AbstractBackgroundAlbizia zygia (DC.) J.F. Macbr. (Leguminosae) has been used to treat mental disorders in traditional African medicine. Nonetheless, there is limited scientific evidence to justify its present use. The aim of this study was to evaluate the antidepressant activity of the hydroethanolic extract of A. zygia roots (AZE) in murine models.MethodsAZE was evaluated in the tail suspension test, forced swim test, and the repeated open-space swim test of depression. In order to elucidate the mechanisms of action, the activity of AZE was re-evaluated after treating mice with selective inhibitors of monoamine biosynthesis. The potential of AZE to influence spontaneous locomotion was also examined.ResultsAZE (100–1000 mg/kg, p.o.) reduced the immobility time of mice in the tail suspension and forced swim tests (at least p < 0.05). In the repeated open-space swim test, AZE reduced the immobility time (at least p < 0.05) while concomitantly increasing the distance swam by mice (p < 0.01). However, the antidepressant-like activity of AZE was attenuated by α-methyl-para-tyrosine and reserpine (p < 0.0001) but not para-chlorophenylalanine.ConclusionsThe results of this study indicate that AZE possesses antidepressant-like properties and support the traditional use of AZE for the treatment of depression.

Background: The aim of the study was to evaluate the antidepressant effect of opioid analgesic tramadol using forced swim test and tail suspension test models.Methods: The antidepressant effect was assessed by recording the immobility time in Forced swim test (FST) and Tail suspension test (TST). The mice were randomly divided into five groups. Mice belonging to group I was given normal saline (0.1ml/kg) which acted as control. Group II received imipramine (15mg/kg) considered as the standard drug tramadol was given in graded dose (10, 20 and 40 mg/kg) to mice of groups III, IV, V respectively. All drugs were administered intraperitoneally for seven successive days; test was done on 7th day.Results: Tramadol and Imipramine showed antidepressant activity when compared to control. There is dose dependent increase in antidepressant activity of tramadol. The antidepressant activity of imipramine was significantly (P<0.05) more than tramadol at dose 10 and 20 mg/kg but antidepressant activity with tramadol 40mg/kg was comparable to imipramine treated mice.Conclusions: The results of this study indicated the presence of antidepressant activity of tramadol at 40mg/kg.

Depression is a state of excessive sensitivity to criticism, fear of rejections, lack of self-interest, loss of pleasure. In the traditional systems of medicine, many plants and formulations have been used to treat depression for thousands of years. In recent times, research on the plants increased globally and so many plants provide the evidence to cure diseases. Ocimum sanctum, popularly known as Tulsi is one of the sacred herbs for Hindus in the Indian subcontinent. It has a versatile role in traditional medicine. The fruits of Piper nigrum are used to make black pepper. This hotly pungent spice is one of the earliest known and most widely used spices in the world today. Wide range of animal tests for antidepressant agents are commonly used. The Forced swim test and Tail suspension test in mice were mostly used. Hence in the present study Forced swim test was used as animal model of depression. In present study immobility time in Forced swim test was significantly decreased by a combination of Piper nigrum fruit extract and Ocimum sanctum extract treated groups compared to control group. The combination of extracts (50 mg/kg each) activity was comparable to standard drug Fluoxetine. Treatment with extracts does not modify the locomotor activity of mice, which indicates that they exert antidepressant effects without modifying significantly locomotor activity. Therefore, the present study confirms the combination of alcoholic extract of Piper nigrum (AEPN) fruit and aqueous extract of Ocimum sanctum (AEOS) possessing additive/synergistic antidepressant activity.

