Abstract
Dementia is a substantial public health concern. Scopolamine (Scop) is a muscarinic acetylcholine receptor antagonist that induces cognitive impairment. The objective of this study was to demonstrate the potential mechanisms by which Baicalein (Baic) might protect against cognitive abnormalities caused by Scop. The thirty male albino rats were divided into three groups: Scop, Scop plus Baic, and control (10/group). After four weeks neurobehavioral assessment was conducted in conjunction with the measurement of hippocampal MDA, SOD, acetylcholine, BDNF, TNF-α, IL-6, IL-1β, and PI3K, Akt, and NF-kB gene expression. The immunohistochemical analysis of Bax, Tau, and GFAP markers was assessed. Scop induced cognitive impairment in rats with a significant increase in the expression of MDA, TNF-α, IL-6, IL-1β, and NF-kB genes, as well as a substantial decrease in the expression of hippocampal SOD, BDNF, acetylcholine, and hippocampal PI3K and Akt genes, as well as an upregulation of GFAP, Tau, and Bax immunoreactions, however Baic dramatically improved Scop-induced cognitive impairment. We can conclude that Baic induced anti-oxidant, anti-inflammatory, neurotrophic, and anti-apoptotic mechanisms in addition to modifying the PI3K/Akt/NF-kB signaling cascade to mitigate the cognitive impairments brought on by Scop.
