N/A Background/Aims: Although the incidence of intrahepatic biliary stone in Korea is relatively high, the pathogenetic role of intrahepatic biliary ]esion on the genesis of intrahepatic stone is not clearly understood yet. This study was perfomed to investigate the patbological changes of intrahepatic bile ducts in hepatolithiasis and compare with other reports, thus get some information about the pathophysiologic role of those lesions. Methods: Patho]ogical and histochemical studies were done on 43 cases of liver resected for the treatment of intrahepatic biliary stones during last 16 years. Results: The highest incidence was at the 6th decade. Male to female ratio was 1:1.4 (18cases to 25 cases) and mean age was 45.4 years. More than half of the cases complained less than 2 months of biliary symptom duration. Majority of the cases(38 cases, 88.3%) revealed stones in the left intrahepatic bile ducts. Histological changes of the intrahepatic bile ducts harboring biliary stones showed superficial epithelial hyperplasia in 20 cases(46.5%), proliferation of intramural glands in 36 (83.7%), extramural glandular hyperplasia in 42(97.7%), pseudopyloric glands in 3(7.0%)and pancreatic acinus in 3 cases(7.0%), and chronic inflammatory reaction in all the cases examined. Mucin in the pseudopyloric glands were mixture of class m mucin and sialo- and sulphomucin. Conclusions: It is concluded that histologic lesions associated with the intrahepatic biliary stones were chronic inflammatory reaction and proliferation of intrahepatic ductal epithelium and peribiliary glands secondary to the inflammation. Hypersecreted glandular secretion of peribiliary glands can be an augumenting factor of the increment of the biliary stones. (Korean J Gastroenterol 1996; 28: 697 - 704)

N/A Background/Aims: Transforming growth factor-g(TGF-g), mutifanctional cytokine, has been suggested to have many actions related to tumor progression and tumor cell behavior, because of its increased expression in cancer cells. Only small number of studies were done for its role in gastric carcinoma, and we have conducted this study to elucidate in depth the role of TGF-/3 in gastric carcinoma progression. Methods: Expression of TGF-/3, epidermal growth factor(EGF), p53 and proliferating cell nuc1ear antigen(PCNA) in gastric carcinoma was studied by immunohi- stochemical method applied to paraffin-embedded tissue sections of endoscopic biopsy materials of 71 cases of gastric carcinoma(24 early and 47 advanced) and imrnunoreactivity of antigens was correlated with histological differentintion of carcinoma, degree of tumor infiltration of mononu- clear cells, serum levels of alphafetoprotein(AFP) and carcinoembryonic antigen(CEA), and pre- sence of distant metastases. Results: TGF-0 in carcinoma tissue was expressed in 31 cases(43.7%) of total 71 cases, and immunopositivity of TGF-0 in advanced gastric carcinoma(AGCj was 55.3%, which was much higher than that(20.8%) of early gastric carcinoma(EGC)(pC0.05). 1here was no significant difference in imrnunopositivity of TGF-0 between different differentiation group. There was negative correlation between expression of TGF-g and degree of tumor infiltration of mono- nuclear cells(p0.05). Immunopositivity of TGF-0 in AGC group was significantly higher in the cases with elevated serum AFP level(82.6%) than that with normal serum AFP leve1(29.1%)(p. 0.05), and also was significantly higher in the cases with elevated serum CEA level(87.6%) than that with normal serum CEA level(40.6%)(pw0.05). There was no correlation between expression of TGF-g and presence of distant metastases or metastatic sites. There was significant positive correlation between expression of TGF-g and EGF(p=0.004), TGF-g and p53(p=0.02) but no correlation between expression of TGF-g and PCNA. Conclusions: Above data indicate that TGF-f3 rnay contributes to gastric carcinoma progression by immunosuppressive action and fibrosis, by growth-stimulatory action via EGF modulation, and that loss of growth-inhibitory effects of TGF-0 on gastric carcinoma, which is related to p53 mutation, may be a critical factor in gastric carcinoma progression.
