BACKGROUND: According to the 1992 version of ACLS guideline, adenosine is recommended as the first line drug far the treatment of paroxysmal supraventricular tachycardia(PSYT). But adenosine is not used frequently in our country, despite currency proven effect and safety. Therefore we tried to compare the efficacy and safety of adenosine with verapamil for the treatment far PSVT. MATERIALS AND METHODS: We prospectively reviewed charles of PSVT patients admitted to YongDong Severance Hospital from Jan. 1995 to Dec. 1996. These patients were randomly divided into two groups. The flat group was given 6mg of adenosine initially, and another 12mg was given within 5 minutes if fast dose failed. The other group was given 5mg of verapamil initially, and if failed, 10mg was given within 10 minutes. The results were analyzed by Chi-square test and student-t method. RESULTS: In converting PSVT to normal rhythm, adenosine and verapamil showed similar results and there was no difference between the two Groups in frequency of side elects, but serious arrhythmia such as ventricular fibrillation and ventricular tachycardia was not seen in the adenosine group. CONCLUSION: Adenosine not only showed comparable effect and safety, but also had shorter action time than verapamil. Therefore we recommand adenosine, as a safe and effective fort line drug for PSVT.

The role of GABA or glycine as an inhibitory neurotransmitter is well established, and GABAergic or glycinergic neurons appear to play an important role in the mammalian retinas. It has been reported that certain amacrine, bipolar, displaced amacrine and ganglion cells are consistently labeled with anti-GABA or anti-glycine antisera in the mammalian retinae so far, and it has been suggested that colocalization of GABA and glycine within the retinal neurons could be common in the mammalian retina by recent immunecytochemical and electrophysiological studies. This study was conducted to localize GABAergic and glycinergic neurons and to define whether GABA and glycine are colocalized within same retinal neurons of the rat retina by immunocytochemical method using anti-GABA and anti-glycine antisera. The results were as follows : 1. GABAergic neurons of the rat retina were amacrine, interplexiform, bipolar, displaced amacrine and ganglion cells, and processes of GABAergic neurons formed dense networks with distinct two bands in the inner plexiform layer. 2. Glycinergic neurons were amacrine, bipolar, displaced amacrine and ganglion cells,and their processes were evenly distributed as dense networks through whole inner plexiform layer. 3. 28.5% of GABA immunoreactive amacrine cells and 9.8% of GABA immunoreactive bipolar cells located in the inner nuclear layer,and 11.9% of labeled neurons located in the ganglion cell layer showed glycine immunoreactivity in the rat retina. These results demonstrate that GABA and glycine, major inhibitory neurotransmitters, are colocalized within certain amacrine and displaced amacrine cells, and a few bipolar cells, and that neurons synthesizing and utilizing both GABA and glycine as their neurotransmitters may play an unique role in the visual processing in the rat retina.

The goals of hip arthroplasty have been to eliminate pain, decrease deformity, increase morbility and obtain stabiIity. Currently total hip replacement is the best avaliable procedure to accomplish these goals. A prospective study of total hip arthroplasty was begun at the orthopedic dept of Kyung Hee Medical College in 1974. Between May, 1974 and June, 1977. 69 total hip replacements of the Charnley type, the Trapesoidal-28 type and the Muller type were peformed by the authors. Of the 60 Patients involved in this study, 9 had bilateral operations. The Charnley type Prosthetic device was used in 56 cases, the Trapesoidal-28 type in 7 cases and the Muller type in 6 cases. Complications included wire breakage, dislocation, loosening, femur shaft perforation, nonunion of greater-trochanter, acetabular protrusion, transient femoral nerve palsy, femur shaft fracture, infection, socket lateralization, ectopic bone formation and death. In 59 patients of the 60 patients, 53 patients felt that they were definitely improved, 5 patients felt their condition was unchanged and 1 patient felt her condition was worse.

Respiratory syncytial virus (RSV) is the major cause of lower respiratory tract infection in infants. Life-threatening RSV infection is often reported in young children and immunocompromised hosts. Since there is no report on ribavirin therapy for RSV pneumonia in pediatric cancer patients in Korea, we report one case of RSV pneumonia that developed in an infant with acute lymphoblastic leukemia (ALL). Despite administration of oral ribavirin and intravenous immunoglobulin, the patient's respiratory distress worsened and admission to an intensive care unit was necessary. Chest x-ray showed multifocal consolidation, pneumothorax, and pneumomediastinum. Treatment with aerosolized ribavirin led to significant clinical improvement. The role of aerosolized ribavirin is still controversial, but it might have a therapeutic potential for severe RSV pneumonia in children with leukemia.

Pseudoxanthoma elasticum is a rare, heritable disorder of elastic fibers characterized by yellowish, coalescing papules on the loose and wrinkled flexural skin. An 18-year-old man presented cutis laxa-like marked wrinkling on the axillae, trunk and thighs for about 10 years. There was no similar skin lesion on his family members and no other systemic involvement was found. Histopathological examination of the abdomen revealed fragmentation and calcification of elastic fibers in the middle and lower dermis. Von Kossa staining showed calcium deposition along the altered elastic fibers. Herein, we report a rare case of autosomal recessive pseudoxanthoma elasticum presenting generalized cutaneous laxity.

A 28-year-old woman presented with multiple, asymptomatic, erythematous to bluish papules located on the chest. Histopathologically, three round, well defined cystic structures were seen on the upper and lower dermis. The first cyst was milia, the second was apocrine hidrocystoma and the other, largest cyst was an eruptive vellus hair cyst (EVHC). A diagnosis of multiple pilosebaceous cysts combined with apocrine hidrocystoma was made. Since the milia and EVHC originate from the pilosebaceous unit, and the apocrine duct opens to the pilosebaceous orifice, we suggest that they can occur simultaneously in the same unit.
