Anti Psychotic

Context: Psychosis is a mental disorder, which is characterized as the reducing association with certainty and conviction. Around 1-2% of the world's population suffers from psychosis. The people affected by psychosis have hallucinations, delusions, forgetfulness, abolition, and anhedonia. Currently existing most of the anti- psychotic medications express the adverse drug reactions. Thus for the management of psychosis, satisfactory and adequate remedies are not available. Lagenaria siceraria (Molina) Standley (LS) (Cucurbitaceae) fruits, popularly known as “bottle gourd” (English) and “Lauki” (Hindi), exhibit numerous intrinsic therapeutic properties and actions. However limited scientific investigations have been performed to determine the neuroprotective potential of LS fruits. With this background, the present study was intended to investigate LS fruits for the assessment of anti-psychotic activity. Aims and Objectives: The rationale of this study was to evaluate the anti-psychotic activity of the phytocompound rich fractions of the methanolic extract of LS i.e., chloroform fraction of the methanolic extract (CFME), and acetone fraction of the methanolic extract (AFME) by using experimental models of cataleptic and stereotypic behavior in Swiss Albino mice. Materials and Methods: Haloperidol-induced catalepsy and apomorphine-induced stereotypy were the experimental screening tests performed for the assessment of anti-psychotic activity of the phytocompound rich fractions of methanolic extract of LS fruits at the doses of 100, 200, and 400mg/kg, p.o. in mice. Results: CFME and AFME, 100-400 mg/kg, significantly reduced cataleptic score and stereotypic behavior in mice, in dose-dependent manner. At doses of 200 and 400mg/ kg, AFME (P<0.001) exhibited more significant effect than CFME. In addition CFME and AFME did not generate motor dysfunction in mice. Preliminary phytochemical screening on CFME revealed the presence of saponins, phytosterols, and terpenoids, while phytochemical investigations on AFME indicated the presence of saponins, phenolic compounds, flavonoids and tannins. This was the first scientific report, which indicates that the LS fruits exhibit anti-psychotic action, confirming the folklore claims. Future investigations and studies should emphasize separation, characterization, and identification of the bioactive phytoconstituents and also on evaluating the precise mechanism involved in the anti-psychotic activity of both the fractions.

Rhododendron arboreum Smith. (Ericaceae), an evergreen small tree, is one of the 1000 species that belongs to genus Rhododendron distributed worldwide. In folk medicine, as various parts of this plant exhibit medicinal properties, it is used in the treatment of different ailments. The present study was designed to evaluate the potential anti-inflammatory and antinociceptive effects of methanolic extract of R. arboreum bark, followed by activity-guided fractionation of n-hexane, n-butanol, chloroform, ethyl acetate and aqueous fractions. The ethyl acetate fraction (200 mg/kg i.p.) showed the maximum analgesic effect (82%) in acetic acid-induced writhing, followed, to a less extent, by crude extract and chloroform fraction both at a dose of 200 mg/kg i.p. (65.09% and 67.89%, respectively). In carrageenan-induced mouse paw oedema, the crude extract and its related fractions displayed in a dose-dependent manner (50–200 mg/kg i.p.) an anti-inflammatory activity for all time-courses (1–5 hrs). For the active extract/fractions (200 mg/kg i.p.), the maximum effect was observed 5 h after carrageenan injection. These evidences were also supported by in vitro lipoxygenase inhibitory properties. In conclusion, R. arboreum crude methanolic extract and its fractions exhibited anti-inflammatory and antinociceptive effects. For these reasons, this plant could be a promising source of new compounds for the management of pain and inflammatory diseases.

Marrubium vulgare (Lamiaceae) is frequently used in traditional medicine to treat many illnesses from ancient times. Its beneficial effects include antibacterial, antioedematogenic, and analgesic activities. This study was designed to evaluate the antioxidant and anti-inflammatory activities of organic and aqueous extracts of the leaves, the flowers, the stems, and the roots of Marrubium vulgare. The total phenolic and flavonoid contents as well as the antioxidant and the anti-inflammatory effects of methanol, chloroform, ethyl acetate, and aqueous extracts have been investigated by using different in-vitro methods. It was found that the ethyl acetate extract from Marrubium vulgare stems had the highest total phenolic content, while the ethyl acetate extract from the leaves yielded a high concentration of flavonoids. The ethyl acetate extract from the stems exhibited the highest activity in scavenging of 2,2-diphenyl- 1-picrylhydrazyl (DPPH), as well as in protecting erythrocytes. The leaves aqueous extract exhibited the highest ferrous chelating activity and its methanolic extract was found to be the strongest inhibitor of lipid peroxidation in β-carotene bleaching assay. The leaves chloroform extracts as well as the flowers methanol, chloroform, and ethyl acetate extracts were found to decrease the pro-inflammatory tumor necrosis factor alpha (TNF-α) cytokine levels in a dose-dependent manner. On the other hand, the flowers methanolic extract and the leaves methanol, ethyl acetate, and aqueous extracts decreased the interleukin-1 beta (IL- 1β) release. It was also found that the methanol extract from the flowers and the chloroform extract from the stems of Marrubium vulgare inhibited interleukin-8 (IL-8) release. This study provides a scientific basis for the traditional use of Marrubium vulgare as an anti-inflammatory agent and for the plant to be considered as an important resource of natural antioxidants.

