Estimation of barium sulphate in faeces by emission flame photometry.
Received for publication 12 July 1968. ashed in a muffle furnace at 600'C for at least three hours. Of the acid ammonium sulphate, 10 ml, and 30 ml of water are added to the ashed sample, and after warming to dissolve soluble material the contents are decanted with washing into a 50 ml centrifuge tube, the BaSO4 being washed into the tube as far as possible. The tube is centrifuged for 5 min, t...
متن کاملBarium Sulphate Absorption and the Serum Diagnosis of Syphilis
The so-called syphilitic antibodies can be removed from a serum by means of absorption with barium sulphate. The removal is due either to an adsorption or a mechanical absorption. The activity of the syphilitic antibodies is thereby unimpaired. The readiness with which the absorption is accomplished with barium sulphate varies considerably with different syphilitic sera. That barium sulphate ex...
متن کاملEffect of Absorbability of Iron Contents by Precipitated Barium Sulphate in the Commercial Crude Sodium Sulphide
The paper presents the investigations on absorbability of ferri/ferrous impurities found in commercial grade sodium sulphide. The later product is unsuitable for the manufacture of pharmaceutical grade chemicals and dyes chemicals.The author have carried out experiments on the use of precipated barium sulphate as an adsorbent in different propotions in the aqueous solution of commercial grade s...
متن کاملVaried light and scanning electron microscopic appearances of barium sulphate in smears and histological sections.
The various light and scanning electron microscopic appearances of barium sulphate in smears and in histopathological lesions in sections are illustrated. One type of barium sulphate (E-Z-HD) includes much larger, bright birefringent particles and has very different appearances from other widely used types. Such larger particles in sections were not originally suspected to be barium sulphate an...

gradient-gel electrophoresis [5] with scanning using the BioRad Model 620 Video Densitometer. On day 1, the alcoholic patients had, in general, concentrations of HDL that were markedly higher [ 11 1.7 f 32.0 mg/100 ml ( m e a n f s . ~ . ) ; range 65.0-136.8 mg/100 ml] than control subjects (61.7k 11.0 mg/100 ml; range 45.7-71.1 mg/100 ml), but which fell (P<0.01) to within the normal range bet...
