This study was to investigate the effects of Gibangganbang on the liver injury induced dimethylnitrosamine, CCl4, ethanol and partial hepatectomy. Hydroxyproline, hepatic fibrosis, hepatic inflammatory cell infiltration, fatty value, lipidoperoxide levels, glutathione levels, mitotic index, contents of protein in the serum and liver tissues were measured and observed. The results obtained were as follows. 1. The increasing level of hydroxyproline volume induced by dimethylnitrosamine in mice was decreased by the oral administration of Gibangganbang. 2. The degree of hitological fibrosis and hepatic inflammatory cell infiltration induced by $CCl_4$ was decreased by the oral administration of Gibangganbang. 3. The degree of fatty value and the increasing level of lipidoperoxide in liver tissues was decreased by the oral administration of Gibangganbang. 4. The level of glutathione in liver tissues was increasing by the oral administration of Gibangganbang. 5. The increasing level of microsomal lipidoperoxide in vitro assay was decreasing by the oral administration of Gibangganbang. 6. The increasing level of the mitotic index, weight of liver, contents of protein, RNA and DNA synthesis of the liver tissues after partial hepatectomy was activated by the oral administration of Gibangganbang. These results suggest that Gibangganbang not only inhibits liver cirrhotic change and ethanol-induced fatty change but also activates antioxidant enzymes and regeneration ability ocf liver.

Objective: This study used cardiac magnetic resonance imaging (MRI) to compare the characteristics of left ventricular remodeling in patients with primary aldosteronism (PA) with those of patients with essential hypertension (EH) and healthy controls (HCs). Materials and Methods: This prospective study enrolled 35 patients with PA, in addition to 35 age- and sex-matched patients with EH, and 35 age- and sex-matched HCs, all of whom underwent comprehensive clinical and cardiac MRI examinations. The analysis of variance was used to detect the differences in the characteristics of left ventricular remodeling among the three groups. Univariable and multivariable linear regression analyses were used to determine the relationships between left ventricular remodeling and the physiological variables. Results: The left ventricular end-diastolic volume index (EDVi) (mean ± standard deviation [SD]: 85.1 ± 13.0 mL/m² for PA, 75.9 ± 14.3 mL/m² for EH, and 77.3 ± 12.8 mL/m² for HC; p = 0.010), left ventricular end-systolic volume index (ESVi) (mean ± SD: 35.2 ± 9.8 mL/m² for PA, 30.7 ± 8.1 mL/m² for EH, and 29.5 ± 7.0 mL/m² for HC; p = 0.013), left ventricular mass index (mean ± SD: 65.8 ± 16.5 g/m² for PA, 56.9 ± 12.1 g/m² for EH, and 44.1 ± 8.9 g/m² for HC; p < 0.001), and native T1 (mean ± SD: 1224 ± 39 ms for PA, 1201 ± 47 ms for EH, and 1200 ± 44 ms for HC; p = 0.041) values were higher in the PA group compared to the EH and HC groups. Multivariable linear regression demonstrated that log (plasma aldosterone-to-renin ratio) was independently correlated with EDVi and ESVi. Plasma aldosterone was independently correlated with native T1. Conclusion: Patients with PA showed a greater degree of ventricular hypertrophy and enlargement, as well as myocardial fibrosis, compared to those with EH. Cardiac MRI T1 mapping can detect left ventricular myocardial fibrosis in patients with PA.

Pachydermodactyly is a rare distinct form of fibromatosis characterized by acquired, asymptomatic dense fibrosis and fibroblastic proliferation around one or more proximal interphalangeal joints. Intralesional triamcinolone injection may be helpful in improving the clinical appearance. A 20-year-old unemployed female patient gave a four years history of progressive swelling of the fingers affecting predominantly the proximal interphalangeal joints of index fingers of left hand and index, middle fingers of right hand. There was no pain and tenderness. Physical examination, complete blood count, antinuclear antibody, rheumatoid factor were unremarkable and radiograph of both hands showed soft tissue swelling only without bony abnormality. We excised the redundant soft tissue from the both sides of proximal interphalangeal joint with longitudinal elliptical fashion. After operation, the fingers of the patient showed marked improvement cosmetically. There were no motor or sensory changes. Pachydermodactyly was first reported in 1996 in Korea. Histologic features include an increased dermal accumulation of collagen and occasionally an increased number of fibroblast. We report for one patient with pachydermodactyly treated with longitudinal elliptical excision and obtained an improvement of clinical appearance.

