BACKGROUND: The development and progression of a tumor can be determined by a complex multistep process involving the activation of oncogenes and the inactivation of tumor suppressor genes. The purpose of this study is to investigate the expression of p53, Rb, bcl-2 protein and Ki-67 labeling index in the intrahepatic cholangiocarcinoma. METHODS: We analyzed 36 cases of intrahepatic cholangiocarcinoma obtained by surgical resection. Expression of p53, Rb, bcl-2 proteins and Ki-67 labeling index were evaluated by immunohistochemical study. RESULTS: Expression of p53 protein was detected in 61.1% (22/36) of cholangiocarcinoma. Rb protein loss and overexpression were observed 27.8% (7/36) and 72.2% (29/36) of cholangiocarcinoma. But bcl-2 protein was not expressed. No significant correlation was found between p53, Rb and bcl-2 protein expression and age, sex, gross type, histologic grade, vascular invasion and lymph node metastases. The Ki-67 labeling index was significantly higher in p53 positive group and Rb overexpression group than in p53 negative group (p<0.01) and Rb loss group (p<0.05). There was a positive correlation between p53 protein and Rb protein expressions, but a negative correlation between Rb protein and bcl-2 protein expressions. CONCLUSIONS: The overexpression of p53 protein and Rb protein may be closely associated with cholangiocarcinogenesis, while bcl-2 has a less crucial role in cholangiocarcinogenesis.

BACKGROUND: In congenital heart disease, the lung perfusion through stenosed pulmonary artery is usually decreased. And this decrement of lung perfusion also occurs with diaphragmatic palsy after the operation of congenital heart disease. It is difficult to delineate the amount of lung perfusion in case of combination of pulmonary artery stenosis and diaphragmatic palsy. We examined the change of lung perfusion after the induction of diaphragmatic palsy in rabbits. METHODS: We dissected left phrenic nerves in 20 rabbits to induce left diaphragmatic palsy. The lung perfusion scan was performed with 99mTc-MAA and the movement of diaphragm was examined with fluoroscopy. They were performed as baseline data and on 3rd and 10th day postoperatively. The amount of left lung pefusion before and after diaphragmatic palsy was compared and analysed in 12 rabbits which definitely had diaphragmatic palsy. RESULTS: Weight of the rabbits was 1.65+/-0.26 kg. Left lung perfusion percent was 45.93+/-6.42% before operation and these were 32.48+/-6.09% and 37.62+/-3.39% on the 3rd and 10th postoperative day, respectively. Left lung perfusion was significantly decreased just after diaphragmatic palsy but it was not changed thereafter. The decrement of lung perfusion was not affected by the body weight. The decreased amount of left lung perfusion was reciprocally correlated with the body weight of the rabbits on the postoperative 3rd day but not 10th day. CONCLUSION: Left lung perfusion percent of the rabbits was decreased 7% with the induction of diaphragmatic palsy and the decreased amount was reciprocally correlated with the body weight just after the diaphragmatic palsy was induced.

We experienced a case with benign recurrent hematuria in a 13-year-old boy. He had 5 times of gross hematuria during past four years. There was no abnormal findings on physical examination. He had normal renal function. However the renal biopsy specimen revealed IgA deposits in mesangium under immunofluorescent stain. A brief review of related literatures is also presented.

BACKGROUND/AIMS: Although interferon-a(IFNa) is currently the most effective antiviral agent for treating patients with chronic hepatitis C, its efficacy is not always reliable. Factors suggested to infruence outcome of IFN-a therapy for chronic hepatitis C are histological activity, level of viremia and HCV genotype, etc. The aim of this study was to determine the relationship between several pretreatment factors and response to IFN-a therapy in patients with chronic HCV infection. METHODS: Fifty-four patients with chronic HCV infection(47 with chronic hepatitis and 7 with liver cirrhosis) who received IFN-a(2a or 2b) therapy(3 6 MU, three times a week, for 3 12 months) were included. Level of serum HCV RNA(50 patients), HCV genotype(27 patients) and IgM anti- HCV(21 patients) during pretreatment period were assayed. RESULTS: Overall, 19(35%) subjects achieved sustained response(SR), 12(22%) had transient response(TR) and 23(43%) did not respond (nonresponse;NR). Mean age of patients with SR, TR and NR was 46+ 10, 51+ 7.5 and 54+ 9.7 years, respectively(p<0.05 between SR and NR). Among 30 patients with biopsy-proven chronic hepatitis, 13(43%) achieved SR;but only one(14%) in 7 patients with liver cirrhosis. Mean serum HCV RNA level(X10' copies/ml) was higher in nonresponders(7,7+ 13.0) compared with SR(2.3+ 2. 7) or TR(3.1+ 4.9), although statistically insignificant HCV genotyping in 27 patients revealed type la in 5(18.5%), 1b in 14(52%), 2a in 5(18.5%), 2b in 1(3.7%) and 4 in 2(7%), respectively. In non-1b patients, SR rate was significantly higher than 1b patients(69.2% vs. 21.4%, p=0.03). Although IgM anti-HCV was positive in 12(57%) among 21 patients studied, the positive rate and the titer of IgM anti-HCV was not significantly different in three groups. CONCLUSION: Our results suggest that in patients with chronic hepatitis C, infection with genotype 1b, old age, high serum HCV RNA level and the presence of cirrhosis would predict poor response to IFN therapy.
