“…However, in our studies the application of hyperbaria of 1 atm for 30 minutes demonstrated a clear decrease in the a.a.a. Our previous studies [7] demonstrated that hyperbaric oxygenation produced a similar reduction even when the swimming time is significantly shorter.…”

“…The study was conducted on 70 hooded rats, uniform males with the weight of 180-220 g. The animals were kept continuously in a temperature of approximately 24°C and fed ad libitum with a standard diet and water. Animals used in the study were subjected to hyperbaric conditions while at rest or being exposed to exhaustive physical exercise (swimming test) [7,13,14]. The tests were carried out in an experimental pressure chamber for animals, which was filled with air with the pressure raised to 1-3 atn.…”

“…Badania przeprowadzono na 70 szczurach kapturowych, jednorodnych samcach o ciężarze 180-220 g. Zwierzęta przebywały stale w temperaturze około 24°C, otrzymywały standardową dietę hodowlaną i wodę ad libitum. Do badań użyto zwierząt przebywających w hiperbarii w warunkach spokoju lub też poddanych wyczerpującemu wysiłkowi fizycznemu (test pływania) [7,13,14]. Badania przeprowadzano w doświadczalnej komorze ciśnieniowej dla zwierząt, którą napełniano powietrzem i podnoszono ciśnienie do 1-3 atn.…”

“…Natomiast w naszych badaniach zastosowanie hiperbarii rzędu 1 atn przez czas 30 minut dawało już wyraźny spadek n.k.a. W przeprowadzonych przez nas poprzednio badaniach [7] wykazano, że hiperbaria tlenowa ma wpływ na obniżenie podobne nawet przy czasie pływania znacznie krótszym.…”

Numerous research works indicate that staying in a hyperbaric environment is a stressor. We have undertaken studies using an animal model to determine the effect of hyperbaria on adrenocortical secretion and the level of adrenal ascorbic acid (a.a.a.). The research was conducted on 70 male hooded rats, which were divided into groups and subjected to hyperbaric air and oxygen at an overpressure of 1 and 3 atn, with some of the animals being additionally burdened with physical effort (swimming). It was found that short-term exposures (30 minutes) of rats to hyperbaric conditions caused a decrease in the content of a.a.a. With a prolonged (3-hour) exposure to 3 atm air the a.a.a. content returns to a normal level. A reduction in the a.a.a. content indicates the presence of stress in hyperbaric conditions in the rat, however, it does not allow to determine its intensity with the method used in the study.

“…The problems regarding the effects of hyperbaric oxygenation and oxygen toxicity on experimental animals and humans, as well as on the course of the immunological reactions in these conditions, have already been the subject of our interest [13,4,5,8,10] and now prompt us to aim at determination of oxygen toxicity based on the opsonic index. In contrast to a number of publications on the changes in the phagocytic index as an expression of systemic reactivity to toxic agents [9,11], no data have been found in the available literature on the use of the opsonic index in the determination of the effects of hyperbaric oxygenation on the body.…”

Hyperbaric oxygen toxicity studies were conducted on rabbits using the opsonic index determination.The study was conducted on 15 animals that had opsonin index examined prior to hyperbaric oxygen exposure. They were then subjected to an hourly exposure to hyperbaric oxygen with overpressure values of 1.8, 2.4 and 3.1 atm in groups of 5 animals. After the exposure, the opsonium index was re-examined upon the lapse of 1, 2 and 10 days. Parallelly, the morphological image of the blood was examined.There was a statistically significant increase in the index in the first two days after exposure, independent of the value of oxygen overpressure. On the 10th day, the index value approached the initial one.
