Hydroethanolic Extract

Background: Anxiety is a protective reflex and the most common disorder. This study was done to evaluate the effect of anxiolytic property of oil and aqueous fractions isolated from hydroethanolic extracts of Coriandrum sativum leaf by novel freezing technique with swiss albino mice.Methods: Hydroethanolic extract of Coriandrum sativum leaves was prepared. Oil and aqueous part were separated with freezing technique. Animals were divided into six groups. Ist group served as control and 1% DMSO was administered orally. IInd to Vth group were administered with Coriandrum sativum oil fraction and Coriandrum sativum aqueous fraction at doses of 400 and 800 mg/kg orally. VIth group was treated with diazepam 1mg/kg orally. After one hour of dosing, battery of test was done viz, elevated plus maze (EPM), light dark arena, photo actometer and rotarod.Results: One-way analysis variance (ANOVA) followed by Dunnett's multiple comparison test was used for statistical analysis. Anxiolytic property was found to be in the following order diazepam>coriandrum sativum aqueous 800>coriandrum sativum aqueous 400>coriandrum sativum oil 800>coriandrum sativum oil 400 mg/kg. All the extracts were devoid of adverse effects of motor coordination.Conclusions: Coriandrum sativum leaf possesses anxiolytic effect. The aqueous fraction of the hydroethanolic extract of the Coriandrum sativum leaf was found to be potent and further analysis may lead to identification of active compounds. The findings that the extract is non-sedating anxiolytic and is of good safety index are promising.

Background: Solanum aethiopicum (L.), family Solanaceae, is known as garden eggs. The fruit is used in the treatment of insomnia, diabetes and constipation. Objective: The aim of this study was to evaluate anxiolytic-like activity of fractions obtained from crude methanol extract of Solanum aethiopicum fruit. Method: Acute toxicity testing was conducted according to the OECD guidelines 420 via oral and intraperitoneal routes (ip). n-Hexane (HF), chloroform (CHF), ethyl-acetate (EAF), n-butanol (BF) and residual aqueous fraction (RAF) at doses of 25, 50 and 100 mg/kg ip were experimented using the open field, elevated plus maze, staircase, light dark box and hole-board tests. Results: Results: In open field test, there was statistically significant increase in frequency of central square entry by EAF 25mg/kg, 50mg/kg and 100mg/kg and RAF 25mg/kg, 50mg/kg and 100mg/kg all at p<0.05 compared to distilled water (D/W) group. Elevated plus maze test showed statistically significant increases in open arm entry and duration by CHF 25mg/kg, RAF 25mg/kg and 50mg/kg again at p<0.05. Also, in the staircase test, statistically significant decrease in frequency of rearing with no effect on step climbing was observed by RAF 25mg/kg (p< 0.05) compared to D/W. Light and dark box test produced increased light box entry and duration by EAF 25mg/kg, RAF 25mg/kg and 50mg/ kg at p<0.05. Furthermore, the hole -board test showed statistically significant increases in number of head dips by EAF 50mg/kg and 100mg/kg as well as RAF 25mg/kg, 50mg/kg and 100 mg/kg at p<0.05. Conclusion: The fractions obtained from Solanum aethiopicum fruits possesses anxiolytic-like activity.

Abstract ObjectiveAnxiety behavior is regulated by different neurotransmitter systems. There has been no direct relationship between endocannabinoid and cholinergic systems on anxiety in previous studies. This study investigated the effects of each of these systems separately and simultaneously using Donepezil (Cholinesterase inhibitor) and URB-597 (endocannabinoid degrading enzyme inhibitor) on anxiety-like behavior. MethodEighty-eight male mice were divided into eleven groups (n=8) including control (saline), diazepam (0.3 mg /kg), URB-597 (0.1, 0.3, or 1 mg /kg), donepezil (0.5, 1 or 2 mg/kg) and the combination of the two drugs at low, medium and high doses. All treatments were injected intraperitoneally 30 minutes before the elevated plus maze test. ResultsSeparate administration of URB597, donepezil or diazepam increased the number and time spent of open arms compared to the control group. Concurrent administration of URB and donepezil at low, medium and high doses did not change the number of open arms entries compared to the control group, but they reduced the number of entries to the closed arms. ConclusionsThese results suggest that strengthening any cholinergic or endocannabinoid system has anxiolytic effect similar to diazepam. However, the interaction of these two systems has fewer anxiolytic effects compared to the effects of each alone. It seems that these drugs alone may represent a strategy for the treatment of anxiety disorders.

