Extract of and its kaurene diterpene, xylopic acid, improve learning and memory in mice.

Background: Cognitive dysfunction, presenting as learning and memory impairment, is a common manifestation in many chronic diseases of the nervous system. Some of these diseases include depression, epilepsy, and Alzheimer's disease. To date, few drugs or medicinal products have shown ability to improve learning and memory deficits.

Gestational iron supplementation reverses depressive-like behavior in post-partum Sprague Dawley rats: Evidence from behavioral and neurohistological studies.

Background: Postpartum depression is a mood disorder that affects about 9-20% of women after child birth. Reports suggest that gestational iron deficiency can cause a deficit in behavioral, cognitive and affective functions and can precipitate depressive symptoms in mothers during the postpartum period. The present study examined the effect of iron supplementation on depressive behavior during postpartum period in a rat model.

Antidepressant Potentials of Components from (Thonn.) J.J. de Wilde in Murine Models.

is a common medicinal plant used traditionally in treating central nervous system conditions such as epilepsy, depression, pain, and psychosis. In this study, the antidepressant-like effect of crude extracts of the stem bark of was investigated using two classical murine models, forced swimming test (FST) and tail suspension test (TST). The extracts, petroleum ether, ethyl acetate, and hydroethanolic extracts (30-300 mg/kg, ), standard drug (imipramine; fluoxetine, 3-30 mg/kg, ), and saline (vehicle) were given to mice one hour prior to the acute study.

An extract of Synedrella nodiflora (L) Gaertn exhibits antidepressant properties through monoaminergic mechanisms.

Synedrella nodiflora (SNE) has been used traditionally for many neurological conditions and some of these neuroactive effects have been scientifically substantiated. The usefulness of SNE in depression has however not been investigated despite the availability of data in other disease models indicating it may be useful. The present study therefore examined the effect of SNE in acute murine models of depression and the possible mechanisms mediating its activities in these models.
