Gastric emptying of liquids in rats dehydrated by water deprivation.
The gastric emptying of liquids was investigated in male Wistar rats (8 to 10 weeks old, 210-300 g) dehydrated by water deprivation. In this model of dehydration, weight loss, hematocrit and plasma density were significantly higher in the dehydrated animals than in the control groups after 48 and 72 h of water deprivation (P < 0.05). Three test meals (saline (N = 10), water (N = 10) and a WHO r...
متن کاملAtrial stretch delays gastric emptying of liquids in awake rats.
AIMS We previously reported that mechanical atrial stretch (AS) by balloon distention increased gastric tonus in anesthetized rats. The present study evaluated the effect of AS on the gastric emptying of a liquid test meal in awake rats and its underlying neural mechanisms. MAIN METHODS Anesthetized male rats received a balloon catheter into the right atrium and a gastrostomy cannula. The nex...
متن کاملGastric emptying of water in term pregnancy.
BACKGROUND Healthy nonpregnant patients may ingest clear liquids until 2 h before induction of anesthesia without adversely affecting gastric volume. The purpose of this study was to compare gastric emptying in term, nonlaboring pregnant women after ingestion of 50 ml water (control) with that after ingestion of 300 ml water. METHODS Gastric emptying was assessed in healthy, nonobese, term pr...
متن کاملEffect of bacterial lipopolysaccharide on gastric emptying of liquids in rats.
The objectives of the present investigation were 1) to study the effect of bacterial lipopolysaccharide (LPS) on rat gastric emptying (GE) and 2) to investigate a possible involvement of the vagus nerve in the gastric action of LPS. Endotoxin from E. coli (strain 055:B5) was administered sc, ip or iv to male Wistar rats (220-280 g body weight) at a maximum dose of 50 micrograms/kg animal weight...
متن کاملMethotrexate-induced intestinal mucositis delays gastric emptying and gastrointestinal transit of liquids in awake rats.
CONTEXT Methotrexate and other anticancer agents can induce intestinal mucositis, which is one of the most common limiting factor that prevent further dose escalation of the methotrexate. OBJECTIVES To evaluate the gastric emptying and gastrointestinal transit of liquids in methotrexate-induced intestinal mucositis. METHODS Wistar rats received methotrexate (2.5 mg/kg/day for 3 days, subcut...
