Central serous chorioretinopathy is a disease which causes decreased visual acuity and functional disturbance. As the subretinal fluid is absorbed, the visual acuity is improved but patient's complaint such as metamorphosia is remained. To assess the recovery of visual functional disturbance in response to absorption of the fluid, the hue discrimination and contrast sensitivity were tested in central serous retinopathy patients (N=30) at the first visit, first visit after the absorption of subretinal fluid, and final visit. At the first visit, there were stastically significant differences in the mean square root of total error score, blue-yellow and red-green partial error score between normal control group and central serous retinopathy group and stastically significant differences in all spatial frequency between normal group and central serous retinopathy group. First visit after the absorption of subretinal fluid, and final visit, there were stastically significant differences in the mean square root of total error score, blue-yellow and red-green partial error score between normal control group and central serous retinopathy group and stastically significant differences in mid-high spatial frequency between normal group and central serous retinopathy group.

BACKGROUND/AIMS: Gastric carcinoma is the most common malignant neoplasm in Korea and is known to be associated with intestinal metaplasia (IM) of gastric epithelium, of which type III IM is suggested to play a special role in the carcinogenesis. This study is to evaluate the subtypes of IM and to measure each subtype in chronic gastritis. Methods: From October 1997 to September 1999, 321 patients with endoscopic chronic gastritis were evaluated the grade of chronic gastritis and IM by histologic and histochemical stain. RESULTS: Chronic inflammation and IM were remarkably severe in men and Helicobacter pylori (H. pylori) positivity was 69.4% in men and 65.2% in women. The frequency of IM was 50.1%, of which 65.4% was in men and 34.6% in women. The frequency of IM subtypes was 43.2%, 11.7% and 45.1% for type I, II and III respectively. Sixty percent of IM was noted in more than 50 years of age and ninety percent in more than 40 years of age. The frequency of type III IM was 61.6% in men and 38.4% in women. Sixty one percent of type III IM was noted in more than 50 years of age and ninety percent in more than 40 years of age. Interestingly, fifty three percent of type III IM was noted in men more than 40 years of age. The prevalence of H. pylori infection in type III IM was similar to in type I and II. The glandular atrophy in type III IM was remarkably severe than that in type I and II. Conclusions: The results of this study show that the proportion of type III IM in chronic gastiritis is remarkably high in Korean and age and sex distribution is similar to that of gastric carcinoma.

The result of artificial skins made with collagen is poor after grafting over the full thickness wounds due to their rapid degradation by enzymatic cleavage. This study is an in vivo study of an artificial skin made with a biodegradable polymer, which can better address the problem of the collagenous artificial dermis. To investigate the availability of a biodegradable polymer for an artificial dermis and to get an information about the optimal degradation rate of a polymer for an artificial dermis, we made an artificial dermis by seeding of fibroblasts within the vicryl mesh and made a bilayer artificial skin by covering the artificial dermis with cultured keratinocytes. And these artificial dermis and artificial skin were evaluated in a full thickness wound model. The results are as followings: 1. The artificial dermis was available for grafting for 1 week culture of vicryl mesh-fibroblast. 2. The artificial dermis retarded the contraction of full thickness wounds. 3. The artificial dermis generated the granulation tissue and accepted the STSG completely. 4. The generated tissue from the artificial dermis had incorporated into the surrounding tissue by 4 weeks postgrafting. 5. Vicryl in the artificial dermis became to biodegrade from the culture period and absorbed completely by 5 weeks. 6. The epidermal portion was poorly differntiated during in vitro culture period. In conclusion, the polymer-fibroblast graft can retard the wound contraction and generate a new tissue permitting a useful dermal replacement. And to get more optimal results, another polymer which has slower biodegradation rate than vicryl should be used for the artificial dermis and the epidermal portion should be differentiated after in vivo grafting.

Necrotizing fasciitis, an uncommon, often fulminant bacterial infection, rarely originates in the chest wall. Although it can occur in any region of the body, the abdominal wall, perineum, and extremities are the most common sites of infection. It is characterized by wide spread fascial necrosis with relative sparing of skin and underlying muscle. Diagnosis is often extremely difficult and relies on a high index of suspicion. Prompt surgical intervention is essential. We experienced a patient with idiopathic necrotizing fasciitis in the chest wall and reported with brief review of literature.

Two cases of acute digitalis poisoning were presented. The first patient was 20-year-old male with asymptomatic ventricular septal defect (maladie de Roger) who attempted suicide by ingestion of degitalis leaf about 6.0 g (60 tablets). He developed severe epigastric pain and vomiting one hour after ingestion. Syncopal attack was developed once for a few minutes and recovered. Electrocardiogram revealed 2:1 A-V block. By conservative management he was recovered. The second patient was 2-year-old, healthy baby who ingested digoxin about 2.5 mg(10 tablets) by accident. He developed severe vomiting and electrocardiogram revealed 1degrees, 2degreesand 3degrees A-V block in series. He was recovered by conservative management without sequele.

OBJECTIVES: Radiofrequency(RF) ablation is an effective and low risk curative treatment for supraventricular arrhythmias. Catheter ablation produced cardiac lesions primarily through formation of coagulation necrosis. We evaluated the degree of myocardial injury after RF catheter ablation by means of serial measurement of myocardial enzyme. METHODS: Fifty-one patients with symptomatic supraventricular tachycardia were included. There were 32 men and 19 women(mean age. 39.5+/-15.4 years)All patients underwent electrophysiologic study to detect accessary pathway and ablation with radiofreguency current. A mean of 18.3+/-14.2 radiofrequency pulses were delivered. The pulses were at a power of 50 to 60 Volts for a duration of 20 to 30 seconds. Unipolar method and a 6F or 7F catheter with a 4 mm tip electrode was used. LDH, CPK and Ck-MB as a kind of cardiac enzyme were measured before and after ablation. RESULTS: 1) The concentration of LDH and CPK were elecated at 8 hours and 16 hours after ablation (p<0.05). 2) The concentration of CK-MB was elevated at 8 hours, 16 hours, 24 hours and 72 hours after ablation(p<0.05). 3) There was no correlation between the number of applications and amounts of radiofrequency current and rise in LDH, CPK, CK-MB concentration. CONCLUSION: The concentration of LDH, CPK and CK-MB were elevated after ablation but they were within normal limits. RF catheter ablation produced myocardial damage inevitably but were within normal limits. RF catheter ablation produced myocardial damage inevitably but minimally, then RF ablation is an effective and safe therapeutic modality for patients with symptomatic tachyarrhythmias.
