[The development of neurocytes of the arcuate nucleus of the hypothalamus following whole-body gamma-irradiation of newborn rats]. 1990

V I Dedov

The results of karyometric and cytometric studies show that gamma-irradiation inhibits the growth and development of arcuate nucleus neurocytes of hypothalamus. The secretory function of neurocytes is also inhibited which is particularly important with regard to the formation of adenohypophysis functions as a major regulator of the adaptation response development. A radiation-induced disturbance of the latter aggravates the radiation injury to critical organs or systems of young animals thus influencing their viability.

D003037	Cobalt Radioisotopes	Unstable isotopes of cobalt that decay or disintegrate emitting radiation. Co atoms with atomic weights of 54-64, except 59, are radioactive cobalt isotopes.	Radioisotopes, Cobalt
D005260	Female		Females
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.
