المستخلص Aspergillus fumigatusالتاثيرات المرضية المناعية للعدوى بفطر فطريات الاسبيروجلس من الفطريات الانتهازية واسعة الانتشار و من أكثر مسببات الأمراض ألغازيه الشرسة للأفراد الذي يعانون من نقص المناعة ( مثل زراعة الأعضاء والإصابة بفيروس نقص المناعة المكتسب في مراحله الأخيرة ).يعتمد الأشخاص الأصحاء على المناعة ألطبيعيه ألفطريه في القضاء على العدوة ,حيث تقوم الخلايا البلعمية بالقضاء على الابواغ الفطرية , بينما تقوم كرات الدم البيضاء المتعادلة بالقضاء على الهيفات بفعالية , وفي حالة حدوث خلل في كفاءة هذه الخلايا فان فطر الفيومجاتس سوف يسبب في حدوت عدة أمراض منها داء الرشاشات ,التهاب رئوي تحسسي و داء الرشاشيات الرئوي ألغازيه. الكلمات المفتاحية: فطريات الاسبيروجلس فيومجاتس , داء الرشاشات ,التهاب رئوي تحسسي, نقص المناعة, زراعة الاعضاء Abstract :. Aspergillus fumigatus is a ubiquitous mold that causes invasive disease in immunocompromised patients.( as organ transplantation and late-stage human immunodeficiency virus infection).while healthy people depend of the innate immune responses control infection. Conidia are phagocytosed by alveolar macrophages, while neutrophils are rapidly recruited to the lungs and effectively kill hyphae.however, In the absence of effective macrophage and/or neutrophil functions,might occurs several form of diseases caused by A. fumigatus, including saprophytic colonization (aspergilloma), hypersensitivity pneumonitis and necrotizing pneumonia with angioinvasion (invasive pulmonary aspergillosis) Key woreds Aspergillus fumigates , invasive disease, aspergilloma, hypersensitivity pneumonitis, invasive pulmonary aspergillosis, immunocompromised, organ transplantation.

(Extraction palm kernel oil from palm kernel using super-critical carbon dioxide(SC-CO2

Extraction of palm kernel oil(PKO) from dehulled ground palm kernel using supercritical carbon dioxide (SC-CO2) was studied at conditions of 313.2 and 353.2 K and at pressures from 20.7 to 48.3 MPa. The yield of PKO increased with pressure from 34.5 to 48.3 MPa at353.2K and attained a value of 49 g oil/100 g palm kernel at 48.3 MPa and 353.2 K

Nitric oxide (NO) produced by inducible nitricoxide synthase (iNOS) within the central nervous system (CNS)mainly exerts adverse effects in neuroinflammation. Experimentalautoimmune encephalomyelitis (EAE), an animal model of multiplesclerosis, is a neuroinflammatory disorder. CXCL12 is a chemokine,whose antiinflammatory role in EAE has been described recently. Itsmajor producers in the CNS are astrocytes and endothelial cells ofmicro blood vessels (MBV). The aim of this work was to investigate invitro and in vivo effects of NO on CXCL12 gene expression in ratastrocytes and MBV.Materials and methods: Spinal cords (SC) were isolated from rats thatdeveloped EAE at different stages of the disease, homogenized andassessed for iNOS and CXCL12 gene expression by ‘real time’ RT-PCR.In vitro studies were performed on MBV isolated from SC of healthy,non-immunized adult rats, astrocytes derived from neonatal rats andC6 cells (rat astroglioma). After stimulation with supernatantscollected from splenocyte cultures stimulated with concanavalin Afor 48 h or with combination of cytokines (IL-1b + TNF + IFN-c + IL-17) they were exposed to NO donor, sodium-nitroprusside(SNP). Also, peritoneal cells isolated from healthy rats were co-cultivated with astrocytes. Nitrite accumulation in supernatants, asindirecte measure of NO release, was determined using Griess reactionand CXCL12 gene expression was measured by PCR. In vivo, ratsimmunized to develop EAE were treated with aminoguanidine, aninhibitor of iNOS activity, starting from day 9 post immunization,once per day until the disease peak was reached in control, untreatedgroup. At this point, CXCL12 gene expression was determined in SChomogenates and MBV.Results: We found negative correlation between gene expression ofiNOS and CXCL12 in SC of EAE rats. NO released from SNP orproduced by peritoneal cells in vitro significantly reduced CXCL12gene expression in astrocytes and MBV. In vivo inhibition of iNOS ledto upregulation of CXCL12 gene expression and reduction of EAEseverity in rats.Conclusions: These results imply that NO is important inhibitor ofCXCL12 expression within the CNS during the encephalitogenicautoimmune response. This adds to the list of harming effects of excessgeneration of NO in neuroinflammation
