For sequential phenotypic changes including enzyme altered hepatocytic foci, hyperplastic nodules, hepatocellular adenomas and carcinomas were produced in Sprague-Dawley rats by Solt-Farber method (administration of diethylnitrosamine and acetylaminofluorene (AAF), and partial hepatectomy). The immunohistochemical expressions of glutathione S transferase P (GST-P) and bromodeoxyuridine (BrdU) were assessed for selective proliferative activity in the enzyme altered foci and the subsequently developed lesions by double immunohistochemical staining technique. Immunoreactive areas against GSTP gradually increase from early period of carciogenesis. BrdU labeling in such areas remained high during the first week. but decreased thereafter. BrdU labeling index remained low in the GSTP negative area throughout the experimental period. This suggests that cells in the enzyme altered foci keep away from the suppressor effect of AAF in contrast to the normal cells in which their growth are inhibited by AAF. BrdU labeling index remained very low in both hyperplastic nodule and adenoma which were prevalent during the mid-experimental period, but increase markedly in carcinoma. The long period of low BrdU labeling index seems to correspond to the "slowly growing step of persistent nodule" during hepatocarcinogenesis. The differentiation index, a ratio of S phase fraction between GSTP positive and negative areas, was low in adenoma-developing period and high in carcinoma-developing period. C-Ha-ras p21 was not expressed in foci of enzyme altered hepatocyte and hyperplasia, but highly positive in carcinoma. This indicates that the c-Ha-ras may involve the late step of hepatocarcinogenesis.

Gastric lesion in familial polyposis coli is commonly presented with fundic gland hyperplastic polyps, but duodenal and gastric adenomas together with their carcinomatous transformation have been rarely described in familial polyposis coli mostly by case reports. We present three cases of gastric adenomas in familial polyposis coli with one in synchronous development of gastric adenocarcinoma in Korea. All three cases had the family history related to familial polyosis coli and received proctocolectomy because of synchronous development of colonic adenocarcinoma. One patient developed gastric polyposis and adenocarcinoma 8 years after colectomy, and the remaining two presented with multiple polyps either in the stomach or duodenum synchronously at the time of the diagnosis of familial polyposis coli with colonic adenocarcinoma. None disclosed any evidence of Gardner's syndrome. We conclude that association of gastric adenomas in familial oplyposis coli is not uncommon and gastric adenoma-carcinoma sequence is an another important participating mechanism to understand the histogenesis of gastric carcinoma in Korea.

Authors' presented an interesting case, 19 years old boy, who was been suffered from retinal periphlebitis of both eyes which thought to be induced by Barre Syndrome. This patient also has pulmonary tuberculosis and visual symptoms of Barre Syndrome in this case were ocular pain and visual disturbance that appeared and disappeared suddenly due probably to irritation of the ventral nerve roots (C5 to T1) with also irritation of sympathetic fibers contained in them.

Reviewing the results of the blood cultures performed at Yeungnam University Hospital during 4-year-period through January, 1, 1984 to December 31, 1987, the following results were obtained. 1) Out of 8083 blood specimens cultured microorganisms grew in 582 specimens with positivity rate of 7.20%. Polymicrobial bacteremia was found in 16 patients. 2) Among 582 positive specimens, Gram-positive cocci grew in 189 specimens, and Gram-negative bacilli, in 393 specimens. Clinically significant microorganisms consisted of 82 Staphylococcus aureus, and 20 Streptococcus species in Gram-positive cocci group, 80 Salmonella typhi, 72 Escherichia coli, 72 Salmonella paratyphi A in Enterobacteriaceae, and 46 Pseudomonas cepacia, and 16 Pseudomonas aeruginosa in glucose non-fermenting microorganisms. 3) Increasing incidence of Serratia, Acinetobacter and Pseudomonas species as major nosocomial infection source is noteworthy. They showed increased tendency from 6.3% of 1984 to 17.7% of 1987 of total positive blood cultures. 4) High isolation rate of Pseudomonas species and Aeromonas hydrophila was noted in summer, while Salmonella typhi showed high prevalence from May to September and in January. 5) In susceptibility tests of isolated organisms, staphylococcus aureus was sensitive to basic antimicrobial agents except for ampicillin. The glucose non-fermenting microorganisms showed high resistance to basic antimicrobial agents in 32.2%. In conclusion, considering the relatively higher incidence of growth of Staphylococcus epidermidis than ideal level indicates that sampling technique should be improved. Secondly, all the hospital staffs in cooperation with Hospital Infection Committee are desirable to pay efforts to decrease the nosocomial infection.
