Simplified biopsy of the liver in dogs.

MANY of our research studies on dogs have required the repeated removal of large liver samples which must be processed immediately for biochemical or other studies. A simplified technique has been used. The tip of one of the lobes of the liver is gently grasped with a sponge (Fig. 1a). A 0 cotton ligature is placed as far back as is necessary to obtain the required size biopsy. The ligature is then tightened, partially amputating the specimen which is imme-
