Sažetak
We focused on the therapeutic effect of the stable gastric pentadecapeptide BPC 157 and how its action is related to nitric oxide (NO) in persistent colocutaneous fistula in rats (at 5 cm from anus, colon defect of 5 mm, skin defect of 5 mm) ; this peptide has been shown to be safe in clinical trials for inflammatory bowel disease (PL14736) and safe for intestinal anstomosis therapy. BPC 157 (10 μ g/kg, 10 ng/kg) was applied i) in drinking water until the animals were sacrificed at post-operative day 1, 3, 5, 7, 14, 21, and 28 ; or ii) once daily intraperitoneally (first application 30 min following surgery, last 24 h before sacrifice) alone or with NG-nitro-L-arginine methyl ester (L-NAME) (5 mg/kg), L-arginine (200 mg/kg), and their combinations. Sulphasalazine (50 mg/kg) and 6-α -methylprednisolone (1 mg/kg) were given once daily intraperitoneally. BPC 157 accelerated parenterally or perorally the healing of colonic and skin defect, leading to the suitable closure of the fistula, macro/microscopically, biomechanically, and functionally (larger water volume sustained without fistula leaking). L-NAME aggravated the healing failure of colocutaneous fistulas, skin, and colon wounds (L-NAME groups). L-Arginine was effective only with blunted NO generation (L-NAME + L-arginine groups) but not without (L-arginine groups). All of the BPC 157 beneficial effects remained unchanged with blunted NO-generation (L-NAME + BPC 157 groups) and with NO substrate (L-arginine + BPC 157 groups) as well as L-NAME and L-arginine co-administration (L-NAME + L-arginine + BPC 157 groups). Sulphasalazine was only moderately effective, and corticosteroid even had an aggravating effect.
