Polygonatum humile Fisch is commonly called Sookjuk in Korea. The roots of P. humile are typically used in traditional medicine as an anti-rheumatic, demulcent, and sedative agent. The aim of this study was to evaluate the potential of the P. humile extracts to treat depression. Mice were administered P. humile water extract (PH) and were subjected to the forced swim test (FST), tail suspension test (TST), and open-field test (OFT). The levels of brain monoamines including serotonin (5-HT), norepinephrine, and dopamine were evaluated. In addition, the PH antidepressant-like effects were studied based on the regulation of 5-HT-mediated Ca2+ and extracellular signal-regulated kinase 1/2 (ERK1/2) in human 1321N1 cells stably expressing the 5-HT subunit 6 receptor (5-HT6). In FST and TST, PH (300 mg/kg) significantly reduced the immobility time without changing the locomotor activity in mice. In addition, PH enhanced the level of 5-HT in the mice brain. The results further indicated an inhibitory activity of PH on both   the 5-HT6 receptor expression level and the 5-HT6 receptor dependent downstream signal   pathway ERK1/2.These findings indicated antidepressant-like effects of PH  as evidenced by decreased immobility time in mice through a 5-HT6 receptor antagonistic mechanism.

Background: An imbalance between pro-oxidants and antioxidants determines the level of oxidative stress which is implicated in the etiopathogenesis of various neuropsychiatric disorders including depression. Therefore, treatment with antioxidants could potentially improve the balance between pro-oxidants and antioxidants. Objective: The objective of this study was to evaluate the ability of astaxanthin, a potential antioxidant, to reduce reserpine-induced depression in BALB/c mice (Mus musculus). Methods: On the behavioral level, antidepressant property of astaxanthin (50 mg/kg, orally) on reserpine (2 mg/kg, subcutaneously) induced depressed mice was evaluated by Forced Swim Test (FST) and Tail Suspension Test (TST). In the biochemical level, the ability of astaxanthin to mitigate reserpine-induced oxidative stress was evaluated by the measurement of Malondialdehyde (MDA) and nitric oxide (NO) in brain, liver and plasma samples. On the other hand, the efficiency of astaxanthin to replenish glutathione depletion and antioxidant enzyme activity augmentation in the same samples were also investigated. Results: Astaxanthin was able to lower reserpine induced immobility time significantly (p<0.05) in FST and TST. Mice treated with astaxanthin showed significantly (p<0.05) low level of oxidative stress markers such as Malondialdehyde (MDA), Nitric Oxide (NO). Consistently, the level of reduced Glutathione (GSH), and the activity of Superoxide Dismutase (SOD) and catalase were augmented due to the oral administration of astaxanthin. Conclusion: This study suggests that astaxanthin reduces reserpine-induced oxidative stress and therefore might be effective in treating oxidative stress associated depression.

Abstract Clinical observations recognized the co-existence and interactions of pain and depression a long time, ago. The aim of this work was to study the effect of ibuprofen and fluoxetine on BCGinduced depressive-like behaviour, on formalin-induced pain, as well as on mechanical allodynia after planter incision in mice. BCG induced a depressive behaviour that was seen in the forced swim test (FST) and the tail suspension test (TST). It also induced a decrease in pain-related behaviour in the formalin test, and an increase in the baseline in mechanical allodynia test compared to the control group. Fluoxetine (80 mg/L of drinking water) showed a significant decrease in the immobility time in the FST and TST and enhanced pain related behaviour in formalin test in the BCG-inoculated group. However, it did not affect the increase in the pain threshold in the planter incision allodynia model. Adding ibuprofen to drinking water (0.2 g/L of drinking water), reversed the depressive like behaviour induced by BCG and enhanced pain-related behaviour in formalin test, in both the total pain-related behaviour and phase 2. It also prevented the increase in the base line induced by BCG. On the other hand, the incisional pain model was not affected by BCG inoculation except at the 2-hour time point, where it showed hypoalgesia, as well.

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.

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:: HeMI (12.5–100 mg/kg, p.o.) was administered 1 h before subjecting the animal to the forced swim test (FST), tail suspension test (TST) and elevated plus maze tests (EPM).: HeMI (12.5–100 mg/kg, p.o.) treatment produced significant reduction in immobility time [F(6.56)=8.35, p<0.001], [F(6,56)=7.55, p<0.001] in the FST and TST, respectively. Moreover, co-administration of sub-therapeutic doses of imipramine or fluoxetine with HeMI (3.125 mg/kg) elicited significant reduction in time spent immobile in the FST. However, pretreatment of mice with parachlorophenylalanine, metergoline, yohimbine or sulpiride abolished the antidepressant-like effect elicited by HeMI. In the EPM, HeMI produced significant [F(5,42)=8.91, p<0.001] increase in open arms exploration by 75.55 % and this effect was blocked by pretreatment of mice with flumazenil or metergoline.: Findings from this study showed antidepressant-like effect of

Baihe Dihuang Tang (BDT) is a renowned Chinese herbal formula which is commonly used for treating patients with mental instability, absentmindedness, insomnia, deficient dysphoria, and other psychological diseases. These major symptoms closely associated with the depressive disorders. BDT was widely popular use for treating emotion-thought disorders for many years in China. In the present study, the antidepressant-like effect of BDT in mice was investigated by using the forced swim test (FST) and the tail suspension test (TST). The underlying mechanism was explored by determining the effect of BDT on the level of cerebral monoamine neurotransmitters. BDT (9 and 18 g/kg, p.o. for 14 days) administration significantly reduced the immobility time in both the FST and the TST without changing locomotion in the open field-test (OFT). Moreover, BDT treatment at the dose of 18 g/kg inhibited reserpine-induced ptosis. Meanwhile, BDT enhanced 5-HT and NA levels in mouse cerebrum as well as decreased the ratio of 5-HT compared to its metabolite, 5-HIAA, (turnover, 5-HIAA/5-HT) after TST. The results demonstrated that the antidepressant-like effect of BDT is mediated, at least partially, via the central monoaminergic neurotransmitter system.

