This study was carried out to evaluate the presence of some antimicrobial residues in broilers slaughtered in Gaza strip. Three hundred sixty five chicken breast samples were collected from poultry slaughterhouses distributed in the study area. Samples were screened for the presence of β-lactams, aminoglycosides, macrolides and tetracyclines (as groups) using a 7-Plate bioassay method. Chicken carcasses were divided into three categories; category (A); ≤ kg, category (B); > -2 kg and category (C)> 2 kg. A total of 88 (%) samples were positive for one or more of antibiotic residues, (%) of them were from category (A), followed by (%) for category (B) and the least category was group (C) (%). Tetracyclines, aminoglycosides, β-lactams and macrolides residues were detected in 41(%), 26(%), 20(21%) and 8(%) respectively. Results confirmed the presence of antibiotic residues in poultry meat samples. Thus, it is highly recommended to establish a national monitoring program for antimicrobial residues in foods.
In cerebral edema , Dexamethasone Sodium Phosphate injection, USP is generally administered initially in a dosage of 10 mg intravenously followed by 4 mg every six hours intramuscularly until the symptoms of cerebral edema subside. Response is usually noted within 12 to 24 hours and dosage may be reduced after two to four days and gradually discontinued over a period of five to seven days. For palliative management of patients with recurrent or inoperable brain tumors, maintenance therapy with either Dexamethasone Sodium Phosphate injection, USP or dexamethasone tablets in a dosage of 2 mg two or three times daily may be effective.
