title: Splenic function following experimental dearterialization injury in the suckling rat.
abstract: An experimental splenic dearterilization injury was created in 1-wk-old rats to study the effect of vascular trauma on splenic function. Splenic weight significantly decreased 1 wk following injury but returned to control values within a month. Total splenic nuclear activity diminished initially but increased to above control values 1 mo after injury, and finally returned to normal at 2 mo. Survival rate after an intraperitoneal challenge with pneumococcus in groups 1 wk following total splenectomy and partial dearterlization was not significantly different than controls. This study confirmed the clinical impression that vascular injury to the spleen causes only a transient impariment of splenic size and function and provides further incentive to perform splenorrhaphy following splenic trauma.
