Esophagogastric anastomosis in rats: Improved healing by BPC 157 and L-arginine, aggravated by L-NAME.

BPC 157 administration fully prevented mortality and improved healing outcomes after esophagogastric anastomosis in rats. It counteracted the negative effects of L-NAME, a nitric oxide synthase blocker, and enhanced the beneficial effects of L-arginine, a nitric oxide precursor, indicating that BPC 157 acts via modulation of the NO system to promote tissue repair.

Rats underwent esophagogastric anastomosis surgery and were treated daily with intraperitoneal doses of BPC 157 (10 μg or 10 ng/kg), L-NAME (5 mg/kg), L-arginine (100 mg/kg), or combinations thereof for 4 days. Healing was assessed by measuring stomach damage, esophagitis scores, anastomosis strength, sphincter pressure, weight loss, mortality, and blood vessel presence immediately after surgery.

Improving healing after esophagogastric surgery is critical to prevent life-threatening complications. BPC 157's ability to enhance tissue repair and counteract nitric oxide system impairments offers a promising therapeutic approach for surgical recovery and gastrointestinal health.

The study was conducted in rats, so results may not directly translate to humans. The exact molecular mechanisms of BPC 157's effects on the NO system require further investigation. The study type and evidence strength were not clearly defined.
