BACKGROUND Hydrochloric acid aspiration increases pulmonary microvascular permeability. The authors tested the hypothesis that partial liquid ventilation has a beneficial effect on filtration coefficients in acute acid-induced lung injury. METHODS Isolated blood-perfused rabbit lungs were assigned randomly to one of four groups. Group 1 (n = 6) served as a control group without edema. In grou...

In a previous article (1)) on the secretion of gastric juice in fever, it was reported that the concentration of’ chlorides in gastric juice was constant or slightly reduced. In this present paper I wish to emphasize the relation between the secretion of total chlorides in gastric juice and the secretion of free hydrochloric acid. Most of the data for this paper were obtained at that time but u...

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...

introduction conventional water treatment consist of unit processes include coagulation, flocculation, clarification, filtration and disinfection that goal is removal of turbidity, color and certain bacterial species. in filtration process flocculated substances that have not removed in pervious stage are sediment. filter media is often silica sand that removal mechanism is complex and consists...
