Transvaginal sonosalpingography, with its accuracy and safety, is a promising screening and diagnostic technique in the evaluation of tubal patency on ambulatory basis.

SummaryThe susceptibility of red blood cells to hydrogen peroxideinduced lipid peroxidation was determined for 30 pregnant women in the second stage of labor before and after hyperbaric oxygen therapy. Thirty non-pregnant women were chosen and studied as healthy controls.The results obtained before and after hyperbaric oxygen therapy were compared, and the oxygen therapy was found to cause a significant increase in erythrocyte susceptibility to lipid peroxidation (p <0.001), an increased plasma lipid peroxide value (p <0.001), and a significant decrease in glutathione level (p <0.001). Osmotic fragility curves showed that oxygen therapy caused the appearance of a population of slightly fragile cells, as evidenced by tailing.Reactive oxygen radical formation, their toxic effects in causing lipid peroxidation, and the possible measures that can be taken in such a case are discussed.
