Effects of tempol, a membrane-permeable radical scavenger, on local and remote organ injuries caused by intestinal ischemia/reperfusion in rats.

Background: Tempol is a stable piperidine nitroxide of low molecular weight that permeates biological membranes and scavenges superoxide anions in vitro. In a variety of animal models, deleterious effects of reperfusion injury on both local and remote organs have been demonstrated. In this study, we aimed to investigate the effects of a membrane-permeable radical scavenger, Tempol, on local and remote organ injuries caused by intestinal ischemia/reperfusion (I/R) in rats.

Activated protein C prevents deleterious effects of remote reperfusion injury caused by intestinal ischemia on wound healing in the left colonic anastomoses: an experimental study in the murine model.

Background: Activated protein C (APC) is a serine protease with anticoagulant and antiinflammatory activities. The delaying effects of remote reperfusion injury on the wound-healing process in colonic anastomoses have been previously shown. In this study, we aimed to investigate whether APC protects against deleterious systemic effects of intestinal ischemia/reperfusion (I/R) injury on colonic anastomotic wound healing process.

Activated protein C attenuates intestinal reperfusion-induced acute lung injury: an experimental study in a rat model.

Background: Activated protein C (APC) is a serine protease with anticoagulant and anti-inflammatory activities. APC has been shown to attenuate local deleterious effects of ischemia/reperfusion (I/R) injury in many organs. We aimed to investigate the effects of APC on lung reperfusion injury induced by superior mesenteric occlusion.

Role of allopurinol on oxidative stress in caustic burn: cure for stricture?

An experimental study was conducted to investigate the effects of allopurinol, which inhibits the enzyme xanthine oxidase, on oxidative stress and on the prevention of stricture development after esophageal caustic injuries in rat. A randomized controlled study was conducted and 60 Wistar albino rats were divided into 6 equal groups, three groups for the acute phase and 3 groups for the chronic phase. Caustic esophageal burn was created by application of 37.

Analysis of zinc and magnesium levels in pinealectomized chicks: roles on development of spinal deformity?

Melatonin is the main product of the pineal gland, and trace metals play a critical role in growth and development. The purpose of this study was to assess the serum zinc (Zn) and magnesium (Mg) levels in pinealectomized chicks and their possible interactions with the development of spinal deformity. Chicks were divided into two equal groups: unoperated controls (group M) and pinealectomized chicks (group N).

Correlation of serum trace elements and melatonin levels to radiological, biochemical, and histological assessment of degeneration in patients with intervertebral disc herniation.

The aim of our study was to assess the blood concentrations of some trace elements and melatonin (MLT) in patients with intervertebral disc herniation (IDH) and to investigate the interaction of histological and biochemical degeneration findings with aging. The present study was carried out on 13 subjects (8 women and 5 men) diagnosed with IDH. They were divided into three groups according to their ages.
