To examine the reported beneficial effect of zinc in rheumatoid arthritis, rheumatoid synovial tissue has been maintained in vitro in non-proliferative culture with or without zinc sulphate in the culture medium. Alkaline phosphatase activity was measured by microdensitometry of the cytochemical reaction in cryostat sections; the activity in blood vessels was measured separately from that in th...

the effects of bio-priming with different isolates of biological agent of trichoderma spp. and pseudomonas fluorescens on morphological and physiological characteristics of a bean cultivar (yaas) as well as their effects on controlling of rhizoctonia solani were investigated in two separate experiments. in the first experiment, different isolates of trichoderma including trichoderma harzianum b...

A double-blind controlled trial of oral zinc sulphate as adjuvant treatment in idiopathic ulcerative colitis or proctitis in relapse is reported. Fifty-one patients were treated, and the clinical and sigmoidoscopic improvement in the zinc treated patients was similar to that in patients receiving placebo. No difference was found between plasma zinc levels in a further 46 patients with idiopathi...

Zinc was electrodeposited from an acidic sulphate solution on commercial steel sheet substrates galvanostatically at 10, 20, and 100 mA/cm2. The steel substrates had an average roughness number of 1.34 microns and a high percentage of its grains had their (111) planes parallel to the plate surface. During electrodeposition at 10 mA/cm2, on some specimens, there was an intense potential fluctuat...

a complexometric method for the determination of titanium in the presence of other metal ions based on the selective masking ability of 5-sulphosalicylic acid towards titanium is described. titanium (iv) present in a given sample solution is complexed with a known excess of edta and surplus edta is titrated against zinc sulphate solution at ph 5-6 using xylenol orange as the indicator. a known ...

The effects of dietary zinc on zinc absorption and excretion were evaluated with six 12-week-old beagles. The dogs were fed a commercial dry food later supplemented with 2 and 4mg/kg of body weight per day of either zinc sulphate, zinc acetate or zinc oxide. The concentrations of zinc in the urine and faeces of all treatment groups were increased depending on the type of zinc salts and the dosa...
