  • In this study, the cDNA of a new peptide from the venom of the scorpion, Buthotus saulcyi, was cloned and sequenced. It codes for a 64 residues peptide (Bsaul1) which shares high sequence similarity with depressant insect toxins of scorpions. The differences between them mainly appear in the loop1 which connects the $\beta$-strand1 to the $\alpha$-helix and seems to be functionally important in long chain scorpion neurotoxins. This loop is three amino acids longer in Bsaul1 compared to other depressant toxins. A comparative amino acid sequence analysis done on Bsaul1 and some of $\alpha$-, $\beta$-, excitatory and depressant toxins of scorpions showed that Bsaul1 contains all the residues which are highly conserved among long chain scorpion neurotoxins. Structural model of Bsaul1 was generated using Ts1 (a $\beta$-toxin that competes with the depressant insect toxins for binding to $Na^+$ channels) as template. According to the molecular model of Bsaul1, the folding of the polypeptide chain is being composed of an anti-parallel three-stranded $\beta$-sheet and a stretch of $\alpha$-helix, tightly bound by a set of four disulfide bridges. A striking similarity in the spatial arrangement of some critical residues was shown by superposition of the backbone conformation of Bsaul1 and Ts1.

  • The MeOH extract of seeds of Cerbera odollam Gaertn. (Apocynaceae) was screened for its antibacterial, cytotoxic and neuropharmacological activities. The extract showed moderate anti-bacterial activity against Salmonella typhi, Streptococcus saprophyticus, and Streptococcus pyogenes. It exhibited high level cytotoxicity against brine shrimp ($LC_{50}$: $3\;{\mu}g/ml$). The extract potentiated pentobarbital induced sleeping time in mice which was further supported by the exploratory behavior test at dose of 25 mg/kg. The overall results tend to suggest the antibacterial, cytotoxic and CNS depressant activities of the extract.

  • Anti-depressant and anti-anxiety effects of Saccharomyces cerevisiae extract and its hydrolyzed fraction. The purpose of the present study was to examine the effect of Saccharomyces cerevisiae extract (SCE) and its hydrolyzed fraction (SCE-40) on depression and anxiety-related behaviors in mice. Actions of SCE and SCE-40 on serotonin, norepinephrine and GABAergic systems in the rat cerebral cortex membranes were also examined. SCE and SCE-40 significantly reduced the immobility time in the forced swimming and tail suspension test in mice. Duration time of the open arms in the elevated plus maze test was significantly increased in the SCE and SCE-40-treated groups, compared with the saline-treated control group. SCE and its fraction SCE-40 significantly inhibited serotonin and norepinephrine transporter and GABA receptor binding, compared to the saline-treated group. In addition, serotonin and norepinephrine reuptake were significantly suppressed by SCE and SCE-40. These results demonstrate that SCE and SCE-40 produce anti-depressant and anti-anxiety effects through enhancing central serotonin, norepinephrine and GABAergic transmissions. These results suggest that SCE and SCE-40 as functional food might prove to be an effective antidepressant and anti-anxiety agent.

  • Objectives : For the purpose of verifying the anti-depressant effect of Paeoniae Radix Rubra(PR), the expression of corticotropin-releasing factor(CRF), c-Fos and tyrosine hydroxylase(TH) was evaluated after performing the Forced Swimming Test(FST). Methods : Spraque-Dawley rats were ingested PR extract(100mg/kg, 400mg/kg, p.o.) for 3 times prior to FST. And the expression of corticotropin-releasing factor(CRF), c-Fos in the paraventricular nucleus(PVN) and tyrosine hydroxylase(TH) in the locus coelureus(LC) and ventral tegmental area(VTA) was measured immunohistochemically after FST. Results : The duration of immobility was significantly decreased in PR 100mg/kg Group and PR 400mg/kg Group, in comparison with the control group (p<0.001). The expression of CRF in the PVN was significantly decreased in PR 400mg/kg Group in comparison of the control group (p<0.05). The expression of c-Fos in the PVN was rather significantly increased in PR 100mg/kg Group in comparison with the control group, while almost no change was demonstrated in PR 400mg/kg Group. The expression of TH was significantly decreased in VTA in comparison with the control group (p<0.05), but the number of expression cells in LC was slightly decreased in case of PR 100mg/kg group while it was increased in case of PR 400mg/kg Group. Conclusion : Judging from the result of the aforementioned tests, Paeoniae Radix Rubra has decreased immobility. In addition, it has also decreased the expression of CRF and the expression of TH in VTA, while the expression of c-Fos and of TH in LC has no significance. Therefore, it is believed that Paeoniae Radix Rubra has an anti-depressant effect by decreased immobility through the reduced expression of CRF and TH in VTA.

  • The ether fraction obtained from dry fruit of Cornus officinalis was investigated for the anti-inflammatory action, acute toxicity and central nervous system activities. From several pharmacological examinations, it was found that the ether fraction suppressed considerably carrageenin edema at the dose of 600mg/kg p.o. in rats, inhibited the granuloma formation in rats as given 100mg/kg p.o. for 7 days and decreased the swelling of both of complete adjuvant injected and noninjected (contralateral) paws of the rats at the dose of 100mg/kg p.o. given for 14 days. The $LD_{50}$ of the fraction are estimated to be more than 2,000mg/kg p. o. and 642mg/kg i. p. in mice. And the fraction did not show any sedative, stimulative, analgesic and anticonvulsant action but exhibited hypothermic action. These results might be concluded that the ether fraction of Corni fructus showed anti-inflammatory action in both of acute and chronic type models without any considerable central nervous depressant activity and exhibited very weak acute toxicity in mice.

  • The therapeutic use of the wormwood plant Artemisia absinthium L. dates back to at least Roman times. There are more than 200 plants in the genus Artemisia- including southern wormwood, petite wormwood and Grande wormwood and encompasses about 500 species. The best-known species of wormwood is Artemisia absinthium, native to temperate Eurasia and North Africa and is branded for its extreme bitterness. It is a magical greens booze used as carminative to support healthy appetite, balances healthy flora, cleanse the digestive tract of parasite and toxins. It possesses anti-inflammatory, immunomodulatory, hepatoprotective, anti-helminthic and anti-depressant activity. Thujone excites nervous system when taken in small amount. Due to contrary history of wormwood, its application in individuals should be preceded by a thorough and cautious risk-benefit analysis. In this appraisal an attempt is done to validate scientifically, mentioned therapeutic potential of Artemisia absinthium in classical Unani literature using PubMed, Science Direct researches.
