Hyperbaric oxygen stimulates vasculogenic stem cell growth and differentiation in vivo

Hyperbaric oxygen stimulates vasculogenic stem cell growth and differentiation in vivo

We hypothesized that oxidative stress from hyperbaric oxygen (HBO2, 2.8 ATA for 90 min daily) exerts a trophic effect on vasculogenic stem cells.

The efficacy of hyperbaric oxygen (HBO2) for healing refractory wounds in diabetic patients and those with radiation injuries has been shown in randomized trials, and its utilization is supported by independent evidence-based reviews (6, 10, 20, 32, 38). Mechanisms of action for HBO2 are not clear. The goal of this study was to examine the impact of HBO2 on vasculogenic stem cells in an in vivo animal model.

Expanded adipose-derived stem cells for the treatment of complex perianal fistula including Crohn’s disease

Expanded adipose-derived stem cells for the treatment of complex perianal fistula including Crohn’s disease

In patients without Crohn’s disease, surgery is the mainstay treatment but faecal incontinence and recurrence are high. Infliximab is used in Crohn’s patients but not all respond to therapy. Objective: After an evaluation of the current treatment options, we discuss studies of adipose-derived stem cell (ASC) therapy, a novel approach for treating complex perianal fistulas.

Methods: ASCs are obtained from a liposuction procedure and a subsequent expansion process. They are administered according to a strict protocol which involves infusion of the cells into the target lesion along with fibrin glue.

Exposure to increased pressure or hyperbaric oxygen suppresses interferon-gamma secretion in whole blood cultures of healthy humans.

Exposure to increased pressure or hyperbaric oxygen suppresses interferon-gamma secretion in whole blood cultures of healthy humans.

This study examines the effects of hyperoxia, increased atmospheric pressure, and hyperbaric oxygen on cytokine synthesis.

Five healthy volunteers were exposed to 90 min of room air, 100% oxygen, 10.5% oxygen at 2 atm abs, or 100% oxygen at 2 atm abs (HBO2). All subjects were blinded and randomly exposed to each of the 4 conditions.

Immediately before entering the chamber, immediately after exposure, and 3 and 24 h later, blood was drawn and stimulated ex vivo with phorbol myristate acetate (PMA) and phytohemagglutinin A (PHA).

The Role of Chemokines and Chemokine Receptors in Mucosal Inflammation

The Role of Chemokines and Chemokine Receptors in Mucosal Inflammation

Recent studies have suggested that nitric oxide (NO.), the product of nitric oxide synthase in inflammatory cells, may play a part in tissue injury and inflammation through its oxidative metabolism

In this study the colonic generation of oxides of nitrogen (NOx) and nitric oxide synthase activity was determined in ulcerative colitis and Crohn’s disease. Colonic biopsy specimens were obtained from inflammatory bowel disease patients and from normal controls. Mucosal explants were cultured in vitro for 24 hours and NOx generation was determined. Nitric oxide synthase activity was monitored by the conversion of [3H]-L-arginine to citrulline. Median NOx generation by inflamed colonic mucosa of patients with active ulcerative colitis and Crohn’s colitis was 4.2- and 8.1-fold respectively higher than that by normal human colonic mucosa.
