Blood samples were taken one week before Ramadan then after 10 and 25 days of fasting in Ramadan and one week after the fasting. The blood samples were analyzed for fasting blood sugar FBS (glucose), plasma triglycerides (TG), total cholesterol (TC) , low and high-density lipoprotein (LDL-C and HDL-C), urea and uric acid. Results show that blood glucose, total cholesterol, LDL-c, urea and uric acid in both men and women were significantly (P
Abstract: The subject of economic reform has been recently placed at the top of programmers of economic policies in developing countries. The reform process can not be integrated reform without the other sectors, including the agriculture one. The aim of this research demonstrates the impact of economic reform on the amount and efficiency of agricultural loans provided by banks for farmers, especially small farmers. The hypothesis of research refers to the affects of economic reform on the amount and efficiency of loans provided by agricultural banks in the sample (Syria, Egypt, and Saudi Arabia). And was relying on two-way link in analysis, the first is based on theoretical studies which addressed the same subject, the second, quantitative methods based, on econometric, and then interpret the results of the quantitative method for assessing the theoretical side in the study. The analysis depended on the post-reform economic periods. Efficiency of agricultural Lending measuring by contributing of agricultural loans in the agricultural production for countries in the sample. Conclusions show that there are positive indications in some changes after adopting the economic reform on the research sample, and confirms that the adoption of economic reform programmers could be used in agricultural banks.
Abstract: The goal of this study was to use plant tissue culture technique in vegetative propagation of Gardenia (Gardenia jasminoides) by using single nodes and shoot tips excised from soft cuttings and treated with different concentrations of growth regulators. The results revealed that the use of different disinfistants was highly effective in reducing cultures contamination. The use of mercuric chloride (0.1%, HgCl2) for 10 minutes was very effective in preventing contamination and gave the highest survival percentage (99%). Results at initiation stage revealed that the culture of single nodes of Gardenia on a medium containing 3 mgl-1 BA+ 0.9 mgl-1 IAA gave the best growth response in which highest number of shoots and leaves. At vegetative multiplication stage, the results showed that the medium supplemented by 1.5 and 4.5 mgl-1 BA+ 0.6 mgl-1 IAA gave the highest value of growth length and gave the highest number of shoots per explant. In order to promote the shoots produced at vegetative multiplication stage to root, it was noticed that the treatment of 4 mgl-1 NAA and8 mgl-1 IAA gave the highest percentage of rooting and values of the number and length of roots. Plantlets obtained were transferred to pots and acclimatized with 95 % success.

Abstract: Fifteen local breed male rabbits 8 weeks aged were allocated into three groups. In order to study the effect of using Nigella Sativa seeds in their rations on productive performance, carcass traits and digestibility. The first group was fed standard ration according to (NRC, 1994), containing 15.6% crude protein 2243 kcal/kg. ME, and 10% soybean meal (SBM), while the second and third groups were fed the same ration with exception of partial replacement of (SBM) in a ratio of 2 and 4% by Nigella Sativa L. seeds (NSS), respectively. The feeding trial lasted for eight weeks, the amounts of ratio consumed and weight gained were determined weekly. At the last week of feeding period all feces produced from each group were collected, then all rabbits were slaughtered and carcass measurements were taken. There were no statistical differences among the groups in the average of final wt. and total wt. gain, the feeding conversion ratio was improved at 22% for the groups which were fed rations with NSS when compared with the group fed standard ration. However there were no statistical differences amongst all groups concerning carcass measurements. The results indicated an improvement in the dry matter and the other nutrients digestibility for rabbits consuming ration containing NSS. In conclusion the addition of NSS at 4% in the ration of local rabbits improve the values of productive parameters, carcass traits and nutrients digestibility.

Abstract: Processed cheese was manufacture from whole sheep milk. The first treatment was conducted by mixing full cream sheep milk cheese with low fat cow curd cheese; in other treatment a low fat labnah (semidried yoghurt) was used to produce three levels of low, medium and high fat cheese (20,30 and 40% ±1)respectively, calculated on dry matter base. Three types of emulsifiers were used for each fat level. From chemical analysis the curd and labnah used had decreased fat percent because they contain less fat. Chemical contain of cheese where inversely increased with fat percent. Physical properties of the processed cheese were improved concerning dispersion, penetration and cutting time, Whoever the least improvement was observed in low fat cheese stored at refrigeration for a longer storage time when using sodium citrate as emulsifier which gave the sample more higher. Cheese samples were organoleptically evaluated and the best sample was the high fat cheese stored in refrigerator for one day. Results also indicated that using low fat labnah as filling matter was preferable compering to curd in both physical and organoleptical properties.
