Summary

The effects of 2 intraperitoneal injections of the alkylating agent Busulphan (each of 25 mg/kg body weight, 3 days between injections) on the circulating elements of the blood and on the plasma coagulation system in rabbits have been investigated.

Platelets fell progressively after a lag-phase of 7 days, reached a mean minimum level of about 3 % of the pre-injection level in 14 days, and then returned slowly towards normal values. Bleeding was an occasional complication and a rare cause of death. Granulocytopenia developed synchronously with the fall in platelets. The plasma clotting factors remained intact.

We conclude that this is a useful experimental model for studies on the role of platelets in hemostasis and thrombosis.
