Fig. 7. C. antarcticus. VIP-IR nerve fibers surrounding a nonIR neuron cell body (n).
Nomarski optic. Immunoperoxidase x 700. Fig. 8. S. cabrilla. A strong VIP
immunoreactivity is present in epithelial endocrine cells and in numerous nerve elements.
Immunoperoxidase x 100. Fig. 9. P. macropterus. Sub P-IR nerve fibers surrounding
nonIR neuron cell bodies in the myenteric plexus. Immunoperoxidase. Nomarski optic x
600. Fig. 10. C. antarcticus. Insulin-IR nerve fibers in the muscular layer. Some of them
surround a faintly IR neuron cell body (arrow) . Immunoperoxidase x 200. Fig. 11. P.
macropterus. Brockmann body. Sub P-IR fibers near a blood vessel in the central region.
Immunoperoxidase. Nomarski optic x 700. Fig. 12. P. macropterus. Brockmann body. Sub
P-IR fibers surrounding a positive glucagon cell in the peripheral region.
