Acute pancreatitis (AP) is a complex disease that may be linked to acinar cell apoptosis and inadequate acinar cell replacement. Differentiation of acinar cells is regulated by p48, a DNA binding subunit of the transcription factor PTF1, and the Notch signaling pathway. Acinar cell apoptosis is
Respiratory Function has been measured in 14 patients with acute pancreatitis, none of whom has a previous history of cardiac or respiratory disease. Their mean age was 40 years, mean PaO2 on admission, 11 kPa, and all had normal chest radiographs at that time. Arterial hypoxia was a common
The purpose of the present study was to investigate the prognostic role of severe hypoxemia on admission as an independent risk factor of pulmonary complications and mortality in patients with acute pancreatitis. Pulmonary complications were studied in 166 previously healthy patients with acute
Severe arterial hypoxia while breathing ambient air (Pao2 less than 60 mm Hg) was recorded in 38 (45 per cent) of a group of 84 patients with acute pancreatitis when arterial blood gas monitoring was performed during the first week of illness. This contrasted with an incidence of 19 per cent severe
OBJECTIVE
To observe the therapeutic effect of hyperbaric oxygen (HBO) on acute pancreatitis (AP) by downregulating hypoxia-inducible factor (HIF).
METHODS
Forty Wistar rats were randomly divided into 4 groups (n = 10): sham group, AP group, normo-oxygen group (NP) and HBO group. At 4 hours after
Emerging data have provided evidence for the presence of a local renin-angiotensin system (RAS) in the pancreas, which play a role in the regulation of pancreatic microcirculation, thus affecting islet hormonal secretion. The present study aimed, therefore, at elucidating the presence and changes of
The circulating renin-angiotensin system (RAS) plays an important role in the maintenance of blood pressure and fluid homeostasis. Recently, there has been a shift of emphasis from the circulating RAS to the local RAS in the regulation of individual tissue functions via a paracrine and/or autocrine
Purpose: Acute pancreatitis (AP) is an inflammatory disorder distinguished by tissue injury and inflammation of the pancreas. Using paracrine potential of mesenchymal stem cells (MSCs) provides a useful clinical approach in treating inflammatory diseases. We investigated the therapeutic
The aim of this study was to investigate the effects of hypoxia-inducible factor-1α (HIF-1α) and matrix metalloproteinase-9 (MMP-9) on alveolar-capillary barrier disruption and lung edema in rat models of severe acute pancreatitis-associated lung injury (PALI). A total of 40 male Sprague-Dawley rats
The present study was conducted to investigate the effect and potential mechanism of hypoxia-inducible factor-1α (HIF-1α) genetic inhibition plus glutamine (Gln) supplementation on necrosis-apoptosis imbalance during acute pancreatitis (AP), with a specific focus on the regulations of
OBJECTIVE
This study investigated the role of hypoxia-inducible factor 1alpha (HIF-1alpha) in acute pancreatitis (AP) and whether HIF-1alpha is involved in the therapeutic effects of hyperbaric oxygen (HBO) on AP.
METHODS
Thirty Wistar rats with taurocholate-induced AP were randomly assigned to 3
