Summary
-
1.
In rats and rabbits, clearing factor activation by heparin injections regularly undergoes a transient reduction after liver damage by carbon tetrachloride. In the rat, an increased activity (spontaneous as well as subsequent to heparin activation) follows in a later phase.
-
2.
In pregnant rats and rabbits, clearing factor activation is liable to be considerably reduced, although sometimes only temporarily. Normalization usually sets in several days before parturition.
-
3.
Rabbits treated with estradiol, progesterone, and gonadotropic hormone showed normal clearing factor activation.
-
4.
In some alloxan-diabetic rats and rabbits, reduction of clearing factor activation is observed.
