BACKGROUND Using rat stomach perforation as a prototypic direct lesion applied in cytoprotection research,we focused on the first demonstration of the severe occlusion/occlusion-like syndrome induced by stomach perforation.The revealed stomachinduced occlusion/occlusion-like syndrome corresponds to the previously described occlusion/occlusion-like syndromes in rats suffering multicausal pathology and shared severe vascular and multiorgan failure.This general point was particularly reviewed.As in all the described occlusion/occlusion-like syndromes with permanent occlusion of major vessels,peripheral and central,and other similar noxious procedures that severely affect endothelium function,the stable gastric pentadecapeptide BPC 157 was resolving therapy.AIM To reveal the stomach perforation-induced general occlusion/occlusion-like syndrome and BPC 157 therapy effect.METHODS The procedure included deeply anesthetized rats,complete calvariectomy,laparotomy at 15 min thereafter,and stomach perforation to rapidly induce vascular and multiorgan failure occlusion/occlusion-like syndrome.At 5 min post-perforation time,rats received therapy[BPC 157(10μg or 10 ng/kg)or saline(5 mL/kg,1 mL/rat)(controls)]into the perforated defect in the stomach).Sacrifice was at 15 min or 60 min post-perforation time.Assessment(gross and microscopy;volume)included:Brain swelling,peripheral vessels(azygos vein,superior mesenteric vein,portal vein,inferior caval vein)and heart,other organs lesions(i.e.,stomach,defect closing or widening);superior sagittal sinus,and peripherally the portal vein,inferior caval vein,and abdominal aorta blood pressures and clots;electrocardiograms;and bleeding time from the perforation(s).RESULTS BPC 157 beneficial effects accord with those noted before in the healing of the perforated defect(raised vessel presentation;less bleeding,defect contraction)and occlusion/occlusion-like syndromes counteraction.BPC 157 therapy(into the perforated defect),induced immediate shrinking and contraction of the whole stomach(unlike considerable enlargement by saline application).Accordingly,BPC 157 therapy induced direct blood delivery via the azygos vein,and attenuated/eliminated the intracranial(superior sagittal sinus),portal and caval hypertension,and aortal hypotension.Thrombosis,peripherally(inferior caval vein,portal vein,abdominal aorta)and centrally(superior sagittal sinus)BPC 157 therapy markedly reduced/annihilated.Severe lesions in the brain(swelling,hemorrhage),heart(congestion and arrhythmias),lung(hemorrhage and congestion),and marked congestion in the liver,kidney,and gastrointestinal tract were markedly reduced.CONCLUSION We revealed stomach perforation as a severe occlusion/occlusion-like syndrome,peripherally and centrally,and rapid counteraction by BPC 157 therapy.Thereby,further BPC 157 therapy may be warranted. 展开更多

The stable gastric pentadecapeptide BPC 157 counteracts various venous occlusion-induced syndromes.Summarized are all these arguments,in the Robert’s cytoprotection concept terms,to substantiate the resolution of different major vessel occlusion disturbances,in particular ischemia-reperfusion injury following the Pringle maneuver and Budd-Chiari syndrome,which was obtained by BPC 157 therapy.Conceptually,there is new point(bypassed occluded or ruptured vessel,the equation endothelium maintenance→epithelium maintenance=blood vessel recruitment and activation towards defect or bypassing vessel occlusion),the recruitment of collateral blood vessels to compensate for vessel occlusion and reestablish blood flow.In this paper,we summarize the evidence of the native cytoprotective gastric pentadecapeptide BPC 157,which is stable in the human gastric juice,is a membrane stabilizer and counteracts gut-leaky syndrome.As a particular target,it is distinctive from the standard peptide growth factors,with particular molecular pathways involved,controlling VEGF and NO pathways.In the early 1990s,BPC 157 appeared as a late outbreak of the Robert’s and Szabo’s cytoprotection-organoprotection concept,epithelium,endothelium protection as previous theoretical/practical breakthrough in the 1980s,and brain-gut axis and gut-brain axis.As the time went on,with its reported effects,it is likely most useful theory practical implementation and justification.Meantime,several reviews suggest that BPC 157,which does not have a lethal dose(LD1),has profound cytoprotective activity,used to be demonstrated in ulcerative colitis and invented to multiple sclerosis trials.Likely,it may bring the theory to practical application,starting with the initial argument,no degradation in human gastric juice for more than 24 h,and thereby,the therapeutic effectiveness(including therapeutic per-oral regimen)and pleiotropic beneficial effects. 展开更多
