[Effect of electrolytes, components of peritoneal dialysis fluid, on the stability of glucose].

Dependence of stability of glucose upon electrolyte composition of solutions used for peritoneal dialysis was studied. Stability of glucose was estimated by determinations of formed 5-HMF. It has been stated that stability of glucose depends on the kind of electrolytes present in the solution, glucose concentration and conditions of thermal sterilization. The highest levels of 5-HMF were found in glucose solutions containing sodium acetate and sodium chloride, while glucose proved more stabile in solutions containing calcium chloride and magnesium chloride.

Contact sensitivity to trivalent chromium compounds.

The investigations confirmed the known fact that for skin tests larger amounts of trivalent chromium compounds are necessary than those of potassium dichromate. It was also observed that some patients react to relatively higher Cr VI and lower Cr III concentrations and others vice versa. Chromium nitrate and chloride release and that of potassium dichromate was determined and converted to the chromium content in the concentrations used for skin tests. It was found that Cr III compounds cannot be used for skin tests in a 0,5% concentration if only because they are released in undeterminable amounts. Release of Cr III and potassium dichromate from bases containing the same amount of substance when converted to chromium demonstrated that the different release of Cr III is not an additional cause of the fact that much higher concentrations of Cr III compounds have to be used for patch tests than those of Cr VI compounds.
