In the present study various extracts of Cyperus esculentus L. such as acetone, 50% ethanol, chloroform and petroleum ether were evaluated for their antibacterial activity against several human pathogens such as Escherichia coli, Staphylococcus aureus, Salmonella sp, Klebsiella pneumoniae, Proteus vulgaris, Pseudomonas aeruginosa and Citrobacter freundii, by using disc diffusion method. The act...

new two nano- sized schiff base complexes [m(l)], where l= 2, 2'-((1e, 1e')-(1, 2 phenylen bis (azanylylidene)) bis (methanylylidene)) bis (4-bromo phenolato) and m=cu or zn, (a, b complexes) were synthesized by ultrasonic irradiation. these complexes were characterized by elemental analysis, molar conductivity, ft-ir, fluorescence emission, 1h nmr, field emission scanning electron sp...

Background:The utility and efficacy of novel materials in tissue regeneration and antimicrobial therapy are contingent upon the employment of either blood derivatives rich in platelets or platelet-poor-plasma (PPP). This effect is largely mediated by the increased or decreased concentration of platelets in the plasma. The current study aimed t...

Bovine subclinical mastitis (BSM) is a serious economic concern to the dairy industry, and is difficult to control due to elusive clinical manifestations of the ailment. The disease with primarily of microbial aetiology is amenable to antibiotic therapy, but the outcome is uncertain due to involvement of a plethora of microorganisms, host-specificity of the pathogens, and incessant evolution of...

bacteria, an altered immune response, an altered histiocytic response or intrinsically abnormal macrophages [5]. The most common site of infection in females is the urinary tract and it is associated with infection with Gram-negative organisms, mainly Escherichia coli and Klebsiella sp. The extragenitourinary sites that are involved are the skin and the pulmonary, renal and gastrointestinal tra...

This study was done to determine whether salicylate could affect alterations in intestinal absorption induced by preparations of enterotoxigenic micro-organisms. It was found in rats that salicylate increased intestinal monosaccharide uptake in vitro and reversed the inhibitory effects induced by cell-free preparations of Staphylococcus sp., Candida sp. and Klebsiella sp. In vivo, salicylates i...

Ten patients received a 30-min infusion of amikacin (30 mg/kg) on day 1 and 15 mg/kg on day 2. Mean serum creatinine was 1.1 +/- 0.3 (standard deviation) mg/dl before and 1.0 +/- 0.3 mg/dl 3 days after the second infusion. Mean serum amikacin concentrations before, at the end of infusion, and 1, 6, 12, and 24 h after 30 and 15 mg/kg were 0, 157, 79, 31, 16, 5, 5, 85, 51, 19, 12, and 5 mg/liter,...

   Stability of bacterial flora in fish intestine is very important, because the intestine is an important organ for outbreak of microbial infections and other fish diseases especially when the fish have not been vaccinated. The aim of this study was to determine the bacterial flora of intestine in sturgeon juvenile in earthen ponds. The results can be applied to prevent the diseases occurren...

In this study, random sampling conducted and 90 individuals of Persian sturgeon having 3-5g weight, collected by trawling in 3 earthen ponds and 15 individuals having 10-20g weight, collected by small net in 3 fiberglass Vans. After recording of biometrical characteristics, the intestine and rearing water were cultured on TSA medium. Gram staining and complementary tests were conducted. In orde...

An extract of henna (Lawsonia inermia) was found to be active in vitroagainst gram (+) and gram (-) bacteria including Bacillus anthracis, B.cereus, B. subtilis, Enterobacter aerugenes,Escherichia coli 0128-B7, E.coli 055-B5, E. coliO127-B8, Proteus mirabilis, P. vulgaris, Pseudomonas aeruginosa Salmonella typhosa, S.paratyphi, Sarcina sp. Shigella dysenteriae type 1, S. dysenteriae type 7,...
