Fig 1. DEX reduced IR-induced renal tubular cell death in diabetic rats, TUNEL X40.

High-dose DEX treatments (20, 50, and 100 μg/kg) did not reduce apoptosis (A). DEX (10 μg/kg) reduced apoptosis (B). DEX²⁰, DEX⁵⁰, and DEX¹⁰⁰ correspond to DEX treatments at doses of 20, 50, and 100 μg/kg, respectively; *p < 0.05, compared with D-sham baseline; †p < 0.05, compared with D-IRC group; ‡p < 0.05, compared with DEX pre-treatment group.
