BACKGROUND AND OBJECTIVES: The development of coronary intervention registry system is required for analysis of current status and more efficient management of patients with coronary artery disease in Korea. We developed database system and registry system in internet environment to confirm the possibility of nationwide system construction and of useful information providing on coronary intervention. MATERIALS AND METHOD: Database for coronary intervention and web-based registry system were developed and installed on internet server. Data elements consist of demographics, coronary risk factors, initial diagnosis, lesion characteristics, type of interventional procedures, and post-procedure outcomes. RESULTS: Total 734 patients were registed by 12 intervention centers from November 1998 to October 1999. Patients with angina pectoris and myocardial infarction were 78.5% and 21.5%, respectively and 14.6% of all patients had history of previous coronary intervention. Major coronary risk factors of the patients were smoking (38.6%), hypertension (33.8%), and diabetes (18.0%). Proportions of the patients with single-vessel disease, two-vessel disease, and triple-vessel disease were 64.7%, 26.2%, and 9.1%, respectively. Left main disease was detected in 2.0%. Balloon PTCA only was performed in 209 patients and 530 patients underwent coronary stent insertion. CONCLUSION: Multicenter data of coronary intervention were collected via internet-based system, and it was possible to construct intervention database. These web-based systems linked with database will provide status of Korean interventional procedures and be able to support multicenter study efficiently by expanding the participating hospitals and including more detailed database fields.

In order to evaluate the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in terminally failing hearts, we screened the explanted hearts of transplantation recipients for the presence of HBV DNA and HCV RNA. DNA and RNA extractions were taken from explanted failing hearts (N=7) and normal hearts (N=). Polymerase chain reaction (PCR) and in situ PCR of HBV or reverse transcription-polymerase chain reaction (RT-PCR) and in situ RT-PCR of HCV were performed. The positivity of HBV in failing hearts was 63% (17/27) and it was 50% (3/6) in normal hearts in PCR. There was no significant difference in the positivity of HBV DNA between failing and normal hearts. The positivity of HCV in failing hearts was 18.5% (5/27) and it was 16.7% (1/6) in normal hearts in nested RT-PCR. There was no significant difference in the positivity of HCV RNA between failing and normal hearts. HCV was very rarely observed in explanted terminally failing hearts and HBV was frequently found in both explanted failing hearts and normal hearts. We concluded that these viruses have little direct causal relationship with the development of heart failure.

BACKGROUND: Angiotensin convertiong enzyme inhibitors have been shown to exert favorable effects on the left ventricular remodeling process associated with ventricular dilation after coronary occlusion. However, the effects of such therapy on global and regional left ventricular remodeling after coronart artery reperfusion have not been characterized, nor have such effects been assessed after exercise training. METHODS AND RESULTS: Female Sprague-Dawley rats(n=80) were randodmized into 4 groups at 5 days after 45 minutes of left coronary artery occlusion followed by reperfusion. Animals completion the experiment included : Untreated Sedentary group(n=20), Untreated with Swimming Exercise group(n=21), Captopril Treated Sedentary group(n=18) and Captoril Treated with Exercise group(n=21). At 3 weeks after randomization, global and regional morphologic changes of the left ventricle(LV) were examined from mid-ventricular transverse slices which were perfusion-fixed at a constant aortic pressure of 60mmHg and a left ventricular cavity pressure of 10mmHG. At rest and during exercise, compared to untreated rats, the captopril treated animals showed significantly decreased LV weight/tibial length ratio(LV/TL)(p<0.01),increased LV cavity area and dimension(both p<0.01), decreased total myocardial area and noninfarcted area(both p<30.001) and reduced wall thicknesses in the noninfarcted and infarcted regions(both p<0.001). Compared to treated and untreated dsedentary rats, exercise significantly increased LV/TL(p<0.05) and epicardial and endocardial areas in the infarcted zone(both p<0.05) and decreased transmurality(p<0.01). Exercise decreased LV cavity area in the captopril treated groups(42.3+/-10.4 vs. 40.4+/-6.0mm2),whereas exercise increased LV cavity area in the untreated groups(33.5+/-8.9 vs. 39.1+/-6.2mm2)(p<0.05). CONCLUSION: These findings provide evidence in rats for evidence in rats for exaggerated left ventricular dilation and supperssion of compensatory myocardial hypertrophy globally and in the infarct zone with 3 weeks of captopril treatment following coronary artery reperfusion with acute nontransmural myocardial infarction. In addition, the effects of captopril on LV dilation and suppression of global and regional hypertrophic response were partially reversible by swimming exercise.

BACKGROUND: In order to evaluate the prevalence of enterovirus and cytomegalovirus infections to terminally failing hearts, the presence of enteroviral RNA and cytomegaloviral DNA was screened in the explanted hearts of transplantation recipients. METHODS: RNA and DNA extractions were performed from explanted failing hearts (N=22) and normal hearts (N=5). Reverse transcription-polymerase chain reaction (RT-PCR) of enterovirus and polymerase chain reaction (PCR) of cytomegalovirus were performed. In situ RT-PCR and in situ PCR were performed with positive nucleic acids of viruses. RESULTS: The positivity of enterovirus in failing hearts was 4.4% (1/22) and 0% (0/5) in normal hearts in nested RT-PCR. There was no significant difference in positivity of enteroviral RNA between failing and normal hearts. Nuclei of myocardium was stained in dark-violet color with in situ RT-PCR. The positivity of cytomegalovirus in failing hearts was 45% (10/22) and 40% (2/5) in nested PCR. There was no significant difference in positivity of cytomegaloviral DNA between failing and normal hearts. Nuclei of myocardium was stained in dark-violet color with in situ PCR. Positive chambers of cytomegalovirus were in decreasing tendency according to increasing patient's age. CONCLUSION: Enterovirus was very rarely observed in explanted terminally failing hearts and cytomegalovirus was frequently found both in explanted failing hearts and normal. These viruses have little direct causal relationship with the development of heart failure.

