The mechanism of recovery from an acid load in primary cultures of rabbit choroid plexus epithelium (CPE) was examined, with emphasis on Na(+)-dependent antiports. Cells were incubated in saline solutions buffered to pH 7.38 with either HEPES or HCO3- plus 95% O2/5% CO2. Intracellular pH (pHi) was determined from the steady-state distribution of(More)

We investigated the effects of isoproterenol aryl glass beads on the electrical properties of cardiac muscle and related these to our previous results concerning biochemical and contractile effects (Ingebretsen et al., Circ, Rs., 40: 474-484, 1977). Beads (10-15) were placed near one end to guinea pig papillary muscles mounted horizontally in a bath(More)
