Abdominal aorta anastomosis in rats and stable gastric pentadecapeptide BPC 157, prophylaxis and therapy.

We focused on abdominal aorta, clamped and transected bellow renal arteries, and aortic termino-terminal anastomosis created in Albino male rats. We suggested stomach cytoprotection theory holding endothelium protection and peptidergic anti-ulcer cytoprotection therapy to improve management of abdominal aorta anastomosis and thrombus formation. The stable gastric pentadecapeptide BPC 157 (GEPPPGKPADDAGLV, MW 1419) is a small anti-ulcer peptide efficient in inflammatory bowel disease trials (PL 14736) and various wound treatment, no toxicity reported. After 24 h following aortic termino-terminal anastomosis, we shown that BPC 157 (10 microg/kg) may also decrease formation of cloth after aortic termino-terminal anastomosis and preserved walking ability and muscle strength when given as a bath immediately after aortic anastomosis creation. This may be important since aortic termino-terminal anastomosis is normally presenting in rats with a formed cloth obstructing more than third of aortic lumen, severely impaired walking ability, painful screaming and weak muscle strength. Thereby, the effect of BPC 157 (10 microg/kg) was additionally studied at 24 h following aortic termino-terminal anastomosis. Given at the that point, intraperitoneally, within 3 minutes post-application interval the pentadecapeptide BPC 157 rapidly recovered the function of lower limbs and muscle strength while no cloth could be seen in those rats at the anastomosis site.
