Rats with the disabled myotendinous junction, functional tests (motor functional index (MFI) (upper) (a), walking recovery index (WRI), mm (lower) (b), means ± SD) at 1, 3, 5, 7, 10, 14, 21, 28 and 42 days. Higher MFI and WRI values signify higher failure; higher MFI signifies more muscle function failure; higher WRI signifies more walking function failure. Medication (BPC 157 (10 µg/kg, 10 ng/kg)) was applied either intraperitoneally (BPC 157 µg i.p.; BPC 157 ng i.p.), first application immediately after surgery, last 24 h before sacrifice, or perorally in drinking water (0.16 µg/mL, 0.16 ng/mL, 12 mL/rat/day) (BPC 157µg po; BPC 157 ng po) while controls received either saline (5 mL/kg) intraperitoneally or drinking water (12 mL/rat/day) till the sacrifice, at 7, 14, 28 and 42 postoperative days.* p < 0.05, at least, vs. control(ip); x p < 0.05, at least, vs. control (po).
