Objectives : This study aim to find out the reason why perspiration related with the Heart in Korean Medicine. Results : Perspiration is closely connected with the Heart because sweat is a kind of ultrafiltrate of the blood and the Heart conducts blood. In order to perspire, it is necessary to increase blood flow to capillary surrounding sweat glands. The Heart plays an important role in increasing blood flow to capillary surrounding sweat glands. Perspiration controls the body temperature. It must be increase the blood flow to skin in order that down the high body temperature. The Heart plays an important role in increasing blood flow. Conclusions : Perspiration is closely connected with the Heart because sweat is a kind of ultrafiltrate of the blood and there are plenty capillary surround sweat gland. The Heart controls the blood flow to skin in order to regulate of body temperature.

610 cases of open heart surgery was performed in the Department of Thoracic and Cardiovascular Surgery, Pusan National University Hospital from July 1981 to September 1987. The clinical data was summarized as follows: 1. The age distribution of congenital heart surgery patients was 2 to 41 years old [mean; 13.2 years] and surgery for acquired heart disease was 10 to 57 years old [mean: 32.8 years]. 2. There were 389 cases [63.8%] of acyanotic congenital heart anomalies, 63 cases [10.3%] of cyanotic congenital anomalies and 158 cases [25.9%] of acquired heart disease. 3. For myocardial protection, Bretschneider and potassium glucose solution had been used as cardioplegic solution and then since 1983, GIK solution has been used with repeated infusion method once for every 20 to 30 minutes of time interval after starting initial cardioplegia during operation with excellent results. 4. The ingredient of the priming solution is Hartmann`s solution, sodium bicarbonate, mannitol, potassium chloride, fresh ACD whole blood, calcium chloride, heparin and dexamethasone. 5. There were 96 cases [15.7%] of mild hypothermia, 333 cases [54.6%] of moderate hypothermia and 181 cases [29.7%] of intermediate hypothermia. 6. The mortality rate was 2.3% [9 out of 389 cases] in acyanotic congenital heart disease, 36.5% [23 out of 63 cases] in cyanotic congenital heart disease and 10.8% [17 out of 158 cases] in acquired heart disease, with overall mortality rate of 8.0% [49 out of 610 cases].

Heart related diseases mainly caused by heavy work load and increasing stress in human daily life. Therefore, researches on mobile healthcare monitoring for daily life has been carried out. Notably, wearable healthcare monitoring system which has least restriction has been tried to provide an emergency alert of abnormal heart rate. In this study, we developed chair type unconstrained BCG measurement system which able to perform continuous heart status monitoring at the office and daily life in the unconstrained way. Furthermore, adaptive threshold is used to detect the heart rate from BCG signals. The HRV(heart rate variability) is calculated from heart rate interval. ECG signal measured using conventional method and BCG signal measured using unconstraint system are carried out simultaneously for the purpose of performance evaluation. From the comparison result, BCG signal shows a similar heart beat characteristic as ECG signal. This proves the possibility of practical implementation of unconstraint healthcare monitoring system. In addition, medical examination like valsalva maneuver is performed to observe the changes in HRV due to stress. By performing valsalva maneuver, heart is said to be placed under an artificial physical stress condition. Under this artificial physical stress condition, the time and frequency domain of HRV parameters are evaluated.

The purpose of this paper is to provide corpus-based quantitative analyses of HEART and HEAD in order to examine their actual usage status and to consider some cognitive linguistic aspects associated with their use. The two corpora COCA and COHA are used for analysis in this study. The analysis of COCA corpus reveals that the total frequency of HEAD is much higher than that of HEART, and that the figurative use of HEART (60%) is two times higher than its literal use (32%); by contrast, the figurative use of HEAD (41%) is a bit higher than its literal use (38%). Among all four genres, both lexemes occur most frequently in fictions and then in magazines. Over the past two centuries, the use of HEART has been steadily decreasing; by contrast, that the use of HEAD has been steadily increasing. It is assumed that the decreasing use of HEART has partially to do with the decrease in its figurative use and that the increasing use of HEAD is attributable to its diverse meanings, the increase of its lexical use, and the partial increase in its figurative use. The analysis of the collocation of verbs and adjectives preceding HEART and HEAD, as well the modifying and predicating forms of HEART and HEAD also provides some relevant information of the usage of the two lexemes. This paper showcases that the quantitative information helps understanding not only of the actual usage of the two lexemes but also of the cognitive forces working behind it.

An ischemic heart disease(IHD) is a anemic state of heart caused by disproportion between heart's demand and supply of oxygen. A patient who has this IHD feels serious chest pain called angina pectoris. In a keen condition it leads to a necrosis of heart muscles, known as myocardial infarction. In an ischemic heart disease the ECG waves gives us useful information of patients' heart. And CK(creatine kinase) in serum and Troponin T are the principal factors in diagnosis of IHD. In this study, the IHD patient classified by Sasang Constitutional Medicine had a notable medical effects. The symptoms of patient are disappeared and waves of ECG is closed to normal. The result of CK in serum is also recovered. So we report the healing process and results of this patient in this study.

