The objective of this study was to determine whether subacute ruminal acidosis (SARA) could be diagnosed by continuous measurements of the reticular pH, as compared with the ruminal pH, using healthy cows fed a control diet and SARA cows fed a rumen acidosis-inducing diet. The reticular and ruminal pH were measured simultaneously by a radio transmission pH(More)
Between 1990 and 2004, 149 patients underwent esophagectomy with thoracotomy at our institution. Because the retention of a nasogastric tube postoperatively impedes expectoration, this practice was abolished in 1997, in order to reduce the risk of respiratory tract infection (RTI). Since 1998, we have instead performed gastrostomy for decompression. In this(More)
BACKGROUND Application of a multisample method using inulin to estimate glomerular filtration rate (GFR) in cats is cumbersome. OBJECTIVES To establish a simplified procedure to estimate GFR in cats, a single-blood-sample method using inulin was compared with a conventional 3-sample method. ANIMALS Nine cats including 6 clinically healthy cats and 3(More)
To compare glomerular filtration rate (GFR) estimated by a single blood sample method, the non-ionic contrast medium iodixanol (40 mg I/kg) and the standard GFR tracer inulin (50 mg/kg) were co-administered as a bolus intravenous injection to 12 cats, followed by blood collection 60 and 90 mins later. Serum iodixanol and inulin concentrations were measured(More)
To evaluate serum clearance of iodixanol, applicable to the estimation of glomerular filtration rate (GFR), clinically healthy and experimentally-induced nephropathy calves were prepared. Iodixanol was administered intravenously at 40 mg I/kg, and blood was withdrawn 60, 120, and 180 min later. Serum iodixanol concentration was determined by(More)
A 74-year-old man with anemia visited our hospital. When he was 42 years old, he was diagnosed with duodenal ulcer and underwent gastrectomy with Billroth II construction. A gastrointestinal endoscopic examination revealed an ulcerative lesion at the remnant stomach, and the pathological examination of the biopsy specimen showed moderate to poorly(More)
The isotonic, nonionic, contrast medium iodixanol, as a test substance, was compared with the conventional glomerular filtration rate (GFR) tracer inulin to establish a simplified procedure for estimating the GFR in Holstein dairy cows. First, inulin and iodixanol were coadministered as a bolus intravenous injection to clinically healthy cows at 30 mg/kg(More)
