[Changes in the transaldolase activity in the liver, spleen and bone marrow of rats after total X-ray irradiation]. / Izmenenie aktvnosti transal'dolazy v pecheni, selezenke i kostnom mozge krys posle total'nogo rentgenovskogo oblucheniia.

The paper deals with changes in the activity of transaldolase in tissues of the liver, spleen and bone marrow of rats 4.24 h and on the 3 d, 7th, 18th, 30th, 45th, and 60th day after total X-ray irradiation in a dose of 600 R. The ionizing irradiation causes a stable inhibition of the enzyme activity in All tissues. The observed changes are homogeneous in their direction but have their own peculiarities for each tissue. Differences in the degree and extent of the enzyme activity changes at various stages of the X-ray lesion development in the tissues under study may be explained by their different sensitivity to the penetrating radiation.
