Abstract
Metabolic and mood-related disturbances can increase the risks of developing adverse mental health problems. The medicinal mushroom, Ganoderma lucidum, is utilized in indigenous medicine to improve quality of life, promote health, and boost vitality. This study investigated the effects of Ganoderma lucidum ethanol extract (EEGL) on feeding behavioral parameters, depressive-like symptoms, and motor activity in Swiss mice. We hypothesized that EEGL would have beneficial effect on metabolic and behavioral outcomes in a dose-related manner. The mushroom was identified and authenticated via techniques of molecular biology. Forty Swiss mice (n = 10/group) of either sex were given distilled water (10 mL/kg) and graded doses of EEGL (100, 200, and 400 mg/kg) orally for 30 days, during which feed and water intake, body weight, neurobehavioral, and safety data were documented. The animals experienced a significant decrease in body weight gain and feed intake while water intake increased in a dose-dependent manner. Furthermore, EEGL significantly diminished immobility time in forced swim test (FST) and tail suspension test (TST). At the 100 and 200 mg/kg, EEGL did not cause significant alteration in motor activity in the open field test (OFT). Meanwhile, an increase in motor activity in male mice without remarkable difference in female mice was observed at the highest dose (400 mg/kg). Eighty percent of mice treated with 400 mg/kg survived till day 30. These findings suggest that EEGL at 100 and 200 mg/kg reduces the amount of weight gained and elicits antidepressant-like effects. Thus, EEGL might be useful for the management of obesity and depressive-like symptoms.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Carpolobia lutea decoction is widely used as a phytotherapeutic against central nervous system-related disorders including insomnia, migraine headache, and mental illness in West and Central Tropical Africa. AIM This study was designed to investigate the antipsychotic activity of Carpolobia lutea (EECL) in mice models of psychosis. METHODS Male Swiss mice (n = 5/group) were given EECL (100, 200, 400, and 800 mg/kg), haloperidol (1 mg/kg), clozapine (5 mg/kg) and vehicle (10 mL/kg) orally before amphetamine (5 mg/kg)-induced hyperlocomotion and stereotypy, apomorphine (2 mg/kg)-induced stereotypy, or ketamine (10, 30, and 100 mg/kg)-induced hyperlocomotion, enhancement of immobility and cognitive impairment. RESULTS EECL (200, 400, and 800 mg/kg) prevented amphetamine- and apomorphine-induced stereotypies, as well as reduced hyperlocomotion induced by amphetamine and ketamine, all of which are predictors of positive symptoms. Regardless of the dose administered, EECL prevented the index of negative symptoms induced by ketamine. Furthermore, higher doses of EECL (400 and 800 mg/kg) also prevented ketamine-induced cognitive impairment, a behavioral phenotype of cognitive symptoms. CONCLUSION Pretreatment with EECL demonstrated antipsychotic activity in mice, preventing amphetamine-, apomorphine-, and ketamine-induced schizophrenia-like symptoms, with 800 mg/kg being the most effective dose.

