Repeated Atmospheric Pressure Alteration Effect on the Cochlea in Rats: Experimental Animal Study.

This study aimed to evaluate the effects of repeated pressure alterations on cochlear structures in rats in an attempt to understand indirectly the inner ear status of flight crew who are repeatedly exposed to pressure alterations. There were 12 adult Wistar albino rats equally divided into 2 groups: Group 1 (controls) and Group 2 (study group). The animals in Group 2 were exposed to repeated pressure changes in a pressure cabin which is regulated by manometers.

The effect of hyperbaric oxygen therapy on fracture healing in nicotinized rats.

Background: The aim of the present study was to investigate the effect of hyperbaric oxygen therapy on fracture healing in nicotinized rats.

Methods: Thirty-two rats were divided as follows: nicotinized group (1), hyperbaric oxygen group (2), nicotinized + hyperbaric oxygen group (3), and control group (4). For 28 days, nicotine was administered in Groups 1 and 3.

The effect of hyperbaric oxygen treatment on the healing of burn wounds in nicotinized and nonnicotinized rats.

The importance of oxygen in wound healing and the negative effects of cigarette smoking have been demonstrated in various studies. In this study, our aim was to investigate the effect of hyperbaric oxygen (HBO2) treatment on wound healing in nicotinized and nonnicotinized rats. The study was conducted on 32 Sprague Dawley rats.

The effect of hyperbaric oxygen therapy on the survival of random pattern skin flaps in nicotine-treated rats.

Previous studies have shown that nicotine increases the risk of necrosis in skin flaps. We investigated the effect of hyperbaric oxygen (HBO(2)) treatment on the survival of random skin flaps in nicotine-treated rats. Thirty-two Sprague-Dawley rats were divided into four groups with eight rats in each group.

Can hyperbaric oxygenation decrease doxorubicin hepatotoxicity and improve regeneration in the injured liver?

Background/purpose: Portal vein embolization is used in the treatment of hepatocellular cancer, with the purpose of enhancing resectability. However, regeneration is restricted due to hepatocellular injury following chemotherapeutics (e.g.

Dysbaric osteonecrosis in experienced dive masters and instructors.

Introduction: Dysbaric osteonecrosis (DON) is a type of aseptic bone necrosis of long bones such as the humerus, femur, and tibia. It is observed in workers who perform in high-pressure environments.

Methods: There were 58 volunteer divers included in this study who had performed at least 500 dives, were working as a dive master or instructor, had never performed industrial and commercial dives, and did not have a diagnosis of osteonecrosis.
