Abstract:
In view of the diversity of biological responses and the extent to which many of them remain poorly elucidated, there is merit in the suggestion by Calabrese and Baldwin that the term 'hormesis' should be applicable to those adaptive responses that are characterized by biphasic dose-response relationships, without reference to any associated beneficial or harmful effects. Whether the dose-response relationships for radiation-induced mutations and chromosome aberrations are biphasic in nature is an important question that remains to be resolved.

Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
