DURING an investigation of the toxic action of beryllium salts on experimental animals a histochemical test was developed to provide information on the distribution and site of action of beryllium. The technique is reported as an example of the application of chemical methods to histological problems. The reactions of beryllium salts with dyes of the triarylmethane series have been studied by A...

BACKGROUND Sevelamer hydrochloride is a recently approved calcium- and aluminium-free phosphate binder. A randomized study comparing sevelamer and calcium acetate was performed to assess the control of hyperphosphatemia in hemodialysis patients. METHODS Administration of phosphate binders was discontinued during a two-week washout period. The patients were then randomized to receive sevelamer...

The dialysis encephalopathy syndrome (DES) consists of altered mental status, communication difficulty, seizures and myoclonus. It has been attributed to elevated serum aluminium (A1) levels. Two undialysed patients with chronic renal failure who presented with the characteristic syndrome are reported. The first, a 48 year old female, had used A1 containing phosphate binders for two years. Her ...

The state of the electrochemical behaviour Al electrode in aqueous solutions containing Na2MoO4 + H3PO4 chitosan was investigated by methods currentless chronopotentiometry, chronoamperometry, optical and scanning electron microscopy. modification surface polymolybdate phosphate layers carried out a potentiostatic mode potentials range from ?1 to ?3 V polarization time (from 15 90 min). element...

pressure ulcers result from immobility and continuous pressure on an area of body. besides imposing further restriction of movements and thus creating a vicious circle in the healing process, these ulcers are of significant importance in decreasing the life quality and increasing the costs of treatment in these patients. in this study we compared the outcome of treatment of pressure ulcers with...

investigation of aluminium uptake by human erythrocytes was the major aim of this study. packed red blood cells were incubated in earle's medium (ph 7.4) containing varying concentrations of aluminium (0-160 /lg/j) as aik(so.), and aluminium content of the cells were determined using flameless atomic absorption. there was significant increase in aluminium content of the cells. addition of ...