Purpose Acute pyelonephritis of growing kidneys may result in renal scarring. TGF-${\beta}1$, inflammatory cytokine, has been suggested to play an important role in promoting renal scarring through apoptosis, suppression of cellular proliferation and fibrosis. We observed the effects of a potent anti-inflammatory agent, methylprednisolone on apoptosis and renal scarring in experimentally induced acute pyelonephritic weaning rats. Materials and Methods: To induce ascending pyelonephritis a saline solution containing Escherichia coli type ATCC No. 25922, pili- form (107 bacteria/mL) was infused into the bladder through the 16-guage silicone cannula for 48 hours to 102 three-week-old Sprague-Dawley rats (50-60g). Experimental groups were divided into three groups according to the treatment protocols, group I (ceftriaxone only, n=3l), group II (methylprednisolone+ceftriaxone n=28), control group (n=43) was not treated. Histopathologic scores of inflammatory changes, fibrosis and tubular atrophy, the apoptosis index and TGF-${\beta}1$ expression score were observed at post-infection 1 and 3 week. Datas were analysed using ANOVA test and P value below 0.05 was interpreted as significant. Results: The mortality rate ($21.4\%$) of group II was not different to the control group ($41.9\%$) and group I ($32.3\%$). The inflammatory score of group II ($0.8{\pm}0.87$) at week 1 was significantly lower than those of the control group ($2.3{\pm}0.87$) and Group I ($1.7{\pm}0.79$) (P<0.05). Apoptosis index of group II ($2.9{\pm}2.15$) at week 1 was significantly lower than those of the control group ($10.0{\pm}1.95$) and group 1 ($8.3{\pm}2.53$) (P<0.05). TCF-${\beta}1$ expression score of group II ($0.8{\pm}0.72$) at week 1 was significantly lower than those of the control group ($1.9{\pm}0.68$) and group I ($1.8{\pm}0.60$) (P<0.05). The fibrosis score of group II ($1.1{\pm}1.10$) at week 3 was significantly lower than that of the group I ($1.8{\pm}0.83$) (P<0.05) Conclusion: Conclusion Combined treatment with methylprednisolone and ceftriaxone reduced inflammation, fibrosis, apoptosis and TGF-${\beta}1$ expression in acute pyelonephritic weaning rats, compared to ceftriaxone alone. Anti-inflammatory agent supplemented to antibiotics could prevent renal scarring more effectively. (J Korean Soc Pediatr Nephrol 2002 ; 6 : 75-84)

