| 2 | Protoscolicidal and immunomodulatory activity of Ziziphora tenuior extract and its fractions显示文摘Objective:To evaluate the scolicidal and immunomodulatory effect of the Ziziphora tenuior(Z.tenuior) extract and its fractions.Methods:Protoscolices were treated with six concentrations(3,5,10,25,50,and 100 mg/mL) of Z.tenuior extract and its fractions(ethanol,petroleum ether,ethyl acetate and chloroform) in periods of 10,20,30,40,50 and 60 minutes,and viability of protoscolices was evaluated using the 1.0%eosin.To examine the immunomodulatory effects of Ziziphora and its fractions on macrophage cells,the non-toxic concentration of extract and different fractions determined by MTT assay,and the Griess reaction was used to measure the level of nitrite as an indicator of nitric oxide by the macrophage cells in 10,100 and 200 μg/mL in 24 hours at 37 ℃.Results:In this study,the Z.tenuior extract at 10 mg/mL concentration was able to kill all protoscolices during 20 minutes.By increasing the concentration to 25 mg/mL,the scolicidal time reduced to 10 minutes.Regarding the effect of different fractions of Z.tenuior,the ethanolic fraction showed the highest scolicidal activity.The extract demonstrated an inhibitory effect on the activity of macrophages and reduced nitric oxide production.Although the petroleum ether and ethanolic fractions of the extract reduced nitric oxide production,nevertheless,this effect was only significant at 10 and 100 ug/mL concentrations(P<0.05).Conclusion:The Z.tenuior extract and its fractions were effective against protoscolices yet the effect of total extract was considerable.Our findings indicates that the extract and its ethanolic and petroleum ether fractions could have anti-inflammatory properties. | Mojtaba Shahnazi Abbas Azadmehr Ammar Andalibian Reza Hajiaghaee Mehrzad Saraei Mahmood Alipour | 2016 | Asian Pacific Journal of Tropical Medicine2016，9，11： | 1 |
| 3 | Usage of Iranian scoria for copper and cadmium removal from aqueous solutions显示文摘The competitive removal of copper and cadmium from aqueous solutions using scoria has been investigated. Scoria was characterized by various methods, such as XRD, XRF, FT-IR and SEM. The results show that scoria sample contained augite, enstatite, diopside, and olivine. These minerals were separated from each other and each mineral was then subjected to the adsorption experiments. It was found that the main absorbent constituent in scoria was augite. Finally, statistical experimental method was used to optimization of adsorption conditions(Initial concentration of copper and cadmium ions, the amount of scoria and temperature) for removal of Cu(II) and Cd(II) ions from solution in optimum conditions. The optimum conditions are obtained as follows: concentrations of Cu(II) and Cd(II) of 400×10-6 and 554×10-6, respectively; amount of scoria of 7 g; temperature of 38 °C. Under these conditions Cu(II) and Cd(II) ions are absorbed onto the scoria more than 79% and 16%, respectively. | Sara Seyfi Amir Reza Azadmehr Mahdi Gharabaghi Abbas Maghsoudi | 2015 | Journal of Central South University2015，22，10： | 0 |
| 4 | Evaluating the effect of Myrtus communis on programmed cell death in hydatid cyst protoscolices显示文摘Objective: To evaluate the possible involvement of programmed cell death strategy in hydatid cyst protoscolices following treatment with Myrtus communis(M. communis) as an herbal medicine.Methods: Protoscolices were aseptically collected from sheep liver hydatid cysts. Evaluating the effect of M. communis extract on programmed cell death and increased activity of caspases 3, 8, and 9 in hydatid cyst protoscolices was conducted by treating the protoscolices with different concentration(5, 50, and 100 mg/mL) of M. communis extract at37C and 5% CO2 for 4 h by using the Bradford test and ELISA commercial kits.Results: The extract of M. communis at all concentrations led to initiation of programmed cell death in protoscolices and this effect, was only significant at 50 and 100 mg/mL concentrations, compared to the negative control(P < 0.05). Also, the activity of caspases3, 8, and 9 in hydatid cyst protoscolices, was shown that the extract at all 3 concentrations could only increase the activity of caspases 3 and 9. Moreover, a significant increase in the activity of caspase 3 was only observed at concentrations 50 and 100 mg/m L by 37.00%and 66.19% while a significant increase in the activity of caspase 9 at the same concentrations was observed by 20.89% and 63.67%, respectively(P < 0.05).Conclusions: The extract of M. communis at different concentrations could increase the activity of caspases 3 and 9 and caused programmed cell death in hydatid cyst protoscolices however, this effect was significant at high concentrations of the extract. | Mojtaba Shahnazi Abbas Azadmehr Moazzam Dosti Jondabeh Reza Hajiaghaee Reza Norian Hamidreza Aghaei Mehrzad Saraei Mahmood Alipour | 2017 | Asian Pacific Journal of Tropical Medicine2017，10，11： | 0 |
