Extracts from wool dyed with sawwort (Serratula tinctoria L.) obtained with methanol/formic acid and methanol/hydrochloric acid solutions were examined by high-performance liquid chromatography with UV detection coupled with electrospray ionization tandem mass spectrometry. Chromatograms and mass spectra were registered in the negative ion mode under various orifice voltages and collision energ...

ion Ezchunye Resins-De-Acidite (The Permutit Company, New York), washed on a 40 mesh screen with distilled water, was treated several times with aqueous 4 per cent sodium carbonate and repeatedly washed with distilled water, by suspension and decantation, until the supernatant liquid was colorless and had a pH of 8.0 or less. The resin collected on a suction filter contained 70 to 80 per cent w...

The aim of this study was to evaluate by atomic force microscopy (AFM) the early phases and evolution of dental enamel erosion caused by hydrochloric acid exposure, simulating gastroesophageal reflux episodes. Polished bovine enamel slabs (4x4x2 mm) were selected and exposed to 0.1 mL of 0.01 M hydrochloric acid (pH=2) at 37 ?#61472;?#61616;C using five different exposure intervals (n=1): no ac...

I)I)ISONIAN pernicious anemnia is ami expressiomi of the deficiemicy of vitan imi B12 which results from lack of secretion of Castle’s imit.rimisic factor iii the stomach. It has been kuioivn to be associated with atrophy of the gastric mucosa for about 80 yearst and with gastric achlorhydria for 70 years.2 The latter has been so constant. a fimiding that it has almost always been regarded as e...

OBJECTIVE(S) Gastroesophageal Reflux Disease (GERD) is one of the most common digestive disorders that frequently lead to pulmonary complications due to gastric fluid aspiration. In the present experimental study, chronic aspiration of gastric fluid, its components and bile salts in rat lung was performed to find out the main factor(s) causing pulmonary complications of gastric fluid aspiration...

From 8 to 15 mM of strong mineral acid per kilogram of body weight may be infused intravenously in the dog over a period of a few hours to produce a severe but non-fatal acidosis. Van Slyke and Cullen (1) showed that only one-sixth of the infused acid is neutralized by blood buffers, five-sixths presumably being neutralized by bicarbonate in interstitial fluid and lymph and by intracellular pho...

or microscopic in the wall of stomach and bowel. No abnormality of the digestive juices in the small intestine has been recorded. In the stomach, however, there would appear to be some interference with normal function. Marriott' found in cases of coeliac disease that there was a marked deficiency of free hydrochloric acid in the gastric juice and that this gradually returned to normal limits a...
