Regeneration of the tail of X-irradiated Xenopus tadpoles. 1977

M Ahmad, and F S Billett

The effects of X-rays on the regeneration of the tail of Xenopus laevis tadpoles have been studied. Larvae of stage 52 were exposed in groups to irradiation either of the head or the body region with doses of 3,000 and 4,000 r. In both cases, the animals have regenerated the lost parts of their tails.

UI	MeSH Term	Description	Entries
D011829	Radiation Dosage	The amount of radiation energy that is deposited in a unit mass of material, such as tissues of plants or animal. In RADIOTHERAPY, radiation dosage is expressed in gray units (Gy). In RADIOLOGIC HEALTH, the dosage is expressed by the product of absorbed dose (Gy) and quality factor (a function of linear energy transfer), and is called radiation dose equivalent in sievert units (Sv).

D012038	Regeneration	The physiological renewal, repair, or replacement of tissue.	Endogenous Regeneration,Regeneration, Endogenous,Regenerations
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.

D013623	Tail	An extension of the posterior of an animal body beyond the TORSO.	Tails
D014965	X-Rays	Penetrating electromagnetic radiation emitted when the inner orbital electrons of an atom are excited and release radiant energy. X-ray wavelengths range from 1 pm to 10 nm. Hard X-rays are the higher energy, shorter wavelength X-rays. Soft x-rays or Grenz rays are less energetic and longer in wavelength. The short wavelength end of the X-ray spectrum overlaps the GAMMA RAYS wavelength range. The distinction between gamma rays and X-rays is based on their radiation source.

D014981	Xenopus	An aquatic genus of the family, Pipidae, occurring in Africa and distinguished by having black horny claws on three inner hind toes.
