Immunohistochemical staining was performed in 20 skin granulomas of 16 patients with leprosy using antisera against lysozyme and S-100 protein. In lepromatous leprosy, lysozyme positive cells and S-100 protein positive cells were rarely found in the dermis. However, the histoid leprosy specimen had large numbers of lysozyrne positive cells and S-100 protein positive cells in granuloma. In borderline group, lysozyme positive cells and S-l00 protein positive cells were found in the dermis. S-100 protein positive cells were diffusely distributed throughuut the granuloma in borderline lepromatous leprosy, while they were often found in lymphocytic mantle in borderline tuberculoid leprosy. In tuberculoid leprosy, lysozymal staining was encouritered in epitheloid cells and giant cells, but S-100 protein positive cells were predominantly found encircling granuloma. In the epidermis, great numbers of S-l00 protein positive cells were found in tuberculoid leprosy than in lepromatous leprosy.

PURPOSE: Diabetic nephropathy is the most common cause of end stage renal disease and the incidence is progressively increasing. The aim of this study was to investigate the differences of 99mTc-DMSA renal uptake among diabetic patients with normoalbuminuria, microalbuminuria and overt proteinuria, and then to determine the clinical usefulness of 99mTc-DMSA in predicting early diabetic nephropathy. MATERIALS AND METHODS: 99mTc-DMSA scan was performed and a total renal uptake of 99mTc-DMSA was measured in 145 diabetic patients. Patients were divided into 3 groups according to the amount of 24 hour urinary albumin excretion as Group I (normoalbuminuria, 74 cases), Group II (microalbuminuria, 39 cases), and Group III (overt proteinuria, 32 cases). The differences of 99mTc-DMSA renal uptake among the 3 groups and the correlation between the renal uptake of 99mTc-DMSA and other clinical parameters were analyzed. RESULTS: The total renal uptake of 99mTc-DMSA of Group II (40.8+/-11.0%) was significantly lower than that of Group I (54.4+/-6.3%, p<0.001). The uptake of Group III (27.7+/-12.0%) was significantly lower than those of both GroupI and Group II (p<0.001). 99mTc-DMSA total renal uptakes correlated negatively with serum creatinine level (r=-0.629, p<0.001) and positively correlated with creatinine clearance rate (r=0.702, p<0.001). CONCLUSION: 99mTc-DMSA total renal uptake of diabetic patients with microalbuminuria was significantly decreased compared with that of patients of normoalbuminuria. Therefore, 99mTc-DMSA scan can be used as a diagnostic study for early detection of the diabetic nephropathy.

There is a great variety of abdominal calcifictions of varying etiology. Among them, calcification in gastriccarcinoma is rare. To the best of our knowledge, there has been no previous report of calcifying mucinousadenocarcinoma of the stomach in Korea. In the present communication, we report two cases of this rare tumor. Thefirst case was 27 years old female who had anorexia and palpable mass in the epigastrium. By palpation, a firmnon-tender large mass ws felt in the epigastrium. A plain abdominal film showed numerous pnuctate calcificationsin the left upper quadrant. Film from an upper G-I series demonstrated findings of advanced gastric carcinoma withmultiple punctate calcifications involving the antrum and body. Gastroscopic biopsy proved the lesion to bemucinous adenocarcioma(signet ring cell type). The second case was 38 years old female who compained of nausea,vomiting and weight loss. On physical examination, she appeared normal. Routine laboratory tests were withinnormal limits. A plain abdominal film revealed stippled calcifications in the left upper quadrant medial to thesplenic shadow. The film from an upper G-I series showed a mass in the fundus and upper body of stomach withmultiple stippled calcifications along the lesser curvature. Subtotal gastrectomy was perfomred and the pathologicfindings was calcifying mucinous adenocarcinoma(signet ring cell type).

