CT from fortynine patients with 53 surgical disc explorations were reviewed and correlated with surgicalfindings. The results were as follows: 1. Frequent locations of HNP were in L4–5 (65%) and L5-S1(31%). The mostcommon type of HNP was paramedian type (71%). 2. Focal protrusion of the posterior margin of disc and obliterationof epidural fat pad were observed in all of cases (100%) and other common findings were indentation of epiduralsac in 46 cases(96%) and compression of nerve root sleeve in 33 cases(69%). 3. Cephalad and caudad extension ofproturded soft tissue density in the spinal canal was observed in 15 cases (31%) with variable degree. And morethan 6mm extension were provided to be extruded disc in 9 cases. 4. Vacuum phenomenon was demonstrated in 5cases(10%) and was accompained with bulging annulus. 5. Forty eight herniated nucleus(HNP) were confirmedsurgically in 44 patients. Misinterpretations were made in 4 instances(4 patients); 1 because of lumbar scoliosis,1 because of spondylolisthesis, and the other 2 because of calcified posterior longitudinal ligament and bulgingannulus. One case of true negative examination was central and foraminal stenosis in spinal CT. Thus, sensitivity,specificity and overall accuracy of lumbar spine CT in HNP were 92%, 100% and 92%, respectively.

Congenital chylothorax is a rare disorder and can be diagnosed by prenatal ultrasonography recently. Most cases of congenital chylothorax were characterized by different clinical courses of respiratory distress. We describe two female cases with congenital chylothorax observed by ultra- sonography prenatally. In the first case, left-sided pleural effusion was noted by prenatal ultrasonography taken at 34 weeks of gestation, and then pleural fluid was extracted by intrauterine thoracentesis under sonography guidance. After birth, this patient was managed by TPN(total parentral nutrition) and intermittent thoracentesis without surgical treatment. But, pleural fluid was accumulated recurrently and respiratory distress was aggravated. At 15th hospital day, shock state was developed and patient died. In the second case, bilateral pleural effusion and ascites were noted by prenatal ultrasonography, and then patient was delivered immediately without intrauterine thoracentesis. After birth, the second case received conservative therapy including mechanical ventilation, TPN, intermittent thoracentesis and paracentesis. The patient was discharged with complete regression of chylothorax. We report the two cases with brief review of related literatures.

Heat stroke, a medical emergency, occurs when the body's thermal regulation is upset and unable to dissipate adequate amounts of heat with a rise in body temperature. It is characterized by hyperyrexia, with a core temperature of 40degrees C or more, hot dry skin, and central nervous system disturbance and usually results in rhabdomyolysis and multiorgan failure. Our case, a 43-year-old healthy male, was caused by a marathon, half course, on a sunny day in late summer. He suddenly fell down on the road and was delivered to a nearby hospital, where a seizure developed. He was transfered to our hospital and then displayed Central Nervous System disturbance, hot dry skin, acute liver failure, rhabdomyolysis, anuric acute renal failure, and disseminated intravasculular coagulopathy. He was treated with general supportive care and hemofiltration. Despite the aggressive management, he died of shock on the fifth day after admission.

Cimetidine, an H-histamine receptor antagonist, has been advocated to have enhancing effect on delayed type hypersensitivity. However, some recent reports have caused controversial opinion regarding the effect of cimetidine on delayed type hypersensitivity assessed in vivo. In this study the effect of cimetidine at the various periods of contact sersitivity reaction (CSR) to DNCB was assessed in guinea pigs. Three groups of five guinea pigs were sensitized with DNCB in the nuchal region and challenged with DNCB in the back on 16th day after sensitization, Cimetidine, 300mg/3ml/kg, was injected intraperitoneally once a day for the duration of different periods. For the first group, cimetidine was injected during the first 10 days after sensitization to assess its effect on the preparative and recognition phase of the induction period of CSR, For the second group, cimetidine was injected from the 6th to the 16th day to evaluate the enhancing effect of cimetidine on CSR at the period when suppressor T-cells were considered to be active. For the third group, cimetidine was injected for the last 3 days before elicitation test to assess the effect of short term treatment of cimetidine on the established CSR to DNCB. For the elicitation, two different consentrations of DNCB were applied on the three sites along both sides of the spine in the back. Total means of the degree of CSR elicited by DNCB were significanly ircreased by cimetidine in the second and third groups (p<0.05). These enhancing effects of cimetidine on CSR were more prominent at the uppermost back than other sites, eliclted by 0.05% DNCB rather than 0.01% DNCB.

OBJECTIVE AND METHODS: To determine correlations among ambulatory renin activity, ambulatory blood pressure and microalbumin excretion rate, 66 Korean essential hypertensives were studied after 4 week wash-out period. The ambulatory blood pressure was monitored every 30 minutes and mean BP were calculated automatically. Urinary microalbumin excretion rate(UAER) and ambulatory plasma renin activity(aPRA) collected at mid-day were measured by radioimmunoassays. Subjectives were divided into 2 groups by aPRA value(2ng/ml/hr). RESULT: 14 cases were high renin group and 52 cases low renin group. The mean BP were 148.83/94.69mmHg in low renin group, and 146.57/98.07mmHg in high-renin group without difference. UAER were not different also between both groups. 23.07%(4/14) of non-dippers were included in high renin group and 25.58%(12/52) in low renin group without statistical difference. The aPRA was significantly related to UAER and systolic and diastolic mean blood pressure. Also UAER was related significantly to day mean blood pressures. CONCLUSION: Thus aPRA is thought to be a meaningful indicator to predict hypertensive renal target organ damage as well as blood pressure measured with 24-hr ABPM.

Percutaneous tansluminal angioplasty(PTA) was done in 38-year-old female patient with membranous obstructionof IVC in the department of Radiology, Seoul National University Hospital. After PTA, pressure gradient between right atrium and IVC was relieved from 16mmHg to 6mmHg. The collateral circulation through hemiazygos vein andreflux into hepatic and right renal vein were disappeared. PTA is suggested to be an effective method in thetreatment of membranous obstruction of IVC.
