ACCELERATED RECOVERY OF 5-FLUOROURACIL-DAMAGED BONE MARROW AFTER OXYTOCIN TREATMENT

Oxytocin, Myeloprotective, Medium size cells, 5-FluorouracilAbstract
Our preliminary data indicate that Oxytocin may be myeloprotective. We investigated whether it can modify bone marrow recovery. Oxytocin (150 µg/kg) accelerated the recovery of the number of medium size cells (MI%) and platelets (PLT) but did not affect the number of circulating red blood cells (RBC) and total count of white blood cells (WBC).Oxytocin injected subcutaneously for 5 consecutive days at doses of 150 µg/kg (twice a day) after 5-FU single dose. Glutathione GSH (anti-oxidant) has preventive effects against 5-FU-induced myelosuppression and can accelerate recovery of bone marrow. Oxytocin only increase GSH levels insignificantly (P > 0.05).These findings suggest that Oxytocinselectively enhances the recovery of the population of progenitor cells reduced by 5-FU in rats.
