Changes of Nuclear Factor Kappa-B Pathway Activity in Hippocampus After Acute Carbon Monoxide Poisoning and Its Role in Nerve Cell Injury.

Abstract

Acute carbon monoxide poisoning (ACOP) causes tissue hypoxia and damage mainly by binding to hemoglobin (Hb). This article aimed to explore the changes in the activity of nuclear factor kappa-B (NF-κB) pathway in the hippocampus after ACOP and its role in nerve cell damage. This article used 30 Sprague-Dawley (SD) rats as the research object, which were randomly divided into two groups, ACOP group and controls. The model of carbon monoxide (CO) poisoning was established, and then the activity of NF-κB pathway in the hippocampus of the two groups of rats was detected, and the statistical analysis was performed. Compared with the controls, the activity of NF-κB pathway in the hippocampus of the ACOP group was significantly increased (P < 0.05). The degree of neuronal damage in the ACOP group was also significantly increased. ACOP increases the activity of the NF-κB pathway in the hippocampus and may cause neuronal damage through this pathway. This provides new ideas and methods for the treatment of ACOP, and also provides new evidence for the role of NF-κB pathway in neuronal injury.
