Beneficial Effects of Some Nutraceuticals Containing Glucosamine and Antioxidant against CCL4 Induced Brain Injury in Rats

Abstract

The present study is performed to investigate the effect of two different glucosamine containing drugs: Drug 1 and Drug 2 (D1 and D2) against CCl 4 induced brain damage in male albino rats. Liverin (AM) was employed in the current study as an antioxidant reference drug. CCl 4 administration caused a significant elevation in the levels of MDA and NO of brain tissue, in association with a significant decrease in the antioxidant defense system (GSH, SOD and GPX) that indicated the induction of oxidative stress in brain tissue. CCl 4 administration induced brain injury as manifested by the obtained changes in neurotransmitter parameter (norepinephrine (NE), Dopamine (DA), Serotonin (5-HT), and Acetylcholinesterase AChE). The tested nutraceuticals and the antioxidant drug displayed a significant improvement against the undue effect of CCl 4 via decreasing the brain tissue content of MDA, NO with the elevation of GSH content. Also, the significant increase in SOD and GPX enzymatic activity was obtained when compared to CCL 4 group. In addition AM, D1, and D2 have an ameliorative effect on neurotransmitter parameter NE, DA, 5HT, and AChE. Results of this study suggest that both antioxidant drugs and tested nutraceuticals palliate the brain injuries through anti-oxidative effect, with the elimination of the deleterious effect of toxic metabolites of CCl 4 on brain tissue.
