3.Immunohistochemical Study on Expression of Extracellular Matrix Components in Glomerular Diseases.
Korean Journal of Pathology 1994;28(3):288-296
Most glomerular lesions are associated with qualitative and quantitative alterations of the extracellular matrix components, having relation to progressive glomerular sclerosis. We aimed to investigate the characteristic alteraltions in distribution of extracellular matrix components, such as fibronectin, laminin, collagen type III and IV in human glomerular diseases by immunohistochemical method. The materials included are 3 nephrectomy as normal control, 51 renal biopsies and I autopsy; 3 normal, 5 minimal change disease, 5 minimal change disease with minimal mesangial lgA deposit, 5 benign recurrent hematuria, 10 focal segmental glomerulosclerosis, 15 lgA nephropathy, 10 membranoproliferative glomerulonephritis, 2 diffuse mesangial sclerosis of infancy. Type IV collagen and laminin were present normally in the mesangium, GBM, TBM and interstitial vessels, and were increased at the portion of increased mesangial matrix, of sclerosis and thickened GBM in cases of lgA nephropathy, membranoproliferative glomerulonephritis, focal segmental glomrulosclerosis and diffuse mesangial sclerosis in the proportion to the glomerular damage. Type III collagen was absent in the normal glomeruli, but was detectable focally and segmentally in cases of membranoproliferative glomerulonephritis, IgA nephropathy and focal segmental glomerulosclerosis at the sclerotic portion. Fibronectin was normally detectable mainly in the mesangium, and partly and incompletely in GBM, and was increased at the portion of increased mesangial matrix, sclerosis and thickened GBM in cases of focal segmental glomerulosclerosis, membranoproliferative glomerulonephritis, IgA nephropathy and diffuse mesangial sclerosis, but was diminshed at the old slcerotic portion or global sclerosis. The expression of these antibodies in cases of minimal change disease, minimal change disease with minimal mesangial IgA deposit, benign recurrent hematuria was not different, quantitatively and qualitatively, from that of normal glomeruli. These findings suggest that progressive glomerular sclerosis was due to the increase of extraceuular matrix components such as type IV collagen, laminin, fibronectin and new appearance of type III collagen, and the expression was in proportion to the degree of sclerosis, but had no relation to the disease entity.

4.Flow Cytometric DNA Content Analysis in uterine Cervical Cancer.
Korean Journal of Gynecologic Oncology and Colposcopy 1994;5(3):49-53
The DNA ploidy using fresh tissues from 304 cervial cancer were analyzed by flow cytometry in order to evaluate the correlation between DNA ploidy patterns and prognostic factors of uterine cervical cancer. There were l67 diploid cases(55%) and 137 aneuploid(45%). No significant correlation was noted in stage, age and lymph node metastases between diploid and aneuploid tumor. But S-phase fraction and DNA index were higher slightly in cases of lymph node metastases cornpaired to non-metastases. This results suggest that the DNA ploidy cannot be used as an independent prognostic fac- tor, but further evaluation will be needed in order to conclude definite relationship between prognoseic factor and S-phase fraction or DNA index.

5.Expression of c-erbB-2 and p53 Oncogene in Cervical Intraepithelial Neoplasia and Uterine Cervical Carcinoma.
Korean Journal of Obstetrics and Gynecology 1997;40(1):161-169
Recently, the oncogene and tumor suppressor gene have been recognized as important factors that is contribute to conversion and progression from normal cell to cnacer one. In the current study, expression rates of c-erbB-2 and p53 oncoprotein were analysed in biopsy tissues of uterine cervix to learn whether the expression rates of p53 and c-erbB-2 were related with prognostic factors. The c-erbB-2 and p53 expression rates of group with invasive cervical carcinoma versus control group were 53.6% vs 17.7% and 51.4% vs 9.7%, respectively. There was stastically significant elevation of e-erbB-2 and p53 oncogene expression in patients with invasive cervical carcinoma(p < 0.01). In comparison of invasive cervical carcinoma with CIN, there were stastically significant differences in p53 expression rates(51.4% vs 28.9%) and c-erbB-2 expression rates(53.6% vs 20.2%) and co-expression rates(31.1% vs 6.8%)(p < 0.01). Also in CIN patients, CIN III group showed statistically significant elevation than CIN I and CIN II group(p < 0.01). Among histologic cell types, the expression rate of p53 was higher in sqamous cell carcinoma than in adenocarcinoma. Except for the expression rate of p53 according to histologic cell type, no statistical difference in expression rates of c-erbB-2 and p53 were found according to age, clinical stage, lymph node metastasis in invasive cervical carcinoma(p > 0.05). In conlcusion, c-erbB-2 and p53 oncoprotein are thought to be possible factors in the carcinogenesis of cervical carcinoma and correlate with progression of it. But continuous analysis and follow up of 5 year survival are desirable to determine the role as prognostic factor and correlation with prognostic factors.

