Role of phospholipase A2 in oxidant-induced alteration in phosphate transport in primary cultured rabbit renal proximal tubule cells

Park KM, Ko SH, Woo JS, Jung JS, Lee SH, Kim YK

  • KMID: 2071540
  • Korean J Physiol Pharmacol.
  • 1998 Oct;2(5):601-609.
The present study was undertaken to examine the role of phospholipase A2 (PLA2) in oxidant-induced inhibition of phosphate transport in primary cultured rabbit renal proximal tubule cells. Uptakes of phosphate and glucose were...

Effects of small molecular antioxidants on cerulein-induced acute pancreatitis in rat

Choi JY, Kim KH

  • KMID: 2071543
  • Korean J Physiol Pharmacol.
  • 1998 Oct;2(5):629-635.
It has been suggested that oxygen free radicals are involved in the initiation process of acute pancreatitis, although its pathogenesis is not clear. This study evaluates the roles of oxygen radicals and...
