  • Objectives : The purpose of this study is to compare the effects of laser acupuncture to the 532 nm on the five transport points with the heart meridian for treatment to hypertensive disease in rats with L-NAME induced hypertensive. Methods : Hypertensive was induced by L-NAME for 3 weeks. The laser acupuncture therapy on the five transport points of heart meridian(Laser Well Point-HT9, Laser Brook Point-HT8. Laser Stream Point-HT7, Laser River Point-HT4 and Laser Sea Point-HT3) was treated twice a week for 5 times. The hypertensive was measured using a cardiac hypertrophy, atherogenic index, TG/HDL-cholesterol ratio, TCHO, HDLC, TG, AST, ALT, antioxidative effectiveness and glutathione peroxidase quality of hypertensive rats induced by L-NAME. Results : Blood pressure were decreased significantly after the laser acupuncture of Well, Brook and Sea Point groups. Cardiac hypertrophy were decreased at the laser acupuncture of Brook and Stream Point groups. Athrogenic index was decreased at the laser acupuncture of Well, Stream, River and Sea Point groups. TG/HDL-cholesterol ratio was decreased at the laser acupuncture of all groups. Total cholesterol was decreased significantly at the laser acupuncture of Well Point group. High density lipoprotein cholesterol and total cholesterol were decreased significantly at the laser acupuncture of Well, Stream and River Point groups. Triglyceride was decreased significantly at the laser acupuncture of Stream Point group. Cu/Zn-Superoxide Dismutase (Cu/Zn-SOD) and glutathione peroxidase(GPX) were increased significantly at the laser acupuncture of Well Point group. Conclusions : The laser acupuncture treatment in five transport points of the Heart Meridian was effective for lowering blood pressure, cardiac hypertrophy, Atherogenic index and HTR, and for enhancing antioxidant activity.

  • Objective: To assess left ventricular remodeling patterns using cardiac computed tomography (CT) in children with congenital heart disease and correlate these patterns with their clinical course. Materials and Methods: Left ventricular volume and myocardial mass were quantified in 17 children with congenital heart disease who underwent initial and follow-up end-systolic cardiac CT studies with a mean follow-up duration of 8.4 ± 9.7 months. Based on changes in the indexed left ventricular myocardial mass (LVMi) and left ventricular mass-volume ratio (LVMVR), left ventricular remodeling between the two serial cardiac CT examinations was categorized into one of four patterns: pattern 1, increased LVMi and increased LVMVR; pattern 2, decreased LVMi and decreased LVMVR; pattern 3, increased LVMi and decreased LVMVR; and pattern 4, decreased LVMi and increased LVMVR. Left ventricular remodeling patterns were correlated with unfavorable clinical courses. Results: Baseline LVMi and LVMVR were 65.1 ± 37.9 g/m2 and 4.0 ± 3.2 g/mL, respectively. LVMi increased in 10 patients and decreased in seven patients. LVMVR increased in seven patients and decreased in 10 patients. Pattern 1 was observed in seven patients, pattern 2 in seven, and pattern 3 in three patients. Unfavorable events were observed in 29% (2/7) of patients with pattern 1 and 67% (2/3) of patients with pattern 3, but no such events occurred in pattern 2 during the follow-up period (4.4 ± 2.7 years). Conclusion: Left ventricular remodeling patterns can be characterized using cardiac CT in children with congenital heart disease and may be used to predict their clinical course.

  • 파브리병(Fabry disease)은 매우 드문 X-연관 유전 대사 질환으로 알파 갈락토시다아제(alpha galactosidase A)의 결핍으로 인하여 다양한 세포 및 기관에 글리코스핑고지질(glycosphingolipid)의 축적을 초래하는 질환이다. 심장 침범이 비교적 흔하며 비정상적인 지질침착으로 인한 심근 염증, 좌심실 비대 및 심근 섬유증을 일으킨다. 심장 침범은 환자 예후를 결정하는 중요한 요인이므로 이를 진단하는 것은 매우 중요하다. 심장 자기공명영상은 심실의 기능, 부피 측정을 위한 표준기법으로 알려져 있으며 심근의 조직 변화를 볼 수 있는 유용한 기법이다. 특히 최근 많이 쓰이는 T1 지도화 기법을 통한 심근 조영 전 T1 수치를 이용하여 파브리병의 심장 침범을 조기 진단할 수 있으며 자기공명영상을 이용한 심근 질량 측정으로 치료 모니터링을 할 수 있다. 심장 자기공명영상은 파브리병 환자에서 다양한 역할을 할 수 있을 것으로 생각되며 이에 대해 정리해보고자 한다.

