2.Immunohistochemical Study of the Expression of p53, Pan-ras, c-erbB-2 and PCNA in N-Nitrosomorpholine(NNM)-Induced Hepatocellular Carcinoma of Rats.
Korean Journal of Pathology 1995;29(6):727-739
The focus of this study was o aialyze the morphologic expression of p53, Pan-ras, c-erbB-2, and PCNA in preneoplastic and neoplastic liver lesions induced with NNM of rats. The development of hepatocellular tumors was investigated by histology and electron microscope in 65 Splague-Dawley rats administered with NNM in drinking water at low dose(5 mg/100 ml) and high dose(20 mg/100 ml). Three types of hepatocytic degeneration glycogenotic, eosinophilic and basophilic changes were followed by the appearance of hepatocellullar carcinoma. Hepatocellular carcinoma was increased in number and size according to NNM dosage and to duration of exposure. The histological classifications of hepatocelular carcinoma wer trabecular type, which was which was the most common, large eosinophilic, small cell, adenocarcinomatous and clear cell type. The expression of p53, Pan-ras, c-erbB-2 PCNA was examined by immunohistochemical stains. Eosinophilic degeneration revealed mild positivity at 18-26 weeks for expression of all oncogenic proteins studied and PCNA, whereas precancerous lesions showed variable expression from negative to moderate positivity on PCNA. Hepatocellular carcinoma lesions showed strong positivity for all stains and increased intensity during experimental period. These may indicate that chemical carcinogen produce hepatic eosinophilic degeneration and preCancerOus lesions by genetic mutation, resulting in hepatocellular carcinoma.

Some of the proteins of mycobacteria are preferentially associated with the cell wall and are powerful immunogens, and humoral antibody responses to these mycobacterial antigens may occur in patients with tuberculosis. In this study, Triton X-100 solubilized protein (TSP) antigen was isolated from Mycobacterium tuberculosis H37Rv by overnight shaking with 1% Triton X- 100/PMSF and 10-90% ammonium sulfate precipitation. IgG and IgM antibody levels against TSP, crude protein from the unheated cultrue filtrate (CF#) and 30 kDa antigens were determined in the sera of 80 patients with pulmonary tuberculosis and 99 healthy controls with PPD (+) and (-). High IgG reactivity to TSP and CF antigen was observed in tuberculosis patients. Mean IgG antibody titers against all of three mycobacterial antigens were differed significantly (P<0.01) between patients and controls but IgM showed no difference. By the cut-off value adding 2 standard deviation to the mean absorbance of controls, the sensitivity and specificity of the IgG antibody to TSP antigen were 93.9% and 77.5%. The specificity to TSP antigen was a litttle higher than those obtained by CF and 30 kDa antigen. From the above results, the TSP antigen may be useful for the serodiagnosis of tuberculosis.

PURPOSE: There have been repoty on radiological features of lower respiratory track infection in infants and children caused by RSV(respiratory syncytial virus) in KOREA. The aims of this study were to summarize radiological features of lower respiratory tract infection caused by common viral agents other than RSV and to find any specific radiological features which might provide clue to the etiologic diagnosis. MATERIALS AND METHODS: We retrospectively analyzed radiological features in 51 children with symptoms of lower respiratory tract infection and identification of viral agents(except RSV). They included parainfluenza (n=22), adenovirus(n=16), influenza A(n--11), influenza B(n=2) virus infections. The mean age of the patients was 23 months. RESULTS: Major radiological findings of viral lower respiratory tract infection were bilateral parahilar peribronchial infiltration(62%), bilateral overaeration(60%), atelectasis(59%)(segmental or subsegmental atelectasis(43%), Iobar atelectasis(16%)) and patchy or confluent consolidation(20%). Pleural effusion was seen in only one case and hilar adenopathy was not observed in any of them. In the cares of adeno virus, consolidation was seen in 5 cases(31%) including 3 cases919%) of extensive confluent consolidations and overaerations were less frequent findings(44%) than in other viruses. In 24 patients with radiological follow up for more than 1 week, consolidation improved most rapidly, while was persistent atelectasis. CONCLUSION: The major radiologic features in vital lower respiratory tract infection(except RSV) were overinflation, bilateral peribronchial infiltration and atelectasis. In adenoviral infection, confluent consolidations which are usually seen in bacterial pneumonia were more common findings than in other viral lower respiratory tract infections.
