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 mišić podgraza kod pacova od povrede izazvane ishemijom – uz određene uslove

BY NOVA CHEN · 1. нов 2026.

Prekinuli ste protok krvi u mišić, a zatim ga vratili – povratak može izazvati ozbiljnije oštećenje nego sam zastoj. Novo istraživanje na pacovima pokazalo je da je primena BPC‑157 na kraju ishemije smanjila oksidativni stres, apoptozu i inflamaciju, te delimično povratilo nivo VEGF‑a. Histološka ispitivanja otkrila su bolju strukturu mišića i manje taloženje kolagena. Međutim, studija je imala samo po šest životinja po grupi, koristila je jedinu intraperitonealnu dozu od 20 µg/kg i dva sata reperfuzije. BPC‑157 nije odobren lek i ovo su isključivo podaci sa životinja, što ne opravdava njegovu upotrebu kod ljudi.
