“…The terminal enzyme activity responsible for this (lactate dehydrogenase, LDH) has been measured in corneal epithelial cell extracts (Kuhlman and Resnick, 1958 ;Futterman and Kinoshita, 1959 ;Delbruck, 1963 ;So$ llner et al, 1966 ;Morisue, Shiba and Hoshino, 1967 ;Reim et al, 1971 ;Kaha! n and Ottovay, 1975 ;Doughty, 1996Doughty, , 1997 or epithelialendothelial cell extracts from corneas (Moore and Wortman, 1959 ;Graymore and McCormick, 1966 ;Graymore, 1966 ;Graymore and Power, 1967). Despite its repeated measurement, few details however appear to have been published on the actual quantities of the enzyme present in the corneal epithelium, on its essential properties or its localisation.…”
