N/A Background: Since the concept of peak aortic blood velocity and peak acceleration by Rushmer et al, doppler echocardiography based on the hemodynamic theory has developed as a new noninvasive measure for the evaluation of left ventricular systolic function during the ejection time. Method: The left ventricular ejection force over the acceleration time and the intrinsic component of the left ventricular load at peak acceleration, measured by pulsed wave doppler echocardiography, were compared in 10 patients with idiopathic dilated cardiomyopathy with 9 normal controls. Results: 1) The fractional shortening, peak aortic blood velocity, mean acceleration and ejection force over the acceleration time were significantly lower in the dilated cardiomyopathy group than control group (control vs DCM =33.88±4.75% vs 17.21±5.99%, p<0 001, respectively). 2) By the regressin in the % fractional shortening,, measurement of ejection force over the acceleration time was more beneficial than measurement of peak aortic blood velocity and mean acceleration in assessing the left venticulat systolic function(r=63, 0.49 and 0.55 respectively). 3) The left ventricular intrinsic wall stress showed no significant statistical difference between 2 groups, but intrinsic σm/total σm ratio was significantly lower in the dialated cardiomyopathy group than control group (control vs DCM = 4.36±1.889: vs 1 88% vs 1.84±0.88% p<0.005). Conclusion: The measurement of the ejection force over the acceleration time and the left ventricular intrinsic wall stress/total ventricular load ratio were beneficial in evaluating the ejection hemodynamics during the left ventricular systole.

심와부 동통을 주소로 내원한 31세 환자에서 발견된 이소성 췌장 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Heterotopic pancreas is an aberrant rest of well-developed normally organized pancreatic tissue that lacks anatomic and vascular continuity of the main body of pancreas. About 80% of heterotopic pancreatic lesions found in the stomach are located in pylorus or in the antrum within 5-6cm from pylorus. Although heterotopic pancreas is noted most often as an incidental findings at autopsy and during surgery for other conditions, it is capable of producing symptoms depending on the site of lesions and may reflect the whole range of pathology affecting pancreatic tissue. We have recently experienced a case of heterotopic pancreas on the pylorus, anterior wall in the body. Excision was done and he was discharged with well-being state.

The gastrointestinal polyp is a premalignant lesion in varying degree. According to the size, the pathology and the location of polyps, it should be removed. Polyps in the gastrointestinal tract can be removed by surgical excision, electrosurgery, cryotherapy, regional radiotherapy and laser therapy with some limitations. Considerable advance in therapeutic endoscopy as well as in diagnostic endoscopy along with newly developed instruments has now made it possible to excise gastrointestinal polyps by means of high frequency generator. We have underwent endoscopic polypectomy, strip biopsy and $quot;O$quot; ring ligation on gastric polyps in 112 patients who visited in this hospital from July l988 to January 1994, and the clinical characteristics including histopathology has been evaluated. Removed polyps were variable in size from less than 0.5 cm up to 4cm. Finally, we concluded that endoscopic polypectomy is a safe and relativly simple procedure and postpolypectomy complication can be considerably reduced by conservative antiulcer therapy.

위암의 호발연령은 50∼60대로 알려져 있으나 약년자에서도 위암의 발생빈도가 증가하고 있다. 저자들은 만 7년간 부산백병원 내 과학교실에서 경험한 약년자위암 115례에 대한 임상적 고찰을 하였다. 115 cases of stomach cancer under the age of 35 years, seen in the period 1984 to 1990 are reviewed. The results were as follows 1) The incidence of stomach cancer under 35 years was 7.6% in all gastric malignancies. and male to female ratio was 1:1.3 2) Most of symptoms were nonspecific and epigastric pain was major symptom(89.7%). About 57.8% of the patients visited hospital within 3 months after onset of symptoms, and average duration of symptoms were 7.8months. 3) Physical examination revealed epigastric tenderness, anemia, ascites, and palpable mass in decreasing order of frequency 4) The majority of tumors located in the lesser curvature of body and antrum 5) Endoscopic findings in 91 cases of advanced stomach cancer were type III, type Iv, type II, type I in decreasing order of frequency, and the most common type of early stomach cancer were IIc 6) Histopathologic finding revealed that all cases were adenocarcinoma, and 88.7% (102 cases) showed low grade differention 7) Forty four of 55 cases of operable cancer underwent radical operation for cure
