Anti‐Aging Effects of Schisandrae chinensis Fructus Extract: Improvement of Insulin Sensitivity and Muscle Function in Aged Mice
Supplementation with SFe enhanced the grip strength and increased myofiber size of aged mice. (a) Grip strength. The data are the mean ± standard error (SE) (n = 11 per group). ; (b) H&E and PAS staining of TA muscle sections. Representative images are shown (×200) (n = 3 per group). (c) The cross-sectional area (CSA) distribution of muscle fiber was measured using ImageJ program, and the average CSA are shown (n = 3 per group). (d) The percentage of myofiber with central nuclei in TA muscle (n = 3 per group). (e) PAS-stained positive and negative myofibers were counted using ImageJ program, and the data are expressed as a percentage of the number of total myofibers. Data are presented as the mean ± standard error (SE) (n = 3 per group). Three different areas per sample were analyzed. ;; and .
