| 1 | In-vitro antimicrobial activity screening of some ethnoveterinary medicinal plants traditionally used against mastitis,wound and gastrointestinal tract complication in Tigray Region,Ethiopia显示文摘Objective:To screen the antibacterial activity of nine ethnoveterinary plants traditionally used for the treatment of mastitis,wound and gastrointestinal complications.Methods:Hydroalcoholic exctracts of medicinal plants namely,Achyranthes aspera(A.aspera) L.(Family Asparagaceae),Ficus caria(F.caria)(Family Moraceae).Malvi parviflora(M.parviflora)(Family Malvaceae),Vernonia species(V.species) docal name Alakit.Family Asteraceae),Solatium hastifolium(S.hastifolium)(Family Solanaceae),Calpurinia aurea(C.aurea)(Ait) Benth(Family Fabaceae),Nicotiana tabacum(N.tabacum) L.(Family Solanaceae),Ziziphus spina-christi(Z.spina-christi)(Family Rhamnaceae).Croton macroslachys(C.macrostachys)(Family Fuphorhiaceae).were screened against clinical bacterial isolates of veterinary importance from October 2007 to April2009.The antibacterial activity was tested using disc diffusion at two concentrations(200 mg/mL and 100 mg/mL) and broth dilution methods using 70%methanol macerated leal extracts.Results:With the exception ol S.hastifolium all plant extracts exhibited antibacterial activity.Among the medicinal plants tested C.aurea.C.macrostachyus,A.aspera,N.tabacum and vcrnonia species(Alakit) showed the most promising antimicrobial properties.Conclusions:It can be concluded that many of the tested plants have antibacterial activity and supports the traditional usage of the plants for mastitis,wound and gastrointestinal complications treatment.Further studies into their toxicity and phytochemistry is advocated. | Shewit Kalayou Mekonnen Haileselassie Gebremedhin Gebre-egziabher Tsegay Tiku'e Samson Sahle Habtamu Taddele Mussie Ghezu | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，7： | 3 |

| 4 | Food safety knowledge and practices of abattoir and butchery shops and the microbial profile of meat in Mekelle City,Ethiopia显示文摘Objective:To assess the food safety knowledge and practices in meat handling,and to determine microbial load and pathogenic organisms in meat at Mekelle city.Methods:A descriptive survey design was used to answer questions concerning the current status of food hygiene and sanitation practiced in the abattoir and butcher shops.Workers from the abattoir and butcher shops were interviewed through a structured questionnaire to assess their food safety knowledge.Bacterial load was assessed by serial dilution method and the major bacterial pathogens were isolated by using standard procedures.Results:15.1%of the abattoir workers had no health certificate and there was no hot water,sterilizer and cooling facility in the abattoir.11.3%of the butchers didn’t use protective clothes.There was a food safety knowledge gap within the abattoir and butcher shop workers.The mean values of bacterial load of abattoir meat,butcher shops and street meat sale was found to be 1.1×10~5,5.6×10~5and 4.3×10~6 cfu/g,respectively.The major bacterial pathogens isolated were Escherichia coli,Staphylococcus aureus and Bacillus cereus.Conclusions:The study revealed that there is a reasonable gap on food safely knowledge by abattoir and butcher shop workers.The microbial profile was also higher compared to standards set by World Health Organization.Due attention should be given by the government to improve the food safety knowledge and the quality standard of meat sold in the city. | Mekonnen Haileselassie Habtamu Taddele Kelali Adhana shewit Kalayou | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，5： | 1 |
| 5 | 巴西圣保罗州莫日—瓜苏河流流域中的汞:根据^(210)Pb测年剖面估计的沿海泻湖与河流贡献之间的联系显示文摘本文估计了莫日-瓜苏河水和悬浮泥沙样中和位于主河道采样点下游的其三个沿海泻湖(卡廷圭卢、巴里尼亚以及里奥佩德拉斯)的水体和河底泥沙中的总汞含量。结果发现,悬浮泥沙和河底泥沙中的汞浓度均较低。铝被用来作为校正里奥佩德拉斯泻湖沉积岩心中汞浓度的地球化学示踪物(r=0.92)。据估计,莫日-瓜苏河每年输送19kg汞,其中65%处于溶解状态,35%吸附在颗粒性物质上。在1970~1980年期间观察到的急性中毒时期之后,河流流域主要通过自然恢复和进入生态系的汞输入量普通降低,已恢复到其原来的状态。 | Glauco Arnold Tavares JoséRobertoFerreira CarlosEmanueldeCarvallhoMagalhāes Nivaldo Carlos de Silva Maria Helena Tirollo Taddel 林宝法 | 2003 | AMBIO-人类环境杂志2003，32，1： | 0 |
