conclusions oxygen therapy in the case group had no significant impact on protection from dgf. results forty living kidney transplantations including 17 cases and 23 controls were performed; female gender was more prevalent in recipients (n = 16, 40%). the mean age of recipients was 36.1 ± 12.4 (18-67) years old. dgf was detected in 2 (5.95%) individuals, from whom one was in the case group and...

Reactive oxygen species (ROS)plays an important role in sperm motility. The physiological generation at low concentration induces beneficial effects on sperm functions and plays a significant role in sperm metabolism. Meanwhile, the excessive generation of reactive oxygen species can overwhelm protective mechanism and triggers changes in lipid and protein layers of sperm plasma membrane, which ...

The number of people travelling to the high altitude regions, especially South America, Nepal, and India, has risen enormously in the past 10 years. Without special climbing ability these trekkers can be exposed to altitudes they will not have encountered in their home countries. For example, the height of Everest base camp is 5500 m whereas the top of Mount Blanc, the highest mountain in the A...

144,000 hits on Google for the two words “bleomycin” and “scuba” demonstrate the continued interest in the subject of diving after bleomycin therapy; some very conservative, and some more liberal regarding recommendations. My thanks to UHM, which published “Scuba diving post-bleomycin therapy” (UHM 2010, Vol. 37, No. 6, p. 455), documenting a recreational diver’s return to scuba after his chemo...

Recompression using oxygen is the accepted treatment for decompression injury. As early as 1877 Paul Bert stated that recompression using oxygen is the optimal treatment for decompression problems (2). He also pointed out that this treatment was very effective for getting rid of the gas from the vascular system but much less effective against paralysis and the serious types of decompression sic...

Oxygen is widely available and commonly prescribed by medical and paramedical staff. When administered correctly it may be life saving, but oxygen is often given without careful evaluation of its potential benefits and side effects. Like any drug there are clear indications for treatment with oxygen and appropriate methods of delivery. Inappropriate dose and failure to monitor treatment can hav...
