The antidiabetic effect of seeds of Strychnos potatorum Linn. was evaluated in a model of diabetes mellitus using streptozotocin (40 mg/kg b.w., i.p.). Changes in fasting blood sugar were estimated periodically for 12 weeks along with weekly measurement of body weight, food and water intake for 4 weeks. The antidiabetic effects were compared with glipizide as the reference hypoglycemic drug. St...
Background: Preoperative fasting of clear fluids is recommended to reduce the incidence of pulmonary aspiration under anesthesia but non-compliance may cause aspiration or an inconvenient delay in surgery. Safe reduction of fasting time below the current standard of 2 hours has been reported but has not been demonstrated clinically. The aim of this study was to determine if reducing the fast of...
BACKGROUND/AIMS Food residue is frequently observed in the gastric remnant after distal gastrectomy, despite adequate preparation. We devised a water-intake method to reduce food residue in the gastric remnant by drinking large quantities of water in a short time. The aims of this study were to identify the risk factors for food residue and to study the effectiveness of this new method for endo...
This study was undertaken to determine the mechanisms that regulate cholesterol synthesis in vivo and to quantitate the relative importance of the liver and extrahepatic tissues as sites for sterol synthesis. Rats were administered [3H]water intravenously and killed 1 hour later. The amount of [3H]water incorporated into digitonin-precipitable sterols was then measured in liver, whole blood, an...
A method is introduced for estimating the contribution of gluconeogenesis to glucose production. 2H20 is administered orally to achieve 0.5% deuterium enrichment in body water. Enrichments are determined in the hydrogens bound to carbons 2 and 6 of blood glucose and in urinary water. Enrichment at carbon 6 of glucose is assayed in hexamethylenetetramine, formed from formaldehyde produced by per...
The quantity of deuterated glucose customarily given in labelled IVGTTs (intravenous glucose tolerance tests) changes the isotopic composition of the subject's body water enough to be detected by mass spectrometric techniques. Glucose undergoing direct glycogenesis does not contribute label to the body water pool, and isotope incorporated into it must have come from glucose that has either been...
AIM Preoperative fasting is an established procedure to be practiced for patients before surgery, but optimal preoperative fasting time still remains controversial. The aim of this study was to investigate the effect of "shortened preoperative fasting time" on the change in the amount of total body water (TBW) in elective surgical patients. TBW was measured by multi-frequency impedance method. ...
