The present study was undertaken to investigate the ability of antioxidants Coriander sativum L . (cilantro ) and Allium sativum L.(garlic ) to protect against mercuric chloride induced reproductive toxicity in male rats .A sub Lethal chronic exposure (0.12mg/kg B.W mercuric chloride )resulted in a decrease of body weight, testicular weight and testosterone hormone with regressed histological properties of testis , epididymis and pre - cancerous changes in epididymis .These changes were ameliorated with the administration of cilantro and garlic .The results of our study suggested that the mentioned antioxidants exert significant protection against mercuric chloride induced male reproductive toxicity and provide a strong evidence for the beneficial role of antioxidant vegetables in prevention of mercury toxicity

The present study was conducted to evaluate the effect of Cumin on diabetes mellitus induced by alloxan in rats. Male Wister rats were used, and randomly divided into five groups (6-8 rats for each group): The first group: was administered distilled water and served as normal control, the second group: induced diabetes by single subcutaneous injection of alloxan 100 mg/kg.body weight and served as diabetic control, the 3,4,5 groups was administered 50,100,200 gm/kg of rat's forage respectively for four weeks, then diabetes are induced in this groups by same route as above. Cumin treatment in all doses lead to significant decrease glucose levels, and triglyceride and significant decrease in cholesterol level in dose 100, 200 gm/kg of forage and no change occur in total protein level. These results indicate that cumin have a role in delaying of diabetes through the effects of cumin in decrease some biochemical parameters

The antibacterial activity of the aqueous, ethanolic and methanolic extracts of Lawsonia inermis (henna) leaves were tested against 46 isolates of Staphylococcus aureus isolated from raw milk, also tested against standard bacteria (Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ATCC 27853). The highest antibacterial potency was observed for the methanolic extract with zone of inhibition (14.3043 ± 1.8722 mm), followed by ethanolic (12.9565 ± 2.0106 mm) then aqueous (11.6304 ± 2.2446 mm). The effect of methanolic extract against methicillin resistant S. aureus (MRSA) isolates was the excellent in comparison to other extracts (14.1± 1.88 mm) zone of inhibition followed by ethanolic (12.91 ± 2.372 mm) then aqueous (12 ± 2.41 mm). The isolates were subjected Kirby Bauer method to test their antibiotic susceptibility pattern, substantial antibiotic resistance were shown by 46 (100%) of isolates for ampicillin. Moderate resistance was shown by 31(67.4%) for oxacillin and low resistance was observed by erythromycin. The preliminary phytochemical analysis of the extracts revealed that the presence of high amount of phenolic compounds in methanolic extract (5.4) mg/ml, ethanolic (4.9) mg/ml and aqueoeus (3) mg/ml. MRSA provides a prospecting for new compounds which may be particularly effective against infections that are currently difficult to treat (1). Aims of the conducted study are: 1) an attempt to determine the antibacterial activity of aqueous, ethanolic and methanolic extracts of henna (Lawsonia inermis Linn) leaves against S. aureus isolates, and Gram negative bacteria. 2) antibiotic susceptibility pattern of the isolates. 3) explore the biochemical constituents of extracts.

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.
