Abstract In Fayoum Governorate, Egypt, the influence of tillage on the soil fauna was studied. For this reason, two plots (the first and the third) were not tilled, and were cultivated with various crops (tomatoes and different crop residues). The second study plot consisted of fallow land and was ploughed and cultivated with tomato with conventional tillage practices. Data of activity density of the soil fauna taxa were treated by multivariate statistical methods: correspondence analysis and ascending hierarchic classification. Comparisons indicated that higher activity densities of the herbivorous soil fauna taxa were generally associated with no-tillage practices. After the incorporation of the live green Lupinus termis and Trifolium alexandrinum in the soil, activity densities of some groups of soil fauna taxa increased such as Collembola and Orthoptera. Carnivorous soil fauna also increased after ploughing soils. Agricultural practices that adversely affect activity density as well as diversity of so...

The best way to prevent Fascioliasis is through the reduction in population of the Lymnaeid snail intermediary host. Plant based molluscides had over the years shown remarkable promises. Presented here are a series of experiments evaluating the potency of crude seed oil extracts of Azadirachta indica, Acacia albida and Balanite aegyptiaca against Lymnae natalensis, an intermediary host of Fasciola gigantica collected from Katagum Local Government Area of Bauchi State, Northeastern Nigeria. The results indicated that, molluscicidal potency of seed oils of A. indica, A. albida and B. aegyptiaca were concentration dependent. Mortality rate increases with corresponding increase in concentration of the extracts. Comparatively, seed oil extracts of B. aegyptiaca showed higher molluscicidal tendencies, followed by A. indica and lower with A. albida. The results of the LC50 and LC90 values of different seed oils on Lymnae natalensis varied accordingly. All the three plant species seed oils ...

Sweet potato flour and Camel milk can serve, as a source of some nutrients, natural sweetness, colors and flavor, to prepare food product formulas. Both of them, alone or together, could be considered as an excellent novel source of natural health-promoting compounds in the functional food market. Sweet potato flour contains plenty amounts of βcarotene and anthocyanins, while, camel milk is a very important food stuff, due to its low cholesterol, low sugar, high minerals and vitamin C contents. The physico-chemical and sensory properties of cakes containing different concentrations of the tested sweet potato powder and camel milk as a partial replacement of wheat flour were estimated. The present results showed that, total phenolic compounds and antioxidant activity were increased by increasing the potato powder in the cake. The cake height and volume were decreased, compared with the control sample. The tested cake showed no significant differences in terms of odor, texture and ove...

Various ecological studies report a reduction in cardiovascular disease mortality risk with increasing magnesium levels in drinking water. Most of the studies done in this field were epidemiologic studies.The aim of the present study was to examine whether magnesium addition to drinking water can affect risks of cardiac disease. The study included five groups of male albino rats. The rats received either tap water or water containing 5, 10, 20 g of magnesium sulfate per liter. During the whole experiment, all the groups received hypercholesterolemic diet except for the normal control which received normal basal diet. At the end of the experiment, blood was drawn for the determination of plasma magnesium, lipid profile and liver function. In addition, the extent of obesity was determined using the body mass index (BMI). In all groups magnesium addition was associated with higher levels of plasma magnesium. The blood analysis showed a significant decrease in serum total cholesterol, t...
