  2. This study included 5 Groups, namely, Group 1 (the sham procedure retina) as well as Groups 2, 3, 4 and 5 [(the retina subjected to ischemia plus reperfusion respectively pretreated with vehicle (I/R + vehicle), 2.8 g/kg/day of CJDHW (I/R + CJDHW2.8), 4.2 g/kg/day of CJDHW (I/R + CJDHW4.2) and SB203580 (p38 MAPK inhibitor)]
