background: strontium, zinc, and potassium salts have been demonstrated to inhibit irritation and infl ammation when applied topically. particularly, strontium chloride (sc) and potassium nitrate (kn) are reported to reduce skin and tooth sensitivity.the aim of the present study was to compare the anti-irritant eff ects of four inorganic salts and assign the ingredient which can suppress skin i...

UNLABELLED To clinically evaluate the effectiveness of Nite White 10% carbamide peroxide with amorphous calcium phosphate, potassium nitrate and fluoride over a 6-month follow-up period. Nite White was applied nightly for 14 days, according to the manufacturer's instructions. The color of teeth 11 and 21 of twenty one subjects was measured with a spectrophotometer (L(*); a(*); b(*)). Subjects w...

This study aimed to analyze the ecotoxicity of nitrogen-, phosphorus-, and potassium-based compounds to organisms of two different trophic levels in order to compare the toxic effect between high-purity substances and these substances as components of fertilizers. Dilutions were made with the fertilizers' potassium chloride, potassium nitrate, superphosphate, urea, and their equivalent reagents...

A new species of Candida was isolated from sphagnum litter overlying a peat bog. It was non-fermenting and assimilated glucose, sucrose, maltose, lactose, galactose and potassium nitrate. The proposed name is Candida mmcorum. A new Rhodotorula species, which i t is proposed to name R. graminis, was isolated from the leaves of pasture grasses. Cultures on solid media were reddish pink and fluid ...

considering the positive effects of silicon on salinity resistance by some agricultural plants, an investigation was conducted with a completely randomized design of three replications. the main objective was to determine the effect of silicon on nutrient content and nitrate accumulation in lettuce. electrical conductivity was adjusted at 3 mmhos/cm through addition of nacl. silicon was added t...

Roots of decapitated maize seedlings (Zea mays L.) were exposed for 12 hours to 1.0 millimolar KNO(3) (98.5 atom per cent (15)N) in the presence and absence (control) of 0.1 millimolar p-fluorophenylalanine (FPA), an analog of the amino acid phenylalanine. FPA decreased nitrate uptake but had little effect on potassium uptake. In contrast, accumulation of both ions in the xylem exudate was grea...
