We report the development of a simple and inexpensive assay for the detection of DNA polymorphisms and mutations that is based on the modification of mismatched bases by potassium permanganate. Unlike the chemical cleavage of mismatch assay, which also exploits the reactivity of potassium permanganate to detect genomic variants, the assay we describe here does not require a cleavage manipulatio...

Acute toxicity study of potassium permanganate was carried out in Swiss albino mice. Potassium permanganate was administered at dose rate of 0.0, 500, 1000, 1500, 2000, 2500, 3000 and 3500mg/kg body weight to groups 1, 2, 3, 4, 5, 6, 7 and 8, ten per group for LD50 determination. The dead animals were posted for gross lesions. A predetermined dose of 160mg/kg of the chemical was administered to...

Freshly harvested mature tomato fruits were treated with different concentrations of potassium permanganate to evaluate their effect on color and texture of the fruits. This was to determine the degree of acceptability and shelf life of the tomatoes. Fifty grams of mature unripe tomato fruits was washed and weighed into a transparent plastic container containing different concentrations of pota...

2- Methylsulfonyl - 5- (1-methyl-5-nitro- 2 – imidazolyl ) 1,3,4 - thiadiazole ( 1 ) was prepared by twa independent routes.1) reaction of 1-methyl-2-formyl-5- nitroimidazole (3) with methyl hydrazinecarbodithioate gave the hydrazone 4. Reaction of compound 4 with acetic anhydride followed by potassium permanganate oxidation of the intermediate 5 gave the desired compound 1. 2) React...

Two simple, rapid and sensitive spectrophotometric methods developed for Chlorpheniramine Maleate (CPM) and Diphenhydramine Hydrochloride (DPH) determination in pure and pharmaceutical preparation using Potassium Permanganate. The solvent system used was potassium permanganate. The method developed by adding a known amount of permanganate to CPM and DPH in acid and alkaline medium, the unreacte...

OBJECTIVES To verify the influence of different etching procedures of the post-surface on microtensile bond strength values between fiber posts and composite core materials. METHODS 60 DT Light Posts were divided into 10 subgroups using five different chemical surface treatments and two composite materials to build-up the abutment. Chemical surface treatments including etching with potassium ...

BAL, E. and S. CELIK, 2010. The effects of postharvest treatments of salicylic acid and potassium permanganate on the storage of kiwifruit. Bulg. J. Agric. Sci., 16: 576-584 Kiwifruit (Actinidia deliciosa cv. Hayward) was used to investigate the effects of salicylic acid (0.5 mM, 1 mM) and potassium permanganate treatments on fruit quality and storage life during storage for two years. After tr...

A new method is described for determining in shales the amount of sulphides that dissolve in dilute hydrochloric acid. 1he samples are treated with hydrochloric acid under vacuum, and the hydrogen sulphide evolved is absorbed in potassium hydroxide and titrated with potassium _~'~ermanganate. The analytical results are expressed as FeS. INTRODUCTION During a study of the distribution of the sul...