Abstract
Oxidative and inflammatory signaling pathways have been identified as important targets for mitigating hypoxic stress-induced neurological complications. Thus, the effects of naringenin, a potent antioxidant, anti-inflammatory and neuroprotective bioflavonoid on hypoxic stress-induced depressive-like and anxiety-related behaviors in mice, and the underlying molecular mechanisms were evaluated in this study. Thirty-five male Swiss mice were distributed into 5 groups (n = 7). Mice in group I (non-stress control) and group 2 (stress-control) both had vehicle (5 % DMSO), while groups 3-5 received naringenin (10, 25 and 50 mg/kg), intraperitonally. Thirty minutes later, mice in groups 2-5 were subjected to 15 min hypoxic stress, daily for 14 days. Locomotor activity, anxiety and depression were evaluated on day 15. The mice brains were processed for malondialdehyde, glutathione, superoxide-dismutase (SOD), catalase, tumor necrosis factor-alpha (TNF-α) and interleukin-1β assays. The serum corticosterone concentration and expressions of the brain immunopositive cells of inducible nitric oxide synthase (iNOS), nuclear factor kappa-B (NF-kB) and brain derived neurotrophic factor (BDNF) as well as histomorphological changes of the amygdala were also determined. Naringenin (25-50 mg/kg) ameliorated the hypolocomotion, depressive- and anxiety-like behaviors in hypoxic mice. The increased brain contents of malondialdehyde, TNF-α, interleukin-1β, and decreased antioxidant (glutathione and SOD) status were attenuated by naringenin. Naringenin (10 mg/kg) increases BDNF expression but did not significantly (p < 0.05) alter corticosterone and catalase contents. The increased expressions of iNOS and NF-kB as well as loss of amygdala neuronal cells were reduced by naringenin (10 mg/kg). Overall, these findings suggest that naringenin improves depressive- and anxiety-like behaviors in mice exposed to hypoxic stress by modulating oxido-inflammatory insults and NF-kB/BDNF expressions.

Abstract
Blighia unijugata (Sapindaceae) is an indigenous tree belonging to the tropical forests of West Africa. It is called "Ako Isin" by the Yoruba people of Southern-Western part of Nigeria, where it is among plants used traditionally in the management of depressive psychosis. The aim of this present study was to evaluate the anti-depressant activity of ethanol extract of Blighia unijugata leaves in-vivo using acute and chronic experimental models of depression. The antidepressant activity of ethanol extract of B. unijugata leaves was investigated using acute and chronic unpredictable mild stress. Depression tests used included forced swimming, tail suspension, yohimbine induced lethality and reserpine induced depression tests. Oxidative stress markers were also assessed in the brain homogenates after chronic unpredictable mild stress. The acute toxicity studied using oral route of administration was 1414 mg/kg. The results showed that, B. unijugata produced significant reduction in immobility time in forced swimming and tail suspension tests without stimulating in locomotor activity in open field test. It was also found that B. unijugata significantly reversed diarrhea, ptosis and hypothermia in reserpine model of depression. 2.5 mg/kg B. unijugata potentiated yohimbine induced lethality in mice and also reduced the oxidative stress markers. The ethanol extract of B. unijugata leaves possessed antidepressant action, thus justifying its use in the management of mental illness.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Moringa oleifera (family Moringaceae), commonly called Horseradish or tree of life, is traditionally used for the treatment of epilepsy and neurologic conditions. AIM OF THE STUDY The objective of this study is to investigate the neurobehavioural and anticonvulsant properties of the ethanol extract from the leaves of Moringa oleifera. MATERIALS AND METHODS Neurobehavioural properties were evaluated using the open field, hole board, Y-maze, elevated plus maze (EPM) and pentobarbitone-induced hypnosis. Pentylenetetrazole (leptazol), picrotoxin and strychnine induced convulsion tests were used to investigate the anti-convulsive actions of Moringa oleifera. RESULTS The result showed that the extract (250-2000mg/kg) caused a significant dose-dependent decrease in rearing, grooming, head dips and locomotion (P<0.001). It also enhanced learning and memory and increased anxiogenic effect. In addition, the extract (2000mg/kg) protected mice against pentylenetetrazol induced convulsion, but has no effect on picrotoxin and strychnine induced convulsion. The effects of the extract in the various models were comparable to those of the standard drugs used except in Y-maze, EPM and picrotoxin and strychnine induced convulsion. The LD50 obtained for the acute toxicity studied using oral route of administration was >6.4g/kg. CONCLUSION The findings from this study suggest that the ethanol extract of Moringa oleifera leaves possesses CNS depressant and anticonvulsant activities possibly mediated through the enhancement of central inhibitory mechanism involving release γ-amino butyric acid (GABA). The results partially justified the traditional use of the extract for the treatment of epilepsy.
