Response of chicken intestine to calcium omission on electrical potential and short-circuit.
A comparison of the endogenous PD and ISC, galactose transfer PD and ISC, and leucine transfer PD and ISC by rat and chicken intestine in a buffer with and without calcium, was made. The electrical activity in presence or absence of actively transported substrates was altered in the chicken intestine when a calcium-free buffer was used. No significant differences were observed with rat intestine.
