Background: To explore the mechanism of hyperbaric oxygen (HBO) intervention on acute lung injury secondary to snake venom poisoning and provide more toxicological and clinical evidence for venom poisoning.
Methods: Male Kunming mice (n = 96) were randomly divided into four groups: the control group which was not given any interventional treatments, venom group in which each mouse was injected with venom (1 mg/kg) through the tail vein, antivenom group in which each mouse was injected with anti- venom immediately after the model was successfully established, and HBO+antivenom group in which each mouse was given HBO treatment at 1 h, 5 h, 11 h and 23 h following the injection of antivenom. Lung tissues of mice were obtained and processed for the detection of the lung coefficient, the levels of inflammatory factors such as interleukin (IL)-6, IL-10 and IL-17, and the protein expression of retinoic acid receptor (RAR)-related orphan receptor gamma (RORγt) and forkhead box P3 (FOXP3).

Providing pigs with organic enrichment material is important for satisfying pigs' natural explorative behavior to prevent injurious tail biting and thus increase animal welfare in general. The aim of this study was to investigate the effects of automatically supplied enrichment material of three different types (alfalfa pellets, oat bran pellets, or a mixture of both) and different enrichment frequencies (2, 4, or 6 supplies/day) on the behavior, the occurrence of tail biting, and daily weight gains of weaner pigs. The results showed significant effects and interactions of enrichment material, frequency and the time of day on the exploratory behavior, the occurrence of tail biting, and daily weight gains.
