Hemangioma of the kidney is a relatively uncommon tumor, which is most commonly located in the tip of the papilla. This lesion is usually small and has been found incidentally at postmorten examination. About 200 cases of renal hemangioma have been reported since Virchow's original report in 1876. In renal hemangioma, cavernous hemangioma is the most common type. They can create diagnostic problem for the clinician and the radiologist. We experienced a case of renal cavernous hemangioma in the medulla of the upper pole. The patient was a twenty-seven-year-old male who had gross hematuria and right flank pain. A nephrectomy was performed. An ill-defined mass, 4.5x3.0x1.5 cm, was observed around the pelvis. Microscopically, the tumor mass was hemangioma of the cavernous type.

BACKGROUND/AIMS: Chronic hepatitis C virus (HCV) infection is often associated with extrahepatic autoimmune disease, and autoantibodies such as anti-nuclear antibody (ANA) or anti-smooth muscle antibody (ASA). The presence of autoantibodies may make discrimination between chronic hepatitis C with autoimmune features and type 1 autoimmune hepatitis difficult. We studied the prevalence of autoantibodies in patients with chronic HCV infection and their clinical significance. MATERIALS AND METHODS: ANA, ASA, anti-mitochondrial antibody (AMA), anti-microsomal antibody (AmA), rheumatoid factor (RF), anti-cardiolipin antibody (aCL) and lupus anti-coagulant (LA) were tested in 116 patients (80 chronic hepatitis C, 36 liver cirrhosis). Genotypes of HCV were determined in 25 patients by INNO LiPA. RESULTS: The overall prevalence of autoantibody was 65.5%. The most common autoantibody was aCL (34.5%), followed by ANA (25%), RF (18%), LA (15.5%), ASA (6.9%), anti-microsomal antibody (6%) and AMA (1%). The positive rate of either ANA or ASA was 30.2%, but both were positive in 1.7% only. There was no difference in the demographic features, biochemistry, HCV genotypes and disease status between autoantibody-positive and autoantibody-negative patients. CONCLUSIONS: Autoantibodies were commonly found in patients with chronic HCV infection. But, the presence of autoantibodies may be a non-specific finding in chronic hepatitis C infection without clinical significance.

Neurosarcoidosis without systemic manifestation is vary unusual condition. Solitary lesion in the spinal dura is exceptional. The diagnosis of the neurosarcoidosis is very difficult, because the efficacy of Kveim test is low in neurosarcoidosis. The histologic examination is considered as confirmative diagnostic tool. The authors reported a case of neurosarcoidosis involving the dura of the cervical spine, in a fifty-nine year old female who had suffered from mid-back pain for six months and paraparesis for two weeks. There was a dumbbell shaped mass in the D4-5 dura. It showed tan gray color with rubbery consistency. With histological examination, it revealed diffuse non-caseating granuloma. Occasionally asteroid bodies were observed within the cytoplasm of the multinucleated giant cells. After operation, she was treated with steroid, and she has been well about nine month period.

PURPOSE: To analyze and compare the immunohistochemical distributions of HO-1 and HO-2 with the developmental process of retina, focusing on the time of birth and opening eyes because it is the time of the exposure to hyperoxia and light exposure. METHODS: The retina of 16-day-old embryo, 18-day-old embryo, 20-day-old embryo and postnatal rats at 0 day, 5 days, 10 days, 15 days, 20 days, 1 month, 2 months, 3 months were examined by hematoxylineeosin staining and immunohistochemistry of HO-1 and HO-2. RESULTS: Similar distribution of HO-1 and HO-2 from embryo to mature retina were observed. It was observed that HO-1 and HO-2 was contained in ganglion cell layer, inner plexiform layer, inner nuclear layer, outer plexiform layer and pigment layer of the mature retina. In the developmental process, reactivity was observed in the cell body of ganglion cells after 0 day of its birth. The reactivity was increased after 5 days of its birth, staining was observed in nerve cell and nerve fiber of ganglion cell layer, inner plexiform layer, inner segment of neuroblastic layer, pigment layer at this time. Reactivity of ganglion cell layer and pigment layer was increased intensively after 15 days of its birth and weak reactivity in some of horizontal cells and amacrine cells in inner plexiform layer was observed. The same distribution as that of mature retina was observed after 20 days of its birth. CONCLUSIONS: HO-1 and HO-2 expression was temporally and spatially correlated with the normal development of retina in rats. HO was concerned with the structure and function of retinal development by the activation of its products and with anti-oxidant mechanism on the time of birth and opening eyes.

BACKGROUND: Induction of anesthesia with propofol commonly associated with reduction in systemic arterial pressure, especially in elderly and high risk patients. This reduction is influenced by the dose and rate of propofol injection. The aim of this study was to examine the effect of different injection rate of propofol on vital signs, dose requirement and induction time during induction period. METHODS: Unpremedicated one hundred and twenty ASA physical status I and II patients aged 20~60 years scheduled for elective surgery were randomly allocated into one of four (150, 300, 600, 1200 ml/hr) groups according to speed of injection of propofol during induction period. Loss of verbal contact was taken as the end-point of induction. Vital signs, SpO2, dose requirement of propofol and induction time were checked. RESULTS: As the injection rate of propofol became slower, there were significant reduction in induction dose and increase in induction time (p<0.05). For example, induction dose and time were 1.82 mg/kg, 223 +/- 58 sec in 150 ml/hr group and 3.14 mg/kg, 50 +/- 11 sec in 1200 ml/hr group, respectively. Also, decrease in systolic and diastolic pressure were less marked at lower injection rates. CONCLUSIONS: Slower injection of propofol produces less vital sign changes and dose requirement for the induction of anesthesia.

