Whole-Transcriptome Analysis of Repeated Low-Level Sarin-Exposed Rat Hippocampus and Identification of Cerna Networks to Investigate the Mechanism of Sarin-Induced Cognitive Impairment

Biology, 2023
Sarin is a potent organophosphorus nerve agent that causes cognitive dysfunction, but its underlying molecular mechanisms are poorly understood. In this study, a rat model of repeated low-level sarin exposure was established using the subcutaneous ...

The Impairment of Spatial Memory Following Low-Level Sarin Inhalation Exposure and Antidotal Treatment in Rats

Acta Medica, 2002
1. To study the influence of antidotes on low-level sarin-induced impairment of cognitive functions, the rats were exposed to three various low concentrations of sarin (LEVEL 1–3) for 60 minutes in the inhalation chamber.