Abstract: The present study was carried out to investigate the effect of fertilization levels, years of adding fertilizers, and age of growth rings on the percentages of the chemical components of young Pinus brutia Ten. Trees grown in Nineveh forest. Analysis of variance shows that all factors with their interactions have significantly affected all the chemical components except the factor of the years of adding fertilizer as there has no significant effect on the percentages of extracts and the interaction of the years of adding fertilizer and fertilizing levels as there has been no effect on the percentages of extracts in ethanol-benzene. Fertilizing treatments have generally shown not clear trend in the increase percentages of ethanol-benzene extracts, while a significant increase in holocellulose and ash percentages were noticed. The increase in the levels of fertilizing treatments has led to a decrease in the percentages of lignin and hot-water extracts compared with samples that have not received fertilizer. The fertilizing treatment (70 gm. Compound fertilizer, 750 ppm. Iron and 45 ppm. Zinc) compared with the non-fertilized trees have given the highest ratios of increase in the percentages of holocellulose as it has reached (11.21 %), and (72.22 %) for the ash, and the highest ratio of decrease in the percentage of lignin (26.36). It has been evident that providing fertilizer for two successive years (the fourth and fifth years of age) has led to a higher increase in the percentages of holocellulose and ash and a highest decrease in lignin compared to the addition for one year (fourth year). It is found that the fertilizing treatment (70 gm compound fertilizer, 750 ppm iron, and 30 ppm. Zinc) provided for two successive years have more effecting decreasing the percentage of lignin. The highest increase in the holocellulose obtained from the interaction effect of (70 gm compound fertilizer, 750 ppm. Iron, and 30 ppm. Zinc) provided for one year, while the same treatment provided for two successive years has led to an increase in ash content. According to the results obtained, we can state that the ratios of the studied components are still within the ranges that are industrially acceptable, so these woods although fertilized are useful to be used in the wood industries, especially in paper, fiberboards, and particleboards.
Abstract: This Study has been conducted to determine the most crucial of pollution and evaluate the percentage portions of these sources out of the whole sewage water in Aleppo city. the chemical characteristics of raw domestic sewage water and the amount of sewage water that goes in to the total run water in some different areas in Aleppo (low, medium, and high income areas).had been studied.For the( pH, NH4, TDS, BOD5, COD), all values are down allowable concentration based Syrian Standards 2850 for 2002. For the low income areas, an excess of TSS values during morning hours. While an excess of PO4 values and those of olis and lubrication have been noticed during different day hours except for the noon time, and an excess of ABS values at dawn and midnights times. For medium in come areas, there has been an excess in the values of PO4during the different day hours, an excess in the values of oils and lubrications at morning, noon. and night hours. and an excess of ABS values only at midnights. For high in come areas. an excess of TSS values were noticed at noon, an excess of oils and lubrication values at different time except for nights, and an excess of PO4 values at all times and an excess of ABS values at dawn and midnights compared with the allowable concentration based Syrian Standards 2850 for 2002. Based on the initial evaluation, the amount of domestic and industrial sewage water is estimatedat 480000 m3/day. Out of this amount about 455500 m3/day that is 94.9% comes form domestic consumption, and 24500 m3/day (5.1%) is industrial sewage.
Abstract: In this work Bioassay technique had used to identify the allelopathic potential effects of different parts of Johnson grass on the germination and seedlings growth of bread and durum Wheat, 2-row and 6-row Barley, Chickpea and Lentil. The results showed different inhibition of allelopathic potential for the residues in comparing with the control treatments for all six crops. The root extracts had the highest inhibition impacts on all of the characteristics studied, and less effect of both shoots and seeds. While the effect of seed extracts had the same effect or as control in most cases. The radical length and dry weight affected more than germination percentage, shoot length and shoot dry weight. The results also indicated that Lentil was more affected than 2-row Barley, bread Wheat, 6-row Barely and durum wheat, while the Chickpea had the lowest response.
