The effect of Atenolol on the blood pressure were studied in 31 cases of essential hypertension and on the effect of plasma renin activity in 8 cases. There were 8 cases of male with age 49.5(42-70) and 23 cases of female with age 49(35-71) years. 27 cases of 31 cases were untreated hypertensive patients and 4 cases were refractory to hypotensive drugs of diuretics and vasodilators. The Atenolol 50mg once-daily was given to all patients orally for 3 weeks. The blood pressure, heart rate, ECG and symptoms were checked in one week interval. In 8 cases, the plasma renin activity was measured by Dainabot Kit before and after one week medication. The results were as follows: 1. In 27 cases of untreated hypertension, the control blood pressure was 182.9/11.4mmHg in average. The blood pressure decreased in average by 18.3/11mmHg in one week, 23.7/15.9mmHg in two week and 21.5/10.5mmHg in three week. The heart rate also decreased by 7.4/min. in one week, 14.9/min. in two week and 7.8/min. in three week. These data showed considerable reduction of blood pressure and heart rate with 50mg Atenolol once-daily. 2. The basal plasma renin activity after one week medication was reduced by 46% in 8 cases and this data showed considerable reduction regardless control level of basal plasma renin activity. 3. There were considerable blood pressure reduction by adding Atenolol 50mg once-daily to diuretics and vasodilator to which patient's blood pressures were refractory. 4. There was no orthostatic hypotension or serious side effect by Atenolol medication.

The aim of this stud y was to compare the epidermal thinning properties of four corticosteroid ointments applied under occlusion, using histology and histometry. The results were surnmerized as follows: 1.The stratum corneurn was dramatically thinned, appearing as a wispy layer of horny cells as apposed to the norrnal basket-weave configuration. this effect was prominent at sites treated with clobestasol propionate, fluocinonide, and fluocinolone acetonide. 2. With the histometry, visible epidermal thickness wa.s markedly reduced. This effect w is prominent in the following ascending order: fluocinolone acetonide, fluocienonide, clobestasol-17-propionate. Hydrocortisone was the least atrophogenic. 3. Clohestasol-17-propionate and fluocinonide caused significant flattening of dermo-epidermal junction, Fluocinolone acetonide and hydrocortisone caused less pronounced cbanges. 4. Marked capillary dilation af papilly dermis is caused by clobestasol-17-propionate, fluocinonide and fluocinolone acetonide.

Bacterial meningitis results in significant neurologic dificits despite in spite of much effort in the treatment of the disease. This study was performed to determine the incidence of caustive organisms and to correlate between the organisms and computed tomographic (CT) findings with clinical outcome of bacterial meningitis in newborns and infants. We analyzed the brain CT and clinical records of 15 infants who had been diagnosed as bactrial meningitis by CSF culture. We found that the most common organisms were Group B streptococcus in neonates withou no neurologic complications in all but one and Hemophilus influenza in infants whose clinical outomes were poor in all except one. CT findings related with poor prognosis in this study were cerebral edema, basal cistermal obliteration & enhancement, and cerebral infarction on initial CT and ventriculomegaly on follow-up CT. We concluded that CT diagnosed intracranial complications of bacterial meningitis well and could contributed to better treatment of bacterial meningitis.

PURPOSE: To describe MR imaging features of hypoxic brain damage in relation to time elapse and prog-nosis of patients. MATERIALS AND METHODS: We reviewed 19 MR studies of 18 patients with hypoxic brain damage. MR imaging studies were performed between 1 to 20 days after the hypoxic insults (mean 8.6 days). MR images were analyzed with regard to the locations of abnormal signal intensities, the presence of brain edema. And imaging findings were correlated with the time elapse after the insults and the prognosis of patients. RESULTS: On 19 cases of MR studies, abnormal high intensities on T2-weighted images were found in the basal ganglia (15, 78.9%), cerebral cortex (13, 68.4%), white matter (9, 47.4%), thalamus (6, 31.6%), cerebellum (4, 21.1%) and brainstem (1, 5.3%), respectively. Cerebral cortical involvement was typically bilateral and diffuse, but sometimes limited to the parieto-occipital area. The brainstem and cerebellar involvement was rare and in all cases, cerebral cortical lesions accompanied. Most of the white matter lesions were accompanied with cortical and deep gray matter lesions and found in subacute period(>6 days). The cortical high signal intensity lesions on T1-weighted image were found mostly in subacute stage, but in some cases involvement was also found in acute stage (< or =6 days). The cortical edema is found on 11 cases in acute and subacute stages. In cases of recovered consciousness, cortical involvement and edema on MR were rare. CONCLUSION: MR findings of hypoxic brain damage were various, but diffuse bilateral involvement of cortex and/or deep gray matter was found in most of the cases. White matter involvement was rarely found in acute stage and usually found in subacute stage. In cases of good pronosis, cortical involvement and edema were rare.