  • A Total of Forty eight patients underwent open-heart surgery for correction of tetralogy of Fallot at the Seoul National University Hospital from January 1974 to October 1976, with an overall survival rate of 77 per cent. Operative mortality varied according to severity of the lesion, age of the patient, nature of previous surgical treatment and presence or absence of an outflow tract patch across the pulmonary valve ring. Eleven patients died in the early postoperative period and thirty seven patients were discharged from the hospital alive. A patch of the right ventricular outflow tract and pulmonary annulus was required to relieve pulmonic stenosis in 24 patients. There were 10 deaths in this group (42%) as compared to 1 death in the group of 24 patients who were corrected without a patch. Operative mortality was especially higher when an inlay patch was placed across the pulmonary valve ring. This may be related to the possibly greater anatomic severity of these cases and to the longer operating time when a patch was used. The electrocardiogram showed right ventricular hypertrophy in 35 cyanotic patients. Intraventricular conduction was normal in 34 patients before operation. It was normal postoperatively in only 5 of 34 patients in this group who survived surgery. Complete right bundle branch block appeared at operation in 21 patients, and 8 patients developed incomplete right bundle branch block. Major causes of death were progressive cardiac failure (4), Complete atrioventricular dissociation (3), bleeding (2), cardiac tamponade (1), and sudden cardiac arrest (1)

  • Magnetocardiography (MCG) is the measurement and analysis of the magnetic component of the electro-magnetic field of the human heart, usually conducted externally, using extremely sensitive devices such as a Superconducting Quantum Interference Device (SQUID). MCG is a totally noninvasive method, it uses neither radiation nor ultrasonics. The magnetic activity of the heart is registered from outside the thorax. MCG has a very high sensitivity and a high spatial resolution for very a small, local myocardial current. In comparison to the electrical signals measured by an ECG, the magnetic signal does not disturb the boundaries of tissues with different electrical properties. MCG measures the myocardial function rather than describing the morphology. MCG is a relatively new technique that promises good spatial resolution and extremely high temporal resolution, thus complementing other heart activity measurement techniques such as Electrocardiography (ECG). The clinical uses of MCG are in detecting various cardiac disorders including myocardial infarction, ventricular hypertrophy, ventricular conduction defects, Wolff-Parkinson-White (WPW) syndrome, sudden cardiac death and fetal magnetocardiography. Magnetocardiography may be used alone or together with electrcardiography for the measurement of spontaneous or overloaded activity and for research or clinical purposes.

  • Surrogate tissue analysis incorporating -omics technologies has emerged as a potential alternative method for evaluating toxic effect of the tissues which are not accessible for sampling. Among the recent applications, blood including whole blood, peripheral blood lymphocytes and peripheral blood mononuclear cells (PBMCs) was suggested as a suitable surrogate tissue in determining toxicant exposure and effect at the pre- or early clinical stage. In this application, we investigated transcriptomic profiles in astemizole treated Cynomolgus monkey's PBMCs. PBMCs were isolated from 4-6 years old male monkeys at 24 hr after administration45 Helvetica Light (10 mg/kg, 30 mg/kg). Gene expression profiles of astemizole treated monkey's PBMCs were determined using Affymetrix $GeneChip^{(R)}$ Human Genome U133 plus 2.0 arrays. The expression levels of 724 probe sets were significantly altered in PBMCs at 10 or 30 mg/kg after astemizole administration following determination of paired t-test using statistical criteria of ${\geq}$$1.5-fold changes at P<0.05. Gene expression patterns in PBMCs showed a considerable difference between astemizole 10 and 30 mg/kg administration groups in spite of an administration of the same chemical. However, close examination using Ingenuity Pathway Analysis (IPA) software revealed that several gene sets related to cardiotoxicity were deregulated at astemizole 10 and 30 mg/kg administration groups. The deregulation of cardiac hypertrophy related genes such as TXN, GNAQ, and MAP3K5 was observed at 10 mg/kg group. In astemizole 30 mg/kg group, genes involved in cardiotoxicity including cardiac necrosis/cell death, dilation, fibrosis, and hypertrophy were also identified. These results suggest that toxicogenomic approach using PBMCs as surrogate tissues will contribute to assess toxicant exposures and identify biomarkers at the pre-clinical stage.

  • Background: Hydrogen sulfide is a toxic substance that humans can be exposed to occupationally, and cases of hydrogen sulfide poisoning of workers in industrial sites are commonly reported. However, there have been no cases of poisoning of the public due to an unauthorized discharge of wastewater, so it is important to describe this incident. Case presentation: In a small village in Jeollanam-do, Republic of Korea, accounts of a terrible stench had been reported. A 26-year-old man who lived and worked in a foul-smelling area was taken to the emergency room with a headache, dizziness, nausea, and repeated syncope. A subsequent police and Ministry of Environment investigation determined that the cause of the stench was the unauthorized discharge of 9 tons of wastewater containing hydrogen sulfide through a stormwater pipe while the villagers were sleeping. The patient had no previous medical history or experience of symptoms. Leukocytes and cardiac markers were elevated, an electrocardiogram indicated biatrial enlargement, left ventricular hypertrophy, and corrected QT interval prolongation. Myocardial hypertrophy was detected on a chest computed tomography scan, and hypertrophic cardiomyopathy was confirmed on echocardiography. After hospitalization, cardiac marker concentrations declined, symptoms improved, and the patient was discharged after 7 days of hospitalization. There was no recurrence of symptoms after discharge. Conclusions: We suspect that previously unrecognized heart disease manifested or was aggravated in this patient due to exposure to hydrogen sulfide. Attention should be paid to the possibility of unauthorized discharge of hydrogen sulfide, etc., in occasional local incidents and damage to public health. In the event of such an accident, it is necessary to have government guidelines in place to investigate health impact and follow-up clinical management of exposed residents.
