متن کاملOxygen consumption in the developing chick cornea.
Embryonic chick corneas at different stages of development were evaluated for O2 consumption. Some embryos were treated with thyroxine or thiouracil. In untreated animals, corneal QO2 (oxygen consumption/hr./mg. dry weight) decreased from 3.60 at stage 38 to 1.58 after hatching. The temperature coefficient Q10 increased from 1.55 at stage 40 to 2.03 after hatching. If O2 consumption is calculat...

متن کاملAcetylcholinesterase activity in the cornea of the developing chick embryo.
Activity of acetylcholinesterase (EC 3.1.1.7) and pseudocholinesterase (EC 3.1.1.8) was measured in extracts from chick corneas, in a developmental series from days 7-20 of incubation and at three ages after hatching. Enzyme activity was measured by the biphasic single-vial radiometric assay of Johnson and Russell using [3H-acetyl]choline as substrate. Pseudocholinesterase was inhibited with te...
متن کاملDifferential relative sulfation of Keratan sulfate glycosaminoglycan in the chick cornea during embryonic development.
PURPOSE To investigate structural remodeling of the developing corneal stroma concomitant with changing sulfation patterns of keratan sulfate (KS) glycosaminoglycan (GAG) epitopes during embryogenesis and the onset of corneal transparency. METHODS Developing chick corneas were obtained from embryonic day (E)12 to E18 of incubation. Extracellular matrix composition and collagen fibril spacing ...
