Complications after surgical treatment of trochanteric fracture such as varus deformity or delayed union are frequent and there are many difficulties to maintain the stability of fragments because of the cortical deficit or comminution on medial aspect of the neck and posterior trochanteric fragment. Evans, Dimon, Sarmiento and others suggested several methods of internal fixation, furthermore it is attempted recently to reduce the fragments anatomically with sliding compression hip screw and plate. 31 cases of interal fixation on trochanteric fracture were carried out from March, 1972 to February 1979 at the Orthopaedic Department of Seoul Adventist Hospital and their comparable results were as follows. 1. Acceptable placement of metals was noted 2 cases of 6 cases in Smith-Petersen nail with Thornton plate fixation, 2 cases out of 8 cases in Smith-Petersen nail with McLaughlin plate fixation and 9 cases out of 14 cases in sliding compression hip screw and plate fixation. 2. Complications after internal fixation such as varus deformity and delayed union were noted 1 case out of 3 cases in multiple pinning, 3 cases out of 6 cases in Smith-Petersen nail with Thornton plate fixation, 4 cases out of 8 cases in Smith-Petersen nail with McLaughlin plate fixation, 4 cases out of 14 cases in sliding compression hip screw and plate fixation. 3. Required weeks in union were 18 weeks in Multiple pinning, 20 weeks in Smith-Petersen nail with Thornton plate fixation, 25 weeks in Smith-Petersen nail with McLaughlin plate fixation and 16 weeks in sliding compression hip screw and plate fixation. 4. There are few complications in treatment of trochanteric fracture with surgical procedure using Sliding compression hip screw and plate.

Intravascular injection of hydrogen peroxide produces oxygen microbubbles suitable for echocardiographic contrast enhancement. To evaluate the effect of a method of myocardial contrast 2-D-echocardiographic delineation of myocardium during acute coronary occlusion, injection of a fresh mixture of 2ml of 0.2% H2O2 and 1ml of heparinized dog blood into aortic root were made in 12 poenchest dogs 10 minutes after occlusion of left anterior descending coronary artery distal to the first diagonal branch and left ventricular short axis 2-D echocardiographic images at the midpapillary muscle level were obtained. On injection of H2O2 blood mixture normally perfused myocardium was enhanced in echodensity but the area of malperfusion did not change in echodensity. The borderlines between the area of normal perfusion and malperfusion was well delineated. The malperfused area measured at mid papillary muscle level by planimetry area method was 29.7+/-6.0% and 32.6+/-6.7% by endocardial circumferential length method. There was a linear correlation between planimetric estimate of area of malperfusion by H2O2 contrast echocardiography and visual determination of regional wall motion abnormality by 2-D echocardiography(r=0.93, P<0.001). There was no change in heart rate before, during and after H2O2 injection. Infection of H2O2 blood mixture caused bradycardia(8.3%), second degree A-V block(16.6%) and ventricular fibrillation(8.3%). H2O2 clearance was achieved in 3-10 minutes. These findigs suggest that H2O2 enhanced myocardial contrast ehocargiography using 2ml of 0.2% H2O2 and 1ml of blood muxture is an accurate, reproducible, real-time in vivo method of quantifying the extent of myocardial perfusion defect during acute coronary occlusion in dog.

To investigate frequency of painful and/or silent myocardial ischemia(SMI) determined by ECG ST-segment depression(more than 1.0mm depression for 0.08 second after J point over 60 seconds) during unrestricted daily activities, 24-hour dynamic ECG was performed in 19 patients(11 males, 8 females) with chronic stable angina pectoris, aged 57.4 years(44 to 73 years). During 456 hours of recording, there were 154 episodes of SMI. Of these, 139 episodes(90.3%) were silent and 15 episodes(9.7%) accompaned chest pain. The higher incidence of SMI than previously published data is probably influenced by 1 patient who disclosed 56 episodes (excluding this, SMI 84.7%). Sixty one percent of episodes of SMI occurred during light activities such as slow walk, hand labor, eating or at rest(sitting at ease), smoking and sleep, and 39% during more strenuous activites such as walk, climbing stairs and physical exercise. In contrast, most of the painful myocardial ischemia(PMI) developed during climbing stairs, walk and physical exercise. Heart rate during episodes of SMI varied ranging from 85.2+/-13.7/min at rest to 115.5+/-19.2/ min druing climbing stairs. Mean ST-segment depressions during episodes of SMI and PMI were 2.0(1.0-4.0)mm and 2.6(1.2-7.0)mm, respectively, in 6 patients who disclosed both SMI and PMI on 24-hour ECG recordings. However, frequency of ischemic episodes was higher(9.0 vs 2.5/day) and duration was longer(13.8min vs 3.0min) in SMI. These findings indicate that transient SMI in patients with chronic stable angina pectoris occurs more frequently than painful myocardial ischemia. In addition, SMI develops during activities that increase heart rate(increased O2 demand) as well as during activites that do not increase heart rate(decreased O2 supply). Therefore, both O2 demand and supply mechanisms may be involved in the pathogenesis of transient SMI in Patients with chronic stable angina pectoris.
