Abstract
The present paper describes tyrosine
hydroxylase-like immunoreactivity in the ciliary
ganglion of monkey (Macaca fascicularis) and cat.
Under the light microscope, in the monkey, about 7.6%
of neurons were observed to be intensely stained, 27.7%
moderately stained and 32.5% lightly stained. In the cat,
1.2% of neurons were intensely stained, 5.4%
moderately stained and 10.1% lightly stained.
Ultrastructurally, tyrosine hydroxylase-like immunoreactivity
was observed in neurona1 somata, dendritic
profiles and axons in both monkey and cat. Tyrosine
hydroxylase-like immunoreactive dendritic profiles were
synaptically contacted by tyrosine hydroxylase-negative
axon terminals. In the monkey, tyrosine hydroxylase-like
immunoreactive fibres were observed to enter the ciliary
ganglion via the nasociliary nerve. Such fibres were
observed to course among neurons within the ganglion
and emerge in the short ciliary nerves. In contrast,
tyrosine hydroxylase-like immunoreactive fibres were
only occasionally observed in the cat.
