Membrane dynamics in the parotid acinar cell during regranulation: a stereological study following isoprenaline-induced secretion.


Recently weaned male rabbits were injected either with 150 micrograms/kg isoprenaline in saline containing 0.01 M ascorbic acid or simply with the drug vehicle. Groups of drug-injected animals were killed at various time after injection. Parotid gland tissue samples from all animals were fixed, embedded and thin sectioned, and micrographs were prepared at… (More)
