First Time

We investigated the effects of gestational exposure to fenproporex, one of the most used anorectic drugs in Brazil, on the behavior of adolescent and adult pups (30 and 60 days of age, respectively). Pregnant Swiss mice were treated daily, by gavage, with 15 mg/kg of fenproporex chloride or water during the whole gestational period. Male pups were submitted to open-field, forced swimming test, tail suspension test and fenproporexinduced stereotyped behavior. The results demonstrated that gestational exposure to fenproporex induces antidepressant-like effect and decreases fenproporexinduced stereotyped behavior in both adolescent and adult pups. Moreover, fenproporex-exposed adolescent pups tended (P–0.06) to be more active than control pups. Our data show, for the first time, that gestational exposure to fenproporex leads to long-lasting behavioral toxicity in male mice characteristic of altered dopaminergic transmission.

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

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.

Adverse early life experiences can negatively affect behaviors later in life. Maternal separation (MS) has been extensively investigated in animal models in the adult phase of MS. The study aimed to explore the mechanism by which MS negatively affects C57BL/6N mice, especially the effects caused by MS in the early phase. Early life adversity especially can alter plasticity functions. To determine whether adverse early life experiences induce changes in plasticity in the brain hippocampus, we established an MS paradigm. In this research, the mice were treated with mild (15 min, MS15) or prolonged (180 min, MS180) maternal separation from postnatal day 2 to postnatal day 21. The mice underwent a forced swimming test, a tail suspension test, and an open field test, respectively. Afterward, the mice were sacrificed on postnatal day 31 to determine the effects of MS on early life stages. Results implied that MS induces depression-like behavior and the effects may be mediated partly by interfering with the hippocampal GSK-3β-CREB signaling pathway and by reducing the levels of some plasticity-related proteins.

Objective: To evaluate the possible antidepressant effects of alpha-terpineol in rodents. Material and Methods: Depression levels were analyzed by comparing the total immobility time presented by the animals of the experimental groups in the test session, using the Forced Swimming Test and the Tail Suspension Test. The parameters of locomotion (central, peripheral and total) and motor coordination were evaluated in the Open Field Test and in the Rota Rod Test, respectively. In the second stage, the involvement of the noradrenergic system in the antidepressant action of alpha-terpineol in Forced Swimming Test was investigated. Results and Discussion: After performing the experimental tests, it was observed that the animals that received alpha-terpineol had reduced immobility time in Forced Swimming Test and Tail Suspension Test, compared to the other groups. In the Open Field Test and Rota-rod, the mice showed, respectively, good exploratory activity and motor coordination during the tests. In addition, the study of the Noradrenergic System proved to be a promising mechanism used during its antidepressant action. Conclusion: In view of the results of the experimental tests, alpha-terpineol presented similar responses to those found in other monoterpenes investigated in the literature. Thus, it is shown as a promising antidepressant to be used clinically in humans, with less side effects and low production cost.

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>

Gabapentin as an anticonvulsant drug also has beneficial effects in treatment of depression. Previously, we showed that acute administration of gabapentin produced an antidepressant-like effect in the mouse forced swimming test (FST) by a mechanism that involves the inhibition of nitric oxide (NO). Considering the involvement of NO in adenosine triphosphate (ATP)-sensitive potassium channels (KATP), in the present study we investigated the involvement of KATP channels in antidepressant-like effect of gabapentin. Gabapentin at different doses (5–10 mg/kg) and fluoxetine (20 mg/kg) were administrated by intraperitoneal route, 60 and 30 min, respectively, before the test. To clarify the probable involvement of KATP channels, mice were pretreated with KATP channel inhibitor or opener. Gabapentin at dose 10 mg/kg significantly decreased the immobility behavior of mice similar to fluoxetine (20 mg/kg). Co-administration of subeffective dose (1 mg/kg) of glibenclamide (inhibitor of KATP channels) with gabapentin (3 mg/kg) showed a synergistic antidepressant-like effect. Also, subeffective dose of cromakalim (opener of KATP channels, 0.1 mg/kg) inhibited the antidepressant-like effect of gabapentin (10 mg/kg). None of the treatments had any impact on the locomotor movement. Our study, for the first time, revealed that antidepressant-like effect of gabapentin in mice is mediated by blocking the KATP channels.
