Abstract Enzymatic (glucose oxidase) measurement of glucose concentration in the fluid compartment of Psammomys erythrocytes (Gfe) and of its concentration in the fluid compartment of blood plasma (Gfp) gives the ratio (mean +/- SD): Gfe/Gfp = 1.50 +/- 0.43 (n = 12, 23 degrees C). However, when we added 3H-labeled glucose (G*) in vitro to the whole blood, the ratio after 2 min was G*fe/G*fp = 0.90 (SD 0.11) and after 5 min G*fe/G*fp = 0.97 (SD 0.12). These calculations were based on previous determination of the fractional volumes of the fluid and non-fluid compartments in Psammomys blood. The results suggest that there is more than one compartment of measurable glucose in Psammomys erythrocytes. Glucose undergoes a fast free transfer between the plasma and the erythrocyte fluids, and a much slower transmission to another measurable compartment in the erythrocyte, where it is loosely bound to other molecules. This loosely bound glucose does not participate in the fast kinetic transmission across the erythrocyte membrane, but it is measurable by the glucose-oxidase-based method. Preliminary studies on human erythrocytes lead to similar conclusions.

Laboratory Colony

The lifespan and fertility of albino sand rats were found to be severely reduced in comparison with a laboratory colony of brown sand rats. The albinos were also much more susceptible to diabetes, as judged by their glucose tolerance. In fact, untreated albinos had a higher incidence of diabetic response than coloured sand rats fed a diabetogenic diet. The albino sand rats reproduced poorly because of a reduction in male fertility. Circulating testosterone levels and seminal vesicle weights were reduced in the albinos. It is speculated that the reduction in reproductive capacity is related to diabetes.
