title: Failure of interleukin-2 to alter systolic blood pressure in Dahl salt-sensitive rats.
abstract: The effect of interleukin-2 (IL-2) on systolic blood pressure in Dahl salt-sensitive rats was investigated. The treatment group received human IL-2 injections (5000 units/kg). Control animals received subcutaneous saline injections. Both groups of animals were placed on a diet containing 1.5% sodium the day of the first injection and maintained on that diet for the duration of the study. Systolic blood pressure increased in both the IL-2 treated and the control groups (P = .0001) over 7 weeks. The increase in SBP was the same for both groups (P = .8823 for between group differences). At the end of 7 weeks, when SBP in both groups was elevated to a similar degree, the IL-2 group and the control group were each administered 5000 units/kg of IL-2. SBP in both groups remained elevated, showing no decrease over the next two weeks. These results indicate that perhaps unlike in SHR, IL-2 does not alter systolic blood pressure in Dahl salt-sensitive rats.
