Animal euthanasia It was proposed that the presence of pentobarbital in dog food may have caused dogs to become less responsive to the drug when being euthanized. However, a 2002 FDA study found no dog or cat DNA in the foods they tested, so it was theorized that the drug found in dog food came from euthanized cattle and horses. Furthermore, the level of the drug found in pet food was safe. Animal euthanasia Animal euthanasia (euthanasia from ; "good death") is the act of putting an animal to death or allowing it to die by withholding extreme medical measures. Reasons for
Animal model of ischemic stroke the mechanisms which have been used are: One of the most commonly used animal models of hypoxic ischemia was originally described by Levine in 1960 and later refined by Rice et al., in 1981. This approach is useful to study hypoxic ischemia in the developing brain, since newborn rat pups are utilized in this model. Briefly, 7 day old rat pups undergo a permanent unilateral carotid artery ligation with a subsequent 3 hour exposure to a hypoxic environment (8% oxygen). This model creates a unilateral infarct in the hemisphere ipsilateral to the ligation, since the hypoxia alone is subthreshold for
