In the beginning of anesthetic training, one of the clinical practices that anesthetists have to learn is manually controlled ventilator techniques. The popularity of manually controlled ventilatory techniques has been gradually decreased with increased use for anesthetic ventilators. However it is important and basic for the anesthetists to master manually controlled ventilator techniques skillfully. Recently, we analyzed the arterial blood gas in 30 cases before and during general anesthesia, and studied the effects of the manually controlled ventilation on the pulmonary gas exchange. The results were as follow; 1) Mean value of PaCO₂ during the manually controlled ventilation, 29.9±2.0 mmHg was decreased statistically comparing with that of PaCO₂ before the anesthesia, 39.8±2.8 mmHg. 2) Mean values of pH and HCO₃⁻ during the manually controlled ventilation were 7.48±0.03, 22.2±2.4 mEq/1, respectively and values before the anesthesia were 7.41±0.02, 25.2±1.8 mEq/1, respectively. 3) Mean value of PaO₂ and O₂ saturation during the manually controlled ventilation were 270.0±28.8 mmHg, 99.6±0.2%, respectively and values before the anesthesia were 92.5±4.0 mmHg, 96.9±1.0%, respectively. These results indicates that manually controlled ventilation at our department of anesthesiology produced mild hyperventilatory state. However these were no significant changes in cerebral blood flow and other biochemical parameters.

PURPOSE: The purpose of this study was to a quire the supplemental information needed by the general public. MATERIALS AND METHOD: Subjects of the study, totalling 1576, were from the three major cities of Taegu, Kwang-joo, Pusan and their surrounding districts. The subjects recruited were between the ages of study were developed by these researchers based on literature review and professional experience. The data were analysed by computing frequencies, percentages and testing ANCOVA in SAS program. RESULTS: It was noted that the knowledge level of cancer prevention and early detection for the most common cancers in Korea(stomach, lung, liver, cervical, and breast cancer) was low. Knowledge that the subjects had was correct or extremely limited. Subjects had a positive attitude about engaging in cancer prevention and early detection. They were motivated to earn more about it once they recognized cancer as being a fatal disease. Another finding is that is would be necessary to encourage an improvement in subject health habits. the percentage of subjects who had screening tests for cancer was very low. Regular screening test's rate for the five major cancers were very rare. The majority of subjects had not undergone any diagnostic tests. CONCLUSION: the results of this survey could be used as a framework for the developmental strategies of an educational program for the general population. The response of subjects was favorable, as they were willing to take preventative action independently.

Atherosclerotic heart disease is a major source of cardiovascular morbidity and mortality in adult populations. To assess the prevalence of anatomical and functional abnormalities of the heart in such patients, we studied total 50 subjects with atherosclerotic heart disease by echocardiography and compared with 27 control subjects. We found significant change(p<0.05) of aortic root dimension, left ventricular mass, mitral valve E-F slope, E-point septal separation, and functional measurements show significant change in ejection fraction and fractional shortening of left ventricle. Characteristically, abnormal septal movement reveals in 70% of patients including paradoxical, flat & diminished, hyperactive motion, and among them paradoxical movement is the most frequent. Also left ventricular posterior wall movement is abnormal in 30% of the patient group. The prevalence of echocardiographic abnormalities is 80 percentile of total, which include 30 percentile subjects with only echocardiographic abnormalities without abnormality in 12-lead ECG, chest X-ray and laboratory findings. And these abnormalities can be detected well by echocardiography before they were otherwise apparent.

Proliferating trichilemmal tumor is one of rare benign tumors of the skin appendages, considering as hamartoma of the terminal hair follicle, isthmic segment of the outer root sheath. We report a case of numerous proliferating trichilemmal tumors admixed with ordinary trichilemmal cysts with femilial history in 64-year-old man. He has total 157 lesions, which are chiefly located in scalp (48), back (32), and also face, neck, trunk, extremities. Histologically, the tumor is composed of irregularly arranged and ansatomosed trabeculae, lobules, or sheets of proliferated trichilemmal squamous epithelium with peripheral palisading of the basaloid cells. Several layers of squamoid or ovoid cells have PAS-positive clear cytoplasm. And it also shows abrupt amorphous, trichilemmal keratinization. Some squamous eddies with mild cellular atypism are associated, but definite invasion or other evidence of the malignancy is not found. usual multiple trichilemmal cysts are admixed with tumor and occasionally exhibit connection between them.

In the intestinal perforation during hydrostatic reduction for intussusception, the diluted isotonic Gastrografin may prevent body fluid shifting to peritoneal space, and granulomatous reaction resulting in intestinal obstruction, which can be induced by Barium on the peritoneal surface. We have experienced two perforations from 563 Gastrografin reductions during the last five years. One of the perforated cases had no complication on one year follow up after ileocecectomy, but the other, who was in the state of shock before the reduction, died at 133rd day after the operation. The cause of death was aspiration during the feeding. We report the above two cases of intestinal perforation by Gastrografin reduction without evidence of fatal complication.

Dieulafoy's vascular malformation is a rare cause of massive gastrointestinal bleeding. Most often it occurs in stomach within 6 cm from the gastroesophageal junction. Only a few cases have been reported to occur in the small intestine and colon. Occasionally, Dieulafoy's lesion of small intestine is difficult to recognize because of rarity, a paucity of symptoms and negative findings on barium studies. Therefore, this lesion needs to be considered in a patient with massive lower gastrointestinal bleeding. We report a case of Dieulafoy's vascular malformation in ileum 2 m proximal to ileocecal value in a 41-year-old woman who visited emergency clinic because of hematemesis, dizziness and vomiting. Small intestine revealed a wide-caliber artery within the submucosa showing intimal thickening, medial muscular hypertrophy and thrombosis.

A study was undertatken to determine whether the pressure preset ventilator such as the Bennett PR-1 or PR-2 that are used for respiratory care in the intensive care unit or in the recovery room after anesthesia could also be used as and anesthetic ventilator for pediatric anesthesia. Maintaining anesthesia with halothane(0.5~1.0%)-N2O(2.51/min)-O2(2.51/min)-pancuronium bromide(0.1mg/kg) and using the Jackson-Rees modified Ayre's T-piece, the reservoir bag was removed from that device and the reservoir tube was connected to the pressure present ventilator. The inspiratpry pressure of the ventilator was fixed at 15cm H2O and the respiratory frequency was controlled at 30/min in 15 patients under 10kg of body weight, and at 25/min in 15 patients weighing 11~17kg. Arterial blood gas tension was measured 30 minutes after ventilator use. The following results were obtained: 1) pH: 7.28~7.44(7.35+/-0.04) 2) PaCO2: 28.4~41.3mmHg(35.4+/-2.9mmHg). 3) PaO2: 184.9+/-289.0mmHg(242.7+/-30.5mmHg). 4) HCO2(-): 15.5~23.5mEq/L(19.8+/-1.9mEq/L). 5) B.E.: -10.0~-0.6mEq/L(-4.6+/-2.3mEq/L) The above values of arterial blood gas tension showed a normal ranges in all cases. Therefore, it could be assumed that replacing the reservoir bag of the Jackson-Rees modified Ayre's T-piece with the pressure present ventilator is an excellent device for pediatric anesthesia.
