Twenty-four hour gastric acidity after vagotomy.
Twenty-four hour intragastric pH during normal daily activity has been studied by nasogastric intubation and aspiration of gastric samples in seven patients four years after vagotomy (four truncal, three selective). Two of these patients also had pre- and early postoperative studies. Mean pH was inversely correlated with basal, insulin- and pentagastrin-stimulated acid outputs. However, one of ...
متن کاملTwenty-four hour simulation of solar chimneys
A model for time dependent analysis of solar chimneys is presented. The energy balance equations for three components of solar chimneys, absorbing plate, cover glass and air-gap are discretized with respect to time using an implicit finite difference model. The discretized nonlinear energy balance equations are solved for numerous time steps over a 24-h period using the Newton–Raphson method. T...
متن کاملTwenty-four hour efficacy of glaucoma medications.
Current medical therapy of glaucoma aims to attain a meaningful and consistent reduction of intraocular pressure (IOP) to a predetermined level of target IOP, which will commensurate with either stability, or delayed progression of visual loss. Glaucoma is a 24-h disease and the damaging effect of elevated IOP is continuous. Therefore, it is reasonable that we should endeavor to identify the tr...
متن کاملTwenty-four hour presence of physicians in the ICU
Intensive-care units (ICUs) must be utilised in the most efficient way. Greater input of intensivists leads to better outcomes and more efficient use of resources. 'Closed' ICUs operate as functional units with a competent on-site team and their own management under the supervision of a full-time intensivist directly responsible for the treatment. Twenty-four-hour coverage by on-site physicians...
متن کاملTwenty-four-hour beta-endorphin secretory pattern in stroke patients.
BACKGROUND AND PURPOSE Abnormalities of hypothalamo-pituitary-adrenocortical axis function have been observed frequently in stroke patients. The aim of this study was to investigate plasma beta-endorphin and cortisol 24-hour secretory patterns in patients early after stroke and in the convalescent period to evaluate a possible influence of brain damage on hormonal circadian pattern. METHODS P...
