Two field experiments were carried out during growing seasons 2010 and 2011, it executed in research farm of national research center in Nubaryia region, Egypt to study the effect of pulse drip irrigation and mulching systems for saving water, increasing and improving yield of soybean. The study factors were, pulse drip irrigation technology (adding of daily water requirements on 4 times, 8 times, 12 times compared with adding of daily water requirements on 1 time) and mulching systems (covering the soil with black plastic mulch “BPM”, rice straw mulch “RSM” and the control treatment was soil surface without mulch “WM”). The following parameters were studied to evaluate the effect of pulse drip irrigation and mulching systems: 1) Soil moisture distribution in root zone, 2) Growth characters of soybean plant, 3) Yield of soybean, 4) Irrigation water use efficiency of soybean “IWUE soybean”, and 5) Oil content and oil yield, 6) Protein content and protein yield, 7) Economical parameter. According to the economical view and the results of statistical analysis for effect of pulse drip irrigation and mulching systems on yield, quality traits and IWUE soybean indicated that, applying the irrigation requirements on 8 pulses/day with using BPM is the best conditions because under these conditions was occurred the highest value of yield, quality traits and IWUE soybean and there was significant deference between this case and other treatments. Where, pulse irrigation technique increase from water movement in horizontal direction than vertical direction hence improve from soil moisture distribution and wetted soil volume in root zone and using BPM decrease from evaporation process rate from soil surface hence decreasing of salts accumulation in addition to decreasing of weed growth in the root zone. All traits at AIR on 12 pulses/ day are decreased by increasing of pulses, this may be due to irrigation water was very small with every pulse at AIR on 12 pulses/day in addition

In order to mitigate the salinity effects on flax grown on moderate saline sandy soil (3275 - 3430 ppm) and irrigated with moderate saline water (2300 - 2460 ppm) field experiments were carried out at the experimental Station of the Faculty of Agriculture, Wadi El-Natrun district El-Behera Governorate—Egypt, during two successive winter seasons of 2012/2013 and 2013/2014. Three flax varieties (Opal, Giza-8 and Mayic) were grown and treated with some chemical additives humic acid (50 kg/fed) and/or foliar applied proline (Control, 50 and 100 mg/L). The results showed the positive responses of Giza-8 variety to the combined application of humic acid and proline and mitigated the salinity effects of soil and irrigation water and reflected on most of the studied characters. Such results indicate the potentiality of mitigation the hazardous effect of salinity with these chemical additives. The data indicated that the highest seed yield, straw yield and oil yield were obtained at humic acid (50 kg/fed) with foliar treatment of proline at rate of (100 mg/L). The interaction of proline at (100 mg/L) with humic acid at rate of (50 kg/fed) improved plant fresh and dry weight in all flax cultivars under salinity conditions. Fresh weight increased by 66.6%, 48.7% and 65.5% over controls for Opal, Giza-8 and Mayic varieties, respectively. The interaction of proline at (100 mg/L) with humic acid at rate of (50 kg/fed) with Giza-8 variety gave the highest values of seed yield, straw yield and oil yield.

本论文采用中链甘油三酯(MCT)和长链甘油三酯(LCTs,棕榈,大豆和菜籽油)为乳液油相,研究了高场强超声乳化对含有不同油相的大豆分离蛋白(SPI)稳定乳液理化性质的影响。此外,研究了高场强超声乳化对不同离子强度(0,25,50,100,200,300m M)条件下的菜籽油-大豆蛋白乳液理化性质的影响。结果表明,在超声乳化18分钟后,MCT乳液的d值达到0.5±0.0μm,液滴尺寸最小。相比于LCT乳液,MCT乳液具有更好的乳液稳定性(中性p H及室温下条件下采用蒸馏水作为水相),界面吸附蛋白量更高,但其ζ-电位值最低。特别的是,棕榈油乳液在90℃热处理30分钟后粒径减小。在中性p H和室温下,低盐浓度(100 m M Na Cl)的SPI稳定乳液在冻融循环后具有更高的稳定性。在超声乳化前向SPI溶液中加入Na Cl,乳液的界面吸附蛋白量显着增加。高场强超声波技术是一种有效的乳化手段,可用于制备大豆分离蛋白稳定乳液。此外,在不同油相种类、离子强度以及超声时间条件下,高场强超声乳化制备的大豆分离蛋白稳定乳液具有不同的物理化学性质。

