Objective: To assess the general perspective of population their believes and myths regarding the pandemic outbreak and use of mask as precautionary measures Methods: A Cross-sectional observational study conducted from January-June 2020, among the general population of Karachi Total 470 participant age range of 18-60 years were included in the study Data was analyzed by SPSS version 21 0, for descriptive statistics Correlation between variables was assess by Kruskal Wallis Test, spearman rank correlation was established to assess the significant correlation between Knowledge, myths and practices Result: Out of 470 respondents, 74 31% were male and 25 69% of female More than half of respondents aged between 51 to 70 years i e 53 92% While 21 76% respondents were categorized in illiterate category The mean rank score for knowledge, myths and practices were 217 95±2 1, myths score was 236 07±2 1, 241 12±2 1 respectively The spearman rank correlation was established between knowledge myths and practices, a significant correlation between was established by Knowledge-myths (r= 0 0176, p= 0 015), knowledge-practices (r= 0 0174, p= 0 001) however myths-practices (r= 0 0170, p< 0 001) Believes and myths related to the mask was concerned i e 56 1 were using N-95 masks, 89% respondents reused the masks, 59 1% used the mask between 2 to 5 times Wearing mask is not a precautionary measure was mainly found as a myth in respondents i e 78 7% 67 2% respondents had myths about unnecessary use of mask The study highlighted the non-optimal behavior and practice with regards to the use of preventive measure including the use of mask in the pandemic outbreak © 2020 Assiut University All rights reserved
目的:评估人群对流感大流行爆发和使用口罩作为预防措施的总体看法、看法和误解。本研究于2020年1 -6月在卡拉奇市普通人群中进行横断面观察性研究,共纳入470名年龄在18-60岁之间的参与者。数据采用SPSS 21版进行分析,描述性统计采用Kruskal Wallis检验评估变量之间的相关性,建立spearman秩相关来评估知识、神话和实践之间的显著相关性。470名受访者,74 31%是男性和25 69%的女性超过一半的受访者年龄在51岁到70岁我e 53 92%,而21 76%受访者分为文盲类别对知识平均得分排名,神话和实践是217 95±2神话得分是236 07±2 1,241 12±2 1分别成立了斯皮尔曼等级相关知识神话和实践之间的显著相关性建立了Knowledge-myths (r = 0 0176, p = 0 015),知识-实践(r= 0 0174, p= 0 001),而神话-实践(r= 0 0170, p< 0 001)与口罩相关的信仰和神话受到关注,其中56.1人使用N-95口罩,89%的受访者重复使用口罩;59.1%的受访者使用口罩2至5次,佩戴口罩不是一种预防措施,其中78.7%的受访者对不必要使用口罩有误解,67.2%的受访者对不必要使用口罩有误解。该研究强调了在大流行爆发期间使用包括口罩在内的预防措施方面的非最佳行为和做法©2020 Assiut University版权所有

Ferula hermonis Boiss (Apiaceae) is known in the Midleast as 'zallouh'. In the last decade, scientists paid attention to study chemistry and biological activity of the plant. In this study Ferula hermonis were collected and evaluated for cytotoxic activity. The plant was extracted using different polarity solvents: petroleum ether, ethyl acetate and methanol. The cytotoxic effect of the extracts was examined in-vitro on human cell line (stomach cancer cell line, SCL-40). The assay was based on incubation of tetrazolium dye (MTT; a yellow water-soluble tetrazolium dye that is reduced by live, but not dead cells) with the cells that pre-incubated with a tested substance. A purple formazan product that produced can be determined spectrophotometrically. The result confirmed that the SCL-40 cells were much more sensitive to the petroleum extract than other extracts, which showed the prominent cytotoxicity. The plant showed pronounced cytotoxic activity will be further evaluated for the possible isolation of active antitumour compounds.
阿魏(阿蜂科)在中部至少被称为“zallouh”。近十年来,科学家们开始重视对这种植物的化学和生物活性的研究。本研究收集了阿魏,并对其细胞毒活性进行了评价。采用不同极性溶剂:石油醚、乙酸乙酯和甲醇进行提取。体外研究了提取物对人胃癌细胞株SCL-40的细胞毒作用。该方法采用四氮唑染料(MTT);一种黄色的水溶性四氮唑染料,可被活细胞(而非死细胞)与被试物质预先孵育的细胞还原。用分光光度法测定了所制备的紫色甲醛产物。结果证实,SCL-40细胞对石油提取物的敏感性明显高于其他提取物,显示出明显的细胞毒性。该植物显示出明显的细胞毒活性,将进一步评估是否可能分离出有效的抗肿瘤化合物。
