BACKGROUND The diagnosis of brucellosis is frequently difficult to establish. This is not only because clinically, the disease can mimic any infectious and noninfectious disease, but also because the established diagnostic methods are not always successful. In this study, we have tried to evaluate PCR techniques in the diagnosis of brucellosis in comparison(More)
In this study we report for the first time the distribution of human platelet alloantigens (HPA) in Saudis. These antigens are implicated in the pathophysiology of alloimmune thrombocytopenia. We collected blood samples from 84 healthy male Saudi blood donors. DNA isolated by salting-out and ethanol precipitation was amplified for genes HPA 1-5 using the(More)
(st4529, st4547, st4532, st4545, and st3018, with accession numbers AF060368, AF052426, AF077666, AF077668, and AF077669, respectively). The newly found group A st4545 sequence was more similar to various group G streptococcal emm sequences than to known group A emm sequences. One group G isolate had a previously found group G 5' emm sequence (stLG6,(More)
To assess whether SAV could influence the effects of carbon tetrachloride (CCL4) exposure, mice were treated with SAV in doses of 100, 200, 300 and 400  μg/kg body weight and the effects on oxidative status and kidney function were studied. Serum levels of creatinine, malondialdehyde (MDA), and blood urea, together with renal and hepatic levels of MDA,(More)
This study aimed at investigating the oxidative stress ameliorating effect, lipids profile restoration, and the anti-inflammatory effect of Samsum Ant Venom (SAV) in induced endotoxemic male rats, injected with bacterial lipopolysaccharides (LPS). Results revealed that LPS significantly increased the oxidative stress indications in LPS-injected rats. A(More)
This study was conducted to appraise the protective effect of Indigofera oblongifolia leaf extract on lead acetate (PbAc)-induced nephrotoxicity in rats. PbAc was intraperitoneally injected at a dose of 20 mg/kg body weight for 5 days, either alone or together with the methanol extract of I. oblongifolia (100 mg/kg). Kidney lead (Pb) concentration;(More)
One of the diagnostic characters of the ponerine ant genus Brachyponera is the presence of a mandibular pit near the insertion of the mandible. This paper describes the morphology and ultrastructure of a novel intramandibular gland in B. sennaarensis, that is associated with this pit. The gland appears as a conspicuous epithelium that lines the invaginated(More)
Ant venom shows antimicrobial, anti-parasitic and anti-inflammatory activities, both in vitro and in vivo. Our recent studies have confirmed the role of samsum ant venom (SAV) as a powerful antioxidant. This study aimed to investigate whether SAV as a potential treatment for CCl4-induced acute liver toxicity in an animal (rat) model. Thirty-two rats were(More)
Babesiosis is caused by intraerythrocytic protozoan parasites transmitted by ticks and affects a wide range of domestic and wild animals and occasionally humans. The current study aimed to investigate the effect of B. divergens infected erythrocytes on spleen histopathology, cell cycle alteration, and the presence of oxidative stress. Mongolian gerbils were(More)
