Intracellular ionic concentrations, membrane potential and Na+ and K+ flux were measured in a clonal rat glial cell line, C6. Intracellular concentrations of C6 cells were: (mmole/liter cell water) K+ 145 +/- 4 S.D., Na+ 18 +/- 4 S.D., Cl- 14 +/- 1 S.D. Cells maintained a steady state level of K+ over the duration of the experiments. This was substantiated(More)
Ouabain (5 X 10(-4) M) induced a 6-fold increase in intracellular Na+ and a 65% loss of cellular K+ in C6 glial cells which was accompanied by a 12 mV decrease in the resting membrane potential. Following ouabain washout intracellular ion concentrations and the membrane potential returned to control levels suggesting that C6 is capable of active Na+(More)
Cutaneous manifestations of type 1 cryoglobulinemia are usually related to vascular occlusion by noninflammatory thrombosis; rarely is leukocytoclastic vasculitis seen in type 1 cryoglobulinemia. We report the case of a 64-year-old male who presented with isolated cutaneous leukocytoclastic vasculitis that was initially attributed to essential mixed(More)
The diagnosis of myocardial infarction (MI) is established in patients with chest pain and equivocal electrocardiogram changes by demonstrating a rise in blood levels of creatine kinase MB (CK-MB) and/or an increase in cardiac troponin I (cTnI) or cardiac troponin T (cTnT). Previous studies have shown that levels of CK-MB are increased in the left ventricle(More)
