Does a retinal-derived relaxing factor mediate the hypoxic vasodilation of retinal arteries?
Adherent retinal tissue mediates the hypoxic vasodilatation of bovine retinal arteries in vitro. Neither NO, prostanoids, adenosine, excitatory amino acids lactate or changes in pH seem to be involved in this hypoxic response.
This study indicates that BPD does not carry any increased risk for colorectal cancer. The complete postoperative restoration of insulin sensibility could exert a valuable protective action.
