  From the ethyl acetate and methanol extract of the aerial parts of Satureja atropatana Bonge, which belongs to the Lamiaceae family, four flavonoids were isolated. Their structures were determined to be 5,6,3’-trihydroxy-7,8,4’-trimethoxyflavone (1), 5,6-dihydroxy-7,8,3’,4’-tetramethoxyflavone or 5-desmethoxynobiletin (2), 5,6,4’-trihydroxy-7,8,3’-trimethoxyflavone or thymonin (3) and luteolin (4) using 1H and 13C-NMR and MS spectra. Brine shrimp cytotoxicity effects of the crude extracts and isolated compounds were examined. Berberine hydrochloride (LC50 = 26 g mL-1) was used as a positive control. Among them, compounds 2 (199 g mL-1) and 3 (157 g mL-1) were effective against Artemia salina larva.

  The genus Salvia (Lamiaceae) contains more than 50 shrub species in Iran, and Salvia limbata C.A. Meyer grows widely in the north and central parts of the country. Six flavones and rosmarinic acid were isolated from the ethyl acetate and methanol extracts of the flowered aerial parts of S. limbata collected from Semnan province. The separation process was carried out using several chromatographic methods. Structural elucidation was based on NMR data, in comparison with those reported in the literature. The isolated compounds were identified as ladanein (1), salvigenin (2), luteolin 7-methyl ether (3), cirsiliol (4), eupatorin (5), luteolin 7-O-glucoside (6) and rosmarinic acid (7). Some of these flavonoids have been reported to show antibacterial and cytotoxic activities.

  Several Ferula (Umbelliferae) species have been used in Iranian traditional medicine as antiflatulent, antispasmodic, anticonvulsant, expectorant, etc. In the present study, cytotoxicity and anticonvulsant activity of the methanol extracts from several Ferula species were evaluated. Air-dried samples of different parts of these plants (Ferula diversivittata Regel & Schmalh. (roots), Ferula persica Willd. (aerial parts), Ferula ovina (Boiss.) Boiss. (roots), Ferula badrakema Kos.-Pol. (roots), Ferula diversivittata (flowers), Ferula latisecta Rech. F. & Aell. (roots), and Ferula badrakema (fruits)) were macerated with methanol for 3 days. The mixtures were then filtered, concentrated and dried. For determination of the cytotoxicity of the extracts and also the oleo-gum-resin of F. assafoetida L., the brine shrimp (Artemia salina) was employed as a model assay system since it provides a convenient in-house pre-screening method for evaluating general cytotoxicity. The methanol extracts of different Ferula species and the oleo-gum-resin of F. assafoetida exhibited cytotoxic effect with LC50 values in the range of 6-321 μg/mL. For the anticonvulsant testing, seizure was induced by injection of pentylenetetrazole (PTZ), 90 mg/kg intraperitoneally (i.p.). This dose was given to 10 groups, each consisting of 6 mice, which were pretreated i.p. with the extracts (300 mg/kg), Diazepam (10 mL/kg) or saline (10 mL/kg). The results showed that none of the tested Ferula species can prevent PTZ-induced seizure at the used dose. In conclusion, all of the extracts and the oleo-gum resin of F. assafoetida showed dose-dependent cytotoxicity which was highest in F. badrakema fruits and lowest in F. badrakema roots. Our findings also revealed that the methanol extracts and F. assafoetida oleo-gum resin do not possess anticonvulsant activity.

  Today sport has become an important part of life in society, on the other hand, with regard to the role of football, its impact on various forms of social life and its positive and negative functions make it something interesting for the researchers of human sciences, especially sociologists. This study aims to investigate the influence of excitement and violence in football (checking audience and fans of Esteghlal and Persepolis) in 1394. This study is a descriptive-analysis of cross-sectional. It is based on survey, theory of social learning, theory of Robert Merton and Norbert Elias and subculture of delinquency. The population of study is 80000 football fans of Esteghlal and Persepolis that with the respect to Cochran formula, 500 people has been selected as sample of the study. Snowball sampling is used for leader’s selection and simple random sampling for viewers. The study shows that there is a meaningful relationship between family’s pattern with thrill-violence, friend’s pattern with thrill-violence, the pattern of media with thrill-violence and age of the respondents with the level of thrill and violence.
