Postmenopausal depression is closely associated with depletion of estrogen which modulates transmission of 5-HT, a key neurotransmitter that regulates stress-managing circuits in the brain. In this study, antidepressive efficacy of white ginseng (Panax gingseng Meyer, WG) was evaluated in stressed ovariectomized rats. Female Sprague Dawley rats were ovariectomized and repeatedly restraint stressed for 2 weeks (2h/day). Thirty minutes before restraint stress, rats were administered saline (control), WG 200 mg/kg (p.o.), WG 400 mg/kg (p.o.), or fluoxetine (PC, 10 mg/kg, i.p.). Tail suspension test (TST) and forced swimming test (FST) were performed to assess antidepressant effect of WG. After behavioral tests, levels of serum corticosterone (CORT) and hippocampal 5-HT were measured. Significant decrease of immobility time in TST and FST was shown in rats administered with PC or WG 400 compared to the control. WG200-treated rats showed remarkable reduction in immobility time of TST. PC, WG 200, or WG 400-administred group exhibited significant reduction of CORT compared to the control. PC or WG-treated rats exhibited remarkable increase in hippocampal 5-HT concentration compared to the control. Hippocampal 5-HT levels in WG groups were higher than those in the PC group. The present study demonstrated that WG had antidepressant efficacy in an animal model of menopausal depression. Treatment with WG enhanced hippocampal 5-HT level while suppressing depressive symptom and serum CORT level. These results provide evidence that WG plays an important role in activating serotonergic neurons in stressful situation, suggesting that WG might be a reliable natural alternative of antidepressant drugs to treat menopausal depression.

The mortality of individuals suffering from depression has been increasing, noticeably of postmenopausal women; consequently, their care and treatment are significant to retain a high quality of life. The aim of this study was to examine the effect of Camellia sinensis (CS) on repeated stress-induced changes of the depression related function on the tail suspension test (TST), forced swimming test (FST) in ovariectomized female rats. After behavioral test, we evaluated the changes in the neurotransmitter by measuring the level of dopamine in the nucleus accumbens (NaC) and the serum levels of estrogen and oxytocin. We used 18F-2-fluoro-deoxy-D-glucose positron emission tomography (18F-FDG-PET) to examine the effects of CS on glucose metabolism in ovariectomized rats. Female rats were randomly segregated into three groups. Nor group was considered as nonoperated and nonstressed group, while the control was the ovariectomized and stressed group (OVX+ST), and CS was the ovariectomized, stressed and CS treated group. The rats were exposed to immobilization stress (IMO) for 14 d (2 h/d), and CS (300 mg/kg, i.p.) was treated 30 min before IMO stress. Significant reduction of immobility in the TST and FST was indicated in rats treatment with CS compared to the control group (OVX+ST). The levels of estrogen in the serum of the Nor and CS groups were significantly elevated compared to the OVX+ST group. Also, CS activated brain glucose metabolism in the cortex. The present findings suggested that CS had antidepressant effectiveness in a menopausal depression animal model. These findings suggest evidence that CS plays a crucial role in stressful situation, providing that CS might be a dependable antidepressant medicine to treat menopausal depression.

AbstractObjectivesPrevious studies have suggested antidepressant properties for modafinil; however, the underlying mechanisms mediating the antidepressant effect of modafinil have not been well recognized in clinical and animal studies. Nitric oxide (NO) is involved in the pathophysiology of depression. We attempted to investigate the possible role of NO in the antidepressant-like effect of modafinil in mouse forced swimming test (FST) and tail suspension test (TST).MethodsThe antidepressant-like effect of modafinil (25, 50 and 75 mg/kg), alone and in combination with l-arginine, l-arg, (100 mg/kg) and NG-l-arginine methyl ester, l-NAME (5 mg/kg), was evaluated using FST and TST. Following behavioral tests, the hippocampi were dissected out to measure nitrite levels.ResultsFindings suggested that administration of modafinil at doses of 50 and 75 mg/kg significantly reduced immobility time in the FST and TST. Furthermore, administration of l-arg and l-NAME increased and decreased, respectively, the immobility time in the FST and TST. We showed that co-administration of a sub-effective dose of modafinil (25 mg/kg) plus l-NAME potentiated the antidepressant-like effect of the sub-effective dose of modafinil. In addition, co-treatment of an effective dose of modafinil (75 mg/kg) with l-arg attenuated the antidepressant-like effect of the effective dose of modafinil. We showed that the antidepressant-like effect of modafinil is associated with decreased nitrite levels in the hippocampus.ConclusionsOur findings for the first time support that the modulation of NO, partially at least, is involved in the antidepressant-like effect of modafinil in mouse FST and TST.

