Proliferating cell nuclear antigen (PCNA)-immunohistochemistry was used for demonstrating the spatiotemporal course of proliferation in the brains of embryonic (24 h) through postembryonic (5 days) zebrafish (Danio rerio). Parallel series of the same stages prepared according to the combined Bodian fiber silver-stain/cresyl Nissl-stain were used for(More)
The enteric nervous system (ENS) of the locust consists of four ganglia (frontal and hypocerebral ganglion, and the paired ingluvial ganglia) located on the foregut, and nerve plexus innervating fore- and midgut. One of the major neurotransmitters of the ENS, serotonin, is known to play a vital role in gut motility and feeding. We followed the anatomy of(More)
A role for endogenous cholecystokinin (CCK) in the control of gastric emptying of liquid glucose and maltose test meals in rhesus monkeys was assessed. Intragastric administration of a dose range (10-100 micrograms/kg) of the CCKA receptor antagonist devazepide produced a dose dependent acceleration of the emptying of 100 ml 300 mOsm test meals of glucose(More)
Motility of enteric plexus neurons in the grasshopper Locusta migratoria depends critically on the NO/cGMP signaling cascade. This is reflected in a strong NO-dependent cGMP staining in migrating enteric midgut neurons. In contrast, first cGMP immunoreactivity (cGMP-IR) in the foregut enteric ganglia was detected clearly after the main migratory processes(More)
