This study investigated the antidepressant activity of ethanolic extract ofU. lanosaWallich var.appendiculataRidsd (ULEtOH) for two-weeks administrations by using FST and TST on mice. In order to understand the probable mechanism of antidepressant-like activity of ULEtOHin FST and TST, the researchers measured the levels of monoamines and monoamine oxidase activities in mice brain, and combined the antidepressant drugs (fluoxetine, imipramine, maprotiline, clorgyline, bupropion and ketanserin). Lastly, the researchers analyzed the content of RHY in the ULEtOH. The results showed that ULEtOHexhibited antidepressant-like activity in FST and TST in mice. ULEtOHincreased the levels of 5-HT and 5-HIAA in cortex, striatum, hippocampus, and hypothalamus, the levels of NE and MHPG in cortex and hippocampus, the level of NE in striatum, and the level of DOPAC in striatum. Two-week injection of IMI, CLO, FLU and KET enhanced the antidepressant-like activity of ULEtOH. ULEtOHinhibited the activity of MAO-A. The amount of RHY in ULEtOHwas 17.12 mg/g extract. Our findings support the view that ULEtOHexerts antidepressant-like activity. The antidepressant-like mechanism of ULEtOHmay be related to the increase in monoamines levels in the hippocampus, cortex, striatum, and hypothalamus of mice.

Background: Cissus quadrangularis has been used for cure of various ailments that includes bone cracks, frail bones (osteoporosis), scurvy, malignant growth, annoyed stomach, hemorrhoids, peptic ulcer sickness, excruciating menstrual periods, asthma, jungle fever (malaria), and mental distress. Specially it is used for bone healing properties. According to this background, the aim of the study was to evaluate the antidepressant-like effect of the ethanolic extract of Cissus quadrangularis (EECQ) in different behavioral models such as forced swimming test (FST) and tail suspension test (TST) on mice after two weeks treatment. Methods: Mice were divided into six groups (n=6/group): control group (normal saline), stress control (normal saline), standard group where Imipramine (15mg/kg) was used as standard drug and three test groups where three doses of ethanolic extract of C. quadrangularis (EECQ) (100, 250, and 350mg/kg) was used for two weeks treatment. All the medication and test samples were managed by means of gavage through oral course. To evaluate the antidepressant like impact of EECQ forced swim test (FST) and tail suspension test (TST) have been done in mice. Results: The outcomes demonstrated that a solid and dose-dependent antidepressant effects in various mice models. The main findings of the EECQ significantly decreased the duration of immobility times in the forced swimming test (p<0.5). Likewise, the extract significantly decreased the immobility time in the tail suspension test (p<0.5) when compared against stress control as well as against imipramine which was used as a standard. Conclusion: The present results clearly demonstrate that the ethanolic extract of C. quadrangularis possesses antidepressant-like activity in the animal behavioral models. Cissus quadrangularis plant can be used for the treatment of neurological disorders and may be recommended as a supplement for the antidepressant activity.

<p>Tail suspension test (TST) is a common behavioral paradigm used to evaluate the antidepressant activity of experimental drugs. Like the forced swimming test, in this test the animals are set in an inescapable yet modestly distressing circumstance. In the tail suspension test, the extent of immobility is thought to be associated with the depressive-like condition of the animal and is significantly diminished by antidepressant drugs.</p><p><strong>Video clips</strong></p><p><a href="https://youtube.com/v/OqWrALPAGhA">Pre-experiment</a>:         53 sec</p><p><a href="https://youtube.com/v/T7sRbrn3xbQ">Experiment</a>:      7 min 31 sec</p><p> </p>

