The aim of the present study was to assess metabolic changes occurring in Holstein cows with left or right abomasal displacement. Total sialic acid (TSA) values of the left abomasal displacement (LDA) group were elevated significantly (p < 0.0001) as compared to the controls. In the LDA group, serum ceruloplasmin (CPN) and aspartate transaminase (AST) levels were increased significantly (p < 0....
The delayed upstroke of the arterial pulse in valvular aortic stenosis has been attributed, in part, to prolonged left ventricular emptying. Left ventricular emptying rate, however, has not been measured in aortic stenosis. We assessed the rate of left ventricular emptying by computer analysis of biplane cineangiograms in seven normal subjects, six patients with mild to moderate aortic stenosis...
I. 15NH4C1 was continuously infused for periods of 120-216 h into the rumens of sheep which were allowed to feed 2 out of every 10 min. These treatments achieved steady metabolic states and allowed the assessment of nitrogen conversions by means of tracer methodology. The sheep were given either a barley diet or one of three hay diets. In two trials, the flow of abomasal material was determined...
One of the major microvascular complications of DM includes a 60-70% reduction of gastric mucosal blood flow in diabetic patients which ultimately influences the rate of gastric emptying [2]. It has been reported that 28-65% of diabetic patients experience delayed gastric emptying with an inverse relationship between the rate of gastric emptying and the bloodglucose concentration [2]. It is not...
Symptoms suggesting gastroparesis in patients without gastric outlet obstruction are very common but their relation to an objective delay of gastric emptying has been poorly investigated. A dual isotopic technique was used to evaluate patients with non-obstructive dyspepsia (idiopathic and secondary) (part 1) and to assess the effects of a new gastrokinetic agent: cisapride, on gastric emptying...
The effect of a single dose of (+/-)-fenfluramine hydrochloride (40 mg) on gastric emptying of a mixed solid and liquid meal was assessed with a dual isotope scintigraphic technique in eight obese patients. Fenfluramine significantly delayed gastric emptying of solid food (approximately a 15% reduction in the solid linear emptying rate), but had no effect on gastric emptying of liquid.
Direct as well as indirect evidence suggests that rapid gastric emptying may be occurring in Mexican Americans, American Indians, and other ethnic groups. Mexican Americans have been shown to have a more rapid rate of gastric emptying compared to non-Hispanic Whites after matching for weight, sex, and body mass index. Indirect evidence also suggests that American Indians and other ethnic groups...
To study the dynamics of liquid gastric emptying in rhesus monkeys under conditions that simulated gastric fill during a meal, we measured the gastric emptying of liquid glucose at various concentrations and volumes when administered intragastrically at rates ranging from 12.5 to 37.5 ml/min. Glucose gastric emptying was faster during than following the period of gastric fill. At a single gluco...
A recently developed three-compartment model for the absorption and elimination of ingested alcohol was applied to re-analyse a study on the effects of various factors known to influence the blood-alcohol curve. The absorption and elimination of alcohol after drinking diluted alcohol were studied in healthy volunteers under strictly standardized conditions. The factors studied were sex, dose, c...
BACKGROUND/AIMS The administration of liquid nutrients to patients is often accompanied by complications such as gastroesophageal reflux. To prevent gastroesophageal reflux, high-viscosity liquid meals are used widely, however, it still remains controversial whether high-viscosity liquid meals have any effect on the rate of gastric emptying. The present study was conducted with the aim of deter...
