Abstract Endothelial glycocalyx coats healthy vascular endothelium and plays an important role in homeostasis. Although cerebral capillaries are categorized as continuous, those the heart lung, they likely have specific features related to their function blood brain barrier. To test that idea, brains, hearts lungs from C57BL6 mice were processed with lanthanum-containing alkaline fixative, which preserves structure of glycocalyx, examined using scanning transmission electron microscopy. We...

Myocardial dysfunction occurs in patients with sepsis due to vascular endothelial injury. Recombinant human thrombomodulin (rhTM) attenuates injuries through glycocalyx (eGC) protection.We hypothesized that rhTM myocardial via the inhibition of injury during sepsis.Ten-week-old male C57BL6 mice were injected intraperitoneally 20 mg/kg lipopolysaccharide (LPS). In rhTM-treated mice, was at 3 and 24 h after LPS injection. Saline as control. To assess for eGC injury, intensity score measured 48...
