Background and objectives
Otostegia persica (Labiatae) is an endemic plant of Iran and is used for its anti-inflammatory properties in folk medicine of Sistan and Baluchestan province. The aim of the present study was to investigate the anti-nociceptive and anti-inflammatory effects of O. Persica different fractions and identification of the natural compounds from the most active fraction.
MethodsTotal extract of O. Persica was fractionated with petroleum ether (PE), chloroform (CL), ethyl acetate (EA), n-butanol (BU) and methanol (ME). The analgesic activities of different fractions were determined by formalin test. Then, activity of effective fractions was investigated on carrageenan-induced paw edema assay. Finally, the compounds of effective fraction were isolated and their structures were elucidated.
ResultsAnti-nociceptive activity of EA and BU fractions (100 mg/kg) and ME fraction (100 and 200 mg/kg) demonstrated significant difference with normal saline during the second phase of the formalin test. ME fraction showed higher analgesic effects in comparison to indomethacin (p<0.05), with IC50 equal to 85.87 mg/kg. Among EA, BU and ME fractions which were selected for anti-inflammatory investigation, EA could not reduce rat paw edema after 6 h. The swelling inhibition percentage of ME was similar to that induced by indomethacin at the same time (p>0.05). Vicenin-2 and isorhamnetin-3-O-glucoside were elucidated from ME as the effective anti-inflammatory fraction.
ConclusionIt was concluded that the existence of flavonoids in O. persica extract could play an important role for its anti-nociceptive and anti-inflammatory effects similar to various non-steroidal anti-inflammatory drugs (NSAIDS) and inhibitors of nitric oxide synthase (NOS).

Squill [Drimia maritima (L.) Stearn] is an important medicinal plant that has been used for medicinal purposes such as cardiovascular diseases and asthma since ancient times. Bufadienolides are the main compounds of this plant and are responsible for some reported adverse effects. In order to reduce adverse effects, different methods like boiling with vinegar were applied by traditional practitioners. In the present study, the acute oral toxicity, cytotoxic effects, proscillaridin A content and antibacterial properties of methanol and vinegar extracts of squill white variety were compared for exploring the efficacy of traditional processing method.
MethodsDifferent doses of extracts (1000-5000 mg/kg) were administered during oral gavage in rats to analyze the acute oral toxicity. Cytotoxicity against HT-29, Caco-2 and NIH3T3 cell lines and antibacterial activity (Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis, Pseudomonas aeruginosa, Klebsiella pneumoniae and Escherichia coli) were investigated using MTT assay and conventional agar dilution method, respectively. Proscillaridin A content was evaluated in the extracts (vinager and methanol) by a validated high performance liquid chromatography method.
ResultsDuring the in vivo research no death or observed effect occurred in animals that received the extracts. Our results showed that all of the extracts exhibited no cytotoxic effects in experimented cell lines (IC50>1000 μg/mL). Proscillaridin A was only detected in the methanol extract and no significant antibacterial effect was detected in methanol extract.
ConclusionAccording to results of the present study, processing squill with vinegar according to traditional experiences can reduce possible the side effects of bufadienolids.

Ziziphora clinopodioides is a perennial herb and grows widely in west and northwest of Iran. The aerial parts are used as appetizer, carminative and antiseptic as well as for the treatment of medical conditions such as high blood pressure, asthma hyperhidrosis, palpitation and insomnia
MethodsThe aerial parts of Ziziphora clinopodioides Lam. were extracted by ethanol (70%) and fractionated by n-hexane. The n-hexane fraction was analyzed by GC and GC/MS. This fraction and the total extract were further investigated for in vitro cytotoxic activity against HT-29 (colon carcinoma), K-562 (leukemia), T-47D (breast ductal carcinoma) and NIH-3T3 (Swiss mouse embryo fibroblast) cells using MTT assay.
ResultsNineteen compounds were identified by GC/MS. The main constituents of the n-hexane fraction were pulegone (24.35%), menthol (14%) and menthone (9.61%). The results of cytotoxicity evaluation showed that the n-hexane fraction strongly exhibited cytotoxic activity against T-47D and K-562 cells with IC50 value of 77.41±12.89 and 80±2.56 μg/mL. The total extract did not show considerable activity against any of the cell lines in comparison to the n-hexane fraction.
ConclusionThe presence of compounds such as pulegone, menthol and menthone could explain the cytotoxic activity of the n-hexane fraction of Z. clinopodioides Lam on K-562, T-47D and HT-29 cell lines.

Urokinase plasminogen activator receptor (uPAR) and its ligands play a major role in many tumors by mediating extracellular matrix degradation and signaling cascades leading to tumor growth, invasion and metastasis. Recently we introduced uPAR decapeptide antagonist with cytotoxic effect on MDA-MB-231 cell line. In this study we assessed the alteration in uPAR downstream signaling following treatment with the peptide antagonist. In this regard, extracellular-signal-regulated kinase (ERK) and p38 from mitogen-activated protein kinase family and Bcl-2, Bim and Bax from Bcl-2 protein family were investigated. Our data revealed that the peptide caused p38 activation and low ERK activation. On the other hand, the peptide induced down-regulation of Bcl-2 and up-regulation of Bim without Bax modulation. Changes in target protein expression/activation explain the apoptotic property of the peptide and highlight its potential to be used as a therapeutic agent in cancerous cells expressing high levels of uPAR.

Sulfur mustard, a bifunctional alkylating agent, causes severe eye injury. The injury is a result of late inflammation, which is mediated by prostaglandins. Theoretically, inhibition of prostaglandins by reagents such as indomethacine could result in alleviation of clinical adverse effects. In this study, the protective effect of topically applied indomethacine against sulfur mustard toxicity was assessed on the rabbit eye. Ocular toxicity was studied by using light microscopy, electron microscopy and visual inspection methods. Methods used in this assay showed that 100 µL of indomethacine solution (0.5% W N) two hours before exposure and throughout the experiment could markedly decrease the toxic effects of mustard.
