This animal model study investigated the effects of BPC 157, a synthetic gastric pentadecapeptide, on tissue reperfusion outcomes in rats subjected to maintained intra-abdominal hypertension (Grade III and IV). The researchers found that BPC 157 administration improved reperfusion parameters and reduced tissue damage following the hypertensive insult compared to control animals. **Evidence level: Animal model** (Note: The source metadata indicates “Human Clinical,” but the study design and methods described are rat-based research, making this an animal model study rather than human clinical evidence.)
