The Extraction of DAM Enhance Antioxidant Capacity of Mice In-vivo by Jingxue Wang in Open Access Journal of Biomedical Science
A
mixture of functional complex extraction from Dendrobium Candidum and other
Chinese herbs enhances. Plant polysaccharides are one of the most bioactive
substances present in plants. Due to the broad-spectrum therapeutic properties
and biosafety, natural polysaccharides isolated from plants have recently been
attracted attention by more and more researcher. The present study was designed
to investigate the possible anti-aging and intestinal flora effect of
Dendrobium Candidum and Astragalus mongholicus (DAM) on the aging model mouse.
In the experiment, 48 aging female Institute of Cancer Research mice (ICR mice)
were randomly divided into the control group and low-mediumhigh dose groups
(200,400,800 mg/kg/day). The results showed that gradually recovered the body
weight, the activity of daily living, and organ indices of mice. To be
specific, DAM obviously improved the activities of antioxidant enzymes in liver
and spleen of ICR mice, including catalase (CAT) and superoxide dismutase
(SOD), as well as decreased malondialdehyde (MDA) levels when compared with
those in control group mice. Furthermore, the DAM can improve the
weight-bearing swimming time of the mice, increase the tolerance of the aging
body, shorten the mouse’s adaptation to the labyrinth, increase the number of
individuals entering the open end and prolong their stay time on the basis of
not affecting the mobility of the mice and has a certain anti-anxiety effects.
The abundance of pathogenic bacteria of Bilophila and Oceanobacillus in the intestinal
tract of aging mice was higher than that of the compound compound intragaemia
group. The abundance of intestinal probiotics such as Akkermansia, Bacteroides
and Bifidobacterium in the low-dose group was higher than that of the aging
control group, and also higher than that of the medium-dose and high-dose
groups. These results demonstrate that DAM preparation had an effect on
improving the antioxidant capacity of organs in aging mice, delaying the aging
of organs, and enhancing the resistance of aging individuals.
