Immediate effect assessed blood vessels disappearance (obtained 0-5) in the belly surface immediately after anastomosis creation. RESULTS BPC 157 (all regimens) fully counteracted the perilous disease program from the very beginning (< 0.05 were considered statistically significant. RESULTS Esophagogastric anastomosis program In general, since the beginning, the rats that underwent esophagogastric anastomosis without medication suffered a very severe program (as assessed until post-operative day time 4) that would eventually become lethal (at post-operative day time 5). These rats experienced relatively small gastric lesions Zalcitabine (Number ?(Number1)1) compared with severe esophagitis lesions (Table ?(Table1)1) and poor anastomosis (constantly small water volume that may be sustained before leakage) (Number ?(Figure2).2). Considering the esophagus at the site of the anastomosis (Number ?(Number3)3) and pyloric sphincter (Number ?(Number4),4), the pyloric pressure seems to be more affected (constantly low pyloric sphincter pressure) than the esophageal pressure in the anastomotic site. The esophageal pressure was initially substantially lower that the lower esophageal pressure in normal rats; however, within the fourth day time, the esophageal pressure approached to that ideals. These changes, however, soon preceded the lethal end result on post-operative day time 5. In the mean time, these rats suffered considerable weight loss.
