Sir, Sandhu et al.1 showed convincingly that oral rehydration with a glucose-polymer solution (12.5 g/100 ml, giving 730 mmol/l glucose) and 90 mmol/l sodium predisposes to hypernatraemia. In so doing they reproduced the circumstances that contributed to the epidemic of hyper-natraemia in the 1950s.2 At that time commercial oral rehydration solutions were changed to high concentrations of gluco...

polypyrrole (ppy/cl) and polyaniline (pani/cl) synthesized chemically onto sawdust (sd)was used for removal of thiocyanate (scn-) ions from aqueous solutions. the effect of someimportant parameters such as ph, initial concentration, sorbent dosage, and contact time onuptake of scn- was investigated. ppy/sd was found to be much more effective sorbent thanpani/sd for uptake scn- from aqueous solu...

P olyethylene Glycol-Electrolyte Lavage Solution (PEG-ELS), “Golytely,” has been available since the early 1980s. Davis et al, developed it as a safer alternative for traditional bowel cleansing using balanced electrolyte solution. It provides rapid cleansing of the bowel with only minimal transmucosal movement of water or sodium (1). Polyethylene Glycol (PEG) is a linear polymer made up of rep...
