The exact analysis of urinary calculi is very important to study of the etiology of calculus formation, prevention of recurrence and medical treatment. Compared with all the other method, the infrared spectroscopic analysis furnished a permanent record in a very short time. And it is ideal method for qualitative identification and semiquantitative estimation of small fractions of calculi by simple procedure rapidly. A retrospective review of stone analysis by infrared spectroscopy, with KBr tablet method was performed in 105 cases of 219 urinary stone patients, who had been admitted to the Fatima Hospital from May, 1980 to December, 1983. And the following results were obtained 1. Mixed calculus is more than single calculus(1 : 1.56) . The most common type of calculi is calcium oxalatetribasic calcium phosphate (47.6%) . And the most common type of single calculi is calcium oxalate (29.5%) . 2. The most common type of component is calcium oxalate (55.6%) 3. Calcium oxalate-tribasic calcium phosphate is the most common type in the renal (46.2%) and the ureteral stones (53%) . But in the bladder stones, magnesium ammonium phosphate is the most ( 33.3%). 4. Among the 10 laminated stones, 4 cases contain the different components in nucleus and outermost layer 5. Pyuria is observed in 48.6% of all urinary stone patients, in 32.3% of calcium oxalate stone and in more than 80% of magnesium ammonium phosphate stone. 6. Calcium oxalate stone is most common in the age of 20, calcium oxalate-tribasic calcium phosphate stone are in the age of 20 & 30, and magnesium ammonium phosphate stone is above the age of 40.

PURPOSE: To compare the diagnostic accuracy between fine needle and large cutting needle biopies. METHODS & MATERIALS: Chest lesion was biopsied consecutively by 19 G or 22 G fine needle and 14 G large cutting needle with interval of 10-20 min. 119 patients confirmed by operation or clinical follow-up were evaluated. RESULTS: There were 65 patient confirmed as malignant lesion and 54 confirmed as benign lesions. Diagnostic accuracy was 87.7%(57/65) for malignancy and 85.2%(46/54) for benign lesion with fine needle. With large cutting needle, it was 90.8%(59/65) for malignancy and 88.9%(48/54) for benign lesion. In the benign lesion, specific diagnostic accuray was 48.1%(26/54) with fine needle, and 64.8%(35/54) with large cutting needle biopsy, respectively. Complications were hemoptysis(n=13, 10.9%), pneumothorax(n=7, 5.9%) and mild to moderate chest pain. Although, it is impossible to compare the complications by the two types of biopsy on same lesion, 10 cases of immediate hemopytsis and more severe chest pain occurred when large cutting needle biopsy was done. CONCLUSION: No significant difference in diagnostic accuracy between fine needle and large cutting needle biopsies was observed in malignant lesion. In benign lesions, larger sample volume may increase the chance of obtaining a specific diagnosis but has no influence on overall diagnostic accuracy of benignity. Thus, we believe that fine needle aspiration biopsy is an accurate, safe, and more tolerable means to be performed as first step for diagnosis of chest lesions.

A total 49 strains of Escherichia coli suspected of causative organisms of urinary tract infection were isolated and studies for several properties related to the virulence markers of organisms. Urinary isolates (42.9%) showed higher frequency of mannose resistant hemaglutination (MRHA) with human erythrocytes (O type, Rh+) than stool isolates (13.3%) as a control group. Fifteen strains (30.6%) of urinary isolates and 2 (l3.3%) of stool isolates showed hemolysis on blood agar plate. Fourteen strains (28.6%) of urinary isolates and 5 (33.3%) of stool isolates produced colicin. Twelve strains (52.5%) among 23 strains of positive MRHA reaction and 5 (12.2%) of 41 non-MRHA strains found to be hemolytic effect but the frequency of transferable antimicrobial resistance of non MRHA strains was greater than that of MRHA strains. Three properties of hemaglutination, hemolysis, and colicin production were not transferred to recipient E. coli ML 14lO and/or RG 488 by conjugation whereas the antimicrobial resistance were transferred. There was not any significant difference of the minimal inhibitory concentration of 11 drugs between both groups of hemaglutinating and non-hemaglutinating strains. * A thesis submitted to the Committee of the Graduate School of Kyung Pook National University in partial fulfillment of the requirements for the degree of Master of Medical Science in June 1985.
