چکیده

The manometric study of biological oxidations by the “direct method” of Warburg, when carried out in the presence of cyanide, involves the use of KOH-KCN mixtures (Krebs (4)) for the absorption of carbon dioxide. The following study describes the rate of distillation of HCN from the experimental solution under various conditions, and suggests a remedy for the difficulties occasionally encountered (Machlis (2)) with the above mixtures.

One Pot Synthesis of Alpha-Aminonitrile and Alpha-Amino Acid From Schiff Bases

Addition of Potassium cyanide to a mixture of Schiff base and lithium perchlorate afforded a-aminonitriles in high yields. Addition of potassium cyanide to a methanolic solution of Schiff base and phosphoric acid afforded a-aminonitriles. When the reaction mixture was refluxed it gave a-amino acids in high yields.

Evaluation of some Enzymatic Changes in the Liver and Kidney of Rats Following Exposure to Sublethal Concentration of Potassium Cyanide

Background: Besides acute lethal cyanide poisoning, its chronic intoxication may also produce some pathologic effects on different tissues that precedes alterations in biochemical parameters. The present study was aimed to evaluate the effects of sublethal cyanide exposure on some tissue enzyme activities in liver and kidney of rats. Methods: Twelve male rats were divided into two groups as ...

Factors That Influence the Passage of Ascorbic Acid from Serum to Cells in Human Blood.

Ascorbi acid in serum was determined by the method of Mindlin and Butler (2) with the following modifications. (1) Neither potassium oxalate nor potassium cyanide was used. An anticoagulant was not necessary because the blood was defibrinated by stirring with a glass rod. The possible erroneous influence of added KCN has been demonstrated by other observers (3, 4, 5), as well as in this laborat...

A New Mixture of Nano-structure of Potassium-incorporated Hydroxyapatite/β-tricalcium Phosphate/calcium Pyrophosphate

The new triphasic potassium−substituted hydroxyapatite (KHAP), β−tricalcium phosphate (β−TCP), and calcium pyrophosphate (CPP) proportions using easy sol−gel method were synthesized. The prepared powders was characterized by X–ray diffraction (XRD), Fourier transform infrared (FTIR), Differential thermal behavior (DTA) analysis, Energy Dispersive X–ray Analysis (EDXA), and Brunauer–Emmett–Telle...
