Immunomodulatory and Antioxidant Activity of Gouqi Chewable Tablets
To explore the regulatory effect of Gouqi chewable tablets on innate and adaptive immunity in normal mice and its antioxidant activity
in vitro
and
in vivo
.
Method
2
The effects of low-, medium-, and high-dose groups (0.25, 0.5, 1.5 g·kg
-1
) on the immune function of normal mice were observed by carbon clearance test, immune organ index test, serum hemolysin test, ConA-induced splenic lymphocyte proliferation test, and natural killer cell (NK cell) activity test. The effects of Gouqi chewable tablets on the antioxidant capacity
in vivo
were determined by detecting the content of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and malondialdehyde (MDA) in mice serum. The
in vitro
antioxidant activity of Gouqi chewable tablets was detected by 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH), and hydroxyl radical scavenging tests.
Result
2
Compared with the blank control group, the low-, medium-, and high-dose groups of Gouqi chewable tablets improved the viability of NK cells, the proliferation of splenic lymphocytes, and the level of serum hemolysin antibody in mice (
P
<
0.05). The high-dose group increased the thymus index, spleen index, and phagocytic function of macrophages (
P
<
0.05,
P
<
0.01). As compared with the blank control group, the activity of GSH-Px in mice serum in the medium-dose group was increased (
P
<
0.05), and the content of MDA in mice serum in the high-dose group was decreased (
P
<
0.05). In
in vitro
antioxidant tests, the median inhibitory concentration (IC
50
) values of Gouqi chewable tablets were 1.64±0.20, 2.04±0.03, and 10.27±0.03 g·L
-1
by the DPPH, ABTS, and OH
-
free radical method, respectively. Those results indicated that Gouqi chewable tablets have good antioxidant effects
in vitro
.
Conclusion
2
Gouqi chewable tablets can enhance the immune function of mice with good antioxidant effects.
