The purpose of this study was to know the effect of short termed fasting on the usage of metabolic energy sources and the metabolic differences between non-athletic and athletic subjects. Subjects were divided into non-athletic and athletic group and exercise was loaded on both groups after feeding and fasting. Exercise was loaded by a treadmill running at the speed of 8 km/hour for 30 minutes in both groups. The experiment yielded following results. In the fed state, the level of plasma FFA increased markedly after 15 and 30 minutes of exercise compared with it's level of pre-exercise period in both groups. In the fated state, the level of plasma FFA in non-athletic group increased steadily according to the duration of exercise, while it's level in athletic group showed no changes. At pre-exercise period, the level of plasma FFA was higher in fasted state than fed state. Immediately before the exercise and 15 and 30 minutes after the exercise, blood for the determination of plasma free fatty acid (FFA), glucose, triglyceride (TG) and cholesterol was sampled from antecubital vein, and simultaneously heart rate was measured. In the fed state, the level of plasma glucose was increased mildly according to exercise, and in the fasted state it's level increased according to exercise in both groups also. In the fasted state, the level of plasma TG was lower than that in the fed state. The level of plasma TG and cholesterol in the fed state was no changed by the exercise from the pre-exercise period. The level of plasma cholesterol in athletic group had tendency to lower than that in non-athletic group. Heart rate increased markedly according to exercise in both groups, but the athletic group's increasing rate of heart rate was lower than the non-athletic group's heart rate increased according to exercise and athletic groups heart rate increased early period of exercise, but did not change during latest post-period of exercise.

Eighty-eight patients who presented with a variety of head and neck symptoms were examined with intravenous oritraarterial digital subtraction angiography (IV or IA DSA), using the DSA equipment developed by Seoul NationalUniversity Hospital. A grading system was used to evaluate the ability of DSA to answer specific diagnsoticquestions. Diagnostic information without need of further study was obtained in 71% with IV DSA, in 86% withaortic arch DSA and in 81% with selective arterial DSA, showing a total of 79% of diagnostic accuracy with DSA. Itis concluded that IV DSA is useful in the evaluation of the cervical carotid and vertebral arterial disease, andpituitary mass lesion, while IA DSA is useful in the evaluation of the cervical carotid and vertebral arterialdisease, and pituitary mass lesion, while IA DSA is useful in the evaluation of most of the intracranial lesions,spinal arteriography and intra-arterial embolization. DSA is both an accurate and safe imaging modality in thestudy of head and neck diseases.

Glanzmann's thrombasthenia is a rare autosomal recessive hemorrhagic disorder characterized by prolonged bleeding time, ad deficient or absent clot retraction in the presence of normal platelet count. The major underlying abnormality in this disease is grossly defective first-phase aggregation of platelet, which are unresponsive to ADP or other platelet agonists such as epinephrine, collagen, thrombin in any concentration. This disability is caused by a decrease or absence of the platelet membrans glycoprotein IIb-IIIa complex, a member of the integrin family of adhesive receptors involved in cell-cell and cell-matrix fibronectin, and vitronectin On the development of surface labeling technique, a variety of biochemical techniques such as radioimmunoassay, crossed immunoelectrophoresis and SDS-PAGE have been used to study the structure and the function of platelet membrane glycoproteins, and to detect the platelet functional defect. But all of these techniques demand a relatively large amount of homogeneous paletelet population that requires manipulation through isolation and washing procedures before analysis. In order to eliminaste such an intricate procedure, we have applied method for analyzing platelet surface components in whole blood using monoclonal antibody and flow cytometry to recognize the absence of severe reduction of platelet membrane glycoprotien llb-llla complex. Platelet analysis by flow cytometry is a successful alternative rapid diagnostic technique for Glanzmann's thrombasthenia patients as well as well as for carriers of this disease. Fow cytometry technique provides a sensitive tool for investigating platelet functional defects caused by altered expression or deficiency of platelet surface proteins.

A modern development of ambulatory ECG monitoring gave great advances in the diagnosis and evaluation of various cardiac conditions. Fifteen cases of ischemic heart disease, 11 cases of nonischemic heart disease, 5 cases of noncardiac disease and 9 cases of normal healthy subjects were studied from January 1980 to July 1981 in national Medical Center, with the following results: 1) The heart rate was decreased during night time, with less decreasing tendency in patients with ischemic heart disease. 2) Among 30 cases, including 12 patients with ischemic heart disease, who didn't show arrhythmia on routine 12 lead ECG, 12 cases, including 6 patients with ischemic heart disease, showed arrhythmia on Holter monitoring. 3) Among 5 cases with ischemic heart disease who showed premature ventricular contraction on day time monitoring, 2 cases didn't show premature ventricular contraction on nigh time monitoring. 4) The S-T segment and T wave were changed during night time in 2 cases with ischemic heart disease and in 2 normal subjects. From these results, we could assert that Holter monioring or ambulatory ECG tracing would be a good method for diagnosis and evaluation of ischemic heart disease, and other cardiac conditions. Several another studies with this equipment have to be performed and would give more distinctive outcomes.

Since Thomas et al reported the first instance of successful removal of a broken intravascular guidewire without surgical intervention by using a bronchoscopic forceps in 1964, there have been a number of nonsurgical removal of intravascular or intracardiac foreign bodies using the bronchoscopic forceps, loop snare or basket stone catchers. We experienced a successful retrieval of accidentally broken subclavian puncture catheter from right atrium in 76 year old male patient with cerebral infarction admitted to this hospital on May, 1989. By percutaneous catheterization via right basilic vein, using a loop snare which is modified manually by guidewire for PTCA(USIC(R) Teflon coated PTCA Guide wire : ".014"), we removed successfully foreign body from right atrium. Therefore, we report a case of nonsurgical retrieval of foreign body from right atrium with the review of the literature.