6.Immunohistochemical Study of bcl - 2 Expression in Basal Cell Carcinoma.
Korean Journal of Dermatology 1997;35(2):242-248
BACKGROUND: Basal cell carcinoma(BCC) is the most common tumor of light-skinned people. Most of them are relatively innocuous, but some may cause extensive tissue destruction, and result in death by local infiltration of vital structure or metastatic disease. The bcl-2 is a protooncogene involved in tumorigenesis by blocking apoptosis or programmed cell death. OBJECTIVE: To investigate whether there was a difference in bcl-2 expression in different histopathological types of BCC. Method: We performed immunohistochemical staining by using a monoclonal mouse anti-human bcl-2 oncoprotein in 28 BCC(nodular: 7 cases, micronodular; 3 cases, adenoid; 1 case, infiltrative; 9 cases, and mixed; 8 cases). Result: All 28 BCC expressed bcl-2, and the degree of staining was different according to histopathological types; poor prognostic micronodular(100%) and infiltrative(73.3%) types were relatively strong, and nodular(66.7% ) and adenoid(75.0%) types were moderate. Conclusion . These results suggest that the degree of bcl-2 expression in BCC seems to be dependent to the histopathological types together with clinical behavior.

7.Digital Vascular Cold Reactions in Korean Farmers during Finger Immersion in Cold Water.
Journal of the Japanese Association of Rural Medicine 1997;46(4):665-678
We investigated the cold reaction of fingers in cold water as a criterion of peripheral resistance to frostbite in order to obtain elementary data to improve farmers' health. Experiments were carried out on 81 farmers and 64 urbanites at 20±2°C, 55±5% RH with sitting position on the floor. The finger skin temperatures of the subjects were measured while the left middle finger of each subject was immersed in cold water or 0°C for 30 minutes and recorded once every one minute with the thermistor. We also compiled statistics on the following items: mean finger skin temperature (MST), finger skin temperature at initial rising after immersion (TFR), time for the appearance of initial rising after immersion (TTR), cold resistance index (RI), etc. The results were as follows RI was higher in farmers than in urbanites, but there was no significant difference between the two groups. In men, RI was lower in farmers than in urbanites, but there was no significant difference between the two groups. By contrast, in women, TFR and RI were significantly higher in farmers than in urbanites. MST was significantly higer in women than in men, but RI was no statistically significant difference. By age, the men in their 30's showed significantly the highest MST and the shortest TFR. RI was significantly higher in the men in their 30's than others. In women, however, the difference in RI was of no statistical significance. By region, MST was the highest in Seoul dwellers. RI was the highest in Okku dwellers, but there was no statistically significant difference among regions.
These results indicated that farmers tended to be higher than urbanites in cold resistance index.
8.Correlations among Physiques, Physical Fitness and Digital Vascular Hunting Reaction during Finger Immersion in Cold Water in Farmers.
Journal of the Japanese Association of Rural Medicine 1999;48(1):1-12
To collect the basic data for the health management of Korean farmers, we investigated physique factors, physical fitness, and cold resistance (by digital vascular hunting reaction during finger immersion in cold water), and examined their correlations in 74 subjects. In men, the stronger the digital vascular hunting reaction was the higher the physical fitness levels. For women, however, the motility of those who showed stronger digital vascular hunting reactions appeared worse. The correlation between physique and hunting reaction appeared weak in men but in women the hunting reaction of obese subjects was stronger than that of slender subjects. Agewise, men in their 30s, 40s and 50s who were short and slim appeared to have better cold-resistance. The men in their 60s who were broad-hipped had better cold-resistance, and the relation between physical fitness and hunting reaction appeared to be negative. In contrast, the women in their 30s whose subcutaneous fat was thinner showed positive hunting reaction, but in their 40s and 50s the correlation among physique, physical fitness, and hunting reaction appeared rather weak. The body fat content in the women aged 60 to 69 was high compared to that in other age groups. Among them, those who had less fat and better physical fitness showed more favorable hunting reactions.
