The proximate composition and nutritional quality of two mushroom varieties cultivated in Egypt (Agaricus bisporus and pleurotus ostreatus) were investigated using standard analytical techniques. The samples of mushroom contained 26.05% and 33.85%, crude protein in the dried P. ostreatus and A. bisspours respectively. Crude fat content in mushroom varieties (P. ostreatus and A. bisporus) were almost the same (P > 0.05) and had value of 2.79% and 2.41%, respectively. Also, other proximate composition values were in the following ranges: moisture content 9.65%-11.81%, ash 5.86%-7.97%, crude fibre 8.25-13.21% and carbohydrate (by difference) 57.05%-42.56%. for (P.ostreatus and A.bisporus) respectively. Protein in both of dried mushroom varieties (P. ostreatus and A. bisporus) were slightly lower than FAO/WHO (1973) in total essential amino acids., the total essential amino acids values of dried mushroom (P.ostreatus and A.bisporus) were 39.25 and 44.95 gm / 16 gm N, respectively. The results show that histidine scored the highest chemical protein score of 140.38 and 136.15 for dried mushroom varieties Also, dried mushroom varieties Agaricus bisporus and Pleurotus ostreatus oils had higher amounts of unsaturated fatty acids. Total phenols and antioxidant activity in dried Agaricus bisporus were significantly (P < 0.05) higher than that in Pleurotus ostreatus. The results showed that these nutrient rich mushroom flours under investigation may prove useful in the formulation of different food products such as, retention of flavour and palatability.

This investigation was conducted during two successive seasons of 2004 and 2005 at the experimental farm of El-Quassassin Hort. Res. Station, Ismailia Governorate, Egypt, to study the effect of irrigation rates (1610, 3220 or 4876 m 3 /fed.) and fertilization treatments (NPK and organic fertilizers) on vegetative growth, volatile oil yield and chemical composition of Majorana hortensis L. plant in sandy soil. Application of the high rate of water irrigation (4876 m 3 /fed./season) gave the highest values of vegetative characteristic i.e., plant height, fresh and dry weight of herb/plant, dry weight of leaves and stems/plant, the yield of fresh and dry weight of herb per plant and per feddan and chemical composition i.e., volatile oil percentage and N, P or K content as compared with 1610 or 3220 m 3 /fed./season water amount irrigation in the three cuttings during the two seasons. Application NPK fertilization treatment (300 , 300 , 100 kg/fed. as ammonium sulphate, calcium superphosphate and potassium sulphate, respectively) surpassed significantly in vegetative characteristics, oil percentage and chemical content when compared with organic fertilization (compost, poultry and cattle manure). On the other side, poultry manure (10 m 3 /fed) gave significant increase in the most characteristics under this study when compared to the compost or cattle manure (15 and 20 m 3 /fed. respectively) fertilization treatments. Irrigation sweet marjoram plants with drip irrigation system at water amount of 4876 m 3 /fed./season gave 14.305 and 4.688 ton per feddan fresh and dry weight of herb, respectively and 2.63 % (dry weight) volatile oil percentage. The maximum contents of Terpinene-4-Ol and Linalool were obtained from the high level of irrigation (4876 m 3 /fed/season) combined with cattle manure fertilization treatment. While the high contents of 1,8 Cineole and Limonene were resulted from the high level of irrigation combined with poultry manure fertilization treatment.

Helicobacter pylori is a gram negative bacterium and considered as one of the causative factors of gastritis and peptic ulceration. The exact route of transmission is still unknown. H. pylori infection was highly prevalent worldwide. Objectives: to detect H. pylori infection rate by different tests including ELIZA tests for anti H. pylori antibodies (IgM, IgG, IgA) and H. pylori antigen, to isolate H. pylori by bacterial culture, to evaluate antimicrobial susceptibility of bacteria and to estimate bacterial infection rate according to clinical symptoms of patients. Methodology: This study was done on 130 stool samples and 130 blood samples collected from 130 patients attending Gastroenterology Department of Assiut University Hospital and some special medical laboratories, collected during the period from March 2019 to February 2020. Stool samples were processed to detect H. pylori antigen titers and to isolate H. pylori bacteria, blood samples were processed to detect anti H. pylori antibodies. Antimicrobial susceptibility of H. pylori was evaluated to ten antibiotics by disc diffusion method. Results: H. pylori infection rate was 86.1% by bacterial culture, 81.5% by anti-H. pylori IgG antibodies test , 48.5% by anti-H. pylori IgA antibodies test, 13.8% by anti-H. pylori IgM antibodies test, 76.9% by H. pylori antigen test. 39.2% of H. pylori infected patients had abdominal pain. Bacterial strains were resistant to several antibiotics. Conclusion: we concluded that anti-H. pylori IgG antibodies and H. pylori antigen tests were the preferable tests for diagnosis of H. pylori infection. According to statistical analysis, these results were more reliable and valuable. Abdominal pain was the most common symptom in H. Pylori infection. ciperofloxacin and amoxicillin were the most effective antibiotics for inhibition of bacteria.

The present work was carried out during the two successive seasons of 2010 and 2011 in the shade house of the Viticulture Department, Horticulture Research Institute, in Giza, Agric. Res. Center, Ministry of Agriculture. The used cuttings were taken from mother Dogridge vines grown in the private farm at 58 Km Cairo -Alex. desert road. Hard-wood cuttings were taken in Jan. from moderately vigorous 1-year-old canes, each cutting comprised three nodes (eyes) and was about 30-35 cm long. The cuttings were stored with their basis upwards in the shade house until planting on 15 Feb. in both seasons Henna extracts obtained from the crushed dried leaves of Lawsonia inermis L. 200 gm Henna was immerged in one liter for 48 hours in one of the following solvents:tap water, boiled water, ethyl alcohol, hexane, acetone and petroleum ether. The used concentration from henna crude extracts by different solvents was 3gm/ l of distilled water (i.e.3000 ppm). Cuttings were soaked in each of the considered extracts for 24 hours before planting. In addition, the recommended application of the growth regulator IBA at (1000 ppm) by dipping for 10 seconds was used as a control. The best results were obtained by henna extracted by acetone and tap water solvent without significant differences among them. While, untreated cuttings gave the lowest results followed by cuttings treated by ethyl alcohol extract and than IBA treatment. The other henna extractions were ranged between them. Generally, it is possible to improve rootapility of Dogridge grape rootstock cuttings by soaking cutting basis in henna extracted by acetone or tap water solvents which gave nearly similar effect, but use of tap water solvent, is more economic and easier for application.

The present investigation was conducted in season (2006-2007) to study the best harvesting method , the best drying method, packages type and storage period in peppermint which give the lowest average of total microbial count (TMC) and best essential oil content with active ingredients of the oil. The results of this study indicated that the best harvesting method occurred with using gloves with clear plastic, harvesting boxes; while, the best drying system was the solar drying. The best package type through storage period was carton boxes; increasing storage period decreased the volatile oil percentage and the most of main components.
