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.

ABSTRACTPrevention and treatment with synthetic antidepressants has many side effects that affect the central nervous system and usage must be under the supervision of a doctor. Whereas prevention and traditional medicine relatively do not cause side effects, are inexpensive, and easy to obtain. One example of traditional medicine from natural ingredients, which can provide an antidepressant effect is ginger rhizome. This research aims to determine whether ginger rhizome have antidepressant effects on male white mice. Antidepressant effect testing was carried out on male white mice (Mus musculus) using the forced swim test method. The part of the plant used is the rhizome of the ginger plant. Curcuma rhizome is made with juice and given orally with a concentration of 20%, 40%, and 60%. The negative control used is Na CMC 0.5%, while the positive control used, namely amitriptilyn. The parameters observed were the duration of immobility time, swimming time and climibing time (in seconds) which were calculated from minutes 3-6 for 6 minutes, and statistical tests were carried out with a confidence level of 95%. The results showed that at a concentration of 40% the curcuma rhizome juice had a significant value (p> 0.05) which means that there was no significant difference in antidepressant effect (%) from the juice of temulawak 56.31% and amitriptylin 78.78%Keywords: ginger rhizome, antidepressants, the forced swim test

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.

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.

The present study was designed to evaluate the acute and chronic antidepressant effect of genistein in combination with amitriptyline in mice. Animals were divided into six groups (n=6) for treatment with water, genistein, or amitriptyline, either alone or in combination for ten days. Animals were subjected to locomotor activity testing; tail suspension test (TST); and forced swim test (FST) and immobility time was recorded on day one and day ten. Acute treatment of all treatment groups did not significantly reduce the immobility time (p>0.05). Chronic treatment of combination of genistein (10 mg/kg) and amitriptyline (5 mg/kg and 10 mg/kg) significantly reduced the immobility time as compared to control group (p<0.001) and was comparable to amitriptyline alone (10 mg/kg). However, no changes in anti-immobility activity in combination of subeffective doses of genistein (5 mg/kg) and amitriptyline (5 mg/kg) were observed. Genistein at its standard dose (10 mg/kg) rendered synergistic effects in combination with subeffective dose of amitriptyline (5 mg/kg) and additive effects in combination with therapeutic dose of amitriptyline (10 mg/kg).

SMe1EC2M3 is a pyridoindole derivative related to the neuroleptic drug carbidine. Based on the structural similarities of SMe1EC2M3 and known serotonin (5-HT), norepinephrine, and dopamine reuptake inhibitors, we hypothesized that this compound may also have triple reuptake inhibition efficacy and an antidepressant-like effect. PreADMET and Dragon software was used for in silico prediction of pharmacokinetics and pharmacodynamics of SMe1EC2M3. Forced swim test was used to evaluate its antidepressant-like effects. Extracellular in vivo electrophysiology was used to assess 5-HT, norepinephrine, and dopamine reuptake inhibition efficacy of SMe1EC2M3. PreADMET predicted reasonable intestinal absorption, plasma protein binding, and blood-brain permeability for SMe1EC2M3. Dragon forecasted its efficiency as an antidepressant. Using behavioral measurements, it was found that SMe1EC2M3 decreased immobility time and increase swimming time during the forced swim test (FST). Electrophysiological investigations showed that SMe1EC2M3 dose-dependently suppressed the excitability of 5-HT neurons of the dorsal raphe nucleus (DRN), norepinephrine neurons of the locus coeruleus (LC), and dopamine neurons of the ventral tegmental area (VTA). The SMe1EC2M3-induced suppression of 5-HT, norepinephrine, and dopamine neurons was reversed by the antagonists of serotonin-1A (5-HT1A; WAY100135), α-2 adrenergic (α2, yohimbine), and dopamine-2 receptors (D2, haloperidol), respectively. We conclude that SMe1EC2M3 is prospective triple 5-HT, norepinephrine, and dopamine reuptake inhibitor with antidepressant-like properties, however future studies should be performed to complete the pharmacological profiling of this compound.
