Many plants have been screened for antimicrobial activity and drug properties. The aim of the present study encourages the use of spices as alternative or supplementary medicine to reduce the burden of high cost, side effects and progressively increasing drug resistance of pathogens. In present study methanol and chloroform extracts of Curcuma longa (fresh and dry) were prepared from the rhizome. The antimicrobial properties of both of the extract were studied by testing the antibacterial as well as antifungal activity. The antibacterial test was done by agar well diffusion method against bacterial species such as Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Protease vulgaris, Pseudomonas aeruginosa, Bacillus cereus, Bacillus megatarium, Bacillus subtilis and fungal species such as Aspergillus niger. The zone of inhibition of the extract were determined and compared with the standard drug streptomycin to know the efficiency. The methanol extract of rhizome was found to be more effective when compared with other solvent like chloroform. The phytochemical analysis of both of the extract revealed the presence of alkaloids, flavonoids, terpenoids, tannins, saponin and steroids.

In this experiment, we tried to explore the changes that are occurring in radish due to the treatment with copper. A pot culture experiment was conducted and copper was applied to radish (Raphanus sativus) plant. Macronutrients such as, nitrogen, phosphorus, potassium, sodium, calcium, magnesium were analysed for the treated plants. The results showed that the low concentrations of copper level (50 mg kg) enhanced the macronutrients while higher concentration of copper(100 250 mg kg) in the soil decreased these parameters.

The aims of this study are to investigate the effects of consumption of fatty acids, nutrients and application of vibration on bone histomorphometry and mechanical properties in addition to metabolic bone parameters in rat. Fifty six male Wistar rats were divided into seven independent groups and treated for 8 weeks as followings: (1) Control (received regular rat chaw food and drinking water); (2) RV (regular food + vibration); (3) SPM (regular food + vibration + calcium + vitamin D + boron); (4) CA (SPM + canola oil); (5) SU (SPM + sunflower oil); (6) CA + SU (SPM + Canola oil + Sunflower oil); and (7) CO (SPM + coconut oil). After 8 weeks, plasma samples were analyzed for vitamin D, parathyroid hormone, calcitonin, testosterone, free testosterone, and estrogen levels. The right femur bone was excised for histomorphometric and geometric analyses. The left femur and fifth lumbar vertebra were also used for evaluation of mechanical properties. Our results indicated that compact bone area and number of osteocytes in all treatment groups and energy to maximal load in RV compared to control group were significantly increased (P<0.05). The decline in trabecular separation area, femoral neck maximal load, and femoral neck stiffness in SPM compared to control, RV and both groups were significant (P<0.05). Also, several significant changes in spongy bone and trabecular separation areas, femoral neck maximal load and stiffness, lumbar maximal load and lumbar energy to maximal load between control and different treatment groups were detected (P<0.05). Decrease of trabecular separation area in CA, CA+SU, and CO groups compared to control group and femoral neck deformation in SU compared to CA group were significant. Finally, significant increase in estrogen level in CO group compared to all other groups was detected. Our findings demonstrated that combination of whole body vibration and coconut oil has beneficial effects on bone histomorphometry, mechanical properties and metabolic parameters.
本研究的目的是探讨脂肪酸、营养物质的消耗和振动对大鼠骨组织形态学和力学性能以及骨代谢参数的影响。将56只雄性Wistar大鼠分为7个独立组，按以下方法治疗8周:(1)对照组(给予常规大鼠咀嚼食物和饮水);(2) RV(正常食物+振动);(3) SPM(常规食物+振动+钙+维生素D +硼);(4) CA (SPM +菜籽油);(5) SU (SPM +葵花油);(6) CA + SU (SPM +菜籽油+葵花油);(7) CO (SPM +椰子油)。8周后，分析血浆样本的维生素D、甲状旁腺激素、降钙素、睾酮、游离睾酮和雌激素水平。切除右侧股骨进行组织形态学和几何分析。左股骨和第五腰椎也被用来评估机械性能。结果表明，与对照组相比，各治疗组大鼠骨致密面积、骨细胞数量和最大负荷能量均显著增加(P<0.05)。与对照组、RV组及两组相比，SPM组股骨小梁分离面积、股骨颈最大负荷、股骨颈刚度下降均有统计学意义(P<0.05)。对照组和不同治疗组的海绵骨和小梁分离面积、股骨颈最大负荷和刚度、腰椎最大负荷和腰椎能量对最大负荷的变化均有统计学意义(P<0.05)。CA组、CA+SU组和CO组股骨小梁分离面积较对照组减少，SU组股骨颈变形较CA组显著。最后，与其他各组相比，CO组雌激素水平显著升高。我们的研究结果表明，全身振动和椰子油的组合对骨组织形态学、力学性能和代谢参数有有益的影响。

The electromagnetic problem has been solved for randomly oriented nonspherical and inhomogeneous structures with complex refractive indices 1.33018–2:09 x 10i (immersed in water) due to the T -matrix method. The light scattering properties of spheroidal erythrocytes/leukocytes for each condition were obtained using so-called Mie theory. In this study, the spheroidal erythrocyte is assumed to have a radius of 2:78 mm; giving it a volume equivalent to the average actual erythrocyte, and is illuminated by a plane wave of l 1⁄4 873 nm: The T -matrix elements are obtained by numerical integration in each condition. Comparisons for erythrocytes/leukocytes with oxygenated hemoglobin and immersed in water, and its results for large, randomly oriented spheroids, show that the applicability range of the scattering process depends on the imaginary part of the refractive index and is changed for different elements of the scattering matrix.

Chlorine is the most common disinfectant used in drinking water that can reacts with naturally occurring organic matter to form a number of chemical byproducts as trihalomethanes (THMs). The aims of the present study are to investigate the levels of THMs in Aga surface water plant (ASWP) and its distribution system (DS)during the period between spring 2015 and winter 2016 as well as its levels in tanks in August 2015. Drinking water samples were collected from ASWP, in addition to4 sites away from the plant at different distances. Other parameters as temperature and residual chlorine were measured. The maximum concentrations of THMs in ASWP were detected during summer, 2015 while the minimum concentrations were recorded during autumn 2015. While in DS, the maximum value recorded atsite 4. Generally, all values of THMs during the study lies within the limits of the Egyptian standards 458 decreed in 2007.

The aims of the present study are to investigate the levels of THMs in Aga surface water plant (ASWP) and its distribution system (DS)during the period between spring 2015 and winter 2016 as well as its levels in tanks in August 2015. Drinking water samples were collected from ASWP, in addition to4 sites away from the plant at different distances. Other parameters as temperature and residual chlorine were measured. The maximum concentrations of THMs in ASWP were detected during summer, 2015 while the minimum concentrations were recorded during autumn 2015. While in DS, the maximum value recorded atsite 4. Generally, all values of THMs during the study lies within the limits of the Egyptian standards 458 decreed in 2007.","PeriodicalId":13830,"journal":{"name":"International Journal of Advanced Research in Biological Sciences","volume":"58 26 1","pages":"37-43"},"PeriodicalIF":0.0,"publicationDate":"2017-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90309260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
