Allelic deletions involving the short arm of chromosome 3(3p13-21.1) have been observed frequently in cervical carcinomas. Recently the fragile histidine triad(FHIT) gene was cloned and mapped to this chromosomal region(3p14.2). From various studies involving tumor cell lines and primary cancers, the FHIT gene has been presumed to be a candidate for tumor suppressor gene involving various tumors. In FHIT gene, the most common aphidicolin-inducible fragile site, FRA3B exists and the FRA3B has been considered as a region of the spontaneous integration site of HPV 16. In order to elucidate the role of the FHIT in carcinogenesis of cervical cancer, this study was designed to investigate both the expression of FHIT protein in normal, preinvasive and invasive cancer samples employing immunohistochemical study and allelic loss of FHIT gene locus against several microsatellite markers employing the PCR analysis. Immunohistochemical studies of FHIT protein revealed following features. In normal ectocervical squamous epithelium, the expression of FHIT was relatively weak and confined to the basal layer, but in normal endocervical glandular epithelium it was very strong. The expression of FHIT was reduced as the tumor progressed from early lesion to invasive cancer. The koilocytosis was associated with diminished expression of FHIT protein. The study of allelic loss of FHIT gene locus was undertaken against two intragenic (D3S1300, D3S1234) and one extragenic (D3S1295) microsatellite markers. The 5th intron, D3S1300, showed allelic change in 6 of 15 assays and 7th intron, D3S1234 showed allelic change in 10 of 29 assays. There was no apparent LOH from 29 assays in D3S1295. In conclusion, the expression of FHIT protein was markedly reduced or absent in cervical squamous cell carcinoma and the chromosome breakage in FHIT region might be related to the diminished expression of FHIT. On the basis of the reduced expression of FHIT and its encompassment of FRA3B region, it is suggested that disruption of FHIT, a putative tumor suppressor gene, might be the mechanism by which HPV infection enhances cervical tumorigenesis and clonal outgrowth.

Giant cell arteritis is a focal granulomatous inflammation of arteries of medium and small size that affects principally the cranial vessels, especially the temporal arteries, in older individuals. It appears to be a localized process; its significance apparantly depends on the organ affected. A 67-year-old man was admitted to hospital because of the left scrotal mass and pain lasting for 1 month. On physical examination, the hard masses were palpated at the superior part of the left epididymis without tenderness. Histologically, the spermatic cord showed granulomatous arteritis involving the small and medium sized arteries with a transmural inflammatory infiltrates centered on the inner media, and composed of lymphocytes, histiocytes, some eosinophils and multinucleated giant cells. The elastic tissue stain revealed the fragmentation of the internal elastic lamina along with numerous epithelioid histiocytes and giant cells.

E-cadherin (ECD) is a Ca++ -dependent adhesion molecule which plays a major role in the maintenance of intercellular adhesion in epithelial tissues. The expression pattern of ECD in 77 surgically resected gastric adenocarcinomas was examined by immunohistochemistry, using a rat monoclonal antibody raised against murine E-cadherin (DECAM-1). ECD was strongly expressed uniformly at cell to cell borders in normal gastric epithelium without exception. But, various staining patterns were observed in the cancer tissues. The frequency of tumors with preserved ECD expression (Pre-type) and reduced ECD expression (Rd-type) was 44% and 56%, respectively. Using Lauren's classification, the high frequency of the Pre-type expression in adenocarcinoma of the intestinal type was significantly higher than that in adenocarcinoma of the diffuse type (p<0.05). But, no significant correlation between the ECD expression and the gross type, invasion depth, growth pattern or metastasis was observed. These results suggest that ECD might play a key role in the morphogenesis of gastric adenocarcinoma.

Although there have been many reports about the importance of the spleen's role in hepatic fibrogenesis, the exact mechanism is still uncertain. The author designed this study to evaluate splenic function on hepatic fibrogenesis. The degree of hepatic fibrosis and the population of splenocyte subsets were studied in the experimental animal model with fibrosis produced by injecting normal swine serum intra-peritoneally into Sprague-Dawley rats. The animals were divided into three groups; group A was subjected to injection of swine serum only, group B swine serum and complete Freund's adjuvant and group C swine serum and cyclosporin A. The experimental hepatic fibrogenesis by swine serum was augumented by coinjection with the adjuvant and inhibited by cyclosporin A. The study of the splenocyte subset revealed increased percentages of spienic B cell and CD4+ cell and a decreased percentage of CD8+ cell, and these changes of splenocyte subset were also augumented by the adjuvant and inhibited by cyclosporin A. The percent of monocytes was not significantly altered, although a tendancy of early decrease by the adjuvant was noted.

Oral mucositis continues to be a major complaint of patients who have chemotherapy for the acute leukemia. An innovative and inexpensive remedy which produces favorable results for those afficted is not yet introduced. So we tried to develop two oral care protocols for reducing the level of oral mucositis during cytotoxic therapy through literature review and our clinical experience. The one is sodium bicarbonate-normal saline gargling, and the other consists of chlorhexidine gargling. This quasi-experimental study was performed to compare the efficacy of these two different oral care protocols. Twenty subjects were assigned to one of the two specific diagnosis of leukemia, aim of the chemotherapy. The Oral Assessment Guide(OAG), the Beck's perception of oral comfort, WHO Grading system fot mucositis and the discomfort of oral gargling solution were used to assess oral status and subject's oral discomfort during chemotherapy. Each subjects were observed daily from the start of the chemotherapy until Absolute Neutrophil Count(ANC) reached 1,000. It continued about 2-4 weeks. The data analyzed by Mann-Whittney U test and ANCOVA. The result was follows as: The patient who used sodium bicarbonate-normal saline gargling showed significantly higher mean score of the discomfort of oral gargling solution than chlorhexidine gargling. The other scores were not significantly different between two groups. However the subjects using the sodium bicarbonate-normal saline gargling showed a lower level of oral mucositis. We concluded that oral using sodium bicarbonate-normal saline gargling was between to reduce the level of oral mucositis during chemotherapy and nursing assessments of the oral cavity seemed to promote patient's compliance with the oral care regimen.

Congenital obstuction of pulmonary vein without anomalous drainage can cause long-standing pulmonary congestion and pulmonary arterial hypertension, and it may include stenosis of individual pulmonary veinsor total pulmonary vein atresia. We reviewed seven cases of pulmonary vein obstruction, five of which accompanied other cardiac anomalies. Right pulmonary veins were involved in all seven cases including one bilateral case. Pulmonary veins were occluded totally in five and partially in three lungs. Pumonary catheterization and angiography were done for diagnosis. Chest radiographs of total occlusion cases showed decreased lung volume, features of pulmonary edema, interstitial lesions, and pleural thickening, which were quite specific, whereas pulmonry venous dilatation was dominant findings in partial obstruction cases. Pulmonary perfusion scans (n=3) showed total perfusion defects in the cases of total occlusion of veins. MR imaging (n=2) demonstrated total occlusion of pulmonary veins in the venoatrial junction in two, and membranous focal obstruction in one lung. Two patients had pneumonectomy and histological confirmation, Although catheterization and angiography are essential for the diagnosis, MR imaging is thought to be useful for the diagnosis of pulmonary vein obstruction.
