To address the possible prognostic value of p53 and Bcl-2 proteins in non-small cell lung carcinomas (NSCLCs), the authors studied 43 cases of NSCLCs diagnosed between the years 1990 to 1995 at Pusan National University Hospital. The patients were treated either by pneumonectomy or lobectomy of the lung. The expression of p53 and Bcl-2 proteins was semiquantitatively analyzed in paraffin sections by immunohistochemical method and correlated with clinicopathologic prognostic parameters of NSCLCs. Overexpression of the p53 protein was found in 31 cases (72.1%) of the 43 NSCLCs. Overexpression of the p53 protein was significantly correlated with the decreasing degree of histologic differentiation, increasing tumor stage, and cigarette smoking. Bcl-2 expression was found in 19 cases (44.2%) of the 43 NSCLCs. Increased expression of the Bcl-2 protein was significantly correlated only with decreasing tumor stage. An inverse relationship was found between p53 and Bcl-2 proteins, but it was not statistically significant. Thus p53 and Bcl-2 proteins, as demonstrated immunohistochemically in routine paraffin sections, could be of value in prediction of the aggressiveness and prognosis of NSCLCs, in agreement with the central role of p53 and Bcl-2 proteins in the evolution of NSCLCs associated with cigarette smoking.

Xanthogranulomatous cholecystitis is a rare form of inflammatory disease of the gall bladder and was first described in 1970 by Christensen and Ishak as fibroxanthogranulomatous inflammation of the gall bladder. Recently authors experienced three cases of xanthogranulomatous cholecystitis, two of which were erroneously diagnosed as malignant tumor in preoperative clinical and radiological examinations. Grossly, the gallbladders were enlarged and the walls were thickened with yellowish granular necrotic areas ranging from a few millimeters to 1.0 cm in diameter. Microscopically, all of three cases showed diffuse infiltration of the foamy histiocytes containing bile pigments and mononuclear leukocytes associated with fibroblastic proliferation and foreign body reactions. The pathogenesis of the xanthogranulomatous cholecystitis is uncertain, but opinion favours an inflammatory response to extravasated bile probably, from ruptured Rokitanky-Aschoff sinuses. Three cases of xanthogranulomatous cholecystitis with brief review of literature are presented.

Human rotavirus has now been established as the leading cause of gastroenteritis in young children worldwide. At least fourteen serotypes of group A rotavirus have been identified on the basis of antibody responses to major neutralizing glycoprotein, VP7 (G type for glycoprotein), present in the outer capsid of the virus. Serotype 1, 2, 3 and 4 are the most highly prevalent in human. In Korea, rotavirus is also the principal cause of severe nonbacterial diarrhea requiring hospitalization in infants and young children, which is commonly detected by EIA method. The epidemiology of rotavirus infection has been monitored by only serologic methods without electropherotyping in Korea. This study shows seasonal and age related variations .of rotavirus infection in Korea according to the genotype using the reverse transcription polymerase chain reaction (RT-PCR). Fecal specimens were obtained from 39 children hospitalized with acute watery diarrhea and gastroenteritis in Ewha Womans University MokDong Hospital in Seoul from Jan. to Dec. of 1996. All four (1, 2, 3, 4) major G serotypes were identified by amplification of segment of the gene for VP7 using RT-PCR. Rotavirus Gl 749 bp, G2 653 bp, G3 374 bp and G4 583bp were shown on 2.9 or 3.3% NuSieve agar gel. Results were as follows: 1) Rotavirus was detected at 53.8% (21/39) by EIA and 89.7% (35/39) by RT-PCR. 2) Serotype Gl, G2, G3, G4 when detected by RT-PCR accounted for 80.0% (28/35), 14.3% (5/35), 2.9% (1/35) and 2.9% (1/35), respectively. 3) Thirty five strains of rotavirus were detected at the frequency of 17.1% (6/35) in Oct., 20.0% (7/35) in Nov. and 20.0% (7/35) in Dec. 4) As for the age range, children affected by rotavirus were mostly under 1 years.

Black adenoma is known to be a rare variant of adrenal cortical adenoma containing characteristic abundant lipofuscin pigments in the cytoplasm. Almost all of them are nonfunctioning and only occasionally they are associated with Cushing's syndrome or primary hyperaldosteronism. We present two cases of black cortical adenoma of the adrenal gland associated with Cushing's syndrome in a 24-year-old woman and a 64-year-old man. This report dealt with clinical and pathologic presentation including ultrastructural identification of lipofuscin pigment.

A typical case of gelinerazed cutalineous lichen amyloidosus is reported. A 62-year-old female had had brownish papular lesions on the lower legs, hands, and shoulders for about 8 years. Three years later, the papular lesions extended through the whole body surface. She complained of severe itching and tingling sensation. Physical findings were confined to the skin. The skin lesions were diffusely distributed. The size of the lesion was from pin-head to rice, The color was dark brownish. The papules were over generalized skin except for the face, palms, and sole.. Diagnosis was made by the characteristic clinical manifestations and histopathologic findings of the skin. However, the specimens of the liver and rectal biopsies did not show amyloid deposits. Based on these findings, authors concluded that this is a case of generalized cutaneous lichen amvloidosus and this is the second case in the literature in Korea. Even though the subjective symptom such as itching is getting decrease, the clinical course of this disease could not be aliernated by classical and conventional therapeutic regimens.

The purpose of this study is to clarify success factors for desirable relationship between buyer and supplier in elementary school. Therefore, the survey questionnaire consisted of general background, past success, success difference, buyer-supplier relationship characteristics(trust, supporting status, communication behavior, conflict resolution techniques, supplier selection process). The subjects were 66 dieticians of elementary school in Inchon. The statistical analysis of data was completed using SPSS program. The results were summarized as follows : Average total cost/day per one person 1,156Won. The number of suppliers per one school were 6. 92.3% of the subjects were in favor of private contract, regarding contract methods of purchasing food materials. For the past success, degree of satisfaction about past their supplier showed 3.49 score. The present success difference was shown higher than the past success. There was significant correlation between the past success and the present success difference. Trust about suppliers showed 3.40score. Supplying companies hardly support for buying school. Among information quality(timely, accurate, adequate, complete, credible), timely and complete showed lower score than the other kind of elements. Among the buyer-supplier relationship characteristic elements, only trust correlated with satisfaction about suppliers significantly. Among the conflict resolution techniques, joint problem solving and persuasive attempts were often made use of by subjects. The supplier selection criteria were shown quality(7.47), supplier's capabilities(6.46), management plan(6.00), price(5.73), scale(5.48), assets(5.27), considers delivery(4.76) and technology(2.39). As results, trust was needed for the desirable relationship between buyers and suppliers. This study has some limitations. The data in this study were collected from only buyer. It is more desired to acquire data from suppliers also.
