Recent studies have shown that urinary excretion of water-soluble vitamins reflects their intake in humans. However, some have reported that physical characteristics and urine volume may affect the amount of vitamin compounds found in urine. We hypothesized that physical characteristics and urine volume could affect urinary excretion of B-group vitamins.(More)
The effects of rat atrial natriuretic peptide (rANP) on blood volume (BV) were determined by the continuous measurement of BV, mean arterial pressure (MAP), and central venous pressure (CVP). Immediately after a single-bolus injection of rANP-(1-28), 1 nmol/100 g body wt, in conscious rats, BV began to decrease. Peak reduction of -0.22 +/- 0.03 ml/100 g(More)
A patient with extrahepatic portal vein aneurysm with massive thrombosis, congenital in nature, is reported. Reconstructed images using curved reformation software and three-dimensional images from helical CT were useful to delineate the shape of the portal vein aneurysm and extension of the thrombi.
Seven rats were exposed to a hot environment (36 degrees C) for about 5 h to induce thermal dehydration. They were allowed to recover from their fluid loss; both tap water and 1.8% NaCl solution were provided simultaneously as drinking fluids. In the recovery stage, these animals initially consumed low NaCl solution (about 41 mEq/l) for the first 90 min and(More)
A new continuous measuring system for blood sodium concentration and blood volume in conscious rats is described. A small extracorporeal circulation was made and the blood was passed through a sodium sensitive glass electrode and a gamma-counter. Applying the system to conscious rats, the effect of various salinities of drinking water was detected from the(More)
A case of left anterior and middle cerebral arterial occlusion with angiographic features similar to Moyamoya disease was reported. IMP SPECT of the patient revealed the success of bypass surgery clearly. The patient complained of transient right hemiparesis with aphasia 4 times. The cerebral arteriography disclosed occlusions of left anterior and middle(More)
Changes in blood volume (BV) and Na+ concentration of plasma ([Na+]) were measured continuously during recovery from thermal dehydration in rats. At least 5 days prior to the experiments rats were cannulated into both the jugular vein and the descending aorta. After thermal dehydration (DBT: 36 degrees C, RH: 20%) amounting to approximately 6% of body wt,(More)
