Experiments were performed with the aim of investigating the effect of packing on erythrocyte osmotic fragility (EOF) and malondialdehyde (MDA) concentration in donkeys, and the effect of ascorbic acid (AA). Twelve apparently healthy donkeys raised under the traditional extensive system served as experimental subjects. Six donkeys administered orally with AA (200 mg/kg) and subjected to packing were used as experimental animals, whilst six others not administered with AA served as controls. Blood samples were collected pre- and post-packing from all the donkeys for the determination of MDA and EOF. At 0.3% Sodium Chloride (NaCl) concentration, the percentage haemolysis was 93.69% ± 2.21% in the control donkeys and the value was significantly (<em>P</em> &lt; 0.05) higher than the value of 71.31% ± 8.33%, recorded in the experimental donkeys. The post-packing MDA concentration obtained in the control donkeys was 39.62 µmol ± 4.16 µmol, and was not significantly different (<em>P</em> &gt; 0.05) from the value of 35.97 µmol ± 2.88 µmol recorded in the experimental donkeys. In conclusion, the increase in haemolysis obtained in the donkeys suggested that packing induced oxidative stress, which was ameliorated by AA administration.

A review was conducted to provide comprehensive update on Rift Valley fever (RVF) in Tanzania, with particular attention devoted to trend of occurrence, epidemiological factors, socio-economic impact and measures which were applied to its control. Information presented in this paper was obtained through extensive literature review. Rift Valley fever was documented for the first time in Tanzania in 1977. This was followed by epidemics in 1997 and 2007. Contrary to the latest epidemic in 2007 sporadic cases of RVF during the previous epidemics were confined to mainly livestock and mostly affecting northern parts of Tanzania. The latest disease epidemic expanded to cover wider areas (mostly northern and central zones) of the country involving both human and domestic ruminants. During the latest disease outbreak 52.4% (n = 21) of regions in Tanzania mainland were affected and majority (72.7, n = 11) of the regions had concurrent infections in human and animals. Phylogenetic comparison of nucleotide and amimo acid sequences revealed different virus strains between Kenya and Tanzania. Epidemiological factors that were considered responsible for the previous RVF epidemics in Tanzania included farming systems, climatic factors, vector activities and presence of large population of ruminant species, animal movements and food consumption habits. Majority of the RVF positive cases in the latest epidemic were livestock under pastoral and agro-pastoral farming systems. The disease caused serious effects on rural people’s food security and household nutrition and on direct and indirect losses to livestock producers in the country. Psycho-social distress that communities went through was enormous, which involved the thinking about the loss of their family members and/or relatives, their livestock and crop production. Socially, the status of most livestock producers was eroded in their communities. Cessation of lucrative trade in ruminants resulted in serious economic losses to the populations who were totally dependent upon this income. Livestock internal market flows drastically dropped by 37% during latest epidemic. Rift Valley fever epidemics had dramatic impact of RVF outbreak on the international animal trade in which there was a 54% decline in exports equivalent to loss of $352 750.00. The estimate of loss as a result of deaths for cattle was $4 243 250.00 whereas that of goats and sheep was $2 202 467.00. Steps taken to combat epidemics included restriction of animal movements, ban of the slaughter of cattle and vaccination of livestock and health education. From past epidemics we have learnt that each subsequent outbreak had expanded to cover wider areas of the country. The disease had dramatic socio-economic impacts both at community and nation at large. The main challenges related to the control of RVF outbreaks included lack of preparedness plan for RVF, poor coordination and information transmission, limited facilities and manpower for RVF outbreak intervention. Control of the 2007 RVF epidemic was largely the result of animal and human health agencies working in an integrated manner.

Study the effect of nitric oxide donor on sperms membrane integrity and volume and their relationship with viability and sperm motility. This study was done usingtwo groupseach one contained 10 samples first one exposed to eight different gradient of hypotonic solutions containing Sodium nitroprusside (SNP)and second 10 samples diluted with gradient hypotonic solutions without Sodium nitroprusside,Bull semen tris dilution treated with Sodium nitroprussidein that protected the sperm fromosmocellular changes stress. The results showed tolerance sperm to gradient hypotonic solution in sperm swelling and classic spermatocrit marked significance by the relative volume shift volumetric data. In addition the SNP had sperm protection to osmolarity tested and give improvement viability and sperm motility. Hypotonic media tonicity that may be attributed to direct liberation of Nitric oxide that produced vital regulation of Na-K ATPase and Calcium channels of sperm membrane

Invegstigation of antibacterial activity of water,ethanolic and methanolic extracts of Oregano(Origanum vulgare)and compared with Vancomycin, Erythromycin, cloxacillin ciprofloxacin and Streptomycin antibiotics was carried out on gram positive and Gram microorganisms for different extracts. The zone of inhibition varies depending on bac-terial ranges from 12 to 26, 14 to 20 and 18 to 22 for water,ethanolic and methanolic With anMICs of(0.167 0.1033) mg/ml against Bacillus subtilis and against Staphylococ-cus aureus was(0.21±0.102) μg/ml. when comparing the extracts MICs with those of antibiotics. All extracts showed pronounced antibacterial effects against both Gram posi-tive and Gram negative bacteria with a significant differences between the effect of extracts & antibiotics ( p < 0.05 )

The present study designed for determining the effect of malathion on some blood parameters on male and female albino mice. The study was done on 42 mice divided in three groups,14mice per group 7per sex in each group. During two months, with (250mg/kg,500mg/kg) malathion doses there were clinical disorders such us salivation ,quaking, and diarrhea were observed in addition to significantly decreases (p

The aim of this study was to evaluate the anti-inflammatory and the ulcerogenic activity of 5-(3-chloro-1-benzothien -2-yl)-4-phenyl-4H-1,2,4-triazole-3-thiol. The anti-inflammatory effect of the compound was determined by comparing it with a standard drug (naproxen). The anti-inflammatory effects were studied by using carrageenan-induced paw edema method and Cotton pellet induced granuloma in rats and the ulcerogenic liability was assessed and compared with a standard drug. The results showed that the compound had an obvious anti-inflammatory effect and the activity is comparable to that of the standard drug with less ulcerogenic effects.

Since the invention of laser in 1960, lasers have been developed and approved in many fields. Lasers can now be regarded as practical tools with unique properties that have been utilized effectively in several applications in fields of medical and biological sciences. six bacterial isolates were isolated from human samples of diabetic foot infections, which used for preparation of vaccines. The experiment was conducted on fifteen adult male rabbits, they were divided into three groups with 5 rabbits each. After irradiation of the bacterial suspensions with the diode laser for different exposure times and different frequencies, and the wavelengths used were (660, 820, 915 ) nm, the growth of bacterial isolates decreased until killed of bacteria at ( 40) min. The aim of the current study was to preparation of vaccines (live attenuated and killed) by irradiation of the bacteria by the low level diode laser. Wavelength (660) nm was more effective in killing the bacteria, and the variations were not significant between the live attenuated and the killed vaccine
