The results of alpha-acetyldigoxin(Dioxanin(R)) administration in 21 patients with congestive heart failure were as follows. Alpha-acetyldigoxin is a new oral preparation of cardiac glycoside derived from lanatosid C. 1. For rapid digitalization in 2-3 days, the initial dose was 1.2 to 2.6mg (average 1.96mg). For medium-fast digitalization in 4 days, the loading dose was 2.0 to 3.2mg (average 2.7mg). For slow digitalization 0.1 to 0.4mg was required for 5 to 6 days without loading dose. The maintenance dose was 0.1 to 0.4mg (average 0.33mg) daily. 2. The therapeutic effect of acetyldigoxin was excellent in 15 cases (71%), good in 4 cases (20%) and stationary in 2 cases (9%). 3. Side effects were observed in 2 cases with usual dosage regimen. One accidental case who took single dose of 4mg(20 tablests) developed supraventricular tachycardia with varying degree of atrioventricular block, ventricular bigeminy and premature beat but recovered completely after 6 days.

INTRODUCTION: Bone mineral density (BMD) is an important index in diagnosis of osteoporosis and other metabolic bone diseases, prediction of fractures, and monitoring treatment. This study was to find a more feasible technique for prediction of osteoporotic fracture between dual energy X-ray absorptiometry (DXA) and quantitative computed tomography (QCT) and to reveal the actual change of bone strength when BMD was changed. METHODS: Ten of these 20 specimens were used as the demineralized group and the other 10 as the control. Each specimen was immersed in HCl solution at for a period of at least 10 minutes, up to 100 minutes, at an interval of 10 minutes for different levels of demineralization. BMD was measured using DXA and QCT. Uniaxial compression tests were conducted to measure biomechanical parameters. Pearson correlation analysis was used respectively between BMD and biomechanical parameters and between DXA and QCT. RESULTS: Elastic modulus (r=0.87) and yield stress (r=0.84) showed a statistically significant correlation with DXA BMD. Through correlation analysis with QCT BMD and elastic modulus, correlation coefficient showed hemi-vertebra (r=0.80) and trabecular (r=0.68). In yield stress, there was a statistically significant correlation in hemi-vertebra (r=0.87) and trabecular bone (r=0.84). CONCLUSION: DXA is a current standard technique not only for diagnosis of osteoporosis but also for prediction of fracture risk compared to QCT. Actual decrease of bone strength was much greater than that of BMD by both DXA and QCT.

The common errors in preoperative treatment plan for the orthognathic surgery can be occurred during cast impression, cast mounting procedure with face-bow transfer, surgical stent fabrication, and so on. One of the most common errors exists during mounting process of the model on the articulator. Accurate mounting of dental casts to articulator should be achieved by transferring the 3- dimensional spatial relationship of the maxillary arch to an articulator. A face-bow is used for transfer this relationship to articulator, usually by relating the face-bow to a plane of reference of maxillary cast. The purpose of this study is evaluation of the accuracy of face-bow transferring of maxillary model to the articulator. The maxillary casts of thirty patients for orthognathic surgery were mounted on articulator with an face-bow instrument. The relationship of occlusal plane angle to Frankfort horizontal plane relations were compared the cephalogram with the cast-mounted articulator. As a result of this study, the significant difference between the maxillary occlusal planes angle in the cephalogram and articulator were found . The results were followed,1. The mean occlusal plane angle in cast-mounted articulator was 13.5.(SD+/-5.4).2. The mean occlusal plane angle in cephalogram was 10.4.(SD+/-4.3).3. The mean difference of occlusal plane angle between cast-mounted articulator and cephalogram was 3.3.(SD+/-4.6).According to the result, we should suggest that the occlusal plane angle to Frankfort plane in cast-mounted articulator is more steeper than that of cephalogram.And then, maxillofacial surgeon should try to get a more predictable result by suggesting the proper correction method and mounting the cast accurately.