The sterile alpha motif (SAM) is a putative protein interaction domain involved in a wide variety of biological processes. Here we report the identification and characterization of a novel gene, SAMD4B, which encodes a putative protein of 694 amino acids with a SAM domain. Northern blot and RT-PCR analysis showed that SAMD4B is widely expressed in human embryonic and adult tissues. Transcriptional activity assays show SAMD4B suppresses transcriptional activity of L8G5-luciferase. Over-expression of SAMD4B in mammalian cells inhibited the transcriptional activities of activator protein-1 (AP-1), p53 and p21, and the inhibitory effects can be relieved by siRNA. Deletion analysis indicates that the SAM domain is the main region for transcriptional suppression. The results suggest that SAMD4B is a widely expressed gene involved in AP-1-, p53- and p21-mediated transcriptional signaling activity.

Geft is a guanine nucleotide exchange factor, which can specifically activate Rho family of small GTPase by catalyzing the exchange of bound GDP for GTP. Geft is highly expressed in the excitable tissue as heart and skeletal muscle and plays important roles in many cellular processes, such as cell proliferation, migration, and cell fate decision. However, the in vivo role of Geft remains unknown. Here, we generated a Geft conditional knockout mouse by flanking exons 5-17 of Geft with loxP sites. Cre-mediated deletion of the Geft gene in heart using Mef2c-Cre transgenic mice resulted in a dramatic decrease of Geft expression. Geft knockout mice develop normally and exhibit no discernable phenotype, suggesting Geft is dispensable for the development of the second heart field in mouse. The Geft conditional knockout mouse will be a valuable genetic tool for uncovering the in vivo roles of Geft during development and in adult homeostasis.

A heart supplies bloods of about 15, 000 liters to each human organ in a day. A normal function of heart valves is necessary to this act of heart. The disease of heart valve develops to a narrowness of a closure, resulting in an abnormal circulation of bloods. In an attempt to eliminate the affliction of heart valves, the operation method to repair with artificial heart valves has been developed and saved numerous patients over past 30 years. This replacement operation has been performed since early 1960`s in Korea, but all the artificial heart valves used are imported from abroad with very high costs until recent years. The artificial heart valve using pyrolytic carbon has been developed at KAIST, which was proved to be stable in the mechanical performance and durability. Therefore, the in viva performance of this valve was examined through animal tests. The artificial heart valves used in this study are tilting disc type valves, in which the disc were made of graphite coated with pyrolytic carbon and the cages were made of titanium. In viva testings of these valves were performed in 12 dogs, in which right ventriculo-pulmonary arterial [Croup I] or inter-aortic [Croup IV] valved conduit was implanted using polytetrafluoroethylene conduits containing KAIST valve and aortic valve [Group II] or pulmonary valve [Croup III] was replaced by a KAIST valve with a 21mm or 19mm tissue annulus diameter. In group I and II, pre-and post-operative transvalvular pressure gradient was measured and compared with other prosthetic valves. During post operative period laboratory examination was performed including hemoglobin, hematocrit, red cell count, white cell, lactic acid dehydrogenase and platelet. The eight surviving dogs were sacrificed and autopsy was performed at 2, 6, and 8 weeks. KAIST valve has low transvalvular gradient and relatively high orifice area. Average ventriculo-aortic peak systolic transvalvular gradient was 14 mmHg in 21 mm valve and 19 mmHg in 19 mm valve. The valve has slight intravascular hemolysis effect. Thrombogenic effect of low polishing quality and eddy currents around small orifice is high. The valve has vulnerability of disc movement. These animal tests suggest that the improvement of the heart valve design, surface polishing state and prescription methods.

Interpostion arthroplasty with allograft has been known as a useful option for the shoulder arthropathy, but it has a limitation to immune response. We performed the pectoralis major muscle transfer for shoulder arthropathy. From January 2007 to December 2007, we performed the pectoralis major muscle transfer in 2 patients. They were 1 man and 1 woman, and the mean age of the patients was 70 years (range, 65 to 75). The average follow-up after surgery was 13 months (range, 12 to 14). We analyzed the clinical results by the American Shoulder and Elbow Surgeons (ASES) Score, and evaluated the pain by Visual Analogue Scale. The level of pain reduced from a preoperative average of 10 to a postoperative average of 1. The ASES scores increased from a preoperative mean of 9 to a postoperative mean of 58. These results indicated that interposition arthroplasty with the pectoralis major muscle transfer is a reliable treatment method for the shoulder arthropathy improving shoulder pain, and patient satisfaction.
