We investigated the diet and foraging of the endemic teiid lizard Cnemidophorus littoralis in a restinga habitat in Jurubatiba, Macaé - RJ. The stomach contents were removed, analyzed and identified to the Order level. There was no relationship between C. littoralis morphological variables and number, length or volume of preys. Termites (48.7%) and larvae (35.5%) were the most important prey it...

In much of our experimental work upon mammals, the dosage of the various drugs used is regulated according to the size of the animal-a given amount being allowed per kilo of body-weight. In the rabbit this is a source of considerable error on account of the large size of the stomach and cecum. After a full feeding, when these organs have become well filled, the weight of their contents bears a ...

We studied the rates at which solid and liquid leave the stomach after meals of wholemeal and white bread by using a double isotope technique. There was no difference in the rates at which the solid phases of the gastric contents left the stomach but liquid left the stomach significantly more rapidly with white bread than with wholemeal bread. Furthermore, the amount of liquid leaving the stoma...

The normal mechanism of preventing the reflux of gastric contents into the oesophagus has been studied intensely, but no hypothesis is so easy to prove and understand that it has obtained universal acceptance (Allison, 1956; Barrett, 1954; Botha, Astley, and Carre, 1957; Marchand, 1955). Methods of prevention of reflux which has resulted in oesophageal pathology are therefore variable. Reflux i...

The aim of the study was to investigate the effect of FOLFOX4 regimen combined with Brucea javanica emulsion on the content of serum vascular endothelial growth factor (VEGF) in patients with gastric cancer, and to evaluate the efficacy of FOLFOX4 regimen combined with Brucea javanica emulsion on gastric cancer. A total of 60 patients with gastric ulcer were selected as the normal group, and an...

Editor’s key points † The authors review the literature regarding the use of ultrasound to estimate gastric volume and, thus, aspiration risk. † Suggestions for clinical usage are provided. Pulmonary aspiration of gastric content is a serious anaesthetic complication that can lead to significant morbidity and mortality. Aspiration risk assessment is usually based on fasting times. However, fast...

Peptic ulcer is a common disorder of the stomach and duodenum. Herbs and medicinal plants are considered to be a potential source to combat various diseases including gastric ulcer. The present study was conducted to evaluate the gastro protective effects of Echinacea extract, Green tea extract and Boswellia extract on a pyloric ligation-induced gastric ulcer. Six groups of rats were intraperit...

Since gastric carcinoma, unlike uninvaded mucosa, has a relatively high glycogen content and the risk of gastric carcinoma is especially high in patients with a partially resected stomach, the aim of this study was to follow glycogen storage in both uninvaded gastric stump mucosa and carcinoma developing in the stump postsurgery performed for benign and malignant conditions. One hundred patient...

BACKGROUND Determination of seabird diet usually relies on the analysis of stomach-content remains obtained through stomach flushing; this technique is both invasive and logistically difficult. We evaluate the usefulness of DNA-based faecal analysis in a dietary study on chick-rearing macaroni penguins (Eudyptes chrysolophus) at Heard Island. Conventional stomach-content data was also collected...

Introduction It is generally accepted that fasting reduces the risk of regurgitation and aspiration of gastric contents during induction of anaesthesia and surgery. Children, like adults, are required to fast before general anaesthesia to reduce volume and acidity of their stomach contents [1]. Fasting while waiting for surgery can be a stressful event for the children and their parents. To be ...
