The effect of the rat-cyclophosphamide serum on the rat hematopoietic tissue recovery, previously damaged by cyclophosphamide or by gamma-irradiation.

The effect of post-cyclophosphamide serum (post-CY serum) humoral activity in vivo, on the rat hematopoietic regeneration after damage either by cyclophosphamide (CY) or by gamma-irradiation was investigated. Three experimental groups of rats were studied. The first group was treated by a single high dose of CY (200 mg/kg), the second group was whole body irradiated by 6.
