Objectives : These days many people tend to prefer spicy taste. The purpose of this study was to find out the relationship between prefer spicy and physical symptoms. Methods : We examined the subjective physical condition of patients who visited L/C clinic during the period between January and June 2023 by conducting a survey. The survey was completed voluntarily, and the anonymity and confidentiality of the research data were strictly protected, and it was stated that patients could withdraw at any time if they did not want to participate. Patients who refused to complete the survey and patients with limited capacity to give consent were excluded. The survey took about 10 minutes to complete. We analyzed 248 cases who answered the survey and found that 66 patients had a high spicy preference. Results : As a result, participants with high spicy taste preference tended to have general body symptoms such as fever, sweat, and thirst; digestive symptoms such as belching, constipation, bloody stools, and abdominal distension; genitourinary symptoms such as yellowish urine, urinary retention, white fluor albus, and premenstrual tension; and neuromuscular symptoms such as edema, blepharospasm, and cold hands. Conclusion : People who have general body symptoms, digestive symptoms, genitourinary symptoms and neuromuscular symptoms described above should try to eat as little spicy food as possible and make sure they get a good balance of the five flavors.

In many applications of operational amplifiers to high quality and precision electronic circuit, such as active RC filters, the frequency response characteristics of the opamp becomes the primary limiting factor in circuit performance. In this paper, means of compensating for the finite gain bandwidth of operational amplifier. when used in voltage-controlled voltage source structures, are described. A universal active compensation scheme is proposed which can be used with operational amplifier voltage controlled voltage source, When looked upon as a general three-port building block. It is shown that phase shift contributed by imperfect operational amplifiers are virtually eliminated over an extended frequency range. Experimental result are given

Twelve patients underwent surgical interventions for aortic aneurysms consecutively from September 1986 to September 1990 in the Department of Thoracic and Cardiovascular Surgery, Yeungnam University Hospital. They were all men ranging in age from 25 to 68 years with the mean age of 48 years. Five patients of them had aneurysms involving ascending aorta, one aneurysm involving both ascending and descending aorta, four aneurysms involving descending thoracic aorta, and the others had aneurysms involving abdominal aorta. According to morphological classification, six cases of them were in dissection and the others in fusiform aneurysms. All the cases were pathologically true aneurysms and four of them were in acute status. According to causal classification, seven patients of them had atherosclerosis, three cystic medial necrosis, and the others had syphilis and trauma respectively. Six patients with ascending aortic aneurysm had annuloaortic ectasia with aortic regurgitation and underwent ascending aortic graft and aortic valve replacement[Bentall`s operation]. The others with descending thoracic and abdominal aortic aneurysms underwent Dacron graft replacement. Both hemorrhage necessitating reopening of the chest and wound dehiscence were observed in three patients and hoarseness in one patient. Cerebrovascular accident occurred three and a quarter years postoperatively in one patient and he died two days later. The others were followed up via OPD and have been doing well postoperatively.

We have performed a prospective study to assess the efficacy of suction drainage in 45 patients with primary spontaneous pneumothorax and 15 patients with secondary spontaneous pneumothorax, treated by closed chest tube drainage with underwater seal during the period Jan. 1990 to Dec. 1990 at the Department of Thoracic and Cardiovascular Surgery, Yeungnam University Hospital. The patients were divided randomly into two groups, 28 cases receiving suction and the other 32 cases no suction. The success rate was 82.1% for the former and 87.5% for the latter with the overall success rate of 85.0% and there was no significant difference in success rate between the two groups According to the causes and the extent of pneumothorax, the difference between the success rates of the two groups was also not significant statistically. But according to the duration of air leakage, suction group under 2 days showed a high success rate[46.4%] and the same group with 3-4 days, a relatively low success rate[21.4%] compared with that of the former. We conclude that the suction treatment is somewhat valuable in shortening the tubing time in patients with small amounts of air leakage, but it doesn`t seem to increase the success rate in all patients.

The myocardial temperature was monitored in 19 patients of open heart surgery using the Shiley myocardial temperature probe in Department of Thoracic and Cardiovascular Surgery, Yeungnam University Hospital. The myocardial temperature were measured time-wise: initial and 15 minutes following the infusion of the cardioplegic solution into the aortic root and upon reinfusion, which is 30 minutes apart from the initial. The measurements were made in the anterior wall of the right ventricle, the posterior wall of the left ventricle and the interventricular septum. Immediately after initial infusion, the temperature of the right ventricle[10.7 $\pm$4.3oC] was the lowest and that of the left ventricle[12.9$\pm$3.9 oC] the highest in the mean values among all 19 patients. However, no significant differences were noted among the different regions. At 15 minutes after infusion, the lowest temperature was in the right ventricle[17.5$\pm$5.1 oC], followed by interventricular septum[17.9$\pm$2.9 oC], and left ventricle[21.4$\pm$2.5 oC]. At 30 minutes after infusion, the lowest temperature was measured in the interventricular septum[13.6$\pm$2.7 oC ], followed by right ventricle[13.8$\pm$4.0 oC] and left ventricle[14.5$\pm$4.5 oC ]. Evaluating changes of myocardial temperature according to postinfusion time, the temperature at 15 minutes after infusion showed significant increase as compared with that immediately after the infusion in all three regions[p<0.05] and the temperature at 30 minutes after infusion showed significant decrease as compared with that at 15 minutes after the infusion in the left ventricle and the interventricular septum[p<0.05]. The left ventricle was rewarmed most rapidly and its temperature the highest in the mean values, Accordingly, the maintenance of optimal hypothermia of the left ventricle indicated a very careful factor in myocardial protection.

A 39 year-old woman presenting with a hemoptysis, pulmonary infiltrate was found to have thoracic actinomycosis by the specimens of excised lung. Recently, pulmonary actinomycosis is very rare by the widespread use of antibiotics. Clinical, radiological, and microbiological findings can be nonspecific. The diagnosis is dependent on a high index of suspicion. Chances for cure are excellent with lengthy antibiotic administration. The purpose of this paper is to review our experience and to remind us of pulmonary actinomycosis.
