Radioimmunoassay for the measurenment of plasma renin activity (PRA) was performed in 43 normal Koreans and 67 patients with essential hypertension. Urinary sodium excretion rates were measured in the concurrently collected 24 hour urine samples as an index of their sodium balance. The results were as follows: 1. There was an inverse correlation between 24 hour sodium excretion and PRA. The normal values of PRA in supine position ranged from 1.0 to 7.0 ng/ml/hr. When 24 hour sodium excretion were between 50 to 150 mEq. PRA in elderly persons tended to be low. 2. Of the 67 patients with essential hypertension, PRA was low in 20 cases (29.9%), normal in 36 (53.7%), and high in 11 cases (16.4%). 3. In the normal and high renin groups, who tended to be younger in ages, blood urea nitrogen was slightly higher than in low renin group, and hypertensive retinopathy was more prevalent in normal and high renin groups. 4. There were 17 cases with cardiovascular complications(12 with cerebrovascular accidents, 5 with heart failure): 6 in low renin group (30%), 9 in normal (25%) and 2 in high renin group (18.2%). There was no evidence that more frequent complications developed in higher renin groups.

This study was designed to investigate the effect of diazepam on the spontaneous contraction and oxytocin induced contraction of the isolated rat uterus. Female rat (Sprague-Dawley) pretreated with oophorectomy and 4 days administration of estrogen. Weighing about 200 g, was sacrificed by cervical dislocation, and the uteruses were isolated. A longitudinal muscle strip was placed in temperature controlled (37℃) muscle chamber containing Locke's solution and myographied isometrically. Diazepam inhibited the spontaneous contraction and oxytocin induced contraction of the isolated rat uterus in a concentration-dependent manner. GABA, muscimol, a GABA A receptor agonist, bicuculline, a competitive GABA A receptor antagonist, picrotoxin, a non competitive GABA A receptor antagonist, baclofen, a GABA B receptor agonist, and delta-aminovaleric acid, a GABA B receptor antagonist, did not affect on the spontaneous and oxytocin induced contraction of the isolated rat uterus. The inhibitory actions of diazepam on the spontaneous and oxytocin induced contraction were not affected by all the GABA receptor agonists and antagonists, but exceptionally potentiated by bicuculline. This potentiation-effect by bicuculline was not antagonized by muscumol. In normal calcium PSS, addition of calcium restored the spontaneous contraction preinhibited by diazepam and recovered the contractile of oxtrocin preinhibited by diazepam. A23187, a calcium inophore, enhanced the restoration of both the spontaneous and oxytocin induced contraction by addition of calcium. In calcium-free PSS, diazepam suppressed the restoration of spontaneous motility by addition of calcium but allowed the recovery of spontaneous motility to a considerable extent. Diazepam could not inhibit some development of contractility by oxytocin in calcium-free PSS, but inhibited the increase in contractility by subsequent addition of calcium. These results suggest that the inhibitory action of diazepam on the rat uterine motility does not depend on or related to GABA receptors and that diazepam inhibits the extracellular calcium influx to suppress the spontaneous and oxytocin induced contractilities.

One hundred and fifty two patients presenting with palpable primary breast cancer were studied to evaluate accuracy of clinical assessment, mammography, and ultrasonography in measuring tumor size. The clinical, mammographic, and ultasonographic diameter of tumor size was compared to histological diameters. The histological diameter of tumors was 27.9+/-12.7mm. The average diameter of tumor on clinical assessment was 33.8+/-13.1mm and its correlation coefficient to the histological size was 0.73. The average size on the mammography was 21.4+/-9.0m and its correlation coefficient to the histological size is 0.71. The tumor size on the ultrasonography in 22 patients was is 22.3+/-10.4mm. The sonographic measurement dimonstrated the highest correlation coefficient (0.83). The clinical assessment overstimated the tumor size, but the mammogaphic and sonographic measurement understimated it compared with histological size. The combined measurement with clinical and ultrasonography could be useful method to estimate tumor size preoperatively. And when it is combined with clinical assessment, it is the most reliable and accurate technique.

Purpose: To evaluate outcomes and complications after traumatic posterior hip fractures and dislocations classified according to the Thompson-Epstein system. Materials and Methods: Thirty-five cases were selected from among the patients we treated between January 2000 and December 2005. According to Thompson-Epstein classification, 5 cases were type I, 7 cases were type II, 5 cases were type III, 8 cases were type IV, and 10 cases were type V. The mean age at the time of injury was 41 years (range: 19~72 years). Twenty-six patients were men, and 9 patients were women. The mechanisms of injury included traffic accidents in 30 cases and falls in 5 cases. The mean follow-up period was 31 months (range: 13~86 months). Fracture reduction was achieved within 6 hours in 32 cases. Thirty-four patients underwent closed reduction, and 22 of these patients were treated using Allis'method. Results: All Thompson-Epstein type I fractures were managed with closed reduction. Two type II fractures were treated conservatively, and 4 were treated with open reduction and internal fixation. All 13 type III and IV fractures were treated using open reduction and internal fixation. Six type V fractures were treated conservatively, 4 were treated with open reduction and internal fixation, and 1 was treated using total hip arthroplasty. Posttraumatic arthritis was observed in 9 cases, 7 of which were Thompson-Epstein type IV. Avascular necrosis (AVN) of the femoral head and deep vein thrombosis were observed in 1 case. Sciatic nerve injury was seen in 5 cases. Conclusion: Complications often occur in Thompson-Epstein type IV fractures. We believe that early, appropriate anatomical reduction helps to improve outcomes.

