Operational Medical Issues in Hypo- and Hyperbaric Conditions

Hyperbaric environment up-regulates CD15s expression on leukocytes, down-regulates CD77 expression on renal cells and up-regulates CD34 expression on pulmonary and cardiac cells in rat

Objective(s): The aim of this study was to estimate effects of hyperbaric (HB) treatment by determination of CD15s and CD11b leukocyte proinflammatory markers expression.  In addition, this study describes changes in CD77 and CD34 expression on rat endothelial cells in renal, pulmonary and cardiac tissue following exposure to hyperbaric pressure. Materials and Methods:Expression of CD11b and CD...

Hyperbaric chamber attendant safety II: 14-year health review of multiplace chamber attendants.

INTRODUCTION The multiplace hyperbaric chamber provides a unique working environment for health-care personnel. The major foci of concern regarding staff health under these conditions have tended to be decompression sickness (DCS) and barotrauma. Incidences of DCS as high as 1.3% have been reported in hyperbaric attendants exposed to routine treatment tables. Occupational health risks of this m...

Study Of Interaction of Glutathione, Vitamin C and Vitamin E Under Hyperbaric Oxygen

In order to study the interaction of glutathione, vitamin C and vitamin E under hyperoxia (95 % oxygen) and hyperbaric oxygen (2.5 atmospheric pressure), 20 days old male Guinea pigs were fed with basal vitamin C free diet, while receiving a vitamin C supplement of either high concentration (50 mg/day) or low concentration (1 mg/day) for two weeks. Animals were than exposed to hyperoxia and hyp...

Treatment of nervous system injuries by hyperbaric oxygen: a review of molecular mechanisms

Background and aims: The use of hyperbaric oxygen therapy is one of the treatment methods to treat many diseases and injuries such as decompression sickness, wound healing, carbon monoxide poisoning, thermal burns, and nervous system injuries. This article aims to review the possible mechanisms of the effectiveness of this treatment in neurological injuries according to the available studies...
