The aim of this study is to evaluate the effect of the auto-omental graft on the fracture healing after destruction of the periosteum around the fracture site in rabbits. Eight mature healthy rabbits of local breed were employed to performed transverse fracture in the mid shift of the femoral bone, under general anesthesia and highly aseptic technique, then destruction of the periosteum was done about 1 cm away from each end of the fragments bone. The immobilization by intramedulary pinning, then the animals were divided into two equal group. The control group was left to follow the healing process, while in the treatment group the auto- omental graft was used to cover the fracture site. This graft was taken from the laparotomy of the left side and weekly radiographic examination performed for 10 weeks. The result is revealed that the omental graft play an important role in promote the fracture healing which was evident during the early new bone formation at the end of the second week compare to the control group which the sign of the callus formation was obvious lately at the end of the third week. The nature of the callus formation of the treatment group was limited to the fracture site and quickly cross the fracture site .While in the control group the new bone formation was heavy unlimited and need 8-9 week to bridge the fracture fragments. The omental graft play role in starting the remodeling phase, by decreasing the amount of the callus formation, with the signs of increase of the callus density, and marked of incorporation of the callus formation with the cortical bone

The present study showed that the ovary of adult turkey hens Meleagris Gallopavo is covered with simple cuboidal epithelium (germinal epithelium). Internally, two distinct regions can be distinguished. The cortex, a peripheral region contains a numerous follicles in different stages of development that are classified as primordial, primary, secondary and tertiary follicles. The primordial follicle appear distributed to the surface of sub capsular cortex surrounded by a single layer of follicular cells contains a small oocyte, showing a cytoplasm of filamentous aspect. The primary follicle appear distributed in the periphery and middle of the ovarian cortex contains and oocyte that shows an homogeneous cytoplasm with fine granules.

Present study was to detect the ordinary benzene on ossification in the long bones of themouse embryos Musmusculus L.conducted the current study, 56 mice adult (16 male& 40female) the females were divided into four groups, first for the control of the three treatmentgroups wasexposed to ordinary benzene concentration (4.5ppm, 9ppm, 45ppm) hours / dayfor 45 days and then married with intact males and took 20-day embryos,the results refer thatthe treatment groups showed significant decrease p< o.o5 revealedin the centers ofossification compared with control group.

A total of 35 Sprague-Dawley adult rats were used to investigate the effect of aluminium toxicity on behavioural patterns of adult female rats and learning ability of offspring. Rats were allotted into 4 groups, group one received 2g/l anhydrous aluminium chloride (n=10), group two received 3g/l anhydrous aluminium chloride (n=10), group three received 3.5g/l anhydrous aluminium chloride in drinking water (n=10) and control group did not receive anhydrous aluminium chloride (n=5) from 8th day of pregnancy till weaning of pups. The obtained results showed that feeding time increased significantly in 2g/l and 3.5g/l anhydrous aluminium chloride groups than control one, while, litter licking frequency and nursing time increased significantly in 2g/l anhydrous aluminium chloride than other groups. On contrary lying time decreased significantly in rats treated with 2g/l anhydrous aluminium chloride than other groups, licking and scratching decreased in 3g/l and 3.5g/l anhydrous aluminium chloride groups. In considering, the time spent in closed arms by offspring pups exhibited much times significantly than control group, while, time spent in open arms of elevated plus maze decreased significantly in all treated groups than control group. On the other hand, number of entries in open arms significantly decreased in treated groups than control one.

In this study a total of 2230 sheep (one-three years of age) were serologically surveyed in three selected areas in Libya (Western, Middle and Southern areas) to specify foci of infection and determination of the prevalence of ovine brucellosis using Rose Bengal Plate Test and Rivanol test. Prevalence of brucellosis in this study revealed 4%, 0%and 0%, respectively. Only the western area showed positive cases, while the Middle and Southern areas showed no serological evidence of brucella infection.

Thirty two cattle, had no neurological syndrome, were serologically positive to brucellosis by using Tube agglutination and Rose Bengal Tests, by the official veterinary authority in Beni Suef province, Egypt. These animals were slaughtered in Beni Suef abattoirs during the project of control and eradication of brucella positive animals in Beni Suef province. Postmortem examination was performed and the brain was mechanically removed. Longitudinally the brain was cut; one half was fixed in formalin 25% for 2 weeks and the other one were sent to microbiology department for bacteriological isolation. Transverse sections were done in the fixed tissue and samples were collected from cerebrum, cerebellum, medulla oblongata, thalamus, hypothalamus, and caudate nucleus. These samples were processed according to Bancroft and Gamble (2008). From the thirty two brain samples, no isolates of brucella species were recovered. From the thirty two brain samples, no isolates of brucella species were recovered. Brains of slaughtered animals showed no pathological lesions grossly. Microscopically, inflammatory reactions, degeneration, malacia, demyelination, pigmentation,and vascular changes were detected.

This study was conducted to study the UV protective effect against Haemonchus contortus infection in goats. Sixteen male goats were divided into 5 groups, control infected, control uninfected and UV 30minutes; UV 60minutes and UV booster 60minutes exposure. The UV groups were exposed to UV irradiation at wave length 254nm for 30 and 60 minutes. The UV booster 60min was administrated 2 doses of exposed larvae with an interval of one month. All groups except the control negative one were challenged for 42 days from the beginning. In UV booster 60min had reduction in egg count per gram feces and worm burden (93% & 34 % respectively). These parameters were similar in control infected, UV 30min and UV 60min groups. Increases in levels of antibodies were found in goats of UV booster 60min group the other groups. Finally, 2 doses of UV 60min exposure could protect goats from H. contortus.

Assessment of the neutralizing antibody response to the attenuated strain of peste des petits ruminants Nigerian strain (75/1) in 5 pregnant ewes revealed a geometric mean titre of 194, four weeks post Vaccination. Such an appreciably high titre was found to be dropped to 73.5, throughout 48 hours post parturn. Suckling kids born to these dams passively acquired a titre of 84.5 throughout their first month of life that dropped to 48.5 at the age of 2 months. At their 5th month of age their immune titre was found to be only 4. Data generated from this study might be of value in launching vaccination campaigns against peste des petits ruminants disease.

Micronization of chemical compounds is a new promising field as it reduces the size of the particles thus it increases their penetration power. Many theories prove that micronized particles are more effective even in very low concentration as compared to its normal size. Paracetamol is a commonly used effective analgesic and antipyretic agent for relief of mild and moderate pain. However, deliberate overdose or accidental overdose can cause hepatotoxicity. In the present study, we have evaluated and compared between the hepatoprotective and antioxidant effects of vitamin C and micronized vitamin C against paracetamol induced hepatotoxicity in rats. Activities of liver enzymatic markers (Alanine amino transferase "ALT", Aspartate amino transferase "AST", Alkaline Phosphatase "ALP") and total protein "TP" concentration were estimated in serum. Lipid peroxidation "MDA" and antioxidant status (reduced glutathione "GSH " concentration, glutathione reductase "GR", catalse and super oxide dismutase "SOD" activities) were measured in tissue homogenates. Paracetamol administration (600 mg/ Kg B.wt.) significantly increased the liver enzymatic markers and decreased the total protein level. It also increased hepatic lipid peroxidation “MDA” and the activities of both catalase and SOD while it decreased GSH content and glutathione reductase (GR) activity. Treatment of vitamin C and micronized vtamin C restore the measured parameters nearly to their normal levels. Finally, micronized vitamin C has a more potent effect than ordinary vitamin C.
