The effect of hypophysectomy and bovine growth hormone (GH) administration on somatostatin (SRIF) content as well as gastrin content in the rat stomach was investigated. SRIF content was determined by a specific radioimmunoassay. The total SRIF content in the stomach had decreased 4 weeks after hypophysectomy but was restored significantly in those rats which were subjected to bovine GH adminis...

The effect upon the lower oesophageal sphincter (LOS) of acid in the proximal stomach was investigated in 12 young healthy subjects. The cardia was perfused in turn with solutions at pH 7, 4, 3, 2, and 1, during successive withdrawals of three perfused pressure-recording catheters, openings of which were at the same axial level. Although there was considerable individual variation, there was a ...

Vagotomy in the rat initially caused a significant reduction in acid secretion of the stomach after operation, with complete recovery noted 4 weeks later. Histamine content in the gastric wall also revealed a similar reduction and recovery after vagotomy. The increase in acid secretion responding to tetragastrin was observed as well to diminish markedly and then recover, over a similar course o...

We found that concentrations of nitrogen (N) in the stomach of voles varied between forest sites. Concentrations of nitrogen as well as the ratio of nitrogen to carbon (C) in stomach content were not different between the sexes or with season. Body mass varied between sites and between seasons but were unrelated to N concentration in spite that the body mass of voles in the spring season were o...

Diet of adult pikeperch Sander lucioperca, Eurasian perch Perca fluviatilis, northern pike Esox lucius and European catfish Silurus glanis as top predators in aquatic ecosystems in Serbia was investigated during 2011, in order to understand their relationship to their prey and to investigate their food consumption, feeding and assimilation rate, cannibalism, and habitat segregation. Northern pi...

Martin, M.D., F.R.S. Pp. xvi., 505. Edinburgh: Young J. Pentland. 1895. So many years have elapsed since an authoritative treatise on diseases of the stomach has appeared from British sources,, and so much advance has been made in recent years in our knowledge of the pathology of disorders of the stomach, that this book will be perused with great interest. The gain in knowledge of gastric affec...

Pulmonary aspiration of gastric contents is one of the most feared complications of anaesthesia. Prevention of aspiration by identification of patients at risk, preoperative fasting, drug treatment and various anaesthetic manoeuvres are cornerstones of safe anaesthetic practice. Not surprisingly, the number of articles and case reports regarding the pulmonary consequences of gastric aspiration ...
