Necrotizing fasciitis (NF) is defined as rapidly progressive necrosis of subcutaneous fat and fascia. Although NF of the face is rare, its mortality rate is nearly 30%. It usually originates from dental infection and can lead to involvement of the neck, mediastinum, and chest wall. Complications resulting from pre-existing systemic diseases can increase the mortality rate. Known complication factors for NF include diabetes, malnutrition, advanced age, peripheral vascular disease, renal failure, and obesity. Here, we report a case of NF originating from dental infection in an 88-year-old woman already diagnosed with hypertension, thoracic aortic aneurysm, and renal diseases. Such conditions limited adequate surgical and antibiotic treatment. However, interdisciplinary treatment involving multiple departments was implemented with good results.

In order to evaluate the myocardial injury in cardiac valvular and coronary surgery, variables of creatine kinase[CK], myocardial band of CK[CK-MB], lactate dehydrogenase[LDH], aspartate aminotrasferase[AST] were measured in the preoperative[Preop], the operation day[POD0], and the first[POD1], third[POD3], fifth[POD5], seventh[POD7], ninth[POD9] day after operation in 29 patients. The subjects were divided into two groups according to the diseases: group V [valvular disease, n=16] and group C[coronary artery disease, n=13]. Each group was subdivided into two subgroups according to the duration of aortic crossclamping time[ACT]; group VI[ACT 120min, n=7] and group VII[ACT>120min, n=9]; group CI[ACT 120min, n=6] and group CII[ACT>120min, n=7]. The results were as followed 1. The values of CK between group V and group C had no significant difference. The values of CK in group CII were significantly greater than those in group CI and the values of CK in group VII were significantly greater than those in group VI. 2. Percentages of CK-MB between groups had no significant difference. 3. The serum levels of LDH in group V were significantly greater than those in group C. The serum levels of LDH in group VII were significantly greater than those in group VI. 4. The serum levels of AST in group VII were significantly greater than that in group VI. We were concluded that myocardial injury was more related with the duration of aortic cross clamping time rather than the type of diseases.

Houttuynia cordata Thunb.[H.cordata]belonging to Saururaceae, is a wild medicinal herb of perennial plants, and grows well in a place with a lot of shade and moisture. The medical action of H.cordata is reported to have an antitumer effect, toxicity-suppressive effect, antifungal effect, diuretic effect, and antioxidative action, but its effect hasn't been reported on cardiovascular diseases, such as ateriosclerosis and hypertension yet. This study intended to confirm the effect of the water extract of H.cordata on the migration and proliferation of rat aortic smooth muscle cells. Such results show that the water extract of H.cordata suppresses the migration and proliferation of rat aortic smooth muscle cells. It is believed that a useful clue will be offered later to the prevention of cardiovascular diseases such as ateriosclerosis and hypertension, and the development of their medicines on the basis of the fact.

Aortobronchial fistula may cause a massive fatal hemoptysis. Recently prosthetic aortic graft insertion or endovascular stent graft is a cause of aortobronchial fistula. We report a rare case of hemoptysis from a fistula between an aortic arch aneurysm and the left main bronchus in a patient who had undergone an endovascular stent graft in pseudoaneurysm of descending thoracic aorta one year before.

The efficacy of cold blood potassium cardioplegia during periods of ischemic arrest was assessed in 88 patients undergoing open heart surgical procedures at Chonnam National University Medical School from December, 1987 to January, 1989. The purpose of this study was to determine if the aortic cross clamping time[ACCT] over 120 minutes correlated with operative mortality, incidence of postoperative ventricular tachyarrhythmias, needs of postoperative inotropic support and serum enzyme levels. The patients were divided according to aortic cross clamping time[less than 120 minutes and 120 minutes or greater]. The results were as follows: 1. The operative mortality was 3.2% in ACCT<120min group and 7.7% in ACCT>120 min group. 2. The incidence of postoperative ventricular tachyarrhythmia was 1.6% in ACCT <120min group and 11.5% in ACCT>120min group[p<0.05]. 3. The incidence of postoperative inotropic support in congenital heart disease was 13.0Fo in ACCT<120min group and 45.0%o in ACCT>120min group[p<0.05]. The incidence in acquired heart disease was 26.0% in ACCT<120min group and 40.0% in ACCT> 120min group. 4. After cardiopulmonary bypass, serum GOT, LDH, CPK and CPK - MB were elevated prominently. Children showed higher value of the enzymes examined than adults did before and after cardiopulmonary bypass. In congenital heart diseases, postoperative serum GOT, LDH, CPK and CPK - MB levels of ACCT>120min group were significantly higher than those of ACCT<120min group. Postoperative serum GOT, LDH and CPK - MB levels of ACCT>=120min group were significantly higher than those of ACCT<120min group also in acquired heart diseases. The results suggest that the myocardial protective effect with cold blood potassium cardioplegic solutions was not sufficient when the aortic cross clamping time was over 120 minutes.

