Primary phycomycosis of the stomach within the ulcerative portion of early gastric carcinoma is presented in a sixty one year old male alcoholics. In the center of IIc type submucosal adenocarcinoma was a large deep ulcer (UL-IV) which was the only seat of phycomycetes infection accompanied with angioinvasion and exudative endovasculitis aside from unusual granuloma formation with Splendore Hoeppli phenomenon and eosinophilic response as in allergic granulomatous aspergillosis. The above features were reconstructed to indicate that the phycomycetes infection was confined to the type III area of IIc + III early gastric carcinoma, and that the local ulcerogenic lesion seems more contributory in its development than systemic factors including gastric carcinoma per se or alcoholic consumption.

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.

This study was attempted to know that the interactions of various fungi, and methionine and MgSO4 introduced as the substrate of culture media for fungi were affected to produce aflatoxins by Asp. flavus. 5 different fungi were isolated from the fermented soybean mash and were cultured in Chemically Defined medium (C.D. media) and soybean mash at 25 degrees for 10 days. (1) It was confirmed that Asp. flavus produced aflatoxins in the C.D. medium and soybean mash, but that Asp. niger, Asp. oryzae, Asp. awamori and Asp. terreus did not produced them respectively. (2) Asp. flavus cultured with Asp. niger did not produce aflatoxins in C.D. medium, but produced in soybean mash, in other hand, Asp. flavus with other fungi except Asp. niger produced aflatoxins in C.D. medium and soybean mash. (3) The growth of fungi were more prosperous in the separate culture than in the mixed culture. (4) In the C.D. medium added 20% of cultured medium of Asp. niger, Asp. flavus did not produce aflatoxins but other cultured medium did not prohibit the production of aflatoxins by Asp. flavus. (5) On the contrary, MgSO4 increasing the productivity of aflatoxins by Asp. flavus in the C.D. medium methionine known as one of precurser of aflatoxins did not affected the increasing productivity with significance.

Cutaneous chromomycosis is a slow growing verrucous skin infection caused by five species, identified as Philadophara verruscosa, Fonsecaea dermatitidis, Fonsecaea pedrosoi, Fonsecaea compactum, Cladosporium, carionii. We report a case of chromomycosis of the skin causing by Cladosporium genus, in view of its rarity and unique light microscopic and ultrastructural features. This 65-year-old female had suffered from eczematous and lichenified skin lesion for the last two years since she burned her dorsum of the left hand by boiling oil. The lesion was slowly progressed, and ended up to the brownish hardening of the skin covered with crusts. Skin punch biopsy was done. Histologically, the sections revealed typical features of chronic granulomatous inflammation along with the heavy infiltration of the lymphocytes, plasma cells and histiocytes. Pseudocarcinomatous downgrowth of the epidermis and microabscesses in the upper dermis were also found. Numerous thick walled fungal organisms were noted within the giant cells and freely in the dermis, which were positive ant PAS stain, and diastase resistant. Thick mucous capsule is not observed. The organisms showed very faint yellowish walls with a few buddings and a few short elongated hyphae were also noted. Ultrastructurally, the fungus wall was multilayered and inner organelles were sparse. There is no evidence of systemic involvement, especially brain.

Follow-up sonographic studies of three infants, whose initial sonograms showed findings suggestive of choledochal cyst, demonstrated disappearance of cystic dilatation of the common bile ducts. The phenomena could be accounted for by acute common bile duct obstruction secondary to bile sludge. Bile plug syndrome should also be included in the differencial diagnosis. When a cystic or fusiform dilatation of the common bile duct is seen on sonogram. Conservative management must be the choice of approach unless the finding is proven to unchanged over a period of time and irreversible.