Background : An excessive accumulation of neutrophils in lung tissue has been known to play an important role in mediating the tissue injury among the adult respiratory distress syndrome, idiopathic pulmonary fibrosis and cystic fibrosis by releasing toxic oxygen radicals and proteolytic enzymes. Therefore, it is important to understand a possible mechanism of neutrophil accumulation in lung tissue. In many species, exposure to hyperoxic stimuli can cause changes of lung tissues very similar to human adult respiratory distress syndrome and neutrophils are also functioning as the main effector cells in hyperoxic lung injury. The purpose of the present study was to examine whether neutrophils function as a key effector cell and to study the nature of possible neutrophil chemotactic factors found in bronchoalveolar lavage fluid from the hyperoxia exposed rats. Methods : We exposed the rats to the more than 95% oxygen for 24, 48, 60 arid 72 hours and bronchoalveolar lavage(BAL) was performed. Neutrophil chemotactic activity was measured from the BAT- fluid of each experimental groups. We also evaluated the molecular weight of neutrophil chemotactic tractors using fast performance liquid chromatography and characterized the substances by dialyzer membrane and heat treatment. Results : 1) The neutrophil proportions in bronchoalveolar lavage fluid began to rise from 48 hours after oxygen exposure, and continued to be significantly increased with exposure times. 2) chemotactic index for neutrophils in lung lavages from rats exposed to hyperoxia was significantly higher in 48 hours group than in control group, and was significantly increased with exposure time. 3) No deaths occured until after 48 hours of exposure. However, mortality rates were increased to 33.3 % in 60 hours group and 81.3 % in 72 fours group. 4) Gel filtration using fast performance liquid chromatography disclosed two peaks of neutrophil chemotactic activity in molecular weight of 104,000 and 12,000 daltons. 5) Chemotactic indices of bronchoalveolar lavage fluid were significantly deceased when bronchoalveolar lavage fluid was treated with heat ($56^{\circ}C$ for 30 min or $100^{\circ}C$ for 10 min) or dialyzed (dialyzer membrane molecular weight cut off : 12,000 daltons). Conclusion : These results suggested that the generation of neutrophil chemotactic factor and subsequent neutrophil influx into the lungs are playing an important roles in hyperoxia-induced acute lung injury. Neutrophil chemotactic factor in the lung lavage fluids consisted of several distinct components having different molecular weight and different physical characteristics.

Purpose: Non-alcoholic fatty liver disease (NAFLD) in children has become an important public health issue because of its high prevalence and severity. Several noninvasive methods for estimating NAFLD are under investigation. We aimed to evaluate the usefulness of serum ferritin as a biomarker of severity of pediatric NAFLD patients. Methods: A total of 64 NAFLD patient were enrolled from Severance Children's Hospital from March 2010 to February 2013. Serum ferritin levels, liver related laboratory tests, liver magnetic resonance imaging (MRI) (2-dimensional [2D] proton density-fat fraction) and NAFLD severity markers were compared between obese group and overweight group. Correlation analyses were performed between serum ferritin and laboratory values including NAFLD severity markers. Results: In obese group, serum ferritin, alanine aminotransferase (ALT), total bilirubin, international normalized ratio (INR), MRI 2D proton density-fat fraction, aspartate aminotransferase (AST) to platelet ratio index (APRI) and fibrosis- 4 (FIB-4) (an index score calculated from platelet count, ALT, AST and age) were significantly higher than those of overweight group. NAFLD severity markers, APRI and FIB-4, and liver specific important laboratory values, AST, ALT, INR, cholesterol, triglyceride and low density lipoprotein show significant correlation with serum ferritin in NAFLD patients. Conclusion: Serum ferritin concentrations could be a candidate of useful severity marker in the pediatric NAFLD patients.

Purpose: It has been reported that children with hypopituitarism have features of metabolic syndrome, including obesity, impaired glucose tolerance, and dyslipidemia. The aim of this study was to investigate the clinical features and liver histology of pediatric non-alcoholic fatty liver disease (NAFLD) associated with hypopituitarism. Methods: We reviewed the clinical data of 11 children diagnosed with NAFLD among patients with hypopituitarism. Results: The mean age at the time of diagnosis of hypopituitarism was 10.4${\pm}$3.2 years, and the mean age at the time of diagnosis of NAFLD was 13.1${\pm}$2.7 years. A craniopharyngioma was the most common cause of pituitary dysfunction. At the time of diagnosis of NAFLD, 9 patients (82%) had a body mass index greater than the 85th percentile, 5 patients (45%) had elevated fasting blood glucose levels, and 9 patients (82%) had hypertriglyceridemia. The mean height SD score was significantly lower at the time of diagnosis of NAFLD than at the time of diagnosis of hypopituitarism. Of the six patients who were biopsied, one had cirrhosis, two had non-alcoholic steatohepatitis (NASH) with bridging fibrosis, two had NASH with mild portal fibrosis, and one had simple steatosis. Conclusion: Children with hypopituitarism are at risk of short stature, obesity, dyslipidemia, and NAFLD. The early diagnosis of NAFLD is important in children with hypopituitarism because advanced fibrosis is common.
