الهدف من هذا البحث هو معرفة دور الفيتامينات E و C في تطور مرض التهاب المفاصـل التنكسي أو التخفيف من شدته. تم قياس تركيز هذه الفيتامينات في مصل أشخاص طبيعيين و أشخاص مصابين بالتهاب المفاصل التنكسي، حيث تم إعطاء جميع المصابين جرعة فموية من المغنزيوم 10 ملغ / كغ / يوم لمدة أسبوعين ثم أعيد قياس تراكيز هذه الفيتامينات فـي المصل كما تم تقسيم المرضى المصابين بالتهاب المفاصل التنكسي إلى مجموعـات حـسب شدة المرض.
Serum levels of vitamins E and C were measured in 15 patients with Osteoarthritis ( OA ) and those patients received Magnesium 10mg /kg /day for two weeks ,and 15 healthy subjects as a control group Patients were classified into subgroups ,those with OA according to disease activity and /or sevirety .

This study was investigated at the laboratories of Horticultural department,
Faculty of Agriculture, Damascus University to measure the changes in
oxidative and antioxidative parameters during tomato fruit growth. Hydrogen
peroxide (H2O2) and lipi
d peroxidation (MDA) contents were analysed as
indicators of oxidative processes. Results showed that H2O2 content decreased
during fruit growth phase and slightly increased during ripening, meanwhile
MDA content was found to increase only at the end of fruit ripening. The
activities of antioxidant enzymes (SOD, APX, CAT) were modified during fruit
growth. Activities of SOD, APX increased during fruit growth phase,
meanwhile CAT activity increased during fruit maturation. The level of
ascorbate increased during fruit growth. These changes in antioxidant
metabolites and enzymes establish that the antioxidant system plays an
important role in the both phases of tomato fruit growth.
Functional foods are similar to conventional food and demonstrate beneficial effects
beyond their nutritional value. These effects are attributed to the presence of functional
ingredients. Functional ingredients can either be found naturally in a c
ertain food or added
to it. There’s a number of functional food products available in the market. For example,
natural functional juices containing polyphenols. The aim of this study is to determine total
phenolic content and antioxidant activity in some local functional juices. Total phenolic
content was determined according to Folin- Ciocalteu method. The highest in content was
mulberry juice, while the lowest was red grape juice. The best conditions for eliminating
ascorbic acid were also determined which were heating for
30 min at 75°C. Antioxidant activity was subsequently determined using potassium
ferricyanide. The highest in phenolic content among the studied juices were the highest in
antioxidant activity. Thus a strong correlation was found between total phenolic content
and antioxidant activity.
The aim of this study was to determine the
phenolic content in the fruit, leaf and root samples of the fennel
plant and in the fruit samples from several different areas, and
then to determine the antioxidant capacity of these samples.
Some local natural sources of antioxidant such as orange peel extract (Citrus
sinensis), pomegranate peel extract (Punica granatum) and ginger extract
(Zingiber officinale L.) were evaluated during 5 days storage of refined palm oil
at 63°C as com
pared to the synthetic antioxidant such as propyl gallate. The
above extracts were obtained with ethanol and oil (palm oil). Those extracts
were added to the oil at two different levels (100 ppm and 200 ppm).
Antioxidant activity of natural extracts, synthetic antioxidant and the control
treatment without antioxidant under thermal treatment (Schaal test) was
assessed by measuring acid value (AV), peroxide value (PV), iodine value (IV)
and refractive index (RI) during 6 days storage of refined palm oil at
temperature mentioned above. Antioxidant activity also measured by studying
the stability of oil by the use of rancimat method. All treatments exhibited
antioxidant activity. Statistical analysis results were shown that the
pomegranate peel extract treatment was significantly (P<0.05) superior than
the orange peel extract and ginger extract treatments whereas, it was not
significant difference about propyl gallate treatment.
Objective: Many children experience acute asthma exacerbations ,Many children
also require hospitalization despite treatment in an emergency department with current
standard therapy (corticosteroids ,and inhaled salbutamol). These hospitalizations
may be
avoided if effective adjunctive therapies can be developed to adequately treat severe
exacerbations.
