated fatty degeneration as well as decreased hepatic function test values. SC administration also significantly increased intracellular lipid accumulation in hepatocytes and reduced steatosis score and hepatic TG levels, as measured by biochemical and histolopathological analyses. Our results indicate that the protective effects of SC are accompanied by a significant decrease in hepatic TG levels, thereby suggesting SC has the ability to prevent ethanol-induced fatty liver, by reducing hepatic TG and enzyme levels in alcoholic rats.
