Carotid endarterectomy is superior to medical treatment in preventing secondary stroke in patients with symptomatic high grade carotid stenosis. Transluminal angioplasty is a promising procedure as an alternative treatment for these patients. We report two cases of carotid angioplasty with Palmaz-Schatz stent in patients with carotid artery occlusive disease. One patient presented with decreased right visual acuity because of retinal arterial embolism. The angiogram demonstrated a discrete tight stenosis of right internal carotid artery carotid stenting with Palmaz-Schatz coronary stent was performed without any significant complications. The other patient presented with recurrent episodes of cerebral infarction, for which he had undergone left carotid erdarterectomy 3-years ago. The carotid angiogram demonstrated tight stenoses of both internal carotid arteries. Carotid artery stenting was performed at left and right internal carotid arteries without any complications. We suggest that stenting may be an effective and safe therapeutic alternative to surgical treatment in some selected patients with carotid artery occlusive disease.

A study was made of the differences in clinical features and immunological aspects between herpes zoster patients with malignancies and those without malignant tumors. The results obtained from the retrospective review of medical records are as follows: Herpes zoster occurred more frequently in younger patients(less than twenty) with malignanciee as compared with the control group of the same ages,' Male was dominant among zoster patients with malignancies as is the contrary to contral group; Tihere were no marked differences in primarilly involved dermatomes between the two groups; Generalized varicelliform eruptiona were more common in zoster pa,tients with malignaneies than in control group, It seemed that zoster patients with malignancies complained of milder degree of pain. Zoeter patienta associated with malignancies were more frequently DNCB-negative and had decreased OKT3+ pan T cells, OKT4+ helper/inducer T cells as compared with control group, which suggest impaired cell mediated immunity in the former.

Intraventricular hemorrhage is a common hemorrhagic cerebral disorder in premature, but occurs much less frequently in the full-term newborn. In order to obtain documentation of clinical and ultrasonographic characteristics of intraventricular hemorrhage in full-term, we performed cerebral ultrasonography on 602 newborn infants who had been admitted to neonatal intensive care unit at the Deppartment of Pediatrics, Yonsei University College of Medicine between December 1989 and June 1991. 15 cases (2.5%) of intraventricular hemorrhage were analysed. The results were as follows: 1) Among 15 cases with intraventricular hemorrhage, there was no obstetrical and perinatal complication in 8 cases (53%) and 13 cases (87%) were neurologically normal at birth. 2) Sudden onset of dramatic neurologic abnormalitis inclued seizures, fever, bulging fontanel, irritability, lethargy, vomiting in cases (73%) and the remainder (27%) had no clinical symptoms and signs. 3) The age at diangosis of hemorrhage was before 72 hours in 5 cases (33%), between 4 and 7 days in 2 cases (13%), at 8 to 28 days in 8 cases (53%), 8 of 15 cases (53%) had Grade 1 IVH, four with Grade 2, cases with Grade 3, and 1 case of these infant demonstrated Grade IV IVH. The source of hemorrhage was subependymal germinal matrix in 12 cases (80%) and choroid plaxus in 3 cases (20%). 4) Precipitating factors were cerebral venous infarction in 7 cases, hypoxic injury in 5, and 3 other infants had no identifiable medical risk factors. 5) Among all 15 survivors, 2 of 3 infants with choroid plexus hemorrhage required placement of a ventriculo-peritoneal shunt, in the other case, ventriculomegaly decreased spontaneously.

BACKGROUND/AIMS: This study was aimed to examine if FB1 induced-hepatotoxicity involves apoptosis, and cholesteryl hemisuccinate (CS) pre-treatment would selectively interfere with FB1 induced-apoptosis of hepatocytes. METHODS: Sprague-Dawley rats were intravenousely injected with FB1 (1.25 mg/kg/day) for two days, and were sacrificed at 3, 6, 12, 24 and 48 hours after injection. Another experiment group was composed of rats with pretreatment of CS (100 mg/kg/day, i.p.) before FB1 injection. RESULTS: This study demonstrated that administration of hepatotoxic dose of FB1 to Sprague-Dawley rats resulted in liver injury leading to cell death by apoptosis. FB1-induced apoptosis was preceded by early elevation in serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), total cholesterol, and appearance of injured pre-apoptotic cells at 12 hours was followed by massive fragmentation and margination of heterochromatin at 24 hours. CS pre-treatment prior to FB1 injection ameliorated serum biochemistry and hepatic injury with apoptosis, demonstrated by histological, ultrastructural and TUNEL (terminal deoxyribonucleotidyl transferase-mediated dUTP-digoxigenin nick end labeling) methods. In addition, there was remarkable decrease in number of PCNA (proliferative cell nuclear antigen)-positive proliferating hepatocytes compared to that of FB1 treated group. CONCLUSION: This study suggests that apoptosis significantly contributes to FB1-induced hepatotoxicity in vivo, and pre-exposure of rat to CS prevents FB1-induced hepatic apoptosis and proliferation.

There is much controversy concerning the method of treatment on the tibial fracture because of frequent complications, such as non-union, delayed union and infection. Authors reviewed and analyzed 110 tibial fractures which had been treated at the Department of Orthopedic Surgery, Sung Ae General Hospital from June 1983 to March 1987 by the groups, conservative treatment, open reduction and internal fixation with compression plate and closed flexible intramedullary nailing. The results were as follows :1. In regard to the fracture location, there was no difference in the healing time among the treatment methods. The I.M. nailing group healed 1.5 weeks earlier than other groups in each location. 2. In minor and moderate severity by Ellis, the I.M. nailing group revealed better result, and in major one, the compression plate group showed better result. More complications occured in major severity. 3. Union time among the trestment methods was not affected by the fibular fractures, but most of the complications occured in the concomitant fibular fracture case. 4. In open fracture, the healing time showed no difference among the groups, and was prolonged about 2 weeks than closed fracture. In closed case, the I.M. nailing group showed good result. 5. The cases, which were reduced earlier in the conservative group, and treated within 3 days in the I.M. nailing group revesled better result. 6. The radiological union time from the definite treatment was 15.80 weeks in the conservative treatment group, 15.18 weeks in the compression plate group and 13.92 weeks in the I.M. nailing group.

Purpose: This study was aimed to identify the effect of taping applied to both hamstring on the horizontal velocity of the center of mass (COM) and the angle and peak angular velocity of the knee and hip joints in the sagittal plane during the crouching start. Methods: Seven elite sprinters (three male 100-m sprinters and four male 400-m sprinters) who enrolled in Korea National Sport University and placed in the National Sports Festival participated in this study. The crouching start is divided into four separate phases by the five events: set position (E1), rear block exit (E2), initial contact of rear leg (E3), take-off of rear leg (E4), and initial contact of front leg (E5). The angle (°) of knee and hip joints in each event and the velocity of COM (m/sec) and peak angular velocity (°/sec) in each phase were analyzed before and after the application of kinesiology taping (KT) on both hamstring and placebo taping (PT). Results: There were no significant differences in the velocity of COM and the angle and peak angular velocity of knee joint among the taping conditions. In 400-m sprinters, the front hip joint with KT or PT flexed less than without taping at E1 (p=0.039), E4 (p=0.018), and E5 (p=0.018). Also, during the phase from E1 to E2, the rear hip joint with both KT and PT extended at lower angular velocity compared to without taping (p=0.018). Conclusion While taping may be a beneficial practice for elite sports performance, the application of KT on both hamstring does not enhance sprinters’ start performance.
