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.

BACKGROUND: Induction of general anesthesia with tracheal intubation and skin incision are potent stimuli that can induce increased sympathetic activity, heart rate and blood pressure. We compared the hemodynamic response and catecholamine concentration during general anesthesia with intravenous clonidine pretreatment, a centrally acting -2 adrenoceptor agonist, and without pretreatment. METHODS: Forty ASA I or II patients aged from 20 to 60 years undergoing elective surgery were randomly allocated to two groups. In group I, 5 ml of 0.9% normal saline as control administered intravenously 10 minutes before induction of anesthesia, and anesthesia was induced with thiopental sodium, succinylcholine and maintained with N2O (2.5L/min)-O2 (2.5L/min)-enflurane (1.3~1.8 vol%). In group II, 4 g/kg clonidine diluted in 5ml of normal saline administered intravenously 10 minutes before induction of anesthesia, and anesthesia was induced with thiopental sodium, succinylcholine and maintained with N2O-O2-enflurane (0.5~1.0vol%) and 2 g/kg/hr clonidine was continuously infused. We measured blood pressure, heart rate and plasma catecholamine at preinduction, 1 minute after intubation (T1), 1 (T2) and 30 minutes after skin incision (T3) and compared with group I. RESULTS: There was statistical significance in systolic and diastolic pressure at T1 between two groups. There was statistical significance in heart rate, epinephrine and norepinephrine at T1, T2 and T3 between two groups. CONCLUSION: The elevation of blood pressure, heart rate and plasma catecholamine accompanying tracheal intubation and skin incision may be prevented by administration of intravenous clonidine.

With development of immunochemical methods for anlysis of serum proteins, quantitative determination of serum immunoglobulin levels and purification of them have been made possible in recent years. There are numerous reports about immunoglobulin levels in various diseases. A search of the literature reveals very few reports of quantitative immunoglobulin determinations in allergic dermatoses. The present study was conducted to find quantitative changes of serum immunoglobulins in a few allergic dermatoses. To quantify the IgG, IgA and IgM, one hundred and two sera were analysed form 30 normal control group, 30 contact dermatitis patients, 12 stopic dermatitis patients and 30 urticaria patients by modified Oudin's capillary tube method. The results are as follows. 1.In contact dermatitis the IgG was significantly increased to compare with control group(p<0.01) 2.In atopic dermatitis the IgA was significantly increased to compare with control group(p<0.01) 3.In urticaria the IgG was increased (p<0.05) 4.The IgM has no differences between allergic dermatoses and control group.
