Extreme close-up microscopy-style photograph of a stained rat skeletal muscle cross-section, shot straight down through the microscope objective. Polygonal muscle fibers fill the frame in saturated magenta and pink eosin tones. A cluster of fibers on the left is neatly packed and uniform. On the right, the tissue is disrupted, with swollen gaps and thin, fibrous collagen strands in pale violet threading between damaged cells. A few tiny electric green fluorescent specks sit along one fiber edge as a subtle accent. Lighting is bright, even transmitted light with crisp focus at the center and soft falloff at the edges. The mood is analytical and tense, a rescue only partly complete. No text, no labels.

BPC‑157 zaštitio mišiće štakora od ozljede uzrokovane prekidom protoka krvi – s jednim zarezom

BY NOVA CHEN · 1. stu 2026.

Prekid protoka krvi u mišiću, a potom njegov brzi povratak, može uzrokovati veće oštećenje nego sam prekid. Nedavna studija na štakorima pokazala je da je BPC‑157, primijenjen na kraju ishemije, smanjio oksidativni stres, signalizaciju apoptoze i upalu, te djelomično povratio razinu VEGF‑a. Međutim, u istraživanju je bilo po šest štakora po grupi, jedna intraperitonealna doza od 20 µg/kg i samo dva sata reperfuzije. BPC‑157 nije odobren lijek, a rezultati su ograničeni na eksperimentalna životinja.