We investigated the 1,004 workers who worked in a automobile factory to study the epidemiologic characterist of dermatoses due to cutting oils. Among the workers, 667(66.4%) answered the questionnaire. They are belong to 5 departments of the factory-the Engine-Work(86), Power train Assembly(17). We measured the oil mist concentration in air of the departments and examined the workers who had dermatologic symptoms. The results were follows; 1) Oil mist concentration; Of all measured points(52), 9 points(17.2%) exceeded 5mg/m3-the time-weighed PEL- and one department had a upper confidence limit(95%) higher than 5mg/m3. 2) Dermatologists examined 213 workers. 172 of them complained any skin symptoms at that time-itching(32.5%), papule(21.6%), scale(15.7%), vesicle(12.5%) in order. The abnormal skin site found by dermatologist were palm(29.3%), finger & nail(24.6%), forearm(16.2%), back of hand(8.4%) in order. 3) As the result of physical examination, we found that 160 workers had skin diseases. Contact dermatitis was the most common; 69 workers had contact dermatitis alone(43.1%), 11 had contact dermatitis with acne(6.9%), 10 had contact dermatitis with folliculitis(6.3%), 1 had contact dermatitis with acne & folliculitis, and 1 had contact dermatitis with abnormal pigmentation. Others were folliculitis(9 workers, 5.6%), acne(8, 5.0%), folliculitis & acne(2, 1.2%), keratosis(1, 0.6%), abnormal pigmentation(1, 0.6%), and non-specific hand eczema(47, 29.3%). 4) The prevalence of any skin diseases was 34.0 per 100 in cutting oil users, and 13.3 per 100 in non-users. Especially, the prevalence of contact dermatitis was 23.0 per 100 in cutting oil users and 4.3 per 100 in non-users. 5) We tried patch test(standard series, oil series, organic solvents) on 49 patients to differentiate allergic contact dermatitis from irritant contact dermatitis and found 20 were positive. 6) In a multivariate analysis(independent=age, tenure, kinds of cutting oil), the risk of skin diseases was higher in the water-based cutting oil user and both oil user than non-user or neat oil user(odds ratio were 2.16 and 2.78, respectively). And the risk of contact dermatitis was much higher at the same groups(odds ratio were 5.16 and 6.82, respectively).

BACKGROUND: Leptin the ob gene product is secreted by adipocytes and binds to specific receptors in the central nervous system regulating energe intake and expenditure. Correlation between fat mass and leptin level is well established. However, data on the hormonal regulation of the leptin in human are scarce. Growth hormone (GH) has lypolytic action and patients with growth hormone deficiency (GHD) have showed higher leptin levels than expected for the obesity We investigated the changes in serum leptin levels and body mass index in children with GHD during GH therapy. METHODS: Thirty children with GHD participated. All subjects were 5~13 years old and in prepubertal stage. The causes of GHD were idiopathic in 15 and organic in 15 children. Patients received GH 0.6.7 IU/kg/week subcutaneously, in 67 divided doses and investigated at baseline and after 6 and 12 months of GH treatment. Serum leptin levels were determined with a human leptin and IGF-1 radioimmunoassay (Linco Research and Nichols Institute, USA). RESULTS: The height velocity was increased significantly after 12 months of GH treatment. Serum leptin concentrations were significantly reduced after 6 and 12 months of treatment but revealed no significant differences in the sex and the causes of GHD. Body mass indices were significantly reduced after treatment. Serum leptin levels positively correlated with body mass index at baseline and after 6 and 12 months of GH treatment. The serum IGF-1 level were increased significantly after GH treatment and did not significantly correlated with leptin levels at baseline and after treatment. CONCLUSION: This study demonstrated that serum leptin and body mass index were decreased with significant positive correlation during GH treatment in children with GHD.

The authors analysed 340 cases of the ocular injuries among 7633 out and in-patients who visited to the clinic of P.N.U. hospital during 5 years, from Jan. 1964 to Dec. 1968. Followings were discussed. 1. We found that 4.6% of all cases attending our eyes clinic was victims of ocular injuries. 2. The sex incidence showed that 78.9% of such ocular injuries occured in male and 21.1% in female. 3. The incidence was prevalent in young adult 21-30 years of age, and their large number of cases were injured from blowing and industrial accidents, while in children under 10 years of age sharp-pointed toys were more frequent causes. 4. The subconjunctival hemorrhage was the most frequent disturbance of ocular injuries and then came traumatic cataract and corneal foreign bodies in that order. 5. The prognosis of ocular injuries was generally poor, especially, poor, especially in the perforating and penetrating wound of the whether the foreign body was retained or not.