Abstract Background Reduced endothelial Tie2 expression occurs in diverse experimental models of critical illness, and experimental Tie2 suppression is sufficient to increase spontaneous vascular permeability. Looking for a common denominator among different critical illnesses that could drive the same Tie2 suppressive (thereby leak inducing) phenotype, we identified “circulatory shock” as a shared feature and postulated a flow-dependency of Tie2 gene expression in a GATA3 dependent manner. Here, we analyzed if this mechanism of flow-regulation of gene expression exists in vivo in the absence of inflammation. Results To experimentally mimic a shock-like situation, we developed a murine model of clonidine-induced hypotension by targeting a reduced mean arterial pressure (MAP) of approximately 50% over 4 h. We found that hypotension-induced reduction of flow in the absence of confounding disease factors (i.e., inflammation, injury, among others) is sufficient to suppress GATA3 and Tie2 transcription. Conditional endothelial-specific GATA3 knockdown (B6-Gata3tm1-Jfz VE-Cadherin(PAC)-cerERT2) led to baseline Tie2 suppression inducing spontaneous vascular leak. On the contrary, the transient overexpression of GATA3 in the pulmonary endothelium (jet-PEI plasmid delivery platform) was sufficient to increase Tie2 at baseline and completely block its hypotension-induced acute drop. On the functional level, the Tie2 protection by GATA3 overexpression abrogated the development of pulmonary capillary leakage. Conclusions The data suggest that the GATA3–Tie2 signaling pathway might play a pivotal role in controlling vascular barrier function and that it is affected in diverse critical illnesses with shock as a consequence of a flow-regulated gene response. Targeting this novel mechanism might offer therapeutic opportunities to treat vascular leakage of diverse etiologies.

AbstractAntifungal activity of Monothecabuxifolia methanolic extract and its various fractions were assessed against Macrophominaphaseolina, a soil-borne fungal pathogen of more than 500 vegetal species as well as rare and emerging opportunistic human pathogen. Different concentrations of methanolic extract (3.125 to 200 mg mL−1) inhibited fungal biomass by 39–45%. Isolated n-hexane, chloroform and ethyl acetate fractions suppressed fungal biomass by 32–52%, 29–50% and 29–35%, respectively. Triterpenes lupeol and lupeol acetate (1, 2) were isolated from n-hexane while betulin, β-sitosterol, β-amyrin, oleanolic acid (3–6) were isolated from chloroform fraction. Vanillic acid, protocatechuic acid, kaempferol and quercetin (7–10) were isolated from the ethyl acetate fraction and identified using various spectroscopic techniques namely mass spectroscopy and NMR. Antifungal activity of different concentrations (0.0312 to 2 mg mL−1) of the isolated compounds was evaluated and compared with the activity of a broad spectrum fungicide mancozeb. Different concentrations of mencozeb reduced fungal biomass by 83–85%. Among the isolated compounds lupeol acetate (2) was found the highest antifungal against M.phaseolina followed by betulin (3), vanillic acid (7), protocatechuic acid (8), β-amyrin (5) and oleanolic acid (6) resulting in 79–81%, 77–79%, 74–79%, 67–72%, 68–71% and 68–71%, respectively. Rest of the compounds also showed considerable antifungal activity and reduced M.phaseolina biomass by 41–64%.

Objective: The present study aim to investigate the anti-psychotic potential of pyrus communis in the rodents.Methods: The fresh juice of pyrus communis (Pear) was administered orally to rodents for 21 d and the anti-psychotic activity was assessed by in vitro methods viz ketamine induced stereotypic behaviour, pole climbing avoidance in rats and swim induced grooming behaviour experimental models. The biochemical estimation was done on 21 d.Results: The different concentrations of fresh pyrus communis juice was assayed. When pyrus communis juice (PCJ) was administered chronically for 21 d remarkably decreased ketamine induced falling, head-bobbing, weaving and turning counts. Administration of Pear juice significantly delayed the latency time taken by the animals to climb the pole in Cook’s pole climb apparatus. In swim induced grooming behaviour model, Pear juice significantly reduced swim induced grooming behaviour. Moreover, Pear juice significantly decreased the brain dopamine levels and inhibited acetyl cholinesterase activity. In the present study, Pear juice significantly enhanced reduced glutathione levels in the brains of mice, thereby reflecting enhanced scavenging of free radicals and in turn preventing occurrence of psychotic attack.Conclusion: The present study revealed that pyrus communis juice possessed significant anti-psychotic activity.