Objectives: This research was designed to investigate the antidepressant activity of a few structurally related flavones (flavone, 3‑hydroxyflavone, and 7‑hydroxyflavone) and the possible mechanisms involved. Methods: Antidepressant activity was evaluated in mice by subjecting them to forced swim test and tail suspension test. The involvement of adrenergic, serotonergic, nitric oxide (NO), and opioid mechanisms was investigated using suitable interacting chemicals. Results: Flavone, 3‑hydroxyflavone, and 7‑hydroxyflavone exhibited a significant and dose‑dependent reduction in total time of immobility in the forced swim test and tail suspension test. Pre‑treatment with alpha‑methyl‑para‑tyrosine and parachlorophenyl alanine attenuated the reduction in immobility period produced by flavone and its derivatives in forced swim test. Naloxone pre‑treatment partially reversed the effect of flavone while L‑arginine pre‑treatment did not alter their effect. Conclusion: The investigated flavones exhibited promising antidepressant activity in both the animal models of depression. However, the flavone compounds did not alter the motor coordination and ambulatory behavior in the Rotarod and locomotor activity test. The participation of serotonergic, adrenergic, and opioid mechanism in the antidepressant activity of these compounds was elucidated from the results, and the role of NO pathway was excluded.

Background: In recent years, the search for novel pharmacotherapy from medicinal plants for psychiatric illness was significantly progressed. The present study was performed to evaluate the antidepressant activity of ethanolic extract of Lagenaria siceraria in animal models.Methods: The antidepressant activity of ethanolic extract of the fruit of L. siceraria in rats was assessed using forced swim test and tail suspension test. Imipramine at 15 mg/kg was used as standard antidepressant drug.Results: The ethanolic extract of L. siceraria fruit (EELS) was significantly and dose-dependently reduced the duration of immobility after repeated treatment for 7 days in Forced swim test and Tail suspension Test. But combination of L. siceraria (200mg/kg) with Imipramine gave a highly significant result (p<0.001) in reduction of immobility duration and the effect of high dose (400mg/kg) with imipramine (15mg/kg) did not decrease the duration of immobility period in both animal models at end of the study. In this work the dose of 400mg/kg afforded more protection than the imipramine.Conclusions: The results obtained from this study was indicate that the antidepressant activity of L. siseraria.

ObjectiveThe aims of this study were to replicate previously published experiments and to modify the protocol to detect the effects of chronic antidepressant treatment in mice.MethodsMale Swiss mice (n=6–8/group) housed in reversed light/dark cycle were randomly assigned into receive vehicle (10% sucrose), sub-effective doses (1 and 3 mg/kg) or effective doses (10 and 30 mg/kg) of bupropion, desipramine, and fluoxetine and a candidate antidepressant, sodium butyrate (1–30 mg/kg) per gavage (p.o.) 1 h before the forced swim test (FST). Treatments continued daily for 7 and 14 days during retests 1 and 2, respectively. In an additional experiment, mice received fluoxetine (20 mg/kg) or vehicle (10% sucrose or 0.9% saline) p.o. or i.p. before the FST. Mice housed in reversed or standard light/dark cycles received fluoxetine (20 mg/kg) prior FST. Video recordings of behavioural testing were used for blind assessment of the outcomes.ResultsAccording to the expected, doses of antidepressants considered sub-effective failed to affect the immobility time of mice in the FST. Surprisingly, acute and chronic treatment with the high doses of bupropion, desipramine, and fluoxetine or sodium butyrate also failed to reduce the immobility time of mice in the FST. Fluoxetine 20 mg/kg was also ineffective in the FST when injected i.p. or in mice housed in normal light/dark cycle.ConclusionData suggest the lack of efficacy of orally administered bupropion, desipramine, fluoxetine in the FST in Swiss mice. High variability, due to high and low immobility mice, may explain the limited effects of the treatments.

Antidepressant Action

Depression is highly prevalent, increases suicide risk, and is now the leading cause of disability worldwide. Our ability to treat depression is hampered by the lack of understanding of its biological underpinnings and of the mode of action of effective treatments. We hypothesised that the scaffolding proteins in the medial frontal cortex play a major role in effective antidepressant action. We implanted cannulae into the infralimbic cortex to inject chABC and locally remove perineuronal nets and then tested for antidepressant effects with the forced swim test. We further tested if systemic injections of ketamine had an additive effect. Our preliminary data indicate that neither the removal of these scaffolding proteins nor ketamine were sufficient to decrease depression-like behaviour, but may interact synergistically to decrease immobility time in the forced swim test.
