Background: Depression is a common mental disorder results due to deficiency of neurotransmitter in the brain. Various medicinal properties of jatamansi are mentioned in Ayurveda. This study evaluated effect of hydro-alcoholic extract of rhizomes of Nordostachys jatamansi DC per se and in combination with fluoxetine in wistar albino rats and swiss albino mice.Methods: Animals of either sex were selected and randomly divided in test group. Jatamansi extract 10:1 and fluoxetine hydrochloride dissolved in distilled water were used. Animals were tested for forced swimming test, tail suspension test and locomotor after given test drug. Results were compared with control and analysed.Results: Nardostachys jatamansi DC, when given to rats showed dose dependent increase in number of rotation during forced swimming test in rats. During forced swimming test in glass jar statistically significant decrease in immobility was observed. Nardostachys jatamansi DC, when given to mice dose dependent statistically significant decrease in immobility time, swimming time and climbing observed. When given along with combination of fluoxetine it shows statistically significant difference in result, confirmed that it can have synergistic antidepressant activity. When used for locomotor activity in mice none of the test drugs significantly increase or decrease the locomotor activity.Conclusions: Jatamansi showed antidepressant like property in various tests conducted on rats and mice. It showed statistically significant result with increasing dose and had synergic effect when given along with fluoxetine.

Background: Depression is a group of disorders results from a combination of multiple etiologic factors- genetic, biochemical, psychodynamic and socio-environmental. A depression consists of following clinical features as sadness, apathy, changes in sleep pattern, impaired concentration, feeling of shame or guilt and thoughts of dying or death. Fluoxetine and riluzole both are used for the treatment of depression in human being. Fluoxetine is SSRI (selective serotonin reuptake inhibitors) and riluzole is anxiolytic and mood stabilizer.Methods: Healthy male albino rats weighing between 150-200 grams were taken for the present study. Study animals were divided into three groups randomly with each group consisting of ten animals. Drugs were powdered with help of mortar and pestle and mixed in gum acacia solution. Appropriate volume of the freshly prepared solution was administered orally daily between 9 am to 10 am to all animal as per their individual body weight. Group A administered 1ml of 0.9% normal saline orally and serves as control group. Group B administered 0.4 mg of fluoxetine orally. Group C administered 2 mg of riluzole orally. Animals were evaluated for antidepressant activity using model- forced swimming test.Results: The results in the forced swimming test were assessed by duration of immobility in last 4 minutes of total 6 minute test duration. Antidepressant activity is indicated by the reduction in the duration of immobility i.e. lesser the duration more the efficacy. The results have been expressed as mean±standard deviation of duration of immobility in seconds during 6 minute period.Conclusions: There was significant difference in antidepressant activity of fluoxetine with antidepressant activity of riluzole. Riluzole showed antidepressant activity after two weeks of starting the drugs.

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.

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

exposure to chronic stress is an important factor of neurodegeneration. Forced swimming test is a common model for chronic stress which needs validation in terms of duration of exposure and correlation of behavioural, histological and anti-oxidant status. Adult wistar albino rats (150-200 g) of both sexes were divided into two groups. Group I treated as control and Group II animals were subjected to forced swimming test for 30 minutes daily. On different days (0, 3,7,15 and 30) effect on behavioural, histological and anti-oxidant status was evaluated. Swimming stress of 30 minutes daily for 15 days significantly (p<0.05) decreased the time of fall in rotarod, locomotor activity in actophotometer, number of correct entries in radial maze, superoxide dismutase (SOD) level and significantly (p<0.05) increased the malondialdehyde (MDA) content along with prominent tissue degeneration in brain, heart, liver and kidney. The present study reveals that 30 minutes exposure to forced swimming for 15 days can be a novel model of chronic stress as it results in significant alterations in behavioural, histological and antioxidant status.