Cardioplegia and myocardial protection were performed under cardiopulmonary bypass during open-heart surgery with the use of cold St. Thomas Hospital cardioplegic solution [4=C] for the coronary artery perfusion and normal saline solution [4- C] for the topical cardiac cooling. To maintain the state of myocardial protection, coronary artery reperfusion was carried out using St. Thomas Hospital cardioplegic solution at the interval of 30 minutes. A total number of patients studied were 57 cases, including 37 cases of correction for congenital cardiac anomalies and 20 cases for acquired heart valvular diseases. Cardiopulmonary bypass time during the surgery was observed to be average of 87.89*47.55 hours, aortic cross-clamping time to be average of 76.68~44.27 hours raging from 30 to 191 minutes. In order to evaluate the effects of myocardial protection in the surgery, serum enzyme levels were determined. To observe the relationship between aortic cross-clamping time and myocardial protection effects, patients studied were divided into the following 3 groups. I group: aortic cross-clamping time, 60 minutes, II group: aortic cross-clamping time, 90 minutes, III group: aortic cross-clamping time, over 91 minutes. 1. Changes in serum enzyme levels in postoperative period. [1] SCOT; The postoperative value [increased over 200 units] for ischemic myocardial injury during operation was observed in 11 cases [19.3% of the total] of the total patients studied, of which 4 cases [13.3%] in I group, 1 case [10.0%] in II group, and 6 cases [35.3%] in III group. [2] LDH; The positive value [increased over 900 units] for ischemic myocardial injury during operation was observed in 9 cases [15.7% of the total] of the total patients studied, of which 2 cases [6.6%] in I group, 1 case [10.0%] in II group, and 6 cases [35.3%] in III group. [3] CPK; The positive value [increased over 800 units] for ischemic myocardial injury during operation was observed in 10 cases [17. 5% of the total] of the total patients studied, including 4 cases [13. 3%] in I group, 1 case [10.0%] in II group, and 5 cases [29.4%] in III group. 2. The myocardial protection method used in the present study was demonstrated to be effective for the myocardial protection in the surgery with aortic cross-clamping time of up to 90 minutes. A few ischemic myocardial injury were observed in the surgery with aortic cross-clamping time over 91 minutes, but no significant cardiac dysfunction was noted. The surgery with aortic cross-clamping time of up to 191 minutes did not appear to give rise any significant interference with postoperative recovery.

Coarctation of the aorta is frequently associated with intracardiac disease. It is very difficult to decide on the best method for surgically treating adult patients with these combined heart diseases. We performed single-stage repair via a modified Bentall operation and by creating an intrapericardial ascending-descending aortic bypass through a median sternotomy in a patient with coarctation of the aorta and annuloaortic ectasia, and the latter was associated with aortic valve regurgitation.

Atherosclerosis, which manifests as acute coronary syndrome, stroke, and peripheral arterial diseases, is a chronic inflammatory disease of the arterial wall. Prunella vulgaris, a perennial herb with a worldwide distribution, has been used as a traditional medicine in inflammatory disease. Here, we investigated the effects of P. vulgaris ethanol extract on TNF-${\alpha}$-induced inflammatory responses in human aortic smooth muscle cells (HASMCs). We found that P. vulgaris ethanol extract inhibited adhesion of monocyte/macrophage-like THP-1 cells to activated HASMCs. It also decreased expression of intercellular adhesion molecule-1, vascular cell adhesion molecule-1, E-selectin and ROS, No production in TNF-${\alpha}$-induced HASMCs and reduced NF-${\kappa}B$ activation. Furthermore, P. vulgaris extract suppressed TNF-${\alpha}$-induced phosphorylation of p38 mitogen-activated protein kinase (MAPK) and extracellular signal-regulated kinase (ERK). These results demonstrate that P. vulgaris possesses anti-inflammatory properties and can regulate TNF-${\alpha}$-induced expression of adhesion molecules by inhibiting the p38 MAPK/ERK signaling pathway.
