title: [The evaluation of the sizes of erythrocytes of the hibernating ground squirrel Citellus undulatus Pallas].
abstract: A topographical image of individual erythrocytes of the ground squirrel Citellus undulatus Pallas, in unfixed unstained smears was first obtained by scanning probe microscopy for two states of the animal: hibernation and the active state. The scannig of single discocytes, i.e. erythrocytes having a typical discal form, was fulfilled. For the active male, the diameter of the discocyte was found to be approximately 6500 nm. For the hibernating female, the diameter is approximately 6000 nm. According to the data of light microscopy, the discocyte diameters are: 6610 +/- 100 nm for the active state of animal and 6430 +/- 160 nm for the hibernating state.