PURPOSE: We measured pulmonary epithelial permeability by Tc-DTPA radioaerosol clearance in patients with diabetes and correlated with the presence of microangiopathy to understand the pathophysiology of pulmonary microangiopathy and evaluate Tc-DTPA radioaerosol clearance as a diagnostic test to assess pulmonary microangiopathy. MATERIALS AND METHODS: We performed ' Tc-DTPA radioaerosol scan in 10 normal subjects, 10 asym-ptomatic smokers, 20 diabetic patients without history of smoking (10 with microangiopathy, 10 without microangiopathy). Tc-DTPA clearance half-time (T1/2) was calculated, then compared with the result of chest radiography and pulmonary function test. RESULTS: Chest radiography and pulmonary function test were normal in all subjects. There were no significant difference of clinical or laboratory characteristics between these groups except age. The diabetic patients with micraangiopathy were significantly older (p<0.05). The T1/2of normal subjects and asyrnptomatic smokers were significantly different (65.2+23.7min vs 39.6+9.8min, p<0.05). For diabetic patients with microangiopathy, the T, was 90 5+46.5min and significantly delayed when compared with those of normals and asymptomatic smokers (p<0.05). However, the T1/2of diabetic patients without microangiopathy, 70.0+12.7 min, was not significantly different from those of normals or asyrnptomatic smokers (p>0.05). No significant correlation was found between the T1/2and spirometric parameters including DLcc>, FVC, FEV>, FEV(/FVC (%) and FEF)5-75g in all subjects, and between the T1/2 and duration of diabetes in diabetic patients. CONCLUSION: Eventhough the influence of age cant be excluded, delayed Tc-DTPA clearance half-time (T1/2)in diabetic patients with microangiopathy indicates decreased pulmonary cspillary permeability as one of the pathophysiologic results of pulmonary microangiopaththy. Further studies are needed in larger number of age matched control and diabetic patients to evaluate the diagnostic efficacy.

PURPOSE: This study was designed to identify the possible mechanism of insensitivity of DU145 prostate cancer cells to the transforming growth factor (TGF)-beta1-mediated growth inhibition. MATERIALS AND METHODS: DU145 cells were treated with 4, 40, 100 pM TGF-beta1 for 3, 6, 9 days. Initially we performed the growth assay. After that, we analysed the change of cell cycle using fluorescence flow cytometry. At each time point, Western blot analysis with cell pellets was performed to investigate the change of expressions of epidermal growth factor(EGF), TGF-alpha, EGF receptor(EGFR) and TGF receptorII(TbetaR-II) proteins. RESULTS: The growth rate of TGF-beta1-treated cells was initially suppressed, but over time returned to control level. Flow cytometric analysis revealed that TGF-beta1-treated cells showed an increase in apoptotic/G1 phases, and concurrent decrease in S, G2/M phases until 6days. On day 9, however, TGF-beta1-treated cells showed a persistent increase of apoptotic unclei in spite of recovery of apoptotic/G1, S and G2/M phases. Western blot analysis showed that the intensity of EGF or TGF-alpha band decreased in dose-sependent manner on day 6. However, the intensity of each band increased up to the control level on day 9. the expression of EGFR or TbetaR-II protein did not change after treatment of TGF-beta1. CONCLUSIONS: these results suggest that EGF and TGF-alpha sould mediate in part the escape fron the inhibitory effect of TGF-beta1 in DU145 cells.

Excimer laser photorefractive keratectomy(PRK) for myopia has been performed recently by refractive surgeons, in spite of myopic regression and corneal opacity following excimer PRK. We analyzed refractive change, corneal opacity, and uncorrected visual acuity of 313 eyes (233 patients) for one year and 115 eyes(83 patients) for two years after excimer PRK. The patients were divided tnto 3 groups accordign to theit refractive errors [group 1 (n=123 eyes): from -2.25D to -6D, group 2 (n=145 eyes) : from -6.25D to -10D, and group 3 (n=45 eyes): less than -19.25D]. Mean refractive errors one year after excimer PRK were -0.31+/-0.57D, -0.54+/-0.90D, and -1.71+/-2.01D in group 1, 2, and 3, respectively. These errors were increased to -0.45+/-0.68D, -0.90+/-1.20D, and -3.37+/-3.20D two years after excimer PRK in group 1, group 2, and group 3, respectively. These changes were staistically significant in group 2 (p=0.000) and group 3 (p=0.015), not in group 1 (p=0.426). Corneal opacity was more severe in group 3 than in group 1 and 2 and decreased depending on time passing by. Diopteric error within +/-1.0D from the attempted correction one year after excimer PRK was found in 89% of group 1, 74% of group 2, and 40% of group 3. These percentages were after excimer PRK. Uncorrected visual acuity equal to or better than 0.5 were 95% in group 1, 87% in group 2, and only 44% in group 3 two years after excimer PRK. With these results we thought that excimer PRK was effective and safe for myopia more than -6D, while unpredictable for myopia less than6D.
