Abstract
The levels of 5-hydroxytryptamine, octopamine, and dopamine in the glandular lobe of the corpus cardiacum and its nerve tract, the nervi corporis cardiaci II, have been measured by high-performance liquid chromatography in Locusta migratoria. All three amines are present within the glandular lobe, but only octopamine and 5-hydroxytryptamine were detected within NCCII. Immunohistofluorescence using antibodies against 5-hydroxytryptamine reveals that 5-hydroxytryptamine immunoreactive fibres are present within the nervi corporis cardiaci II and within the anterior regions of the glandular lobe. A few fibres pass over the surface of the glandular lobe. The report therefore provides the first description of the relative levels of 5-hydroxytryptamine, octopamine, and dopamine in the glandular lobe and the first description of 5-hydroxytryptamine immunoreactive fibres within the locust corpus cardiacum.Keywords
