摘要：

The intracisternal (= ergastoplasmic) granules in the adipokinetic hormone-secreting cells of the glandular lobes of the corpora cardiaca in Locusta migratoria migratorioides represent accumulations of adipokinetic prohormones within cisternae of the rough endoplasmic reticulum. Solitary locusts have more and larger intracisternal granules than gregarious locusts. This coincides with the general locomotor activity and thus the energy metabolism in solitary locusts being quite different from that of gregarious locusts, which apparently has consequences for the amounts of adipokinetic hormones synthesized and/or released and, consequently, for the storage of these hormones in the intracisternal granules. These granules apparently function as supplementary stores of secretory material.
