The aim of this study was to quantitatively estimate the effect of hypertension upon the left ventricle, using the systolic time intervals. The subjects for this study consist of 72 hospitalized hypertensive patients including 38 males and 34 females. The measurements of the systolic time intervals were obtained from simultaneous high speed recording(100mm/sec) of an electrocardiographic lead best displaying the onset of left ventricular depolarization, a carotid pulse tracing, and a phonocardiogram best displaying the initial high frequency vibrations of the aortic valve closure sound. All data were corrected for heart rate and sex using the regression equations of Weissleretal. The results were follows: 1) As the diastolic blood pressure increased, shortening of left ventricular ejection time index and prolongation of preejection period index and PEP/LVET ratio were significant. 2) As the electrocardiographic findings related to hypertension became severe shortening of left ventricular ejection time index and prolongation of preejection period index and PEP/LVET ratio were significant. 3) As the hypertensive retinopathy became severe, shortening of left ventricular ejection time index and prolongation of preejection period index and PEP/LVET ratio were significant. It was suggested that the measurement of the systolic time intervals are useful in assessing the effects of hypertension upon the left ventricular function and in detecting early recognition of cardiac dysfunction in hypertension, even though not necessarily associated with overt heart failure.

PURPOSE: To evaluate the MR appearance of the accessory hepatic veins. MATERIALS AND METHODS: The study included 87 consecutive patients for whom abdominal MR images were obtained. The subjects who had liver lesion or hepatic vascular abnormalities were excluded. Couinaud classified accessory hepatic veins into inferior and middle right hepatic veins. Our major interests were evaluation of the incidence, morphology, and location of the accessory hepatic vein. RESULTS: Inferior right hepatic vein was demonstrated in 43 out of 87 patients(49%). The morphology was linear in 35 patients(80.5%), and V-shaped in 8 patients(19.5%). In 40 patients(93%), the inferior right hepatic vein was located in the posteroinferior aspect of the right lobe. Middle right hepatic vein was demonstrated in 7 out of 87 patients(8%). All were single linear in morphology, combined with the inferior right hepatic vein, and located between the right hepatic vein and inferior right hepatic vein. CONCLUSION: The accessory hepatic vein was demonstrated in 49% among the Korean adult population, and was located in posteroinferior portion of the liver, in 93%.

PURPOSE: To evaluate the pattern of distant lymph node metastasis in colorectal carcinoma and its correlation with distant organ metastasis. MATERIALS AND METHODS: We retrospectively reviewed abdominal CT scans of 46 patients with pathologically proven colorectal carcinoma. RESULTS: The incidence of distant lymphadenopathy in colorectal carcinoma was 30.4%(14/46). The most commonly involved distant lymph node was the left paraortic lymph node below the renal hilum(9/25). The most common type of distant lymphadenopathy was solitary type(7/14) and all of these lymphadenopathies were noted in the left paraortic lymph node below the renal hilum. Six cases of left sided colorectal carcinoma showed left paraortic lymphadenopathy with solitary type. The incidence of distant organ metastasis was 17. 4%(8/46) and markedly increased if distant lymphadenopathy was multiple and confluent, or confluent type(5/7). CONCLUSION: The incidence of distant lymphadenopathy in colorectal carcinoma was not high and the most common lymphadenopathy was the left paraaortic lymph node with solitary type below the renal hilum. The possibility of distant organ metastasis was high if distant lymphadenopathy was multiple and confluent, or confluent type.

Clinical presentation of supplementary motor area (SMA) syndrome includes complete akinesia of the contralateral side of the body and mutism, with secondary recovery of neurologic deficit. Multi-joint coordination is frequently impaired following the development of a brain lesion and is generally restricted by abnormal patterns of muscle activation within the hemiparetic limb, clinically termed muscle synergies. However, no work to date has confirmed this observation with the aid of objective methods, such as gait analysis, and the development of reflex pattern has not been suggested as a possible cause. We describe two unusual cases of flexor synergy after tumor resection of SMA lesions.

In order to study the effects of aminoglycosides on leukochemotaxis in rats, the degree of leukocyte infiltration and differential leukocyte count were observed at the experimentally inflamed tissue by incision of the skin and the application of endotoxin subcutaneously after the administration of gentamicin and streptomycin respectively. The results obtained were as follows. 1) In the control group treated with physiological, saline, the infiltration of leukocytes was relatively scant in the first nne hour, conspicuously increased three hours later, and persisted for 24 hours. 2) In the gentamicin and streptomycin treated groups, infiltration of leukocytes was srnall in number in the first hour. There after it gradually increased over a period of time. However it was a little less in the gentamicin and streptomycin injected group compared with the control. 3)In the control group, about 90% of the infiltrated cells was neutrophils up to three hours. However 24 hours later, the neutrophils reached about 40%. On the other hand, monocytes and lymphocytes were 4% in the first hour, and after 24 hours the monocytes was 19 to 24% and lymphocytes were 31 to 36%. 4) In the gentamicin and streptomycin injected grougs, about 90% of the infiltrated cells was neutrophils for the first three hours. The numbers gradually decreased to 56-66% and 51~54% after 24 hours, respectively. The percentage of both monocytes and lymphocytes was 2~4% after ome hour, and increased to 15~29 and 17~29% after 24 houre, respectively.
