Antidepressant-like effect of liquiritin from Glycyrrhiza uralensis in chronic variable stress induced depression model rats

Abstract

Many flavonoids extracted from nature plants have been reported to exert antidepressant-like effect in animal studies. The present study was designed to observe the effects of liquiritin, a flavone compound derived from Glycyrrhiza uralensis, on the behaviors of chronic variable stress induced depression model rats and to explore the possible association between its antidepressant-like effect and antioxidative activity by measuring erythrocyte superoxide dismutase (SOD) activity and plasma malondialdehyde (MDA) level of the experimental animals. With the exposure to stressor once daily for consecutive 5 weeks, liquiritin and a positive control drug fluoxetine were administered via gastric intubation to rats once daily for consecutive 3 weeks from the 3rd week. The results showed that CVS reduced open-field activity and sucrose consumption significantly, but increased immobility time in forced swimming test. Treatment of liquiritin could effectively reverse alteration in immobility time and sucrose consumption but did not show significant effect on open-field activity. Moreover, liquiritin could increase SOD activity, inhibit lipid peroxidation, and lessen production of MDA, while fluoxetine did not. In conclusion, the present study demonstrated a potential antidepressant-like effect of liquiritin treatment on chronic variable stress induced depression model rats, which might be related to defense of liquiritin against oxidative stress.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In rats displaying depressive-like behaviour induced by chronic mild stress, administration of liquiritin decreases immobility time, increases sucrose consumption, increases SOD activity, and attenuates MDA production in the peripheral blood.

    “In rats displaying depressive-like behaviour induced by chronic mild stress, administration of liquiritin, an antioxidant derived from Glycyrrhiza uralensis, decreased immobility time, increased sucrose consumption, increased SOD activity, and attenuated MDA production in the peripheral blood [55].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
