N/A The author studied on acute gastritis of antrum diagnosed with gastroscopy, for 88 cases who had visited Department of lnternal Medicine, Pusan National University Hospital from July 1982 to June 1983. Detailed studies were made of clinical and endoscopic findings in 88 patients, and histopathologic findings in 15 patients whose biopsies were possible among 88 patients. The results were as follows; 1) The sex distribution of the 88 patients was observed such as 72.7% in male and 2.73% in female with ratio of 2.7: 1(male female). In age distribution, third decade(33. 3%) was most frequent and the remaining was in the following order 4th, 5th, 6th, 7th decade respectively. And acute gastritis of antrum occurred most frequently in December. 2) The suspected causes were drug ingestion in 15.9% stress in 13.6%, alcohol in 10.2% and unknown in 46.6%. 3) Clinical manifestations of 88 cases undergone gastroscopy were abdominal pain(96.6%), nausea(60.2%) and abdominal discomfortness(54.5%). The author clinically classified 88 patients into three types based on endoscopic findings. The frequency of each types was edematous gastritis in 34.1%, hemorrhagic erosive gastritis in 48. 9% and ulcerative gastritis in 17.0% respectively. 4) Endoscopic features were as follows; In edematous type, there observed edema of mucosa and narrowing of the antrum due to marked swelling of the mucosal folds, extending from the antrum up to the region of the angulus. These findings were subsided in 1~2 weeks. In hemorrhagic erosive type, edematous thickening of the mucosal folds were extended from the antrum up to the region of the angulus in addition to hemorrhage and erosion which normalized in 1 week. In ulcerative type, there also observed mucosal edema, erosion and hemorrhage. Hemorrhage was disappeared in 1 week, but one or more ulcerations were observed on antrum. 5) Histopathologic features were as follows; slight edema and hypergjg of the mucosa were observed in the edematous type, showing no other characteristic change. Characteristic changes in hemorrhagic erosive type were hemorrhage, necrosis and neutrophil infiltration. In the early stage of the ulcerative type, the histologic changes were very similar to those in the hemorrhagic erosive type. Ulcer formation was observed on the 4-7th day of the onset.

저자들은 16예의 삼첨판 폐쇄 부전증 환자에서 연속파형 Doppler 심초음파로 수축기 역류의 최대속도(PV), 가속시간(AT), 감속시간(DT) 및 감속율(DR)을 계측하여 심도자술에 의한 우심실 및 폐동맥 수축기압과 비교하여 다음과 같은 결과를 얻었다. 1) Doppler 법으로 구한 삼첨판 수축기 역류의 PV는 254.0±71.0 ㎝/sec, PG는 26.9±12.8 mmHg였으며 심도자술로 측정한 우심실과 우심방 사이 수축기 압차는 30±13.9 ㎜Hg였으며 이들 사이에 상관관계는 상관계수 0.84(p<0.001), 0.87(p<0.001) 이었다. 2) Doppler 법으로 구한 삼첨판 수축기 역류의 PV 및 PG와 심도자술로 측정한 우심실압 사이의 상관관계는 0.86(p<0.001), 0.87(p<0.001)의 정상관관계 였으며, 폐동맥압과는 상관계수가 0.82(p<0.001), 0.87(p<0.001) 이었다. 3) 삼첨판 역류의 Doppler signal에서 Deceleration rate는 PV, PG 및 심도자술로 측정한 우심실과 우심방 사이의 압차와는 상관계수 0.90(p<0.001), 0.92(p<0.001), 0.82(p<0.001)의 정상관 관계에 있었다. 이상의 결과 삼첨판 폐쇄 부전증에서 Doppler 법으로 계측한 peak velocity, pressure gradient와 Doppler signal의 deceleration rate로써 우심실 및 폐동맥압을 추정 할 수가 있었다. To determine noninvasive estimation of systolic right ventricular and pulmonary artery pressure by continuous wave Doppler echocardiography. We analyzed continuous wave Doppler echocardiography and cardiac catheterization data in 16 patients with tricuspid regurgitation undergoing right heart catheterization. Peak velocity of systolic tricuspid regurgitation flow by continuous wave Doppler echocardiography was 254.0±71.0 ㎝/sec and calculated pressure gradient between right ventricle and atrium was 26.9±12.8 ㎜Hg. Peak velocity and pressure gradient of systolic tricuspid regurgitation flow in continuous wave Doppler echocardiography significantly correlated with systolic right ventricular pressure (r=0.84 p<0.001, r=0.87 p<0.001) and systolic pulmonary artery pressure (r=0.82 p<0.001, r=0.87 p<0.001) measured by right heart catheterization. Deceleration rate of systolic tricuspid regurgitation flow significantly correlated with peak velocity (r=0.90 p<0.001) and pressure gradient (r=0.92 p<0.001) by continuous wave Doppler echocardiography also significantly correlated with systolic pressure gradient (r=0.82 p<0.001) between right ventricle and right atrium measured by right heart catheterization. In conclusion, we could noninvasively estimate systolic right ventricular and pulmonary artery pressure in the patients with tricuspid regurgitation by analyzing peak velocity, pressure gradient and deceleration rate by continuous wave Doppler echocardiography.
