The object of the present study was to assess the possible alterations in blood of sheep that may occur following intramuscular injection of tobramycin. Tobramycin was injected to 10 sheep at a dosage regimen of 5 mg/kg of body weight for 5 successive days. Two types of blood samples (with and without EDTA as an anticoagulant) were collected from the jugular vein before and after the antibiotic course. Tobramycin significantly (p arabic 13 English 83

The present study aimed at evaluation of the immuomodulatory effect of sulphadimidine by investigating its ability to affect constitutive expression of MHC-II molecules on B-cells, which are one determinant of antigen presentation and the vigor of immunity. Three groups of broiler chicken were used, the first two groups received 100 mg/kg and 200 mg/kg sulfadimidine, respectively, in drinking water; while the third group was left as control. Bursal samples were taken after 7 and 14 days of treatment and checked for MHC-II gene expression by RT-PCR technique. The obtained results demonstrate that oral administration of sulphadimidine inhibited the expression of MHC-II mRNA in bursal of Fabricius of broiler chicken in a dose and age dependent manner. This finding is of clinical importance as many farmers routinely add sulpha drugs to drinking water as a prophylactic measure against some infections; yet the data presented in this study doesn't recommend this managing behavior. arabic 11 English 83

he unique characters of camel’s milk make it used extensively in the field of medicine as antidiabetic, anti-microbial, and hepatoprotective agent.
