Fig. 1. Changes in the experimental animals’ body weight by groups before and after the experiment. 1, 2 — groups of males and females, which underwent BCP implantation, n = 12; 3, 4 — groups of males and females, which received subcutaneous injection of saline, n = 12. * — significant intragroup differences, p < 0.05
