تم في هذا البحث دراسة تأثير فيتامين C في مستوى الكولسترول الكلي و الشحوم الثلاثية و البروتينات الشحمية عالية الكثافة HDL و البروتينات الشحمية منخفضة الكثافة LDL في الدم عند الأرانب المجهدة ببيروكسيد الهيدروجين (H2O2) و ذلك باستخدام 30 أرنباً، قسمت إلى ثلاث مجموعات بالتساوي: مجموعة أولى غير مجهدة (الشاهد)، المجموعة الثانية (مجهدة ببيروكسيد الهيدروجين) تركت دون معالجة حتى نهاية التجربة، المجموعة الثالثة (مجهدة ببيروكسيد الهيدروجين) و جُرِّعَت محلول فيتامين سي 100ملغ/كغ لمدة خمسة أسابيع .
In research we studied the effect of vitamin C on the level of total cholesterol ،triglycerides ، (HDL) and (LDL) in the stressful rabbits blood by hydrogen peroxide (H2O2) . We used 30 rabbits were divided into three groups:First groupnot stressed (control group) ، Second group (Group stressed by H2O2) left without treatment until the end of the experimental period ، third group (Group stressful by hydrogen peroxide) was given orally vitamin C solution at a rate of 100 mg / kg of body weight per a day for five weeks.

This study was conducted in the laboratories of the Faculty of Science In the spring
on 2013, after being subjected to gavage for 4 weeks through a standard diet supplemented
fat by 3% to two groups (6animales per group) the experimental group beca
me aqueous
extract 150 mg/kg Body weight for 4weeks while the control group became standard food
and tap water ad libitum.
The Blood samples were collected each week, and then the serum samples were
taken to the biochemical tests to determine total cholesterol, triglycerides and glucose
levels in biochemistry laboratory of the Institute of Intermediate medical in Tishreen
University.
This study was conducted at Gharabo farm, Fac. Agric. Damascus
Universityin order to determine the effect of heat sress and level of vit. C on the
blood indicators of of Japanese quailc A total of 252 females Chicks were
distributed randomly into
two groups (G and G2) at one day of age, The chicks
in G1were subjected to an ideal temperature required according to their age up
to 30 days old, while the chicks in G2 were subjected to heat stress at 42 °C
during the daytime from 8 am to 5 pm and to ideal temperature from 5pm to
8am for the same period of rearing. Chicks of each group were distributed into
three subgroups given three levels of vitamin C: 0, 10 and20 g/l, with three
replicates for each sub-group during the rearing period. Blood samples were
collected from eighteen birds selected randomly from each group. Results
indicated that there was a significant increase in both red blood cells and
hemoglobin in the stressed group.
There are a lot of studies with conflicting results about the correlation between blood
levels of vitamin D and lipid profile (total cholesterol, LDLc, HDLc) and the effect of
treatment with vitamin D supplements on it. This study aimed to investig
ate the effect of
vitamin D and calcium supplements on lipid profile.
This study included 59 volunteers who received these supplements for prevention of
osteoporosis as a prescription from orthopedic doctors between 11/2016 to 1/2018. The
average of age was 49±8 years. The plasma values of TC, LDLc, HDLc were measured
using enzymatic colorimetric method ( Biosystems kits ) in Tishreen hospital before
treatment and after two months. The results were analyzed by T-Student test, and P value
<0.05 was considered significant. The mean plasma levels of LDLc before treatment were
(100.983 ±28.36) mg/dl, and after two months of treatment were (102.249±27.478) mg/dl,
and the difference was not significant. The mean plasma levels of HDLc before treatment
were (68.056 ±14.369) mg/dl and after two months of treatment were (62.715 ± 14.39)
mg/dl, and the difference was significant. We advise to measure plasma lipid levels during
treatment with these supplements depending on the changes that observed in this study.
In this research, the quantity of vitamin C which extracted from fresh fruits and
vegetables was evaluate by using titration method with 6-2 Dichloro phenol andovinol, and
studying the effect of conservation and different temperatures (30, 60, 90)
°C which used
in cooking on content of vitamin C for some samples. Also this search included studying of
the effect of iron ions on content tomato, orange and lemon of vitamin C.
The results showed that the concentration of vitamin c in studied samples: parsley,
red pepper, green pepper, lemon, orange and tomato was (8, 22, 36, 144, 175, 133)
mg/100g respectively. Losing of the vitamin was (66%, 65%) when we save the leaves and
stalk of parsley for 24 hours respectively, when exposure the parsley leaves to the
temperatures (30, 60, 90) c° the losing percentage was (24 %, 41%, 62 %), While the
losing was (79%, 65%, 39%) when injected each of tomatoes, oranges, lemons with
dissoluble of iron.
This experiment was conducted at Kharabo farm, Faculty of Agriculture,
University of Damascus. A total of 252 chicks of Japanese quail breeder females
were distributed on the first day of life into two groups, Gicks in G1 were
reared from 1-28 day
s of age under ideal required temperature according to
their age, while chicks in G2, were subjected to heat stress from 8 am to 5 pm at
42 °C from the first day of hatching until 28 day of age and to the ideal
required temperature from 5 pm until 8 am. Chicks of each group were
distributed into three subgroups, with three replicates per subgroup.
