Ethidium bromide-agarose gel electrophoresis is an extensively used procedure for the analysis of DNA; it has been reported to be sensitive to as little as 50 ng of DNA (7). The standard methods for staining gels involve adding 0.5 μg/mL ethidium bromide to both the agarose gel and the running buffer or soaking the gel in a solution of ethidium bromide after electrophoresis has been performed (...

In its earliest stages when treatment will produce the most favourable results, tuberculous meningitis may be difficult to diagnose clinically, since other infective non-bacterial conditions of the central nervous system may present a similar clinical picture at their onset. Since the bromide partition test and its use in the diagnosis of tuberculous meningitis were described (Taylor, Smith and...

A novel simple, sensitive and rapid kinetic-spectrophotometric method is proposed for the determination of trace amounts of bromide. The method is based on its catalytic effect on the oxidation of methylene blue (MB) by hydrogen peroxide in strongly acidic solution. The oxidation reaction is activated by large amounts of chloride and can be monitored spectrophotometrically by measuring the decr...

a highly selective electrode for bromide ion based on aza pyrilium derivative as an excellentionophore is described.the sensor exhibits a good linear response with a slope of ( 60±1 ) mv per decadeover the concentration range of ( 1×10-3 – 9×10-6 m ) , and a detection limit of ( 3×10-6 m ) of bromideions .the electrode response is independent of ph in the range of(4.0 –9.5).selectivity coeffici...

PURPOSE We present six patients with epilepsy of infancy with migrating focal seizures (EIMFS) and provide a comprehensive evaluation of potassium bromide therapy. METHOD Between February 1, 2007 and July 31, 2012, six patients who met the diagnostic criteria of EIMFS were treated with potassium bromide. Potassium bromide was added to other antiepileptic drugs (AEDs) in doses ranging from 30 ...

OBJECTIVE To compare efficacy and safety of treatment with phenobarbital or bromide as the first-choice antiepileptic drug (AED) in dogs. DESIGN Double-blinded, randomized, parallel, clinical trial. ANIMALS 46 AED-naïve dogs with naturally occurring epilepsy. PROCEDURES Study inclusion was based on age, history, findings on physical and neurologic examinations, and clinicopathologic test ...