OBJECTIVE: To assess the short-term clinical effect of a new spinal decompression device (DRX-3000) combined with transforaminal steroid injection (TFI) in comparison with TFI only in patients with lumbar herniated intervertebral disc (HIVD) METHOD: Fourty-one patients diagnosed as lumbar intervertebral disc herniation were recruited and divided into two therapeutic groups. Eighteen patients were treated with DRX-3000 combined with TFI. Twenty-three patients were treated with only TFI. The visual analogue scale (VAS), straight leg rasing test (SLR), radiating pain, Oswestry Disability Index (ODI), sitting tolerance, standing tolerance and sleeping tolerance were measured before treatment and 4 weeks after treatment. RESULTS: VAS, radiating pain, sitting tolerance and ODI were significantly improved after treatment in all patients (p<0.05). SLR and sleeping tolerance were significantly improved in combined treatment group and standing tolerance were significantly improved in TFI group after treatment (p<0.05). After treatment, degree of VAS decrease was larger in combined treatment group than TFI group(p<0.05). CONCLUSION: Spinal decompression with TFI was more effective than only TFI in patients with lumbar HIVD in a short period.

PURPOSE: This is to examine the neurodevelopmental outcomes of very low birth weight (VLBW) infants by Korean infant developmental screening test. METHODS: 29 VLBW infants and 39 normal term infants, at their corrected age of 1 to 3 years, were included for the study. Risk factors which influence neurodevelopmental outcomes were analyzed. RESULT: The mean levels of developmental quotients for VLBW infants were lower than those of term infants (P<0.001); gross motor 99.3+/-27.28 vs. 121.3+/-19.08, fine motor 95.9+/-27.22 vs. 118.3+/-17.77, social-personality 100.2+/-28.01 vs. 126.3+/-21.31, language 99.5+/-27.34 vs. 120.1+/-18.82, cognitive-adaptive 101.4+/-28.60 vs. 122.7+/-19.59, and total developmental quotient is 99.3+/-27 vs. 121.7+/-19.18. Nevertheless, the mean levels of the individual developmental quotients for VLBW infants were in normal range. There were five VLBW infants (17%) those who scored lower than 80, also showed neurologic sequelae. The infants who had the more risk factors during hospitalization scored the less developmental quotient (R(2)=0.35, P=0.01). CONCLUSION: Although the mean levels of the individual developmental quotient for VLBW infants, assessed by Korean infant developmental screening test, were lower than those of term infants, they are in normal range.

PURPOSE: The purpose of this study is to analyze the results of intertrochanteric fractures treatment with proximal femoral nail antirotation (PFNA) without using fracture tables and thereby prevent complications. MATERIALS AND METHODS: Forty cases of intertrochanteric fracture of 39 patients that were treated with PFNA without using fracture tables between January 2008 to December 2009 were analyzed. There were 13 males and 27 females. The mean age was 76 years old. Using AO classification, 6 cases were A1, 25 cases were A2 and 9 cases were A3. The operation was done without using fracture tables at supine position. Operation time, intraoperative bleeding were checked. For the result, Cleveland index, tip apex distance, fracture site sliding rate, change of femur neck and shaft angle were evaluated. Bone union time and complications were also estimated from the follow up radiograph. Statistics were analyzed using Independent T-test. RESULTS: The mean operation time was 40 minutes (25 to 70 minutes) and mean intraoperative bleeding was 113 cc (40 to 250 cc). The Cleveland index was shown 94% of 5, 6, 8 and 9 zone, the tip apex distance was 12.96 mm (6 to 22 mm), the fracture sliding distance was 1.9 mm (0 to 6 mm), the change of femur neck and shaft angle was 2.5 degree (0~10 degree) and the average bone union time was 15 weeks (8 to 24 weeks). The complication include 2 cases of delayed union and 2 cases of varus deformities. CONCLUSION: We have shortened the operation time by closed reduction methods without using the fracture tables, and the complication were minimized with using simple tools like a reduction forcep or bone hook at PFNA blade insertion.

Primary cardiac lymphoma (PCL) is an extremely rare and fatal neoplasm of the heart. Traditionally, it is defined as lymphoma involving the heart or pericardium. PCL has a poor prognosis because of the diagnostic difficulty and its location. We present the case of a 48-year-old man who presented with pericardial effusion and diffuse cardiac wall thickening. We first suspected infiltrative heart disease. However, even after performing a biopsy, we could not establish an accurate diagnosis. After 20 months, primary cardiac diffuse large B cell lymphoma (DLBCL) was diagnosed by cervical lymph node biopsy. In this case, after chemotherapy, the DLBCL lesions, including cardiac wall thickening, improved. The treatment outcome suggests that the diagnosis was diffuse infiltrative PCL with delayed extracardiac involvement.
