Radioprotective Effects of Prostaglandins for Chromosomal Aberrations and Cell Killing in V79 Chinese Hamster Cells Grown as Spheroidsin Vitroand for Mouse Spermatogonial Stem Cells and Bone Marrow Cellsin Vivo

Abstract
The radioprotective effects of prostaglandins (PGE2, PGE1 and its analogue misoprostol (MP) were investigated in cultures of V79 Chinese hamster (CHO) cells grown as spheroids and as monolayers, CHO cells grown as monolayers, and in bone marrow polychromatic erythrocytes and spermatogonial stem cells in mouse. The X-ray doses were 0·75 Gy (hamster cells) and 5, 8 and 10 Gy (mouse experiments).
