To evaluate the morphologic changes of the renal arteries in the condition of high-salt diet, we scheduled the control group which fed routine animal diet added 0.06% of Sodium chloride, low-salt group which fed with 2.0% of sodium chloride, and high-Salt group which fed with 8.0% of sodium chloride. The experimental animals were sacrificed every two weed until 20 weeks of final experimental week. The results obtained were as follow; 1. Slight intimal thickening of the renal arteries is observed from 16th experimental week and continued the end of the experiment in the rats of control group. 2. In low-salt group slight intimal thickening of the renal arteries is observed from 12th experimental week and continued to the end of the experiment. 3. In high-salt group the intimal thickening began from 6th experimental week and its degree was hasten with week, and provoked moderate to high degree of lesion at the end of the experiment. Medial proliferation and degeneration of the intima and media, though their quality is mild, also associated at the end of the experiment.

Epidermoid Cyst is a very rare benign neoplasm of the testis which represents about 1% of all testicular tumors. Ultrasonography findings of epidermoid cyst are so variable in reported cases that it is not eas y to diagnose preoperatively. The echogenecity of mixed echoic. it may show hyperechoic rim, and rarely shows target apperance. Target appearance may be a specific finding of epidermoid cyst, and it may be helpful to diagnose preoperatively. we describe a case of epidermoid cyst of the testis demonstrating double target sign on ultrasonography.

BACKGROUND: To comparatively analysis the epidemiological changes in the acute drug intoxication between 1980s and 1990s. METHODS: We reviewed retrospectively the medical records of the patients with acute drug intoxication in the emergency department of the Inha hospital from June 1986 to April 1987 and from June 1996 to May 1997. And we performed comparative analysis between two result. RESULTS: The ratio of the acute drug intoxication in the emergency medical center was reduced significantly in 1990s against 1980s. Sexual ratio and prevalent age group has no significant interval changes between 1980s and 1990s. The prevalent seasons were Spring in 1980s and Summer in 1990s but has no significance. The most commonly used drugs was rodentides in 1980s and hypnosedatives in 1990s and shown significant interval changes. The most common motive was suicidal attempts in both 1980s and 1990s, but significantly reduced. After emergency treatment the rate of curative-discharge has improved and the rate of admission has decreased significantly in 1990s against 1980s. The most critical agent was agricultural chemicals in both 1980s and 1990s. The mortality rate has no significant interval changes. CONCLUSION: There were some significant interval changes of the acute drug intoxication in prevalence rate, commonly used drugs, ratio of suicidal attempt and curative-discharge rate between 1980s and 1990s. New education programs far preventing acute drug intoxication and strict legal control of drugs are important and necessary.

Seventeen cases of Kienbock's disease were treated since 1982, and analysed their clinical outcomes to confine the pathogenesis and to make sure the best way to treat them in various stages. It was not related to trauma around wrist joint (35.3%) but significantly closed to ulnar negative variances(64.7%). Ulnar tilt angle was increased definitely upto 28.9° compared with normal value (22°) in ulnar negative variance, but volar tilt angle was within normal limits. The packing with tensor fascia lata or palmaris longus tendon after the complete excision of avascular lunate could not prevent the collapse of carpal bones at long-term follow-up. But the triscaphe fusion was most effective to maintain the normal wrist anatomy, and radial shortening than ulnar lengtherning is thought to be more effective in wrist biomechanics of kienbock's disease with ulnar negative variances.

PURPOSE: To evaluate ultrasonographic findings and usefulness in the diagnosis of breast diseases during pregnancy and lactati ng period. METHODS AND MATERIALS: The authors evaluated the ultrasonographic findings of 18 breast diseases during pregnancy and lactation retrospectively. The ultrasonographic examinations were performed with linear-array 5 MHz transducer (ATL). Final diagnoses were obtained by the excisional biopsy, fine needle aspiration and clinical follow-up. RESULTS: Total 18 cases of breast diseases were consisted of 8 cases of galactocele, 4 cases of fibroadenoma, 3 cases of axillary accessory breast, 2 cases of lactating adenoma, and I case of phylloides tumor. The ultrasonographic findings of the above breast diseases were valuable in the diagnosis and therapeutic planning. CONCLUSION: Ultrasonography is the initial and useful method of diagnosing breast diseases during pregnancy and lactating period.

BACKGROUND: Dizziness is a common complaint in patients presenting to the emergency room and that has various pathologic causes. This study investigate the clinical differences in dizziness between the central origin and the peripheral origin and to provides the clues far diagnosis and proper treatment. METHODS: We analysed 290 patients with dizziness during 12 months period prospectively, who visited in ED, Inha University Hospital from Jan. 1997 to Dec. 1997. We analysized sex ratio, characteristics of the dizziness, associated past illness, associated symptoms, severity, results of the special radiologic study, nystagmus type, and causes of central origin and peripheral origin dizziness. RESULTS: Male to female ratio was 1:1.4 in central origin(n=165) and 1:2.0 in peripheral origin(n=125). Most common age group was 11th decade in both groups. According to the characteristics of the dizziness, rotation sense was the main complaint of the peripheral origin dizziness. Most common past illness was hypertension in both groups. MRI has diagnostic priority than CT scan in central origin dizziness. Types of nystagmus has some significant differences between two groups. CONCLUSION: Dizziness may represented as a sign of significant pathological neurologic status especially in central origin. So we must precisely evaluate the patient history, neurologic examination of the inner ear and CNS, and special radiologic study incliding MRI.