PURPOSE: To investigate the efficacy and advantages of the lateral approach for internal fixation of the distal humeral shaft fractures. MATERIALS AND METHODS: Twelve patients with distal humeral shaft fractures who underwent open reduction and internal fixation using plate and screws by lateral approach from January, 1997 to May, 2002 were investigated. Postoperative results after a minimum 1 year follow-up were assessed using union rate, elapsed time to union, postoperative complications such as iatrogenic radial nerve palsy, range of motion of the elbow joint. Clinical outcomes were evaluated with Mayo elbow performance scoring system. RESULTS: Union was achieved in all cases. The average time to union was 9 weeks (range, 7~12 weeks). Four cases of preoperative radial nerve palsy were revealed as contusion of the intact nerve and resolved completely by three months. The mean elbow range of motion was from 5 to 138 degrees. The average Mayo elbow performance score was 91 points; 9 cases ranked as excellent and 3 as good. CONCLUSION: Distal humeral shaft fractures can be treated successfully through open reduction and internal fixation using plate and screws. Lateral approach is recommended to stabilize distal humeral shaft fractures without compromising the range of motion of the elbow, and to protect or explore the injured radial nerves easily

STUDY DESIGN: This is a retrospective study analyzing early problems of open discectomy for lumbar intervertebral disc herniation. OBJECTIVES: To analyse the incidence of intraoperative and postoperative problems developed within six weeks and their relationship with reoperation and prognosis. MATERIALS AND METHODS: Hundred and ninty-four patients with intervertebral disc herniation, treated by open discectomy from April 1987 to December 1997, were assessed for intraoperative and postoperative problems. The problems were classified into three degrees : major, moderate and minor problem. when the problem was related to readmission, reoperation and prolonged admission for more than six weeks, it was classified as major problem. When the problem was related to prolongation of duration of admission for two to six weeks, it was classified as moderate problem. When the problem was not related to any prolongation of duration of admission, it was classified as minor one. RESULTS: Seven intraoperative and twenty-three postoperative problems were developed in twenty-seven patients. There were seven major problems : three recurrence of symptom and four suspicious deep infections. Nine moderate problems : six remained radiating pain, two serous discharge from operative wound and one urinary tract infection. and remained fourteen were minor problems : two recurrent symptom, two persistent pain, three serous discharge and seven intraoperative complications. CONCLUSIONS: The early major problems of open discectomy were recurrence of intervertebral disc herniation and deep infections. Problems with remainded radiating pain usually don't need reoperation and those symptoms were relieved with time goes. The prognosis was not influenced by minor problems.

To evaluate the clinical significance of anomalous pancreaticobiliary ductal union(PBDU), we analysed 11 cases(0.19%) of anomalous PBDU among 5675 cases performed ERCP from Jan. 1973 to Aug. 1992. According to the classification of Kimura et al., 4 cases were type 1(P-C union) and 7 cases type 2(C-P union). The length of common channel ranged from 1.5 cm to 3.1 cm(mean 1.9 cm). The common associated disease were choledochal cyst(7 cases), carcinoma of the gallbladder(5 cases) and biliary stone(3 cases). Four cases of carcinoma of the gallbladder were type 1. The incidence of anomalous PBDU was significantly higher in cases with carcinoma of the gallbladder(5 cases among 49 cases) than in case without carcinoma of the gallbladder(6 cases among 5626 cases). And the incidence of gallbladder carcinoma(45%) among the 11 cases of anomalous PBDU was significantly higher than that(0.78%) among those who did not have anomalous PBDU. In conclusion, the common associated diseases with the anomalous PBDU were choledochal cyst, carcinoma of the gallbladder and stone, and the anomalous PBDU may be risk factor in the development of carcinoma of the gllbladder.

The aim of this report is to show that treadmill running exercise under well-controlled conditions is to improve of regeneration in rat gastrocnemius muscles after physical injury. For this, rats were submitted to bouts of exercise on a treadmill up a 10 degrees decline for 60 min and gastrocnemius muscles were analysed at different exercise periods by immunohistochemistry in comparison with injured nonexercised muscles. Rats were used with guidelines for experimental procedures as set forth in the Declaration of Helsinki. We analysed the regenerative processes by detection of immunoreactivity for the two intermediate filaments, desmin and vimentin. Desmin and vimentin are specific components of the cytoskeleton of striated muscle fibers and of mononuclear cells of mesenchymal origin including myoblasts, respectively. We found that non-exercised rats had more desmin-and vimentin-positive myofibers than that of exercised rats at 9th, 16th, 23th, 30th day after physical injury. At 30th day, non-exercised rats had several desmin-and vimentinpositive myofibers, but exercised rats had numerous normal myofibers. These results show that exercise is able to improve regeneration processes in physical injured gastrocnemius muscles of rats.