Objective: Depression is a major psychiatric disorder affecting nearly 350 million people worldwide and imposes a substantial health burden on the society. Ceftriaxone has demonstrated neuroprotective effects in animals. It has also undergone trials as a treatment option for amyotrophic lateral sclerosis. This study was therefore undertaken to evaluate the antidepressant-like effect of ceftriaxone in mice.Methods: Ceftriaxone was administered at three different doses (0.130, 0.195 and 0.260g/kg) to Swiss albino mice of either sex by intra peritoneal (i. p.) route. The period of immobility in control and drug-treated mice were recorded in forced swimming test (FST) and tail suspension test (TST). The antidepressant effect of ceftriaxone indicated by the decrease in duration of immobility was compared to that of fluoxetine (0.020 g/kg, i. p.).Results: Ceftriaxone decreased the duration of immobility in mice. It showed a significant dose-dependent antidepressant effect. The antidepressant effect of 0.260g/kg of ceftriaxone was comparable to that of fluoxetine in the TST but not in the FST.Conclusion: The results of the present study indicate antidepressant activity of Ceftriaxone. The study shows that ceftriaxone has additional action on the central nervous system other than neuroprotection. Ceftriaxone therapy in cases of encephalomeningitis and in various cases of hemorrhages in the brain can, therefore, prevent the development of depression in future

Objective: Bisphosphonates are used for treating osteoporosis. Few studies have reported their effect on alterations in comorbid behaviour such as depression. Therefore, present study was performed to investigate the effects of bisphosphonate drugs on depression in adult male Wister rats and Swiss albino mice.Methods: The study was conducted on adult male Wister rats and Swiss albino mice, 36 of each type, equally divided into six groups. One group was classified as control group and the rest were treated as test groups. Initial photoperiod of 12 h was provided for acclimatization, prior to the start of the experiment. Drug administration was not performed in control group. Forced swimming test and tail suspension test were performed to investigate the antidepressant activity. Locomotor activity was performed to evaluate the action of drugs on the nervous system. Effects of the test drugs were compared with a standard drug—amitriptyline. Results were statistically evaluated by one-way analysis of variance followed by Bonferroni’s multiple comparison test. P≤0.05 was considered significant.Results: In forced swimming test, duration of immobility was significantly reduced in the standard and test drugs when compared to control group; however, it was not significant in all the four test groups as compared to that of amitriptyline-administered group (p>0.05). In tail suspension test, significant decrease (p<0.01) in the duration of immobility was observed with administration of drugs when compared to control group. Results of test groups were not found to be significant as compared to amitriptyline-treated group (p>0.05). Mean values of amitriptyline-, alendronate-, risedronate-, ibandronate-and etidronate-treated groups failed to show significant difference (p>0.05) when compared to control group suggesting homogeneity among the groups.Conclusion: Bisphosphonates appeared to have an antidepressant activity. More extensive research is required to substantiate and elucidate the role of bisphosphonates in behavioural disorders such as depression.

Background: Depression is a worldwide illness in the current population. Low levels of L-methylfolate are linked to depression. Present study evaluates the anti-depressive activity of acute and chronic administration of L-methylfolate per se in forced swimming test (FST) and tail suspension test (TST) and its interaction with escitalopram in albino mice.Methods: For this 30 swiss albino mice were divided randomly into five groups (n=6) as group I (control,10ml/Kg, p.o) - 2% suspension of gum acacia, group II - escitalopram suspension (10mg/kg, p.o), group III- L-methylfolate suspension (3mg/kg, p.o), group IV- L-methylfolate (3mg/kg, p.o) plus escitalopram (5mg/kg, p.o), group V- L-methylfolate(3mg/kg, p.o) plus escitalopram(10mg/kg, p.o), for forced swimming test. In tail suspension test again, mice were divided in five groups as above except that the dose of L-methylfolate was reduced to 1.25mg/kg. The pharmacologically validated models forced swimming test and tail suspension test were performed in mice to evaluate acute and chronic antidepressant activity of L-methylfolate and its combination with escitalopram respectively, after performing an acute toxicity study.Results: L-methylfolate and L-methylfolate plus escitalopram (10mg/Kg and 5mg/Kg, p.o) showed acute and chronic antidepressant activity in albino mice in FST and TST respectively. In human L-methylfolate is only active form of folic acid that readily crosses the blood brain barrier and utilized by the CNS. It regulates the bioavailability of critical cofactor BH4, required by enzymes synthesizing monoamines whose deficiency leads to depression.Conclusions: Hence, this study suggests antidepresant activity of L-methylfolate per se and as adjuvant with escitalopram when initiated from initiation of antidepressant therapy. Also, L-methylfolate opens the possibility of reducing the dose of antidepressant when used as adjuvant.
