We used brief bilateral carotid artery occlusion in gerbils to examine the effects of temperature on ischemia-induced inhibition of calcium/calmodulin-dependent protein kinase II activity and neuronal death. In normothermic (36 degrees C) gerbils, ischemia induced a severe loss of hippocampal CA1 pyramidal neurons measured 7 days after ischemia (28.4(More)
The activity of multifunctional calcium/calmodulin-dependent protein kinase II (CaM kinase II) has recently been shown to be inhibited by transient global ischemia. To investigate the nature of ischemia-induced inhibition of the enzyme, CaM kinase II was purified to greater than 1,000-fold from brains of control and ischemic gerbils. The characteristics of(More)
Platelet-derived growth factor (PDGF) is produced by a variety of normal and tumor cells in vitro. We have developed an enzyme-linked immunosorbent assay for the detection of the B-chain of PDGF. This assay can reliably detect 0.1 ng/ml of homodimeric recombinant PDGF B-chain and does not cross-react with recombinant PDGF-AA, epidermal growth factor, basic(More)
