Figure 1. Effect of nandrolone and low-intensity exercise on RBC indices, serum iron indices and grip strength. (A) Western analysis for splenic nuclear androgen receptor (AR) with histone3 (H3) as loading control; changes in (B) hemoglobin (C) RBC counts (D) hematocrits*; (E) serum iron, (F) serum transferrin saturation, (G) baseline grip strength, (H) changes in grip strength after two months of intervention. Results are means ± SE, between group comparison by t test. *The increase of Hct in parallel with a decrease in HgB may be explained by an age-related across board rise of MCV which changed from 43.35 ± 2.7 to 51.27 ± 2.2 (fl, means ± SD). The actual number of Hct are c: 35.33 ± 0.59 // 37.57 ± 1.37; ex: 34.24 ± 3.76 // 37.59 ± 4.10; n: 35.16 ± 4.48 // 39.80 ± 3.35; 30.65 ± 3.62 // 41.30 ± 3.95; with // denotes data obtained before and after the interventions.
