The anatomy and physiology of blood flow to the spinal cord is examined. The role of auto regulation of blood flow within the spinal cord is also examined. This review examines the reported results from the scientific literature of the effect of thoracic aortic aneurysm repair on spinal cord blood flow. In the light of the-se findings several conclusions can reasonably be reached. These conclusions are that the development of SCI can reasonably be predicted based on complexity and extent of the TEVAR procedure performed and BP augmentation and CSF drainage can significantly reduce the impact of SCI.展开更多
In this study, we investigated whether increases in hippocampal blood flow (HBF) by tooth pulp stimulation (TPS) are mediated via the activation of cyclooxygenase-2 (COX-2). We measured mean arterial blood pressure (M...In this study, we investigated whether increases in hippocampal blood flow (HBF) by tooth pulp stimulation (TPS) are mediated via the activation of cyclooxygenase-2 (COX-2). We measured mean arterial blood pressure (MABP) and HBF in urethane-anesthetized rats using laser Doppler flowmetry and examined the effects of etodolac, a specific COX-2 inhibitor, on TPS-induced MABP and HBF responses. The MABP response was not attenuated by the intraperitoneal (i.p.) administration of etodolac (10 mg/kg);however, the HBF response was significantly attenuated by etodolac administration. These results suggest that COX-2 may be involved in the mechanisms regulating TPS-induced HBF responses.展开更多
