With dimethyl sulphoxide instead of butanol in the thiobarbituric acid assay for sialic acid, a non-fading chromophore with lambdamax. = 549 nm was produced in a homogeneous solution, allowing dilution of the test mixture in case of high colour yield. This test adapted well to studies on alkaline de-O-acetylation. Bovine and rat submaxillary mucins, and rabbit Tamm-Horsfall urinary sialoprotein...

Alkaline hydrolysis has been used in several laboratory studies and field demonstrations for the treatment of energetic compounds (particularly, 2,4,6-trinitrotoluene (TNT), dinitrotoluene (DNT), and hexahydro-1,3,5trinitro-1,3,5-triazine (RDX)) in soil. The application of alkaline hydrolysis for treatment of soil involves mixing a caustic source material with soil. Two caustic materials have b...

The South African gold mining industry has a legacy of abundant tailings dams, which have attracted the attention investors because their potential as cheaper secondary resource. In this we investigate study recovery from refractory calcine dam. Bulk mineralogy indicated silicates and iron oxides to be most phases. Scanning Electron Microscopy (SEM) showed exist in submicrometre micrometre size...

Acute intoxication with 2,4-D dimethylamine is rare, often fatal and can cause signs symptoms in different organ systems. This case report describes the effectiveness of alkaline diuresis as a life-saving treatment for chlorophenoxy intoxication, especially healthcare facilities without access to haemodialysis. A patient had attempted suicide by ingesting dimethylamine, toxic effects on central...

Two patients are presented in whom extensive investigations were carried out to determine the cause of a raised serum alkaline phosphatase. Idiopathic retroperitoneal fibrosis was diagnosed in both cases and the serum alkaline phosphatase returned to normal following treatment with corticosteroids and coincident with resolution of the patients' symptoms.
