An experiment was performed to evaluate the efficacy of potassium permanganate (KMnO4) as a prophylactic and therapeutic treatment of an experimental subacute infection of Flavobacterium columnare in channel catfish, Ictalurus punctatus. Fish were cutaneously abraded and divided into five treatment groups: (i) challenged by waterborne exposure to F. columnare and not treated with KMnO4 (positiv...

Potassium permanganate (KMnO4) is rarely used for suicidal attempt. Its ingestion can lead to local as well as systemic toxicities due to coagulation necrosis and damage, caused by free radicals of permanganate. We recently managed a case of suicidal ingestion of KMnO4 in a lethal dose. She had significant narrowing of upper airway leading to difficult intubation as well as hepatic dysfunction ...

Many mutation detection techniques rely upon recognition of mismatched base pairs in DNA hetero-duplexes. Potassium permanganate in combination with tetraethylammonium chloride (TEAC) is capable of chemically modifying mismatched thymidine residues. The DNA strand can then be cleaved at that point by treatment with piperidine. The reactivity of potassium permanganate (KMnO4) in TEAC toward mism...

abstract the effect of different levels of potassium permangenate (kmno4) on quality of mango fruits were studied over a period of 21 days. a factorial trial in the form of complete randomized design as three levels of kmno4 (0, 5 or 10 g. kg-1 fruit) and three time period (7, 14 or 21 days) was used. means were compared using duncan’s test (p< 0.05). compositional parameters (ph, acidity, tota...

Oxidation of soils with 333 mM potassium permanganate (KMnO4) has been identified as a means to quantify labile soil carbon (C) and may have potential for rapid measurement of biologically active soil C. In the current study, active C pools in several soils were estimated by oxidation with a range of KMnO4 concentrations and compared to estimates determined from carbon dioxide evolution during ...

A manganese immobilization technology in a fluidized-bed reactor (FBR) was developed by using a waste iron oxide (i.e., BT-3) as catalyst which is a by-product from the fluidized-bed Fenton reaction (FBR-Fenton). It was found that BT-3 could easily reduce potassium permanganate (KMnO4) to MnO2. Furthermore, MnO2 could accumulate on the surface of BT-3 catalyst to form a new Fe-Mn oxide. Laborat...

This study examined the photolytic degradation of C.I. Acid Red 73 AR73 diazo dye, in aqueous solution by combined UV, hydrogen peroxide and KMnO4. A continuous circulated photoreactor equipped with a low pressure mercury lamp 15 W, emission 253.7 nm was used. In the first step, potassium permanganate was used for decolourisation of AR73 dye solution. The effect of the key operating variables s...

The chorio-allantoic membranes of White Leghorn chick embryos at 10 to 12 days after laying were fixed in Palade's buffered osmium tetroxide or in Luft's potassium permanganate. After fixation in these two ways the general appearance is similar, but there are differences in certain tissue elements. Cell membranes are well preserved after fixation in KMnO4. Certain lipid inclusions in the cytopl...

Potassium permanganate (KMnO4) and oleic acid (OA) were purchased from Alfa Aesar. Glutathione (GSH), 3-(4,5-dimethylthialzol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), alpha lipoic acid (ALA), buthionine sulfoximine (BS) and N-ethylmaleimide (NEM) were purchased from Sigma-Aldrich. Doxorubicin hydrochloride (DOX) was purchased from Dingguo reagent company (Beijing, China). All buffers were p...

4-Allyl-4-hydroperoxy-2-methoxycyclohexa-2,5-dienone (5) was synthesized by photooxygenation of commercially available Eugenol in the presence of tetraphenylporphyrin (TPP) as a singlet oxygen sensitizer. The brief and one-pot syntheses of some natural product skeletons were conducted using the corresponding allylic hydroperoxide at different temperatures (0 o C and room temperature) with potas...
