OBJECTIVE
to assess the effect of systemic hypoxia on gastric mucosa and the activation of stress-responsive transcription factors induced by hypoxia.
METHODS
in this experimental study, rats were allocated to control and experimental groups. The experimental group was divided into subgroups and
In 50 patients with gastric ulcer indices of oxygen tension (pO2) levels were investigated in correlation with the concentration of prostaglandins (E and F2 alpha), prostacyclin, thromboxane as well as with values of transmucous difference of potentials in different parts of the gastric mucosa, they
We studied the relation of hypoxia-inducible factor-1alpha (HIF-1alpha) to vascular endothelial growth factor and vasoactive factors during the healing of gastric ulcers. The gastric ulcers were divided into three stages (active stage, healing stage and scar stage). The expression of HIF-1alpha,
OBJECTIVE
Patients with sleep apnea sustain cessation of breath during sleep, leading to intermittent hypoxia, systemic inflammation, and sympathetic activation. These insults may contribute to initiation or progression of peptic ulcers. This retrospective matched-control cohort study explored the
The incidence of postoperative chest X-ray abnormalities, arterial hypoxemia and clinically recorded pulmonary complications was studied in fifty-two 40-75-year-old men admitted for elective surgery for peptic ulcer or gallbladder disease. Twenty-eight (54%) patients had an abnormal chest X-ray and
Intermittent normobaric hypoxia (13-23 daily sessions 30-50 min each) alleviated the dyspeptic and pain syndromes, improved the objective characteristics of the gastrointestinal tract, and promoted healing of duodenal and peptic ulcers.
The clinical consequences of postoperative complications as defined by signs and symptoms, chest radiography and measurements of the arterial oxygen tension were studied in 53 men, aged 40-75, who were electively operated for peptic ulcer or gallbladder disease. Clinical signs of a respiratory
