Data presented as mean ± SD. Body weight (BW), systolic blood pressure (SBP), and plasma level of IL-1β were measured at before (10 weeks of age) and every one week of IL-1β administration. Food intake (Intake) is presented as the mean weight of food eaten per day during each week. * , ** , *** versus Control by unpaired Student -test. in each group.
