OBJECTIVE: Adult onset Still s disease is an acute systemic inflammatory disorder. There are no pathognomonic symptoms or specific laboratory abnormalities. In recent reports, serum ferritin concentration is increased in active disease phase and decreased after defervescence. Our purpose was to determine the clinical significance of serum ferritin as an indicator for disease activity. METHODS: Seven patients who were diagnosed as adult onset Still s disease at Samsung Medical Center between October 1994 and March 1997, were reviewed. In these patients we checked leukocyte count, ESR, CRP and serum ferritin concentrations at the time of diagnosis and during follow-up periods and recorded febrile events during follow-up periods. RESULTS: At the time of diagnosis and during febrile periods, the concentrations of ferritin were extremely high(927ng/ml to 96,650ng/ml normal 10-290.8 ng/ml). The values were unrelated to other manifestations of the disease or laboratory findings. The ferritin concentrations decreased rapidly after adequate treatment. Eleven febrile reattacks happened in 7 patients. Serum ferritin concentrations were increased in 8 febrile attacks, while leukocyte count, ESR, and CRP were increased in 5, 5, 6 febrile attacks respectively, There were 10 events of increased serum ferritin concentrations in 7 patients during follow-up periods and 8 events were related with fever. The increases of other laboratory tests were similar. CONCLUSIONS: In all patients, serum ferritin concentrations were increased at the time of diagnosis and closely related to fever. During follow-up periods, serum ferritin concentrations are helpful in monitoring disease activity and guiding decisions about treatment.

Intraductal variant of peripheral cholangiocarcinoma is extremely rare. This variant shows intraductal growth and intraluminal extension without any infiltrative growth. The mode of intraductal growth is not known. The prognosis of this variant is better than that of usual cholangiocarcinoma. We report three cases, one of which is associated with Clonorchis sinensis (CS) infection. The tumors were entirely confined within the dilated peripheral tributaries of the intrahepatic bile duct. Microscopically, the tumors were well to moderately well differentiated, with a papillary or a micropapillary growth pattern. Focal clear cytoplasmic change and mucin production were noted. The tumors showed intraductal spreading without any invasion to the liver parenchyme. Mucosal hyperplasia and dysplasia were noted in the adjacent ducts. The authors assume that intraductal cholangiocarcinoma is a distinct subtype, and persistent irritation, such as, CS infection may undergo a malignant transformation through mucosal dysplasia.

Pleomorphic adenoma presenting as primary lesion of the bronchus is very rarely encountered, and in our knowledge only 6 cases have been reported in the literature of the western world, and no case report has been published in Korea. Currently, we experienced a case of bronchial pleomorphic adenoma occuring in a 38 years old woman. On X-ray examination, hazy density in the right upper lobe and emphysematous change in the right lower lobe were noted. A right pneumonectomy was done under bronchoscopic diagnosis of bronchial adeoma. The pathologic examination of the present case showed a polypoid endobronchial tumor, 1.4 x 1.1 cm (with extraluminal portion, 2.2 x 1.7 cm) in the right upper bronchus. The microscopic examination revealed a pleomorphic adenoma showing same morphology as those found in the salivary gland. This case, therefore, was believed to be a genuine example of bronchial pleomorphic adenoma of salivary gland type. We compared this case with 6 cases in the literature.

The purpose of this study is to evaluate the flow ability of the thermoplasticized Gutta Percha in different temperatures. Four Gutta Percha products were classified by its hardness (soft, medium, and hard) and were experimented by the Rheometer (Melt flow indexer MFI-10, DAVENPORT, England) measuring apparatus, in (23 ± 2) ℃, and in a relative humidity of (50 ± 5) %, following the guidelines of ISO 1133-1:2011. The heating temperature ranged from 108℃, 160℃ to 200℃, and the load at 2.16 kg and 3.8 kg. The Gutta Percha was cut in 5 mm to be suitable for the rheometer pressurization process. After the experiment was conducted with a preheating time of 5 minutes, a cutting time of 5–240 seconds, and a sample of 10 grams, the Gutta Percha did not show any changes in fluidity for 108℃, 160℃, but showed a change in its flow ability in 200℃. Also, the Gutta Percha did not show any changes in its fluidity when it was pressurized by 2.16 and 3.8 kilograms. Therefore, this experiment shows that the heating temperature and the cut-off time showed a significance while measuring the melt flow rate.

BACKGROUND AND OBJECTIVES: Cardiac troponin T (cTnT) has been used as a very sensitive marker of cardiac injury caused by ischaemia, myocarditis, and cardiomyopathy. After cardiac injury, the fetal cTnT isoform expression in the heart and serum cTnT increases. To investigate the increased levels of serum cTnT, and the expression of fetal cTnT isoform in the heart, that can predict myocardial injury, we measured serum cTnT levels and the fetal cTnT isoform expression at various time points during the early phase of myocardial toxicity induced by adriamycin (ADR) in rat. MATERIALS AND METHODS: Male Sprague-Dawley rats were injected, intraperitoneally, with ADR (5 mg/kg) twice a week for 2 weeks. Control rats were injected with saline. Serum cTnT levels were measured by ELISA. The ratio of fetal/adult (F/A) cTnT isoform expression (%) was semi-quantified by RT-PCR using total RNA from frozen hearts. RESULTS: Serum cTnT levels did not increase by 1 week after ADR injection, but increased significantly after 2 weeks. The ratio of F/A cTnT in the heart significantly increased from day 1, peaked at 1 week and persisted until the end of 2 week. CONCLUSION: The expression of the fetal cTnT isoform occurred from 1 day after ADR injection when the serum cTnT levels were still normal. Although the serum cTnT level is a very sensitive, and an early marker, of cardiac damages, the fetal cTnT isoform expression in the endomyocardial biopsy specimen may be a more sensitive and an earlier marker in the ADR-induced myocardial damage.

PURPOSE: We compared body growth, blood cell counts, and chemistry among infants receiving soy-based formula (SF), breast milk (BM), and casein-based formula (CF). METHODS: Full-term neonates delivered at our hospital from June 2001 to August 2003 were recruited and divided into 3 feeding groups (BM=20, SF=19, CF=12) according to the parents wishes. Breast feeding or artificial formulae were given during the initial 3 months of age; thereafter, weaning foods were added freely. Height, weight, head circumference, skin-fold thickness, and mid-arm circumference were measured at birth and 1, 2, 4, 5, 12, and 36 months of age. Cell counts and blood chemistry were analyzed at 5, 12, and 36 months of age. RESULT: At 5 months of age, body weight was the lowest in the SF group; the height was similar among all groups. Thereafter, there were no differences in height or weight among the groups until 36 months of age. Hemoglobin was the lowest in the BM group at 5 and 12 months of age (P<0.05). At 5 months of age, serum cholesterol, BUN, phosphates, and K+ were significantly lower in the SF group; thereafter, all chemical parameters were similar until 36 months of age. CONCLUSION: Infants fed with SF showed normal growth during the first 3 years of life as compared to infants fed with BM and CF. Low values of serum phosphates and K+ at 5 months of age in the SF group, despite the high mineral content, suggest that further investigation is needed for effective mineral absorption.
