Sažetak
With intra(per)-oral strong alcohol application at the tongue, swallowed, we renewed Robert's stomach cytoprotection/adaptive cytoprotection concept. We assessed strong (96%) alcohol- induced severe or minute lesions in stomach, tongue-esophagus-stomach-duodenum lesions, and sphincter pressure (lower esophageal and pyloric) upon administration intragastrically (at 1 h) or intra(per)-orally at the tongue, and swallowed (at 1, 5, 15, 30 min ; and 1, 2, 24 h). The assessment also included combined administrations (intra(per)-oral at the tongue, swallowed and intragastric (at 1 h)). Immediate post-alcohol intraperitoneal medication (mg/kg) was the stable gastric pentadecapeptide BPC 157 (0.01, 0.00001 ; a Robert's cytoprotection mediator ; with a therapeutic effect), NOS- blocker L-NAME (5), and NOS-substrate L- arginine (100 mg), (NO-system involvement). After intragastric strong alcohol administration, severe stomach ulcerations appeared along with widespread tongue, esophagus, duodenum redness, and minimal sphincter pressures. By contrast, a particular syndrome (immediate overlapping of cytoprotection/adaptive cytoprotection) (minute gastric lesion or largely attenuated hemorrhagic ulceration, tongue affected, minute esophageal and duodenal lesions, but with intact mucosa ; sphincters pressures lowered) appeared after intra(per)-oral administration (1 min-24 h) as well as after combined administrations (intra(per)-oral + intragastric). BPC 157 apparently cured all alcohol-lesions, amplified the spontaneously initiated strong mucosal beneficial effect, rescued sphincter pressures ; NO-agents (L- arginine (slight mucosal amelioration) and L- NAME (aggravation)) showed NO-system involvement, but no comparable effects on dropped sphincters pressures. In conclusion, minute gastric lesions (with oral application of strong alcohol at the tongue and swallowed, without, or with intragastric application of strong alcohol) renew and revise Robert's stomach cytoprotection/adaptive cytoprotection concept. The tongue becomes a new initial target, resulting in spontaneous reversal of strong alcohol-stomach lesions. BPC 157 therapy functions also within the redirected complexity of Robert's stomach cytoprotection/adaptive cytoprotection concept.