For the purpose of developing 'Web-Based Nutritional Education Program', this study analyzed nutritional problems of junior/senior high school students and set appropriate instructional goals for nutritional education program. Survey questionnaires were distributed from October 21,2002 to October 26, 2002 to a total of 564 students at three junior high schools and five senior high schools located in Seoul. The total number of questionnaires collected and used in our study was 479, which is 84.9% of the total questionnaires distributed. According to the survey results, three student groups (male and female students at junior high schools and female students at senior high schools) had lower than an ideal body weight. In case of their Basal Metabolic Indices (BMI), the female students and junior high school students showed a tendency to be underweight, while the other three student groups were within the normal range. The result of the survey showed that all four groups of students showed a deficiency in nutrient intake of calories, calcium and thiamin when compared with Korean RDA. Particularly, in the case of the female students at senior high schools, the deficiency of iron intake was a problem. The survey about food attitudes and food habits of the students showed that the senior high school students had more problems when compared with their junior high school counterparts (p < .001). Therefore, the instructional goals of nutritional education program were set as follows: 1) To improve the level of understanding and the perception of junior and senior high school students about the importance of a dietary lifestyle. 2) To change food attitudes and nutritional knowledge related to individual dietary 1ifestyle, so as to maintain good health through the enhancement of the students' physical activities. We found out that it is critically important to factor in the existing problems of food attitudes and food habits, as well as nutrient intake among junior and senor high school students when setting objectives for nutritional education programs.

Although varying types of cystic lesion, true to false, in the spinal cord have been described, spinal enterogenous cyst is a rare condition. It is considered as a result of congenital remnant of primitive foregut. The authors experienced a case of a spinal enterogenous cyst in the intradural space along the fouth, fifth and sixth cervical spine, occurred in a twenty-seven years old male patient. The cyst was composed of hyalinized fibrous wall with single layered lining epithelium, such as simple non-ciliated cuboidal epithelium or ciliated tall columnar epithelium with focal mucinous columnar epithelium.

STATEMENT OF PROBLEM: Many dental clinicians are concerned about immediate loading of inserted implants. However, there have been few clinical studies surveying the success rates of immediate loading, based on Korean implant systems. PURPOSE: The aim of this study was to evaluate the outcome of immediate functional loading of the implant (SinusQuick(TM) EB, Neobiotech Co., Seoul, Korea) in partially edentulous maxilla or mandible. MATERIAL AND METHODS: Total 15 implants were placed. Within 2 weeks after implant insertion, provisional implant-supported fixed partial dentures were delivered to the patients. Quantitatively, marginal bone loss was measured at the time of immediate loading, after 3-months of continued loading and at the last follow-up. The mean follow-up period was 4.8 months. RESULTS: Mean marginal bone loss from implant surgery to early loading, 3-months follow-up and last follow-up was 0.03 +/- 0.07 mm, 0.16 +/- 0.17 mm and 0.29 +/- 0.19 mm. No implant failed up to 6 months after insertion, resulting in a 100% survival rate. CONCLUSION: Immediate loading exhibited high success rate in partial edentulism for up to 6 months. Well-controlled long term clinical studies with large sample size are necessary to confirm this finding.

Suceinylcholine(SCC)-induced hyperkalemia due to mechanical neuromuscular defects sueh as burn, severe trauma, uremia, neuromuscular diseases and etc. is well recognized from 1950. The upper motor neuron diseases are categorized into these neuromuscular diseases. For cerebral palsy, one of the upper motor neuron diseases, there are many different opinions in hyperkalemia after the administration of SCC. To establish the effects of SCC on hyperkalemia, in children with cerebral palsy presenting for selective posterior rhizotomy under the monitoring of evoked EMG, serum potassium, sodium, calcium, chloride and creatine phosphokinase (CPK) were measured prior to, and 2, 5, 10 and 30 min after the administration of SCC. The results are as follows,; 1) The mean age and body weight in twenty patients were 4.4+/-1.4 years and 14.2+/-2.1 kg, respectively. 2) Fine fasciculation on the hand, 1 graded by Cullen, occurred only in five of twenty patients. 3) There is no significant increase in the concentrations of potassium (ranges of mean ; 4.16- 4.23 mEq/L) and CPK (ranges 2.43-295 mEq/L) with the administration of SCC until 30 min. . 4) No significant changes in sodium, calcium and chloride following SCC are revealed. In conclusion,succinylcholine does not produce an increase in plasma potassium in children with cerebral palsy. However, CPK levels trend to increase after the administration, even if there is no statistically significant difference in the levels at the different time sequences.