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.

Background: In over 300 million clinical cases, antidepressant drugs seem to provide only symptomatic relief and limited protection in life-threatening depressive events. Objective: To compare neuronal-signaling mechanism and neuroprotective roles of Thymoquinone (TQ) suspension and its SLN (TQSLN) against standard antidepressant drug fluoxetine. Results: As compared to fluoxetine, TQ reporteda significantly better docking score (-6.83 v/s -6.22) and a better lower free binding energy of (-34.715 Kcal/mol v/s -28.537 Kcal/mol). While poorly oral bioavailable and P-gp substrate TQ reported approximately 250% higher gut permeation if delivered as TQSLN formulation. In locomotor studies, as compared to TQS, TQSLN favored more prominent (p < 0.010) elevation in average time, horizontal-activity, average-velocity, and total-movement with reduced rest time LPS treated groups. However, in the tail suspension test, TQSLN significantly reduced immobility time (p<0.010). Similarly, In the modified force swimming test, TQSLN also significantly reduced immobility time (p<0.010), but swimming time (p<0.010) and climbing time (p<0.050) were significantly elevated. Conclusion: Despite the poor bioavailability of TQ, TQSLN potentially attenuates neuroinflammatory transmitters and favors BDNF to modulate depressive neurobehavioral states.

The present work was carried out to assess the Onosma bracteatum anxiolytic and antidepressant properties. Swiss albino mice (male) were fed orally with hydroalcoholic extract at different doses 50, 100, and 200 mg 1 hour prior to test with the standard diazepam and fluoxetine. Anxiolytic and antidepressant activities were evaluated by using open field, elevated plus maze, force swimming, and tail suspension test. Results of open field test showed an increase in number of line crossing as well as number of rearing in dosage-dependent design. Although results of elevated plus maze test evidently showed antianxiety effect of O bracteatum by increasing the time spent in open arms along with decreasing the time spent in closed arms in dosage-dependent way. For the evaluation of antidepressant effect, O bracteatum diminished the immobility time and expanded mobility time in forced swim model in dosage-dependent way. Likewise, O bracteatum expanded time span of mobility along with diminished immobility time in tail suspension method in dosage-dependent way. Outcome demonstrated that plant at the dose of 200 mg/kg body weight showed significant potential which was similar to that standard diazepam and fluoxetine. Hence, O bracteatum may be used as potent natural psychotherapeutic agent against the mental disorders.

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).

Abstract Blue light has been previously reported to play a salient role in the treatment of seasonal affective disorder. The present study aimed to investigate whether blue light had antidepressant effect on light-deprivation-induced depression model, and the underlying visual neural mechanism. Blue light mitigated depression-like behaviors induced by light deprivation as measured by elevated sucrose preference and reduced immobility time. Blue light enhanced melanopsin expression and light responses in the retina. We also found the upregulation of serotonin and brain derived neurotrophic factor expression in the c-fos-positive areas of rats treated with blue light compared with those maintained in darkness. The species gap between nocturnal albino (Sprague-Dawley rat) and diurnal pigmented animals (human) might have influenced extrapolating data to humans. Blue light has antidepressant effect on light-deprived Sprague-Dawley rats, which might be related to activating the serotonergic system and neurotrophic activity via the retinoraphe and retinoamygdala pathways. Blue light is the effective component of light therapy for treatment of depression.

