title: Beta endorphin-like immunoreactivity in human aqueous humor and crystalline lens.
abstract: We measured the concentration of beta-endorphin (beta-End) in plasma, as well as in aqueous humor and crystalline lens removed during cataract surgery. beta-End was detected both in the aqueous humor and in the crystalline lens. The concentration of beta-End in the aqueous humor corresponded to almost the half of the plasma level (2.18 fmol/l and 4.55 fmol/l). Endogenous beta-End is presumed to enter the intraocular structures by passive diffusion.
