Hyperbaric oxygen therapy reduces COX-2 expression in a dimethylhydrazine-induced rat model of colorectal carcinogenesis.

Background: A better understanding of oncogenesis mechanisms should result in more effective approaches to colorectal cancer (CRC) treatment and prevention. Hyperbaric oxygen (HBO2) therapy is indicated as adjuvant treatment for infectious diseases as well as hypoxic and inflammatory lesions. The anti-inflammatory effect of HBO2 could reduce colorectal carcinogenesis.

Effect of hyperbaric oxygen therapy on the intestinal ischemia reperfusion injury.

Purpose: Adequate tissue oxygenation is essential for healing. Hyperbaric oxygen therapy (HBOT) has potential clinical applications to treat ischemic pathologies, however the exact nature of any protective effects are unclear at present. We therefore investigated the potential role of HBOT in modulating the ischemia/reperfusion (I/R) injury response in intestinal model of I/R injury.
