P < 0.01 vs. control of the respective sex, #
P < 0.05 vs male STZ. (B) Representative pictures of periodic acid Schiff-stained sections. Diabetic kidneys were characterized by moderate glomerulosclerosis, as evidenced by mesangial expansion (arrowheads), and is seen more abundantly in male STZ + GH than STZ alone.