Abstract The present study aims to evaluate the involvement of N-methyl-d-aspartate receptor and nitric oxide (NO)/cyclic guanosine monophosphate (cGMP) system in antidepressant-like effects of Yueju pill (YJ), a Chinese herbal medicine. The immobility time in tail suspension test (TST) and forced swim test (FST) was used to assess the antidepressant effects. Prior administration of L-arginine (750 mg/kg, intraperitoneal [i.p.]), a NO synthase substrate that enhances NO signaling or sildenafil (5 mg/kg, i.p.), a phosphodiesterase 5 inhibitor that enhances cGMP, blunted the antidepressant-like activity of YJ (2.7 g/kg, i.g.). Co-treatment of ineffective dose of YJ (1.35 g/kg, i.g.) with one of the reagents that suppress the NO/cGMP signaling, including methylene blue (10 mg/kg, i.p.), an inhibitor of NO synthase; 7-NI (7-nitroinidazole, 30 mg/kg, i.p.), an nNOS specific inhibitor; L-NAME (10 mg/kg, i.p.), a non-specific inhibitor of NO synthase; and MK-801 (0.05 mg/kg, i.p.), an NMDA receptor antagonist, reduced the immobility time in TST and FST, compared with those in vehicle or single drug treatment groups. Neither above drugs alone or co-administrated with YJ affected locomotor activity or anxiety behavior in open field test. Thus, our results suggest that the antidepressant-like action of YJ may depend on the inhibition of NMDA/NO/cGMP pathway.

Depression, a mental disorder marked by sadness, anhedonia and increased fatigability, is becoming more common in this industry 4.0 era. Nowadays, depression affects approximately 322 million people around the world (more than 14 million in Indonesia) and gives major contribution to the rise of global burden of disease. Although antidepressant is considered the common treatment for depression, recent studies show a possibility to treat depression by altering gut microbiome of the patient, by giving them probiotic food. Tempeh is a globally well-known Indonesian paraprobiotic food which already proven to modulate gut microbiota. This research aimed to find out the effect of tempeh to depression symptom as expressed in Balb/c mice behaviors. The methods used was to feed tempeh or tempeh starter to mice which were depressed-induced by Unpredictable Chronic Mild Stress (UCMS) procedure. Parameter measured were depression level of the Balb/c mice based on immobility times and grooming durations acquired from tail suspension test, forced swim test, sucrose splash test and coat state score. The result showed that tempeh supplementation did not affect coat states and grooming durations but tend to improve immobility times of the Balb/c mice. Meanwhile, tempeh starter supplementation tends to improve the immobility time and kept coat state clean/tidy, but lowered grooming duration. In conclusion, supplementation of paraprobiotic tempeh, especially in starter form, tend to improve depression symptoms. Keywords: depression, mice, paraprobiotic, tempeh

The aim of this analysis was to assess antidepressant & nootropic capacity of Bougainvillea Glabra aqueous extract (BGAE). Forced swim test, tail suspension test, & tetrabenazine mediated catalepsy & ptosis models were used to assess BGAE's antidepressant efficacy in mice at doses of 250 & 500 mg/kg orally. Morris water maze with elevated plus maze (EPM) was used to test nootropic behaviour. Normal medications for antidepressant & nootropic function were imipramine (25 mg/kg) & piracetam (300 mg/kg), respectively. Antioxidant assays such as DPPH & TBARS were used to validate antidepressant & nootropic function. When comparison to car, pre-treatment with BGAE resulted in substantial dose-dependent decrease in immobility time in both FST & TST. (P0.005) Tetrabenazine-induced catalepsy & ptosis were both decreased dramatically. Furthermore, in MWM & EPM, BGAE demonstrated dose-dependent cognitive enhancing behaviour. In DPPH assay, BGAE had IC50 of 17.39 g/ ml, & in TBARS assay, it had IC50 of 398.71 gm/ ml. BGAE has antidepressant & nootropic activities that are equivalent to imipramine & piracetam at doses of 250 & 500 mg/kg, respectively, which may be due to its effect on neurotransmitters & antioxidant function.

The aim of the present work was to evaluate the anti-oxidant and anti-depressant potentials of the Ethanolic bark extract of Annona muricata. Ethanolic bark extracts of Annona muricata was subjected to preliminary and quantitative phytochemical screening. In vitro Anti-oxidant activity of Annona muricata was performed using phosphomolybdenum assay with Ascorbic acid as the standard. As the extract exhibited potent anti-oxidant activity, it was investigated further for its anti-depressant activity using Forced swim test(FST), Tail suspension test(TST), Digital photoactometer test (DPT) and Open field test(OFT). Imipramine & Fluoxetine [10mg/kg] were used as reference drugs for the anti-depressant experiments. Ethanolic Bark extract of Annona muricata exhibited significant anti-oxidant activity with significant increase of absorbance in a concentration dependent manner while in anti-depressant activity there was considerable decrease in the immobility time . Altogether, these results suggest that the Ethanolic bark extract of Annona muricata could be used as a potential anti-oxidant and anti-depressant agent.
