Cytogenetic effects of60Co gamma radiation onBiomphalaria glabrata(Say, 1818) embryos

Effects of gamma-radiation on ovarian follicles.

In order to observe the morphological and endocrinological changes of the rat and mouse ovarian follicles by gamma-radiation, rats were whole-body irradiated with doses of 3.2 Gy and 8.0 Gy and mice with 2.9 Gy and 7.2 Gy. Sections of ovaria were examined by light microscopy. Concentrations of progesterone, testosterone, and estradiol in ovarian homogenate were determined by radioimmunoassay te...

Gamma Radiation Effects on Peanut Skin Antioxidants

Peanut skin, which is removed in the peanut blanching process, is rich in bioactive compounds with antioxidant properties. The aims of this study were to measure bioactive compounds in peanut skins and evaluate the effect of gamma radiation on their antioxidant activity. Peanut skin samples were treated with 0.0, 5.0, 7.5, or 10.0 kGy gamma rays. Total phenolics, condensed tannins, total flavon...

Genetic Susceptibility to Radiation Effects in Early Embryos

It has been known for a long time that the tissues in intense proliferation, i.e. those containing many dividing cells, are particularly radiosensitive. This is the law formulated as early as in 1906 by Bergonié and Tribondeau, after which the radiosensitivity of a tissue increases as its cells are less differentiated, have a greater potential of proliferation and divide more rapidly. Therefore...

X-Radiation and Gamma Radiation

Ionizing radiation is electromagnetic radiation that has sufficient energy to remove electrons from atoms. Ionization results in the production of negatively charged free electrons and positively charged ionized atoms. Ionizing radiation can be classified into two categories: photons (X-radiation and gamma radiation) and particles (alpha and beta particles and neutrons). Five types or sources o...