To date, the search for novel pharmacotherapy from medicinal plants for psychiatric illnesses has significantly progressed. This study investigated the effect of selected crude extracts from Pilea microphylla in the mouse forced test (FST) and in the tail suspension test (TST), two models predictive of antidepressant activity. Selected crude extracts from Pilea microphylla produced an antidepressant–like effect, since the acute treatment of mice with extracts by intraperitoneal (i.p.) route significantly reduced the immobility time in the FST (50 and 100 mg/kg) and TST (50 and 100 mg/kg), as compared to positive controls (haloperidol and fluoxetine) at 1 and 10 mg/kg, respectively. The antidepressant–like effect of extracts was found to be significant at high doses, followed by an increase in the immobility time at dose of 100 mg/kg. A significant decreased of immobility was also found on the third day at the concentration of 100 mg/kg of chloroform extract of Pilea microphylla from extraction method II (CEPM II) and ethyl acetate extract of Pilea microphyllafrom extraction method II (EAEPM II); (except methanol extract ofPilea microphylla from extraction method I (MEPM I) at 100 mg/kg) with respect to the first day. Ethyl acetate and chloroform extract from extraction method II when administered at an acute dose of 100 mg/kg of body weight (P < 0.05) reduced the immobility time. Among all the three selected extracts with two doses administered there were differences compared to the control, EAEPM II led to reduction of immobility time, in the FST method by 38.50% for 50 mg/kg to as much as 75.97% for 100 mg/kg. Similar results of increased antidepressant effect, that was, of immobility time depending on the concentration administered, were obtained with the TST method. These results suggested the anti–depression activity of the plant extract. Therefore, P. microphylla may be served as a potential resource for natural psychotherapeutic agent against depression. However, further studies are still required.

Tetragonia tetragonioides, which is a halophyte and grows widely in Asian-Pacific regions, has been used for the treatment of digestive disorders in traditional oriental medicine. This study examined the potential antidepressant effect of Tetragonia tetragonioides in an astroglial degeneration model of depression, which was established based on the postmortem study of depressive patients’ brain presenting diminished astrocytes in the prefrontal cortex. C57BL/6 male mice were exposed to glial ablation in the prefrontal cortex by the administration of the gliotoxin, L-alpha-aminoadipic acid (L-AAA) to induce depression. Tetragonia tetragonioides at doses of 100 mg/kg and 300 mg/kg, imipramine at a dose of 15 mg/kg, and distilled water were orally administrated to mice for 18 days. Behavioral tests including the open field test (OFT), sucrose preference test (SPT), forced swimming test (FST), and tail suspension test (TST) were carried out after 2 days of L-AAA injection. The expression levels of GFAP and NeuN in the prefrontal cortex were determined by immunohistochemistry. Mice subjected to glial ablation in the prefrontal cortex displayed decreased sucrose consumption in SPT and increased immobility time in FST and TST. Treatment with imipramine and Tetragonia tetragonioides remarkably ameliorated the behavioral despair induced by L-AAA. In addition, immunohistochemistry analysis showed that treatment with Tetragonia tetragonioides significantly restored the glial loss as indicated by the elevated GFAP expression level. These findings suggest that Tetragonia tetragonioides exerts an antidepressant effect through the restoration of glial loss under conditions of depression and can be a candidate for an antidepressant agent.

SUMMARY Research background. Depression has become a global threat to human health. In order to solve it, researchers have conducted multi-faceted studies including diet. Many food-derived bioactive substances have shown antidepressant effects. However, there are few studies on the design of industrialized food with antidepressant effect. This study aimed to evaluate the antidepressant effect of a functional beverage made from several ingredients with potential antidepressant function and investigate its antidepressant mechanisms. Experimental approach. The beverage consists of peppermint oil, active peptides derived from bovine milk casein and Acanthopanax senticosus extract (ASE) whose active ingredient is eleutheroside. Different amounts of ASE were evaluated to determine the optimal concentration of eleutheroside in this functional beverage to deliver best antidepressant effect through extensive behavioral testing including preliminary acute stress experiments and further chronic unpredictable mild stress test. Results and conclusions. The results demonstrated that the beverage with 15.00 mg/kg of eleutheroside could significantly reduce the mice’s immobility time of tail suspension test and forced swimming test, recover mice’s sucrose preference and behavior changes in the open-field test, improve the contents of dopamine, norepinephrine, 5-hydroxytryptamine and the activity of superoxide dismutase and reduce the content of malondialdehyde in mice’s brains, which indicated that the improvement of monoamine neurotransmitter systems and antioxidation was one potential mechanism of antidepressant action. Novelty and scientific contribution. This study provides a design of antidepressant functional beverage and an efficient way for the prevention and treatment of depression.
