A participation of biological and pharmacological components has also been discussed for thiols [5] and other substances (fatty compounds, estrogens, lipopolysaccharides) [6]. In this connection, the question of an effect of these substances on regulating and

Some General Aspects of Radioprotection (a Summary),cts, we refer (1) to paradoxical reactions that hint strongly at the underlying mechanism of action, (2) to the temporal dependence of protection and (3) to the fact that radioprotection must of necessity be viewed in connection with systemic relationships.

Mottram, for example, in the mid 30’s suggested that the skin could be protected in radiotherapy by limiting the blood supply by pressure or other means during irradiation [1–3]. In 1942, Lacassagne demonstrated a marked protec
