background it has been shown that topical nanoliposomal formulations improve burn healing process. on the other hand, it has been shown that liposomal formulations increase drug deposition in the normal skin while decrease their systemic absorption there is not such data available for burn eschar. present investigation studies permeation of clindamycin phosphate (cp) through burn eschar from li...

In this paper, tetragonal chalcopyrite (CIGS) Cu(InxGa1-x)Se2 with x=0, 0.5, 0.8, 1 are synthesized by heating-up method. These nanoparticle structures differ in morphology and absorption properties due to the synthesis temperatures of 250, 255, 260, 265, 270 and 280 ºC, and gallium molar ratio over the total gallium and indium contents. These features are studied using scanning electron m...

The effect of a new complex oligosaccharide exhibiting potent inhibitory action on alpha-glucoside hydrolases on intestinal absorption of sucrose in man was tested by constant in vivo perfusion of the jejunum. At concentrations of 4.65 or 15.5 X 10(-6)M the alpha-glucosidehydrolase inhibitor (alpha-GHI) markedly inhibited absorption of glucose from sucrose and absorption of sodium and water. Or...

The cause or causes of hypercalcemia and hypercalcuria in sarcoidosis are obscure. Harrell and Fisher (1) were the first to emphasize that hypercalcemia, hyperproteinemia and elevated serum alkaline phosphatase could occur in this disease. Dent etat (2) believed that bone destruction represented the cause of hypercalcemia. Anderson et at (3) concluded from their studies that increased calcium a...

Experimental apparatus and measurement technique are described for precision absorption measurements in sodium-noble gas mixtures. The absolute absorption coefficient is measured in the wavelength range from 425 nm to 760 nm with ±2% uncertainty and spectral resolution of 0.02 nm. The precision is achieved by using a specially designed absorption cell with an accurately defined absorption path ...

Studies in intact animals have shown that intestinal solute absorption is enhanced with increasing flow rates; the mechanism of this phenomenon has not been explored in detail. We used single pass perfusions of rat ileum to study the effect of higher flow rate on electrolyte absorption. Augmenting perfusion rate from 0.5 to 5.0 ml/min resulted in increased rates of sodium (11.0 +/- 0.9 vs. 23.5...

1. Strontium absorption was studied in vivo with loops of ileum in rachitic chicks and found to be increased by vitamin D(3), bile salts and sodium lauryl sulphate. 2. Bile salts and sodium lauryl sulphate rendered strontium soluble in butanol-benzene (1:1, v/v). 3. Bile was not concerned in the absorption of iron in rats from its water-soluble form, ferrous sulphate. 4. Ligation of the bile du...

Salt-sensitive hypertension is common in people of African origin, and may be caused by increased transepithelial sodium absorption. The pH of nasal secretions is negatively correlated with the difference in Na(+) concentration between nasal secretions and plasma, and may be a marker of transepithelial sodium absorption. Nasal pH was measured using a probe sited under the inferior turbinate. Me...
