Background: Diethylcarbamazine citrate (DEC) is the drug of choice for the treatment of lymphatic filariasis, a disease which affects people in the tropical areas of the world. Mass treatment with DEC is recommended for control of lymphatic filariasis and in this connection, there is a need for an assay which could be used for the purpose of medication control. Objective: The present study is a...

Of the five species of white rot fungi evaluated for their ability to decolorize Amaranth, Remazol Black B, Remazol Orange, Remazol Brilliant Blue, Reactive Blue, and Tropaeolin O in agar plates, Bjerkandera sp. BOS55, Phanerochaete chrysosporium, and Trametes versicolor displayed the greatest extent of decoloration. In static aqueous culture, the three cultures formed fungal mats which did not...

Taste drives appetite and protects us from poisons. So, we like the taste of sugar because we have an absolute requirement for carbohydrates (sugars etc.). We get cravings for salt because we must have sodium chloride (common salt) in our diet. Bitter and sour cause aversive, avoidance reactions because most poisons are bitter (most bitter substances are bad for you certainly in excess) and off...

Two spectrophotometric methods have been described for the assay of verapamil hydrochloride in drug formulations. Method A is based on the oxidation of the drug with potassium metaperiodate in sulfuric acid medium to give colored product, which absorbs maximally at 425 nm. Method B involves the formation of colored chloroform extractable ion-pair complex of the drug with tropaeolin 000 No.1 at ...

Botek P., Poustka J., Hajšlová J. (2007): Determination of banned dyes in spices by liquid chromatography–mass spectrometry. Czech J. Food Sci., 25: 17–24. A simple and rapid multiresidue method for the determination of nine banned synthetic dyes in various spices has been developed. Reversed phase HPLC coupled with mass spectrometry (tandem in time – ion trap mass analyser) was employed for th...
