Figure 6. Effect of long-term application of 0 mM glucose on the basal [³H]CA release from rat carotid body.

Mean (± s.e.m.) time course of [³H]CA basal release from rat CB incubated with 5.5 mm glucose (controls, continuous line; n = 4) and from rat CBs incubated with 5.5 mm glucose for the initial 30 min and with 0 mm glucose between minutes 30 and 120 (experimental, discontinuous line; n = 7). Incubated solutions were collected every 10 min, each point representing the [³H]CA present in the solutions collected.
