Magnetic field effects on calcium efflux and insulin secretion in isolated rabbit islets of Langerhans

Rabbit islets of Langerhans were exposed at 37 °C for 18 h to a low‐frequency‐pulsed magnetic field, generated in paired Helmholtz coils. Exposed islets showed a reduction of 26.1 ± 4.3% in 45Ca2+ content (P < .004). a reduction of 25.1 ± 6.3% in 45Ca2+ efflux (P < .006), and a reduction of 35...

Zusammenfassung:	Rabbit islets of Langerhans were exposed at 37 °C for 18 h to a low‐frequency‐pulsed magnetic field, generated in paired Helmholtz coils. Exposed islets showed a reduction of 26.1 ± 4.3% in 45Ca2+ content (P < .004). a reduction of 25.1 ± 6.3% in 45Ca2+ efflux (P < .006), and a reduction of 35.0 ± 8.7% (P < .002) in insulin released during glucose stimulation when compared with appropriate controls.
