1. Nitric oxide that was produced by reducing nitrite with an excess of acidified potassium iodide under nitrogen in Warburg respirometer flasks was rapidly absorbed by a solution of permanganate in sodium hydroxide held in the side arm. A small amount of nitrous oxide (or nitrogen) that was also produced was not absorbed. 2. By using a quantitative method for the recovery of nitrite from sampl...

Attempted suicide by self poisoning is common because of the ready availability of drugs, whether prescribed or bought over the counter. In some cases, the ingestion of seemingly innocuous household products or chemicals can result in death. Potassium permanganate is an example. Poisoning with potassium permanganate can be fatal when a significant amount is ingested, as shown by a patient who s...

A morphological investigation of mitochondria within the seminal epithelial cells of rat testes fixed in potassium permanganate reveals differences in electron opacity between the internal mitochondrial membranes of spermatogenic cells and those of Sertoli cells. Some interpretations of the apparent density differences are briefly discussed. It is concluded that the different effects of permang...

a warm solution of potassium permanganate of strength 2 grains to the pint, in quantities of from 4 ozs. to one pint, three to four times a day. He further states '.... no one knows why potassium permanganate held in aqueous solution and injected into the rectum, should give such good results.' Since reading his article, and at the suggestion of Major J. M. R. Hennessy, i.m.s., Senior Medical O...
