Neurochemical Changes

Diabetes mellitus is accompanied by hormonal and neurochemical changes that can be associated with anxiety and depression. I investigated the antidepressant effect of simvastatin (SMV) on diabetic rats. Rats were divided into control (CTR) and streptozotocin-induced diabetic (STZ) groups and were orally administered 0, 5, or 10 mg/kg of SMV daily for 14 days, then exposed to the forced swimming test (FST). Our results showed that diabetic rats had higher immobility duration than the CTR rats, and SMV decreased this depressive-like behavior in the diabetic rats. However, clomipramine lowered the immobility time in the CTR and STZ rats. STZ decreased serotonin concentration in the hippocampus, which was reversed by SMV and clomipramine. The dopamine concentration in the hippocampus decreased in the STZ groups compared with the CTR groups. However, SMV and clomipramine had no significant effect on the dopamine levels in either the CTR or STZ groups. Corticosterone levels were increased in the untreated STZ group; SMV and clomipramine significantly decreased corticosterone levels in the STZ groups, but had no effect on the CTR groups. In conclusion, SMV exerts an antidepressant-like effect on diabetic rats that are submitted to the FST. The antidepressant-like effect of SMV in the FST appears to be mediated, at least in part, by the biochemical changes to the blood levels of corticosterone and of serotonin concentration in the hippocampus.

Objective: To evaluate the antidepressant effect of Bauhinia blakeana and a standardized fraction in the forced swimming test (FST) on mice with neuroinflammation induced with lipopolysaccharides (LPS). Materials and Methods: Evaluation of the antidepressant effect of Bauhinia blakeana hydroalcoholic extract (BbHA) and its fractions was carried out in behavioral tests on mice with LPS-induced neuroinflammation. Results: BbHA had a significant antidepressant effect, measured on healthy mice in the FST. Bio-guided chemical separation of the extract produced a methanolic fraction (BbMe), which decreased the immobility time in FST. In this test, the intraperitoneal administration of LPS induced depression in mice, and BbHA and BbMe counteracted this effect, significantly decreasing the induced depression. Quantification of inflammatory mediators (IL-10, IL-4, IL-6, IL-1β, and TNF-α) in the brain demonstrated that BbHA and BbMe effectively decreased the effect of LPS on the brain concentration of all measured cytokines. Conclusions: Bauhinia blakeana produced an antidepressant effect, while BbMe also exerted a modulating effect, on the damage induced by LPS. Rutin, a glycosylated flavonoid, was identified as the main compound in the active fraction, which could mediate in the antidepressant and immunomodulatory effect.

Novel naphthoquinone derivatives bearing 1,2,4-triazine- (4a–b) and 1,2,4-triazole (5a–e) pharmacophores have been synthesized; their structure was confirmed by electrospray ionization mass spectrometry, 1H NMR, 13C NMR, IR spectroscopies and elemental analysis. The obtained heterocyclic compounds were estimated for their anticonvulsant activity on models of chemical- and electrical-induced seizures in pentylenetetrazole (PTZ) and maximal electroshock (MES) tests, respectively. Forced swimming test was used to evaluate the antidepressant effect of the naphthoquinone derivatives under study. Compounds 4a–b and 5a–e (100 mg kg–1) demonstrated anticonvulsant action comparable with valproic acid in PTZ-test and prevented the death of 100% of mice in MES model at 3 h and 24 h after oral administration. Moreover, these derivatives showed prolonged antidepressant-like properties, significantly reducing the duration of immobility time in comparison with the reference drug amitriptyline.

Underlying Mechanisms

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.

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

Antiparkinsonian activity of Cleome gynandra (CG) was evaluated and chemical constituents were isolated. The results of the present study showed that spontaneous motor activity, retention time and number of head drippings were decreased, whereas immobility time in Tail suspension (TST) and Forced swimming test (FST) were increased in MPTP treated animals, while they were significantly (P<0.001) increased and (P<0.01) decreased with various extracts of CG. Dopamine, serotonin (P<0.001), epinephrine (P<0.01) and glutathione levels were significantly decreased and lipid peroxidation was increased in MPTP treated groups, while their levels were significantly (P<0.001) increased and decreased with various extracts of CG in a dose dependant manner as compared to MPTP, L-dopamine and control groups. Ethanolic leaf extract of CG leads to isolation of triterpenoid, flavone and anthocyanidin - O- methylated flavonoids, which were characterized by using spectroscopic investigation methods like FTIR, NMR and MS.

AbstractBackgroundInterferon-α (IFNα) therapy causes psychiatric side effects, including depression that may result in poor compliance of therapy. It is important to find alternative therapies for the prevention of IFNα induced depression. Non-steroidal anti-inflammatory drugs (NSAIDs) have been useful in depressive disorder. Therefore the effects of celecoxib, ibuprofen, and indomethacin were evaluated following IFNα-induced depression in mice.MethodsMale albino mice weighing 26 ± 2 g were used. Depression was induced by IFNα (16 × 105 IU/kg, SC) for six consecutive days. Animals were first subject to the locomotor test, then the splash test and finally the forced swimming test (FST) on the 7th day. The NSAIDs were administered (IP) either one single dose before the test, or simultaneously with IFNα.Resultslocomotor activity was only impaired by ibuprofen high dose (75 mg/kg), thus it was not further evaluated. Following IFNα therapy depression-like behaviors were observed; significant changes during the splash test (grooming time 24 ± 7 sec vs. control 63 ± 7 sec), the FST (immobility time 166  ± 15 sec vs. control 128  ± 6 sec), and sucrose preference reduced to 64 ± 0.8%. The NSAIDs noticeably reduced the immobility time in FST, while grooming time was increased. Celecoxib and indomethacin single doses were effective while ibuprofen showed better antidepressant effects when it was administered along with IFNα.ConclusionsThe NSAIDs were able to prevent IFNα induced depression in mice. NSAIDs administration with IFNα does not interfere with clinical benefit effects of IFNα and they could also be useful to prevent IFNα psychiatric side effects, thus further clinical trials are suggested.

Diabetic neuropathy, which affects 7 to 9% of the world’s population and that is usually accompanied by anxiety and depression, is chronic pain that results from impaired function of the central or peripheral nervous system. This study aimed at evaluating the antihypernociceptive, antiallodynic, anxiolytic, and antidepressant effects of Dissotis thollonii extracts. Diabetic neuropathy was induced by intraperitoneal injection of streptozotocin (200 mg/kg) in mice. The aqueous and ethanol extracts (250 and 500 mg/kg) were administered orally. Hyperalgesia (thermal and chemical), allodynia (mechanical and thermal), anxiety (high plus labyrinth, light-dark box, and social interaction), and depression (open field test, suspension test tail, and forced swimming test) were evaluated, and then the levels of some cytokines and growth factors were determined. The aqueous and ethanol extracts of Dissotis thollonii demonstrated significant antihypernociceptive (inhibition of hyperalgesia and allodynia), anxiolytic, and antidepressant activities in mice made diabetic by STZ. The extracts also significantly inhibited (p<0.001) the levels of TNF-α, IL-1β, and IL-6 in the blood as well as the levels of TNF-α, IL-1β, IL-6, IGF, and NGF in the sciatic nerve. This study shows that the extracts of Dissotis thollonii have antihypernociceptive and neuroprotective effects which could be linked to the inhibition of proinflammatory cytokines and growth factors in the blood and the sciatic nerve.
