Comparison of Left Ventricular Ejection Times Measured from Carotid Arterial Sphygmogram and Digital Plethysmogram

Left ventricular ejection times were measured from indirect carotid arterial sphygmograms and digital plethysmograms in 118 healthy males and 106 healthy females. The carotid-derived left ventricular ejection time, which was generally accepted as a standard measurement, was shorter than the other in both sexes. However, there was a significant correlation between these two measurements in males and females. This suggests that the left ventficular ejection time obtained from the digital plethysmogram could provide a comparable information to that of the carotidderived one.

Horseshoe Kidney associated with Giant Hydronephrosis / 대한비뇨기과학회지

A case of 26 years old male having horseshoe kidney associated with giant hydronephrosis due to aberrant vessel was presented with a brief review of the literatures. The patient was managed by division of isthmus and nephrectomy with good result.

Respiratory Effects of Acute Coronary Embolism

Respiratory effects of acute coronary embolism were studied in mongrel dogs. Coronary embolism was produced by Agress's method and respirtory effects were observed for two hours. In the experimental group, in which coronary embolism was produced, there were relative decreases in respiratory rate and arterial oxygen saturation along with relative increases in tidal volume, minute ventilation, ventilation equivalent and arteriovenous oxygen difference compared to those in the control group. However, differences in these various measurements between tow groups, those in tidal volume and arterial oxygen saturation, have greatly diminished in two hours. These facts suggest that changes in respiratory rate, minute ventilation, ventilation equivalent and arteriovenous oxygen difference in the experimental group are early but short-lasting responses to acute coronary embolism, whereas changes in tidal volume and arterial oxygen saturation occur early and last longer.

Hepatic Blood Flow in Various Hepato-biliary Diseases

Hepatic blood flow was studied by the determination of the fractional clearance of intravenously administered colloid 198Au in 35 cases of normal subjects, 36 cases of liver cirrhosis, 18 cases of primary cancer of the liver, seven cases of liver abscess, five cases of hepatitis and 10 cases of hepato-biliary diseases. There was no appreciable difference in the mean values of the fractional clerance between the normal subjects and biliary tract diseases. On the contrary, it was diminshed in liver cirrrhosis, primary cancer of the liver, hepatitis and liver abscess compared with that in the normal subjects, and the diminution in liver cirrhosis and primary cancer of the liver was significant, and also the fractional clearance in the former was significant, and also the fractional clearance in the former was significantly smaller than that in the latter. However, the individual datum both in the normal control and diseased groups showed a marked overlapping among them except that in the normal subjects and biliary tract diseases the fractional clearance was above 0.10 in almost all cases. In cirrhosis of the liver there was no relationship between the fractional clearance and liver functions.
