Effects of an acute administration of nickel upon blood glucose compartmentation in pregnant rats.
The effects of a nickel injection i.p. to male, female virgin and 12- and 19-day pregnant rats upon plasma glucose concentration as well as blood cell free glucose content have been determined. The hyperglycaemic response to nickel of female rats was more marked than that of males, with an increase in intracellular glucose, more marked during pregnancy, which even surpassed the plasma concentration of glucose. Twelve-day pregnant rats maintained huge intracellular glucose concentrations even after the beginning of the decline in plasma levels, whereas this was not observed in 19-day pregnant rats. The possible rôle of the conceptuses in the removal of excess circulating glucose at this age is discussed.
