[The effect of space flight factors on the peripheral blood in the newt Pleurodeles waltlii].

The effects of space flight factors (SFF) on the peripheral blood in Pleurodeles waltlii were assessed after 12-day flight on board of the biosatellite "Kosmos-2229". These animals were also used to study regeneration of the limb, tail and lens. The corresponding control groups of animals allowed to distinguish between the effects of the operation, non-specific and specific SFFs: (1) basal control-operated animals; (2) synchronous control-operated animals kept on the Earth under the same conditions as the flight group, and (3) intact animals.
