Coronavirus has been spreading rapidly around the world since it broke out in China in 2019. Respiratory diseases caused by coronavirus infection cause various diseases ranging from asymptomatic subclinical infections to severe pneumonia and cardiovascular complications, leading to death. In this regard, natural products are being studied to prevent various diseases caused by COVID-19. In current review, we would like to present mechanisms related to the inhibition of heart disease in ginseng and ginsenoside against SARS-CoV-2. In many previous studies, ginseng and ginsenoside are known to have antioxidant, blood flow improvement, improvement of vascular and heart function, blood pressure control, suppression of myocardial infarction and heart failure, and antiarrhythmia. Therefore, ginseng and ginsenoside have a possibility to suppress cardiovascular complications caused by COVID-19. Many of research provide evidence for ginseng and ginsenoside as treatments for the risk of cardiovascular complications. However, in this review, more specific contents on the proposition of the efficacy of ginseng and ginsenoside for COVID-19 should be presented. Therefore, we hope that researches to reduce cardiovascular complications of ginseng and ginsenoside for COVID-19 should be presented to reduce mortality for COVID-19.

The International Commission on Radiological Protection (ICRP) 103 recommends a cost-benefit analysis method as an auxiliary tool for scientific and rational decision-making for the principle of optimization of radiological protection. In order to conduct a cost-benefit analysis, the safety improvement of nuclear power by regulation must be measured and converted into monetary terms. The improvement of nuclear safety can be measured by reducing the radiation exposure dose of the people, and it is necessary to determine the coefficient to convert the radiation exposure dose into money. The monetary coefficient is calculated as the product of the statistical life value (VSL) and the nominal risk coefficient. In order to derive the monetary coefficient, the willingness to pay (WTP) can be estimated using the contingent valuation method (CVM), which quantifies the value of non-market goods by converting them into monetary units. WTP can be estimated based on the random utility model, which is the basic model for bivariate selection type conditional value measurement data. Statistical life value can be calculated using the estimated WTP and reduction in early mortality, and a monetary coefficient can be derived.

The heart block and bradyarrhythmia with or without Stokes-Adams attacks are serious, usually terminal events and the immediate mortality is very high. Stimulation with an artificial pacemaker is now an accepted form of treatment in cases of Stokes-Adams syndrome in which medication in unable to produce any lasting improvement. Permanent pacemaker therapy is indicated in these circumstances. The purpose of this report is to describe the successful use of pacemaker in 3 cases of Stokes-Adams syndromes and a case of sinoatrial block with bradyarrhythmia at the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University School of Medicine. Electrode catheter was passed through the right external jugular vein and attached to the endocardial surface of the right ventricle. In case 1, fixed type generator was used at first and for the case 2, 3, 4, and case 1 at second, demand type generators were used. The bipolar electrode catheters were used for the three cases and unipolar electrode catheter for case 4. The results of immediate and late period were satisfactory.

The effects of oligosaccharide supplementation on the growth performance, flock uniformity and GIT development of broiler chickens were investigated. Four diets, one negative control, one positive control supplemented with zinc-bacitracin, and two test diets supplemented with mannoligosaccharide (MOS) and fructooligosaccharide (FOS), were used for the experiment. Birds given MOS or FOS had improved body weight (BW) and feed efficiency (FCR), compared to those fed the negative control diet during the 35-d trial period. The effect on FCR became less apparent when the birds got older. FOS and MOS supplementation reduced the pancreas weight as a percentage of BW, with an effect similar to that of the antibiotic, at 35 d of age. Birds given MOS tended to have a heavier bursa (p = 0.164) and lower spleen/bursa weight ratio (p = 0.102) at 35 d of age. MOS and Zn-bacitracin showed a clear improvement on flock uniformity, compared to FOS. The mortality rate was not affected by FOS or MOS.

Total anomalous pulmonary venous return is a cardiac malformation in which there is no direct connection between any pulmonary vein and the left atrium but, rather all the pulmonary veins connect to the right atrium or one of its tributaries. TAPVC is a relatively uncommon anomaly, accounting for only about 1.5-3% of cases of congenital heart disease. Recently improvement in intraoperative techniques did eventually bring substantial improvements in the results in infants. 4 cases of TAPVC was successfully treated with one-stage operation, in the Dept. of Thoracic and Cardiovascular Surgery, National Medical Center in which 2 cases are supracardiac types and the other 2 cases are cardiac types. Sex ratio was 1:1, and the range of age was 2 years-18 years. The common pulmonary venous sinus was connected to the left vertical vein and innominate vein: in 2 supracardiac types and coronary sinus in 2 cardiac types. All cases are operated with standard cardiopulmonary bypass, and the hospital mortality was 0%.

