...W. Breipohl; M. Leyendecker; K. von Tiesenhausen; F.H. Grus To further evaluate the pivotal role of epithelial cell proliferation in lens homeostasis, this study compares the principles of regional growth control in central and preequatorial bovine lens epithelial cells in culture. Central lens...

...Takako Ueda; Toshihiko Ueda; Donald Armstrong Lipid peroxidation was initiated with 5 m M ferric iron and aliquots of bovine or porcine retina, purified rod outer segments (ROS) and retinal pigment epithelium (RPE). After 30 min of oxidation, the lipid hydroperoxide content of the tissues increased...

...Michael J. Doughty The corneal epithelium was scraped from bovine eyes (Hereford or Holstein) within 3 h post mortem. The mitochondrial lysosomal fraction of the cells was assayed for hexosaminidase (HEX) and acid phosphatase (AP), and the membrane-soluble fraction for lactate dehydrogenase (LDH...

...S. Lerman; P. Mehta; H.A. Jones The de-aggregation and re-aggregation of α-crystallin derived from the dogfish and from the bovine lenses was studied by means of ultracentrifugation, ORD and CD spectroscopy, and by 2 immuno-chemical methods; the Ouchterlony technique and the quantitative complement...

...W. Rüssmann; B. Heisig Activities of GAPDH, GDH, LDH, MDH, T-1CDH, D-ICDH, G-6-PDH, and ME 2 were assayed in extracts of non-pigmented and pigmented cells prepared from ciliary processes of single bovine eyes. Results were correlated to cell count (levels of activity) and protein extracted...

...C. Ohrloff; O. Hockwin; D. Kaskel Phosphorylase, phosphoglucomutase and uridine diphosphoglucose pyrophosphorylase were investigated in bovine lenses. The dependence of their activities on protein content and on substrate concentrations was measured, and their K M values determined...

...C. Ohrloff; O. Hockwin Ketohexokinase (EC 2.7.1.3) is present in bovine lenses and facilitates fructose degradation to fructose-1-phosphate. The importance of this finding to lens carbohydrate metabolism is discussed. 28 11 1972 18 01 1973 9 12 2009 © 1973 S. Karger AG, Basel...

...R.I. Bashey; H.L. Kern Soluble collagen in bovine corneal stroma was determined by homogenizing and sequentially extracting the tissue with 0.45 m NaCl, pH 7.4, 0.5 m citrate buffer, pH 4.3, and 0.5 m acetic acid. Calf cornea contains about three times more soluble collagen than cow cornea. In both...

...C. Ohrloff; O. Hockwin; W. Licht The specific activity of ketohexokinase (EC 2.7.1.3), initiating the fructose utilization of lenses, depends upon age. In whole bovine lenses, this activity was found to be at a maximum at an age of about 9 months and, after subsequent decrease, the activity shows...

...H. Rink; J. Münnighoff; O. Hockwin The concentrations of Na + , K + and calcium as well as the water content in whole bovine lenses from 0.25 up to 0 25 years were determined. The data given in μmol/total lens or in μmol/g lens water show a linear increase with ageing for K + , Na + and Ca ++ ions...

Hockwin The enzymes UDPG pyrophosphorylase (EC 2.7.7.9), phosphorylase (EC 2.4.1.1) and phosphoglucomutase (EC 2.7.5.1) show their highest activity in the bovine lens equator, and lowest activity in the lens nucleus, independent of age. A maximum of activity for all...
