The effect of garlic (Allium sativum) on lipid profile in normal and hyperlipidimic ratswas studied. Forty rats were allocated randomly into four groups, each of ten rats. The firstgroup was received distilled water as acts as a control group. The second and the third groupwere given high cholesterol diet (2% cholesterol) for 4 weeks, one considered as a hypercholesterolimic group and the other was hyper cholestermic which received alcoholic extractof garlic at a dose of 300mg/kg B.W for 4 weeks. The fourth group was given alcoholicextract of garlic at the same dose and the same duration. The serum lipid profile of theexperimental animals in all groups was assayed and the resulting values statistically analyzed.The values of total cholesterol (Tch), Triglyceride (TG) and low density lipoprotein(LDL) were significantly decrease in groups received garlic extract comparing with controland hyper cholesterolimic groups with non significant increase in high density lipoprotein(HDL) in all groups.Garlic may be recommended as an anti atherogenic agent and is suggested to be usedwith food in patient with hyperlipidemia.

Out of fourty six samples collected from impetigo patients, fourty-two bacterial
isolates were obtained, Staphylococcus aureus was constitute 24 isolates, Streptococcus
pyogenes was 14 isolates and Proteus mirabilis was only 4 isolates . The sensitivity of these
bacterial isolates were tested against 7 different antibiotics . It was shown that the highest
sensitivity of there isolates were against Erythromycin and Mithicillin , were as both
Ciprofloxacin and Piperacillin were the most active inhibitors of the tested bacteria . On the
other hand , the activity of vinegar solution of different concentration were tested against the
different bacterial species isolated from impetigo cases, The results showed that the majority
of bacterial isolates were sensitive to concentration between 2-32 mg\ml. The MIC and MBC
of vinegar solutions toward the three bacterial species were as follows ; for Proteus mirabilis
were 0.5-1.0 mg\ml , for Streptococcus pyogenes were 0.5-0.75 mg\ml and for Staphylococcus
aureus were 0.15-0.25 mg\ml respectively . .

Advances in the design of keystream generator using swarm intelligence techniques are
reported.In this paper particle swarm optimization algorithm for generating random keystream
with large complexity is presented. Particle swarm technique is adapted to locate the
requirements(larg period ,larg linear complexity, good randomness and high order of
correlation immunity). The definitions for some cryptographic properties are generalized,
providing a measure suitable for use fitness function in a particle swarm algorithm, seeking
randomness that satisfy both correlation immunity and the large linear complexity. Results are
presented demonstrating the effectiveness of the proposed method.

with the stopping powers calculated from the Zeigler formula have been used to calculate the
n-yield for reaction.

One of the most important characteristics of using fractal image coding in hiding
images is the encoding process that involves very long time complexity. In this paper
new hiding system is proposed that hide secret image (color or gray) into cover image
(color) with reducing the time of encoding process 10 times less than classical
systems that use block indexing as descriptor with fractal coding. Affine transform is
used in matching process to find the closer cover block for each secret block and least
significant bit method to embed the coefficient affine transform. The results indicated
that the encoding time is actually reduced and hiding rate reach to 100% and the
quality of extracted secret image is still within the acceptable level.

In this study, we evaluated the effect of Apple- lite for 4 weeks on body weight, lipid profiles,
kidney functions and histological structure of kidney in male rats. Twenty adult male albino rats (240
250 gm) were divided into 2 groups: The first group was considered as control group. The second
group was treated orally with Apple- lite (55 mg/kg b.w) by use of intragastric tube. Different
physiological parameters were performed including recording of the body weight and measuring lipid
profiles, creatinine and urea levels. Body weight gain, total cholesterol, triglyceride, LDL cholesterol,
and VLDL cholesterol levels were significantly (p< 0.05) reduced in Apple- lite treated rats when
compared with the control rats. Urea level was significantly (p< 0.05) increased in Apple- lite treated
rats, but HDL cholesterol and creatinine levels were none significantly (P >0.05) increased when
compared with the control rats. Histological examination of Apple- lite treated rat’s kidney showed
aggregation of inflammatory cells (monocytes) around glomerulus, fibrosis around Bowman's capsule,
and congestion of blood vessels. From these results it can be conclude that the treatment with Apple-
lite produced a significant reduction in body weight and lipid profiles, but it is incapable of improving
the kidney functions. Also there are histopathological effects on kidney tissue in treated rats.

This study was carried out to evaluate proteins encoded by different fragments of
HCV genes for detection hepatitis C infection. Eighty eight Iraqi hepatitis C patients were
involved in this study, these patients attended the Gastroenterology Department of Baghdad
Teaching Hospital during the period from December 2009 to March 2011. These patients
included 58 males and 30 females with ages ranged between (16-64) year. The results of this
study showed that 88 specimens were immunoreactive to one or more of the 4 HCV
recombinant proteins, besides that 34 serum samples were collected from apparently healthy
individuals (included 21 males and 13 females) they served as a control group, all the samples
obtained from control group didn't show any reactivity to hepatitis C virus.Additionally, the
positive rates of anti-capsid ,anti-NS3,anti-NS4 and anti-NS5 were 77.2%,64.7%,55.6% and
46.5% respectively ,while 13.6 % reacted to capsid protein , 5.7% reacted to NS3 protein , in
addition , 3.4% reacted to NS4 protein , furthermore , 2.3% only reacted to NS5 protein .
Finally, all the 88 specimens (100%) were immuno-reactive to the mixed proteins. In
conclusion , Our results sustain different immunoreactivity of the HCV recombinant proteins
encoded by different fragments of C virus gene, therefore the mixture of all the protein
derived from HCV different regions should be applied in further HCV diagnostic test to detect
hepatitis C infection.
