Figure 3From: Aging enhances serum cytokine response but not task-induced grip strength declines in a rat model of work-related musculoskeletal disorders Two serum cytokines and chemokines, IFN-γ (A) and MIP 2 (B) increased in young 6-week HRLF rats, compared to young normal control rats (NC). This increase was absent in young 12-week HRLF rats. Mean + SEM shown. ap < 0.05 compared to young normal control (NC) rats; bp < 0.01 compared to young 12-week HRLF rats.Back to article page
