Does enzymatic digestion increase permeability of the outer blood-retinal barrier for high-molecular-weight substances?
The results indicate that heparan sulfate proteoglycan is important for the maintenance of the outer blood-retinal barrier and that lysosomal proteases may participate in damaging this barrier, causing increased permeability to high-molecular-weight substances.
Laparoscopic surgery for recurrent ileocolic Crohn's disease is safe and can lead to significant short-term benefit, including earlier discharge. Conversion increases the length of stay in hospital and the overall morbidity.
