Effects of splenectomy on platelet levels during hibernation. Ground squirrels received either a splenectomy or sham surgery during the summer. Blood samples were collected pre-and post-surgery samples, upon entrance into hibernation and during an IBA, and platelets counted on a Hemavet. During torpor, blood smears were collected without waking the animal and counted manually. N= 10 animals, analyzed by student t-test, bars with different letters were significantly different, p<0.05.
