The volumetry by cineangiocardiography is known to have the most diagnostic and prognostic value in theevalutaion of various valvular heart diseases and ischemic heart diseases. Athough many authors favor thearea-length method for the voulmetry of left ventricle, 45degrees RAO projection seems to be more simple,inexpensive and acurate technique, considering the positional relationship of cardiac valves and obliquity of thelong axis of left ventricle within the chest cage. Authors present the anatomical, geometrical and radiologicalbasis for the superiority of 45degrees RAO projection by analyzing 20 normal heart specimen and 115cineangiocardiograms of valvular heart disease, and the results as follows; 1. Blood flow and motility of themitral and aortic valves can be more clearly demonstrated by 45degrees RAO projection than by AP view. 2. The longdiameter of left ventricular silhouette made 45degrees RAO projection reflects 90% or more of real diameter. 3. InRAO 45degrees position, patient's left nipple is optimal and convenient level for the ruler offering accuratemagnification coefficient of left ventricle. 4. Ejection fration after the extrasystole is exaggerated regardlessof the left ventricular function, so it is desirable to exclude the 2 or 3 beats after extrasystole.

An experimental study on the vascular alternations of the kidney following biopsy procedure was carried out in 47 kidneys from 28 rabbits to clarify their nature and frequency by renal arteriography and microangiography together with histopathologic investigation. Renal arteriography and microangiography were perforemd immediately 2 days, 1 week, and 2 weeks after percutaneous biopsy and the findings were correlated with histological nature. The results are summerized as follows; 1. Important biopsy injuries verified by renal arteriography and microangiography were arterial spasm, perfusion defect, arteriovenous fistula, injury to vasa recta and renaltubules, intrarenal and extrarenal extravasation of contrast media, and arterial obstruction, in order of frequency. 2. Artierial spasm observed in majority of the cases were relieved during the period of 2 weeks. 3. Detectability of perfusion defect was 57% and 72% by angiography and microangiography, respectively, and this perfusion defect seemed to be mostly caused by renal infarction due to vascular injury, such as arteriovenousfistula, arterial obstruction and other vascular injuries. 4. Arteriovenous fistula was detected in 28% byangiography and 50% by microangiography. Many of the arteriovenous fistula appeared to be closed spontaneously within a week. Above findings suggest that renal biopsy procedure results in various degree of vascular injuries with their sequential modification, and that microangiography is assumed the most effective approach in analysisof biopsy injuries such as small arteriovenous fistula, perfusion defect, injury to vasa recta and renal tubules, overcoming the limitation of traditional angiography.

PURPOSE: This study was performed to evaluate the features of pulmonary lobes and fissure in Korean and to compare with the previous results. MATERIALS AND METHODS: HRCT scans of 82 healthy Korean adults, performed with scan interval of 1.5/2.0 cm, were reviewed. RESULTS: Located mostly on inner aspect, incidences of incomplete oblique and horizontal fissure were 60% (Rt 48%, Lt 39%) and 51% respectively, lower than 70--80% and 60--75% of western studies. Superolateral oblique fissure, inferior accessory fissure, left horizontal fissure and other accessory fissure were shown in 1%, 13%, 7%, and 8% respectively. Lower lobe upper part faced laterally (Rt 91%, Lt 82%) while lower part faced medially (Rt 61%, Lt 79%). Right middle lobe ws highest posteromedially (49%) and was convex (97%). CONCLUSION: Features of pulmonary lobes and fissure in Korean were similar to the results of previous reports but with lower incidence of variation.

This study was carried out to investigate air pollution by total suspended particulate(T.S.P.), benzene soluble matter and benzo(a)pyrene in Seoul city. The sampling areas were divided into commercial(Kwang Hwa Moon), industrial(Ku Ro Dong) and residential area(Shin Chon). Sampling was undertaken by High Volume Air Sampler for four seasons from January 1977 to November 1977. The T.S.P. was extracted with Soxhlet apparatus by benzene and benzo(a)pyrene was separated by column chromatography and thin layer chromatography. The concentrations of benzo(a)pyrene were measured by means of fluorophotometer, and following results were obtained. 1. Arithmetic average concentration for 1-day averaging time of total suspended particulate were 275.6 microgram/m3 in Kwang Hwa moon, 325.9 microgram/m3 in Ku Ro Dong and 193.0 microgram/m3 in Shin Chon. 2. The seasonal variance of total suspended particulate at Ku Ro Dong and Shin Chon were 102.7 microgram/m3 99.6 microgram/m3 respectively and at Kwang Hwa Moon 39.9 microgram/m3. And the concentration of autumn is higher than of that spring at Ku Ro Dong and at Shin Chon, but at Kwang Hwa Moon, the seasonal variance is very little. 3. The concentrations of 50% frequency from geometric mean for 1-day averaging time were 264 microgram/m3 and 178 microgram/m3 at Kwang Hwa Moon, Ku Ro Dong and Shin Chon. And geometric standard deviation were 1.27, 1.38 and 1.41 respectively. 4. The concentrations of benzene soluble mater were 26.9 microgram/m3 Kwang Hwa Moon, 22.7 microgram/m3 at Ku Ro Dong and 15.5 microgram/m3 at Shin Chon, and the ratios to the T.S.P. were 9.8%(range 5.6-14.8%), 7.0%(range 2.4-14.4%) and 8.0%(range 5.5-22.1%) respectively. 5. The concentrations of benzo(a)pyrene were 8.5 microgram/m3 (range 0.8-29.9 microgram/m3 ) at Kwang Hwa Moon 10.9 microgram/m3 (range 1.1-52.0 microgram/m3 ) at Ku Ro Dong and 5.8 microgram/m3 (range 1.5-11.4 microgram/m3) at Shin Chon. 6. The results of this investigation were relatively high in compared with the recommended standards of suspended particulate in air of U.S. Environmental Protection Agency and observed levels of Benzo(a)-pyrene in U.S. city.