Intramedullary myelitis due to bacterial meningitis associated with cervical epidural abscess is very rare. Its cause and clinical features are non-specific, therefore exact diagnosis is often missed or mistaken for other disease and immediate treatment may be delayed. We report a case of intramedullary myelitis due to epidural abscess presented with prominent symptoms of meningitis and manifestations of acute cerebrovacular accident. A 69 -year-old man was admitted due to right hemicranial headache with pain on right posterior neck and febrile sensation. At first, the patient's headache was improved by conservative therapy. Three weeks later, the patient showed abrupt right hemiparesis (MRC grade 2/5) with drowsy mentality. The CSF findings of the patient were compatible with acute bacterial meningitis. Cervical spine MRI showed cervical epidural abscess and extensive intramedullary myelitis from cervical to lumbar spinal cord. After antibiotic therapy, mentality of the patient became to be alert and right hemiparesis was improved to MRC grade 4/5. Follow up cervical spine MRI after several weeks represented that the lesions of cervical epidural abscess and intramedullary myelitis were significantly diminished.

Voltage dependent calcium channels mediate wide variety of physiological functions including neurotransmitter release, neurite outgrowth, and gene expression in neurons. omega-Conotoxin-sensitive N-type calcium channels are exclusively expressed in nervous system and involved in the control of neurotransmitter release from neurons. In this experiment, I have investigated human chromosomal location and rat neuronal distribution of N-type voltage dependent calcium channel alpha1, subunit [alpha1B]. I have localized human alpha1B subunit gene to the long arm of chromosome 9[9q34] by fluorescent in situ hybridization. The distribution of rat alphaB1 subunit mRNA has been examined in the rat brain by in situ hybridization histochemistry and high level of alpha1B subunit mRNA has been observed in olfactory bulb, anterior olfactory nucleus, cerebral cortex, piriform cortex, hippocampus, dentate gyrus, parabrachial nucleus, and cerebellum and low level of expression was also found in other areas of rat brain.

PURPOSE: Liver transplantation (LT) is regarded as an important management option for fulminant hepatitis (FH), which is associated with considerable mortality under conservative management. The aim of this study was to evaluate the outcome of children with FH according to management. METHODS: We reviewed medical records of patients presented with FH from January 1994 until April 1999. The children were grouped according to the treatment. Group A was classified for supportive treatment only and group B for supportive treatment plus LT. Children were considered as candidates for LT if the level of factor V decreased to below 20% of normal or the patient's condition deteriorated despite intensive care during the initial 48 hours. Underlying disease, duration after jaundice, grade of encephalopathy, laboratory findings, treatment and outcomes were analyzed. RESULTS: The study group comprised 7 females and 8 males aged from 8 months to 15 years old (median age of 4 years). The causes of FH were Wilson disease (4 cases), Epstein-Barr virus infection (1 case), drug (1 case) and idiopathic (9 cases). There were 5 children in group A and 10 in group B, and there were no significant differences in age, sex ratio, underlying diseases, grade of hepatic encephalopathy and laboratory findings between the two groups. One out of 5 in group A and 9 out of 10 in group B survived. But all the children in group A who met the criteria for LT and received only supportive care died. One out of 10 in group B died because of grade IVa hepatic encephalopathy which advanced to brainstem herniation. CONCLUSION: This study showed that patients who were managed with supportive care only, although LT was indicated, died and that 9 out of 10 who received LT survived. Therefore, we suggest LT should be considered in the management of FH.

BACKGROUND: In 1951, Ardran reported that metastatic bone lesions could be detectable on plain radiography with 30% to 50% of decalcification. Authors performed experimental study for minimum level of decalcification to detect the osteolytic bone metastasis of long bone with recent technique of radiographs. METHODS: One pair of fibula and humerus from two cadavers was cut into specimen 1 inch in length. Distal half of specimen was dipped into hydrochloride (HCl) with 15 min interval. All 16 specimens were checked by film-type radiography (FR), computed radiography (CR), digital radiography (DR). To exclude inter-observer's variance, 3 radiologists evaluated images. Calcium amount before and after decalcification was measured and expressed in percentage of decalcification. RESULTS: Osteolytic changes were detectable with 11% to 16% of decalcification for fibula and 3% to 8% for humerus on plain radiography with FR, CR, and DR. CONCLUSIONS: Our study showed that minimum of 3% and maximum of 16% of decalcification is necessary when osteolytic metastatic bone lesions of long bone could be detected on plain radiography.
