White leghorn male chicks of 1 and 7 day age groups were studied for acute (2.25 Gy) gamma radiation (with or without vit. E pretreatment) induced haematological changes in the peripheral blood at days 1, 3, 5, 7, 14 and 28 postirradiation. A continuous decrease in the erythrocyte numbers was observed in the animals irradiated without vit. E treatment. The changes in haematocrit, haemoglobin, MCV, MCH and MCHC values were in line with the erythrocytic changes reflecting radiation induced damage to the erythroid elements. Animals pretreated with vit. E show lesser depression in the erythrocytic component at all the stages indicating its radio-protective influence. The significant increase in the immature RBC's in the peripheral blood in vit. E treated animals after irradiation, implies enhanced erythropoiesis.

D005720 Gamma Rays Penetrating, high-energy electromagnetic radiation emitted from atomic nuclei during NUCLEAR DECAY. The range of wavelengths of emitted radiation is between 0.1 - 100 pm which overlaps the shorter, more energetic hard X-RAYS wavelengths. The distinction between gamma rays and X-rays is based on their radiation source.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D014810 Vitamin E A generic descriptor for all TOCOPHEROLS and TOCOTRIENOLS that exhibit ALPHA-TOCOPHEROL activity. By virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus, these compounds exhibit varying degree of antioxidant activity, depending on the site and number of methyl groups and the type of ISOPRENOIDS.
