PURPOSE: It has been generally known that prostatic volume is increased related to aging process and changing in hormonal environment, so lower urinary tract symptoms develops. But, our experience has revealed the decrease of prostatic volume in many cases with lower urinary tract symptoms despite aging. MATERIALS AND METHODS: The numbers of patient underwent TRUS were 301 cases. Among the patients who had visited urologic outpatient clinic from march, 1993 to march, 1996, transrectal ultrasonography of prostate was applied to patient with following conditions. 1) over 8 in IPSS with or without enlarged evidence from digital rectal examination 2) enlarged evidence from digital rectal examination 3) no symptomatic relief after 2weeks therapy with alpha blocker 4) when the patient wants more evaluation. RESULTS: Decrease of prostatic volume were shown in 66cases(22%) despite lower urinary tract symptoms. CONCLUSIONS: In our experience, many patients with lower urinary tract symptoms showed decrease of prostatic volume. So, we expect that many more cases of decrease of prostatic volume can be seen among asymptomatic cases with age. Because we can guess that prostatic volume can be influenced by racial differences and dietary habit, we also believe that further evaluation and investigation of this nature is needed.

This Study was performed to investigate the effect of foods containing benzoic acid on the urinary hippuric acid concentration in the toluene exposed workers. The urinary hippuric acid concentration were measured at 0, 30, 60, 90, 120, and 150 minute after intake of soft drink and bread containing benzoic .acid: in volunteers,: who did not have been exposed toluene occupationally. After that urinary hippuric: acids also were measured at the end of shift in toluene exposed workers. And also the concentration of toluene in air were analysed! by gas chromatography. So the relationships between urinary hippuric acid concentration and age, work duration, concentration of toluene in air and intake of benzoic acid containing food were observed. The results were as follows: 1. The urinary hippuric acid concentration reached the highest level at 30 minute after intake of soft drink with bread at a level of 1.41g/g creatinine and soft drink; alone at a level of 1.04g/g creatinine which contained benzoic acid among unexposed toluene, and then gradually decreased. 2. In toluene exposed group no significant effect of general; characteristics siich; as gender, age, work duration, drinking and smoking on urinary: hippuric acid concentration was showed in toluene exposed group. 3. The mean value of urinary hippuric acid concentration of group taking benzoic acid containing foods was significantly higher than that of group not taking. 4. Multiple regression analysis showed that toluene concentration in .air and benzoic acid containing foods were together significantly influence on urinary ; hippuric acid concentration. And the function between variables is Y = 0.014Tpluene +0.489Benzoic acid +0.745 and the contribution rates were 31%. In conclusion, it was suggested that the information on intake of benzoic acid containing foods should be considered in measurement of urinary hippuric acid for the more accurate toluene exposure evaluation.

To elucidate the significance of the nesidiodysplasia of pancreas, histological re-evaluation and immunohistochemical studies for insulin, glucagon and somatostatin were done on 16 consecutive cases (5 premature babies, 2 stillborns, 5 infants and 3 adults) in which paraffin blocks of the pancreas were available. Only one infant was hypoglycemic. All 16 pancreases showed changes of nesidiodysplasia which appeared immunohistochemically to have isulin, glucagon and /or somatostatin. The histologic patterns of nesidiodysplasia included ductoendocrine proliferation, endocrine cell dysplasia, adenomatosis, septal islet, islket cell hypertrophy and islet hypertrophy. All the patterns of nesidiodysplasia except for the adenomatosis were seen in premature babies, infants, stillborns and adults with or without hypoglycemia. The adenomatosis was found only in the hypoglycemic infant. The result suggests that all patterns of nesidiodysplasia of other than the adenomatosis does not imply the pathologic basis of hypoglycemia.

INTRODUCTION: It has been proposed that narcolepsy and REM sleep behavior disorder (RBD) have overlapped symptom profile and pathophysiology. This study was aimed at measuring and comparing changes in EEG frequency band of REM sleep in narcolepsy and RBD, applying EEG spectral analysis method. METHODS: Nine patients diagnosed as narcolepsy and the same number of RBD patients were studied. Spectral analysis of the REM sleep EEG was performed in each patient on 9 epochs selected evenly from the first, second, and third REM periods. Then, we compared frequency band percentages of REM sleep EEG in narcolepsy and RBD. RESULTS: Narcolepsy patients had significantly higher delta frequency ratio than RBD ones (p=0.00). In alpha and beta2 frequency bands, RBD patients showed higher percentage than narcolepsy ones. Slow wave sleep was more prevalent in narcolepsy patients. But, no difference of REM sleep percentage was found between the two groups (p=0.93). CONCLUSION: Higher delta frequency ratio in REM sleep of narcolepsy patients than RBD ones reflects that sleep-promoting mechanism is more dominant in narcolepsy than in RBD.

Verrucous hemangioma is congenital hemangioma, which is structural varients of capillary or cavernous hemangioma. And it is vascular malformation, in which reactive epidermal acanthosis, papillomatosis, hyperkeratosis develope secondarily. Though foreign anthors have reported some cases of this disease, it is rare hemangioma and it never has been reported in Korea. This 13 year-old, healthy female patient has erythematous patchs on her left knee at birth. It grew become coin to egg sized. Because of verrcous iuflammatory reaction of irregular verrucous surfaced plague, the lesion become necrotic thick crusty plague with severe offensive odor and patient complained of severe pain & motion limitation on her left knee. Urinalysis, C B C, chest PA were within normal limit. PPD test was negative. Lt. knee AP & lat. revealed. Marked destroyed soft tissue on anterior portion of Lt. knee and no bony pathological changes were demonstrable. Histopathologica.11y, hyperkeratosis, parakeratosis, acanthosis, papillomatosis in the epidermis and numerous capillary lumina, capillary dilatation, proliferation of endothelial cells and mild infiltration of inflammatory cells in the Dermis. And fibrosis in the Dermis & Subcutaneous tissue are seen.