Gardenia Jasminoides Ellis

Gardenia jasminoides Ellis is a famous fragrant flower in China. Previous pharmacological research mainly focuses on its fruit. In this study, the essential oil of the flower of ‘Shanzhizi’, which was a major variety for traditional Chinese medicine use, was extracted by hydro distillation and analyzed by GC-MS. Mouse anxiety models included open field, elevated plus maze (EPM), and light and dark box (LDB), which were used to evaluate its anxiolytic effect via inhalation. The involvement of monoamine system was studied by pretreatment with neurotransmitter receptor antagonists WAY100635, flumazenil and sulpiride. The monoamine neurotransmitters contents in the prefrontal cortex (PFC) and hippocampus after aroma inhalation were also analyzed. The results showed that inhalation of G. jasminoides essential oil could significantly elevated the time and entries into open arms in EPM tests and the time explored in the light chamber in LDB tests with no sedative effect. WAY100635 and sulpiride, but not flumazenil, blocked its anxiolytic effect. Inhalation of G. jasminoides essential oil significantly down-regulated the 5-HIAA/5-HT in the PFC and reduced the 5-HIAA content in hippocampus compared to the control treatment. In conclusion, inhalation of gardenia essential oil showed an anxiolytic effect in mice. Monoamine, especially the serotonergic system, was involved in its anxiolytic effect.

Antidepressant Effects

BackgroundGabapentin, a third-generation antiepileptic drug, is a structural analogue of γ-aminobutyric acid, which is an important mediator of central nervous system. There is clinical data indicating its effectiveness in the treatment of psychiatric illnesses such as bipolar disorder and anxiety disorders.ObjectivesWe aimed to investigate the antidepressant and anxiolytic-like effects and mechanisms of gabapentin in rats.Material and MethodsFemale Spraque–Dawley rats weighing 250±20 g were used. A total of 13 groups were formed, each containing 8 rats: gabapentin (5, 10, 20, 40 mg/kg), amitriptyline (10 mg/kg), sertraline (5 mg/kg), diazepam (5 mg/kg), ketamine (10 mg/kg), gabapentin 20 mg/kg was also combined with amitriptyline (10 mg/kg), sertraline (5 mg/kg), diazepam (5 mg/kg) and ketamine (10 mg/kg). All the drugs were used intraperitoneally as single dose. Saline was administered to the control group. Elevated plus maze and forced swimming tests were used as experimental models of anxiety and depression, respectively.ResultsIt was observed that gabapentin showed an anxiolytic-like and antidepressant-like effect in all doses in rats. Its antidepressant effect was found to be the same as the antidepressant effects of amitriptyline and sertraline. There was no change in the antidepressant effect when gabapentin was combined with amitriptyline and ketamine, but there was an increase when combined with sertraline and diazepam. Gabapentin and amitriptyline showed similar anxiolytic effect, whereas ketamine and diazepam had more potent anxiolytic effect compared with them.ConclusionsThese data suggest that gabapentin may possess antidepressant- and anxiolytic-like effects.

INTRODUSTION: Sibutramine has been described as a drug recommended for treatment of obesity, since it has the ability to inhibit the reuptake of serotonin and noradrenaline in the central nervous system, thereby increasing energy expenditure. OBJECTIVE: Investigate the anxiogenic and anxiolytic effects of acute and chronic treatment with sibutramine in rats submitted to the task of the elevated plus-maze. METHODS: Diazepam was used as a positive control for the anxiolytic effect, and the task of the elevated plus-maze showed sensitivity to detect the effect. In the chronic treatment, sibutramine was ingested for a period of two months. RESULTS: The acute and chronic treatments at the studied dose, which is described to produce a maximum effect of anti-obesity in rats, did not interfere with anxiety. CONCLUSIONS: The acute and chronic administration of sibutramine is not related to anxiolytic or anxiogenic effects.

Proceeding from the proposition about the high productivity of the search of neuropsychotropic substances among the derivatives of natural neuromediators, a study of neuropsychopharmacological effects of the derivative of the glutamic acid, RGPU-197 compound was carried out. The study was carried out on the he-rats of the Wistar line using the following tests: “open field”, elevated plus maze, conditioned passive-avoidance response, the test of extrapolational deliverance, the test of hanging mice by tails; and also the methods of statistic analysis: rank univariate analysis of Cruscal-Wallace, the Dunn multiple comparison test /the multiple comparison test of Dunn, the x2 criterion. The RGPU-197 compound significantly (p<0,05, p<0,01) decreases the duration of immobilization of the animals and expands the latent period of its approach in the test of hanging mice by tails — it possesses antidepressant activity; increases the quantity of the visits of the centre of the open field, the quantity of attendings of the open hoses of elevated plus maze and the time of stay in them — it shows anxiolytic action; increases the quantity of crossed squares in the open field and the quantity of crossings between the hoses of elevated plus maze — it possesses activating effect; during the displays of the avoidance reflex it expands the latent period of the first period of entering the dark compartment and the quantity of enterings of it in conditioned passive-avoidance response, reduces the latent period of diving under in the test of extrapolational deliverance — it shows nootropic action. According to the intensity of antidepressant action RGPU-197 doesn’t yield to melipramin, anxiolytic and activating effects significantly (p<0.05) excels phenibutum and doesn’t yield to it by nootropic activity. Thus, the new derivative of glutamate, the RGPU-197 compound, possesses the marked antidepressant, anxiolytic and activating effects, as well as nootropic activity.
