The molecular weight of the major glycoprotein from the human erythrocyte membrane is 29,000, of which 55% is carbohydrate and 45% is protein. The binding of sodium dodecyl sulfate to this glycoprotein is anomalous when compared to water soluble proteins and leads to migration rates in sodium dodecyl sulfate-polyacrylamide gels that cannot be interpreted in terms of molecular weight. Anomalous ...

In this work, the dissolution-absorption studies were conducted on marketed tablets of acyclovir (ACIVIR-200mg) and the mucoadhesive tablets of acyclovir using varying concentration of sodium lauryl sulfate as a permeation enhancer. The purpose of this study was to improve the absorption of acyclovir using sodium lauryl sulfate as permeation enhancer. The everted and perfused intestine model wa...

The use of sodium sulfate instead of ammonium sulfate in the precipitation of globulins makes it possible to determine the proteins of plasma or serum in small quantities of ‘blood. The basis for the selection of sodium sulfate has been discussed in the preceding paper (1). Robertson (2) described a procedure for the determination of blood proteins in small quantities of blood with the aid of t...

The polyelectrolyte nature of chondroitin sulfate and related polysaccharides suggests they may bind cations. Since chondroitin sulfate is an extracellular component of mammalian connective tissue, the binding properties of this polyelectrolyte for cations may be of significance in the distribution and storage of extracellular cations. In disease states in which sodium is known to play a major ...

in this study, oxidation of some 3,5-diacyl or 3,5-diester 1,4-dihydropyridines to corresponding pyridine derivatives using sodium bromate in the presence of nh4cl, nahso4 and bu4nhso4 under thermal conditions has been investigated. the yield and structure of formed products is similar under all conditions; however, the reaction is accelerated in the presence of bu4nhso4 and nahso4. in addition...

The adsorption, micelle formation, and salting out of sodium dodecyl sulfate in the presence of sodium chloride were studied from the viewpoint of their mixed adsorption and aggregate formation. The surface tension of aqueous solutions of a sodium chloride-sodium dodecyl sulfate mixture was measured as a function of the total molality and composition of the mixture. Phase diagrams of adsorption...

organophosphorous (op) chemical warfare nerve agents mainly sarin and tabun were used during the iran-iraq war with high mortalities. in addition to atropine and oximes, the followings have recently been used successfully for the treatment of op poisoning. 1. sodium bicarbonate: infusion of high doses of sodium bicarbonate (5 meq/kg in 60 min. followed by 5-6 meq/kg/day to obtain arterial blood...