Massive hemoptysis, usually rapid flooding of tracheobronchial tree and asphyxia, is associated with high mortality. We have controlled massive hemoptysis in two cases with use of bronchial artery angiography & selective bronchial artery embolization with Gelfoam particle. One case was inoperable case that was confirmed as TOF c severe pulmonary artery hypoplasia with massive hemoptysis due to hypertrophied bronchial artery and its collaterals. Another case was congenital ASD with pulmonary Aspergillosis, postop. empyema and BPF associated with massive bleeding due to erosion of hypervascular bronchial artery. We experienced dramatic improvement of general condition and cessation of massive hemoptysis for above two cases. No other problems and complication were noted during postop. hospitalization and follow-up period.

Myasthenia 8ravis is a disorder of neuromuscular function due to a reduction of available acetylcholine receptors at the neuromuscular junction. Typically, the muscle weakness is worse after effort and improved by rest. In 1939, Blalock and associated reported a case of patient with myasthenia gravis who was successfully treated by thymectomy. Since then, operation has become increasingly important in the management of this disease. From 1968 to 1983, 10 cases of myasthenia gravis were operated at the Department of Thoracic and Cardiovascular Surgery,College of Medicine, Seoul National University. 1.Among 10 cases, 4 were male and 6 were female. 2.Thymectomy was performed in 9 cases, and 1 case of malignant thymoma with deeply infiltration to adjacent structure was not resectable. 3.There was 1 operative mortality with respiratory failure. 4.During follow-up period, most of them showed symptomatic improvement, but complete remission was not noticed in any case.

During the preantibiotic era, lung abscess carried a high mortality, however, with the introduction of penicillin and subsequently other antibiotics, significant improvement was resulted. Clinical review was performed on 27 cases of lung abscess, those were admitted and treated at the Department. of Thoracic and Cardiovascular Surgery, Chonbuk University Hospital, from 1979 to August, 1986. The following results were obtained. The most common age of occurrence was between the age of 40 and 60 [14 cases] and 22 cases were male patients. The common symptoms were cough, putrid sputum production, fever and chilliness. Numerous etiological factors may play a role in the formation of lung abscess; pneumonia [7 cases], aspiration [5 cases], bronchiectasis [2 cases], liver abscess [1 case] and broncholith [1 case]. The bacteriologic study revealed increased incidence of Enterobacteriaceae [15 cases]. The treatment methods were postural drainage [12 cases]. pneumonostomy [5 cases], lobectomy [8 cases], thoracostomy [2 cases].

Increased clinical interest, stimulated by newer diagnostic techniques, has made it apparent that Ebstein`s anomaly represents a spectrum of right heart abnormalities. In the usual case, the septal and posterior leaflets of the tricuspid valve are not attached to the true annulus, but are displaced distally into the ventricle. Also the degree of malattachment and the structural deformities of the cusps may vary greatly. Recently we experienced 6 cases of Ebstein`s anomaly who underwent corrective operation in our hospital. Five patients were operated by plication and annuloplasty techniques based on the construction of a monocusp valve by the use of the anterior leaflet. Remained one was operated on by tricuspid valve replacement using No 31 mm C-E tissue valve. There was no operative mortality and the postoperative courses were relatively good with marked symptom improvement.

Sixty-one bronchiectatic patients were reviewed who were treated by surgical intervention in the Department of Thoracic and Cardiovascular Surgery, Chonnam University Hospital during the recent 14 years from January of 1965 to August of 1978. 1. Various pulmonary resection was performed; lobectomy was 55.5%, lobectomy and segmental resection 20.6%, bilobectomy 13.1%, lobectomy, segmental resection and thoracoplasty 4.9% and pneumonectomy was 3. 2%. 2. The most common associated disease was pulmonary Tbc, its frequency was 47.5% and next was chronic bronchitis [31%]. 3. The postoperative complication was observed in 19.6% [12 cases] and the most common was wound infection. 4. The possibility of recurrence was relatively high in the cases of residual lesion and it needs more intensive medical care. 5. The surgical result was satisfactory in 86.9% (53 cases), slight improvement in 4.9% (3 cases) and the mortality rate was 1.6% (1 case).