Lumbar disc herniation is a common complaint among adults with degenerated lumbar intervertebral discs, however its incidence in childhood and adolescence is abundant. Findings recommended that pediatric lumbar disc herniation is dissimilar in numerous way from that in adults. It was confirmed that pediatric patients respond to conventional management less than adults, also the consequence of the operation continued to be acceptable for at least 10 years after the first surgery even though it seems to decline somewhat. This retrospective study was undertaken to determine the clinical outcome and the feature of lumbar disc prolapse in pediatric patients. 12 patients younger than 18 years were operated for lumbar disc prolapse in the period from 2012-2016. Patients preoperative data and radiological imaging, operative and postoperative follow up were reviewed. 12 patients were included in this study, 10 were male and 2 females, the average age was 15 years (ranging between 12 - 18 years). The average duration of the symptoms was 11 months. The average follow up was 14 months. All patients had a sciatica prior to surgery, 35% had motor deficit, and 60% had parasthesia. Conservative treatment failed in all patients. After surgery and follow up, improvement occurs in about 80% of patients, ranging from excellent to good, and 20% of patients with fair outcome. According to Pain Visual Analogue Scale, leg pain reduced from 90 - 30 and back pain from 80 - 35. Conclusion: Pediatric lumbar disc herniation is an uncommon object leading to hospitalization. About 0.1% - 0.2% of children and adolescence surgery for lumbar disc herniation in pediatric does not lead to chronic back pain or interfere with physical activity and is related to the excellent short consequence.

Background: Toxoplasma gondii (T. gondii) is an intracellular parasite mainly found in the central nervous system CNS, however, it can persist in multiple tissues in the body. Moreover, T. gondii is the commonest protozoans causing infections among individuals with acquired immunodeficiency syndrome (AIDS). Thus, the aim of this study was to investigate the frequency of T. gondii infection among AIDS patients in Makkah at Saudi Arabia. Methods: Fifty patients with AIDS proved to be positive by ULTRA HIV Ag-Ab Enzyme Immunoassay, and thirty healthy volunteers negative for AIDS by ULTRA HIV Ag-Ab Enzyme Immunoassay were subjected to determination of anti T. gondii immunoglobulin M (IgM) antibody seropositivity and anti T. gondii immunoglobulin G (IgG) antibody seropositivity using commercially available enzyme-linked immunosorbent assay kits. Results: The results showed that the seropositivity rate of anti T. gondii IgM antibodies among AIDS patients (18%) was significantly higher than in the healthy volunteers group (3.33%). Regarding the serum level of anti T. gondii IgG antibodies among AIDS patients, it was 30% significantly higher compared with those of the seropositive healthy volunteers (6.67%). Conclusions: These statistically significant results support the association between T. gondii infection and AIDS and suggest the usefulness of providing data for an educational program that will be designed to prevent T. gondii infection among AIDS patients.

In the current study, hydatid cysts from livers and lungs of camels were obtained from Tambool slaughter house and protoscoleces were separated aseptically. 36-weeks-old Swiss mice (25 - 30 gram body weight males and females) were divided into two groups of 6 each: a prophylactic group dosed with 150 ml/kg of albendazole and mebendazole was given directly after injection with 2000 protoscoleces intraperitoneally for 10 consecutive days. The treated group was given a dose of 300 ml/kg of albendazole and mebendazole for 24 days with 4 days interval separated by 2 days and after 6 months of inoculation with protoscoleces, the two groups in addition to the control group were sacrificed and necropsied. The results revealed a significant difference in the development of hydatid cyst (p < 0.01). Inside the mice, small number of cysts was noticed in the group treated with albendazole and mebendazole compared to the control group, however, albendazole was highly efficacious than the mebendazole where the efficiency of albendazole reached 97% while the mebendazole efficiency rate was almost 50% which indicates that albendazole could be considered the drug of choice in the treatment of hydatid cyst.
