Periarticular injection of Ad-mIL-4 into the hind leg ankle joints
conferred a therapeutic effect in the untreated, front paws. The arthritic mice
injected in the hind leg ankle joints with Ad-mIL-4, Ad-eGFP or saline were
evaluated for the severity of arthritis in either the hind, treated paws
(a) or front, untreated paws (b). The macroscopic score (mean
± standard deviation) is expressed as a cumulative value for the two paws,
with a maximum possible score of 8.
